It's a Deal: Army Wants Boeing to Build or Fix 600 AH-64E Apaches
The E model is to be fit for maritime operations. The U.S. Army has expressed a desire to add extended-range fuel tanks to the AH-64E to further increase range and endurance.
The US Army plans to grant Boeing a multiyear contract for the production or remanufacture of up to 600 AH-64E Apache Guardian attack helicopters.
According to a US Army notice online, the contract would consist of a five-year multiyear contract or one-year contract with options from FY2022 to FY2026. Its value is still undisclosed. As told by Flight Global, the army intends on sole sourcing the work to Boeing and posted its plan online so as to give other potentially interested parties a chance to bid.
In 2017, Boeing and the US government signed the first five-year, $3.4 billion contract through which the Army, and an undisclosed foreign military customer, were to acquire the “E” variant of the Apache. As part of that contract, the US Army was to receive 244 remanufactured Apaches, while 24 new ones were to go to the international customer.
