The US Armoured IFV Series

The US Armoured IFV Series Background

(Scroll down for Turkish ACV-S & ACV-300)

The M113 APC had served the US Army well before the appearance of the Russian BMP-1, an Infantry Fighting Vehicle, which offered great protection and offensive capabilities than any APC in US service.

The M113A1 had entered production in 1964 and was used in the late 60’s as the basis for an improved vehicle. The US Army then decided to go with the more heavily armoured and more capable Bradley IFV also developed by FMC, who had manufactured the M113, but was heavily exported.

The improved vehicle saw the addition of module armour on the front (box) and sides (identified by rounded edges with bolts), which was bolted on to the existing aluminium armour frame of the M113. A undesignated laminate armour was then inserted in to these modules.

A new, one man turret was installed, which housed a KBA 25mm auto cannon and a coaxial 7.62mm MG. The 25mm could be elevated from -10 to +50 degree’s and the turret could traverse a full 360. The vehicle can store 324 x 25mm rounds and 1840 x 7.62mm. The vehicle has a bank of 6 smoke grenade launchers. It can also be fitted with an NBC system.

The vehicle has a 3 man crew. The driver sits front left, the commander behind him. The gunner is located in the turret, which is right of the commander. The turret has and can be replaced with a shielded .50cal firing station.

The vehicle which carries 7 equipped troops, is powered by a Detroit Diesel 6V-53T V-6 liquid cooled diesel, generating 264bhp. This is an improved engine of the original used in the M113 series and is located front right of the driver. The vehicle is fully amphibious.
