R-360 Neptune / Long Neptune
The R-360 Neptune is a Ukrainian truck-launched cruise missile developed by State Kyiv Design Bureau Luch as a coastal anti-ship system and later adapted into longer-range land-attack variants. In the Russia-Ukraine War it became one of Ukraine's most visible domestic precision-strike weapons, first for Black Sea targets such as Moskva and later through the Long Neptune / Neptune-D family reported with a 1,000 km reach.

Related Weapon Systems
HarpoonCoastal and anti-ship cruise missile systemHarpoon is a U.S.-origin all-weather anti-ship cruise missile family built around active radar terminal homing and sea-skimming flight. In the Russia-Ukraine War, Ukraine received land-based Harpoon coastal defense systems and adapted truck-launched RGM-84 missiles to threaten Russian surface ships operating near the Black Sea coast.
KalibrSea-launched land-attack cruise missile familyKalibr is a Russian family of ship- and submarine-launched cruise missiles, including the 3M-14 land-attack variant known to NATO as SS-N-30A. Its long range, naval basing, and conventional or reported nuclear payload options make it a central Russian Navy strike weapon, and Russian forces have repeatedly used Kalibr missiles in the Russia-Ukraine War for deep strikes against Ukrainian targets.
Kh-59Air-launched tactical cruise missileThe Kh-59 Ovod is a Soviet/Russian air-launched tactical cruise missile family developed by Raduga for standoff strikes from tactical aircraft. Later Kh-59M, Kh-59MK, Kh-59MK2, and Kh-59MKM variants added turbojet propulsion, larger warheads, anti-ship or land-attack guidance options, and longer range. Russia has used Kh-59-series guided air-launched missiles during the Russia-Ukraine War as part of mixed missile and drone attacks.
P-800 OniksSupersonic anti-ship cruise missileThe P-800 Oniks is a Russian supersonic anti-ship cruise missile, also associated with the Yakhont export variant and Bastion coastal launch systems. Designed for high-speed attacks against naval targets, it has also been used by Russia as a land-attack weapon against southern Ukraine, where its speed and low terminal flight profile complicate interception.
9K720 IskanderRoad-mobile tactical ballistic and cruise missile systemThe 9K720 Iskander is a Russian road-mobile tactical missile system that launches short-range ballistic missiles and, in Iskander-K configuration, ground-launched cruise missiles. In the Russia-Ukraine War it has served as one of Russia's principal precision-strike systems for attacks beyond the immediate front line.
Kh-101Air-launched cruise missileThe Kh-101 is a Russian conventional air-launched cruise missile in the Kh-101/Kh-102 family, designed for long-range standoff attacks from strategic bombers. Its low-altitude flight profile, turbofan propulsion, satellite/inertial navigation, and terminal guidance make it one of Russia's principal long-range strike weapons in the Russia-Ukraine War.Sources
