Ah, I see. Udet, you must be trying to adapt airplane combat maneuvers to a space combat situation.
Simple answer for your situation, you DON'T do a 180. In Babylon 5, most of the flight was by combatants within a few thousand FPS of each other.
You have different options when it comes to how to fight. Here are a few I can think of:
1. Slashing attacks. The equivalent of HO's, you charge your enemy and unload everything you can along likely vectors they can maneuver to. The fight is over in seconds, or you both have a few minutes/hours/whatever to turn around and repeat.
2. Stand-off engagement. This would be similar to old infantry or artillery tactics where both sides are far apart and firing projectiles or missiles at each other.
2a. Missiles could be launched enmasse with the intent of overwhelming the other sides defenses.
2b. Stealth missiles could be launched with the design of infiltrating detection networks to engage ships one by one.
2c. Dumb projectiles could be fired by the millions, chemically or electromagnetically with the design of holing their targets.
3. Low-speed close combat. You have close fighting, similar to dogfighting or close hand to hand combat with low relative speeds. The fight might look more like a swarm.
B5 was more like situation 3. You are constrained by the laws of physics. No Wing Commander or Star Wars type airplane fights, you must apply thrust along the proper vectors to maneuver.
PS, I am an engineer.
