WASHINGTON, July 29 - The U.S. will send $1.7 billion in military aid to Ukraine, officials announced on Monday, including an array of munitions for air defense systems, artillery, mortars and anti-tank and anti-ship missiles.

The package includes $1.5 billion in funding for long-term contracts through the Ukraine Security Assistance Initiative, and $200 million in immediate military aid taken from Pentagon stockpiles, The Associated Press reported.

The latest infusion of weapons comes a bit more than two weeks after the NATO summit in Washington, where allies focused a significant amount of time on shoring up support for Ukraine as it fends off Russian forces. President Joe Biden announced during the summit that the U.S. would send a Patriot missile battery to Ukraine, answering a key plea from Ukrainian President Volodymyr Zelenskyy.

NATO members agreed to create a new program to provide reliable military aid to Ukraine and prepare for its eventual membership in the alliance. And they declared Ukraine was on an “ irreversible ” path to join NATO.

In the latest package, air defense munitions for National Advanced Surface-to-Air Missile Systems, or NASAMS, and High Mobility Artillery Rocket Systems, or HIMARS, as well as Javelin and other missiles will be provided through presidential drawdown authority, which allows the Pentagon to pull the weapons directly from its shelves. The package also includes anti-armor systems, artillery, small arms, demolition equipment and other spare parts and maintenance.

The Pentagon said the longer-term contracted weapons will include “capabilities to augment” Ukraine’s air defenses, including short- and medium-range munitions. The USAI will also provide funding for mortar rounds, anti-armor systems, electronic warfare equipment, explosives, secure communications systems and commercial satellite imagery services.

The weapons and equipment provided through USAI will go through the contracting process and so won’t get to the warfront for months or years.

With the latest funding, the U.S. has now sent more than $55.4 billion in security assistance to Ukraine since Russia’s invasion in February 2022.

White House national security spokesman John Kirby said Monday that the package includes “key capabilities for the fight.” He said this is the ninth military aid package for Ukraine since late April, when Congress finally passed supplemental funding for aid to Kyiv after months of gridlock and delays.

At that time, he said, “there were legitimate concerns that Russia would achieve a strategic breakthrough on the battlefield by the summer.” But since the funding passed Congress, “Ukraine’s defensive lines have been fortified and Ukrainian forces have continued to fight bravely and repel Russia’s advances.” (ap/ez)
