HMS Forth was launched today. It's an offshore patrol vessel.

I look forward to sister ships in due course. HMS COBOL, perhaps. There was Her Majesty's Trawler Algol a while ago, and three warships called HMS Java. HMS Hermes celebrated early network language development before reincarnation as an Indian aircraft carrier, HMS Pascal was sunk by a U-Boat, HMS Perl was listed as defeating Blackbeard in 1718 but I think that's a misprint. There was HMS Python too, renamed Pandora in 1928 because no sailor would go to sea in a ship named after a snake - unlucky women yes, snakes no. HMS Easytrieve, sadly, never existed.

Any I've missed?
