The MRFA tender has attracted top global aviation firms. For instance, SAAB’s Gripen E competes against the Eurofighter Typhoon. Boeing also fields its advanced F-15EX and F\/A-18 Super Hornet. Meanwhile, Russia offers its Su-35 and MiG-35 platforms. This intense competition highlights a glaring issue for the French fighter. The current Indian Rafales use technologically dated radar systems. This specific issue is a focal point of the ongoing Rafale debate.<\/p>\n\n\n\n India\u2019s Ministry of Defence is reviewing a critical IAF proposal. The air force seeks to procure 114 advanced fighter jets. This requirement follows an earlier, truncated purchase of just 36 Rafales. Consequently, the new MRFA (Multi-Role Fighter Aircraft) tender was initiated. This program aims to urgently address the IAF’s dwindling squadron strength. However, significant Rafale delays cast a long shadow over its candidacy. Procuring a jet in 2025 without features that competition offers, at 20-25% more cost cannot be justified.<\/p>\n\n\n\n The MRFA tender has attracted top global aviation firms.

This intense competition highlights a glaring issue for the French fighter. The current Indian Rafales use technologically dated radar systems. This specific issue is a focal point of the ongoing Rafale delays.<\/p>\n\n\n\n Concurrently, India develops its own Light Combat Aircraft. The LCA Tejas Mk1A and Mk2 are vital national projects. However, these programs face their own distinct challenges. GE engine delivery delays have impacted the Mk1A program’s timeline. The more advanced Mk2 also depends on foreign engine technology. Importantly, these indigenous aircraft are in a different category. They are not direct competitors within the MRFA tender. This distinction underscores India’s immediate need & LCA family arent related.<\/p>\n\n\n\n Modern air combat superiority hinges on advanced avionics. A fighter\u2019s AESA radar is its primary sensor. Most MRFA contenders now offer Gallium Nitride (GaN) AESA radars. In contrast, the IAF Rafale operates on older Gallium Arsenide (GaAs) technology. This creates a significant performance deficit for the Indian fleet.<\/p>\n\n\n\n Gallium Nitride is a third-generation wide-bandgap semiconductor. Its material properties offer substantial advantages over Gallium Arsenide. GaN boasts higher power density and superior thermal conductivity. This allows GaN-based transmit\/receive (T\/R) modules to operate at higher voltages and temperatures.<\/p>\n\n\n\n Practically, this translates to several key performance enhancements. A GaN radar can generate a more powerful beam. This significantly increases detection and tracking ranges. It also provides higher resolution for better target identification. Furthermore, GaN’s efficiency improves resistance to sophisticated electronic warfare and jamming attempts. The Rafale’s current GaAs-based RBE2-AESA simply cannot match these metrics.<\/p>\n\n\n\n The Rafale’s competitors showcase the latest sensor technology. The SAAB Gripen E integrates the advanced GaN-based Raven ES-05 AESA. Similarly, newer Eurofighter Typhoons feature the Captor-E, which steer the panel and increase the coverage. The American F-15EX is equipped with the powerful Raytheon AN\/APG-82(V)1 AESA radar. These systems provide their pilots with superior situational awareness. They can detect and engage threats from much greater distances.<\/p>\n\n\n\n This technological lag has serious geopolitical implications. China’s J-20 stealth fighter is reportedly equipped with a large GaN AESA radar. Analysts estimate its array contains 2000-2200 T\/R modules. This gives Chinese pilots a decisive long-range advantage. The delay in upgrading India’s Rafales directly impacts the regional balance of power.<\/p>\n\n\n\n![\"\"](\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/09\/image-30-1024x455.png\")
