Who We Are
The Applied Physics Laboratory (APL) is a not-for-profit center for engineering, research, and development. Located north of Washington, DC, APL is a division of one of the world's premier research universities, The Johns Hopkins University (JHU). The Laboratory has been a major asset to the nation since it was organized to develop a critical World War II technology in 1942. We recruit and hire the best and the brightest from top colleges, and 68% of our recruits are engineers and scientists. We work on more than 600 programs that protect our homeland and advance the nation's vision in research and space science, at an annual funding level of about $980 million.
What We Do
APL solves complex research, engineering, and analytical problems that present critical challenges to our nation. That's how we decide what work we will pursue, and it's how we've chosen to benchmark our success. Our sponsors include most of the nation's pivotal government agencies. The expertise we bring includes highly qualified and technically diverse teams with hands-on operational knowledge of the military and security environments. We offer an outstanding and creative staff, augmented by world-class facilities.
