Answer: Russia
Notes: Russia recently announced it fired a Zircon (Tsirkon) hypersonic cruise missile at a target in the Barents Sea. Sukhoi Su-34 supersonic fighter-bombers also carried out strikes as part of drills with Belarus. The joint exercise, called Zapad (West), began on September 12 to improve military command and coordination in case of an attack on Russia or Belarus. The 3M22 Zircon, NATO code SS-N-33, is a scramjet-powered hypersonic cruise missile developed by Russia. It was first built to strike naval targets but later upgraded for land-attack missions.
