Hi All, hope my entry makes it, Below is the closest reference I can find to TMs being used in Naval operations during WWII. With the added weaponry it does not seem unlikely that it was used to attack naval vessels though. "As well as its primary duties as a trainer, the Tiger Moth was used in a variety of different roles during the war. It served as a communications and utility aircraft, wireless (radio) trainer, artillery spotter, air ambulance and for prisoner evacuation. The threat of a German invasion of Britain led to a number of Tiger Moths being converted to a defensive and offensive role. Bomb racks capable of carrying eight 25 lb bombs were developed to be fitted under either the wings or fuselage of the aircraft. Others were tasked with anti submarine duties after five Tiger Moth coastal patrol units were formed in 1939. Flying in pairs, the aircraft would record shipping movements and look for German U-boats. If one was spotted, the Tiger Moths would drop flares in the area and then wait for naval forces to arrive. When no naval forces were available, it was hoped that the mere presence of an aircraft near a U-boat might deter its commander from running on the surface, reducing his ability to attack shipping. There were also some rather bizarre anti-invasion ideas trialled such as the "Paraslasher", an 18-inch farmer's hand-scythe attached to an 8 ft pole below the Tiger Moth's fuselage. The theory was that the aircraft would fly among invading paratroopers, slicing up parachute canopies, shroud lines and the occasional paratrooper before further harassing those that made it to the ground. Another idea was to install a chute in the cockpit floor so hand grenades could be dropped on enemy soldiers. Although this looked good in theory, pilots voiced concerns over the consequences of a live grenade jamming in the chute and the project was quickly abandoned."
