SRV-300 is a deep-submergence rescue vehicle that is rated to dive up to 300 m (980 ft).[1] It was built by DRASS (Livorno) for the Marina Militare, and is capable of descending to 300 metres (980 ft) carrying 12 passengers in addition to crew. SRV-300 is hosted by Anteo, berthed at La Spezia.
SRV-300 supplanted the Breda MSM-1S USEL deep-submergence rescue vehicle, in 2002 and since 2004 it has been fitted with a Simrad EM-1002 multibeam echo-sounder.[2][3] Further upgrades in 2010 introduced air portability.[4]
There is a new version under development, the SRV-650, with a maximum depth of 650 m (2 133 ft) and with a hosting capacity of 15 people.
