    STOL or CTOL dirt-strip-capable aircraft also don't have to be located far from front lines, but very few, if any, fighter aircraft are dirt-strip-capable. And I don't know any VTOL fighter (or "fighter") that can take off with 100% fuel and full air-to-air weapons loadout.

    You can design one such aircraft very easily provided you know how to beat gravity.

    Lol ... Easy for you to say you're not the designer who needs to do about a hundred pages of mind numbing calculations.... Analysing all computer test data ... Finding the topology of non conformal shapes .... Worst of all the eternal question"how do you make it lighter?"..
    problems in vtol design
    1 wings especially ones for supersonic use provide heavy drag and are also unstable in wind
    2 designers nowadays go for a RSS system ,better known to pilots as fly-by-wire, this tends to shift the cg from the geometric centre which causes further instability

    Vstol ji please note the sea harrier does not suffer from any of these problems it had a high aspect ratio wing was designed to be subsonic and the centre of gravity was where it should be right in between the two lifting fans

    NATO studies in the 1970s showed that their air forces would have been destroyed like the egyptian air bases were in 1967 for such a reason in 1991 the US rendered useless the Iraqi air bases from the first day of the war


    Contrary to what people think the VSTOL variant of F-35, has a great advantage and very complex engine but addding a touch of survibility no other jet has with exception of Harrier.
    it is a reality that in any major war attacking the air bases makes the difference, Germany when was attacked and bombed by the allies, they deviced aircraft like natter, in the 1950s several aircraft were designed with VSTOL, the only succesful aircraft of those was the harrier, since J-31 has DSI its ability to fly faster than F-35 is none, the F-35B has no disadvantage over J-31.

    If you navalize J-31 it will need larger aircraft carriers, this means once the aircraft carrier is lost, you lose its base.



    F-35B is a great advancement since it can get supersonic speeds, and yes ideally the best fighter should had VSTOL if not STOL but for that you need TVC nozzles like F-22


    A V/STOL jet always gives you the ability of more adaptability in deployment from smaller aircraft carriers or ships and take off from damaged runways

    china copies is just a tech tranfer strategy to catch up faster without R&D higher costs

    Smart actually, also they can tweak the design to fix the problems.

    VTOL is a pest to make work. It is hard to make a VTOL really good.

    Underground air bases and STOL dirt-strip capable aircraft are another option, one which does not sacrifice aircraft performance in combat.

    The F-35 Lightning II joint strike fighter (JSF), is being developed by Lockheed Martin Aeronautics Company for the US Air Force, Navy and Marine Corps and the UK Royal Navy.

    The stealthy, supersonic multirole fighter was designated the F-35 Lightning II in July 2006. The JSF is being built in three variants: a conventional take-off and landing aircraft (CTOL) for the US Air Force; a carrier variant (CV) for the US Navy; and a short take-off and vertical landing (STOVL) aircraft for the US Marine Corps and the Royal Navy. A 70%-90% commonality is required for all variants.

    The requirement is for: USAF F-35A air-to-ground strike aircraft, replacing F-16 and A-10, complementing F-22 (1763); USMC F-35B – STOVL strike fighter to replace F/A-18B/C and AV-8B (480); UK RN F-35C – STOVL strike fighter to replace Sea Harriers (60); US Navy F-35C – first-day-of-war strike fighter to replace F/A-18B/C and A-6, complementing the F/A-18E/F (480 aircraft).
    F-35 Lightning II Joint Strike Fighter (JSF) - Airforce Technology

    F35 will replace or combine about 11 other types of aircraft, and will be used to introduce more advanced technologies. Its designed that a pilot can walk out a Flight Simulator that is identical to the experience of flying the F35.

    it is quite awkward for a top secret project like this to be leaked in public so easily for china.it has always tried to catch up numberwise wtih US and not techwise and thats why they are now stuck with more than 500 junks in their air force.this is not even a prototype as afar as a stealth one is concerned.this projects ambitions not quality.these are basically publicist strategies on the part of the manufacturers to make a statement to unconditional buyers like pak that they are a counterveiling force to US.replacing the junks with their j10s and making stealths at same time will much time than estimated even for ambitious china.so i dont see any reason for india to be paranoid .it should slowly build up indigenous systems so that in event of delivery ther are no hiccups .and as far as tejas is concerned ,it has its own reasons for delays.but whether in production or not.it has given full self sufficiency of india in aerospace technology that is state-of -the-art.and the ucav will be a testimony to that.
