Stuka Ju-87
The Junkers Ju 87 (or more commonly known as the Stuka dive-bomber, an anglicised abbreviation for "Sturzkampfbomber") is an airplane used on Earth, by Germany, during World War II.
The plane was commonly used by German Luftwaffe in bombing campaigns in Poland and England. They fired 7.9mm rounds and were equipped with sirens located on the wheel covers to frighten the enemy on the ground during dives from high altitudes.
When Enterprise was trapped in an alternate timeline in 1944, the ship entered Earth's atmosphere to destroy a temporal conduit that the Na'kuhl were constructing. Their leader, Vosk, dispatched a squadron of Stukas refitted with plasma cannons to destroy the ship. (ENT: "Storm Front, Part II")
