The AS-90 is used by five regiments of the Royal Horse Artillery and Royal Artillery.
AS-90 was designed and built by Vickers Shipbuilding and Engineering (VSEL, owned by BAE Systems since 1999). They made 179 AS-90s from 1992 to 1995. This cost £300 million.
In 2002 BAE Systems were asked to give 96 British Army AS-90s a 52 calibre gun. This would make the range 30 km. With special shells, it would be able to reach 60 to 80 km.[2] However, this project ended up being ended.[3]
Development
AS-90 started in the mid-1980s. It was made on a "gamble" that the SP70 would fail. When this happened, the Ministry of Defence (MoD) asked for a new vehiicle. Four designs were handed in, and AS-90 was the only one that the MoD liked.
The MoD has tried to get the Royal Navy's main ship gun to be able to use the barrel and breech from the AS-90.[4] This would make the gun calibre of the British Army and Royal Navy the same. This would help with ammunition logistics. This would also make it possible for the Army and Navy to help each other develop weapons.[5]
Design
The AS-90 has a special power unit. This is used so that the engine does not have to keep running. This is done to keep the batteries charged while the AS-90 is not moving.
The gun can be started up when it is fully closed down in less than one minute.
The AS-90 has a special computer called the Turret Control Computer (TCC). The TCC controls all main functions of the turret.[6]
Features
Different kinds of AS-90
AS-90D - Changed for use in the desert. This model has more cooling for the engine and other machines.
