The Indian Air Force (IAF), tasked with securing one of the world’s most contested airspaces, operates a dizzying array of fighter jets—MiG-21s, MiG-29s, Su-30MKIs, Jaguars, Mirage 2000s, Rafales, and soon Tejas Mk1A and MkII—spanning seven distinct types from Russian, French, British, and Indian origins. This multi-vendor patchwork, while historically driven by geopolitical and technological needs, has become a logistical and operational albatross.
With a sanctioned strength of 42 squadrons but only 31 operational as of April 2025, and a spate of crashes exposing maintenance woes, the IAF must pivot toward commonality: a streamlined fleet of three to four jet types, sharing engine linkage and covering low, mid, and high-end roles. This shift would enhance efficiency, reduce costs, and bolster combat readiness without the burden of managing 7-8 aircraft types for overlapping missions.
The IAF’s fleet diversity reflects decades of ad-hoc procurement. The MiG-21 (50+ years old) and Jaguar (45 years) handle light and strike roles, respectively, while the MiG-29 (35-40 years) and Mirage 2000 (35-40 years) serve as multirole fighters. The Su-30MKI (25+ years), with over 260 units, dominates the heavy multirole category, supplemented by 36 Rafales since 2020. The Tejas Mk1A (light) and MkII (medium) are emerging as indigenous replacements, but their integration adds yet more complexity. Each type uses distinct engines—AL-31FP (Su-30), Adour (Jaguar), RD-33 (MiG-29), M53-P2 (Mirage), F404/F414 (Tejas), and M88 (Rafale)—creating a maintenance nightmare.
This multiplicity strains resources. Spare parts, training, and repair facilities differ across platforms, inflating costs and downtime. The 2025 Jaguar crashes near Jamnagar and Haryana, alongside MiG-21 incidents, underscore the toll of ageing, vendor-dependent fleets. Posts on X lament delays in Russian spares for MiGs and Su-30s, while French support for Mirage and Rafale comes at a premium. The IAF’s 0.20-0.27 crash rate per 10,000 flying hours (2020-2024) exceeds peers like Israel (0.2) or Australia (0.5-1 annually), partly due to this logistical sprawl. With China’s PLAAF fielding a more uniform J-10/J-16/J-20 lineup, India’s fragmented approach risks falling behind.
The Case for Commonality: Three to Four Jet Types
A leaner fleet of three to four jet types, built around common engines and roles, offers a solution. The IAF needs a low-end light fighter (10-12 tons MTOW), a mid-tier multirole jet (15-20 tons), and a high-end air superiority/strike platform (25-30 tons), with a potential fourth for specialized missions. Here’s how this could work:
- Low-End: Tejas Mk1A (GE F404 Engine)
- Role: Light fighter, ground attack, and interceptor.
- Status: 83 ordered, 97 more in pipeline; replaces MiG-21s and Jaguar Darin-I by 2028-29.
- MTOW: ~13.5 tons; 84kN thrust.
- Why: Indigenous, cost-effective ($40-50 million/unit), and scalable with HAL’s production ramp-up.
- Mid-Tier: Tejas MkII (GE F414 Engine)
- Role: Multirole fighter, replacing MiG-29s, Mirage 2000s, and later Jaguars.
- Status: Production begins 2029; 120+ planned.
- MTOW: ~17.5 tons; 98kN thrust.
- Why: Bridges light and heavy categories, shares F404/F414 engine family with Mk1A, reducing spares diversity.
- High-End: AMCA Mk1/Mk2 (GE F414 or Indigenous 110kN Engine)
- Role: Stealth air superiority, deep strike; replaces Su-30MKIs long-term.
- Status: Mk1 (2029-30), Mk2 (2035+); 100-150 planned.
- MTOW: 25-30 tons; 98kN (F414) or 220kN (twin 110kN).
- Why: Fifth/sixth-gen tech, aligns with MkII’s engine initially, transitioning to indigenous powerplants.
- Optional Fourth: Rafale (M88 Engine)
- Role: Strategic strike, nuclear delivery; complements AMCA.
- Status: 36 in service; potential 26 more for Navy.
- MTOW: 24.5 tons; 150kN (twin M88).
- Why: Proven, bridges gap until AMCA matures; limited numbers minimize vendor sprawl.
Common engines are the linchpin. The GE F404 (Mk1A) and F414 (MkII, AMCA Mk1) family offers a proven, scalable solution, with HAL already licensed to produce F404s and negotiating F414 co-production. This reduces training and spares overhead, as seen in the U.S. Navy’s F/A-18E/F and EA-18G (both F414-powered). Transitioning AMCA to a 110kN indigenous engine—under development with DRDO—by the 2030s ensures long-term self-reliance, potentially powering a twin-engine MkII variant too. Retaining Rafale’s M88 as a stopgap limits foreign engines to one type, manageable with France’s reliable supply chain.
Scenarios and Benefits
- Low-End (Tejas Mk1A): Intercepts conducts close air support in Ladakh and Western Region of the Border. At 18-20 squadrons, it replaces MiG-21s and Jaguars, freeing maintenance for higher tiers.
- Mid-Tier (Tejas MkII): Engages with mid-tier jets like J-10CE and F-16 in the area. 10-12 squadrons phase out MiG-29s and Mirage 2000s by 2035.
- High-End (AMCA): Can Penetrates Air defenses for deep strikes of Pakistan and China, Used to establish Air Superiority
- Rafale (Optional): Kept to Deliver nuclear payloads or maritime strikes in the Indo-Pacific, supplementing AMCA until indigenous stealth matures.
This structure achieves 42 squadrons by 2040: 18 Mk1A, 12 MkII, 10 AMCA, and 2 Rafale. Commonality slashes logistics costs—estimated at 20-30% of the IAF’s $5 billion annual budget—while boosting serviceability (currently 50-60% for Su-30s vs. 80% for Rafale). A unified engine pool also simplifies training, addressing CAG-noted pilot shortages.
