The above Mach 2+ capability apparently went out the door when the glove vanes were removed, dont know how much the engine change had to do with top speed reduction either. <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>
The glove vanes were locked shut on all F-14A's in the mid 1980's, and they still retained their Mach 2.38 dash capability. The retractable glove vains were later deleted on the F-14D all together, this had no real effect on the high mach number performance of the aircraft, that is exactly why they were deleted, as were other initial design feautres that were deemed "dead weight". The mach 1.88 is striclty an operational restriction, not a capability limit, as is the 6.5 G limit. Stress can probably explain all of this much better, and if I re-read his deductions, he probably already has.
I am not sure if the DFC upgrades in the 1990's had anything to do with the high speed performance of the F-14, but have read that it made a tremendous difference in the low speed realm. Either way its all for not, the F-14 provided the fleet with maritime air supremacy for 3 decades...After the Teddy Roosevelt returns from its current deployment the Tomcat will call it a career.
