Yes, it has always been a middle point between the Y-Wing and the B-Wing, but with a few differences. These are the complete stats of the relevant ships as extracted from the original game in the series. I include also the X-Wing, A-Wing and the TIE Fighter in the same game for context:
- Y-Wing: Hull = 42, Shield = 75, Speed = 80, Accel = 8, Roll = 28, Pitch = 13, Two Lasers, Two Ion cannons, Two torpedo launchers.
- B-Wing: Hull = 63, Shield = 100, Speed = 91, Accel = 12, Roll = 36, Pitch = 14, Three Lasers, Three Ion cannons, Two torpedo launchers.
- Gunboat: Hull = 30, Shield = 100, Speed = 88, Accel = 12, Roll = 64, Pitch = 15, Two Lasers, Two Ion cannons, Two missile launchers.
- X-Wing: Hull = 21, Shield = 50, Speed = 100, Accel = 12, Roll = 44, Pitch = 15, Four Lasers, Two torpedo launchers.
- TIE Fighter: Hull = 10, Shield = 0, Speed = 100, Accel = 15, Roll = 48, Pitch = 20, Two Lasers
- A-Wing: Hull = 15, Shield = 50, Speed = 120, Accel = 16, Roll = 60, Pitch = 18, Two Lasers, Two missile launchers
So all in all it has:
- Missiles instead of torpedoes, that makes it better at intercepting and worse at attacking capital ships.
- Similar shields to those of the B-wing.
- Double the hull of an A-wing, but half of that of a B-Wing. Just between the X-Wing and the Y-Wing.
- Speed between the Y-Wing and the B-Wing.
- Maneuverability is measured in two different axes: The Pitch rating is how fast it can turn upwards or downwards, while the Roll rating is a combined movement that mixes classical yaw and roll into one. In the flight sims, when you move left or right, your ship both yaws and rolls in that direction. So Gunboat has identical pitch rating as the X-Wing, but one of the highest roll ratings in the game.
- Acceleration is on par with the X-Wing and B-Wing.
