The VITA 100 initiative reflects a broader inflection point in embedded computing. System architects are being asked to deliver more bandwidth, processing capability, and power density within the same ruggedized footprints that have defined VPX deployments for more than two decades. As those demands accelerate, the standards framework supporting highperformance embedded systems must evolve as well. Introduced in 2004, VPX has matured through years of deployment and refinement; VITA 100 represents the industry’s effort to define the next architectural step.
That transition began with a study group formed in May 2022 to define requirements for a nextgeneration VPX standard, followed by the launch of the VITA 100 working groups in January 2025. Those groups are developing a coordinated family of specifications intended to evolve OpenVPX and related mechanical standards while supporting greater connector density, faster protocol support, and increased power capacity. The architecture is being defined through a closely related set of standards (dot standards) spanning connectors, slot profiles, system management, power distribution, and validation.
Within that framework, the VITA 100 family is being organized around several core technical domains:
› System architecture and electrical interfaces
› Mechanical specifications
› System management
› Connector technology
› Power conversion and delivery
› Signal integrity
› Test and development methodologies
As that work progresses, those domains are expected to produce more than a dozen related standards, highlighting the scale of the transition from legacy VPX implementations to a more capable next-generation architecture.
At a strategic level, VITA 100 is intended to preserve the installed value of the VPX ecosystem while enabling a meaningful increase in system capability. The standard must be defined early enough to align with the point at which next-generation interconnect, processing, and power technologies become practical for deployment.
The effort is also shaped by more than two decades of VPX and OpenVPX deployment experience, with the goal of reducing implementation ambiguity and improving the path from specification to interoperable products.
Enhance interoperability and integration
One objective is to reduce the number of slot profiles by increasing connector density and effectively doubling usable pin count.
Another is to preserve chassis-level and architectural backward compatibility while enabling migration to newer implementations. In practice, that could allow a common chassis to support a hybrid backplane incorporating VITA 100 and/or VITA 65 plug-in cards.
Advance embedded computing capability
Additional technical goals include maximizing bandwidth through support for emerging high-speed protocols, including 400GBASE-KR4 and PCIe Gen6.
They also include increasing plug-in card powerhandling and thermal-dissipation capacity to support denser, higher-performance devices.
The effort further calls for an expanded 4U form factor capable of accommodating current-generation chipsets whose package sizes exceed the dimensional constraints of 3U implementations.
Finally, the group aims to qualify a representative design to VITA 47 environmental requirements and evaluate it against VITA 72 vibration criteria prior to public release, supported by a documented test plan and formal test procedures.
Taken together, these objectives make clear that VITA 100 is not simply an incremental revision of VPX. It is a deliberate effort to prepare the embedded computing ecosystem for a new performance regime while preserving the interoperability, ruggedization, and deployment flexibility that makes VPX broadly successful.
The VITA 100 effort is also bringing many new companies into VITA, both to help shape the standards and to gain early insight into their implementation. The initial set of standards is expected to be released this summer.

VSO study and working group activities
Standards within VITA may be initiated through the formation of a study group and developed by a working group. A study group requires the sponsorship of one VITA member, while a working group requires sponsorship of at least three VITA members.
Several working groups have current projects underway. Here’s a roundup of these projects:
VITA 46.32: VPX Connector Supporting 56 Gbaud Class Data Rates
Abstract: This standard defines a VPX connector that supports data rates to 56 Gbaud, for protocols such as 200GBASE-KR4 Ethernet and PCIe Gen 5. These connectors are intermateable to legacy VITA 46.X backplane connectors and follow the same form factor.
Status: Working group has developed a draft document that is ready for public review.
VITA 48.9: VPX AFT Cooling –Retractable Seals
Abstract: This standard defines an AFT module format, 3U and 6U, that uses retractable module rack seals to improve module-chassis seal durability, simplifies the design by eliminating tapered module and chassis features, and allows easy migration of existing CCA designs to an air-cooled module format.
Status: Working group is developing a draft document.
