Common Weapon Launcher (CWL)

The Common Weapon Launcher (CWL) is the next generation weapons launch system for the U.S. and Australian (RAN) Navy submarines. CWL processes and transmits/receives weapon information during all launch phases for U.S. Navy Virginia and Columbia-class submarines, as well as RAN Collins-class submarines. CWL employs intuitive, user-friendly screens to manage, monitor, and launch various tube-loaded weapons and payloads while providing onboard training, weapon simulation and much more.

Multi-Tube Weapon Simulator (MTWS)

Multi-Tube Weapon Simulator (MTWS) provides robust simulation capability for emulating weapon behavior during pre-launch, launch, and post-launch phases of torpedo tube launched weapons for U.S. and allied submarines. MTWS simulated weapon capabilities support high fidelity combat system testing and troubleshooting as well as flexible, realistic crew training for all torpedo tube launched weapons.
