 Applied Physics Laboratory

The Applied Physics Laboratory (APL) is a research and development organization that focuses on applying the principles of physics and engineering to address practical challenges, particularly in areas such as national security, space exploration, and healthcare. APL is often associated with Johns Hopkins University, as it was founded as a division of the university in 1942. The laboratory conducts a wide range of projects, including work on advanced technologies for defense systems, undersea warfare, missile defense, satellite systems, and space science.
