…range is not the distinguishing feature of the Oreshnik just as hypersonic speed ( in this case 10 Mach) is not its distinguishing feature. Its fuel and launchers are the distinguishing feature.
The Sarmat is a liquid fuel missile that is launched from silos on land. These silos are hardened so as to protect against even a direct hit by a nuclear weapon, but their location is surely known to the adversary. The Oreshnik, by contrast, is a solid fuel rocket that is launched from mobile launchers that can be moved around and hidden under camouflage as required. Therefore, its possible destruction in a preemptive first strike by some adversary is far more problematic.
In the present-day context of the war in Ukraine, even without explosives on board, the Oreshnik has the force at impact to destroy everything below it to a depth of 200 meters. This means that the bunkers used in Kiev and elsewhere in Ukraine by US and NATO officers coordinating the military operations, and also the bunkers now protecting Mr. Zelensky and his war criminal confederates are entirely vulnerable to Russian attack at the time of Moscow’s choosing.
As regards Western Europe, the generally quoted warning time from launch of the Oreshnik in mainland Russia to impact in Berlin is 11 minutes. However, if launched from the Russian enclave of Kaliningrad, the flight time is reduced to about 4 minutes. This has surely unnerved Mr. Scholz and his little band of would-be warriors in Germany. Sooner or later the same arithmetic will be understood by Cold Warriors in Paris and Brussels. None of them will know what hit them if the Russians go on the offensive and attack Europe with the Oreshnik in response to the various provocations surely being hatched in NATO meetings this week.
