HMS Grenade
From Tardis Wiki, the free Doctor Who reference
The HMS Grenade was a Royal Navy vessel during World War II, which was sunk by German forces at the Battle of Dunkirk on 29 May 1940. The Eighth Doctor and Molly O'Sullivan accidentally landed the TARDIS on the HMS Grenade on this day, and when the ship sank the TARDIS sank with it. (AUDIO: Fugitives)
