    The US National Nuclear Security Administration (NNSA) has moved one step closer to producing the B61-12 nuclear bomb by clearing it for the production engineering phase on Tuesday.

    MOSCOW (Sputnik) – This will be the weapon's final development phase, which precedes production. The previous development engineering phase lasted for four years.

    The Russian president’s spokesman Dmitry Peskov responded to the developments by making a cautious promise to refer the "necessary estimates" to specialists who will assess if the Pentagon’s new bomb posed a threat to the global nuclear balance.

    Russian military experts talked to RIA Novosti about whether Russia could stand up to this challenge and what options were available.

    Iskander response

    Russia should move fast to counter the US plan of bringing back into service an upgraded B61-12 nuclear bomb, Russian military science professor Konstantin Sivkov said Tuesday.

    "They are not rebuilding the bomb, but rather refurbishing its components and giving the shell more aerodynamic advantage. This won't take long," Sivkov, the president at the Academy of Geopolitical Problems, said.

    According to the US nuclear security authority, the bomb will have both its nuclear and non-nuclear components upgraded to extend its service life while improving safety and reliability.

    "The only counter-measure left to Russia is to create a nuclear warhead for the Iskander missile system," Sivkov said, referring to ballistic missile complexes that currently carry a range of conventional warheads.

    The NNSA plans the first production unit of the bomb for fiscal year 2020, which will be followed by full-scale production. NNSA Administrator Lt. Gen. Frank Klotz said the upgrade would add at least 20 years to the bomb’s service life.

    Threat assessment

    The precision-guided B61-12 could land within just a few feet from its target, Sivkov said. Combined with its bunker-busting capability, it is well-suited for preemptive nuclear strikes against an opponent’s command and control centers.

    "The production of these bombs will significantly augment US Air Force’s ability to carry out so-called decapitation strikes, which are strikes against our most-protected strategic command centers. Their previous modifications are stationed in Europe, and the US will undoubtedly send the upgraded version there too," he predicted.

    Igor Korotchenko, a member of the Russian Defense Ministry’s civic council and editor-in-chief at the Natsionalnaya Oborona ("National Defense") magazine, agreed that the upgraded nuclear bomb looked set to fill NATO’s nuclear arms depots across Europe.

    "This possibility has been taken into account by Russia’s political and military leadership… The question is what targets and goals the NATO alliance has in mind," he said, adding that stockpiling B61-12 bombs in NATO member states on Russian border meant they could be used in a conflict against Russia.

    Nuclear parity

    Vladimir Batyuk, the head of the Center for Military and Political Research at the Russian Academy of Sciences, disagreed, saying that the United States was more interested in preserving nuclear parity with Russia.

    "The United States is not the only country modernizing its arsenal. Russia is doing it too. But I believe the United States is willing to preserve strategic nuclear parity with Russia, which underlies the global strategic stability," he noted.

    US Secretary of Energy Ernest Moniz was quoted by the NNSA as saying that the B61-12 warhead life extension program would actually downsize the US nuclear stockpile. The bomb’s entry into service will allow the Pentagon to retire the B83-1, the last megaton-class weapon, while maintaining the US nuclear deterrent.

    Batyuk emphasized that both US and Russian military experts were more concerned about lack of dialogue on strategic arms reduction, after talks on renewing the New START Treaty stalled this year.
