Actually, the Army recognized the extraordinary high cost of the logistics supporting/fielding a fixed-wing aircraft at forward deployed locations, like fields, highways, etc, as well as the high cost of fielding maintenance pieces-parts and maintainers, and the heavy cost and logistics demands associated with ammunition storage facilities.
Budgets are put together by each service. A huge issue like transferring a platform from one service to another would be resolved by the Sec Def with presidential agreement and then, only then, is the PB submission sent to the House and Senate.
Congress is where the HAC and SAC take whacks at the PB, as well as the SASC and HASC do their editing, then a conference committee between the House and Senate comes together and horse trading takes place-—all about money and capability and a huge issue like transferring a platform from one service to another would be resolved by the Sec Def with presidential agreement before it is sent to Congress.
Basically, something like a platform transfer would require significant agreement between the losing and gaining service, and then the services would have to be united as they try and convince the Sec Def this transfer should take place. IF the Sec Def is convinced, then he has to convince the president to support this action. IF he is convinced then the PB is sent to Congress.
Not a simple thing and most certainly not something “Congress” would kill unilaterally.
Oh by the way, Weaselly could not find his own butt with assistance of the entire 82nd Airborne. The man left a disaster where ever he went.
