Americans know that the U.S. government and defense industry exports huge amounts of military goods to Israel — but they may not be aware that in some cases these shipments travel beside them.

On Saturday afternoon, a cargo airplane carrying 14 tons of explosive materials bound for an Israeli weapons manufacturing company is expected to fly out of John F. Kennedy International Airport in New York on Saturday afternoon, according to air cargo documents reviewed by The Intercept.

The explosive material, grade A nitrocellulose, is a widely used industrial material that plays a key role in making ammunition — from sniper bullets to rockets. According to the air cargo documents obtained by journalists at Irish news site The Ditch and researchers with the Palestinian Youth Movement, 51 pallets of nitrocellulose are expected to be delivered to the Israeli weapons manufacturing company IMI Systems, headquartered outside of Tel Aviv in the city of Ramat Hasharon. The main client of IMI Systems, previously known as Israeli Military Industries, is the Israel Defense Forces.

Saturday’s cargo flight is the largest single shipment of explosives to pass through NYC’s busiest airport.

The cargo flight by Challenge Airlines Israel is scheduled to depart from JFK at 2 p.m. on Saturday and land in Ben Gurion Airport in Tel Aviv on Sunday, according to flight information. The manufacturer of the materials is not known, but the cargo’s sender is listed as deriving from a Los Angeles ZIP code. While other weapons-related shipments have been sent from JFK to Israel, Saturday’s cargo flight is the first confirmed shipment of nitrocellulose and the largest single shipment of explosives to pass through New York City’s busiest airport, said journalist and lawyer Roman Shortall, co-founder of The Ditch.

Previously, The Ditch has reported on other military equipment flown out of the JFK airport, including ammunition propellants, detonating fuses, tear gas, F-35 combat jet parts, and
