The Kh-55/Kh-555 family is a Soviet-designed, Raduga-built air-launched cruise missile line used by Soviet and Russian strategic aviation. The original Kh-55 and Kh-55SM were nuclear-armed standoff weapons, while the Kh-555 is a conventional derivative with improved accuracy and reported range up to about 3,500 km. Russian Tu-95MS and Tu-160 bombers have used the family in long-range strike packages in Ukraine and Syria.
Russian forces have used Kh-101/Kh-555/Kh-55 air-launched cruise missiles from strategic bombers in long-range strike packages against Ukrainian energy, infrastructure, industrial, and military targets, with Ukrainian reporting continuing to identify the family in 2026 attacks.
Role detailsRussian long-range aviation used Kh-555 conventional air-launched cruise missiles from strategic bombers during November 2015 strikes in Syria, including attacks associated with the Russian intervention on the Syrian government side.
Role detailsOpen missile references identify Russian strategic bombers as the carrier aircraft for the Kh-55/Kh-555 family.

The Kh-55/Kh-555 family covers several closely related air-launched cruise missiles whose public conflict reporting often appears as mixed Kh-101/Kh-555/Kh-55 launch packages rather than as single-variant strike accounts.
| Topic | Documented context | Primary support |
|---|---|---|
| Designation split | The original Kh-55 and Kh-55SM are nuclear standoff missiles; the Kh-555 is the conventional derivative used in Russian long-range aviation strike reporting. | CSIS Missile Threat; Russian Strategic Nuclear Forces |
| Carrier aircraft | CSIS lists Tu-95MS, Tu-142M, and Tu-160 bomber variants as launch platforms for the family. | CSIS Missile Threat |
| Ukraine identification limits | Ukrainian and NGO munition references sometimes group Kh-55, Kh-55SM, Kh-555, and modified or reassembled examples together, so conflict notes use the family grouping when reports do the same. | Ukraine Ministry of Defence; Open Source Munitions Portal |
