THAAD has been purchased by the UAE and Saudi Arabia
A dramatic difference between the two systems is the cost: each Arrow interceptor costs $2-3 million, compared to a THAAD interceptor costing about $12-15 million
This is one of the reasons THAAD has so far only been purchased by the UAE and Saudi Arabia, which can afford its costs Germany, which evaluated THAAD against Arrow-3 chose the Israeli system
The first operational interception by THAAD was carried out in January 2022 in the UAE when it was launched against a missile fired by the Houthis
THAAD doesn't add capabilities to Israel that Arrow doesn't already have but additional interception systems increase the Israeli Air Force's ability to intercept even larger barrages should more come from Iran
The defense establishment has been training for several years in the joint operation of THAAD and the SM-3 missile system installed on American missile destroyers carrying the Aegis system
These systems are able to share targets and use each other's radars for enhanced effectiveness
