I have always been on the lookout for the Prowler. So far none to my knowledge. I was involved in some of the technical aspects of the A-6's for flight of the intruder. These were 10' models with 2 DF no landing gear. They would be Ideal with Turbines. The twisted tail pipe was the down fall of the DF version. It could be better done with a Turbine. The prowler would have to be a modified Intruder at this point. There is a smallish A-6 by Meys that is DF.
