Kyiv has unveiled the updated version of its domestically produced Neptune anti-ship missile – the same missile used to sink the flagship of Russia’s Black Sea Fleet, the Moskva, in April 2022.

A full-body view of the missile appeared in a released by arms maker Zbroya for Ukraine’s Independence Day on Sunday, shown alongside other domestically produced weapons such as Bohdana howitzers and naval drones.

As noted by defense outlet Militarnyi, the missile shown in the video has a larger body, which would explain the updated missile’s stated range of 1,000 km (621 miles), and likely a larger warhead.

In March 2025, President Volodymyr Zelensky said the upgraded version can strike targets up to 1,000 km away – a jump from the 300 km (186 miles) range listed in a 2020 brochure for the original model.

The upgraded missile was presumably used in a Ukrainian strike on the Russian naval port of Novorossiysk in May, covering a distance of over 750 km (466 miles) – one of the longest-range conventional missile strikes by Kyiv since Russia’s 2022 invasion.

Militarnyi suggests the new weapon might have accommodated a warhead containing more explosives or a hardened penetrator, or a new guidance system. Update plans in 2023 included an infrared sensor or homing system for the terminal phase of flight.

At the time, plans were also made to increase the warhead payload from 150 kg (331 lbs) to 350 kg (794 lbs), though the final payload on the upgraded version remains unspecified.

The fins on the upgraded missile also appear to be larger, which would add range capability or provide more maneuverability in-flight.

While the Neptune was initially designed as an anti-ship missile, the upgrade plans suggest it was later adopted for land-based surface-to-surface strikes.

The unveiling of the upgraded missile coincides with Zelensky’s remark that Ukraine now possesses its own long-range weaponry, overcoming earlier deadlocks caused by donor-imposed targeting restrictions on longer-range Western missiles, i.e., not allowing their systems to be used on targets in Russia proper.

3,000 km (1,864 miles) range.

Its maker has claimed it outperforms the US-made Tomahawk, with current production reportedly at about one missile per day.
