Too few Iron Domes, cities exposed

Israel's Home Front chief says cities will likely be unprotected by Iron Dome anti-missile systems if war erupts because military installations will get priority, a warning observers say is meant to pressure Washington not to cut military aid to the Jewish state.
At present, only five batteries of Iron Dome, developed by Rafael Advanced Defense Systems to shoot down short-range rockets, are operational. Israeli military planners say at least 13 are required to provide full-scale defense across the country.
Israel has had to cut defense spending in recent years and it is only hefty funding by the United States that has financed development and production of Iron Dome.
Each battery costs around $50 million and consists of 20 Tamir interceptors that cost around $50,000 each.
