The priority list reflects the security threats the defense establishment believes Israel will face in the next few years, i.e. the eventuality of a prolonged war, which would necessitate using the IAF widely to attack many targets, along with ensuring enough spare parts and supplies.

Israel also requested JDAM bombs, seeking to significantly increase the number of such munitions already in its arsenal. The JDAM bombs have been used increasingly in recent operations, including in the Second Lebanon War in 2006 and Operation Cast Lead in 2008.

Israel is also seeking to increase the amount of gear held by the American army in their emergency stores in Israel by 50% - from $800 million to $1.2 billion. The Obama administration placed the stores in Israel in December, as part of a number of steps to improve U.S. assistance to Israeli security. To date, $600 million worth of American emergency equipment has been placed in Israel.

The American stores hold rockets, bombs, aircraft ammunition and armored vehicles, along with other weapons. The gear fully matches equipment already used by the Israel Defense Forces and is cataloged upon arrival to ensure quick and easy access at a time of need, pending permission from the United States. The American move has a dual purpose: bringing military equipment closer to areas in which Americans might need to fight, and assisting the U.S. ally should the need arise.

Senior military sources told Haaretz that the IDF attaches great importance to the stores; in the event of an extensive conflict, considerable time will pass before an airlift of ammunition and spare parts - similar to the one operated during the 1973 Arab-Israeli war - gets under way.
