Happy birthday to us! A few days late — we were out celebrating 😁💃🎉 Thanks, MIT Lincoln Laboratory friends!
DYK: On 18 September 1961, Lincoln Laboratory completed construction of the Haystack radome in Westford, Massachusetts. The radome, at the time the world’s largest metal space-frame structure, housed a 120-foot diameter fully steerable paraboloidal Cassegrain antenna. The U.S. Air Force funded this facility to support advanced research in radar technology and space communications. Herbert Weiss, associate head of the Radar Division, served as Haystack's chief designer and project leader.
The journey to build the Haystack facility began in March 1958 when Group 45, Airborne Radar Systems, submitted a proposal for a high-performance radar research facility. The initial design did not include a radome, but by late 1958, the team recognized the need to protect the antenna from inclement weather. Thomas King, Group 71, Design Engineering, served as project engineer for the radome. Construction crews began building the radome in June 1961, placing lightweight fiberglass panels coated with chlorinated polyester resin onto a 134-foot-high steel space frame. The panels provided durability, weather resistance, and minimal transmission loss, allowing the radar to operate in all weather conditions. The radome’s design drew inspiration from earlier rigid radome prototypes developed by Lincoln Laboratory, including geodesic domes tested in extreme environments such as near the summit of Mount Washington in New Hampshire.
