Main Battle Tank Light Anti-Armour Weapon (MBT LAW) (formerly NLAW) is a man-portable, short-range anti-armour weapon.

It will provide a capability out to a range of 600m, against main battle tanks and light armoured vehicles; have the ability to be fired from enclosed spaces and defensive positions and be a means of attack against personnel in structures.

The MBT LAW prime contractor is SAAB Bofors Dynamics of Sweden, with Thales Air Defence Ltd as the main UK sub-contractor.

Deliveries began in December 2008 and the system replaces LAW 80 and the interim ILAW (Bofors AT-4).

The final cost of the MBT LAW contract is in the order of £400M.

The MBT LAW system has been developed in a collaborative programme with Sweden. Entry into service beganin mid-2009, although it had been subject to some delays, as a result of qualification problems.
