In order to counter Russian aggression in the Black and Azov seas, the RK-360 “Neptune” was developed. State tests of the national R-360 “Neptune” missile system are ongoing successfully and effectively in Odesa region. Launches are carried out at the firing range “Alibey” of the Armed Forces of Ukraine. The main feature of the tests of the “Neptune” ground-based cruise missile system this time was the warhead firing. It is a system of ground-based cruise missiles with an anti-ship missile, designed to destroy cruiser, destroyer, frigate, corvette, landing, tank landing and transport ships, which operate both independently and as part of naval task force and landing detachments, as well as radio targets, in simple and complex meteorological conditions at any time of day and year, with active fire and electronic warfare measures of the enemy.
The missile was revealed for the first time in the exhibition “Weapons and Security 2015” which held in Kyiv. Production of advanced missile weapons takes place in cooperation with other Ukrainian enterprises, including Artem Luch GAhK, Kharkiv State Aviation Plant, «Motor Sich» (turbofan MS-400 engine), Pivdenne YuMZ PivdenMash, Lviv LORTA or other radar electronics, Vyshneve ZhMZ Vizar Kiev and others. March 22, 2016, the first tests of the Neptune missile were conducted. The tests were attended by secretary of NSDC of Ukraine Oleksandr Turchynov. In mid-2017, missiles were tested concurrently with trials of the Vilkha complex. However, unlike the Vilkha, the test results and capabilities of the “Neptune” rocket were not advertised.
On January 30, 2018, according to the press service of NSDC, the first flight tests of the Ukrainian ground-based cruise missile, which is capable of accurately hitting ground and naval targets, were successful. On August 17, 2018, the missile successfully hit a target at the range of 100 km during test fire in the southern part of Odesa oblast. 6 April, 2019, the missile was successfully tested again and hit target during tests near Odesa. 6 April, 2019, the missile was successfully tested again and hit target during tests near Odesa, according to President Petro Poroshenko’s statement. After the United States and the Russian Federation both left the INF Treaty, Ukraine announced that it was considering developing intermediate-range cruise missiles. Analysts consider an extended-range Neptune missile to be a candidate for such an effort.
Neptune is an Ukrainian cruise anti-ship missile under development by Ukroboronprom. Expected to be mounted on three platforms: ship, land and air launches. The prospective missiles will be located in transport and launch containers (TLC) with dimensions of 5,300 × 600 × 600 mm. The length of the rocket itself with an accelerator of 5,050 mm. TLC with a rocket with a cross-shaped hard wing can be placed on terrestrial, marine or air carriers. It is intended to defeat combat surface ships and transport vessels from the structure of shock groups (convoy) or moving individually with a displacement of up to 5,000 tons. The missile is based on a design of the Soviet anti-ship missile Kh-35, however Ukrainian constructors substantially improved missile range and electronic.
