A-10C Thunderbolt II on Hog Patrol.
In 2005, the entire A-10 fleet also began receiving the Precision Engagement upgrades that include an improved fire control system (FCS), electronic countermeasures (ECM), and the ability to aim smart bombs. The aircraft that receive this upgrade are redesignated A-10C. The A-10 will receive a service life extension program (SLEP) upgrade with many receiving new wings. A contract to build 242 new A-10 wing sets was awarded to Boeing in June 2007. In July 2010, the USAF issued Raytheon a contract to integrate a Helmet Mounted Integrated Targeting (HMIT) system into A-10Cs.
The Government Accounting Office in 2007 estimated the cost of upgrading, refurbishing, and service life extension plans for the A-10 force to total $2.25 billion through 2013. Modifications to provide precision weapons capability are well underway. The Air Force Material Command's Ogden Air Logistics Center at Hill AFB, Utah completed work on its 100th A-10 precision engagement upgrade in January 2008. The C model upgrades are to be completed in 2011.
