I'm sure most of us have by now reached the end-game, wherein we graduate from our frigate fleets to mightier vessels. But one common problem when moving up a pay grade like this is that it becomes harder to catch fleeing vessels in combat. Your big, shiny new ship is sure tough, but also quite slow. Initially I kept my old frigate fleet around in reserve and used them to hunt-down fleeing transports and the like. But once I'd saved up enough cash, I decided to upgrade to a carrier and fighter support. However, I soon realized that fighters weren't all what I thought they would be... it almost feels like they are effectively just another class of frigate. A much crappier one at that.
Fighters seem to have roughly the same initial cost, same burn speed, same combat speed... but generally inferior offence and defence. You might suspect that they have a "hidden" defence bonus because they move faster than frigates, and therefore can dodge fire -- but that point is moot if you use high-end frigates like the Wolf, whose combined combat speed, teleport, and longer-ranged guns lets it dodge fire better than any fighter (but with much heavier shielding and armament than fighters). Initially I thought their inferior combat ability would be compensated for by using them with a carrier, you know, so that instead of a good ship with a single life (frigates) you'd get bad ships that could die over and over (fighters).
Then I looked at the heavy fuel and supply demand of fighters+landing bays (the carrier's upkeep costs divided by the number of landing bays), and found the results surprising. While the per-unit cost of a fighter with landing bay had roughly the same per-unit fuel costs as frigates, they consumed far more logistics (works out to ~4-7 supplies/daily per fighter with landing bay, compared to 1-2 supplies/daily with frigates). So the frigates are more combat-worthy, AND cheaper to maintain? Even if fighters can be re-spawned for "free", their increased daily supply cost means that for the same price tag, you could afford replacing the occasional frigate without losing money.
Anyways, that's my review of the fighter, and why I'll probably never use them again until they're rebalanced. It's worth noting that I'm still a fairly new player to the game, so please feel free to point out any oversights I may have made. I genuinely love the concept of fighters and carriers in space sims (I mean, who doesn't? They're as iconic to space sims as the battleship) but I feel like they're simply worthless for anyone who wants to squeeze the most combat ability out of their fleet.
