The MU90 Impact is an advanced lightweight anti-submarine torpedo of the 3rd generation[3] developed by France and Italy for navies of France, Italy, Germany, Denmark, Australia and Poland. It is designed to compete with and outperform the United States-built Mark 54 in the anti-submarine role, and has also been developed in a special MU90 Hard Kill version for torpedo anti-torpedo defence.[2] The MU90 is built by EuroTorp, a consortium of French and Italian companies.
