The nuclear-powered cruise missile is not a new idea.

The idea of the nuclear-powered missiles and rockets is not new and during the Cold War, the United States military created the idea of using the nuclear reactor in the high-speed cruise missile. A benefit for that missile was that it could fly even years with extremely high speed, but the problem was pollution, what denied the testing of that weapon. That missile could fly across the earth by using the nuclear reactor, but the project canceled because the pollution was the problem. That attempt was called as "PROJECT PLUTO".


This nuclear-powered ramjet engine was very simple. The burning fuel was replaced with the nuclear reactor, what would give an extremely powerful punch for that weapon, and the idea was to make supersonic cruise missile, what was full of sub-warheads, and what was capable to destroy multiple targets in the Soviet Union. The pollution of that engine was extremely high, and the radioactive fallout would pollute large areas in the route of this missile. The nuclear ramjet bases the reactor, what would change the output power simultaneously, and that would give the pressure waves in the motor, what would push this weapon forward.


The cooling system bases that the high-speed air would transfer the heat away from the reactor. The production of this weapon is very difficult because it leaves the highly radioactive components behind it, and that's why the test flights would be very difficult. And the radioactive material would be delivered to the large areas. This technology is of course very interesting, and now Russians are working with this kind of project. So there is nothing new under the sun.

About Russian hypersonic missile and strengths and weaknesses about hypersonic cruise missiles

(Picture I)

Kimmo Huosionmaa

Russia has said, that it would have the new hypersonic missile, what can knock out any U.S Carrier from the sea. This concept is not actually very new, and the beginning of this weapon is in the early 90's when the Soviet Union collapsed. In that time engineers worked with the new type of weapon, what based on the ramjet-propellant hybrid missile, that could avoid U.S air defense. Hypersonic missiles have many strangenesses but also weaknesses, and one of those weaknesses is that those missiles cannot make many curves, what makes probably possible to calculate their flight route and the target, and the heating of the nose can also allow targeting the missile with infrared systems. This can help the target to predict the attack, and send the anti-aircraft missiles against those hypersonic weapons.


The weapon was meant for a shoot to ballistic trajectory by using conventional ICBM missile like SS-19 or it's the first stage, and then the missile would dive in the atmosphere. After or during the dive, the fuel would be injected to the ramjet engine, and then the cruise missile could start to fly to its target in the speed of Mach 6 or more, and that very high speed would make the defense against that missile very difficult, and those missiles would be very big threat for any target in enemy territory.


Those cruise missiles would seem the little bit like SS-N-21, but they must be more aerodynamic than SS-N-21. Those missiles would be devastating even without the warhead, and if they would attack against carrier fleet, would the level of kinetic energy be very high, if that kind of missile hits the ship. But of course, that kind of cruise missiles can carry the conventional or nuclear warhead. The problem of the warhead is that very high speed of the weapon would make the timing of detonator quite difficult, because if the warhead detonates in the different time, would the armored nuclear command bunkers survive the attack.  The modern computer technology makes those missiles more deadly than ever before.


Modern computers allow the missile to change it's course and speed all the time, and also image identification system allows them to attack sharply than ever before. Those systems bases that the photograph of the target is installed in the memory of the computer, and then the camera takes the picture, what is compiling with the picture that is saved in the memory of the computer. When those pictures are perfectly in one on the other, the weapon attack straight to the target. Hypersonic cruise missiles are very difficult for defenders because they are extremely high-speed targets, what can fly in low level.


There is, of course, one weakness about those weapons. That is that their nose would be heated in very high temperature and that infrared signature can be used to aim anti-aircraft weapons to those targets. The most effective weapons, what can be used against those hypersonic cruise missiles could be DEW:s (Directed Energy Weapons) like lasers, what can aim to target by using infrared cameras. And if there would be creating the hole in the nose of that missile, would that cause the situation, that the hypersonic weapon would be destroyed before it hits the target. But that needs the direct hit to the missile. The speed of hypersonic cruise missile causes, that if any projectile hits it, by flying straight to the nose of that weapon, that would destroy the hypersonic missile by very high-level impact power. And those high-speed missiles cannot turn very tight curves, what could be possible to calculate the point, where that missile would fly, what might make defense possible.

The “Sarmat” missile

"Sarmat" missile
(Picture 1)

Kimmo Huosionmaa

“Sarmat” is nothing like any other ICBM. This weapon is mobilized version of the SS-18 (R36) missile, what was the largest thermonuclear weapon in the world. It has more warheads and capacity to raise those weapons in the orbital trajectory. This weapon is actually FOBS (Fractional Orbital Bombardment System”, what is tested by the Soviet Union and the possible USA in 1960’s. Those weapons have huge weapons load, what makes them very terrible. In those weapons is MIRV (Multiple Independently Targeted Reentry Vehicles) what can be targeted to same target or different places around the world. This kind of FOBS-weapons can send to orbital trajectory weeks or even years before shooting order.


They can play normal satellites, and when the order of action comes, the satellite would start to drop nuclear weapons to their targets. This eliminates the way to locate those weapons by using its communication signals as the tip. If those weapons could be located, there is the way to target them with high-altitude ASAT systems. The thing why those nuclear weapons would not locate very easily is that they can work with the normal satellites. And when those weapons are needed, the programs of the computers must only change, what makes those satellites the ultimate killers.


Those warheads are actually independently targeted and they can use like carpets, where all warheads would be put in the same place. But those FOBS weapons have the very frightened capacity, that they could be sent to the orbital trajectory, and then dropped one by one in many targets, what is separated from together. Also “Sarmat” can drop one warhead and leave other to MIRV-bus waiting for next target. Those weapons can be programmed to explode in the orbital trajectory, in the atmosphere or they can program to hit the ground in the line, and that kind of weapons can destroy even the command center of NORAD.


FOBS capacity makes that weapon so terrible. It can be used against highly mobile targets, and it can threat also U.S task fleet and submarines. Those weapons would be used with reconnaissance satellites, what are looking for “hard to find easy to kill” targets for that weapon. The capacity to use one warhead by one is because this weapon must find those highly mobile targets before it can take effect to them.