VITA 92: High Performance Cable –Ruggedized 10 Gbaud Bulkhead High Speed, D-Sub, Rectangular Connector for Copper Cables
Abstract: This standard defines a rugged standardized 10 Gbaud interconnect system with a high pin count and high-density, lightweight, rectangular connector (meets MIL-DTL-24308 physical envelope) for I/O. It can support multiple high- bandwidth protocols and power while optimizing SWaP [size, weight, and power] benefits in smaller systems with limited panel space availability.
Status: The public review phase has completed and the document is being prepared for publication.
Abstract: This standard complements the VITA 93.0 QMC standard by detailing the mechanical design of a mezzanine card installed on a carrier card or reartransition module, enabling the transition of QMC I/O signals to industry-standard connectors accessible through the carrier card’s or rear transition module’s front panel.
Status: Working group developing draft document.
Abstract: This standard defines a small-form-factor mezzanine based on the existing QMC standard but replacing the I/O connector with blind-mate
50-ohm or 75-ohm coaxial connectors. This is intended to allow for easy integration between mezzanines and carriers using high-performance coaxial connections for RF/IF or video applications.
Status: Working group developing draft document.
VITA 94.0-2024xNew:
Power Distribution Plug-In Module
Abstract: This standard provides requirements for building a power distribution plug-in module with digital controls that can be used in a VPX chassis. The plug-in module will fit within the standards envelope defined for VPX modules in the VITA 48.x
Status: Working group is developing a draft document.
Abstract: This document defines a standard for backplane connectors with EBO ferrules. EBO ferrules are available in multimode and single mode.
Status: Working group is developing a draft document.
Abstract: The VPX 100 suite of standards is an evolution of OpenVPX, VPX, and related mechanical standards while






By Ben Palmer

f you work in defense embedded computing, you have probably encountered MOSA, SOSA, VITA, and VPX in the same conversation and wondered exactly how they fit together. Add IEEE, SpaceVPX, PCI, and a handful of regulatory frameworks and the landscape can feel overwhelming fast. This guide breaks down each standard and framework; explains how they relate to one another; and clarifies what they mean for engineers designing, procuring, or integrating rugged electronic systems.
What is MOSA and why is it required for defense programs?
MOSA is the acronym for “modular open systems approach.” It is a technical and business strategy mandated by U.S. law under 10 U.S.C. 4401-4403 for all Major Defense Acquisition Programs (MDAPs) and, to the maximum extent practicable, for all U.S. Department of Defense (DoD) acquisition programs. MOSA is not a hardware specification or a product certification. It is a policy framework that requires programs to be designed with modular components and standardized, open interfaces that enable hardware and software to be added, replaced, or upgraded throughout the system life cycle without redesigning the entire system.
The DoD pursues MOSA for five primary reasons:
› Enhanced competition among vendors through open, modular architecture that allows components to be openly competed across suppliers.
› Easier technology refresh by replacing individual components without redesigning the entire system.
› Faster integration of innovation through operational flexibility to configure and reconfigure assets to meet changing requirements.
› Cost savings through component reuse across the acquisition life cycle and across programs.
› Improved interoperability by allowing hardware and software modules to be changed independently without cascading system-wide changes.
MOSA is enforced through contract language in the Defense Federal Acquisition Regulation Supplement (DFARS). The way MOSA actually gets implemented
in hardware is through consensus-based open standards, which is where bodies like VITA and IEEE, and consortiums like SOSA, become essential.
For VPX hardware suppliers and integrators, MOSA compliance is not a separate certification to pursue. It is the natural outcome of building products around consensus-based open standards. Wedgelocks and ejectors designed to VITA dimensional standards allow multivendor card sources in any compliant chassis, directly enabling the competitive, refreshable architecture MOSA requires. WaveTherm’s OpenCOTS program takes this further by providing open-reference heatframe designs to lower barriers for engineers building VITA-compliant systems.
What is SOSA and how does it relate to VITA and VPX?
SOSA, or the Sensor Open Systems Architecture, is a technical standard developed by The Open Group SOSA Consortium focused specifically on sensor systems for
defense programs. The goal of the SOSA Technical Standard is to promote interoperability, modularity, and reusability in sensor payloads and processing across different platforms and vendors. Where MOSA is the overarching DoD policy mandate, the SOSA approach is a specific implementation framework within that policy, targeting the sensor system domain.
