The Iron Dome is a counter-rocket, artillery, and mortar (C-RAM) weapons system that can also defend against helicopters and other aircraft, as well as UAVs at very short range, according to its Israeli manufacturer Rafael Advanced Defense Systems. Ten of the systems are currently in use in Israel.
Iron Dome has different variants — the I-DOME is fully mobile and fits on a single truck, and the C-DOME is the naval version of the system. The US version, called SKYHUNTER, is manufactured by Rafael and Raytheon.

Iron Dome can operate in all weather conditions and at any time; one launcher holds 20 intercept missiles at a given time. The system uses a radar to detect an incoming projectile. The radar tracks the projectile while also alerting the other system components — the battle management and weapons control (BMC) component and the launcher — of the incoming threat. It also estimates where incoming projectiles will hit and only focuses on those threats that will fall in the area the system is meant to protect. Rafael boasts that this strategic targeting makes the system extremely cost-effective.
Rafael Advanced Defense Systems builds the Israeli Iron Dome defense system; the two US systems will be built by Rafael and Raytheon. Many of the components of Iron Dome's Tamir missiles are made by Raytheon in the US.
Israel uses the Iron Dome to intercept rocket attacks from Hamas in Gaza and Hezbollah in southern Lebanon. It's had the system in place since 2011.

It's unclear when the systems will be delivered, and how and where they will be deployed, but Defense News reported that parts of the system may be integrated into the Indirect Fires Protection Capability program.
The Phalanx close-in weapon system (CIWS) is comparable to the Iron Dome, but instead of missiles, it rapid-fires bullets against incoming threats at sea and on land. The system is manufactured by Raytheon and employs a radar-guided gun that's controlled by a computer and counters anti-ship missiles at sea. On land, the Phalanx is part of the Army's C-RAM system. It's used on all Navy surface combatant ship classes.
The Iron Dome is used in conjunction with David's Sling, which provides medium-range air defense and is produced by Rafael and Raytheon.
Defense News reported on August 12 that the US had purchased two Iron Dome systems, although it's unclear how much the Department of Defense paid for them, or where or how they will be deployed.
While the system has been very useful for Israel against more rudimentary Hamas- and Hezbollah-launched projectiles, it would be less so against weapons like hypersonic missiles, which can maneuver midflight.

The Tamir missiles, which Iron Dome uses in its launchers, are mostly manufactured from parts made in the US and can attack targets anywhere from 4 to 70 km away.
