The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is currently being developed by Northrop Grumman and is expected to reach initial operating capability in August 2016. The Ground/Air Task Oriented Radar (G/ATOR) is a single materiel solution for the mobile Multi-Role Radar System and Ground Weapons Locating Radar (GWLR) requirements. It is a three-dimensional, short/medium range multi-role radar designed to detect unmanned aerial systems, cruise missiles, air breathing targets, rockets, artillery, and mortars. G/ATOR satisfies the warfighter’s expeditionary needs across the Marine Air-Ground Task Force spectrum replacing five legacy radar systems with a single solution. The five Marine Corps legacy radar systems being replaced by this multi-function capability include: the AN/TPS-63 (air defense), AN/TPS-73 (air-traffic control), AN/MPQ-62 (short range air defense), AN/TPQ-46 (counter-fire target acquisition) and UPS-3 (target tracking). Additionally, it will augment the AN/TPS-59 long-range radar. The Program Executive Office (PEO), Land Systems Marine Corps is executing the G/ATOR program as an evolutionary acquisition program consisting of four capabilities, referred to as blocks.
