High-Tech has the stats.

Are you referring to the GE Vulcan 20mm?. I'm looking for somethign that's comparable to what might be mounted on a F-22 Raptor

(oh and what is the "follow up 2d" mean"?

Yes, the stats are for the GE M61A1, the Raptor carries a newer variant, the GE M61A2.

It means it uses the Follow-Up Damage on p. B381.

The F-22 Raptor mounts the M61A2, which I believe would use the same stats as the M61A1 described in High-Tech, except that it weighs less. The rules for follow-up effects are explained on p. 105 of Characters and p. 381 of Campaigns.

Thank you for reply. One last question is the M61A2 any different stat wise?

It’s lighter, but I assume that’s largely material improvements that don’t otherwise effect stats. Probably more expensive in GURPS (constant) $ terms, too.

The A2 can supposedly be operated at an ROF of 6600 rounds per minute instead of 6000. (The lighter barrels can apparently be spun faster, along with saving weight.) Not that that's enough to make a difference in the RoF table on B373 :) Some of the aircraft either version has been used in have an option to fire at 4000 rpm, so +6 instead of +7 with the benefit of having more turns worth of ammo.

The ammo storage is different for every installation, custom-designed for that aircraft. So it's not really a stat of the weapon, but of the aircraft. The ammo itself and the barrel length is the same, so most stats will be identical.

You might argue for a slightly improved Malf, since the A2 is supposed to require less maintenance, but that's probably below the level of resolution of the system.
