The Israel Weapon Industries GL 40/40-S is a new standard single shot grenade launcher that integrates with the Tavor assault rifles. (JP Husson)
also known as the Type 03, with a 20Â mm airbust grenade launcher. Rather surprisingly the launcher is a single-shot type with no magazin, that requires each round to be manually loaded and reloaded after every firing. Grenades are pre-programmed and loaded into a manually operated bolt-action. The Future Two other shoulder-fired launchers using precision airburst fuzing: the famous XM25, developed by Alliant Techsystems and Hecker und Koch (the target acquisition/fire control system is developed by L-3 IOS Brashear), which fire the LV 25 x 40B grenade (HEAB, but also Thermobaric, Flechette, AP, etc.); and the Korean DAW (Dual-barrel Air-burst Weapon) K11 of S&T Daewoo (now S&T Motiv), which is in service in Republic of Korea Army and combines a 20 mm grenade launcher with a 5.56 mm assault rifle, so is similar in concept to the abandoned US XM29. The K11 DAW grenade launcher uses 20 x 30 mm ammunitions feed by way of the 6-round detachable box magazine and actuated through bolt-action mechasnism. It weitghs 6,1 kg and has a maximum effective range of 500 metres (20 x 30B ammunition, type HEAB K-167). A most interesting Western launcher project is from Rheinmetall, who have developed a recoil buffering system that enables their powerful 40 mm MV Velan ammunition to be fired from lightweight guns (Velan medium velocity using the infra-red fuze setting and grenades as
the Reinmetall HV ammunition). This is being applied to two launchers; the single-shot Cerberus and the magazinefed self-loading Hydra, which are intended to fire both LV and MV ammunition including precision airburst rounds, with the addition of the Rheinmetall Multi-Ray fire control unit. The Cerberus in either under-barrel or stand-alone form, with a weight of 2,1 kg and 2.8 kg respectively. The Hydra, which can be used in the self-loading mode, the three-position selector having a safe, semi-auto and three round burst (a full auto version being easily developable on customers request), weight will be of about 4 kg empty (different magazines will be available, with 3, 6 and 10 rounds capacity, and a drum magazine for 9 rounds). Recently, 40 mm LV systems have also appeared, from Israel Military Industries (IMI) using inductive fuze setting in a modified launcher as part of their MPRS (Multi-Purpose Rifle System) and from ST Kinetics using remote fuze , setting.
