I think you might be right. I made that ship so long ago that I couldn’t seem to find all the sites that I used for reference (I try to use multiple sources to confirm statistics). I believe its top speed is higher than 30 knots, but not as high as 38 knots. Do you have any other corrections? (I'm sure you do...) :P

Special Qualities: hard to aquire by radar (DC 45 Computer Use); Longbow targeting system: (Doubles equipment bonus to attack)
Oh, and Deucalion, LASER is an acronym too: "Light Amplification by Stimulated Emission of Radiation," but i'm sure you knew that. LASER and RADAR have both become common enough to enter the general vocabulary, and as such can be referred to as words.
I think that Deucalion may be right on the GAU-8, the only article I could find mentioned that the bursts where limited to 1 or 2 seconds "in practice" to reduce wear and chance of jamming on the aircraft and weapon. I cant find anything showing a physical limit on the duration of fire.
To limit ammunition consumption and reduce wear on the vehicle the gun can fire half or full speed, depending on if one or two of the guns engines are engaged. This is achieved with a half or full pull of the trigger.
Cargo: 16,000 lbs (external)
Top Speed: 770 (77 chase) (8 air)
Hit Points: 52
Fuel: 5 hours
Max Cieling: 45000ft
Stall Speed: 165 (17 chase) (2 air)
This airplane recieves a +2 to maneuverability due to superior performance. (already factored into mod)
Height: 15 ft (3 squares)
Width: 58 ft (12 squares)
Length: 54 ft (11 squares)
At chase scale a warthog takes up 4 squares.
Maverick ATM and Sidewinder AAM have already been statted elsewhere.
Makes sense, I know of no vehicle-mounted weapon with a burst limiter.
Please explain this ROF mechanism?
Maybe a payload statistic is needed, separate from cargo space?
Why these ratings?
Stall speed? (It's "ceiling," but good job on these stats. Maybe a range stat would be appropriate, since ranges are more known?)
They have such??
Looking good ...Why's that??
Any link(s) to the Maverick and the Sidewinder, or do you mean the Menace Manual Sidewinder? And pray-tell, are you using the scale seen in MM? (7.62mm Minigun = 4d10, Sidewinder = 20d6, and so on.)
I'll review the munitions themselves later.
The GAU-8 produces ~half the thrust of both engines at full power. The aircraft needs both engines at full power to mantain speed while performing combat maneuvers. So fireing the gun during a rapid turn could, theoretically reduce speed enough to cause a stall danger. But you really need to be flying pretty close to strait at your target to hit anything, so this risk is rather limited.
The GAU-8 has two independant electric motors that spin the barrel assembly. When one is engaged, the gun spins ant ~2000 rpm. When both are engaged, the gun spins at twice that speed (3900 rpm) and fires twice as fast. The trigger has 3 positions: off, speed1, speed2.
I am considering the GAU-8 to be a "weapon system" combining several 30mm cannons using the rules for fire battery and fire linked weapons from d20 future. Fire battary allows you to fire some or all guns in the battery, every time you double the number of guns, you get +50% damage dice. This accurately reflects the variable speed of this weapon.
perhaps, it should be noted that the payload can only be mounted on the 11 pylons.
As for the maneuver, the A-10 is noted for its fantastic acrobatics, it can outturn an F-16 at low altitudes even when fully loaded with bombs. So I gave it a +2 to maneuver.
I chose the hardness and HP to reflect the crafts toughness due to armor and redundant internal support structure. The lear jet has 44hp, the A-10 is much tougher than a lear jet. The 12 hardness is to reflect its armor plating of steel and titanium.
Stall speed is a statistic that is not important under standard d20 modern vehicle rules. Its there for those that use more detailed rules. Flight time is Flight Time is a simple mechanic that requires less book keeping overall than tracking round to round movement rates. Most range estimates for the A-10 also include a variable amount of loiter time due to its roll as a CAS aircraft.
it is more than 50ft wide and 50ft long. it wont fit in 1 square (1x1), it will fit in 4 squares (2x2)
The Maverick and Sidewinder were statted in a bullet points article IIRC, I dont have a link but IIRC 20d6 for the Sidewinder is correct.
In d20 modern core, a 30mm cannon does 4d12 damage (as my stats for the GAU-8 indicate).
In Weapons Locker a 20mm AMR does 4d8 damage. My stats for the M61 Vulcan 20mm cannon are modified to 4d12 for 2 reasons. 1: to account for the weapons superior ROF (6000 RPM) and 2: to make it easier to work them into a battery arangement with the main gun.
If you want it to work as the Menace manual mini-guns, Then they should probably be hitting for 8d12 and 8d8 without regard to thier actual Rates of fire.
Now that we're talking about this kind of thing, here's a question: what do you think a Phoenix (or whatever's the name) Point-Defense System (it's those miniguns that are on the carriers, you know, for missile defense) can do in D20 terms?
Re: maneuverability. Its just something that you need to imagine, some vehicles are more maneuverable for thier size. There is no particular formula for it.
I do think that some starship rules do make sense for modern vehicles.
Re: f15, not quite... The GAU-8 as I have statted is armor piercing. ignoring 10 points of hardness. The GAU-8 can also "battery" itself to up its damage to 6d12. So in effect the A-10 does ~21 more points of damage per hit than the F-15. Even when doing this, the A-10 is using 2/3 the ammo of the f-15.
RE: armor. I made it up. I figured it was a bit tougher than the average steel plate, but not as tough as the armor on a bradley or tank.
