LCA AF Mk2 (Medium Weight Fighter) - News and discussions

Sure first flight when ? 2028 ? 2030?
2020 se 2025 suna tha ab 2030 sunn lenge
Tejas Mk2 will have it's FF this year.
As for AMCA, it will have it's FF sometime in 2028-29.

The Tejas Mk2 in its current form did not exist prior to 2019.
AMCA wasn't IAF priority prior to 2020.
GoI spending 3.5 years attracting Pvt sector participation didn't help its case (good thing is LRU work was ongoing in the background so that consortium eventually selected to build AMCA prototypes does not have to start from scratch).
 

Big boost to IAF: GE Aerospace, HAL seal technical pact on jet engines


GE promises twenty F404 engines by year-end; HAL to receive 6th engine by month end

New Delhi: India and the US achieved a key breakthrough on coproduction of fighter jet engines, with GE Aerospace and Hindustan Aeronautics Ltd reaching an agreement on technical matters. This is likely to be followed by the signing of a final contract later this year, in what would be a major boost to the Indian Air Force's attempts to reverse its depleting fighter squadron strength and grow the fleet, critical for a two-front war with China and Pakistan.

The US aerospace company also announced the signing of a contract with IAF for setting up a depot facility for F404 engines that currently powers the Light Combat Aircraft (LCA), seen as a major future backbone of the air force.

Rita Flaherty, vice president, sales and business development for defence and systems at GE Aerospace, told ET that the "hardest part" of technical discussions, which include a complex and deep transfer of technology for the more-advanced F414 engines to India, have recently been concluded.

"GE Aerospace is pleased to announce significant progress regarding F414 coproduction today, having reached agreement on technical matters related to the work," she said. "This agreement marks a significant step forward in strengthening economic growth and advancing national security interests in both India and the US and further expands the 40-year partnership between GE Aerospace and HAL," said Flaherty, who was visiting India for the stakeholder discussions.

Terming it as a "landmark agreement", she said this would result in transfer of manufacturing technology of the powerful engine, supporting India's mission of moving towards self-reliance. Flaherty said GE is transferring manufacturing technology to India and owns about 80% of the engine's intellectual property rights. The balance is held by other US suppliers.

"These are extraordinarily capable machines, but they're also complex," she said. "We can count on one hand all the companies in the world that can do this kind of capability, and now we are bringing this to India, so India can do it for themselves."

GE and HAL will now move to the next phase of holding commercial discussions. These are expected to take some time as global prices for components have risen significantly in the past months. The final signing of the contract is expected this financial year, followed by HAL setting up a manufacturing facility in India with GE's assistance. The plan is to have the facility up and running within two years of contract signing.

As part of the deal, 99 engines will be manufactured in India, powering the Mk2 variant of LCA. IAF has projected a demand for 120-130 Tejas Mk2 fighters, which, if accepted by the government, is likely to swell the order size beyond 99 engines. In addition to LCA, the first two squadrons of the futuristic Advanced Medium Combat Aircraft (AMCA) are also likely to be powered by the same engine.

Flaherty underlined that GE is interested in continuing discussions with India for developing higher thrust engines of the 120kN class for next generation fighter jets

On F404 engines for LCA Mk1a, which have faced significant delays, Flaherty said the sixth engine has arrived in India and that GE is focused on timely deliveries, also considering that there is no compromise on safety and quality standards. On the new depot facility for F404, she said it would be owned, operated, and maintained by IAF, with GE providing technical inputs, training, support staff and ensuring supply of necessary spares and specialised equipment.

Great news👍. Now sign the deal ASAP.
 
First TEDBF then HLFT 42 ...now Mk2..

Someone is rehasing old news .

Hope something real is happening...
 

LCA Mk1 is said to have a third of the M2000's frontal RCS, and Mk2 will have a quarter of Mk1's.

At 0.067m2, that puts it squarely in the Rafale's class, ie, 0.04-0.08m2. Rafale's been designed so a radar that detects a M2000 at 100 km will detect a Rafale from 50.

Mk1 would be 0.27m2, not 0.5m2. At 0.5m2, it would only be a 40% decrease, not 300%. It wouldn't be worth mentioning at that point.

Plus it has Y-duct, not S. It isn't a deliberate stealthy design, just a byproduct of the usual Y-duct design that does well to hide the engine blades. The inlet is supposed to have RAM too. But the cockpit must be the main hotspot for spikes. Switching to printed metamaterials can further reduce RCS, although that applies to all aircraft.
 
What are these claims based on?
I think this was the ADA director himself. I actually remember him saying this although I could be wrong.

bro the rafale does not have a RCS of 0.04-0.08. PLS STOP BEING DELUSIONAL!. like omg . the tejas mk1a isnt going to be 0.1 sq m in a combat situation either. It will be a solid 0.5 sq m(at least) in a a-a config and more in a a-g config. The rafale is not stealth. Just stop ffs.

He is correct though! In X-Band Rafale's clean frontal RCS is between 0.05m2 to 0.1m2. With only 6 MICA BVRs, it's around 0.6m2. With EFTs, RCS shoots over 1m2 and with both EFTs and air-to-ground-load it's around 1.5m2. Clean Rafale is LO from front, lightly loaded(wih only 6 MICA) Rafale is RO and in fully-loaded configuration(with EFTs), it's still quite low on radar. With Active Stealth(which I doubt) it's 0.001m2 from front.

One thing is certain that Rafale is the stealthiest 4.5 jet amongst them all.

Rafale is not LO even in clean configuration. World's first LO aircraft with unretractable refueling prope& IRST , which increases its frontal RCS but still it is a LO aircart how?

VLO is below -30dBsm or 0.001m2 which Rafale claims to be with Active Cancellation Stealth Tech. LO is between -20dBsm or 0.01m2 and -10dBsm or 0.1m2. Rafale's clean RCS falls between this range from front, so it qualifies as quasi LO aircraft. But since Rafale is a 4.5 gen jet and carries its weapons, EFTs etc. externally, it is not LO in combat configuration/real sense. At best it could be termed as Reduced Observable(RO) with light air-to-air load only configuration.
 
From Project Director

"It is not like a Mark 1. Mark 1 has got some X RCS; it is a 1/4 of the X. It is a RCS point of view also, by design, we have taken care"

He didn't mention the figures


In an event at IIT Powai in 1994, I heard a lot of things of when Tejas is going to be ready. Whatever you hear from DRDO or HAL add 2 decades to it, unless it comes under PMO or is a strategic project.

Rafale typically does not fly without drop tanks (even in A2A roles), and with drop tanks its RCS exceeds 5m².
