San Diego ? Do you have space for a sub?

The Navy is looking to give away its vintage, one-of-a-kind USS Dolphin, a research vessel commissioned in 1968. The service said in a Federal Register posting it will accept offers from government agencies, nonprofit groups or other institutions willing to make the submarine into a museum.

The Navy hopes to keep the vessel in its home port of San Diego. Any new owner, who must submit offers by March, also will be required to keep the 165-foot sub in good condition.

It’s not the first sub to be given away. Navy spokeswoman Pat Dolan said the first vessel given away was in 1945, when it gave the battleship Texas, a dreadnought that fought in both World Wars, to a state historic site near Houston. At least 47 other boats have been donated.
