A war in space is not an air war, nor is it a naval war.

The ICBMs of ancient humanity, which constantly accelerated in flight and finally reached Mach 20, this weapon is not suitable for space warfare. Now in space warfare, the competition is the initial velocity, after the missile is launched, it is basically a constant speed, it is useless to accelerate in space by Spitfire, there is no air here, the only way to accelerate is to lose the mass (weight) of the missile, part of the mass slows down or moves in the opposite direction, and the other part can accelerate forward, because the initial kinetic energy of the missile is unchanged.

Where does the speed of the ship come from? It's the same as a missile, it can't accelerate while sailing, unless it's constantly throwing things in the opposite direction. If the ship wants to accelerate, the only way is to get close to the mothership, use the mothership as the focus point, and eject it again, and there are many ways to eject it.

A large fleet needs a mothership of great mass. Whoever has a heavy mothership and leaves the base as fast as this fleet attacks. The mothership is a big iron ball, which does not store anything, it is solid, so that the mass can be large, and all the ships are around this iron ball.

Planets are the best motherships, and the mass of planets can be seen as infinite relative to ships. Therefore, whoever is close to the planet on both sides of the war has an advantage.

Space warfare, there is no terrain, nowhere to hide, there is no way to set up an encirclement, and the enemy can escape 360 degrees. The various tactics of war revolve around how to use the planetary gravitational field to turn the battleship, and how to use a nearby planet or satellite as a mothership to suddenly accelerate your own battleship.

In the vast universe, there is no trace, there is no shadow, and it is even more difficult to find the main force of the enemy for a decisive battle.

There is no air resistance and sea resistance, and with muzzle velocity, you can sail far without worrying about running out of fuel and crashing or flooding the cabin. Nuclear energy is widely used, power is not a problem, and the sailing range is not a problem. Robots have a long lifespan, they can be recharged on ships, and food supplies are no longer the main factor that plagues wars.

Battleships compete in technology. A battle is a contest between the weight of the mothership and the timing of its appearance; A war is a contest of production capacity.

The natural satellite of the planet is the terrain and landform spoken of by ancient humans in space warfare, and it is the natural mothership of the defending side. Saturn has 62 moons and Jupiter has 63 moons, and these two planets are the Taihang Mountains in the history of ancient wars, which can make devils dizzy. Qiu Zuoshu, deputy commander of the Victorian Space Force, did not make good use of Jupiter's natural advantages, and if Jupiter's position was lost, the pressure on Victoria's side with his back to the sun would increase sharply.

Victoria is on the side of the sun and has an old enemy, the Venus Group. Venus and Mercury, close to the Sun, have no natural satellites. Here, as ancient humans said, there is no danger to defend.
