F-14 is disposable so why lose a brand new aircraft by testing new engine along new radar as an example.
You must have reading comprehension issues. You said F-14 is not useless it can be used as testbed, I then clarified by “useless” i ment for the future it is useless as design for next gen fighter jet.
Then you continue talking about using it as an engine test bed. Which im not even debating. Get back on topic.
China conducts tests of new radar and engines on older aircraft until they are used on newer production aircraft.
You are having an argument with yourself. No one is talking about testing engines on F-14, I’m not sure why you decided to come into this discussion to divert it to a separate discussion on F-14 as a test bed.
F-14 is ideal testbed for both because it is basically in terms of size for engines and radar comparable to Su-27 series and its variants like Su-30 and Su-35.
No one is talking about engine test beds. We are talking about design of the next gen Iranian fighter.
Also RCS of an aircraft can be reduced through use of for example composite materials replacing parts made out of aluminum.
Sure, there are variety of RCS reducing measures. However, to get an F-14 design under RCS of 1m2 would require a complete overhaul of the design of the plane including getting rid of swept wing design. Which at that point why would you not start off with fresh design?
Using F-14 to test engines is fine (Iran is already doing that with heavily overhauled F-14 engines using Iranian components per Air Force commander). Using it to test next gen radar is also fine.
However, Redesigning the entire airplane and adding composite and titanium to test integrity is a waste of money and time. That is what prototypes are for.
