WRIGHT-PATTERSON AFB, Ohio - Jet fighter experts at the Boeing Co. will upgrade 71 U.S. Air Force F-15 combat jets with new radar under terms of a half-billion-dollar order.
Officials of the Air Force Life Cycle Management Center at Wright-Patterson Air Force Base in Ohio awarded a $558.5 million contract modification to the Boeing Defense, Space & Security segment in St. Louis to install the upgraded radar systems on Air Force F-15C/D jet fighters and F-15E fighter-bombers.
Boeing, the original manufacturer of the F-15C/D and F-15E combat jets, will install the Raytheon APG-63(V)3 radar on 42 F-15C/D, and Raytheon AN/APG-82 radar systems on 28 F-15E under terms of the contract.
The F-15, designed by McDonnell Douglas, is a twin-engine, all- weather tactical air-superiority jet fighter. It was designed in the late 1960s and entered service in 1976. The F-15E is a ground-attack version that entered service in 1989. The first Air Force F-15E to receive the AN/APG-82 radar upgrade made its inaugural flight in June 2014.
The Raytheon APG-63(V)3 and AN/APG-82 radar systems use active electronically scanned array (AESA) technology, which can steer the radar beam without mechanically moving the radar transceiver antenna. AESA radar uses many solid-state transceivers in an antenna array. It steers the radar beam by emitting separate radio signals from each module. This kind of radar is difficult to detect over background noise and enables F-15 combat jets to broadcast powerful radar signals while still remaining somewhat stealthy.
The Raytheon APG-63(V)3, in service since 2006, is a more modern variant of the company's APG-63(V)2, and applies the same kind of AESA technology that Raytheon uses in the APG-79 designed for the Navy's Boeing F/A-18 Hornet fighter-bomber.
The Raytheon AN/APG-83 radar for the F-15E combines the processor of the APG-79 radar with the antenna of the APG-63(V)3 AESA being on the F-15C/D. This radar upgrade, part of the F-15E Radar Modernization Program, includes a wideband radome for operation on more radar frequencies and improvements to environmental control and electronic warfare (EW) systems.
On this contract Boeing will do the work in St. Louis and should be finished by early 2019.
