Warrior Capability Sustainment Programme (WCSP) is the program of modernization of MCV-80/FV510 Warrior Infantry Fighting Vehicle.

The contract for modernization was received by the Lockheed Martin UK (LMUK), British unit of the American Lockheed Martin. The upgraded vehicle is also known as Warrior 2.

The WCSP effort has 4 main sections:

• WFLIP (Warrior Fightability Lethality Improvement Programme) to improve turrets and sensors, and add firepower

• WMPS (Warrior Modular Protection System) to add a modular armoring system

• WEEA (Warrior Enhanced Electronic Architecture) to add a fully integrated set of modern, expandable electronics and communications gear

• ABSV (Armoured Battlefield Support Vehicle) to improve the repair and recovery variants that keep the fleet in the field

At the International Armoured Vehicles Conference (IAV 2018) in London, Lockheed Martin reported that eight Warrior 2 were delivered to the Armored Trials and Development Unit (ATDU) in the Dorset, United Kingdom, after the completion of the factory tests.
