various hydraulic structures in Kryvyi Rih. This caused the water level of the Inhulets river to rise sharply. Previously it was reported that Kh-22 missiles had been used. The UK Ministry of Defence said in November 2022 that it appeared that Russian forces, due to very much depleted weapons stores, were firing old AS-15 Kent cruise missiles with the nuclear warheads apparently replaced by inert ballast, hoping merely to distract Ukrainian air defenses. However the missiles can still pose a serious risk due to their kinetic energy and any unspent fuel left in the missile that might explode. Variants Kh-55 (NATO "Kent-A", RKV-500A, Izdeliye 120) - original model with 2,500 km range. Kh-55-OK - with optical guidance. Kh-55SM (NATO "Kent-B", RKV-500B, Izdeliye 121) - with extra fuel tanks to extend range to 3000 km. Kh-101/102 (Izdeliye 111) - developed as a stealthy replacement for the Kh-55SM in the late 1990s, the Kh-101 has a conventional warhead and the Kh-102 is thermonuclear. This missile weighs some 2,200 - 2,400 kg, the weight of warhead is 400–450 kg. According to reports, the Kh-101 has a maximum range of 4500–5500 km and a variable flight profile at altitudes ranging from 30 – 70 m to 6000 m, a cruising speed of 190–200 m/s and a maximum speed of 250–270 m/s. The missile is equipped with an electro-optical system for correcting the flight trajectory and with a TV guidance system for terminal guidance. Its official range is 4,500 km or 3,000 km with a conventional payload. It is re-targetable. The missiles are expected to be accurate within 10–20 m CEP. They are expected to be in service in required numbers by 2023. The new missile complex has been successfully tested and in recent years put into series production to equip modernized Tu-160 and Tu-95MSM bombers. Kh-65SE - tactical version announced in 1992 with 410 kg conventional warhead and restricted to the 600 km range limit (expired on 2.8.2019) of the INF treaty. Kh-55/65SD (средней дальности Srednei Dalnosti - "Medium Range") - 300 km range conventional version announced in 1995, possibly for export. Shared components with the Kh-101, range reportedly increased to 600 km with a high-altitude approach, but the Kh-SD was apparently shelved in 2001. An alternative active radar seeker was proposed for anti-shipping use. Kh-555 (NATO "Kent-C", Kh-55SE, Kh-55Sh) - conventionally armed version with an improved guidance system and warhead. It became operational
