The Delta IV carries the RSM-54 Makeyev missile (Nato designation: SS-N-23 Skiff), which is reported as a “three-stage liquid propellant ballistic missile” able to attack at ranges of 5,200 miles, according to unconfirmed reports. While there is not much reliable information on the composition or lethality of the RSM-54, it is believed to be possible that it can fire nuclear warheads on multiple-re-entry vehicles.
Nuclear missiles from the Arctic region could be used as a kind of “bolt-out-of-the-blue” massive salvo nuclear attack on the United States, with the idea being to disable any U.S. ability to respond or counter-strike. Should a number of Delta IV, nuclear-armed submarines launch simultaneous nuclear attacks from the Arctic region, weapons would not have as far to travel to hit the U.S. and Canada quickly.
Pentagon Preparation
This possibility is precisely why the Pentagon works to maintain a full nuclear triad, meaning land, air, and undersea options for a nuclear attack. This is the premise of strategic deterrence: should there be any nuclear attack on the U.S., the attacker would quickly be fully eliminated in a catastrophic retaliatory second strike. Therefore, should U.S. ground-based interceptors be unable to track and intercept a large incoming salvo of nuclear missiles, nuclear armed ballistic missile submarines conducting clandestine reconnaissance missions could guarantee complete annihilation of the attacker. This is kind of a paradox, as perhaps it is only through the promise of total catastrophe and destruction, that there can be the assurance of peace.