The SOSA approach does not create its own hardware form factor. The SOSA Technical Standard uses OpenVPX (VITA 65) slot and module profiles as its hardware foundation. VITA defines over sixty distinct 3U VPX profiles; the SOSA approach selects approximately 15 percent of those and in some cases adds additional requirements on top. A SOSA aligned card is a VPX card built to specific VITA 65 profiles with additional SOSA requirements layered on. You cannot build SOSA aligned hardware without first conforming to the underlying VITA standards.
Like standard VPX, the SOSA approach supports the range of VITA 48 cooling methods. The cooling approach for a given system is defined at the slot-profile level, not mandated uniformly across all SOSA aligned deployments. For thermal and mechanical components, SOSA alignment adds no new requirements on top of the underlying VITA standards. The wedgelock geometry, heatframe dimensions, and thermal interfaces are defined by VITA. The SOSA Technical Standard inherits them.
VITA is an ANSI-accredited standards organization that writes and maintains open technical standards for rugged embedded computing hardware. VITA is the standards body that produces the building blocks that programs like the SOSA Technical Standard use and that policy frameworks like MOSA rely on. VITA standards define connectors, mechanical envelopes, backplane fabrics, cooling interfaces, and everything else that makes VPX cards and chassis physically and electrically interoperable across vendors.
Because VITA is ANSI-accredited and develops standards through a consensus-based process, VITA standards
qualify as “widely supported and consensus-based standards” under 10 U.S.C. 4401, the statute that defines MOSA requirements. This is what makes VITA the primary vehicle for MOSA compliance in embedded computing hardware. Programs that design to VITA standards are inherently building on the open, consensus-based interfaces that MOSA requires by law.
VITA 46: What is VPX?
VPX is a rugged embedded-computing standard used across defense, aerospace, and other harsh-environment applications. A VPX system consists of a chassis, a backplane, and plug-in cards (PICs) that slot into the backplane. The chassis provides the mechanical structure, cooling infrastructure, and power distribution, while the backplane carries high-speed data between cards. The plug-in cards are where the actual processing, sensing, communications, or I/O happens. VPX was introduced in 2007 as a successor to VMEbus, designed to support modern high-speed serial data rates while retaining the ruggedized Eurocard form factor that defense programs had relied on for decades. It comes in two primary sizes: 3U (smaller, lighter, common in size, weight, and power (SWaP)-constrained airborne and vehicle applications) and 6U (larger, higher power capacity, used in systems with more I/O and processing demands).
VITA 46 is the specific standard that defines VPX at its foundation. It specifies the base connector, mechanical format, and backplane interface that all VPX cards and chassis share. Rather than the parallel bus architecture of VME, VITA 46-compliant backplanes use high-speed serial fabric protocols including PCIe, Ethernet, and RapidIO, giving VPX the bandwidth needed to feed modern processors and FPGAs. VITA 46 is one of the primary MOSA-enabling standards for embedded computing in defense programs. Programs using VPX can source boards from multiple competing vendors without chassis redesign, directly enabling the multi-vendor competition and technology refresh that MOSA requires.
VITA 48: How does VPX handle thermal management?
VITA 48, also known as REDI [Ruggedized Enhanced Design Implementation], is the standard family governing thermal management and mechanical design for VPX modules. Each sub-standard defines a distinct cooling approach suited to a different deployment environment. Selecting the right VITA 48 method is a system-level decision driven by available cooling infrastructure, power density, and environmental requirements.
VITA 48.1 – Air Cooling: VITA 48.1 uses airflow as the primary means of removing heat from VPX modules. This approach is typical for development and lab setups, where a sealed chassis and harsh-environment thermal management are not required. Certain field-deployed systems also run air cooling where the operating environment allows it.
VITA 48.2 – Conduction Cooling: VITA 48.2 is the dominant standard for deployed rugged military systems. Heat generated by the circuit card travels through the heatframe, through the wedgelock, and into the chassis cold wall. The wedgelock is not just a mechanical retainer. It is the critical thermal interface in the heat path, and its clamping force, contact surface, and thermal cross-section directly determine how much heat moves out of the card. VITA 48.2 also defines Two-Level Maintenance (2LM) requirements, meaning that wedgelocks and ejectors must enable field technicians to swap cards without specialized tools or depot-level support.
