Индийский истребитель Tejas Mk2 не является устаревшим: анализ технических преимуществ

The claim that India’s Tejas Mk2 is “outdated” before it even enters service has become increasingly common in online defence discussions. However, when examined from an engineering and operational perspective, the argument becomes far less convincing. If the Tejas Mk2 is considered obsolete simply because it is a 4.5-generation fighter entering service in the 2030s, then the same logic would also apply to advanced aircraft such as the Rafale F4+, which continues to receive upgrades and remains one of the world’s premier multirole fighters. The Tejas Mk2 has been designed as a substantially larger and more capable aircraft than the Tejas Mk1A. Its increased size is not merely intended to carry more fuel and weapons but also to accommodate more advanced sensors, computing power and future growth potential. One of the most significant advantages of the Tejas Mk2 lies in its nose volume. A fighter aircraft’s radar performance depends on several factors, including antenna size, transmitter power, cooling capacity, software, operating frequency and the efficiency of the transmit/receive modules (TRMs). A larger nose generally allows engineers to install a physically larger radar antenna, increasing the potential number of TRMs and improving overall radar performance. The Rafale’s compact design imposes certain physical constraints. Powered by two Safran M88 engines producing approximately 75 kN of afterburning thrust each, the aircraft was designed around requirements established in the 1980s. Its relatively small nose diameter limits the maximum antenna size that can be accommodated, although Dassault and Thales have optimised the available space exceptionally well with the RBE2 AESA radar. The current Rafale F4 standard employs the Thales RBE2-AA, an advanced Gallium Arsenide (GaAs)-based Active Electronically Scanned Array (AESA) radar. It is among the most capable operational fighter radars today, offering excellent multi-target tracking, electronic attack capabilities and high reliability. By contrast, the Tejas Mk2 is expected to field a new-generation indigenous AESA radar that is widely expected to transition toward Gallium Nitride (GaN) technology as the programme matures. Compared with GaAs, GaN semiconductor technology offers several advantages, including higher power output, improved thermal efficiency and greater potential detection range for a radar of similar size. If the Tejas Mk2 ultimately receives a larger GaN-based AESA radar with a higher number of transmit/receive modules than current-generation systems, it could potentially achieve superior performance in some radar metrics, such as detection range, target tracking capacity and resistance to electronic attack. However, final performance will depend on the completed radar design, power generation, cooling systems, software and signal processing—not simply antenna size or TRM count. Radar capability alone, however, does not determine whether an aircraft is “outdated.” The Rafale F4+ remains one of the world’s most capable combat aircraft because it combines a mature sensor suite, advanced electronic warfare through the SPECTRA system, extensive combat experience, secure networking, sensor fusion, precision weapons integration and continuous software upgrades. Similarly, the Tejas Mk2 is being designed as a modern network-centric fighter incorporating advanced mission computers, electronic warfare systems, indigenous weapons integration, open-architecture avionics and future upgrade potential. These characteristics ensure that it remains relevant despite being based on a conventional fourth-and-a-half-generation aerodynamic configuration. Another important factor is propulsion. The Tejas Mk2 will be powered by the General Electric F414 engine producing approximately 98 kN of afterburning thrust, giving the aircraft a high thrust-to-weight ratio while supporting increased payload and range compared to the Tejas Mk1A. Although the Rafale benefits from twin-engine redundancy and excellent overall performance, engine thrust alone does not define technological relevance. The future battlefield will increasingly reward aircraft capable of integrating seamlessly with airborne early warning systems, long-range missiles, electronic warfare assets and unmanned collaborative aircraft rather than simply relying on aerodynamic performance. By the time the Tejas Mk2 enters service, it is expected to operate alongside platforms such as the AMCA, Su-30MKI Super-30, Rafale and various loyal wingman UCAVs within a highly networked combat environment. Ultimately, describing the Tejas Mk2 as “outdated” overlooks how modern combat aircraft evolve. Fighter platforms today are judged less by their original design date and more by the sophistication of their sensors, software, electronic warfare capabilities, networking and upgrade potential.
