The Ground/Air Task Oriented Radar (G/ATOR) is a single material solution for the mobile Multi-Role Radar System and Ground Weapons Locating Radar (GWLR) requirements. It is a
three-dimensional, medium/long-range multi-role radar designed to detect
unmanned aerial systems,
cruise missiles, air-breathing targets,
rockets,
artillery, and
mortars. G/ATOR is designed to fulfil 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 of four capabilities, referred to as blocks. • Block 1 completes the primary material system acquisition, and can support the short-range air defense and air surveillance mission, as well as provide an Air Defence/Surveillance Radar (AD/SR) capability to the MAGTF Commander. • Block 2 includes software to perform the missions of ground counter-battery/fire control (Ground Locating Weapons Radar). • Block 3 capabilities are not currently defined or resourced, and have been deferred indefinitely. • Block 4 provides air traffic control capabilities (Expeditionary Airport Surveillance Radar). G/ATOR provides real-time radar measurement data to the Tactical Air Operations Module, Common Aviation Command and Control System (CAC2S), Composite Tracking Network, and
Advanced Field Artillery Tactical Data System. The G/ATOR baseline system configuration consists of three subsystems: • Communications Equipment Group (CEG). The CEG provides the ability to communicate with and control the radar and is mounted on a
High Mobility Multi-purpose Wheeled Vehicle. • Radar Equipment Group (REG). The REG consists of a phased-array radar mounted on an integrated trailer. The trailer is towed by the
Medium Tactical Vehicle Replacement (MTVR). • Power Equipment Group (PEG). The PEG includes a 60-kilowatt generator and associated power cables mounted on a pallet. The generator pallet is carried by the MTVR. ==Development==
