Mains Paper 3: Internal Security | Security challenges and their management in border areas

From UPSC perspective, the following things are important:

Prelims level: AMCA

Mains level: Increasing IAFs stealth capacity and fleet


Advanced Medium Combat Aircraft

  1. The Advanced Medium Combat Aircraft (AMCA) India’s next indigenous fighter is expected to make its first flight by 2032.
  2. The aircraft will be powered by the same GE-414 engine on the LCA Mk-2 variant which is in the design phase.
  3. A GE-414 produces 98kN thrust compared to 84kN thrust of the GE-404 engine which is on the LCA Mk1.
  4. The Indian Air Force has given land to the Defence Research and Development Organisation to set up facilities for the project.
  5. The plan is to build on the capabilities and expertise developed during the development of the light combat aircraft (LCA) and produce a medium fifth generation fighter aircraft.
  6. At Aero India 2016, DRDO officials had stated that the basic design configuration has been frozen after wind tunnel testing and there are three critical technologies that need to be developed — stealth, thrust vectoring and super cruise.

Improvising Stealth Capacity

  1. There are two major ways of making a military platform stealthier. One is geometric stealth and other is material stealth.
  2. In geometric stealth, the shape of the aircraft is designed at such angles so as to deflect away maximum radar waves thereby minimising its radar cross section.
  3. In material stealth, radar-absorbing materials are used in making the aircraft which will absorb the radio waves thus reducing the radar footprint.
  4. The AMCA will initially be based on geometric stealth.
