Air-hed- The first unit to be detrimentally involved with a Fokker Triplane was 6 Sqdn, RFC, who lost an R.E.8 to MvR in F.I 102/17 on 1 Sept 1917. MvR also shot down Lt Bird of 46 Sqdn in a Sopwith Pup on 4 September.
Werner Voss shot down ~ 10 aircraft using F.I 103/17. These victories were from several units, British and French, and began on 3 September and ended on the morning of 23 September. He was shot down the same day in an afternoon fight with 56 Sq. Wolff was shot down in F.I 102/17 on 15 September by MacGregor of 10 Sq RNAS. After 23 September virtually no Fokker Triplanes, Dr.Is this time, were seen at the front (a few possibly in the last week of Oct) until after new wings were fitted and the grounding was lifted in winter 1917/18. MvR did not score another Triplane victory until 18 March 1918.
See the Forum Aces section for more info.
For later meetings, here is a web site I have found valuable that shows the locations of all the Jastas on any given date. Line this up with Entente information and you have a pretty good idea who was fighting whom. You probably already know this, but primarily Dr.I equipped units included Jastas 2(B), 4 (late), 5 (late), 6, 11, 12, 13, 14, 15, 19, 26, 27, and 36. Done from memory so may have missed a few. Dr.Is also were passed on to other units in ones or two as D.VIIs became available in the Dr.I equipped units. Jasta 4 and Jasta 5 both got hand-me-down Dr.Is.