WaveTherm designs wedgelocks and ejectors specifically to VITA 48.2 requirements. The OpenCOTS program provides standardized, open-reference heatframe kits for engineers building VITA 48.2 systems, thereby removing one of the most common development bottlenecks: getting a manufacturable heatframe design without engaging a custom supplier for a small-run project.
VITA 48.4 – Liquid Flow-Through Cooling: VITA 48.4 routes liquid coolant directly through the module, drawing from the host vehicle’s thermal-management system. It
targets vehicle-integrated applications where power density is high enough to exceed what conduction cooling can handle. Because the coolant source is the vehicle itself, implementation details are generally specific to each platform.
VITA 48.5 – Air Flow-Through Cooling: VITA 48.5 circulates air across a heat exchanger that is isolated from the module’s internal electronics. Keeping the airstream separate from the electronics makes this approach practical in environments where particulates or contaminants in the air would otherwise be a concern.
VITA 48.7 – Air Flow-By Cooling: VITA 48.7 moves air across fins integrated into the outer surface of the module. Thermal performance depends heavily on the fin geometry and available airflow rate, so the heatsink design is typically optimized for the specific application.




VITA 48.8 – Air Flow-Through Cooling with Finned Heat Exchanger: VITA 48.8 passes air through a structured fin array built into the module, with configurable flow paths to improve thermal efficiency. It is worth noting that higher-performance forced-air designs do not always outperform conduction cooling when power density climbs. A system-level comparison against VITA 48.2 is worthwhile before settling on an air-cooled approach.
VITA 65: What is OpenVPX and why does it






Highly useful as stand alone or in combination with other backplanes, with or without RTM connectors. Multiple units can be topology wired using MERITEC VPX Plus cables. The Dawn family of one-slot OpenVPX test station and development backplanes gives engineers the ability to perform compatibility tests and easily reconfigure payload module profiles and slot interoperability to meet custom requirements.






VITA 65, known as OpenVPX, is the system-level interoperability standard built on top of VPX. VITA 46 defines the physical hardware, while VITA 65 defines how to assemble that hardware into a working, interoperable multi-vendor system. OpenVPX does this through three profile types: Slot Profiles (what a chassis slot accepts), Backplane Profiles (how slots are interconnected), and Module Profiles (what a PIC supports). All three must align for a multivendor system to function correctly.
OpenVPX is the layer where multivendor interoperability becomes predictable and guaranteed rather than theoretically possible. When a program specifies an OpenVPX slot profile, any PIC from any manufacturer meeting that profile will insert into that slot and communicate across the backplane. This is the competitive, refreshable architecture MOSA requires at the hardware level. SOSA selects its hardware profiles from OpenVPX and adds additional requirements on top, making conformance to the relevant VITA 65 profiles the prerequisite for any SOSA aligned hardware.
is SpaceVPX?
VITA 78 is an adaptation of the VPX standard designed specifically for space applications, including satellites, launch vehicles, and spacecraft. Standard VPX was designed for ground, airborne, and naval environments. Space introduces fundamentally different challenges: vacuum conditions that eliminate convection cooling, ionizing radiation that damages standard electronics, extreme thermal cycling between sunlight and eclipse, severe launch vibration and
shock loads, and outgassing requirements that rule out many materials common in ground systems.
In a SpaceVPX system, conduction cooling is not a preference but instead is a requirement. With no atmosphere, every module must transfer heat conductively through the chassis structure, which ultimately radiates to space. This reality makes the mechanical interface between the card, the wedgelock equivalent, and the chassis rail critical in a way that is even more absolute than in ground systems. SpaceVPX also requires radiation-tolerant or radiation-hardened components and strict outgassing-compliant materials for all hardware in the thermal path.
WaveTherm’s ejectors are fully compliant with VITA 78.0, and OpenCOTS heatframe kits are available for VITA 78.0 applications.
