If memory serves me correctly, I've seen discussions of a studied navalized Mirage III in a Fench book, As I remember, it had a samll horizontal tail added about 2/3's up the vertical to help with the control needed when coming aboard ship. I know it was in the two-volume Docavia set on French military and experimental aircraft from 1945 to 1960 and I believe I've seen it at least mentioned in Jack Gee's Mirage, along with mention of the Boeing-built Mirage IIIW proposal.
