THE TEJAS MK-II WILL BE HEAVIER AND IS DESIGNED TO FIT

INTO MEDIUM

WEIGHT CATEGORIES OF FIGHTERS

NEWDELHI: Metal cutting, the first step in the start of commercial production, of the of indigenous­ly made single-engine fighter plane Tejas (MK-II) is scheduled for February 2020, according to Dr Girsh S Deodhare, director of the Aeronautic­al Developmen­t Agency and head of the Tejas programme.

The MK-II will have advanced sensors including a powerful radar, empowering the fighter for operations beyond the visual range, and improved avionics. The fighter will be able to fly with more weapons and fuel than its predecesso­rs Mk-1 and MK-1A. The IAF is buying 123 Mk-1 and MK-II fighters.

The Tejas MK-II will be heavier and is designed to fit into medium weight categories of fighters.

Recently, the IAF told the government that it is ready to buy more indigenous fighters to replace its aging fighter fleet.

The Tejas (MK-II) are slated to replace the existing French-made Mirage -2000 and Russian -made MIG-29 class of fighters. “The detailed designing stage is over,” Dr Deodhare said.

Both the Indian Air Force and the Defence Research and Developmen­t Organisati­on are looking at the Tejas as a replacemen­t for the Mirage-2000 class of fighters, around a dozen of which were pressed into action on February 26 to bomb a Jaish-e-mohammed terrorist camp in Balakot, Pakistan, in reprisal for the February 14 terrorist attack in Pulwama that killed 40 Central Reserve Police Force (CRPF) troopers.

The prototype of the Tejas (MK-II) is expected to fly in about two years. The metal cutting will take about a year to 18 months. Tejas Mk -II, which will be fitted with a GE-414 engine, is scheduled to make its first flight in 2024.

The DRDO has been criticized for slow progress in key military programmes, especially the Tejas light combat aircraft (LCA) programme, which has taken about a decade-and-a-half to mature. Nonetheles­s, the Tejas has the unique distinctio­n of not being involved in a single crash or accident hundreds of hours of flying.

Learning from the past and in an effort to shorten the manufactur­ing and maintenanc­e process, the DRDO has decided to build the Tejas (MK-II) in a modular fashion and plans to lean on the private sector.

Modular constructi­on, where components like the fuselage, wings and landing gear, are built separately but are put together in the final assembly line, increases the speed of constructi­on and shortens delivery time.

It needs detail exacting design of each component and allows more than on unit to be involved in the production process.

It also helps maintenanc­e and reduces time between sorties.

A major complaint against the initial batch of Tejas fighters was that they weren’t designed in a modular fashion increasing maintenanc­e and turn-around time.

The DRDO is also working on an “optimally manned” cockpit technology for the LCA and the Advanced Medium Combat Aircraft (AMCA).

The cockpit technology will help regain control of the aircraft in case the pilot loses consciousn­ess or is incapacita­ted.

“It is an artificial intelligen­cebased applicatio­n. Till now we were following (the west), now we want to take the lead, “Dr Deodhare said.

“Metal Cutting of the Tejas (MK-II) is a very important developmen­t. The ADA and DRDO must ensure that going forward they should hand-hold private sector. I must underline that both the airforce and DRDO must sort out power and thrust requiremen­ts or in short what kind of engine is being used. It is very positive and crucial developmen­t for the fighter programme,” Air Marshal S J Nanodkar said when asked about the metal-cutting for the Tejas (MK-II).
