MK1 will never come upto IAF's standards for a frontline fighter - so no need to push too much in this arena. Instead, go ALL OUT and concentrate efforts into a bigger better MK2 And complete the whole FOC testing by 2022 so that serial line production can start by 2023! MK1-P is definitely a good effort with Elta AESA radar IRST integrated and EW-CCM/CCCM avionics suite. But, weight problems causes shift of CG of a/c and this involves quite a bit of redesign of a/c's internals.. This is taking away precious time and engineering resources from MK2 re-design and that MUST NOT happen at all!Roger Hagarhttps://www.blogger.com/profile/02856083913111168858noreply@blogger.comtag:blogger.com,1999:blog-3545138702780178046.post-76997138716093454632015-02-25T17:22:23.707+05:302015-02-25T17:22:23.707+05:30For AMCA & Tejas MK2, MK3 fighters a commonali...For AMCA & Tejas MK2, MK3 fighters a commonality of engines is a dire-tatamount requirement, in order to cut overall projects costs well into the future- 2030's!! Two different engines from two different manufacturers is just wasting of funds for production and TCO's of these engines. Also, TVC nozzle is a MUST-requirement, at least for the future AMCA & MK3 Tejas versions! Sincerely hope that HAL ADA teams takes these factors into serious consideration, when they finally decide on what engines to go in for MK2 in the next year or so. Same manufacturer of engine for MK2 MUST provide TVC nozzles for future engine tranches.Roger Hagarhttps://www.blogger.com/profile/02856083913111168858noreply@blogger.comtag:blogger.com,1999:blog-3545138702780178046.post-72759584993989800102014-04-24T16:11:53.002+05:302014-04-24T16:11:53.002+05:30LCA-MK2 is a potential game changer that could thr...LCA-MK2 is a potential game changer that could threaten fighter aircraft export industries of Sweden, France, and Israel. But, in order to achieve this dream there are many pit-falls:<br />#1.India absolutely needs an Indian fighter aircraft engine of the quality and specs of EJ200 Tranche-3 & F414-GE-INS6 with 360 degrees full TVC nozzles.<br />#2. Dependencies on foreign vendors engines for the LCA & AMCA projects is a disaster waiting to happen!<br />#3. In order to achieve indigenous reliable fighter aircraft engine technologies, a strong steering committee needs to be formed at center under Defense Ministry to strictly monitor GTRE's R&D efforts in this area. If GTRE appears to be failing in their endeavours then, fresh efforts with consultancies from Russia RD-33MK and EuroJet EJ200 engine manufacturers may have to be called-in.<br />#5. Bottom-line if not for the LCA series the AT LEAST for the AMCE we MUST have Indian built TVC engines!Roger Hagarhttps://www.blogger.com/profile/02856083913111168858noreply@blogger.comtag:blogger.com,1999:blog-3545138702780178046.post-86834001211084972842012-04-16T13:17:06.735+05:302012-04-16T13:17:06.735+05:30Thanks for the share.

For the Navy's reqmt for a 120kN higher thrust variant of the F414-IN56, it is still too early to take a call on this since the LCA (Navy) Mk1 will be used for carrier deck-landing trials between early 2013 and 2015, and only depending on how it all goes, design/re-engineering work on the LCA (Navy) Mk2 will begin by 2016. Therefore, it would be premature to discuss anything about the LCA (Navy) Mk2's assumed extra weight at this stage.Prasun K.

It was only last June that the final design modifications were agreed upon and it was then decided to stretch the fuselage by 1 metre to accommodate the extra avionics LRUs that the IAF wanted on-board. Regarding the term ‘increased fuel capacity’ it is interesting that the ADA booklet fails to qualify it with either ‘internal’ or ‘external’ wordings. In fact, the modifications reqd for enlarged air-intake ductings to cater for increased airflow for the higher thrust F414-IN56 turbofan have left very little room for additional internal fuel tanks. What is now being explored is whether or not it would be possible to ensure increased fuel storage on the wings, which would feature enlarged wing areas. To me, however, this appears unlikely and therefore in all probability any increases in fuel load will most likely come from larger external fuel tanks than the existing 1,200-litre fuel tank.Prasun K.

I was referring to the upgrade options for these Mirage 2000s. But as I had explained earlier in my earlier posting, it makes no financial sense to upgrade the IAF Mirage 2000s as offered by the French. If at all the upgrades are reqd to be undertaken by the IAF, then other alternative options/offers need to be considered seriously, since the Mirage 2000s can be maintained in service until the early part of the following decade.

That's precisely the reason why the Indian Navy has never had a spares shortage for Russia-origin equipment of the kind the IAF is now facing. Secondly, the IAF's Maintenance Command now needs to retrain its existing human resource manpower to begin servicing the C-130J-30s and in future the C-17A Globemaster IIIs. Therefore, something has to give way, and the best option is to outsource the maintenance reqmts of the IL-76MD and IL-78MKI-90 fleets to an India-based private party. That's what is happening now.<br />Regarding the Mirage 2000s from Greece or UAE or Qatar or Egypt, it all depends on the price offer, since id India were to acquire them, they would not be able to get upgraded--unlike the MiG-29UPG---with new engines.

We all know the Greeks have the latest Mirage 2000s that were the last to come out of the production line. <br /><br />Also there are reports that UAE plans to replace its entire fleet of Mirage 2000s with Rafale, with Dassualt buying the jets.

The competition is still ongoing. Both the RACR and SABR AESA-MMRs are available without any preconditions. If the F414 turbofans are available without any preconditions, there's no reason why the AESA-MMRs from the US shouldn't be. The Vixen-1000es has already been selected by Saab for the Gripen-NG and it is derived from the Captor-E and therefore, there's no reason to doubt the Vixen-1000es' capabilities, just as the RBE-2 is maturing day by day. By in terms of proven performance parameters, no one can presently compete with the RACR (derived from the APG-79) and SABR (derived from the APG-81). Armaments packages can be acquired from anyone (US, France or Israel), depending on the operational reqmts. <br /><br />To Anon@10.31PM: No LEVCONs for the Tejas Mk2, but the LCA (Navy) Mk2 will have LEVCONs.
