I'll say proper focus on Super Sukhoi will be much better than acquiring the Su35.
Tejas MK2 being in development nullifies the need for Gripen as you said, I just hope we can develop the jet fast enough and america won't delay supplying the GE F414 like they did with the F404, I don't like that America can completely hinder our Tejas MK1, Mk1A, MK2, TEDBF and AMCA programs like what happened with the Marut, We need to speed up with the Kaveri, Indo-French Engine and maybe even redesign the Tejas MK2 with different russian core if necessary to derisk the entire program.
From my perspective, the very existence of the "medium fighter" classification is quite bizarre.
For major global powers, a "heavy-and-light" high-low mix is the most rational approach. Heavy fighters are characterized by twin engines, while single-engine light fighters serve as auxiliary assets to expand fleet size and reduce operational costs. Crucially, both types must share a common engine core—the only difference being the number of engines installed. The most textbook example of this doctrine is the F-15 and F-16 pairing.
For smaller nations, however, only a heavy fighter possesses the multi-role capability required to handle all mission types, making a pure heavy fighter fleet the most rational choice. Currently, the optimal solution lies in platforms like the Su-30SM or modernized variants of the F-15E (such as the F-15K), which are capable of undertaking everything from training, patrolling, and air-to-ground strikes to air defense, interception, and anti-ship operations. In short, the emphasis here is purely on multi-role versatility.
So, coming back to the main topic, where exactly did the so-called "medium fighter" come from?
The answer is simple: the earliest examples were the Rafale and the Eurofighter Typhoon. Medium-sized European nations like the UK and France initially sought a daily multi-role fighter that could execute every single mission required by a mid-sized power. Why did it turn out to be a medium fighter instead of a heavy one? The reality is that Europe at the time lacked both the capability and the engineering experience to develop large, Low-bypass-ratio, high-thrust turbofan engines. Therefore, these aircraft were designed strictly to satisfy their basic homeland defense requirements.
However, two exceptions—the F/A-18 and the MiG-29—need to be analyzed separately. These two are entirely different animals compared to Europe's Rafale and Typhoon; in fact, from the very beginning, they were never part of a standard "light vs. heavy" classification.
First, consider the MiG-29. It was designed as a frontline tactical fighter for the Soviet Air Force (VVS). Meanwhile, the Su-27 was developed as a long-range interceptor and escort fighter for the Soviet Air Defense Forces (PVO). The Soviet aerospace branches operated under highly distinct divisions of labor. The MiG-29, much like the F-15A or Europe's Rafale and Typhoon, was designed to contest air superiority in localized theaters on the Cold War frontlines—essentially tailored to the geographical dimensions of European nations.
Conversely, the Su-27 was engineered around the mission parameters of the PVO. Its original purpose was to defend the vast, sparsely populated expanses of the Soviet homeland and provide long-range escort for strategic bombers. Although people today frequently compare the Su-27 directly to the F-15, the truth is that the Su-27 is nearly 25% larger in overall dimensions, and its engine thrust belongs to an entirely different class. Similarly, the physical footprint of a MiG-29 is significantly larger than that of an F-16. Thus, the MiG-29 just happened to be sized perfectly for localized European warfare, which naturally made it a full size smaller than the PVO's massive Su-27. The two were never intended to form a "light-heavy mix" to reduce logistical pressure via engine commonality; their divergence was purely a reflection of the doctrinal division between Soviet frontline tactical aviation and homeland strategic air defense.
Next, look at the F/A-18. Although it started as a competitor to the F-16 in the Lightweight Fighter (LWF) program, it lost. However, it caught the eye of the US Navy, which resurrected it as a carrier-borne strike fighter. When the program restarted, the F/A-18's airframe was significantly enlarged. Yet, this scaling up was not done to meet some arbitrary "medium fighter" threshold; the Navy simply demanded greater range and ordnance payload, which required a larger fuselage. To achieve this, they severely sacrificed the exceptional maneuverability and supersonic performance that the original prototype prided itself on. Its relationship with the F-14 Tomcat was that of a strike bomber to a fleet defender—completely different operational responsibilities, rather than a medium-to-heavy mix.
Therefore, for a major power like India, I see absolutely no practical value in specifically choosing the Typhoon or the Rafale. Such a move saves no money and only introduces massive logistical nightmares. It would be far more rational to position the Su-30MKI as the core of the air force, and then utilize its AL-31 series engine core to power an Indian-built light fighter.
This mirrors the logical pairings we see today: the Su-57 and Su-75, the J-20 and J-10, or the F-15 and F-16.
