Waltham-based Raytheon Co. is now developing next generation highly destructive missiles for Israel which they believe are potentially protective against Iran threats.

Military analysts tagged the move as a real change which was just a beginning. The new missiles are being brought to Lebanon by Hezbollah militant group. The missiles will be test fired in coming days at Negev desert in Israel.

The country is relying on missile called David's Sling to make it an attraction in its defense system. It is designed to compete with the current missile of the country named Iron Dome. Iron Dome recently destroyed 400 incoming rockets from Gaza in a conflict.

Hesbollah's new missiles are designed by Iran and Russia and are imported from Syria. They are said to have a range of 150 miles and are equipped with a guidance system making the populated areas more vulnerable to them.

David Sling's development has been funded by Israeli giant Raefel with a total sum of $130 million in past three years, as revealed by the records. If the missiles are acceptable, the US will be supporting it with the rest of the required funds.

"It is designed to defeat a variety of short-range ballistic missiles, large caliber rockets and cruise missiles", stated Raytheon.
