Last year, as part of the Yellow Moray program, the USS Delaware, a Virginia-class attack submarine, successfully deployed and recovered a Remus 620 unmanned underwater vehicle (UUV) through its torpedo tube during a mission in support of the United States European Command (US EUCOM). This capability significantly extends the operational range of missions.

For the first time, a French Navy attack submarine has launched and recovered an American Razorback underwater drone.
