I backtracked through 8 pages and didn't see the previouse post requesting this aircraft and I can't remember who wanted it, so this is just to let them know that theres been an A-3B, a EA-3 and a KA-3 released over at nonodes (Flightsim.com) 8)
They were designed with CFS2 in mind but should work in 2k2 and 2k4.

P.S.The KA-3 even has an extendin drougue  8)
