You'll have to provide some justification to that. In five years, 2320s, we aren't expected to make so many ships that we can afford more than 2 per small sector, 3 per big sector or 3-4 per BZ, and we are expecting a war which will probably have us down to High Alert or State of Emergency levels.
e: And more importantly, ship stats aren't going to change, so what the heck kind of event would need more than 2 ships? Or 3 ships if that's our present limit? Even two Miri-As can handle science events.
Well, let's map it out. In 2321, I'm projecting approximately the following...
~16 Miranda-A
~10 Centaur-A
~5 Oberth
~9 Constellation-A
~8 Renaissance
~1 Constitution-A
~9 Constitution-B
~2 Excelsior (+2 in refit)
~17 Excelsior-A (9 of them in Explorer Corps, leaving 8 for garrison duty)
Assumed sectors
Sol (can be supported by ships from LBZ and SBZ) - Excelsior-A, Renaissance, Constellation-A, Centaur-A
Vulcan (Can be supported by ships from RBZ) - Constitution-B, Constellation-A, Centaur-A
Andor (can be supported by ships from RBZ and KBZ) - Constellation-A, Centaur-A
Tellar (can be supported by ships from SBZ) - Constellation-A, Centaur-A
Amarkia (can be supported by ships from SBZ) - Constellation-A, Centaur-A
Ferasa (can be supported by ships from CBZ and KBZ) - Excelsior-A, Constellation-A, Centaur-A
Rigel (can be supported by ships from LBZ and SBZ) - Excelsior, Constellation-A, Centaur-A
Apinae (can be supported by ships from CBZ and SBZ) - Constitution-B, Constellation-A, Constellation-A, Centaur-A
Romulan Border Zone - Excelsior-A, Renaissance, Centaur-A, Oberth, Miranda-A x 2
Klingon Border Zone - Excelsior-A, Renaissance, Constitution-B, Centaur-A, Oberth, Miranda-A x 2
Cardassian Border Zone - Excelsior-A, Constitution-A, Renaissance, Oberth, Miranda-A x 2
Sydraxian Border Zone - Excelsior-A, Renaissance, Constitution-B, Oberth, Miranda-A x 2
Gabriel Border Zone - Excelsior-A, Excelsior, Renaissance x 2, Constitution-B x 4, Miranda-A x 8
Licori Border Zone - Excelsior-A, Renaissance, Constitution-B, Oberth, Miranda-A x 2
Just as a hypothetical for how we might distribute forces around that time.
e2: And we're going to have cross-border response eventually, which means even less reason to stack up event responders.
I would think more reason to stack up event respondents, because you have a good chance to get usage from otherwise 'wasted' ships in the border zones where there otherwise wouldn't be enough events to use them all.
