The reason they had all the protection around a huge convoy during WWI and WWII was because they really couldn't detect U-Boats without sonar, and sonar wasn't developed until what, like mid-WWII, and after not all ships had sonar.
Now, it would be stupid to use a massive convoy because all ships use sonar and can detect submarines.

In Wing Commander, space after the Kilrathi War was kind of devoid of action, save pesky pirates and Kilrathi raiders. But surely even a weak escort of Exacaliburs could defend against those...
Eh...
I wouldn't expect to see a convoy during 'peacetime'. Privateers, pirates, and such are typically interested in the bottom line, and attacking even a lightly defended group of transports is going to entail some risk. War-time commerce raiders will plow through any lightly defended transports, while pirates will figure out how much they're likely to get out of it versus how much they lose.
So I don't think you need to worry about convoys.
The reason they had convoys during World War 2 wasn't so much about the U-Boat as it was about attrition. Run twenty seperate ships (with an escort or two) through the Atlantic, and you may only lose a few of them, but you'll keep losing a few of them every time you run ships through since you're probably not killing the raiders. Run a convoy through, and a wolfpack may gather, but they're going to have to slip through a sizable escort, sink the transports, and then get out.
And they're probably going to lose a few subs.
So they may do well the first time or two. They might even do better than they would against the twenty seperate ships. But before long, the losses will start to tell, and you'll start getting more ships through.
And incidentally, sonar is a lot more prevalent these days, but it isn't perfect. A skilled sub commander can still find ways to lose a sonar lock by moving through thermal layers and the like. What sonar DOES do is two things:
1.) Lets the surface ship know that there's something down there (along with a rough 'last known position').
2.) Tells the sub EXACTLY where the surface ship is. If the surface ship isn't too careful, there might be a torpedo coming right back along with that sensor ping.
