Torpedo speed is relative to stations/asteroids, not the ship it was shot from

[Gorbald]

How to reproduce:

1. shoot a torpedo at a "stationary" target 40km away from a "stationary" ship, measure the time it takes for the torpedo to reach it.

2. In a decently fast ship, start accelerating towards that same target from a further distance, and when you are 40km away from it and your speed is at least about 2000 m/s,  shoot a torpedo. Measure the time it takes for the torpedo to reach it's target.

 

Expected result:

In 2nd experiment, the torpedo reaches it's target much faster

 

Actual result:

In both cases, it takes the same amount of time (about 8 seconds for a 5500m/s torpedo).

 

2nd method of reproducing it: accelerate your ship to 6000m/s, shoot a torpedo and see how it stays behind.

 

So the torpedo does not behave as it should according to Newtonian mechanics. It's starting speed should be the same as the speed of the ship from which it was shot at the moment in which it was shot. Only then it should burn it's fuel to accelerate further.

 

Normal projectiles do not have this issue (their speed is relative to the ship that shot them), only torpedoes.
