With the collapse of the RAH-66 Comanche program, and rededication of its funding into the ARH-70 Armed Reconnaissance Helicopter (ARH), the UH-145 Light Utility Helicopter (LUH), and other programs, the AH-64 Apache will remain the primary attack helicopter flown by the US and its allies over the coming decades. Unsurprisingly, some degree of remanufacturing and conversions to AH-64D status are either completed or ongoing for almost all AH-64A Apache owners.
In January 2007, Boeing announced a $1.149 billion extended Block II contract for the remanufacture of 96 US. Army AH-64D Apache Longbow helicopters, as well as 30 AH-64Ds for the United Arab Emirates. That number has continued to grow, until it encompassed all of the US Army’s remaining AH-64A Apache attack helicopters.
