It was started to develop as an answer for F-14 first in 1969, only after F-15 showed up they decided to claim it was also an answer for F-15.
Typical Soviets, cant even make first flight in 10 years while his enemies already started to use F-15.
No Su-27 was developed as a ПФИ promising front-line fighter, AS A RESPONSE TO the FX PROGRAM even before the appearance of the F-15
Why make an answer to the F-14 when the USSR does not have aircraft carriers?And all the main events unfolded in Western Europe

FX program didnt even come to life until 1972 so what you’re claiming is basically nonsense.
The USA felt the need to develop the F-15 because it overestimated the capabilities of the Mig-25.
The first flight of the F-14 in 1970, the development of the Su-27 in 68, I do not see a connection here
Stop writing nonsense
Same can be Said about you.
You also claimed Su-27 developed for to counter F-15 while first fly of F-15 was 1972.
Stop writing nonsense.
FX Studies
April 1965 - FX studies begin. Air Force Systems Command studies end up recommending a 60,000lb VG design with air-air and air-ground capability.
December 1965 - RFP issued to 13 companies for concept formulation for a TSA (Tactical Support Aircraft)
March 1966 - 8 bids recieved. All were VG designs except Northrop. Boeing, North American Rockwell, Lockheed awarded contracts. Vought (V-483), McDonnell-Douglas (Model 199), Grumman (G-300?), Northrop make unsuccessful bids. McDonnell-Douglas carries on in-house studies on Model 199 from April to December 1966 without funding, as does Grumman. Rockwell work on a primary VG design and a second, higher risk blended fixed wing design, which seems to promise to make VG unnecessary. A closely related fixed wing design (NR-323) was submitted to the VFX competition, despite having little chance of succeeding, perhaps to gain experience for the FX program.

The Su-27 was originally developed as a response to the FX program, and while development was underway, the F-15 appeared
27 July 1972
The first F-15A flight was made on 27 July 1972 , with the first flight of the two-seat F-15B following in July 1973.
As you can see what you’re claiming is nonsense.
You’re writing bullshit right now.If you don’t know anything about the development of the Su-27 (and you really don’t know) Then I suggest you shut up

Ah Yes Soviets somehow learned every detail about FX program and they decided to develop something to counter in 1968, Meanwhile F-15 didnt made its first flight until 1972.
Intelligence, espionage, have you not heard?
Oh look our Soviet Fanboy got mad.

Manners, educate and civilization, have you ever heard about them? No? Not surprised.
The MiG-29 is also the answer to the FX, because the competition was originally for one aircraft
What does this have to do with intelligence and espionage?
You need more hints Einstein?
🤨🤦🤦🤦🤦
I understand its too hard for you to understand what does bein civil and educated mean.
Dont worry i dont judge you since you believe Soviets/Russians were ahead of USA when it comes to developing Military Vehicles.
Mig-29 was an answer for F-16 in the first place.
Both vehicles are designed to be light frontline fighter while F-15 and Su-27 designed to be long range Air Superiorty fighters.
