Around the end of the 60s and the beginning of the 70s, the Norwegian Army’s Supply Command (HFK) and Kongsberg Våpenfabrikk entered into a development collaboration with Svense Hagglunds Vehicle for the delivery of NM135 Storm armored vehicles. they then had American M113A1 carriages which were fitted with a turret from Hagglunds and weapons from Kongsberg Våpenfabrikk. They also acquired 39 extra M113 carriages from the USA for this purpose. a total of 53 such wagons were finally delivered in 1981
The main reinforcement on this carriage was a non-stabilized Rheinmetall Mk.20 RH-202 in caliber 20mm, the turret with the cannon was located in the right front corner of the carriage. The ammunition it uses is 20x139mm and the gun has a rate of fire of up to 900 rounds per minute. with this turret a coaxial Rheinmetall MG3 7.62x51mm NATO was also mounted above the 20mm cannon. this had a rate of fire of 1000 to 1300 rounds per minute.
behind the tower there was a 71mm LYRAN bomb launcher for launching light grenades, this also had the option of firing both smoke grenades and explosive grenades. regarding the smoke ejectors, 6 pieces were installed.
This turret was operated manually and had to be operated by hand, there was a rotary lever for elevation correction and a lever for lateral correction, if the gunner needed extra fast correction, he could engage an exchange gear using a foot pedal.
the weapon’s mechanism was electromechanical, and the firing control was on the elevation lever with two spring-loaded buttons for each weapon. if you were to be unlucky and experience a fault with the power supply in the carriage, the shooter would still have the option of firing the cannon with the help of a mechanical trigger placed on the floor of the carriage which you used your foot on “foot trigger”.
sniper scope provided 15x magnification with no thermal or night capability. the control panel for using the smoke grenades was mounted on the wall in front of the gunner, while the switch for the LYRAN bomb launcher was mounted at the tank commander’s place.
This is another Norwegian tank, it is based on the proven M 113A1, but has been modified for the Norwegian defense by Kongsberg Våpenfabrikk by mounting a turret with a rapid-firing 20 mm cannon on the right side at the front of the tank.
The background for this modification was a desire to give the Stormes kadrones greater firepower, this solution was in principle similar to the one chosen by Switzerland to upgrade the carriages, but with a different type of cannon.
The solution was developed at the end of the 1970s and was not entirely successful. The towers were very narrow and there were a number of problems with the weapon system. After the wagons were modified, including the ammunition supply in the 1990s, this improved.
The first wagons entered service in 1981 and were, together with the M113, the standard wagon at the grand squadrons until the CV9030N came with full weight from 1998.
Most of the wagons were phased out around the year 2000, some should still be partially in service for some more years
