 Ukraine is re-engineering a 36-foot-long Soviet-era missile system to strike inside Russia. Ukraine appears to be using a large Soviet-era missile system to strike inside Russia, according to the UK Ministry of Defence. Along with drones, regularly hitting Moscow, there have been increasing reports of A5 Gammon missiles striking Russia. The department noted in an intelligence update insider media outlet reports. The weapon also called the S-200 surface-to-air missile system weighs 7.5 tonnes and is 36 feet long. Ukraine has retired the weapon from its air defence role and is now instead using it as a ground-attack ballistic missile, the department said. Forbes reported in July that Kyiv might be repurposing the obsolete weapons for ground attacks to replace its diminishing stockpile of Tochka ballistic missiles. Russian news agency TASS reported that Kyiv tried to strike Crimea with a re-equipped S-200. Kyiv has not claimed responsibility for the attacks on Russian territory, but several officials have implied support and S-200 can hit targets as far away as 190 miles and as high as 130,000 feet in the air defence role and this range could be even further in a ground-attack role, Forbes said. Strikes inside Russian territory are strategically significant as President Vladimir Putin likely invaded Ukraine, believing it would have little effect on Russian's the UK Defence Ministry noted. Because of the rising threats, the leadership of Russia's aerospace forces is likely under intense pressure to improve air defences over western Russia, it said.
