The problem would be that 90% of the time you probably will be flying alone and therefore not live very long.It's a ship that relies on a pilot's skill... and surprise when operating alone.
In numbers it will be deadly.
True, I hadn't considered this re-imagining of it and was thinking more of the version from FE2/FFE. As you say, this could well be a more combat orientated craft and therefore be much more dangerous than the venerable Cobra Mk.III, which after all is a trading craft.
Ability to fit weapons greatly reduced due to the vessel size, and hull would be comparable to a modern fighter jet, which is easily destroyed by direct impact from any missile I have ever heard of... In other words, harder to hit but easily destroyed once a hit strikes.
