Detail of Combat Aircrafts in news

1. Rafale & MMRCA

Rafale is 4.5 generation Medium Multi-Role Combat Aircraft (MMRCA) aircraft made by Dassault Aviation of France.

Rafale and India

Main features of Rafale

  • 4.5 generation Multirole combat aircraft, i.e. can be used for ground support, in-depth strike, and anti-ship strike.
  • Rafale is capable of carrying nuclear weapons.
  • Equipped with precision air to air and air to surface missiles.
  • Range: 3,700 Km
  • Max Speed: 1,389 Km/hr
  • Load Carrying Capacity: 9,500 Kg

Rafale Acquisition: Chronology of Events

2007 Tender for MMRCA was invited, and various bidders such as  Eurofighter (of British Aerospace), F-16 (of Lockheed Martin), MiG-35 (of Russia) and Rafale (of Dassault (France)) applied for the bids.  
2011 Rafale was shortlisted. It was decided that India would buy 126 Rafale. In this, 18  were to be purchased in fly-away condition, and the rest 108 were to be made by HAL under Transfer of Technology.  
2015 But the issue was Dassault was not prepared to guarantee the performance of aircraft manufactured in IndiaThe plan was changed, and the government decided to buy 36 Rafale in the ready-to-fly condition given to India in two years.
2018-19 The case went to Supreme Court to increase the cost per aircraft and give offset contract to Reliance instead of HAL.  
2020 Delivery of Rafales started. The first batch of 5 aircraft was delivered to India.

Issues

  • The stealth system of Rafale is outdated compared to other competitors in the same class.
  • Rafale doesn’t have STOVL (Short take-off and vertical landing) capability, present in other competitors.
  • Brazilian Airforce was earlier interested in buying Rafale but later changed to Swedish Gripen jet.

  • Tejas is going to replace India’s ageing MiG 21 aircraft.
  • Features of HAL Tejas
    1. It has ~60% indigenous content.
    2. Maximum Speed: 1,350 Kmph.
    3. Its radius of action is 400 Km without refuelling.
    4. It can carry a weight of up to 12 tonnes.

Side Topic: (LCA) Kaveri

  • Kaveri is the name of Tejas’s engine that was to be used, but India couldn’t make it on time to be used in the plane.
  • It would have been India’s first indigenous gas turbine engine.

3. Sukhoi T-50 (Fifth Generation)

Sukhoi T-50 is an Indo-Russian collaborative project to make 5th generation fighter aircraft. It is a joint venture of Russia’s Sukhoi and India’sIndia’s HAL.
