DRS Technologies has been awarded a contract by the US Army Research, Development and Engineering Command (RDECOM) to provide advanced thermal weapon sights (TWS).

The latest $68.2m contract brings the original five-year indefinite-delivery, indefinite-quantity (IDIQ) contract awarded in July 2007 to $460m.

The follow-on order will include light, medium and heavy-weapon thermal sights, which will enable soldiers to conduct day / night surveillance and target acquisition.

The TWS uses 25-micron uncooled vanadium oxide (VOx) detectors to provide the troops with a clear view of the battlefield and to accurately detect targets.

About 50,000 TWS have been manufactured and delivered to the US Army to date since 2004.
