—Missiles cost around $40,000 a piece. In 2010, the U.S. provided $200 million to expand development. Additional funding is currently being considered, with $70 million already allocated for the 2012 fiscal year.

—The system is part of what Israel calls its "multilayer missile defense". It is meant to protect against the tens of thousands of short-range rockets possessed by militants in the Gaza Strip and Hezbollah guerrillas in Lebanon. Israel has also deployed its "Arrow" missile defense systems for long-range threats from Iran. The military says its new "David's Sling" system, being developed by Rafael to stop medium-range missiles, will be activated by 2014.
