Navy continues project to install submarine-hunting radar aboard MH-60R helicopter fleet

PATUXENT RIVER NAS, Md. – U.S. Navy anti-submarine warfare (ASW) experts are moving forward with a project to upgrade the Navy MH-60R ASW helicopter fleet with a special submarine-huntingradar system designed to detect and classify submarine periscopes as they pop briefly out of the water.

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station announced a $45.8 million order Monday to Lockheed Martin Corp. Rotary and Mission Systems Segment in Owego, N.Y., which manufacturers the MH-60R helicopter, to install 29 AN/APS-153(V)1 automatic radar periscope detection and discrimination multi-mode radar kits in MH-60R helicopters.

The APS-153 radar, designed by Telephonics Corp. in Farmingdale, N.Y., is rugged, lightweight, has low-prime power, offers extremely small target detection, high-resolution imaging, and long-range surface search.

Monday's contract modification to Lockheed Martin is an order against a $67.6 million contract last July for the company to provide as many as 103 AN/APS-153(V)1 automatic radar periscope detection and discrimination multi-mode radar kits to upgrade the MH-60R fleet.

Telephonics engineers designed and developed the AN/APS-153(V) for the rugged maritime operating environment of Navy MH-60R helicopter, which the Navy uses for ASW; anti-surface warfare; command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR); surface surveillance; maritime interdiction; combat search and rescue; medical evacuation; logistical support; identification friend or foe; battle damage assessment; naval surface fire support; and imaging.

The AN/APS-153(V) provides the MH-60R and its host ship with persistent littoral and maritime domain awareness. It enables operators to classify detected moving ship targets under night and restricted visibility using its high-resolution inverse synthetic aperture radar (ISAR) mode.

ISAR enables the MH-60R to operate outside of visual and lethal range of a potential enemy and to identify detected targets when images are combined with other intelligence.

The MH-60R controls the AN/APS-153(V radar through the helicopter's mission computer with returns shown on 8-by-10-inch color multi-function displays. The Lockheed Martin Corp. Mission Systems and Training segment in Owego, N.Y., integrates the AN/APS-153(V) into the MH-60R avionics suite.

The AN/APS-153(V) weapons replacement assembly integrates an IFF interrogator, which provides Mark XII IFF modes 1, 2, 3A and 4 to identify friendly IFF-equipped aircraft, surface ships, and submarines.

The MH-60R helicopter can send visual information from the AN/APS-153(V) to its host ship via the helicopter's C-band data link. Future upgrades to the radar may include capabilities like low probability of intercept; ISAR automatic classification aids; synthetic aperture radar; Mode 5/Mode S IFF; and weather.

On this contract Lockheed Martin will do the work of integrating the AN/APS-153(V) onto the MH-60R helicopter in Farmingdale, Owego, and Syracuse, N.Y., and Oldsmar, Fla., and should be finished by September 2020.
