    I might be wrong but it appears that navy are more interested in a naval variant of LCA than AF being interested in a land-based one. BTW someone might be able to carify if IN has already allocated some funds for naval LCA?

    that is just the way the IN has always been. being the smallest of the 3 service arms, they’ve learnt to make do with less money and in many cases the only way to get what they want is to fund indigenous programs and actively participate in their development. the IN has been very supportive of the N-LCA and they did allot funds for its development, but I dont recall what the figure was.

    besides, they’re not that badly affected by the delay in the N-LCA program right now, they have other things to worry about- they have the SHar upgrade going on, are facing a spares shortage on that front and now will recieve MiG-29Ks almost on schedule, which wont have a carrier to fly on till 2012.

    that entire report is made up BS. the fact is that accomodate the F-414 in place of the F-404, the intakes or insides would not need to be redesigned because the airflow requirements of the two engines are almost the same.

    this was clearly mentioned in an article on the Future Gripen.

    besides, there is a difference between thrust and handling, EDITED FOR AD HOMINEM

    Did you see the Flankers at Car Nicobar?

    that was Car Nicobar ? I did’nt know whether it was somewhere in the South or Andamans. so, the Jag IM is also at Car Nicobar then.

    Well, last I heard the LCA was not exceeding Mach 1.4 and had handling and aerodynamic issues. So, I don’t think that would be a problem for the F-5M. 😀

    Note: Iran modified the F-5 considerably along with its intakes? I wonder what gains were had……:rolleyes:

    handling issues ? utter BS.

    the Tejas when it’ll enter service will be have RAM coated composite skin (not a biggie, even MiG-27s in IAF service have RAM coating applied), treated canopy (technology for that has been developed already).

    approx 690 mm antenna MMR with some Elta 2032 technology, BVR R-77/Derby, WVR R-73/ Python equipped and a RCS that’ll be smaller than most contemporary fighters thanks to higher composites and very small size. add to that avionics that will be as good if not better than the Su-30MKI which is easily the best fighter in Asia right now.

    its a no match.

    You might as well compare the all metallic, JF-17 with its smoky RD-93 engine that’ll give it away from a good distance if the BVR shot misses. anyhow, even that’ll be only when it finally enters service. :rolleyes: you ought to compare the MiG-21 Bison to the F-5BR, then you’re talking sense, Edited for trolling. Consider yourself warned.

    Personally, its hard to see the value of a fighter that maybe equal to a 20-30 year old design? (i.e. Mirage 2000) Especially, considering it would be many more years before th Tejas is likely to enter full squadron service…………Really, at the rate the LCA Program is progressing. Many countries will be fielding 5th Generation Types! 😮

    that applies to the J-10 which is said to just about match the F-18. nothing to suggest that its any better than a vanilla Hornet. After all, there are no official figures, and all we have is internet fanboys’ figures.

    and the JF-17 which is below even a F-16A in generational terms except for its avionics after the first 50-60 enter service.

    for the types that the Tejas is supposed to face in battle (if that ever happens), the Tejas is good enough. PAF is’nt getting a 5th generation fighter anytime soon and even if China is working on one, it wont be entering service anytime soon either. so stop trolling. :rolleyes:

    oh and Vikas, regarding your question about whether the IAF will accept the Tejas in a pure air-to-air role in the first blocks and then gradually make it multi-role- if that was the case, ADA would’nt have integrated the Litening on the Tejas. if nothing else, its a clear indication that the IAF will not accept anything less than a fully multi-role fighter. the MMR’s biggest issues were in the A2G modes, not the A2A modes (one of which was not working well, but I can’t recall which one).

    Abhimanyu, I personally have no doubt that ASR of Tejas would be superior to Mig-21s. Its simple logic for this to be the case, otherwise IAF would have simply replaced the old Mig-21s with new ones. However, your post raises an interesting point. If the ASRs of Tejas nearly match or exceed the Mirage-2000 in technology, are you referring to original M2K or later updates of M2K? OTOH, if MRCA is to be as late as you are saying-in this could actually happen in every likelihood-what would happen to IAF’s overall strength in between? Am i right in assuming that they would be forced to look for further stop-gap solutions, i.e. possibly buy more MKIs etc and/or upgrade more Mig-21s?

