The FTAS is the Ground Combat Element’s indirect fire acquisition capability. The FTAS comprises the TPQ-46 Fire-finder Ground Weapons Locating Radar (GWLR), the TPQ-48 Lightweight Counter Mortar Radar (LCMR), and the TSQ-267 Target Processing Set (TPS).
The AN/TPQ-46 Fire-finder provides the ability to locate indirect-fire (IDF) weapons – which include mortars, artillery, and rockets – within a 1600 mil search sector from ranges of .75 to 24 kilometers. It is the primary IDF detection system in the Marine Corps.
The AN/TPQ-49 LCMR provides a 6400 mil mortar detection capability at ranges of 1 to 5 kilometers, short-range detection coverage, and slewing/cueing intelligence to the AN/TPQ-46 via the AN/TSQ-267.
The AN/TSQ-267 TPS is the command and control (C2) node of the FTAS capability providing radar deployment orders, support functions and target data to the counter-fire/countermeasure-servicing agent. The TPS uses the Advanced Field Artillery Tactical Data Systems (AFATDS) as its primary communication and C2 tool.
The FTAS Program Office is supporting the warfighter with all three systems. The CMR is currently deployed to Afghanistan to support Operation Enduring Freedom (OEF). The Marine Corps recently reduced the Approved Acquisition Objective (AAO) for the Fire-finder and the LCMR.
The Fire-finder was reduced from 44 to 28 systems and the LCMR was reduced from 46 to 42 systems. The AAO for the TPS is seven sets, two for each active-duty artillery regiment and one for the reserve component. Full Operational Capability (FOC) for the TPS was achieved in September 2011. The FTAS achieved FOC on 17 December 2015.
