Johns Hopkins University Applied Physics Laboratory

The Johns Hopkins University Applied Physics Laboratory (APL) is a not-for-profit, university-affiliated research centre that solves complex research, engineering and analytical problems for the United States. Founded on 10 March 1942, three months after the country entered the Second World War, as part of a federal effort to mobilise scientific resources, it became a major contributor to guided missile and submarine technology and has maintained its strategic relationship with the government and Johns Hopkins University for more than eight decades. APL is located at 11100 Johns Hopkins Road, Laurel, Maryland, and provides technical expertise, prototyping, research and development and analysis across national security and scientific challenges, documented in an annual report whose 2025 edition highlights its technical achievements, partnerships and people.

Mission areas

• Civil space flight, including spacecraft and instruments for NASA such as the Dragonfly rotorcraft mission to Saturn's moon Titan featured on its site
• Cyber operations, global health and other national security mission areas
• Research and exploratory development in alternative computing paradigms, biological and chemical sciences, physics, electronic materials and devices, extreme and multifunctional materials, and design, engineering and fabrication
• Strategic technology solutions, with roboticists, modelling experts, AI researchers and chemists working together to create next-generation materials for sponsors

Facilities and education

Recent news on the site covers a Johns Hopkins collaboration expanding access to maritime testing, a new 36 ft research vessel, an additively manufactured quantum dot waveguide sensor and work with the US Navy. APL publishes the Johns Hopkins APL Technical Digest and conference proceedings, and runs education programmes including STEM outreach for students and teachers through its STEM Program Management Office, internships, a summer centre for space science, fellowships for government employees, programmes for new graduates and executive and professional education.

Shows

Johns Hopkins APL appears in the sponsor and exhibitor lists of the Space Symposium 2027, where it is listed as a co-sponsor, and the AMOS Conference 2027, where it is a Lokahi sponsor.
