Ukraine is believed to have produced no more than a dozen «Dlinny Neptun» missiles. This assessment was voiced by retired Major General Vladimir Popov, an honored military pilot of Russia, who stressed that it is far too early to speak of large-scale production of such weapons.

Popov explained that the missile could have undergone a modernization process and even reached the stage of trial production. However, he doubted that Ukraine was capable of establishing a full-fledged serial output. According to his estimate, the country may possess only about ten of these missiles, perhaps slightly more.

The general also pointed to the specific character of Ukraine’s defense industry. He noted that most of its weaponry is assembled from components supplied by Western countries. These parts, once received, are rebranded domestically — given markings, the national trident symbol, and serial numbers. Yet, in Popov’s view, organizing a comprehensive production line and presenting it as a major achievement remains beyond Kyiv’s current capabilities.

Earlier, media outlets reported that Kyiv showcased a new version of the «Dlinny Neptun» missile, advertised with a strike range of up to 1,000 kilometers. According to those reports, development allegedly began in November 2023, with the first tests taking place in March 2025.
