Boeing E-3A Sentry AVR. E-3 is a universal, interference-protected, on-board reconnaissance and control radar point (DRLO). The design of this system was completed in 1976. The basis of the E-3 design is the passenger Boeing 707 (a new version based on the Boeing 767). In 1968, two companies, Westinghouse and Hughes, began developing a radar for a new aircraft. After intensive comparative tests, on October 5, 1972, it was decided to choose the Westinghouse radar. On January 26, 1973, after reviewing the work done and changing the requirements, the US Air Force made a decision to purchase 34 E-3A aircraft, which in the basic version were supposed to be adapted to detect only objects above the ground. In June 1979, an aircraft was flown with a new radar, designated AN/APY-2, capable of detecting naval and naval targets. Technical data: Maximum speed: 855 km/h, maximum ceiling 10,000 m, range: 1,610 km, weapons: aircraft without weapons
