Why Indian Airforce buying tejas even they are more costly has less range,less hardpoints?

IAF’s philosophy is to maintain a spectrum of fighters:

1) Heavyweight (  air superiority with secondary multi-role capability)
2) Medium weight (Multi-role, ground attack, strike, deep penetration)

3) Light weight (Interception with limited multi-role capability)


Su-30MKI (air-superiority+multi-role)

Medium weight:

MiG-29 (air superiority+multi-role)
MiG-27 (Ground attack)
Mirage-2000 (Multi-role)
Jaguar (Ground attack, deep penetration)

Light weight:

MiG-21 (Interceptor)

Tejas is a modern jet developed to replace MiG-21. It doesn’t have to be similar to Su-30MKI because it’s category and role are supposed to be different.

Tejas it's a good aircraft:

1) 4+ gen (Mk1A will be 4.5 gen including AESA radar, better EW suite, self-protection jammer etc.),
2) all weather/all terrain/all altitude compatible (being tested in every condition for 17 years),
3) swing-role (computerized configurable multi-role capability),
4) Advanced flight control system(Quadruplex 3-axis digital fly-by-wire) 5) advanced avionics and systems (Glass cockpit, HUD, HMD/S, HOTAS, Night vision goggle, Multi-mode radar, EW suite with radar warning receiver, LASER warning receiver, Missile approach warning receiver etc., targeting pod, LASER rangefinder etc.)
6) agile and highly maneuverable (cropped compound delta-wing design, unstable design with relaxed static stability),
7) semi-stealthy (90% surface area composite material, small airframe, blended wing, Y-inlet, RAM coated body, Indium Tin oxide coated canopy, EW suite),
8) production friendly (single piece monolithic honeycomb structure tailfin, composite structure reducing 40% parts, 50% fasteners, 2000 holes, cost and time compared to metallic design)
9) maintenance friendly (can do 6 sorties per day without problem)
10) versatile (Indian, Russian, Israeli, western weapons compatible, 8 hard points- standard for a small light fighter, tandem pylon),
11) safe (zero accident in 4000+ test flights along with 3 years of operational flights, Digital fly-by-wire, advanced control law, auto-pilot, auto-level, Integrated avionics, computerized health monitoring system, FADEC engine etc.),
12) long endurance (3000 km range with one aerial refueling- hence good range, On-board oxygen generator system, pilot-friendly systems etc.),
13) cheap (just 1 billion USD overall developmental cost- lowest in all light fighter programs in the world)
14) Diverse (Air Force version fighter, Air Force trainer, Lead-in fighter-trainer, Naval fighter, Naval trainer, Unmanned version)and high scope of upgrade (mk1, mk1A, mk2)
15) indigenous (designed, developed and manufactured in India, 75.5% indigenous LRUs in 2016 which was increasing).

It’s  definitely a good aircraft.

We need it because it’s good and it’s highly important to be self-dependent in aviation sector in defense. Tejas program has given India a fighter (operational), a naval fighter (reached maturity for carrier testing), a jet engine program (reached maturity for aircraft testing), a fighter-graded AESA radar program (prototype ready) as well as a whole aerospace ecosystem as a network of 50+ labs, 20+ educational institutes and 500+ firms. All these are not for throwing out to dustbin.
