In the lab it worked perfectly. The different systems aimed at defending Israel from ballistic missiles "talked" with each other and the threat was challenged with good results.
A short time before Washington turned its back to Egypt under President Mubarak, it demonstrated its obligation to help Israel in case it is attacked by ballistic missiles.
Recently, a joint US-Israeli exercise was carried out in the Elisra Active Defense Battle Lab, jointly shared by the Israeli Air Force (IAF), the Israeli Ministry of Defense (IMOD) and the U.S. Department of Defense (DOD).
The unique active defence battle lab has been developed and maintained by Elisra, since its inception in the early 90s, under contract with the IMOD and the US Missile Defense Agency (MDA). An end-to-end simulator of Theater Missile Defense, the Lab simulates attacks against defended assets, and the operation of defense systems against those attacks.
Elisra is jointly owned by Elbit systems and Israel Aerospace Industries (IAI).
The computerised exercise was wide in scope, including operational forces and combat fighters while simulating a ballistic missile attack on Israel and the use of Israeli and US. Missile Defense Systems.
A large group of US and Israeli officers from the various operational units participated in the exercise and evaluated the overall operational architecture of the IAF's Active Defense Array, which was set to function in conjunction with the US systems that are deployed in Israel.
The active defense battle lab was developed by Elisra to be the most advanced battle lab in the world for simulating Active Defense against ballistic missiles. The lab in an underground highly secured facilty, is also used to develop the doctrine, coordination and concept of operation between the joint forces and to help engineers to build the Active Missile Defense Systems Architecture.
In the past, the US has stationed Patriot PAC-3 missiles and Aegis ships in Israel and in the Mediterranean to work together with Israel's indigenous Arrow-2 anti ballistic missile system.
