The Typhoon was a British single-seat strike fighter, produced by Hawker Aviation starting in 1941. Intended as a replacement for the Hawker Hurricane in the interceptor role, it suffered from performance problems, but eventually evolved into one of World War II's most successful ground attack aircraft.

During the late 1960's a number of European countries examined ways to replace their existing fleet of combat aircraft using next-generation design techniques. Several countries looked at variable geometry wing configurations as a means of making a plane perform well throughout a wider flight envelope.

The Infantry Tank Mark II, best known as the Matilda, was a British infantry tank of the Second World War. The design began as the A12 specification in 1936, as a gun-armed counterpart to the first British infantry tank, the machine gun armed, two-man A11 Infantry Tank Mark I.

The Char B1 had its origins in the concept of a Char de Bataille conceived by General Jean-Baptiste Eugene Estienne in the twenties. On January 27th, 1926 it was decided to build three prototypes of a Char B, based on four earlier experimental vehicles (a FAMH-model, the FCM 21, the SRA and the SRB).

Numerically the most abundant fighter produced by either side during WWII, the Messerschmitt Bf 109 formed the backbone of the Jagdwaffe on both the eastern and western fronts, as well as in the Mediterranean and North Africa. Of the eight distinct sub-types within the huge Bf 109 family, the most populous was the G-model, of which over 30,000 were built between 1941-45.
