On May 4, local time, senior U.S. defense officials revealed that more than 90 percent of the 90 howitzers the U.S. promised to supply to Ukraine had already arrived in Ukraine. Nearly 90,000 of the 144,000 artillery shells that the U.S. promised to deliver to Ukraine are now. It has also arrived in Ukraine.

Defense officials said how the weapons and equipment, once handed over to Ukraine, would be up to the Ukrainians, and the U.S. did not continue to track their whereabouts and uses.

  Ukrainian media reported that the United States had handed over five of the 17 Soviet-era Mi-17 helicopters to Ukraine.
