Re: US military fleet retirement dates

The B-21 will replace the B-1B and the B-2 if I'm not wrong. The F-35A will probably displace most if not all the F-16s. The F-22 replacement is on the horizon. I'm not sure what's the plan for the KC-135: is the KC-46 intended to replace all of them or is the USAF going to launch another tanker pr...

Re: Should a fighter aircraft's aerodynamic shape be influenced by optimization of performance in the transonic zo

I think Vintage should post this on F-16.net and multiple F-16 pilots will say acceleration through the transonic is extremely important for a fighter. Linking transonic performance to dogfighting shows a lack of understanding in fighter engagements. When would very high speeds be desirable in a dog...
