I am reposting one from military aviation to emphasize the research on how to determine markings and ordinance. I can't help but think non naval units would designate torpedo units as opposed to level bombing units. I would include anti-submarine units as well as units that launched rockets or had extra machine guns and cannons used for strafing. I suppose in the past I always went with what the governments said about their aircraft. In some cases it is obvious that the Mosquito was a bomber and a fighter in different marks. The P-61 Black Widow, big as it was was a fighter.a SM-79 Sparviero seems to have mostly dropped torpedoes as did the Bristol Beaufort. It gets complicated by one country who had a type may have used it for torpedoes, another may have made a night fighter.French planes of the Potez type have me stumped. Basically I am asking help in sorting these types into their various missions, I mean primary use, not secondary use as a transport unless relegated to that role. I believe it is a give that the Japanese used almost anything as a Kamikaze. In fact it would fill out the picture if any types such as a Frances or Irving were too valuable to use as kamikazes. Also I know in the case of Dorniers and Junkers twin engine types they served in distinctly different units such as level bombing and night fighter.
I think I read that the B-26 Marauder could launch torpedoes. This is just one example of a multi role plane It causes me to wonder if this and other twin and three engine types had different nits and crews for different missions. I would think the answer is yes. Then I wonder about distinct codes and unit insignia place on a regular paint job for a given air force. How could one tell a B-26 that trained to launch torpedoes. I believe He-111s launched torpedoes. I suppose the number of multi-use types is bigger than I suppose.
