Most of the weapons and defense systems that are supplied to Ukraine are provided under a drawdown from Department of Defense stocks. These are often legacy and decades old technology systems that can now be replaced with orders for new and modernized systems from U.S. defense contractors. Money from Ukraine aid funding will be used for these purchases. Some example include:
- M2A2 Bradly Infantry Fighting Vehicles, introduced in the 1980's, are being replaced with modern Bradley A3s. (Image: Shipment of Bradleys to Ukraine, Oz Suguitan, U.S. Transportation Command, U.S. DoD).
- PAC-2 PATRIOT missiles, introduced in the 1980's, can be replaced with more modern PAC-3 missiles.
- Army Tactical Missile System (ATACMS), introduced in 1986, can be replaced with Precision Strike Missiles (PrSM).
