The Terminal High Altitude Area Defense (THAAD) is a missile system that intercepts incoming ballistic missiles in their terminal phase. THAAD is designed to intercept targets both inside and outside the atmosphere. It can intercept missiles at altitudes of 40-150 km and ranges of up to 200 km. THAAD is highly effective, with a 100% intercept success rate in flight tests. It can mitigate the potential effects of enemy intermediate- and short-range ballistic missiles, even hypersonic versions. THAAD's non-explosive, hit-to-kill kinetic impact minimizes risk of detonation. The estimated cost of a THAAD system is $1.135 billion.

According to U.S. Defense Officials, the Army is currently Scrambling to Deploy at least 12 Air Defense Systems to the multiple Countries across the Middle East before the Israeli Invasion of the Gaza Strip is set to soon begin. The Terminal High Altitude Area Defense (THAAD) Battery for use against Ballistic Missiles is currently on its way to Saudi Arabia from Fort Bliss, Texas, while at least 11 MIM-104 Patriot Surface-to-Air Missile Systems from both Fort Liberty, North Carolina and Fort Sill, Oklahoma are heading to Locations in Kuwait, Jordan, Iraq, Saudi Arabia, Qatar and the United Arab Emirates.
