The M6 was an outgrowth of a 1940 U.S. Army Ordnance Corps program to develop a 50-ton heavy tank. After the initial, multi-turreted design proved too excessive, a single three-man turret bearing 76.2mm and 37mm guns was adopted. The tank also carried four Browning machineguns, three fixed and one flexible. In addition to the commander, gunner and loader in the turret, the tank had a driver, assistant driver, and an ammunition passer. The tank...

Designed by Swedish cryptographer Boris Hagelin, the M-209 Converter was a portable, mechanical cipher machine. Used extensively during WWII and the Korean conflict by both the Army Signal Corps and the U.S. Navy (which designated it the CSP-1500), Hagelin's device allowed a rapid and secure means of communication. The lunchbox-sized machine was so simple that little training was required to use it, yet its cipher scheme proved very difficult ...

The 155-mm Howitzer M1 was first produced in 1942 as a medium artillery piece. It saw service with the US Army during World War II, the Korean War, and the Vietnam War, before being replaced by the M198 Howitzer. The gun was used by the armed forces of many nations, and in some countries, it still remains in service. The 155-mm Howitzer was developed as an afterthought. A new carriage was under development for much of the 1930s for the existin...

Built with twin, underwing engines, tricycle landing gear and shoulder-mounted wings, the Grumman F7F Tigercat was an unusual looking, all-metal fighter. It was also one of the highest- performance piston-engined fighters of all time.Originally designed as a carrier-based aircraft, the F7F failed its initial trials, and ended up flying primarily as a land-based attack aircraft for the Marines. Equipped with radar and a second seat for an opera...

Founded in Scranton, Pennsylvania in 1856, the Dickson Manufacturing Company built steam engines, boilers, hoisting and blowing engines and coal-fired steam locomotives for nearly five decades. The locomotives included 10-wheeled engines for the Santa Fe and 8-wheeled passenger engines for the Delaware and Hudson. While most Dickson engines were standard in terms of engineering, the company was a pioneer in the area of compressed-air locomotiv...

The M18 Hellcat was an American tank destroyer during World War II. Armed with a 76-mm cannon, it was the fastest tracked armored fighting vehicle during World War II with a top speed up to sixty mph. As a result, Buick nicknamed it the Hellcat. The fast speed was reached by keeping armor thickness to a minimum. Hellcat crews took advantage of the vehicle's speed to minimize the enemy's ability to pierce its thin armor.The M18's new design inc...
