 Ukraine begins production of missiles that can hit Russian territory. Many of the missiles Russia has been using to strike Kiev and other cities, along with Ukrainian infrastructure, were originally designed and built in Ukraine. According to Kiev, post-media outlet Elements of the Kh-55 family of cruise missiles were designed by Yusnoi State Design Office in Nipro and, while the complete missile was developed by Moscow's MKB-Raduga Design Bureau, the missiles went into serial production in the 1980s at the Kharkiv Aviation Plant, with engines provided by Motor Seek. It is noted that Ukraine holds all the original technical details of the Kh-55 and its derivatives, as well as probable access to documentation relating to Retters Kh-101 and caliber missiles. In developing new missiles, it will use this information as the basis for two new missiles, the Caution Cruise Missile and the Grom 2 Vertically Launched Tactical Missile. While the exact technical details of the missiles are confidential, it's believed that the Caution will be designed for air, ground and ship launch, and primarily used to attack static land targets using known geolocated coordinates. According to the Kiev Post, based on open-source Schemic Drawings released by Ukro Boronexport, it will have a 480 kg warhead containing high explosive penetrating sub munitions, although a conventional high explosive fragmentation warhead may also be available. The missile will use a solid fuel rocket booster to launch and bring it to cruising speed when a turbojet engine will power it through the rest of the flight. The turbojet, which is a development of the original Kh-55's Soyuz R95-300 motor, is manufactured by MotorSick with the new designation of MS-400. The original 2014 design was for a smaller missile with a range of around 300 km. It seems that the newer version will be much larger, weighing around 1300 kg and, when ground launched, with a range of around 700 km. The Caution is expected to use a guidance system that combines inertial and GPS navigation. Fewer details are known about the Grom 2 Tactical Missile. It will carry the same warhead as the Caution, but on a much larger missile with a weight of around 3000 kg. The maximum range is currently believed to be around 500 km.
