I was scrolling through yf-23.net when I saw this page.[URL unfurl="true"]http://www.yf-23.net/ATFprogramme.html[/URL]I was looking at the performance requirements given by the ATF Statement of Operational Need, and I noticed this.the ability to accelerate from Mach 0.6 to Mach 1 in 20 secondsthe ability to accelerate from Mach 0.8 to Mach 1.8 in 50 seconds at 20-30,000 ftThis second acceleration requirement almost seems silly. I haven't been able to find this figure anywhere else, so is this one of the requirements that got relaxed?
