Twin Engine Deck Based Fighter (TEDBF)

About Twin Engine Deck Based Fighter (TEDBF)

• It is a canard delta-wing, twin-engine, carrier-based, multirole combat aircraft currently under development for the Indian Navy.
• The TEDBF is being indigenously designed and developed by the Aeronautical Development Agency (ADA) and will be manufactured by Hindustan Aeronautics Limited (HAL).
• It is intended for carrier-based operations and is expected to replace the ageing MiG-29K fighters on the INS Vikramaditya and the upcoming INS Vikrant aircraft carriers.
• Key Features:
  • The TEDBF’s twin engines will enable shorter take-offs from the Indian Navy’s Short Take-Off Barrier Arrested Recovery (STOBAR) aircraft carriers.
  • It will have a maximum take-off weight of between 24 and 26 tons.
  • The TEDBF fighters will be able to reach Mach 1.6 speeds.
  • Designed specifically for carrier-based operations, the TEDBF will feature foldable wings for more compact storage, enhancing the flexibility of carrier operations.
  • It will be equipped with various homegrown Indian weapon systems and avionics.
  • It is intended to perform various missions, including air supremacy, air interdiction, anti-access/area denial (A2/AD), anti-ship warfare (ASW), and electronic warfare (EW) missions.

What is a canard on an airplane?

• A canard is a fuselage-mounted, horizontal surface that is located forward of the main wing to provide longitudinal stability and control.
• Depending upon the installation, it may be a fixed, moveable, or variable geometry surface and may or may not incorporate control surfaces.

What is a Delta Wing?

• A delta wing is a type of wing design characterized by a triangular or delta-shaped planform.
• In this design, the wing has a straight leading edge and a swept-back trailing edge, forming a shape reminiscent of the Greek letter “delta” (Δ).
• Advantages:
  • The delta wing offers advantages in structural integrity and both high-speed and low-speed flight.
  • Because of the wing’s large surface area compared to its span, it can be built stronger and stiffer and also has a greater internal volume for fuel storage.
  • Delta wing aircraft do not require a horizontal tail. 
• Disadvantage: Higher viscous drag due to the large wing area.
