MSM-1 USEL (Unità di Soccorso E Lavoro - Rescue and Work Vessel) was a deep-submergence rescue vehicle (DSRV) that was rated to dive up to 600 m (1,969 ft).[1] It was built by Cantieri Navali Ernesto Breda/Fincantieri for the Marina Militare. The sub was capable of descending to 600 metres (2,000 ft) below the surface and could carry 8 passengers at a time in addition to her crew. MSM-1 USEL was hosted by mother ship Anteo at La Spezia from 1980 to 2002. That year MSM-1 USEL was replaced by the DRASS Galeazzi SRV-300.
