OK, let’s play Global Thermonuclear War, Seventies style.
Round one. The evil Russians launch a saturation strike to take out American silos in the northern half of the Great Plains. Somewhere in the neighborhood of 1500 missiles with one to eight warheads each, probably a total of 5000 warheads. Eighteen minutes later, half of these are taken out by the counter battery explosion of twenty five hundred or so high altitude low yield anti aircraft nuclear weapons launched by NATO. Simultaneously, six or seven hundred warheads are launched from the silos felt to be most at risk, and these are targeted to interrupt second round nuclear battery fire from the Warsaw Pact.
OK, end of round one, half an hour into the war, and we have about three thousand nuclear detonations, mostly in mid air, some in the Great Plains of the US, and a bunch in the air over the poles, and over western and eastern Europe. Not much damage to civilian targets yet, but lots of incidental fallout drifting with the wind. (Even the ones that got taken out contribute to the total radiation as their warheads are disrupted without going nuke.) There are currently a few hundred warheads flying, targeted on command and control facilities on both sides. (These are much nearer to the civilian areas, in most cases.)
Round Two: Second Strike is launched by both sides, the targeting is flexible, and includes known deployment areas of both nuclear and conventional force concentrations. Probably a thousand missiles, fifteen hundred to three thousand warheads. Naval targets are targeted as well. Port facilities are saturation bombed, as are critical rail junctions. Ports and rail junctions are all near civilian targets. Large numbers of these missiles are taken out by counter fire, as a sustained cloud of nuclear explosions is maintained for the entire first hour after round one. An hour and a half has gone by, and the first and second strike capability of both sides is either expended, or destroyed. Ten thousand nuclear explosions so far, and half that many disrupted warheads adding their plutonium to the mix.
Round three: Naval engagement takes place, with all suspected locations of enemy ships being hit with low yield nuclear strikes, and known targets with multiple strikes. Submarines are all on mission, but not taking part in active fire, unless they have already expended their nuclear weapons. (Not likely, at this point.) Boomers go deep, and await their mission. Hours pass, now, and manned bombers begin to arrive at mission targets. Timing is critical, in order to take advantage of ionic disturbance from prior nuclear detonations, and avoid radar identification. Hard targets, and suspected withdrawal rally points are hit with gravity bombs, very large yields, and probably another three thousand warheads, but a yield total more than all the previous detonations. Civilian areas are now indistinguishable from military targets.
Strategic assets are now committed, expended, or destroyed. Most of the remaining assets are conventional forces with tactical nuclear capability. These military units are primarily mobile, and are actively seeking to engage the most dangerous of the enemy assets. Infrastructure, whether civilian, or military is the primary asset remaining to both sides, and small scale nuclear weapons will be targeted on the most valuable ones, probably another five thousand warheads, most of which will now be able to reach their targets. At this point, command decision will determine whether living civilian populations constitute strategic assets.
Weeks will pass, as the rate of nuclear strikes gradually decreases. Eventually one side will have established it’s ability to continue military operations without constraint from opposing forces. At that time the US has a plan. Remember those boomers that “Went deep, to await mission time?” Well, there is “Operation Spoilsport” to be considered. Three hundred to a thousand one to ten megaton warheads can be targeted on the government of the surviving enemy countries, and delivered without opposition. Whatever surviving intelligence capability is able to do so will be designating targeting scenarios already planned, and safely on board the surviving submarines.
Civilization is in ruins, over most of the Northern Hemisphere. The exact geographic characteristics that make a place conducive to the establishment of organized societies make them prominent military targets. Heavy industry is obliterated, as are rail distribution and port facilities. Civil infrastructure is disconnected at every major point of intersection. Humans will survive. But the nature of the new social system cannot be predicted. Radiation poisoning will be a regular feature in whatever system evolves. Cancer will be endemic. Multiple instances of similar plans to our own “Operation Spoilsport” will be an ongoing threat to world stability.
