The LWT Programme covers In-Service Support (ISS) for the MU90 torpedoes the Participating States currently have in service.

The MU90 Impact is an advanced lightweight anti-submarine torpedo of the 3rd generation developed by France and Italy for navies of France, Italy, Germany, Denmark, Australia and Poland. The MU90 is built by EuroTorp, a consortium of French and Italian companies.

The MU90 is designed to be capable of discriminating between actual and perceived threat, including a bottomed stationary mini-submarine, known versions of anechoic coatings, and various decoys.

It is capable of launch speeds up to 400 knots (740 km/h; 460 mph), allowing it to be dropped from maritime patrol aircraft flying at high speeds, or rocket-assist launchers.

Powered by an electric pump-jet, it can be run at "silent" speeds to avoid giving its location away to the submarine, or "dash" at speeds over 29 knots.