What is the difference between PCI, CompactPCI, and VPX?
PCI, or Peripheral Component Interconnect, is a parallel bus standard developed by Intel in the early 1990s for desktop computer expansion cards. PCI itself is not used in modern VPX systems, but it is the ancestor of PCIe (PCI Express), which is one of the primary high-speed serial fabrics used across VPX backplanes today. PCIe is governed by the PCI-SIG (PCI Special Interest Group) and qualifies as a MOSA-enabling standard through its consensus-based development process.
CompactPCI (cPCI), developed by PICMG in the mid-1990s, adapted the PCI bus for the Eurocard mechanical format used in rugged industrial and defense applications. cPCI was the dominant rugged embedded computing platform through the late 1990s and 2000s before being displaced by VPX in high-performance defense applications. VPX replaced the parallel PCI bus with high-speed serial fabrics while keeping the ruggedized Eurocard mechanical heritage. Many legacy defense programs still run on cPCI hardware, and MOSA-driven technology refresh is one of the primary forces moving those programs toward modern VPX architectures. WaveTherm’s ejectors serve cPCI platforms in addition to VPX,
covering the full range of Eurocard-based board retention needs.
What role does IEEE play in VPX systems?
IEEE, the Institute of Electrical and Electronics Engineers, is one of the world’s largest technical standards organizations. IEEE is relevant to VPX because VITA builds several of its standards on top of IEEE foundational standards. IEEE is also recognized as an ANSI-accredited, consensus-based standards body, meaning that IEEE standards qualify as MOSA-
enabling standards under 10 U.S.C. 4401 the same way VITA standards do.
IEEE 1101.2 – The Mechanical Foundation for Conduction-Cooled VPX: IEEE 1101.2 is the most directly relevant IEEE standard for VPX thermal and mechanical design. It specifies the mechanical design and thermal interface requirements for conduction-cooled Eurocards. VITA 48 builds directly on IEEE 1101.2, and 6U VPX explicitly requires IEEE 1101.2 conduction- cooled envelope compliance. This requirement makes it the







Accelerate mission deployment with the same backplane and integrated plug-in card payload set aligned to VITA, SOSA® and CMOSS. Includes chassis management, power and rugged enclosure for EO/IR, EW, SIGINT and C5ISR applications.

foundational document for wedgelock thermal interface geometry and heatframe design in VPX systems.
A wedgelock or heatframe that conforms to VITA 48.2 is by extension conforming to the underlying IEEE 1101.2 mechanical baseline. The two standards are layered, not competing. IEEE 1101.2 sets the physical envelope for conduction-cooled Eurocards. VITA 48 adds VPX-specific requirements on top of that baseline. (Figure 1.)
Other IEEE standards in the VPX ecosystem
IEEE 802.3, the Ethernet standard, is used in VPX backplane communications. VITA has developed interface standards for handling IEEE 802.3 protocol layers across VPX backplanes. IEEE 1149.1, also known as JTAG, is the boundary scan standard used for test and debug access in VPX board designs. IEEE 1386, the PCI Mezzanine Card standard, is a legacy reference that provides historical context for understanding how VPX evolved from earlier mezzanine form factors. These standards operate at the electrical and protocol level and have no direct effect on thermal or mechanical components in the system.
Beyond the technical standards that govern hardware design, defense electronics suppliers operate within a set of regulatory and compliance frameworks. These are not design specifications but legal and contractual requirements that affect how products are manufactured, exported, and sold into defense programs.
› ISO 9001 [Quality Management]:
The foundational quality-management system certification. Defense customers commonly require ISO 9001 as a baseline supplier qualification, demonstrating documented and repeatable processes for design, manufacturing, and quality control. WaveTherm is ISO 9001-certified.
› ITAR [International Traffic in Arms Regulations]: U.S. State Department regulations governing the export and import of defense

articles and technical data listed on the U.S. Munitions List. ITAR registration is a nonnegotiable requirement for suppliers selling thermal or mechanical solutions into U.S. defense VPX programs. It restricts how hardware and data can be shared with foreign nationals or entities without an export license.
