HAL Tejas | Updates, News & Discussions

@the bolded part-Not possible as the Engines are Different and the Mark2 Tejas will have it's fuselage stretched by 0.5 Meter(according to officials @ AI'11 and 1 Meter according to BR members).The mark-2 will also incorporate significant design changes that decreases drag.
I am also confused about the numbers of Tejas Mark2 aircrafts that are to be inducted as the Deal signed with GE was for 99 F414 Engines(+possibility of some more).Now if we assume that the Mark2 will follow the Tejas Mark1 evolution(which it will),then there will be a minimum of 6-10 prototypes so I think that the initial IAF order will be for around 80-89 Tejas Mark2 aircrafts

The MK1s can be upgraded to MK2 level, at least to some extend! They might get AESA radar, new avionics and even the upgraded Kaveri engine is planned for the MLU. What might not be integrated is the increased internal fuel, because that's what the airframe changes are meant for mainly.
The ordered numbers of GE 414 is 107, but not all of them will be used for operational fighters, but like you said for prototypes and not to forget for INs orders of N-LCA as well. From some statements of Air Chief Naik, we can assume that besides the 2 x MK1 squads, we will see at least 5, possibly up to 7 x MK2 squads (total of 180 fighters).

Since the K-10 deal yet to be formalised, will it be ready for MLU?

The induction of LCA MK1 is planned for the end of next year, which puts the MLU between 2027 and 2032, so more than enough time even for us.
In the meantime I guess Kaveri K10 will be used for the MK2s as well, at least for follow orders of Indian forces and possibly for exports.

^^^^ by that time (2027) the Kaveri would be ready and powering the production version of the AMCA btw is it true Kaveri MK2 will have 100kn of thrust with afterburner and be fitted with a stealth nozzle to lower IR signature?

"Around" 100kN is speculated, but the normal GE 414 in the F18SH has 98kN, the version in Gripen NG only 96kN and so far there are no official specs. TVC is not part of the package, but it might be added to Kaveri K10, which then could be used on LCA too.

the AMCA will have TVC and be powered by a Kaveri engine so the Kaveri will have TVC i am just wondering if it could be feasible to get a TW ratio of 1 with full load on the LCA

TWRs are mainly calculated with AB thrust and clean, while the fighters normally fly with dry thrust and when you then add external loads, it should be clear that the TWR will be much lower.

Any news on when the latest LSP will fly? weapon trials?
Also any news on Kaveri?

Thanks in advance !

The Light Combat Aircraft (LCA) programme is expected to see a series of maiden flights in the next few months.Three aircraft from the LCA stable, the Limited Series Production (LSP-7 and LSP-8) and the naval variant of the aircraft, Naval Prototype-1 (NP-1) will take to the skies.The three variants, which were to be flight-tested earlier this year, have not been able to meet the deadlines due to technical reasons, incessant rains and a change at helm at the National Flight Test Centre (NFTC), which oversees all flight-tests related activities of LCA programme.

Sources involved in the programme said that the LSP-7 and LSP-8, which will eventually enter squadron service with the Indian Air Force (IAF), would be flown separately followed by the NP-1.

“The aircraft have been subjected to a series of tests which are mandatory before the first flight.” sources said.

The LSP-7 and LSP-8 will be the twelfth and thirteenth aircraft of the LCA programme and would be almost the final version of the aircraft after it enters service.

Under the LCA programme, two Technology Demonstrators (TD’s), five Prototype Vehicles (PV’s), eight LSP’s have been developed and 1,671 flights have been conducted so far since the first flight on January 4, 2001.

The LCA is expected to replace the ageing MiG-21s and to start with, the IAF would raise two squadrons.

Similarly, under the Navy’s programme, apart from the NP-1 another single seat aircraft NP-2 will be developed.

The LCA (Navy) will replace the depleting Sea Harrier squadron and operate along the MiG29 Ks by 2014. The Navy has placed an initial order for six LCAaircraft.


Light Combat Aircraft naval variant may take maiden flight in 2 months | idrw.org

So thats final with in two months LSP-7 & LSP-8 will be fly and most probably will be the first jets to induct to squadron level..

By the way is there any change in radar-weapon combo? its modified version of EL/2032 + Derby/R-73

Over 300 Su-30s, Tejas LCAs to be inducted into IAF

NEW DELHI (PTI): India will procure over 300 Sukhoi-30 MKI fighter jets and Tejas light combat aircraft (LCA) at a total cost of Rs 64,408 crore to strengthen the combat capability of the Indian Air Force, the Government has said.

Replying to a question on procurement of combat aircraft in the Rajya Sabha on Wednesday, Defence Minister A K Antony said, “Su-30 MKI aircraft and Tejas LCA are the major modern combat aircraft that have been contracted for induction into the Indian Air Force.”

“The total cost of procurement of Su-30 MKI is over Rs 55,717 crore while the cost of procurement of Tejas LCA is about Rs 8,691 crore,” he added.

The Minister informed the House that Hindustan Aeronautics Limited (HAL) is already manufacturing the Su-30 MKI aircraft as well as Tejas LCA for the IAF.

“Further, HAL would also eventually be manufacturing the Medium Multi-Role Combat Aircraft (MMRCA) and Fifth Generation Fighter Aircraft (FGFA) planned for further induction into the IAF,” he said.

Replying to a question on submarine fleet of the Indian Navy, Antony said, “A programme for construction of six submarines is currently underway at Mazagaon Docks Limited. Acceptance of Necessity for acquisition of another six submarines has also been accorded by the Defence Acquisition Council.”

To a query on upgradation of harbour protection system, Antony said, “Indian Navy has detailed security plan for its bases which is constantly reviewed in the light of threat perception.”

Procurement and upgradation of naval assets including coastal anti-submarine vessel is an ongoing process depending upon threat perception and naval requirements, the Minister said.

8691 Crore for LCA = 86910 million = (86910/45) = $1931million

1931 ml / 35 ml (average cost of one LCA) = 55 LCAs.

Tejas set to bomb Pokhran & Chandan Ranges

Much ahead of India's Festival of Lights -- Diwali -- India's Light Combat Aircraft (LCA) Tejas is all set to do carpet bombing in Rajasthan! A high-profile team of engineers, test pilots, scientists and ground crew from ADA, HAL, NFTC and IAF have already touched down at Jaisalmer in Rajasthan for the light and sound show.

PV3, LSP-1, LSP-2, Slp-3 and LSP-5 (five platforms from the flight line) have already reached Jaisalmer after a brief stopover at Ozhar Air Force base in Nasik for refueling. "The crucial weapons trials are all set to begin now. We are planning to drop 1000 pounds and 400 pounds bombs at Chandan and Pokhran Ranges," say sources.

One prototype is being readied for Electronic attack and counter attack ala Growler..
