It was the scourge of World War II and no other aircraft terrorized its victims as much as the Junkers Ju 87 Stuka.It made its combat debut with the Condor Legion during the Spanish Civil War and was extremely accurate against ground targets. For the German commanders, the Stuka was their flying artillery. It was instantly recognizable with its inverted gull wings, fixed spatted undercarriage and infamous Jericho-Trompete ("Jericho Trumpet") wailing siren, a psychological weapon used to terrify ground troops.
