L3Harris to build electronic warfare (EW) payloads onboard to protect Navy ships from anti-ship missiles

WASHINGTON- Electronic Warfare (EW) experts aboard US Navy ships are asking L3Harris Technologies Inc. to build special EW payloads to help protect Navy warships from enemy anti-ship cruise missiles.

Naval Sea Systems Command officials in Washington on Thursday announced a potential $124 million sole-source contract for the MK 234 series payloads 10/11/12/13 Nulka Advanced Decoy Architecture Program (ADAP).

The ADAP payload provides an advanced EW transmitter and increased signal processing capability to target specific threats that the current payload on the onboard Nulka decoy does not. The initial contract value is $33.6 million.

ADAP payloads are designed to lure missiles away from their targets using advanced electronic techniques. ADAP payloads are an upgrade to the existing Nulka decoy.

Nulka is a joint program with Australia and is in service with the Australian, Canadian and United States navies. Nulka consists of the MK 53 decoy launch system and the MK 234 outboard active decoy to defeat hostile anti-ship missiles.

The MK 53 DLS consists of a decoy launch processor, launch feeds, and two to six launchers depending on ship class. Each caster can store and cast two Nulka decoys. The MK 53 DLS provides launch clearance and flight requests to the Nulka decoy when a Nulka engagement is initiated.

The MK 53 DLS was installed on American Ticonderoga-class cruisers, Arleigh Burke-class destroyers, Nimitz-class aircraft carriers, Whidbey Island-class amphibious assault ships and Harpers Ferry.

On this contract, L3Harris will perform the work of Clifton and Hamilton, NJ; Rancho Cordova, California; Ronkonkoma, NY; and Andover, Mass., and is expected to be completed by April 2026.
