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. By 1990, both AAWWS and MSIP were renamed Longbow. The radar is produced by Longbow LLC, a joint venture of Lockheed Martin and Northrop Grumman. In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/APG-78" designation represents the 78th design of an Army-Navy airborne electronic device for radar fire-control equipment. The JETDS system also now is used to name all Department of Defense electronic systems.
