Exclusive : Indian Navy Tejas Fights Back

Hello Defence Lovers, The Indian navy, however, has rejected the naval version of the Tejas saying it is too heavy to fly from its aircraft carriers and has instead won government approval to buy 57 planes from abroad. Parrikar said the navy wanted a twin-engine fighter to operate from its carrier and a stronger landing gear. “They are supportive of the LCA programme, they have made a financial contribution to it.”

  • On Tuesday here at the Aero India show, Defence Minister Manohar Parrikar added the latest in the series of nails in the coffin of the troubled LCA Navy, the carrier version of India’s in-service LCA Tejas.
  • By now, the LCA Navy team in Bengaluru had gotten round to the reality that a paper plane that began in 2003 wouldn’t ever be an operational jet with a customer.
  • Parrikar cajoled the team separately, assuring them that the government had no plans to pull the plug, and that the good work the team at the Aeronautical Development Agency (ADA) had done for over a decade would not go to waste.
  • But the reality stuck. All that work on LCA Navy Mk1 wouldn’t result in sales of the aircraft. It would be forever be a technology demonstrator.
  • The last six months have brought headwind way beyond what this little jet was built for. But beyond the claimed stoicism of continuing endlessly with a project nobody wants, there’s a reality that has gone unreported so far.
  • Livefist met with ADA chief Commodore C.D. Balaji for what he described after as the frankest chat he’s had on the subject. And at the centre of the LCA Navy’s struggle for relevance is a solid kernel of hope.
  • The ADA has opened dialogue with the Indian Navy with the hope that its customer will come round to the view that the LCA Navy Mk.2 will be a sensible graduated step to the big twin engine jets it finally wants to operate.
  • The LCA Navy Mk.2 would be a great stepping stone,” Balaji tells Livefist. And he’s backing his pitch with a solid timeframe.
  • They are aiming for a first flight of the LCA Navy Mk.2 in late 2020 or early 2021.
  • The detailed design will be complete by 2019. To save time, we’ve already ordered raw materials required,’ Balaji says.
  • Two GE F414 engines — one for the AF prototype and one for the LCA Navy — arrived earlier this month, the first batch of eight engines contracted from GE for the Mk.2 programme.
  • That the LCA Navy will be a more powerful combat jet is well known. What Livefist has now discovered from the team is that there are design and engineering improvements being effected on the LCA Navy Mk.2 that could prove dealmaker if they work out.
  • In the immediate future this summer, the LCA Navy Mk.1 prototypes will begin ‘taxi in engagement’ drills, where the jets are throttled on ground into the arrester wire at Goa’s Shore Based Test Facility (SBTF) to exercise structural compatibility for a hook.
  • The tests have been delayed three months thanks to a damper failure during field carrier landing practice (FCLP) dummy approaches last year.
  • ‘Our focus with the Mk.1 is carrier suitability. We’ve got a good handle on carrier ops. Control laws have matured well, and sit right on top of our simulations. Deck recoveries are a different challenge and there are several lead-up activities planned,’ he says.
  • The ADA has built a new test rig to test horizontal and vertical loads during a deck recovery, including 7.1 m/s sink rate and the 45 ton load on an arrestor wire.
  • ‘Structurally, everything checks out,’ Balaji says, adding, ‘We are doing more dummy approaches to fine tune our control laws. Want to narrow everything down so we have very predictable landings.’
  • There’s activity on the radar front too. Balaji’s team will freeing up LCA Tejas LSP-2 shortly for ground integration of India’s indigenous Uttam AESA radar.
  • The ADA has asked the DRDO’s LRDE lab to keep the Uttam’s interfaces as similar as possible to the current system.
  • It will be a challenge, moving from a mechanically scanned radar to the AESA without interface changes but that is the attempt, to save time and forestall any structural changes to the aircraft or radar,’ says Balaji.
  • A full scale model of the LCA Navy Mk.2 will be ready by early next year. Commodore Balaji and his team now hope their case will have a firm taker by then.
