The Junkers Ju 87, commonly known as the Stuka (short for Sturzkampfflugzeug), was a pioneering German dive bomber and ground-attack aircraft used throughout WWII. Known for its inverted gull wings, fixed landing gear, and terror-inducing "Jericho Trumpet" sirens, the Ju 87 was pivotal in early Blitzkrieg operations, including the invasions of Poland, France, and the Soviet Union.
