In Ukraine there was a rocket "Puzati Neptune": what was noted by Western experts
And judging by the published images, created as a rocket with extended capabilities of the Basic Family P-360. The War Zone is written about it. It is noted that initially "Neptune" (P-360) was developed as an anti-ship on the basis of the Soviet X-35 with the declared range of serial samples-about 300 km.
In recent years, the version of the rocket with a combined guide system (inertial with GPS correction + IR-sensor) has been developed and optimized for ground blows, the range of which is estimated at least 360 km. Then there was a modification of "Neptune-D" with increased range-up to 1000 km. Judging by the location of the projections in front of the stabilizers, they could accommodate additional fuel tanks.
This is considered analysts, a relatively simple way to increase the range without radical processing of the body. There is another explanation. The performances contain elements of avionic and navigation, which corresponds to the internal layout of X-35-shaped structures, and the warhead is traditionally located in the nasal. However, such a version is unlikely, experts said. Increasing the range of the basic version of Neptune creates an intermediate class of weapons in the whole line.
This will reserve the long Neptune for maximum range and at the same time provide a cheaper and faster way to modernize available missiles by upgrading available ammunition. Finally, against the backdrop of supplies of British Storm Shadow and French Scalp-EG, as well as American ATACMS and a variety of long-range drones-Kamikadze, Neptune modernization gives Ukraine an additional, relatively accessible tool for strokes both for marine and for terrestrial purposes.
