Ukraine is getting more help in its war with Russia.

A Patriot air-defense system that was based in Israel will be sent to Ukraine after it is refurbished, four current and former U.S. officials said in recent days, and Western allies are discussing the logistics of Germany or Greece giving another one.

The officials, speaking on the condition of anonymity because of the sensitivity of the discussions, declined to describe President Donald Trump’s view of the decision to transfer more Patriot systems to Ukraine.

The White House’s National Security Council does not provide details on the strength and placement of defense systems, said James Hewitt, a spokesperson for the council. “President Trump has been clear: He wants the war in Ukraine to end and the killing to stop,” he said.

A former White House official said that the Biden administration had secured the agreement with Israel in September, before the election won by Trump. The Defense Department said in a statement that “it continues to provide equipment to Ukraine from previously authorized” packages, referring to weaponry pulled from existing inventories and new purchases.

The delivery, which has not been previously reported, comes as Russia has stepped up its attacks on Ukraine, including an April 24 missile strike on Kyiv, the capital, that was the deadliest since last summer.

A year ago, allies struggled to answer a demand by Ukrainian President Volodymyr Zelenskyy for seven Patriot systems. Although Ukraine now has eight, only six are functioning. The other two are being refurbished, one of the U.S. officials said. With the one from Israel, and one from Germany or Greece, Ukraine would have 10 Patriot systems in total, largely to protect Kyiv.

As Russia has intensified recent attacks, Trump’s recent public remarks on the war have softened in favor of Ukraine.

Trump had a cordial meeting with Zelenskyy at Pope Francis’ funeral in Rome last weekend, after a disastrous one in February in the Oval Office. He has dialed down his negative rhetoric about Zelenskyy and questioned whether Russia is serious about peace talks. A delayed minerals deal with Ukraine was signed Wednesday, paving the way for more U.S. military aid.

On Saturday, Zelenskyy told reporters in Kyiv that the minerals deal could mean the United States would send more air-defense systems.

Under U.S. export rules for sensitive defense equipment, the United States must approve any transfers of the American-made Patriot missile systems to Ukraine, even if they were coming via other countries. The systems are scarce, and their deployment is often a shell game of world hot spots, figuring out which global crisis requires them most to defend U.S. troops, bases and allies.

Trump has made ending the war a signature goal of U.S. foreign policy, but at the same time, has flipped that policy on its head. Even though Russia started the war, Trump has frequently expressed admiration for its president, Vladimir Putin, and adopted some Russian talking points, such as saying that Ukraine should not be able to join NATO and that Ukraine was somehow responsible for the war despite being invaded.

Since the start of the war, Zelenskyy has repeatedly asked for more Patriot systems, saying they were essential to defend his country. Each Patriot surface-to-air system consists of a battery with a powerful radar system and mobile launchers that fire missiles to intercept incoming projectiles.

The United States first sent a Patriot system to Ukraine in April 2023. By January 2024, there were already missile shortages.