› DFARS [Defense Federal Acquisition Regulation Supplement]: DoD-specific additions to the Federal Acquisition Regulation that govern defense contracts. DFARS is how MOSA policy becomes a contract obligation. DFARS Part 207.106 specifically requires modular, open architectures to enable competition for upgrades. DFARS 252.227 governs technical data rights relevant to MOSA interface documentation requirements.
› RoHS [Restriction of Hazardous Substances]: A European Union directive restricting certain hazardous materials in electronics. Defense and military electronics are generally exempt from RoHS in both the EU and the U.S. Military programs frequently specify non-RoHS (leaded) solder processes for reliability reasons, as lead-free solder is more susceptible to tin-whisker growth in highreliability applications.
› REACH [Registration, Evaluation, Authorisation and Restriction of Chemicals]: A European Union regulation governing chemical substances in products sold in EU markets. REACH compliance is most relevant for suppliers with European market exposure. For purely domestic U.S. defense programs, REACH has limited direct applicability, though awareness of restricted substances in manufacturing materials remains good practice.
In short, MOSA is the policy driver that pushes defense programs toward modular, upgradable systems, while VITA and IEEE provide the consensus-based technical standards that make that goal practical in hardware. Within that structure, VPX and OpenVPX define the physical and interoperability foundation for rugged embedded computing, and the SOSA approach builds on those standards to narrow choices and improve consistency for defense sensor platforms. Together, these frameworks help engineers and program teams reduce vendor lock-in, simplify technology refresh, and build systems that are more interoperable, maintainable, and ready to evolve over time.

Despite the proliferation of high-speed serial fabrics and switched architectures, VMEbus remains in widespread use across defense platforms worldwide. Introduced more than four decades ago, VME continues to underpin deployed systems in naval combat management, radar processing, electronic warfare, avionics, and C4ISR applications.
In commercial electronics, architectural longevity is often viewed as a limitation. In defense systems, it is often an asset. Military platforms are developed, qualified, deployed, and sustained over timelines that can span decades. Computing architectures selected at program inception may still be operational – and mission-critical –long after their commercial counterparts have disappeared.
VMEbus is a case in point. First standardized in the early 1980s, VME has served as a foundational embedded computing architecture for defense systems for over forty years. While newer standards such as VPX and Ethernet based fabrics now dominate high-performance designs, VME continues to be specified, deployed, and supported in both new and legacy programs.
This persistence is not accidental. Rather, it reflects deliberate technical design choices and a strong alignment with defense program realities. Understanding VME’s legacy offers insight into how “mature” technologies can remain strategically relevant in mission critical environments.
My personal experience with VME began in 1999, when I joined Radstone Technology as a Product Manager. Much like VME itself, which has continuously evolved over the past 30 years, Radstone also underwent significant transformation – first becoming part of General Electric, then Abaco, and ultimately joining the AMETEK portfolio. Notably, we continue to supply to this day, a specific VME product that was being introduced to the market at that time. This PowerPC based single board computer has been deployed
across a remarkably diverse set of applications, including a naval torpedo, an airborne targeting pod, and a ground control station for an unmanned aerial vehicle (UAV). While the product’s lifecycle has not been without challenges, the implementation of a well defined DMSMS strategy has clearly demonstrated that it is possible to extend the operational life of a single board computer – typically expected to be in the 7- to 9-year range –to well beyond 25 years. In this respect, VME technology continues to demonstrate exceptional longevity and relevance
Origins of VME and early defense adoption
VME was introduced in 1981 by a consortium led by Motorola, Philips, and Mostek. Unlike proprietary buses common at the time, VME was conceived as an open, vendor-neutral standard, later formalized under IEEE 1014.
Several attributes drove early defense adoption:
› Processor independence, allowing multiple CPU architectures to coexist.
› Mechanical standardization based on Eurocard formats.
› Published specifications, enabling multivendor competition.
For defense organizations seeking to avoid vendor lock-in and mitigate long-term obsolescence risk, these characteristics were immediately attractive. By the late 1980s and early 1990s, VME had become a de facto standard for naval combat systems, radar processors, and military test equipment.
