 Russia faced serious failures in tests of nuclear-tipped missiles. The Russian Federation conducted unsuccessful tests of the Yars and Bulava missiles, which are carriers of nuclear weapons according to the Defence Intelligence of the Ministry of Defence of Ukraine. On November 1, 2023, the aggressor state, Russia, conducted unsuccessful tests of the Intercontinental Ballistic Missile, RS-24 Yars, which is the mainstay in the ground-based component of the strategic nuclear forces of the Russian Federation. The press service reports, the launch of Yars was carried out from the Plesetsk Cosmodrome located in the Arkhangelsk region with the target at the Kura Test Range in Kamchatka. According to intelligence data, the missile deviated from its course just as it did during the previous exercises on October 25, 2023. Likewise, the test launch from the Submarine Missile cruiser Bory of the Ballistic Missile RS-M56 Bulava on October 25, 2023 ended unsuccessfully confirming its unreliability once again, according to Defence Intelligence. Moscow also faces problems with the Navy ICBM-RS-28 Samat of silo-based deployment, which is one of the key projects in the modernization of Russia's strategic nuclear forces, Compared to the Ukrainian-manufactured ICBM-RS-20 Voyevoda, the Samat missile, which is intended to replace it, lacks any advantages in design, payload or methods of overcoming missile defence. In fact, Samat is an unfinished, imperfect and crude missile, adds intelligence. Russia also faces difficulties in its plans to enhance the air components of its strategic nuclear forces. As part of the modernization of TU-160 and TU-95MS aircraft, the Russians have the capability to refurbish 1-2 aircraft annually. The planned delivery of new strategic bombers TU-160M-2 for 2023 has been postponed to a later date, as the Russians have not been able to resume production of the new version of NK-32 engines, the Press Service notes.
