A spaceship is a popular subject to model,so I decided to create a battleship. It won’t be a truly realistic design, as those build nowadays are boring, but a sci-fi one, but without any ultimate gadgets. I consider it “quarter-realistic”.
First of all, a basic environment and strategy description. I don’t think that the future space battles (if any will be) will resemble something seen by now. The space is insanely huge and the speeds at which anything flies in space are also very high. This makes the spacecrafts very expensive, because of high-end technology needed to produce them. Also, the ship itself is a weapon capable of destroying entire countries on planets. The terrible destruction power will make them similar to nuclear weapons, but many times stronger. So instead of dramatic battles like in movies, I think there won’t be almost any, or only against much weaker opponents.
Now to the ship itself. A huge, with mass of 70 000 tons monster is a good way to demonstrate the power of a country. Being 360m long and high (with radiators extended), mainly to store large amounts of propellant to enable her to get anywhere on solar system, she is one of the largest combat ships. The shape has evolved from Mothership from Homeworld 2, but now it far from original. With small cross section from front, which is also the only armoured part it is supposed to always face the enemy. Although it might not be possible to accelerate during this maneuver it is the best to position to defend because the of the small angle between the enemy and armour plates.
Powered by a fusion reactor with total output of about 400 GW (and efficiency about 80%, which is a bit too high) she is a threat, even unarmed. With armament of 20 missiles with multiple nuclear warheads, a big laser and few kinetic cannons in a main turret, she can easily defeat any opponent. For defence, there is a number of small lasers and effective space machineguns.
Carrying 32 000 tons of liquid hydrogen, she has maximum delta v of about 400 km/s, but to accelerate to this speed, about 10 months are needed. The exhaust velocity of 700 km/s means a good fuel economy.
The majority of crew are officers, because of high level of automation. The battleship doubles as command and flag ship.
Any comments or suggestions for improvement are welcome, as well as critics. Also discussion about possible space colonization, war and everything similar. I hope, I will start the actual model soon.
