The US Navy (USN) is pushing ahead with plans to field the High Altitude Anti-Submarine Warfare Weapon Capability (HAAWC) on the Boeing P-8A Poseidon maritime multimission aircraft (MMA), despite recent comments made to the contrary by some senior service officials.

The aircraft original equipment manufacturer (OEM) is to be awarded a sole-source contract for full-rate production (FRP) of the HAAWC Air Launch Accessory (ALA) for use in launching the Mk 54 torpedo from the Poseidon MMA from high altitude.

This notification released by the Department of the Navy on 8 June follows a March 2017 decision by the USN Commander Patrol and Reconnaissance Group (CPRG) to withdraw its endorsement of the high-altitude anti-submarine warfare (ASW) capability.

As noted in the navy’s solicitation, “The primary HAAWC capability requirement is to increase the stand-off range and weapon release altitude for the P-8A Poseidon aircraft during ASW missions for employment of a lightweight torpedo against submarine targets.
