Boffors Stridsvagn (Strv) 103A/B/C The Strv 103 (or Bofors S-tank) is the only turretless MET in operational service in the world. The fixed 105 mm L74 rifled gun is laid in elevation/ depression by tilting the hull via a hydropneumatic suspension system and in azimuth by turning the whole vehicle using only its tracks. The ammunition types used include APFSDS-T, APDS, HESH and smoke. Three versions have been produced to-date: Strv 103A - the original production batch with no flotation screen (to allow
amphibious operations at max waterspeed of 6 km/h) nor integral under glacis dozer blade. All upgraded to Strv 103B standard. Strv 103B - standard production model with flotation screen assembly and integral dozer blade beneath the glacis plate to enable vehicle to dig its own fighting positions. Strv 103C - the Strv 103B model upgrade between 1986-1989 with new Detroit Diesel engine, modified transmission and modem computerised fire control system with a gunner's integral laser
Sweden rangefinder sighting assembly. All Strv 103 models were fitted for an NBC system but do not carry one. The Strv 103C has its own dozer blade that folds back under the nose of the tank for digging defensive positions. The only combat support version fielded to-date is a mine-clearing vehicle which is an Strv-103 fitted with the locally designed and built 6000 kg Minvalt mineroller system. The Strv 103 is to be replaced by the Strv 121/122 Leopard 2 (Improved)/Leopard 2 MBTs.
