Kh-59

Developed by Soviet designer MKB Raduga from the mid-1970s and in service with the Soviet Air Force since 1980, the Kh-59 “Ovod” (“Gadfly,” NATO designation AS-13 “Kingbolt”) is an air-launched cruise missile designed to engage defended ground and surface targets from stand-off range. The original variant was built around visual target acquisition by the launching crew in daylight and clear weather, and was fielded as a precision stand-off weapon for the Su-24M and later the Su-17M4. Serial production was handled by the Smolensk Aviation Plant and the Dubna Machine-Building Plant; current manufacturing sits inside Russia’s Tactical Missiles Corporation (KTRV).

Per publicly documented specifications, the baseline Kh-59 weighs around 930 kg, measures 5.7 m long with a 1.3 m wingspan, and carries a 320 kg cluster or shaped-charge fragmentation warhead. Flight is in two stages: a solid-fuel booster drops the missile onto its cruise profile, after which it skims at roughly 7 m above water or 100–1,000 m over land, held there by a radar altimeter. The original variant uses inertial guidance handed off to a nose-mounted television seeker that relays video back to the launch aircraft over a datalink, letting the operator steer the missile onto the target in the terminal phase; later Kh-59M, Kh-59MK and Kh-59MK2 subtypes replace the booster-plus-rocket arrangement with a turbojet for extended range (up to around 290 km in the MK2) and, in the anti-ship and land-attack MK variants, add millimeter-wave active radar homing. The MK2 has been integrated with the Su-57.

The missile is a long-standing export item: alongside Russia, China, India and Algeria have been identified as operators. It saw use in the Chechen wars and, since 2022, in the war against Ukraine, where it is routinely bracketed with the newer Kh-69 — a related stealthier cruise missile often reported together in Ukrainian air-defence tallies.

Recent OSINT around the Kh-59 is predominantly combat-reporting from the war in Ukraine, with claims from both sides to treat carefully. Ukrainian Air Force statements through August and September 2026 described Kh-59 launches against targets in Odesa and other regions, with a mix of outcomes — including one 31 August report that the missile “did not reach its target” and a 12 September log claiming two of six Kh-59/69 shot down. Russian milbloggers, including Rybar and Boris Rozhin, place Kh-59/69 strikes within a broader campaign against Ukrainian maritime logistics in Chornomorsk, Izmail and Odesa, alongside Geran loitering munitions, Oniks and Kalibr. Independent corroboration of specific hits is thinner than either side’s claims.
