Lockheed Martin to refurbish M-TADS/PNVS electro-optical sensors aboard Army AH-64 Apache attack helicopters

The Arrowhead targeting sensor suite has forward looking infrared (FLIR) elements of the TADS and the PNVS to provide precision engagement.

REDSTONE ARSENAL, Ala. – U.S. Army aviation experts needed a company to refurbish electro-optical assemblies in the Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor (M-TADS/PNVS) system, also known as Arrowhead. They found their solution from Lockheed Martin Corp.

Officials of the Army Contracting Command at Redstone Arsenal, Ala., announced a $13.1 million order Monday to the Lockheed Martin Missiles and Fire Control segment in Orlando, Fla., for a M-TADS/PNVS for a refurbishment support effort on the AH-64 Apache attack helicopter.

The lower M-TADS turret contains the targeting system, which has day and night electro-optical sensors. The Arrowhead targeting sensor suite has forward looking infrared (FLIR) elements of the TADS and the PNVS to provide modern technological and precision engagement, and ensure the Army’s Apache helicopter remains an effective attack helicopter well into the future.

The system's laser rangefinder designator includes an eye-safe rangefinder and day sensor electronics unit, which replace the laser transceiver unit and related electronics in the Apache’s legacy day sensor assembly.

The new day sensor structure assembly offers fields of view that match the Arrowhead FLIR fields of view to accommodate image blending. The modernized TV sensor incorporates color and low-light sensitivity. A modern inertial measurement unit replaces three spinning-mass gyros, and the new laser spot tracker uses a four-quadrant detector and improved processing. A laser pointer marker helps enhance coordination with ground and air units.

These targeting components enable Apache helicopters to identify targets at long ranges through an additional field-of-view and extended-range picture-in-picture capability, as well as provide the ability to view high-resolution, near-infrared and color imagery on cockpit displays.

The system provides a new laser pointer marker that improves coordination with ground troops, and an updated multimode laser with eye-safe lasing capability that supports flight in urban environments and home-station training.

M-TADS/PNVS provides Apache helicopter pilots with long-range, precision engagement and pilotage capabilities for mission success and flight safety during day and night and in adverse weather conditions.

On this order Lockheed Martin will do the work in Orlando, Fla., and should be finished by August 2025.
