The Secret of 6 Meters: Ukraine Reveals the Conqueror of the Fronts

Over the course of the war, Ukraine has transformed into a major weapons manufacturing hub, focusing on both short- and long-range capabilities, including drones and missiles.

In the latest development, Ukraine recently unveiled the specifications of its upgraded locally produced “Neptune” missile. The new weapon is capable of striking targets up to 1,000 kilometers away, with a 260-kilogram warhead.

Kyiv has rapidly expanded its domestic defense production amid escalating Russian attacks, now producing approximately 60% of the weapons used on its fronts, according to Ukrainian media reports.

The enhanced missile, designated “RK-360L” and part of the Neptune-D system, represents a significant leap compared to the original “RK-360 Neptune,” which had a range of only 280 kilometers.

The warhead has been enlarged from 150 kilograms to 260 kilograms, according to Ukrainian media citing the government defense portal Zbroya.

The new missile measures six meters in length without a booster, approximately 1.5 meters longer than its predecessor, with a diameter of 50 centimeters compared to 38 centimeters for the previous model.

Its design allows for modifications, such as reducing the fuel tank to increase the warhead capacity.

Long-Range Strike

The upgraded weapon is believed to have been deployed for the first time on the battlefield in May, during an attack on the Russian naval port of Novorossiysk, more than 750 kilometers away, marking one of the longest conventional strikes carried out by Ukraine since the conflict began in 2022.

The Neptune missile was originally deployed in 2021 as an anti-ship cruise missile with a 150-kilogram warhead and a range of approximately 300 kilometers.

It gained international attention in April 2022 when it sank the Moskva, Russia’s flagship in the Black Sea.
