Introduction

The M-83 is a late Cold War era towed howitzer of Finnish origin. It was developed by Tampella in the 1970's and is based on the earlier Tampella 122 K 60. The Israeli Soltam M-68 and M-71 are a similar development of the 122 K 60 design.

Layout

The M-83 uses a 155mm 39-caliber ordnance with single baffle muzzle brake. The four wheel split trail carriage hinges at the cradle. In the firing position the M-83 rests on a turntable baseplate. In travel configuration the ordnance is rotated rearwards over the trails. The FH-70 is crewed by 8 men. There is no gun shield.

Firepower

The M-83 fires NATO standard 155mm shells. The maximum range is 23 km with standard ammunition and 30 km with base bleed shells. Burst rate of fire is 3 shells in 15 seconds. Maximum rate of fire is 8 rounds in 1 minute. The sustained rate of fire lies lower.

Mobility

The M-83 is towed by a heavy off-road truck which also carries the crew and ammunition. The M-83 has no APU and is too heavy to be manhandled.

Users

The M-83 was adopted only by the Finnish forces under the designation 155 K 83. Production numbers are reported to be 18, 54 or 108 pieces. The newer Patria-Vammas 155 GH 52 APU is based on the design of the Tampella M-83.
