Let's try this again.
A submarine has to be ware of surface ships since it can be destroyed easily if detected and caught. A phase ship has to be ware of shielded ships since it can be destroyed easily if it runs out of flux in a bad position.
Any battleship has to be aware of the tactical situation unless it wants to be destroyed quickly. Its basics from the begginings of the line of battle era which developed exactly from the idea of keeping warships in the best position.
Or it can be hounded by fast fighters until it has to unphase.
Normal ship can be outright
destroyed by fighters. Sub too.
Locate->destroy.
Phase:
Locate->wait till unphase->destroy.
A submarine carries strike weapons that can quickly destroy a capital ship. A phase ship carries strike weapons that can quickly destroy a capital ship.
And since the times of the first ram had been implemented, capital ship also carries strike weapon that can quickly destroy a capital ship. Before that there were super-heavy (comparatively) guns for this very purpose.
A submarine will try to find a good angle of attack so it can hit and run. A phase ship will try to find a good angle of attack to flank a ship so it can hit and run
The zone of immunity concept was all about getting a warship into good distance and angle. And before that the whole ram era was about the same. Ah... Wait... And the sail age. The last thing - submarine isnt supposed to actually run after attack. If target was only single ship and is destroyed there is no need to run. If there are other combatants in area it will only helps them to located the submarine and after this submarine unable to outrun most of the surface ships anyway.
Phase ship can.
You are talking about tactical basics for
any type of the warship. This applies to Starsector too. Good luck charging through death ball in your
shielded Onslaught with dozen enemy frigates right behind you. Didnt work? Has to be ware of your surrounding? Does it make the Onslaught a submarine?
(and to clarify, I'm talking about how a typical phase ship would typically be used in the game by the player or in AI fleets, not about specific systems of specific models of phase ship nor about atypical tactics and fleet compositions involving phase ships)
These
specifics are in the game and they used in typical battles. Looks like you didnt get to meet the mass phase ship fleets and thats all.
For some reason what I was saying translated in your mind to "I will hereby rigorously prove that WWII submarines are isomorphic to Starsector phase ships" and set out to list counterexamples to disprove the theorem. While what I was actually saying was there are some similarities between submarines and phase ships, which there are.
There is no theorem. It was stated "since submarines in starsector are phase ships" and "there are strong parallels". Claim of the fact. This was disproved by me by providing conceptual differences between submarines and phase ships. Since then you are only trying to sell some good old ad hominem mixed with cherry picking.
