Ukraines Defense in Limbo: U.S. Military Aid Delays Amid Growing Russian Threat

This week, the «America First» approach from the White House affected Ukraine as Washington halted military aid shipments to preserve its own weapon stockpiles.

The halt in assistance occurred even after a report from high-ranking military officials stated that this aid package would not compromise the U.S.’s own military supplies and readiness. Many of the arms were already stationed in Europe when the decision was made.

An insider informed The Economist that the postponed shipment included 30 Patriot air defense missiles, a crucial weapon capable of intercepting the hypersonic missiles Russia has been using against Ukrainian cities.

Ukraine exhausted its supply of Patriot missiles back in May. Only 740 of these missiles, each costing around $4 million, are expected to be manufactured this year. Europe’s nearest alternative is the SAMP/T, but software issues have limited its operational effectiveness.

Last week, President Donald Trump told a visibly emotional Ukrainian journalist that the U.S. would “see if [we] can make some available,” yet made no promises, cautioning that the U.S. needed some for its own defense.

Other air defense systems that have been withheld include 25 Stinger MANPADS and 92 AIM-7 “Sparrow” air-to-air missiles, which could be mounted on Ukraine’s F-16 fighter jets or modified for ground-based defense.

Since Trump returned to the White House, Russia has doubled its drone activity against Ukraine over the past six months.

Whereas earlier strikes may have involved dozens of drones, recent assaults have involved hundreds. For instance, on the night of June 29, Russia launched 477 drones and 60 missiles towards Ukrainian urban areas.

Emergency response and debris clean-up efforts continue following another Russian offensive, characterized as one of the largest and most calculated air strikes. Overall, 550 targets were struck, including at least 330 Russian-Iranian “Shahed” drones, along with missiles.

Russia has also upgraded its drone capabilities and strategies in an ongoing arms race against Ukraine.

The recent aerial attack, the largest since the conflict began, came mere hours after a phone conversation between President Donald Trump and Russian President Vladimir Putin. Trump expressed disappointment, stating that Putin showed no willingness to halt the invasion of Ukraine.

“With each escalating airstrike on Ukrainian cities, Putin is reiterating what he conveyed to Trump: his lack of interest in a ceasefire or diplomatic talks, with his primary aim being the annihilation of Ukrainian sovereignty,” commented John Foreman, the former U.K. defense attaché in Moscow, to The Moscow Times.

The pause in aid could impact battlefield dynamics. Ukraine was originally set to receive approximately 8,500 rounds of 155mm artillery from U.S. reserves, equivalent to about 20% of a month’s production.

Last year, Ukraine averaged around 3,600 artillery rounds fired daily, likely due to units managing their ammo carefully as delays in U.S. assistance limited new supplies.

European nations are expected to boost their production of 155mm shells to 2 million annually by 2026. Ukraine has also begun domestic production of these shells, as well as 122mm munitions for its remaining Soviet-era artillery, with plans to produce 100,000 shells in 2025 and 600,000 the following year.

In the meantime, Russia is reportedly manufacturing as much ammunition in three months as NATO does in an entire year, according to NATO’s Secretary General Mark Rutte, and has increased its imports of chemicals necessary for explosives.

Additionally, Russia is supported by North Korea, which provides half of the shells used in combat, based on Western intelligence. Despite many of these shells being of subpar quality, their quantity has facilitated Russia’s territorial gains in Ukraine since the onset of the deliveries.

Other withheld weapons include 125 AT4 shoulder-fired launchers and 142 Hellfire missiles, both crucial for neutralizing tanks and fortified Russian positions. Ukraine was also scheduled to receive over 250 artillery rockets compatible with its HIMARS systems, which are used to strike Russian ammunition storage facilities and logistical centers.

The capability to hit these targets helps to diminish some of Russia’s material superiority. Ukraine’s Commander-in-Chief, Oleksandr Syrsky, claimed in April that they managed to cut Russia’s daily ammunition usage in half to 23,000 rounds, although that figure has since risen as Russian supplies increased.

Experts assert that no single weapon is likely to be decisive in this conflict. Instead, it is crucial for Kyiv to possess a range of equipment and sufficient quantities to effectively counter Russian actions.

Russia’s ongoing summer offensive is challenged by poorly trained troops, logistical hurdles, and inadequate intelligence, in addition to its own resource shortages. This remains a war of attrition, with the significant advances seen by both sides in 2022 now a distant memory. Although Ukraine successfully pushed Russian forces back from Sumy in late June, Russia continues to make gradual progress in the southwestern Zaporizhzhia region.

European Commission President Ursula von der Leyen urged enhanced European efforts to support Ukraine’s defense on Friday.

While NATO’s European members agreed last week to boost defense spending and expand their industrial base, these measures will require time to yield results. Even as European alternatives like the French Foudre MLRS rocket—potential replacements for HIMARS—are under development, support from Washington remains vital for Ukraine’s defense efforts.
