That's a nice summary. You missed the Intraflight Datalinks (IDL) for the
F-22.



He also seems to have left out the ESM system which is quite elaborate
in the F-22. It can take an AMRAAM shot with it without even using
it's main radar. Also he was incorrect on the F-22's speed. The mach
1.7 he lists in in dry thrust and it wasn't even max military power.
Paul Metz stated on a Discovery special that the maximum speed of the
F-22 is classified but that it will go Mach 2.5. To quote him ". .
..it's fast, I mean it's REALLY fast. It's top speed is classifed but
it will do Mach 2.5" This suggests that the top speed in afterburner
is over Mach 2.5. Paul Metz is the chief test pilot of the F-22
program.


That plays a big role in the F-22 CONOPS. Does Typhoon have that
facility? I know Grypen does.

Comparison of tankage would be helpful both internal and with external
tanks.



I have no idea on the Typhoon. The Flanker's is somewhere between 19k
and 20k internal. I don't know what it can carry external. I don't
recall ever seeing one with external tanks. The F-22 at first was
said to have 23,000 internal but then later I saw that it was
something like 18,700lbs. Add the roughly 20,000lbs of four 600
gallon tanks and you get 38,700lb of fuel. Roughly double the
Flanker's fuel load. For comparison an F-15E (or I I guess too) has
something like 13,500 internal, 10k in the conformal tanks and 15k
more in three 600 gallon tanks for a total of about 38,500lbs.


Six different kinds of AAMs on the Flanker? What is that, the AA-10,
AA-11, AA-12 and what AA-8? What are the other 2? R-37 was
cancelled, That air to air Krypton looking thing is a paper design
AFAIK and the AAA-AE or whatever that two stage long range missile was
has never entered service either.
