This is realistic.
Lancasters, Halifaxes and Short Sterlings where all modifies to
drop lifeboats down to stranded crew.
Dropping battleships in the same way would be much easier
because it is far easier to drop a heavy thing like a battleship
than it is to drop a light thing like a lifeboat.
Heavy things are just easier to drop because gravity drags them down more.
