Killer satellites are the new threat.

Military space applications are remarkable systems. Because. Satellites are becoming. More and more important. Many military applications. Like GPS, it requires satellite communication. And that makes satellites vital targets for defense. Things. Like reconnaissance satellites. Play. A vital role. In the target location. And this means. that ASAT(Anti-Satellite) systems are becoming. More important. The GPS satellites are objects that the enemy wants to knock out. Maybe regular killer satellites cannot harm people on the ground. But those satellites can destroy other satellites. 

The new stealthy satellites cause grey hair for defense. The same system that another participant in those projects uses for intelligence can be turned into a fractional orbital bombardment system (FOBS) in the hands of another participant. The FOBS normally means nuclear weapons. These are positioned into orbital trajectories. Internet sources mention. The FOBS is a partially orbiting system. Or a so-called sub-orbiter system. But the high-orbiting FOBS systems are also possible. The system requires only large-sized rocket boosters. 

And they can be used as the electromagnetic pulse (EMP) or as “regular” atomic weapons. Those systems can also drop things like drones or conventional explosives to their targets from an orbital trajectory. Another version. That those stealth satellites can be. Are anti-satellite weapons (ASATs). Or. So-called killer satellites. The first killer-satellite prototypes were created in the Soviet Era. The names of those projects were “Almaz”, “Istrebitel Sputnikov”, and “Terra 3”. These reseachers investigated land-based lasers and ASAT missiles. 

There is also suspicion that famous Soviet nuclear-powered Kosmos satellites like Kosmos-954, which fell to Canada, were also equipped with ASAT weapons, which could be microwave-based systems. The nuclear reactor could give enough energy to that system. To destroy at least other satellites. Officially, Kosmos 954 was a radar satellite. But the nuclear reactor. Caused suspicion that this satellite can also have. Other missions. 

At the beginning of the Almaz program. Soviet-made killer satellites impacted with other satellites. There were satellites. That guided to impact with other satellites. This makes miniature satellites dangerous. Even a small satellite can act as a killer satellite if it collides with other satellites. But evolution formed satellites with special killing devices. Like machine guns or “space bazookas”. There were also manned options.

Like. MiG-105 “Spiral” miniature shuttle systems and Salyut space stations Salyuts 2, 3, and 5 (OPS-1-3). Wirth Almaz numbers 1-3 (Salyut 2 was Almaz 1, etc.), and an unmanned large-size radar satellite, OPS-4. Those were used as platforms to test those ASAT weapons and track missiles. The “Almaz” included. Also modified Soyuz, Soyuz-T, and Progress spacecrafts for intelligence, finding other satellites. And maybe those systems also had a kill option. 

During that program, the Soviets tested quite a massive Polyus system, which could act as a space fighter. It’s possible that there were also planned spaceborne lasers. Those that are installed in the body are similar to “Polyus”. The spaceborne laser can also look like a rejected rocket stage. The chemical laser that gets its energy from the acetylene-oxygen light. 

That is around the laser element. The laser can get its energy from sunlight. And that makes it very effective against other satellites. In the 1980s, the soviets researched laser satellites, where mirrors aim sunlight to laser elements. That laser is claimed to be a civil system, but it's possible that the laser satellite was planned. To be used as a space weapon. 

Then there came special satellites equipped with machine guns and internal nuclear explosives. Those small nuclear bombs that detonated in an air capsule would create a powerful EMP pulse that could destroy a large number of satellites. 

Those EMP weapons can also shut down the US and other nations' air defense. An EMP weapon that detonates in orbital trajectory can create an ion layer between Earth and the satellite, and deny satellite communication with the ground station through that layer. The stalth satellite can sneak up on its target and then detonate the neutron bomb inside it. 

That limits the EMP effect. Another version is a satellite that uses rockets or machine guns. The killer satellite will be launched into orbit in the opposite direction to its prey. And then it launches its “kill-devices” against that opponent. The fact is that when we think about killer satellites, those systems don’t need any nuclear weapons. The killer satellite can be a harmless satellite that has a modified rocket engine. 

The killer satellite can simply deliver oxygen and fuel into one closed chamber. And then detonate that mixture. The fragmentators. Like steel balls can be inside the shell of that satellite. When that mixture detonates, the satellite can deliver those steel balls to space. And if some other satellites are in the line of those metal balls, they can destroy or damage that target. Another version is to inject those metal balls into the rocket engine, which turns the engine into a shotgun. That means those systems don’t need any railguns to turn effective.
