During my search for my post above I came across another piece of information that I think definitely fits into the "odd" part of our military facts.
The USS Density (AM-218) served the USN in the Pacific theatre as an ocean-going minesweeper. She was placed in the reserve fleet in Galveston, Texas in January 1946 and was decommissioned there in March 1947.
Like so many other WW2 ships, being released from naval service didn't end her career.
She was sold to Greek interests as a cargo ship in 1955 and renamed the MV Manoula. In 1964 she was impounded in Miami, Florida for non-payment of harbour fees but later that same year she was bought by other interests and renamed MV Galaxy.
In November 1964 she arrived in British waters were she began broadcasting as Radio London - one of the pirate radio stations operated outside territorial waters to, so it's claimed, circumvent the record companies' control of popular music broadcasting in the United Kingdom and the BBC's radio broadcasting monopoly.
When the pirate radio stations were closed down by the British government in 1967, MV Galaxy sailed for Germany. She tied up in Hamburg harbour in anticipation of another stint as an offshore radio station.
The deal fell through and MV Galaxy was transferred to Kiel harbour and sunk as an artificial reef in 1979. Concerns about pollution saw her raised from the harbour floor for breaking up/disposal in 1980.
So MV Galaxy, the former MV Manoula, former USS Density, a combat-tried ocean-going minesweeper built for the USN during WW2 (with several successful engagements against the Japanese), ended her days tied up to the Kilian bunker, a former Kriegsmarine U-boat base.
