As Israel's principal ally, the US has significantly boosted military support during Israel's regional military campaigns.
According to the Stockholm International Peace Research Institute, the US accounted for 69% of Israel’s arms supply from 2019 to 2023, a figure that rose to 78%.
By December 2023, the US had delivered over 10,000 tons of weapons valued at $2.4 billion, a number which expanded to 50,000 tons by August 2024, transported via hundreds of aircraft and ships.
The US has supplied Israel with a variety of advanced military equipment, including missiles for the Iron Dome, precision-guided bombs, CH-53 heavy lift helicopters, AH-64 Apache helicopters, 155mm artillery shells, bunker-busting munitions, and armored vehicles.
Since 1946, the US has provided Israel with more than $310 billion in military and economic assistance, adjusted for inflation, according to the Council on Foreign Relations.
A 10-year, $38 billion military aid agreement signed in 2016 continues to provide $3.8 billion annually for foreign military financing and missile defense.
In 2024, emergency packages added billions more in support, including $14.1 billion approved in February and a $2.5 billion arms shipment in March.
The arms deals have faced criticism over concerns regarding their use in civilian areas, with limited oversight from Congress.
By 2024, the US had authorized more than 100 arms agreements to bolster Israel’s missile defense systems and replenish its stockpiles, despite ongoing concerns over their impact on Gaza’s civilian population.
