    There were several factors involved in closing down the two fora including the flak we used to get. However feel free to contact me or post any issues you have on this thread however keep it civil. I will be listening!

    Can you share those factors with us?

    Is it possible to close the Army and Navy forums but make them available in the archives?

    Would it help to have a general military discussion forum instead of the Missiles and Munitions Forum too?

    Does it have anything to do with the low numbers viewing?

    Compared to the Missiles and Munitions Forum the Army and Navy forums had high viewing figures :confused:

    Trouble with an EJ200 powered STOVL plane is that it’s either quite a bit smaller than a Harrier, or it has to be twin-engined. The EJ200 is a great engine, but it’s not that big. Is a Hawk size plane credible? A STOVL Mako? And that would be struggling to bring back weapons for a vertical landing. You’d have severe limits on radar antenna size, range, payload . . . No, too limiting. Got to be two EJ200s. Nothing wrong with that in principle, but I think it’d complicate the FCS for vertical flight.

    Fair comments, but I was thinking of a standard EJ200 combined with a lift jet or a advanced EJ200 development with a higher thrust rating.

    Info on more powerful EJ200 developments for the Typhoon can be found here http://www.eurofighter-typhoon.co.uk//Eurofighter/engines.html

    I totally agree with sealordlawrence, removing the Army and Navy forums is a big step backwards and will result in a lot of threads going wildly off topic as we start discussing tanks and ships in the wrong place.

    Please reconsider this decision 🙁

    Giuseppe Garibaldi is probably a better balanced design, more weapons, better propulsion, etc.

    Principe de Asturias is based on the Sea Control Ship which I really like, but it’s a design that’s supposed to be mass produced (quantity versus quality).

    Here are a couple of pics from the Lets see some mini/small carriers thread http://forum.keypublishing.co.uk/showthread.php?t=40890 the book cover is mine and the I400 pic is Francois5’s and a good one from Matej.

    That’s an awkward looking location for the -120.

    I agree, it’s a standard fit though.

    Old thread but still relevant, every time I see this I can’t help but think of all the people killed in crashes unnecessarily 🙁 😡

    Anyone know if the Israeli airbag system is operational yet?

    OK, what about this –

    Configuration like an F-35, but two EJ200s in place of the single F135, with smaller versions of the F-35 swivelling jet pipe. It’d need a new power take off from the engines, there being two of ’em, but that saves worrying about the USA vetoing use of the R-R N. America designed one in the F-35. With twin nozzles at the rear, would it need the auxiliary side thrusters of the F-35?

    Sensors & weapons as for Typhoon. Doable? If so, any guesses as to cost & timescale? Nobody’s ventured any opinions on either so far, for any options.

    It’s probably possible but it sounds very complicated and expensive.

    In my opinion, a Harrier III will have to be a simple Harrier II update or a new low cost and lightweight design that uses a EJ200 based powerplant to have any realistic chance of funding.

    A lightweight Boeing X-32 style direct-lift design would be my choice 🙂

    It would look similar to these pics JAZZ posted.

    Stupid question: Could a “Harrier III”, re-use a configuration similar to the Yak 141’s ? A twin-tail, and the rear of the Pegasus engine being modified with an afterburner ? Why not ? 😉

    Take a look at page 181 of this document http://techreports.larc.nasa.gov/ltrs/PDF/NASA-95-tp3542.pdf

    It shows a ASTOVL fighter with features similar to the Yak 141 but uses a advanced Pegasus type engine called Highly Integrated Deployable Exhaust Nozzle or HIDEN (pronounced hidden 😉 ).

    I think the P.1216 was the perfect project to replace the Harrier by a “pure” british aircraft. Its really a pity that even the Falkland war couldn’t convince Miss Thatcher to fund the project…
    Have you seen the X-wing P.1214 ? awesome project!

    Tony Butler’s British Secret Projects books are full of great V/STOL designs, but unfortunately Mrs Thatcher was firmly ”buy American” when it came to the Harrier replacement. It’s a shame the US only wanted a close air support aircraft at the time.

    Something like the P.1216 could be the basis of a Harrier III but I think a simpler design would be a better choice.

    Oblique wing is ideal for a long range recce or standoff jammer airplane. With wing unswept, it takes off & lands at low speed from short airfields and can loiter for a long time while on station. Sweep the wing and it goes fast to reduce transit time from base to it’s operating station or to put distance between itself and a threat.

    It’s also possible to make a pivoting oblique wing mechanically simpler and lighter than normal swing wings and it’s probably the only way a flying wing will go supersonic(?).

    I wonder if the wing and engine can be in a fixed position and the sweep angles can be controlled by aerodynamic surfaces and thrust vectoring? This could be a lot lighter and cheaper than a mechanical sweep system.

    Could Sea Harrier FRS1 safely land vertically with two unused Sea Eagles attached in hot weather condition? I bet FA2 couldn’t.

    It probably could, landing at high weights in hot weather conditions isn’t impossible for the Sea Harrier but doing so causes the engine to wear out faster.

    Conventional Trident missiles could be carried alongside Tomahawk cruise missiles on the USN’s Ohio class SSGN conversions.

    I believe cluster bombs full of steel rods were used during operations in Iraq. Something like the Common Aero Vehicle would be a good way to deliver them http://www.designation-systems.net/dusrm/app4/x-41.html
