The Sidam 25 is a self-propelled anti-aircraft gun developed in Italy from the chassis of the American M113 armoured personnel carrier. Due to the choice of basic chassis for the Sidam 25, components and spare parts are both cheap, and readily available because of the widespread use of the basic M113. Beginning production in 1989, OTO Breda built a large turret to accommodate the four Oerlikon KBA cannon and remodelled the hull of the M113 slightly to provide side-access to the internal space of the vehicle by the addition of a side-mounted door.
[edit] Armament
The Oerlikon KBA cannon have an effective range of about 2,000 metres (6,650 feet) and can engage low-flying targets with good accuracy within that range. Firing at 2,400 rounds per minute, the turret contains 600 rounds of ammunition providing usually, eight bursts of around two seconds each. An internal magazine also houses 30 armour-piercing rounds that can be used against enemy vehicles. The turret can rotate through 360° and the guns can be raised 87° or lowered 5° from the horizontal position.
[edit] Fire control and observation
Target engagement is via optronic equipment.
[edit] Propulsion
The Sidam 25 is powered by a single 6-cylinder Detroit 6V-53T engine, which will deliver 266 hp and drive the Sidam 25 to a top road speed of 69 km/h (40 mph) and allow the vehicle to climb vertical obstacles of about 0.61 metres in height and climb gradients of about 60 per cent incline or cross trenches 1.68 metres wide.
