The Shenyang J-31 (or "FC-31 fifth Generation Multi-Purpose Medium Fighter") also known as the "Gyrfalcon"  or "Falcon Hawk" by some military enthusiasts, is a twin-engine, mid-size fifth-generation jet fighter currently under development by Shenyang Aircraft Corporation.

The Lockheed SR-71 was an advanced, long-range, Mach 3 strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12A aircraft by the Lockheed Skunk Works. The SR-71 was unofficially named the Blackbird, and called the Habu by its crews.

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.

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.

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).
