The number of United States weapons shipments to Israel dropped significantly after the first four months of the Israel-Hamas war, according to figures published Thursday by the Haaretz daily.

The publication of the figures come after Prime Minister Benjamin Netanyahu’s public claim last week that the US has been “withholding” weapons shipments from Israel.

Tracking the number of American military and civilian cargo planes landing in Israel from US military bases around the globe, Haaretz tallied 173 deliveries to date since October 7. The majority of flights landed in October (22), November (47), December (32), and January (20).

Then, figures began tailing off significantly, with only eight planes arriving in February and 11 in March.

April saw a slight uptick to 17 against the backdrop of the Iranian missile and drone attack against Israel, which the US helped the Israel Defense Forces thwart.

But May and June saw a return to lower numbers, with seven and nine shipments landing in Israel respectively.

The tally doesn’t include another 100 leased cargo planes that originated from non-US Army bases. Also left out of the tally were dozens of US military planes that landed in Israel as part of visits by senior American officials, Haaretz said. Maritime arms shipments to Israel weren’t included either, even though ships are able to carry much larger cargo than planes.

On Wednesday, Defense Minister Yoav Gallant and the Biden administration announced separately that progress had been made toward resolving what Jerusalem considers to be an insufficient flow of arms.

A senior Biden administration official briefing reporters confirmed for the first time that there had been some “bottlenecks” in weapons transfers that are now being addressed.

The official clarified that these bottlenecks weren’t intentional and that Gallant’s meetings with top officials in Washington were an opportunity for the US to order the acceleration of certain shipments while reprioritizing others based on Israel’s needs.

The comments were the closest the administration has come to confirming Netanyahu’s public claim last week that the US has been “withholding” weapons shipments and that there had been a “dramatic drop” in transfers. The accusation made in a video statement infuriated Washington, which vociferously denied the assertion and insisted that it has only held one transfer of heavy bombs that Biden didn’t want the IDF using in the densely populated Palestinian city of Rafah.

As for other weapons shipments, the senior administration official said, “There are some things we are able to maybe pull up a little faster or reprioritize.”

“The progress made [during Gallant’s meetings] was the ability to sit down with the people who do this work every day and go through every single case and where it is in the system.”

“Where there were some misunderstandings, those were clarified,” he added, noting the highly complex bureaucracy within the US weapons transfer system.

A US team went through each of the hundreds of planned weapons shipments with Israeli counterparts, explaining where each stood in the transfer process, the senior administration official said.

Further explaining the apparent slowdown, a second US official told The Times of Israel that Jerusalem submitted fewer weapons and ammunition requests in recent months as the intensity of its fighting in Gaza waned.

The official said that during the early months of the war, the US had been able to expedite the transfer of weapons that had been further along in the approval process. In recent months, though, such shipments ran low.

Moreover, Axios reported that some officials in the administration interpreted Biden’s freeze of the shipment of 2,000-pound bombs as a signal that all arms shipments should be scrutinized more closely, slowing the process in comparison to the beginning of the war.

There is also concern in Washington about a potential Israeli preemptive offensive against Hezbollah in Lebanon, which the administration fears could lead to a regional war, the second official said.

Nonetheless, the senior administration official briefing reporters stressed that the US has sent more than $6.5 billion in weapons to Israel since October 7, with nearly $3 billion alone in May.