Of course, vendors have always sought to achieve some degree of lock-in, and companies such as Abaco developed defined board families and technology-insertion roadmaps that preserved pinouts across multiple generations of VME products. This approach encouraged customers to upgrade to fully compatible replacements while minimizing integration costs. PowerPC architectures often went hand in hand with VME, and Abaco’s PowerX family evolved over many years – from single-core processors such as the 100 MHz Motorola 603e to the 8-core QorIQ T2081 running at 1.2 GHz.
Nevertheless, the fundamental architectural strengths of VME continued to attract users, even as alternative standards such as VPX and CompactPCI became available.
Core architectural characteristics
Shared parallel backplane architecture: At its most fundamental level, VME is a shared parallel bus implemented on a passive backplane (Figure 1). Plug-in modules communicate via common address, data, and control lines routed across the chassis.

While modern standards favor switched point-to-point links, the shared bus model offers several defense-relevant advantages, such as predictable latency, transparent hardware behavior, and simpler fault analysis. These attributes are especially valuable in real-time and safety-critical environments.
Asynchronous operation: VME employs an asynchronous transfer protocol using handshaking rather than a system-wide clock. While this approach limits maximum throughput compared to synchronous fabrics, it enables interoperability between modules of differing speeds, incremental technology insertion without timing redesign, and stable operation across wide environmental ranges
By Travis Rupp, Director of Product Management
The processing demands on small airborne platforms are not small. Loitering munitions, UAS, launched effects, and packable electronic warfare systems are expected to run sensor interface, AI inference, and real-time signal processing workloads that previously required a full rack of embedded computing hardware. The V3211 is built to fill that gap.
The V3211 is a rugged, double-width VITA 93 QMC System on Module (SoM) featuring the AMD Versal® AI Edge Gen 2 Adaptive SoC. It integrates Arm® Cortex®-A78AE application processors, Cortex-R52 real-time processors, AI engine cores, and large FPGA fabric on a single piece of silicon. No separate CPU board. No discrete GPU. No additional FPGA card. The heterogeneous compute stack fits on the module.
Memory and I/O scale to match. The V3211 carries 36 GB of LPDDR5X SDRAM at up to 6400 Mbps, PCIe Gen5 x4 connectivity via dedicated CPM5 controller, and high-speed serdes supporting up to 32G PL lanes. The module deploys into VNX+, 3U/4U/6U VPX, PCIe, CompactPCI, and most carrier card systems.

What separates the V3211 from other small form factor solutions is not just size – it is that the VITA 93 form factor and interfaces comply with the Modular Open Systems Approach (MOSA) in a less-than-3U VPX small form factor (SFF).
The FPGA fabric supports New Wave Design IP cores for Fibre Channel, ARINC-818, sFPDP, and Aurora, covering the legacy protocol requirements airborne and ground platforms still carry. VITA 93 and VITA 47 compliance means the module meets the open architecture requirements programs are mandated to follow, not as an afterthought, but by design.
For programs where the platform cannot grow to fit the compute requirement, the V3211 brings the compute requirement down to fit the platform. https://newwavedesign.com

For defense systems that integrate hardware across multiple technology generations, asynchronous operation reduces integration risk.
Multi-master capability: VME was designed from the outset to support true multimaster operation (Figure 2). Any capable module may request bus ownership and initiate transactions, subject to arbitration.
This capability supports advanced system architectures, including distributed signal processing, redundant controllers, and graceful degradation in fault conditions. In contrast to architectures reliant on a single root complex, VME inherently supports decentralized control.
As seen in Figure 2, each bus master asserts a bus request (BRx) to the arbiter. The arbiter resolves contention and returns a corresponding bus grant (BGx), allowing the selected master to access shared bus resources.
Explicit addressing model: VME defines multiple address spaces – notably A16, A24, and A32 – each associated with specific use cases (Figure 3). Address decoding is typically hardware defined and static.
While less dynamic than plug-and-play enumeration models, this explicit approach offers deterministic behavior, simplified system verification, and easier long term maintenance. These characteristics align well with defense certification and assurance requirements.
Evolution without disruption: Rather than stagnating, VME has evolved gradually to meet emerging requirements.
