US software upgrade could let Ukraine fire ERAM missiles from F‑16s within weeks

U.S. officials are considering a software modification for Ukrainian‑operated F‑16 fighter jets that would enable the integration of Extended Range Attack Munition (ERAM) missiles. The 3,350‑round stock, with a range of about 500 km and strong resistance to electronic jamming, could allow Ukrainian pilots to strike high‑value Russian targets such as mobile launchers, command centres and ammunition depots far behind the front line. The upgrade would bypass the current restriction that limits ERAM use to older Soviet‑era aircraft and would let pilots receive real‑time coordinates from reconnaissance drones.

Ukraine’s air‑defence shortfall is acute: it lacks sufficient Patriot systems and PAC‑3 interceptors needed to counter the growing frequency of Russian Iskander, RM‑48U and Zircon ballistic missiles. Ukrainian officials have repeatedly urged Washington and European allies to accelerate delivery of Patriot batteries, while also seeking long‑range strike weapons such as ATACMS, Taurus, and Storm Shadow/SCALP. Analysts say that, although a licensed domestic production of Patriot missiles is a longer‑term solution, the ERAM integration could provide a near‑term capability to neutralise Russian launchers before they fire.
