Depends on how the writers or the Confederation would define one.
For some reason, they were termed
fighter carriers, the
Midway class weighed in at two hundred kilotonnes with fifteen hundred thirty tonne fighters; modern ones are only mentioned as having between two to four hundred fighters.
The American super carriers may actually be able to outrun any warship capable of damaging it, it's classified and the one time an ex Navy nuclear engineer brought it up in conversation, said that when they practiced it, it left the rest of the escorts eating their dust.
Traditionally, Traveller carriers tend to have an acceleration of two, which means they can't make a run for it, they'd have to jump.
Let's say the average cruiser squadron has about four fifty kilotonne cruisers, and no fighter screen. Their objective would be to close with the enemy carrier as soon as possible, and unleash their spinal mounts; if they get the range, and keep closing, and the carrier can't jump, it's over.
Let's assume the carrier matches tonnage at two hundred kilotonnes; likely it has enough tertiary armament and point defence that missiles or ordnance aren't likely to damage it; secondary armament such as bays would keep destroyers at a respectful distance.
So it's a question whether the heavy fighters are enough to mission kill the four cruisers, if not destroy them.
At the optimum end, using current rules, fifteen hundred thirty five tonne fighters should wipe out four cruisers, because you can make called shots and damage the manoeuvre drives; and you could have a thousand concentrate on one cruiser at a time.
Once the manoeuvre drives are knocked out, the other cruisers have to decide whether to continue or stay concentrated; in one case, they can't close the distance to the carrier, in the other, they won't enjoy the combined defensive fire power covering each other, so they could be taken out separately.
At the other end, you have two hundred heavy fighters from a one hundred kilotonne fighter carrier, which would have the same number of firmpoints as the thirty fiver.
In theory, the fighters have the advantage if they manage to get into dogfight range, because they can just empty their missile magazines within six minutes, using the current rule set, contrasted as to actually where the energy weapon systems of the cruisers could draw the extra power needed for each shot in each dogfight round.
