Johns Hopkins University Applied Physics Laboratory

The Johns Hopkins University Applied Physics Laboratory (APL) is a not-for-profit university-affiliated research center that serves as a technical resource for the Department of Defense, NASA, and other government agencies. The laboratory was founded on March 10, 1942, three months after the United States entered the Second World War, and was assigned the task of finding a more effective way for ships to defend themselves against enemy air attacks. It designed, built and tested the radar proximity fuze known as the VT fuze.¹ Its 2025 description states that "APL's UARC sponsor is the U.S. Navy," and that each university affiliated research center has a primary sponsor and a primary contract that define the limits of competition; the same document says APL performs sponsored work for "the Intelligence Community," along with the DOW, NASA and other agencies.² In the context of the Cold War, APL scientists were assigned to oversee Project Pandora, a classified program initiated by DARPA to duplicate the effects of the Moscow Signal³.

Under the direction of Richard S. Cesaro, APL scientists constructed an elaborate facility inside the Walter Reed Army Institute of Research. Here, primates were irradiated with microwave beams with a power density similar to that of the Moscow Signal. Cesaro became convinced of the harmful nature of these beams, concluding they adversely affected the internal organs, including the brain, of primates, and could lead to conditions like Alzheimer's Disease³.

APL was also involved in a $1 million study funded by the State Department to investigate the health effects on U.S. Embassy in Moscow personnel exposed to the Moscow Signal. This study, released in November 1978, found "no convincing evidence" that employees suffered "adverse health effects as of the time of this analysis," a finding that was controversial given the concerns raised by scientists like Cesaro and Allan H. Frey³.

Navy and space programs

In 1957 two APL physicists, William Guier and George Weiffenbach, developed a method of tracking satellites from the Doppler shift in the signals of the Soviet Sputnik, and in 1958 APL invented the Doppler-based Transit satellite navigation system, which the laboratory states was fully operational in 1964 and improved the ability of U.S. submarines to determine their positions.⁴ In 1974 APL tested an engineering development model of the AN/SPY-1 radar for the Aegis combat system system aboard USS Norton Sound, and in 1981 USS Ticonderoga became the first vessel with the Aegis combat system, with APL as technical advisor.⁵ APL built the NEAR spacecraft (launched February 22, 1996; orbited 433 Eros on February 14, 2000), MESSENGER (launched August 3, 2004), New Horizons (launched January 19, 2006; Pluto flyby July 14, 2015) and the Double Asteroid Redirection Test spacecraft (launched November 24, 2021, for NASA's Planetary Defense Coordination Office).⁶⁷
