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).[1] 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.
