be produced locally) along with 525 M113A-B (similar to the M113A2). The first vehicles were delivered in 1982. Turkey selected the AIFV in 1989, after a competition involving the Alvis Vickers Warrior IFV, Krauss-Maffei PUMA and United Defense LP Armoured Infantry Fighting Vehicle. The total value of the contract for 1,698 vehicles was US$1.076 billion. The first 285 hulls were produced in Belgium, the remaining vehicles were produced entirely in Turkey. A little way into the production run, with 200 vehicles completed, the Turkish AIFV specification was updated to include a more powerful power pack developing 300 horsepower, an Allison X-200-4 transmission and hydrostatic steering from the M113A3. During the production run, a number of changes were made to the armament of the vehicle, including different turret packages, and power packs. Description (per Dutch variant) The hull of the vehicle is made of welded aluminium, with spaced steel laminate armor bolted onto the side and front. The voids of the armor are filled with polyurethane foam, which gives the vehicle extra buoyancy when travelling in the water. Original production AIFVs can swim without deploying flotation curtains, using only a large front-mounted trim vane; they are propelled in the water by their tracks. The engine sits on the front right of the hull, behind a hatch that can be used to remove the complete powerpack. The powerpack is similar to the M113A1, except for a larger radiator capacity and turbocharger. The transmission is also fitted with heavy duty components from the M548 tracked cargo carrier. Immediately to the left of the engine is the driver, above whom is a hatch that opens to the right. The driver has four M27 day periscopes. The driver's center periscope can be replaced by a passive infra-red periscope for night driving. The commander sits immediately behind the driver, and has a cupola that can be completely traversed. The cupola has five periscopes, four of which are M17 day periscopes, the fifth has 1x to 6x variable magnification. The turret is fitted on the right side of the hull behind the engine. The turret, which has electro-hydraulic traverse, can elevate from -10 to +50° and can traverse and elevate at a speed of 60°/sec. The turret mounts an Oerlikon KBA 25 mm B02 cannon with a dual ammunition feed and 180 rounds of ready use ammo, with another 144 rounds stored in the hull. Mounted to
