Innovation and Impact

At APL, we create technologies and innovations to protect our homeland and warfighters, enable teamwork between people and machines, expand the limits of computing power, and improve the ability of people to survive in the most remote parts of the globe.

By combining creativity and technical expertise with a culture of risk-taking — brought together in cutting-edge collaboration spaces, labs, and test facilities across our campuses — we tackle increasingly difficult challenges with impacts across multiple domains.
