The Tampella 155 K 83 is a Finnish towed 155 mm field gun (Finnish designation; technically it is a gun-howitzer), manufactured in the 1980s by Tampella.



The development process for the 155 K 83 began in 1960 when Tampella presented their concept of a new 122 mm gun for the Finnish Army. It was a sound concept, but quite a heavy gun. It was only ordered in small numbers. In order to take advantage of the design, a decision was made to further develop this into a 155 mm gun. Through a number of development stages the 155 K 83 was born.

The drawings were also used to develop the Israeli Soltam M-68, which, after improvements, became the Soltam M-71 (designated the G4 in South Africa). [2] Some guns have been modernized to 155 K 83-97 standard.

The gun design was further modified in the late 1990s. The gun, called 155 GH 52 APU (or 155 K 98 in Finnish Army service), was given a longer, 52 calibre barrel and an auxiliary power unit, enabling it to move by its own power. The chamber was also changed to support modern NATO-standard charge bags.

Infantry tank Armoured fighting vehicle

The infantry tank was a concept developed by the United Kingdom and France in the years leading up to World War II. Infantry tanks were designed to support infantrymen in an attack. To achieve this, the vehicles were generally heavily armoured to allow them to operate in close concert with infantry even under heavy fire. The extra armour came at the expense of speed, which was not an issue when supporting relatively slow-moving foot soldiers.

Bofors 75 mm Model 1929 Type of Anti-aircraft gun

Bofors 75 mm and Bofors 80 mm were two closely related designs of anti-aircraft and general-purpose artillery. Less well known than the 40 mm quick-firing AA gun, the gun was nevertheless adopted by armed forces of numerous countries during World War II, including Argentina, China, Dutch East Indies, Finland, Greece, Hungary, Persia and Thailand. It was closely related to the 8.8 cm Flak 18/36/37/41, one of the best-known AA guns of World War II, which was partially based on it. Some pieces captured by the Japanese in China served as the blueprint for the Type 4 75 mm AA Gun, a reverse-engineered clone of the Bofors 75mm gun.
