Lightweight Torpedo Development

The Lightweight Torpedo Development program, managed by the Navy, focuses on enhancing the MK 54 Lightweight Torpedo (LWT) through hardware and software upgrades. Key areas of improvement include the torpedo's array, warhead, propulsion, and Advanced Processor Build (APB) software. These enhancements aim to address capability gaps against advanced adversary submarines. Additionally, the program seeks to develop enhanced weapon delivery methods, such as high-altitude launches from P-8A Maritime Patrol and Reconnaissance Aircraft using the High Altitude Anti-Submarine Warfare Weapon Capability (HAAWC).

The HAAWC development initiative is designed to enable the P-8A aircraft to deploy MK 54 torpedoes from high altitudes, thereby enhancing their operational range and precision. Current efforts focus on making HAAWC compatible with the MK 54 MOD 2 variant. This involves developing a new design that aligns with the delivery schedule of the MK 54 MOD 2 fleet and exploring a common design for all MK 54 modifications. The program has already achieved Initial Operating Capability for earlier versions and is now concentrating on further development and testing.

The Lightweight Hybrid Torpedo project aims to integrate advanced processor builds and technical insertions to improve performance in challenging environments. The project includes two increments: Increment 1 involves hardware updates and APB 5 software, while Increment 2 focuses on APB 6 software enhancements. These efforts are intended to replace older models with improved versions that offer better performance in littoral waters and against countermeasures.

The Advanced Anti-Submarine Lightweight Torpedo project seeks to enhance lethality and speed by upgrading warhead and propulsion systems. It employs an incremental approach, initially focusing on guidance, control, and warhead development integrated with existing propulsion systems. Future phases will complete these developments and integrate additional capabilities defined by the Capability Development Document. The program plans competitive awards for continued development, ensuring that each increment meets specific operational requirements before moving into production phases.
