Some Iron Dome systems have been exported. A weakness for most potential markets is that each Iron Dome system protects no more than 100–150 square kilometers; this is effective in a small country like Israel, but not for larger states. Even in Israel the batteries have to be moved around according to perceived risk of attack. Singapore, a small city-state, is reported to have purchased Iron Dome, and the US Army has bought two batteries to protect overseas bases.
