Innovation - Physics

Critical Challenges, Critical Contributions. A division of one of the world’s premier research institutions, the Johns Hopkins University Applied Physics Laboratory is a national resource for engineering, research and development. More than 4,300 scientists, engineers and support staff solve the country’s toughest technology, national security and space science challenges from APL’s 399-acre campus in Laurel, Maryland, just 20 miles north of the nation’s capital.

PL’s first task in 1942 was to find better ways for ships to defend themselves against enemy air attacks – the result, a proximity fuze that made anti-aircraft shells significantly more effective, was one of the war’s most valuable technology developments. This success led to a strong partnership between the government, Johns Hopkins University and APL that has endured for more than six decades.


APL’s depth of expertise allows it to take on a broad range of projects. APL-built spacecraft are flying across the solar system, sailing past Mercury, taking 3-D photos of the sun, and heading
