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.

Built by North American, with no previous experience on multi-engined aircraft, the B-25 Mitchell proved to be one of the most versatile combat aircraft to see action in World War II. So impressed with what they saw on the drawing board, the USAAC ordered 184 aircraft -- to be designated the B-25 -- before metal had even been cut on a revised design.

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.

Design on the KV-1 heavy tank began in 1938, with the intention that it should be the successor to the T-35 heavy tank. The first models of the KV-1 were field-tested during the Red Army's disastrous 1940 campaign in Finland.

Nicknamed the "Jug" for its bulky shape, the Republic P-47 Thunderbolt was considered a monster of a machine. Despite its size, the Thunderbolt proved to be a fast and maneuverable warbird able to hold its own in combat. In fact, when Allied pilots climbed aboard a P-47, they knew the were in control of a fighting machine with enormous power.

The Hawker Hurricane was the first monoplane to join the Royal Air Force as a fighter aircraft, capable of reaching speeds in excess of 300-mph in level flight. Often compared with the sleek-looking Supermarine Spitfire, the Hurricane, in actuality, shouldered the brunt of the fighting during the "Battle of Britain", equipping more than three-fifths of the RAF's Fighter Command squadrons.
