In 1928, the rear of the tank was modified to strengthen it. [3] At the same time, a new design of brake-block was fitted. [3] The transmission was also heavily reworked. [5] The tank was the subject of industrial and political espionage, the plans ending up in the Soviet Union, where they may have influenced the design of the T-28 and T-35 tanks.
The VK 45.02 (P) was the official designation for an unsuccessful heavy tank project designed by Ferdinand Porsche in Nazi Germany during World War II to compete with Henschel's design. [1] Development of this vehicle started in April 1942, with two design variants (Ausf. A and Ausf. B) incorporating different features.
Fpl 35-5 was the first aircraft built to Saab 35A-series specifications. It featured an original Rolls-Royce Avon Mk.48A (RM6BE) engine and had the same afterburner and tail as the J 35A1 (Adam short) variant. Later it was modified to Saab 35D standard and acted as the Saab 35H demonstrator during the Swiss trials. [22] Fpl 35-6
The company was founded in 1892 by two graduates of Iowa State College, William H. Jackson and Berkeley M. Moss. [8] The partners initially contracted to have their steel tanks fabricated by Keystone Bridge Company of Pittsburgh, but soon took on a third partner, Edward W. Crellin, who was operating a small fabricating shop in Des Moines, Iowa.
Design specifications for the VK 70.01 project changed throughout its developmental history. Primary armament would’ve been either a 105, 128, or 150 mm gun, while armour ranged from 100–120 mm (3.9–4.7 in) frontally and 80–100 mm (3.1–3.9 in) on the sides.
The Tortoise heavy assault tank (A39) was a British heavy assault gun tank design developed during the Second World War, but never put into mass production. It was developed for the task of clearing heavily fortified areas such as the Siegfried Line and as a result favoured armour protection over mobility.
The remaining tanks, that is the ones used for training as well as tanks that were finished after the outbreak of the war, were used in an improvised tank unit fighting in the defence of Warsaw. Although technically superior to any of the German light tanks of the era, the 7TP was too scarce to change the outcome of the war.
The A13 specification was produced prior to the second world war, calling for the development of a new cruiser tank. This was the first specification of British cruiser tank to be based on the Christie suspension design. The specification was revised over time, and lead to the development of three different vehicles: [1]
