The US Army has awarded Lockheed Martin a follow-on Performance Based Logistics (PBL) contract to support sensor and sight systems on the AH-64 Apache helicopter.

The contract will support the Target Acquisition Designation Sight/Pilot Night Vision Sensor (TADS/PNVS) and Modernised TADS/PNVS (M-TADS/PNVS) systems on the AH-64 Apache.

The PBL contract provides complete post-production supply chain management, including spares planning, procurement, repairs, maintenance, modifications and inventory management of fielded systems.

The original PBL contract awarded in 2007, established a system of continuous improvements supporting the AH-64 Apache TADS/PNVS and M-TADS/PNVS programmes.

The value of the first year of the contract was $117.8m followed by the 2008 contract worth $76.6m. The new contract has a potential value of $89m for 2009.
