Mitchel Air Force Base, also known as Mitchel Field, was a United States Air Force base located on the Hempstead Plains of Long Island, New York, United States.Established in 1918 as Hazelhurst Aviation Field #2, the facility was renamed later that year as Mitchel Field in honor of former New York City Mayor John Purroy Mitchel, who was killed while training for the Air Service in Louisiana.
The AN/TPY-4, formerly known as the TPY-X, is a ground-based, active electronically scanned array, L-band, multi-function long-range 3D radar for air defense surveillance, built by Lockheed Martin. [2] It is a radar capable of multi-mission operation, and perform simultaneously the following work: air surveillance; low profile UAS detection
In 2019, the U.S. Army selected Lockheed Martin to develop the active electronically scanned array (AESA) variant of the radar in a $281 million contract. [5] The Sentinel A4 is a complete redesign of the sensor that uses digital processing and solid-state antenna modules based on gallium nitride (GAN) transmitters.
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. [1] [2] The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.
The AN/APG-78 Longbow is a millimeter-wave fire-control radar (FCR) system for the AH-64D/E Apache attack helicopter. It was initially developed in the 1980s as the Airborne Adverse Weather Weapon System (AAWWS) as part of the Multi-Stage Improvement Program (MSIP) to enhance the AH-64A. [2] By 1990, both AAWWS and MSIP were renamed Longbow. [3]
The AN/SPY-1 [a] is a United States Navy passive electronically scanned array (PESA) 3D radar system manufactured by Lockheed Martin, and is a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage.
While Lockheed Martin is the prime contractor for the 420K aerostats, the envelopes are built by ILC Dover. As of 2004, all TARS sites except one were equipped with the 420K aerostats. The exception is Cudjoe Key , which uses two smaller, but otherwise similar, Lockheed Martin 275K blimps.
The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.
