Israel has used the grants to finance orders of F-35 Joint Strike Fighters

Israel has used the grants to finance orders of F-35 Joint Strike Fighters, a stealth aircraft considered the most advanced ever made. It has so far ordered 75 and taken delivery of more than 30 of the aircraft. It was the first country other than the US to receive an F-35 and the first to use one in combat.

Part of the aid - $500m annually - is set aside to fund missile defence programmes, including the jointly-developed Iron Dome, Arrow and David's Sling systems. Israel has relied on them during the war to defend itself against rocket, missile and drone attacks by Palestinian armed groups in Gaza, as well as other Iran-backed armed groups based in Lebanon, Syria and Iraq.

In the days after Hamas's 7 October attack, President Joe Biden said the US was "surging additional military assistance" to Israel.

Since the start of the war, only two US military sales to Israel have been made public after receiving emergency approval - one for 14,000 rounds of tank ammunition worth $106m and the other for $147m of components to make 155mm artillery shells.

But US media report that President Joe Biden's administration has also quietly made more than 100 military sales to Israel, most falling below the dollar amount that would require Congress to be formally notified. They are said to include thousands of precision-guided munitions, small-diameter bombs, bunker busters and small arms.