VME64 and VME64x: VME64 (VITA 1) increased data widths and power delivery while retaining backward compatibility. VME64x (VITA 1.1) added features such as geographic addressing, hot-swap support, and improved connector reliability. Crucially, these extensions preserved interoperability with legacy hardware.
Enhanced transfer modes: Technologies such as 2eSST (VITA 1.5) improved throughput into the hundreds of megabytes per second – sufficient for many defense workloads where determinism and reliability outweigh peak bandwidth.
Coexistence with VPX and modern architectures: VME is increasingly deployed alongside newer technologies rather than in isolation. Hybrid systems may combine VPX for high-performance processing with VME for legacy I/O, control, or missionproven subsystems.
This layered approach enables evolution without disrupting deployed capability – a recurring theme in defense system design.
Environmental robustness and mechanical design: Defense platforms impose demanding environmental constraints, including shock, vibration, temperature extremes, humidity, and electromagnetic interference. VME’s mechanical ecosystem has evolved specifically to address these challenges.
Eurocard mechanics and ruggedization: VME modules use standardized 3U, 6U, and 9U Eurocard formats with rigid front panels, injector ejector hardware, and secure card retention. For harsh environments, conduction-cooled variants compliant with IEEE 1101.x standards are widely deployed.
These features make VME particularly well-suited to use in naval vessels, ground vehicles, and airborne mission systems.


VME across defense domains
Naval combat systems: Naval platforms represent one of the strongest longterm bastions of VME usage. Combatmanagement systems, sonar processors, and fire-control subsystems often depend on VME architectures that have been incrementally upgraded over decades. The ability to sustain and evolve these systems without wholesale redesign is a decisive advantage in naval procurement.
Radar and electronic warfare (EW): Radar and EW systems frequently require deterministic latency, high I/O density, and distributed processing. VME’s shared memory access and multimaster operation have historically met these needs well.
Even as processing performance has migrated to FPGAs and multi core CPUs, VME backplanes continue to provide reliable integration for sensor interfaces, timing modules, and control processors.
Avionics and mission systems: In military avionics – particularly in legacy and rotary wing platforms – VME remains present where proven certification paths and predictable real-time behavior are prioritized over raw bandwidth.
The maturity of VME board-support packages and RTOS [real-time operating system] integrations reduces software risk and life cycle cost.
C4ISR and ground systems: Commandand-control and intelligence systems often favor architectures with high avaiability and maintainability. VME’s multi-vendor ecosystem and field-proven reliability continue to support these objectives.
Despite the availability of newer architectures, VME persists in defense systems for several pragmatic reasons:
› Long program life cycles demand continuity
› Certification costs discourage wholesale architectural change
› Supply-chain diversity supports long term availability
› Performance sufficiency meets mission requirements in many roles
In many cases, VME is not the fastest option – but it is the least risky.
However, even with the benefits described above and its true longevity, matching availability to program lifetimes cannot be achieved without a robust obsolescence-management strategy.
A robust DMSMS strategy is essential for sustaining VME-based products over long program life cycles, which may extend for several decades in defense, aerospace, and industrial systems. While VME itself has demonstrated exceptional architectural longevity, the underlying components – processors, memory devices, ASICs, and support silicon – are subject to commercial obsolescence cycles that are far shorter than the operational life of the platforms they support.
Without a proactive DMSMS approach encompassing life cycle forecasting, last-time-buy planning, form/fit/function replacements, and controlled technology refresh, systems face increased cost, schedule risk, and potential loss of capability. A well-executed DMSMS strategy therefore enables continuity of supply, preserves certification status, and mitigates integration risks, ensuring that VME products can reliably support long-term programs well beyond their original commercial design horizon.
The legacy of VME in defense applications is defined not by obsolescence resistance alone, but by architectural suitability. Its deterministic behavior, rugged mechanical ecosystem, backward compatibility, and open standard governance have proven remarkably well-matched to military requirements. Even four decades after its introduction, VME remains a relevant and trusted building block in defense electronics. In an industry where reliability, predictability, and sustainment matter as much as raw performance, VME’s continued presence is not surprising – it is instructive
