MBDA to Help Ukraine Develop New Neptune-2 Cruise Missile

Europe’s leading missile manufacturer MBDA has signed a letter of intent with Ukraine’s LUCH Design Bureau to jointly develop the next-generation Neptune-2 cruise missile. Announced on June 16, 2026, the deal marks one of the most concrete steps yet in Ukraine’s effort to deepen its long-range strike capability.

MBDA’s commitment

MBDA said it would provide Ukraine with “technology, expertise and international partnerships,” adding that Neptune-2 would feature innovative characteristics that “extend deep-strike capabilities.” LUCH Design Bureau, which previously worked alongside MBDA’s Storm Shadow and SCALP-EG cruise missiles — weapons that have been used effectively against Russian targets by combat aircraft — is now forming a direct partnership with the company.

What sets Neptune-2 apart

The original Neptune gained international recognition in 2022 after sinking the Russian Black Sea Fleet flagship cruiser Moskva. Neptune-2 substantially upgrades that base design: greater fuel capacity extends range to up to 1,000 kilometers, while warhead weight increases to 260 kilograms. The missile will measure 6 meters in length with a 50-centimeter body diameter.

Why it matters

Ukraine has relied on Western allied support since the start of the war to build its own deep-strike capability. Direct involvement from an established European defense firm like MBDA in technology transfer and joint development has the potential to accelerate the maturation of Ukraine’s domestic missile industry — while giving Europe’s defense sector a direct channel to learn from Ukraine’s wartime combat experience.

Regional and NATO context

Any increase in long-range cruise missile capability carries direct implications for the Black Sea balance of power. With Türkiye at the center of Black Sea maritime security architecture, an expanded Ukrainian missile range is being viewed as a development that feeds directly into deterrence calculations along NATO’s eastern and southern flanks.

What’s next

The letter of intent does not yet constitute a binding production agreement; technical details and intellectual-property arrangements between the parties remain to be finalized. No official timeline for Neptune-2 reaching operational capability has been announced.
