Recall the Russian press reported in advance that Grom-2019 would be a command and control CSX with live activity by RVSN, LRA, VTA, and Northern and Pacific Fleet forces and 16 ballistic and cruise missile launches.
Russian Northern and Pacific Fleet SSBNs fired SLBMs from the Barents Sea and Sea of Okhotsk to the Kura and Chizha impact areas respectively.
Video showed Delta IV-class SSBN Karelia (SS-N-23 Sineva SLBM) was the Northern Fleet shooter. An SS-N-18 Stingray was supposed to be fired, so the Pacific Fleet boat had to be one of three Delta III-class SSBNs.
Media accounts indicated Northern Fleet and Caspian Flotilla surface ships launched 3M-14 Kalibr (SS-N-30A) cruise missiles against land targets at the same time.
NVO claimed more Kalibr missiles were fired from submarines and from Pacific, Baltic, and Black Sea Fleet platforms. This should be considered unsubstantiated for now.
A mobile RS-24 Yars (SS-27 Mod 2) ICBM was fired from Plesetsk to Kura.
Iskander crews launched cruise missiles (SSC-8 or 9M729) from ranges in the Southern and Eastern MDs. The SSC-8 was the Russian system that busted the INF Treaty.
Russian TV news Pervyy kanal provided this report on Grom-2019:
Tu-95MS / Bear-H bombers fired their Kh-55 (AS-15 Kent) cruise missiles to Pemboy and Kura.
Mil.ru reiterated that Grom-2019 was intended to check the readiness of Russia’s military command and control organs and the skill of commanders and operational staffs in organizing command and control of subordinate forces. The MOD website reported all missions were fulfilled, and all missiles reached their targets and confirmed their capabilities.
With INF gone and New START (START III or what the Russians call SNV-III) approaching expiration in 2021, Grom-2019 might have been the first stratex of a post-arms control era. When were intermediate-range nuclear missiles used to such a degree in a stratex? Moscow may have tested its nuclear response and escalation in a world without a ban on systems short of truly strategic ones.
