    I think there has been no news after November 09 when both engines were tested @ HAL based in Bangalore.

    I assume there are plans to equip the RAF/RN’s F-35B STOVL fleet with buddy re-fuelling stores?

    If not I feel this would be an absolutely huge mistake and make the air group significantly less flexible and frankly safe then it could be.

    Thoughts???

    Good Idea. Lots of potential. 🙂

    Two options:
    1. stealthy external fuel tanks
    2. fuel tanks inside the weapons bay

    Mobile Nuclear Reators create jet fuel and geenrate power

    Compact nuclear reactors can now make Jet Fuel in addition to generating power aboard USN Carriers.

    Here’s the link. The benefits of R&D are amazing.

    I’m curious as to how sophisticated russian aircraft-testing infrastructure is? How much is India paying to use those facilities for the SARAS program I wonder. 😎

    At the end of the day its nice for India to have an ally like Russia where significant aircraft flaws can be reproduced in sophisticated test labs and rectified quickly. 😎

    This very, very interesting graphic from Richard Beedall’s Navy Matters summarizes the results of the F35 versions: effective performances against requirements:

    That graphic maynot give the complete picture. You need to have cost comparisons between the F35A and C, g-rating/sustained turn-rate differences due to the folding wing, strengthened fuselage, beefier landing gear etc on the F35C, etc …

    Then maybe a clearer picture will emerge. i hope UK gets the best aircraft. 😉

    SARAS started off as a joint venture between Russia and India in the mid 1990’s. It was supposed to be a safe project. But Russia pulled out in the late 1990’s citing financial difficulties.

    So the project started off soundly but things changed. Problems crept in … NAL was stuck ..too late to back out. They tried to stick to project milestones without compensating for loss of russian design knowledge…. End product was nowhere near perfect.

    I consider the crash of the 2nd prototype as pilot error. The third protoype should get this program back on track.

    I am not sure about that. SARAS is a unique design. Its not a conventional turboprop or a turbofan. Very few planes in this class have gone into production successfully Ex: Piaggio P180 Avanti II Twin Engine TurboProp.

    MTA Update – dated Mar 2010.

    Quote from the above article:

    “The assembly of the first prototype is expected to begin in 2010 and a total of 5 prototypes are proposed to be built. (3 for flight tests + 2 for ground tests). The first flight of the MTA is expected in 2013 with deliveries starting in 2015 at the earliest.”

    Its not easy to build a pusher configuration. I think the fact that India even attempted something this complex is a credit to them.

    Regarding F35A vs F35C:

    A larger wing has advantages and disadvantages. If there were no downside to a larger wing, the F-35A would have a wing as large, if not larger than the F-35C’s. The main reason the F-35C has a larger wing is to meet its carrier approach speed requirements, if I’m not mistaken. If the US Navy didn’t have all of those slow speed landing requirements, the F-35C would most likely have smaller wings. A larger wing creates more total drag, so don’t automatically assume that larger wing = more range. Aircraft design is not a simple process… even for a subsonic, prop-driven aircraft. A stealthy, supersonic fighter is a very complex design problem. The wing area of the F-35A was no doubt well thought out. Give Lockheed Martin engineers a little more credit. They knew what they were doing.

    Actually, the RAF isn’t such a great supporter of the F35 at all. And i’m not sure about their preference going to the F35B either, since they were said (when money wasn’t so much of a problem) to be considering buying a bunch of F35C to use as a Tornado replacement in Deep-Strike role thanks to their range, stealth and weapon load. (in other words, they wanted them in exchange for the dead FOAS requirement)

    I am not sure about this. What is the difference in cost between a F35A and F35C. I think its quite a bit.(15-25million$).

    If the RAF didn’t want the STOVL F35B the obvious choice would be F35A. Far lower unit costs and hence can be purchased in more numbers.

    (If we go by your logic, all customers of the F35A would just pitch for the F35C and drop the F35A).

    The RN on the other hand cant use the F35A.

    Disagree. RAF doesnot have an F35C option. RN does.

    1. The propulsion is electric, & IIRC has space & weight allocated for additional turbines. Power is not a problem.
    2. Although no steam catapults are being built at present, resuming manufacture is easy, & that will be true as long as the current steam catapults are kept in use.
    3. Wrong question. It’s not just the RN, but also the RAF. One huge advantage of STOVL is that land-based pilots can qualify for carrier operations quickly & relatively easily, enabling a joint force. Both the UK & Italy are adopting this model, with air force F-35Bs available to reinforce the carrier air groups when needed.

    1. Ok. Good job by the designers.
    2. Not necessarily steam launch. Land-based EMALS system has passed tests. link
    3. I am not referring to the RAF. The problems of the RN are unique to it and can’t be combined with the RAF. Only the RN has this option between F35B or C.

    Note: I am aware that the RAF prefers the F35B. This is a different topic and very interesting indeed :). Howver, I would prefer if this doesnot cloud this naval discussion.

    If I missed out on any please update me. Looks like HAL will need to go on a hiring spree, both for technicians as well as engineers and this decade will see HAL’s workshare go up tremendously.

    75 HPT class trainers. Probably only assembly of CKD kits.

    What about the Mig29K’s?
