Textron Marine & Land Systems (TM&LS) has secured a contract to conduct work on the US Army's high-mobility multi-purpose wheeled vehicles (HMMWVs) modernised expanded capacity vehicle survivability (MECV-S) programme.

Awarded by the Army Tank-Automotive and Armaments Command (TACOM), the $3.29m firm-fixed price contract seeks supply of innovative crew protection and vehicle survivability improvements for the army's two HMMWV vehicles.

The company is collaborating with Granite Tactical Vehicles to perform work on the programme, with follow-on potential expected to include work on up to 5,750 vehicles.

Under the contract, the team will install its MECV-S protection system onboard two government-furnished HMMWVs followed by their delivery for improvised explosive device (IED) evaluations at the Aberdeen Proving Ground in Maryland, US, in the summer 2013.

TM&LS senior vice-president and general manager Tom Walmsley said the TM&LS/Granite MECV-S solution is capable of replacing the existing HMMWV crew compartment in a one-for-one exchange.

"It offers vehicle occupants an armoured monocoque V-hull protective capsule and restores the vehicle's tactical mobility with proven components," Walmsley said.

In addition, the computer aided design (CAD) models will be submitted for further analysis.

Having a lower centre of gravity than an up-armoured HMMWV, the lightweight and highly-survivable TM&LS/Granite vehicle protection system is also capable of withstanding small arms fire, blasts and the secondary effects of blasts, including as fire, crushing, rollover and collision.

Fully compatible with all existing HMMWV variants, the production-ready Technology Readiness Level 8 system features angles and a V-shaped blast deflection under-body plate to offer mine-resistant ambush protected (MRAP) style protection to troops.

The system can be easily supported and maintained, while also retaining all of the original HMMWV cab characteristics by using existing controls, linkages and drive systems.

An array of scalable armour technologies is currently being sought by the army to meet the existing and future threats to its HMMWV combat vehicle fleet.
