DSRV

One of the USA's two Deep Submergence Rescue Vehicles (DSRVs), the AVALON has been mothballed but its sister the MYSTIC will carry on in service until the new rescue system (Submarine Rescue Diving and Recompression System (SRDRS)) has been proven. A key feature of the current US system is its ability to use a submarine as a MOSUB allowing operations in higher sea states or potentially in the marginal ice zones. It has been tested for use with UK and French SSBNs as well as US SSNs.

'McCann' Diving Bell (SRC). 

This system proved its value when used to rescue 33 survivors from the USS SQUALUS on May 23, 1939.  Today it remains a very simple yet capable rescue system.  

It is also operated by Turkey, and Italy and proved an effective system during both Sorbet Royal 2000 and 2002.  

The USN SRC is air transportable to a VOO MOSHIP which requires little modification to use the system.  

TUP is not possible.

Similar systems may be operated by Russia and  China.

SRDRS

The USN is undergoing a transformation in its capabilities for Submarine Rescue.  By September 2007 the DSRV will have been replaced by the Submarine Rescue Diving and Recompression System (SRDRS).  The future USN system will have a significantly greater capacity than the Australian REMORA and will be fully air transportable to a Vessel Of Opportunity (VOO) MOSHIP.  Transfer Under Pressure (TUP) will be possible up to 5 Bar absolute.

MOSHIP requirements are similar to those for the UKSRS but need a rather smaller deck area.
