    Whats that ice-cream cone?

    I would agree with Danrh that the cone is probably ECM related. As for the cone shape, could this have been adopted – at least originally, e.g. on Russian and Dutch subs – with the idea in mind that the mast should be able to penetrate ice? Or is the shape solely a function of the ECM-equipment itself (antenna listening “up” and “around” from just above the water)?

    Notice something……looks like the MLRS you get on the 516….

    Yes, same launch system. Question is whether it is firing the same rocket or something of larger caliber (possibly steerable as the rocket in the pic has fins in the middle, which is unusual for a MLRS-rocket).

    Well I would think the Range of ****il cannot be increased any further without modifying the basic structure , Infact the new VLS ****il ( on P-15A ) will have a lesser range ( about 35 km seems to be the FC limit ) but higher speed M 4.5

    For India the ideal way to approach is the help/join russia develop a Naval variant of S-400 , I think as of now Aster is high on the mind of IN but long term solution would be to jointly develop S-400 variant . If one thinks about buying S-400 for the Air/Land forces then one can conceive an idea of Common Missile for all three Defence forces.

    Look at Europe now they are developing a Land Based Variant of Aster-30 (SAMP/T ) with ATBM characteristics , Thats the way to go.

    Emmm…… Seems Like No One Has answers to my questions :rolleyes: .

    On the basic Shtil missile you could employ a new, more compact rocket engine and a greater volume of higher energy propellant to increase range without modification of the missile frame. But perhaps the Russians have already done this and translated the advantage to speed instead of range.

    As for a really long range version, best would probably be to add a large booster-sustainer stage to the basic missile (compare Standard ER). A simple and cost effective solution may be to take the engine and propellant portion of another of another Shtil missile and use it as booster-stage.

    This ‘Shtil ER’ could work well for the VL version of Shtil: all that is required is that the VLU can take ‘standard’ as well as ‘long’ missile canisters. And otherwise, you’ld need VLUs of different length (compare MK41, which is available in modules of different length).

    Personally, I think a VL SAM version of AA12 Adder would be a good complement to, possibly even an alternative for SA-11 Gadfly/SA-17 Grizzly in both land- and sea-based applications.

    How would this be as alterntive to Sea King and Helix AEW versions?
    Manufacturers Designation: EH 101
    Development History:
    EH 101 Series 112 AEW (Heliborne Early Warning or ‘HEW’) version for Italian Navy. Eliradar APS-784 radar in much larger under fuselage radome. T700-GE-T6A engines.
    EH 101 Compound lift Projected version with stub wings above the cabin, flight refuelling probe, for long-endurance AEW mission for RN.

    Paris – 15th June 2003
    The first Italian Navy EH101 in the Heliborne Early Warning (HEW) configuration made its public debut at Le Bourget 2003.

    The Italian Navy has to date ordered 20 aircraft with 8 configured for Anti-Submarine Warfare (ASW)/Anti-Surface Warfare (AsuW), 4 for Airborne Early Warning and 8 for amphibious operations. The contract for the last batch of 4 aircraft is expected to be awarded at the end of 2003 bringing the Italian Navy order for EH101 to 24. Deliveries of the ASW/AsuW aircraft have now been completed.

    The HEW aircraft, equipped with a pulse-doppler surveillance radar and APS 784 antenna housed in a 3m diameter radome, is able to detect and track multiple air targets even if embedded in ground or sea clutter, track surface targets and perform real-time surveillance of air and surface threats. Secondary maritime roles include over-the-horizon targeting and surveillance, AsuW and search and rescue. The mission sensors are controlled and integrated through the Mission Computer System (MCS), the core of which comprises two Mission Computer Units (MCUs).

    EARLY WARNING AND ASV/ASW AIRBORNE RADARS
    HEW 784: X-band, digital multimode, pulse Doppler radar for Air-to-Air and Air-to-Surface, 360° surveillance developed for the EH 101 helicopter for the Italian Navy.
    APS 784 radar produced with Galileo Avionica Surface Systems for the Italian Navy version of the EH-101 helicopter.

    The MCS conducts control of mission sensor systems, processing of tactical data received from sensors, collation and data fusion of tactical data, display processing for presentation of tactical data to operators, processing of operator control functions, stores management, data link processing, tactical aids and fault detection and reporting. The MCS manages the operator’s interface at crew station level to aid the crew in the execution of the mission. These functions include tactical database management, tactical aids, tactical navigation management and data link management.

