Ukraine has publicly revealed a new long-range version of its domestically developed cruise missile, known unofficially as the “Long Neptune.”
The missile, with a reported range of 1,000 kilometers, was shown for the first time, Defense Express reported.
No official specifications have been released, but earlier statements indicated the missile is designed to strike land-based targets at extended distances.
According to Defense Express, the missile has already been used in combat operations since March, meaning its appearance is unlikely to be a surprise to Russian forces.
Visual comparisons suggest the new missile differs considerably from its predecessor, the R-360 anti-ship version. The tail section, which houses the engine, appears largely unchanged and can be used as a reference point for scale. Based on this, analysts estimate the “Long Neptune” measures over six meters in length without its booster—approximately 1.5 meters longer than the original R-360.
The central fuselage has also been enlarged, with its diameter increased to about 50 centimeters from the earlier 38 centimeters. The report noted this change likely allows for additional fuel capacity, extending the missile’s operational range. At the same time, the nose cone retains the same diameter, while the wings and tail surfaces have been expanded to support a heavier launch weight.
The weight of the warhead remains unknown. The earlier R-360 carried a 150-kilogram warhead, but Defence Express said no details have been provided about the payload of the long-range version.
The Russian Ministry of Defense has repeatedly claimed that Ukraine has employed Neptune missiles to strike both occupied territories and targets deep inside Russian territory.
The unveiling comes as Ukraine continues to expand its domestic missile development despite the pressures of war.
