The MU90 Impact is a Franco-Italian advanced lightweight anti-submarine torpedo of the third generation[3] developed for the French and Italian navies, as well as for export.

It is designed to outperform the United States-built Mark 54 in and was developed in a special MU90 Hard Kill version for anti-torpedo defence.

In France, a project under the direction of Thomson Sintra created the "Murène" in 1989, while in Italy Whitehead started work on an A244 replacement known as the A290.

[1] 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.

France dropped out of the programme but Italy has fitted the MBDA MILAS missile to its Durand de la Penne-class destroyers and FREMM anti-submarine frigates.
