Sunderland and torpedos
Torpedos were certainly not routinely carried. The only reference I can find is to experiments carried out at the MAEE at Helensburgh as part of the run up to attacks on the Tirpitz.
Bombs, mines, depth charges could be run out on carriers from the “bomb room” under the wing centre section. Four stations per side. IIRC the carriers were winched out by hand. I don’t remember that it was possible to rearm the carriers in flight using any stores kept in the bomb room, but I think not.
Slightly dim memories of a tour conducted for me by my father, ex 209/205.
