Depth Capabilities of subs/uboats

[Ducimus]

Airborne depth charges seem to have always been set for 25 feet (roughly 8 metres).

Tater kicked up an interregation report online somewhere, where the Japanese pilot said they carried two charges, one set at 20 meters, the other at 45. They'd drop one or the other depending on where they thought the boat was. Wish i could provide the link, i do recall reading it, but this was probably close to a year ago, so id be hard pressed to find that reference material now.
