It was stated in a post Destiny book that Starfleet had to rebuild and could focus on exploration cruisers again, though I don't remember the book or exact quote. I figured this to mean they had been pumping out warships, ie Defiants.
The
Defiants weren't the only class designed with combat in mind after the Borg contact. At least in some behind-the-scenes or fan sources, that's believed to be the design philosophy behind the
Sovereign and the other classes that showed up in
First Contact like the
Sabre, Steamrunner, and
Akira.
And I don't follow the assumption in
Relayer1's post that
Defiants are quick and cheap to make. They're overpowered, heavily armored, excessively beweaponed. That probably makes them harder and costlier (in resources, time, and energy) to make than a standard ship. A tank is probably harder to make than an ATV or a Humvee.
Sure they had a high rate of attrition mf but no doubt production was equally vast.
"No doubt?" How do you justify these absolute statements? They're just assumptions. I see plenty of basis for doubt.
Sure they have limited capabilities and overpowered engines. But outfit them with slipstream and you got a serious deterrent against the typhon pact.
"Deterrent?" Come on, if the Federation took such an aggressive action, it would
provoke the Typhon Pact into responding in kind. The Pact formed because they were afraid of the Federation's dominance and wanted to be strong enough to achieve self-determination. That means they don't want to start a fight, they just want to be left alone. The best thing the Federation can do to "deter" the Pact is to avoid looking like a threat to them. In other words, to do what the Federation
usually does, which is to engage other civilizations with friendship and diplomacy.
