We hear so much about military expenses and about a few of the vehicles created. The Army has little to show for all it's cancelled systems and billions spents since the 1980's. Here's a list I cobbled together.
Armored Systems Modernization (ASM)
- Block III tank
- Future Infantry Fighting Vehicle
- Combat Mobility Vehicle (CMV)
- Advanced Field Artillery System (Crusader)
- Future Armored Resupply Vehicle
- Line-of-Sight Antitank System (LOSAT)
Armored Gun System (XM8)
Future Combat Systems Manned Ground Vehicles - 9 vehicle types
Ground Combat Vehicle (GCV)
Next Generation Combat Vehicle (Current Program, moving along)
- Armored Multi-Purpose Vehicle (AMPV) (5 variants)
- Mobile Protected Firepower
- Optionally Manned Fighting Vehicle (started, stopped, rebooted)
I didn't list the JTLV (in production) or some others like the Extended Range Cannon Artillery program. I probably missed some things that got cancelled.
