The Pakistan Navy received its seventh and final P-3 Orion in ceremonies at the Lockheed Martin facility in Greenville, South Carolina, on 12 July 2013. The P-3s were delivered to the Pakistan Navy as part of an eight-year aircraft reactivation and upgrade program. Pakistan ordered its P-3s through the US Foreign Military Sales program. More than 800,000 hours were invested in this program returning the P-3 aircraft to service that were reclaimed from the Aerospace Maintenance and Regeneration Group at Davis-Monthan AFB, Arizona. In addition to the Greenville operations, Lockheed Martin Mission Systems and Training was also involved in the program. After upgrades, the Pakistan aircraft are now comparable to the P-3C Anti-Surface Warfare Improvement Program, or AIP, configuration.
