With most US military aid stopped,
Military supplies from U.S. to Ukraine continue. In fact, a USAF C130J Hercules transport is about to land in Rzeszow in a few minutes.
Lots of US supply flights to Ukraine last week, too. Including cluster artillery shells from Turkey.
During the Biden administration, Ukraine received half the weapons from Presidential Drawdown Authority(PDA) and half from Ukraine Security Assistance Initiative(USAI). PDA aid was from Pentagon stocks and was sent asap, USAI was purchased from US defense contractors and took a year or more in delivery. PDA aid has stopped, since there is no new congressional funding.
Trump paused USAI delivery.
