E3 FC's that will be thread creep
I think that you'll find that a number of E3 FC's have been doing tours of both sandpit/Stan with 1ACC and other locations.
Various plans for B707 platforms to give common airframe to ease spare probs both at home and deployed if co-located with RJ135/E3's have been muted.
BUT and it is a big BUT the kit down the back of the R1 is not the same as a RJ135.
My solution, buy 5 CFM56 cargo door B707. pay to zero life the frames and then palletise the kit withe all 5 a/c having the antennas and use the serviceable one to fly the missions. Any other serviceable kites can be split for PCT for all 4 squadrons.
