The US Department of Defense has released the details of the ~$2.3 billion security assistance package. As previously stated, it includes PDA #60, worth $150 million, and USAI #19, worth ~$2.2 billion. The USAI package is entirely PATRIOT missiles and AMRAAMs. They are linking this to their decision to resequence the delivery schedule for active Foreign Military Sales cases for those two missiles. There were large numbers of PATRIOT missiles and AMRAAMs already on USAI contract for Ukraine prior to this new commitment though.
The drawdown includes more HAWK missiles, additional MFoM ammunition for M142 HIMARS & M270 MLRS, artillery ammo, anti-tank munitions, and more.
