Fighter Planes with lowest Production Rate

[Graham Boak]

The lowest rate is obviously zero, but as there was more than one Hawker Tornado it surely is possible to find a fighter with only a single prototype - there is a French fighter that springs to mind - one built, one kill, so beat that! The SNCAO 200.

However, I think the question was really aimed at aircraft that did go into production. The problem is made more murky by the German habit of a specifically pre-production batch: these should really be included. I suggest, without looking the numbers up, that the He 112 had a low total production run, and the He 100 even lower. You could look at the Welkin, which were fewer than the Whirlwind.
