The 155 K 83
is a Finnish
towed 155 mm field gun, 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 and were never part of the war-time inventory. 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 M68 and the South African G4.
The gun was modified in the late 1990s, for instance given a longer, 52 calibre barrel and an auxiliary power unit. This gun is called 155 GH 52 APU (or 155 K 98 in Finnish Army service).
