The US Army is NOT looking to buy new helicopters
With the looming threat of reduced budgetary funds, the Army is looking to cut operational costs. It is retiring the Kiowa Warriors, replacing them with UAS (unmanned aerial systems) to be teamed up with the AH-64E. Also retiring the TH-57, since the fleet is all muli-engined airframes no longer need a single engine trainer! US Army aviation already has 400 non-combat muli-engine airframes (UH-72s) so all but 100 shifted from national guard and reserve units to mother Rucker. The loosing national guard and reserve units get uh-60s. As do the reserve and national guard Apache units (they too loose their attack aircraft to be replaced by Blackhawks)! With this plan, there is no requirement to purchase the airframes from your suggestion!
