The Trump administration is planning to redirect proximity fuses intended for the 70mm Advanced Precision Kill Weapon System (APKWS) rockets, initially designated for Ukraine, to US Air Force units in the Middle East.
While the allocated funds, part of the Biden Administration’s $3.85 billion Ukraine Security Assistance Initiative, have already been used, the equipment procured will continue to be delivered until the end of 2026. The APKWS missiles are a component of the L3Harris VAMPIRE counter-drone system, over thirty of which have been supplied to Ukraine to bolster its defense against Russian drone threats.
The Wall Street Journal, which first reported this policy change, stated that the Pentagon informed the Senate Armed Services Committee that the fuses are needed under a “Secretary of Defense Identified Urgent Issue” directive, allowing US Air Force units stationed in the Middle East to prepare for a potential confrontation with Iran and Houthi militants in Yemen. The Air Force has integrated APKWS rockets as a cost-effective alternative to Sidewinder and AMRAAM air-to-air missiles for use against unmanned aerial vehicles (UAVs) by F-16 and F-15E fighter aircraft.
The decision highlights growing pressure from the Trump Administration for European nations to take on a greater share of future military aid to Ukraine. In March, the US temporarily halted military shipments to Ukraine, resuming them only after Ukrainian officials accepted a truce plan during discussions in Jeddah on March 11. Furthermore, no new military aid packages for Ukraine have been approved since President Trump began his second term in January 2025.
This pressure was perhaps further underscored by Defense Secretary Pete Hegseth’s absence from Wednesday’s Ramstein Ukraine Defense Contact Group (UDCG) meeting at NATO headquarters. This was the first instance since the start of the full-scale war that the US Defense Secretary was not in attendance.
The timing of this policy shift is particularly sensitive. Following Ukraine’s Spiderweb attack on Russian strategic airfields on June 1, Russian President Vladimir Putin reportedly warned President Trump in a phone call on June 4 that a forceful response would follow, likely resulting in an escalation of drone and missile attacks on Ukrainian cities and military positions.
On June 1, Russia carried out its most extensive drone offensive since the onset of the full-scale invasion, deploying a wave of 472 attack drones. President Volodymyr Zelensky stated on June 4 that, since the beginning of 2025, Russia has launched more than 20,000 drones against Ukraine.
Furthermore, a source in Ukraine’s Main Directorate of Intelligence (HUR) told the Kyiv Independent earlier this week that Russia has ramped up the production of the Shahed 136 (Russian designation Geran-2) one-way attack drones, and will soon be able to deploy more than 500 a night to attack Ukraine.
In response, President Zelensky has urged allies to increase investments in domestic arms production and provide “faster deliveries” of additional air defense systems, specifically Patriot missiles, to counter intensifying Russian aerial offensives.
