Image:AS90.JPG The AS-90 (Braveheart) is a lightly-armoured self-propelled artillery piece used by the British Army. A self-propelled gun, it was first delivered in 1993.
The AS90 is used by five field regiments of the Royal Regiment of Artillery and Royal Horse Artillery;1 RHA, 3 RHA, 4 RA, 19 RA and 26 RA, replacing the FV433 "Abbot" 105 mm SPG, the M109 155 mm SPG, or the FH 70 155 mm towed gun. It is built by the Armaments division of Vickers Shipbuilding and Engineering (VSEL, owned by BAE Systems since 1999), who provided 179 vehicles from 1992-95 at a cost of £300 million.
The AS90 is fitted with a 155 mm gun (39 calibre) which fires the NATO L15 projectile out to a range of 24.7 km (30 km with Extended Range Ammunition). From 2002 the gun was rebarrelled to 52 calibre to push the unassisted range to 30 km and the ERA range to around 70 km.
The vehicle is fitted with an autonomous navigation and gun laying system (AGLS) and all main turret functions are controlled by a Turret Control Computer (TCC).
