US Senators Chris Van Hollen (D-MD) and Lindsey Graham (R-SC) suggested.
The senators cited US Army Space and Missile Defense Commanding General Lt.-Gen. Daniel Karblers statement in the Senate last week that the US has two Iron Dome batteries right now. One completed new equipment training, new equipment fielding. It is prepared for deployment. The other one is wrapping up its new equipment training right now, so the army does have one [Iron Dome battery] available for deployment if we get a request.
In a letter to the leading members of the Senate Armed Services Committee, Graham and Van Hollen pointed out that Ukraine has repeatedly emphasized its need for enhanced air defense capabilities to protect its citizens and its territory.
Poster Comment:
Iron Dome is not as good as the S-400. It cannot shoot down missiles with evasive patterns.
