Merv,
Revell/Monogram did have a 1/48th A-6E Intruder; I built it up about six months ago. However, I don't know if its still in production. Its good kit, up to Revell/Monogram's standards, and makes a good companion to their EA-6B Prowler. I used some Microscale aftermarket decals on it - CVW-14 off the USS Independence, Operation Desert Shield, December 1990. VLS did make up some ejection seats which could be used in either the Intruder or Prowler; I used some in the Prowler. Hope this helps.
