As this thread seems to wind about a bit, let me QC Brian's
This scheme went no farther than operational trials, possibly because the workload of trying to fly the aircraft and read the radarscope at the same time was simply too high for a single-seat aircraft.
unless you were a USN F6F-3(N). So combine single-seat fighter plus working the radar plus carrier ops.
I believe the USMC got some of their night fighter Corsairs operational before VJ Day as well.
