Overview:

When the Taurian Defense Force was first formed in the year 2360, the 
government of the Concordat knew that their first line of defense would have 
to be naval. Without an active force of warships sufficient to oppose (if not 
outright defeat) any enemy aproach against the Hyades Cluster, the Concordat 
had little chance of standing against a major assault by either of its much 
larger neighbors.

To this end, officers of the TDF put forward a list of requirements for the 
Concordat's first warships. They had to be well armed enough to engage larger 
opponents, fast enough to run when the enemy outgunned them, and they had to 
be able to make long voyages far from a ready source of supply, given the 
lack of available supply bases on most of the Concordat's still young 
colonies. Most important of all, they could not be very large. The Concordat 
had limited capabilities for shipbuilding, and ships much above three hundred 
thousand tons would stretch these capabilities to their limit.

The Defiant class corvette was among the first ships produced as a part of 
that effort, with the first ones comming in service in 2366.

Capabilities:

The Defiant's most important feature has always been the ease with which it 
could be upgraded. Though when most people talk about smart modularity they 
are thinking of the Terran Hegemony's Vincent class corvette, the fact is 
that the concept really wasn't new when the Vincent was launched. The 
Concordat in particular made heavy use of similar concepts with their 
Defiant. They knew that the high costs of warship construction would make a 
hull that could be extensively modified when needed rather than just replaced 
would be an extremely valuable thing, so engineers made sure that the Defiant 
could meet that requirement. Over the course of its career, the Defiant has 
undergone two major refits and numerous minor upgrades, keeping it largely on 
par with its nearest competitors.

The 2566 refit in particular had a remarkable impact on the design. Advances 
in propulsion technology in particular had resulted in a major reduction in 
the ship's engine mass. Taking the opportunity to enhance the vessel's 
firepower, engineers made extensive changes to the hull, making room for 
thirty two light naval lasers and turning the Defiant into a powerful gunboat 
almost on a par with the newer Bulldog (though of course lacking fighters). 
In order to counter the increased power demands of the naval lasers, in 
adition to upgrading the existing power system, workers took the novel 
aproach of installing a trio of large battlemech fusion engines to handle 
much of the ship's minor power needs.

Deployment:

Though many Defiant class vessels were still in opperation when the 
Reunification war had begun, the Concordat had begun to slowly retire the 
class when the better, stronger, and faster Bulldog came into service. Though 
all were refitted with the additional naval lasers in 2566, forty of the 
existing Defiants were placed into mothballs soon after, with most of the 
remainder assigned as defense and supply ships for the Hyades cluster and two 
given the role of deep range exploration vessels.

The precaution of mothballing most of the class rather than scrapping them 
soon proved fortuitous during the Reunification war, when the Concordat was 
able to quickly reactivate the mothballed ships, which were primarily tasked 
with running supplies to the rest of the fleet and defending the Hyades 
Cluster. Most Defiants were lost when the SLDF fought its way into the 
Cluster, though according to legends told after the war, Defiant class 
vessels made up the bulk of the so called lost squadron. 

Another persistent legend of the Defiant claims that several (as many as half 
a dozen) might have ended up in Draconis Combine space. According to the 
story, the Concordat made a deal of sorts with the Combine in which Kurita 
would provide a safe haven for Taurian raiders to strike against House Davion 
and the Terran Hegemony in exchange for a cut of whatever loot the raiders 
recovered. Of course, this legend is nothing more than a rumor, and though a 
rather well equipped pirate band did conduct several opperations along he 
border between Kurita, Davion, and the Hegemony after the war, there is no 
proof that Kurita supported them in any way.
