The U.S. has provided Israel with an advanced radar system to give early warning in the event of an Iranian missile attack. The system has been set up at an air base in the Negev desert in southern Israel. Israeli officials say 120 American military personnel have been deployed at the base to operate the radar.
Their has been growing regional tension over Iran's nuclear program. The West fears that Tehran is developing nuclear weapons, but Iran says the program is for peaceful purposes.
"If I was sitting in Iran I would see this just as a signal that they could very well be involved in a conflict that they do not want," Israeli analyst Gerald Steinberg said.