    With regard to ASR, soes IAF want LCA to be a fully fledged true multirole machine from its induction or are they planning to take a machine which is able to do a few things like air defence (to start with) and gradually evolve into a true multirole platform?

    Vikas, the ASRs would have stated what the IAF wanted in terms of payload (which is much greater than a MiG-21’s, but lesser than a Mirage-2000 thanks to smaller size), ease of maintenance, performance (turn rates instantaneous and sustained, climb rates, etc.), range, etc. most of which (except size) would be in the same ballpark as the Mirage-2000.

    and this would’ve been based on original Mirage-2000 data since the ASRs were drawn (and revised, such as the deletion of the R-60 and its replacement by the R-73 which caused a good deal of re-design) in the mid-late 1980s, when the IAF had its Mirages in service for half a decade. Anyhow, except for avionics upgrades, even now the Mirage-2000-5 retains the nimble airframe and performance of the original Mirage-2000. unlike the F-16, the Mirages have not been subjected to major thrust increases or major payload increase, so the performance should have remained quite the same.

    also, the Mirage was used as a benchmark quite early in the test program. I remember how a test pilot had described the Tejas’ landing speed as being lower than that of a Mirage-2000 and described it as being easier to land. the cockpit was noisy at that time and it was subsequently taken care of.

    May be someone meaning to write 5,600 kg for LCA put down 6,500 kg instead. Its a simple mistake that can so easily happen and get through different checks.

    seems the most likely scenario. the weight could hardly have grown overnight by a 1000 kgs; they had after all shaved off over 360 kgs from a TD to a PV to bring it down to earlier design intent levels.

    So one is not correct! Either the gun-system of the MiG-27 is in a safe distant from the inlets and the IAF pilot is wrong about the cause of the engine loss or he did not operate the MiG-27 in the correct way, when not.
    The third option is, that he lost the engine through AD. Running twice the same ground target does rise the possibility to become a victim of a manpad manyfold.
    What is your assumption about that?
    “I then eased out of the dive. As I went to the flares, I felt a backward jerk due to sudden deceleration.”

    the court of inquiry that investigated the reasons for the crash concluded that it was due to an engine flameout due to gun-gas ingestion. are you suggesting that based on your half-baked information and knowledge of this scenario, you’re in a better state to actually infer the reason for the crash? :rolleyes:

    there was no reason to hide if the MiG-27 had been shot down by a Stinger or ack-ack. A MiG-21 that went in to rescue the downed pilot was shot down and this was thanks to a Stinger missile, not a flameout- they could’ve claimed that it too flamed out if they were basically trying to coverup.

    GarryB has also explained in another post how even though the muzzle of the cannon is a bit behind the intakes, but during a dive and fire, the amount of gun-gas generated could easily allow for a fair bit to enter the engine, causing compressor stall.

    Wellknown footage of a fire-work display. What a pity, because it does not show the reality. Two retired Sukhois were prominently displayed and some extra fuel added around those. It had been more intresting, when the real damage from gun-fire had been shown at the remains from that after a more realistic strafing run. In that footage the fuel was ignited, when the first rounds hit the prepared ground in front of the target fuselages.
    It seems there is world-wide behavior to please the crowds or higher military with such Hollywood staged fire displays.

    it was a post to show the MiG-23s underbelly getting covered by fire and smoke at the time of it firing its cannon, as GarryB had mentioned in his post. a pity that you did’nt see that and instead look at the destruction of a few heavily fueled Su-7s.:rolleyes:

    On the face of it, an engine swap for the entire MiG-27 fleets looks like a waste of the Indian taxpayer’s money. Admittedly, some of these airframes are fairly new compared to the long retired Russian MiG-27 fleet, but as a single role, relatively short range type, the MiG-27 looks increasingly obsolete.

    Instead of engine swap with very modest gains, it would be better to fund a single multirole type to replace both the MiG-27 and Jaguar. The IAF has far too many times different types of limited capability fighters – and far too many aging airframes.

    It would not be unreasonable to double the number of airframes in the MMRCA program to 250+ so that high operating cost, aging types such as the MiG-27, Jaguar and early model MiG-29 could be replaced earlier than otherwise might be possible.

    since you’re very concerned about India taxpayer’s money, just to let you know, this project has not been authorized for the IAF as yet..this is something the engine bureau is doing on its own to prove the soundness of the concept of swapping the Al-31F-3 in place of the R-29.
