The M5 Stuart light tank made its debut in the invasion of Casablanca in French North Africa. By 1943, and at the time of the invasion of Sicily, the upgraded M5A1 was becoming the standard light tank of the American armored divisions. Because of limited firepower, the M5A1 eventually took on reconnaissance and escort duties in Italy and, after the invasion of Normandy, throughout Europe.

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 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.

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').

The Elefant (Elephant) stemmed from the Porsche design for the PzKpfw VI Tiger. Henschel was awarded the contract for the new tank, but it was decided to use the Porsche design as a tank destroyer. Hitler demanded that the new vehicle be ready for the 1943 offensive on the Russian front, so development was rather hurried.

The Northrop P-61 Black Widow, named for the American spider, was the first operational U.S. military aircraft designed specifically for night interception of opposing aircraft, and was the first aircraft specifically designed to use radar.
