The PBY Catalina was the US Navy designation for an American and Canadian-built flying boat of the 1930s and 1940s. PB stands for Patrol Bomber, with Y being Consolidated's manufacturer identification. It could be equipped with depth charges, bombs, torpedoes, and .50 caliber machine guns and was one of the most widely used multi-role aircraft of World War II.

The AV-8B Harrier II is a second generation vertical short takeoff and landing (V/STOL) aircraft based on the original British Harrier design of the late 1960's. Combining tactical mobility, responsiveness, reduced operating cost, and basing flexibility -- both afloat and ashore -- V/STOL aircraft are well-suited to the special combat and expeditionary requirements of the US Marine Corps.

The German Waffenamt issued an order to design the VK4501(H) (as the PzKpfw VI Ausf. E was then known) in May 1941, just one month prior to the commencement of Operation Barbarossa. Interestingly, Henschel und Sohn of Kassel was charged with building the heavily armored chassis while Krupp, by far the largest munitionwerks in Germany, was given the task of developing the turret.

The Albatros D.V was a German fighter airplane used during World War I. In April 1917, Albatros received an order from the Idflieg (Inspektion der Fliegertruppen) for an improved version of the D.III.

Developed as a private venture by the Bristol Aeroplane Company, the Beaufighter was a two-seat all-metal fighter using components from the Beaufort torpedo-bomber. First flown on July 17th, 1939, the Beaufighter eventually equipped 52 RAF squadrons, giving outstanding service during World War II, in particular as a night-fighter and torpedo-bomber (where the aircraft were affectionally known as 'Torbeaus').

Early in 1943, orders were given to design a heavy, self-propelled anti-tank gun, which would mate a 12.8cm gun with a Tiger II chassis. On October 20th, 1943 a wooden mock-up of the enormous vehicle was shown to the OKH planners who authorized that a prototype be finished by April 1944.
