Ah. Even then, though, I think there were at least a few more destroyers than that. They definitely weren't up to FS2 levels, though.
While your guess is as good as mine, since we don't have any canon information from

in regards of the fleet organizations during FS1, there's a lot of reasons that lead me to believe that there is only one Orion per fleet.
First of all, we never get to see more than one Orion during mission (granted, that was to keep the framerates acceptable back in '98, but that's an out-of-universe explanation, and therefore not valid

). Second, we are never told of any other Orions that for example, would accompany the Galatea (for example in the asteroid escort mission). Third, I've always thought that Orions are one of the most expensive things to build ever, and therefore their cost would prevent widespread deployment.