    The EH101 HEW is also equipped with a full suite of ESSM, ECM and ECCM interfaced to the MCS.

    AFAIK aircraft carriers are useful either to protect faraway territories (colonies, islands, etc) or for imperialist-type projection of power to remote places. (imperialist not meant as a judgement, as in policing the imperium).

    To my knowledge Brazil doesn’t have many overseas colonies to defend, nor does it have the realistic means of launching an imperialist-type expeditionnary force again overseas countries.

    Well, what about protection of key shipping lanes (oil, major im- and exports) outside of land-based aircover? Carriers also play a role in that game. That’s one reason why WWII saw the introduction of MAC-ships and escort carriers.

    Those are not Fouga CM-170 Magisters, but Fouga CM-175 Zephyrs. It was a specially-built version for the navy.

    Thanks, learned somthing new. Where this an expensive development? If not, I see it as a point in favor of developing “AMX-naval” or “Goshawk-200”.

    Found this picture in the TOI of some cadets at INS Shivaji being taught something. Sorry for the low quality of the pic .(I know most of you guys are probably spoilt by the amazing pics from Aero-India 🙂 )

    Look like a lesson in turbine maintenance

    Benefits of the A-7 also include a small deck footprint (folding wings) and a engine similar to AMX (both Rolls-Royce Spey). Also it has the same undercarriage as the S-3 Viking which might help with spare part issues if the Navy wants to operate the S-3.

    In my opinion the most sensible solution would be to go STOVL and buy some ex Marine AV-8Bs.

    The most interesting solution would be to join up with Russia, India, and China and develop a new range of carrier aircraft.

    Can’t understand why Brazil would not cooperate with India on both a new carrier and naval version of LCA.

    Portugal has dropped its A-7 fleet a few years ago (maybe 99, don’t remember for sure)

    Indeed, you are correct, A7´s last flight in the Portugese air force was on 10 July 1999.

    Yes, but isn’t this a new version of the 950 with perhaps a lower load of torps due to the placement of the VLS? :confused:

    AFAIK there simply a VLU insert in the rear, there’s no reason to change the front part of the sub, including nnumber of tubes and reloads.

    I’d certainly prefer the AV-8 to the British models.

    AV-8A = original wing and cockpit = older UK gr-versions
    AB-8B = rewinged and revised cockpit = newer UK gr versions

    Essentially you are saying you prefer the newer Harrier II to the original Harrier. This has little nothing to do with US and UK versions as they don’t differ much (mainly in avionics).

    According to Russia’s Arms 2004 the Amur 950 carries 12 torpedos.

    I figured as much. Thank you for checking though.

    If harrier/stovl is out of the question, the only viable cooperative program is Indian ADS and naval LCA. Or, perhaps, a cooperation with Italy’s Fincantieri for the hull, and then some aircraft option. Izar? Possible, but what experience do they have to show for themselves?

    Short of Rafale, F18, Mig29, Su33, here’s another possibility: the supersonic YA7 Plus.’

    http://www.eichhorn.ws/assets/images/ling_temco_yought_ya7f_corsair_II.jpg

    The high costs of the originally planned close air support version of the F-16 caused congress of US, the US Air Force began with the search for a substitute solution.

    In May 1987 LIV received the order to convert two A-7D of the air national guard equipped with the night flight system LANA (Low Altitude Night Attack) into the version A-7 plus.

    The airplanes received the prototype designation YA-7F and on their suitability for close air support and isolation of the battlefield from air were tested. The first enhancement of combat capabilities for nearly 20 years

    The modified engine compartment of the YA-7F can take up the afterburner engine FlOO-PW-220 von Pratt & Whitney or Fl 1O-GE-100 of General Electric. The trunk became extended over 121 cm. It received a new tail cone, wings and flaps revised, in order to shorten the landing distance. An onboard APU makes the airplane independent of external power supply, and finally also modern avionics equipment was inserted.

    However, the interest lacking of the US Air Force showed up in the late first flights on 29 November 1989 with the F110 and on 27 April 1990 with the F100. If necessary monthly 6 or 7 by altogether 337 Corsair II are to be reequipped to a unit price of 6.3 million dollar on the conditions A-7 and into that next millenium inside in the employment remain.

    …supersonic Corsair

    Would be feasible if Portugal, Greece and Thailand would also want to modify their A7 fleets to this standard. Then perhaps
