Ageing aircraft 2 – keeping Apaches sharp

US Army aviation has had its modernisation tribulations, including cancellation of the Comanche and the recent struggles with Bell’s ARH, but the Apache programme looks like a model for how to renew an ageing fleet – more than once. The AH-64s have been remanufactured once, from As to Ds, and are about to go through the process again as AH-64Ds are upgraded from Block IIs to Block IIIs.

And remanufacturing has enabled Boeing to keep the Apache line open so it can now build new AH-64Ds to replace aircraft lost in combat.

The US Army has already ordered 47 new Block II “wartime replacement aircraft” – WRAs – and just posted a pre-solicitation notice for 30 additional Block III WRAs it expects to procure with war-related supplemental funding – 12 in FY08, 12 in FY09 and six in FY10. In addition, the Army plans to award Boeing a contract to reman 24 more As to Ds. That will make a total of just under 700 AH-64Ds for the US Army, and will take Apache production beyond the 30-year mark.

Don’t look for a replacement any time soon…
