Company command vehicle

In April 1975, FMC received a production contract from the Netherlands with the first deliveries in 1977. The AIFV was designated as the YPR-765 in reference to the XM765 that started this line of development. The Y indicated Dutch production. The P was for pantser (armored) and the R was for rups (tracked). FMC delivered the basic vehicle, but Dutch companies made the final assembly, produced certain components, and completed any modifications.

The infantry fighting vehicle converted from the M113A1

Based upon the lessons learned with the XM765, a new prototype was built by FMC during 1970. Referred to as the product improved (PI) M113A1, it was powered by the turbocharged 6Y53T diesel engine developing 260 gross horsepower. A new torsion tube-over-bar suspension increased the road wheel travel improving the cross-country performance.

The armored personnel carrier XM734 vehicle

In 1967, FMC received a contract to modify two M113A1 armored personnel carriers as prototypes to evaluate the "fight-from-the-vehicle" concept. Designated as the XM765, these vehicles retained the power train, suspension, and tracks of the standard M113A1. The upper rear side armor was sloped and four sets of firing ports and vision blocks were installed on each side.

Armored cavalry assault vehicle m113

The M113 armored personnel carrier was introduced into Vietnam when two ARVN (Army of the Republic of Vietnam) companies were organized and equipped in April 1962. Although it violated the doctrine promulgated by their American advisors, the Vietnamese insisted on fighting mounted in their vehicles, using them as light tanks. The M113's normal armament of one .50 caliber machine gun was supplemented by additional weapons mounted on top of the vehicle. This method of operation proved to be extremely effective under the conditions prevailing in Vietnam and eventually it was adopted by the American advisors. However, by early 1963, it was obvious that shields had to be provided to protect the gunner using the externally mounted weapons.

Miles per hour

The turret was cast aluminum and dual hardness steel. The vehicle was driven by the 6V53T diesel engine with an aluminum block and it developed 300 horsepower at 2,800 rpm. This was the engine used in the M551 Sheridan. The Allison MT650 transmission had five speeds forward and two in reverse. The maximum road speed was estimated as 65 miles per hour and the 90 gallon fuel tank provided a cruising range of approximately 450 miles. The Aerojet water-jet propulsion unit was expected to drive the vehicle at a maximum speed of 5 miles per hour in water.
