A -B Tomcat with 50% fuel and full weapons load (not sure what that load is exactly) has just over a 1:1 thrust to weight ratio IRL. So a ton of lift, check, a ton of power, check, big control surfaces to keep it all under control, check, and a good pilot equals one hell of a dogfighter.
Please share your data and/or real world experiences that made you come to the conclusion that the Tomcat "should be" stalling out...
