sraeli Iron Dome intercepts rockets from Gaza airstrike attack

What is Iron Dome?
Israel’s Iron Dome is an air defense system developed by the Israeli firms Rafael Advanced Defense Systems and Israel Aerospace Industries, with financial and technical support from the United States.

First put into service in 2011, it is designed to stop short-range rockets and artillery like those fired from Gaza. Two separate systems, known as David’s Sling and Arrow, are designed for medium- and long-range threats, including planes, drones, rockets, and missiles.

Iron Dome relies on a system of radar and analysis to determine if an incoming rocket is a threat, only firing an interceptor if the incoming rocket risks hitting a populated area or important infrastructure.

The interceptors, which are fired vertically either from mobile units or a static launch site, are designed to detonate the incoming rocket in the air, producing the explosions in the sky that have come to accompany warning sirens during recent Israeli-Palestinian conflicts.
peaking to Israel Hayom this week, defense officials said that the hardware had not changed since the system was first deployed, but that new software changes had made the system more capable as the years went by.
The system’s comparatively low cost — as it only fires on threats to human life or infrastructure, fewer interceptors are needed — also makes it attractive to foreign governments, including the U.S. Army which has bought two batteries itself.
