TheLR7 is adeep-submergence rescue vehicle (DSRV) of thePeople's Republic of China'sPeople's Liberation Army Navy (PLAN). It was built by FET (Forum Energy Technologies) formerly Perry Slingsby ofBritain. The LR7 entered service in 2009.[2]
In 2000 and 2001, Chinese representatives attended international submarine rescue conferences and exercises. This may have followed the 1995 accident suffered byChinese submarine361 while surfaced leading to the deaths of the entire crew. China entered negotiations to purchase DSRVs from Britain orCanada[4] which may have resulted in the order for the LR7 throughRolls-Royce Marine.[3]
The LR7 was tested inLoch Linnhe,Scotland, in September 2008. It was delivered[3] and entered service in 2009.[2]
TheType 926 submarine support ship was developed to deploy the LR7. The first was laid down in 2007 and entered service in 2010.[5]
The LR7 may operate at depths of 500 meters and may dock with submarines with their bows 60 degrees up.[2]
