The Ukraine War has already proven that Starlink as it exists today in civilian form is already a game changer. If sensor satellites could make a constellation that was over target 100% of the time and could track a ship to support a missile lock (not sure if this is possible with the constellations being built today but it sure isn’t possible with a old style system like the yaogan) then that would be transformative for a Pacific War scenario.

That's essentially the goal: weapon targeting quality tracks, across 100% of the planet, 100% of the time. (Albeit probably with limited simultaneous tracks)
