As you have already been told above, the initial design for all Su-30s is the Su-27UB of the Irkutsk plant!.
1.Su-30/Su-30K-air defense fighters…
2.Su-30MK (1993)_The first demonstrator aircraft with that name…
India signed a contract on November 30, 1996 for the supply of 40 Su-30K/Su-30MK units, the contract provided for 4 stages of deliveries with a gradual increase in combat capabilities…The Su-30Ks of the first batches were serial Su-30s with minor changes in equipment and navigation system…On June 11, 1997, the official presentation of the first eight Su-30Ks took place at the Lohegaon Airbase…The second batch of ten aircraft (1999) is officially called the Su-30MK (these aircraft were originally for Indonesia, which it was unable to purchase for financial reasons), although in India the first batch of Su-The 30K is often referred to as the Su-30MK…
The Su-30MKI(T-10PMK-1) first flew on July 1, 1997…The first batch of 32 serial Su-30MKI from the Irkutsk plant was delivered to India in 2002-2004.
5.Su-30MKK_The first flight was on May 19, 1999…
They differ from the Su-30MKI in the vertical tail of a larger plane, height and thickness from the Su-35 aircraft, the first with the same name, or rather the Su-35 (Su-27M).,engines and does not have a front horizontal tail…
even then the russian huds are alot better than the rafale one imo
you get less clutter on your hud and still all the relevant information
also the rafale hud isnt even especaily good for simulator battles,
the only hud that is special/ better for simulator is the Eurofughter HUD because it is able to show you all your radar contacts at once which gives you great situational awarness
