Valerii Romanenko, an aviation expert and leading researcher at the State Aviation Museum, stated this on Espreso TV."Regarding the 9M729 cruise missiles that Russia has started using, this missile is capable of carrying a nuclear warhead. And the Iskander-M is also capable of carrying a nuclear warhead. And the Kalibr is capable of carrying a nuclear warhead. And the modification of the Kh-102 missile carries a nuclear warhead. All cruise missiles are capable of carrying a nuclear warhead. What kind of missile is the 9M729 and why did the Americans react to it so strongly? In 2017, Western European intelligence tracked that the Russians had a new missile, and determined that it could fly 2,500 km. This missile is standardly included in the nomenclature of weapons of the Iskander complex," the aviation expert commented.According to him, the Iskander has three types of missiles. The first is ballistic, what we call Iskander-M. The second is Iskander-K. And this new missile is half a meter longer than the standard, an analogue of the Soviet R-500 missile, but has five times the range. Both of these missiles are analogues of the Kalibr missile."I remind you, we shot down Kalibrs in quantities of 9 out of 10 launched. That is, although this missile is new, it does not pose such a special threat. All types of cruise missiles are shot down, at least 4 out of 5, and in the best case - 9 out of 10," Romanenko noted.During a massive missile attack on October 5, Russia used a 9M729 missile against Lapaivka in the Lviv region. Its fragments were found at the impact site. Before hitting the target, it flew over 1,200 km.Ukraine's Foreign Minister Andrii Sybiha says Russia is hitting Ukraine with the 9M729 cruise missile, the very weapon whose secret development caused the U.S. to scrap the INF treaty in 2019.
