US Army is seeking a new light tank. Mobile Protected Firepower (MPF) is a new vehicle which will significantly strenghten US Army infantry brigades. The vehicle will be component part of Infantry Brigade Combat Team, and will provide direct fire support. Tank will be used in conditions where distance, terrain or time constraints prevent deployment of heavy armour, essentially fulfilling the role of Stryker MGS.

Light tank will provide infantry with ability to counter enemy armour, fortifications, and to provide freedom of maneuver. Previous concept of light tank, M551 Sheridan, was a failure because of a low-pressure gun intended to fire guided missiles, which turned out too unreliable.

New tank has to be air mobile, with at least C-17 and if possible C-130 being able to carry it. As such, it has to have mass of no more than 32 tonnes. Main armament will be gun of either 105 or 120 mm calibre, capable of destroying armoured vehicles from motion, in all weather conditions. MPF must also be able to traverse obstacles, particularly in urban terrain; as such vehicle will be tracked. Vehicles within ICBT have to be able to operate for 24 hours without refuelling, and armour has to protect against small arms fire and shrapnel. As there are no existing vehicles fulfilling the requirements, new vehicle will have to be developed.

After prototypes are tested, two final choices will enter EMD (Engineering and Manufacturing Development). Each manufacturer will deliver 12 preserial production vehicles, and production should begin in 2022. Production is planned at 26 vehicles in 2022., 28 in 2023., and 50 vehicles per year from 2024. to 2032. First operational unit should receive MPFs in 2025. Price should not be above 6,4 million USD per vehicle.

Candidates are BAE Systems, General Dynamics Land Systems (GDLS) and Science Applications International Corp. (SAIC). BAE Systems is going forward with modernized M8 AGS. Basic vehicle has aluminum armour and, with combat weight of 19,5 tonnes, could be parachute-deployed from aircraft, and 3 to 4 can fit into C-17. Level 2 protection against light cannons mass is 23 tonnes, and with protection against calibres up to 30 mm mass is 25,5 tonnes. General Dynamics will likely base vehicle on Griffin demonstrator, with 120 mm gun and ASCOD / Ajax chassis. SAIC vehicle is based on chassis from Singaporean NGAFV IFV and turret from Belgian CMI Defence company. NGAFV in IFV variant has mass of 29 tonnes, and remotely controlled turret with 30 mm Bushmaster cannon and 7,62 mm coaxial machine gun. Crew is 3 plus 8 infantry, with 70 kph top speed, 24,5 HP/t. MPF would have 105 mm turret Cockerill 3105 with protection up to STANAG 5 level. NGAFV with Cockerill turret would weight 32,5 tonnes.
