Ukraine has publicly displayed what appears to be the long-range version of its R-360 Neptune cruise missile for the first time, according to an analysis by Defense Express.

The extended-range variant, unofficially known as “Long Neptune,” was featured in a video released on the state weapons portal “Zbroya” on Ukraine’s Independence Day, 24 August.

The “Zbroya” portal, which published the video, serves as a unified platform for state services and programs for weapons manufacturers and acts as a brand for Ukrainian defense products. The portal was originally created by the Ministry of Strategic Industries, which transferred its responsibilities to the Ministry of Defense on 21 July 2025.

The missile stands out immediately. X-shaped folding wings. No other Ukrainian weapon matches that profile, Defense Express points out. The video doesn’t name the weapon, but the visual signature tells the story.

This “Long Neptune” has reportedly been hitting targets 1000 km (621 miles) away since March 2025—double the range of the original anti-ship version. Development started in November 2023, yet no official images surfaced until Ukraine’s Independence Day.

Defense Express analyzed the missile’s dimensions by comparing it to the original anti-ship R-360 Neptune. Using the tail section as a reference point, the publication estimates the “Long Neptune” measures over six meters in length without its booster, making it approximately 1.5 meters longer than the standard version.

The analysis suggests the missile’s central fuselage has been enlarged from 38 centimeters to approximately 50 centimeters in diameter to accommodate additional fuel capacity. The wing and tail surfaces have also been expanded to compensate for increased takeoff weight.

Here’s the catch: the launch footage in the video dates back to 2018-2020 coastal tests, not recent operations. Ukraine revealed the missile’s existence without showing current capabilities. No official specifications exist for the long-range variant. Even the warhead weight remains classified, though the original Neptune carried 150 kilograms of explosives.

If Defense Express correctly identified the weapon, and if it’s been operational since March as reported, Russian forces already know what it looks like. The visual reveal changes nothing operationally.
