    PdA FOR SALE?!? Wonder who’ld be interested….?
    There should be takers for OHP e.g. Taiwan, or e.g. Turkey, Egypt, Pakistan.

    The Be-200 can operate from either a 1,800 m long runway or an area of open water not less than 2,300 m long and 2.5 m deep, with waves of up to 1.3 m high

    No it is way behind in capcity to Shinmaywa at least for amphibious aircraft

    DO follow the link to ShinMaywa I provided, where it lists comparison:

    I’ve not commented on the relative performances, just that I think the offer to IN is daft, considering P8i induction.

    Shinmayawa SS3

    A new entry from Japan for Indian navy.
    Amphibian STOL aircraft currently pitched by Japan, look very promising and useful.

    Hilarious. Wonder when we’ll see Beriev B-200 entered…

    This is what Trishul blogspot had to say about the article on INS Vikramaditya and Pr.11356 batch 2.

    one interesting point I missed earlier was in the opening para of the article itself…

    who is this “our” mentioned in the article w.r.t to the joint development of the combat command information system?

    At least for me it was somewhat new info…. If this combat management system or Combat Command Information System (CCIS), as Russian developers terms it, is common for all the Talwar class frigates and the Shivalik class…..it would mean Indian Navy have at least 5 ships that is completely networked. This now makes me believe more that Talwar class and Shivalik class are going to be the main surface combatants of the INS Vikramaditya group and the Delhi class is going to be left out. A fleet that is completely networked would be the better option anyway.

    Any thoughts and info on the above quote from USC publication?

    What makes you think the CCIS on the P15 Delhi’s in not compatible, or cannot be made compatible during MLU? Follow on Kolkata class P15A will surely take mny of the same systems as P17.

    More likely that they took Mig21 as starting point and beefed it up to a 2 engine version

    In the case of the Z-11, why not just buy the original? It cannot be that much more. The Dhruv also looks much more capable. Two engines vs. one (depicted in the photo), rear-loading ramp can make a difference. Ecuador also operates the Dhruv

    http://fuerzaaereaecuatoriana.mil.ec/new/

    And the Dhruv is nothing like the MBB/Kawasaki BK177 or the EC-145 that (like Dhruv) is a development from it ?

    in reply to: AMX vs Harrier for usefulness in a carrier #2313205
    Wanshan

    well, since we’re at it:

    – navalizing the AMX would cost a lot… if you can put the EJ200 in it,k you can in the A-4 as well… just bring some modifications like the radar used in brasilian F-5s, some more avionics and you can get a quite decent light naval fighter (modernised A-4)…

    that would be the cheapest option

    other naval options are:

    – Rafale, needing a small extension at the end of the catapult (was done and wouldn’t cost much) but the catapults may be somewhat “light” to launch it at full load

    – Hornet, but there aren’t many available around as it’s not in production anymore, and buying used ones they’d start whezre they are today with the A-4, albeit with a more modern platform, but still… it would require upgrades right now….

    – SH – no; it’s too big, and modifying the carrier would cost really too much (lifts, catapults, etc… )

    – navalised gripen – probably too costly as it would need to be developed for a very small production run – not worth it

    – navalised AMX – same as the gripen, with the fact that it’s definitely not an air superiority fighter in any case

    – harrier (any sort) – forget it. it’s not in production and would need heavy modifications on the carrier to be able to operate from there, with more restrictions than the current A-4 has

    – Su-33 – same thing, it has nothing to do on such a small carrier, what’s more a CATOBAR one

    – Mig-29K – the size is closer to a usable one, but would need modifications for catapult use, increasing its price… how interesting for the brasilians can be to buy it, considering the serviceability they can expect, as well as the weapons that are absolutely not common with what they use today, remains to be seen

    basically, they either stay with old aircraft – modernise the Skyhawks, or buy used aircraft…. the only option for new aircraft would be Rafales which, in fact, could be interesting from another PoV: if they buy Rafales for their Air Force with the ToT coming with it, they’ be easily capable to maintain and modernize their navy aircraft since, with the exception of some structural parts, it is exactly the same aircraft

    Patrolling and defending/blocking of the EEZ from enemies surface combatant ships and vessels. Is what I meant. “SSK are basically ideal for the defence of the EEZ”

    Within the exclusive economic zone (EEZ), the coastal state has sovereign rights for the purpose of exploring, exploiting, conserving, and managing natural resources, both living and nonliving, of the seabed, subsoil, and the subjacent waters and, with regard to other activities, for the economic exploitation and exploration of the zone (e.g., the production of energy from the water, currents, and winds).

    Within the EEZ, the coastal state has jurisdiction with regard to establishing and using artificial islands, installations, and structures having economic purposes as well as for marine scientific research and the protection and preservation of the marine environment.

    Other states may, however, exercise traditional high seas freedoms of navigation, overflight, and related freedoms, such as conducting military exercises in the EEZ.

    Article73

    Enforcement of laws and regulations of the coastal State

    1. The coastal State may, in the exercise of its sovereign rights to explore, exploit, conserve and manage the living resources in the exclusive economic zone, take such measures, including boarding, inspection, arrest and judicial proceedings, as may be necessary to ensure compliance with the laws and regulations adopted by it in conformity with this Convention.

    2. Arrested vessels and their crews shall be promptly released upon the posting of reasonable bond or other security.

    3. Coastal State penalties for violations of fisheries laws and regulations in the exclusive economic zone may not include imprisonment, in the absence of agreements to the contrary by the States concerned, or any other form of corporal punishment.

    4. In cases of arrest or detention of foreign vessels the coastal State shall promptly notify the flag State, through appropriate channels, of the action taken and of any penalties subsequently imposed.

    Originally, the aircraft was designed to have a pressurized cabin. However, it was found that the cabin’s seals were often breached when the wings were moved into storage position, or when the aircraft flipped upside down and slammed into North Carolina. Designers ultimately decided to scrap the cabin pressurization system when they ran out of technical skills. In its production design, the V-22 does not have a pressurized cabin, so at altitudes above 10,000 feet the crew must either wear oxygen masks or hold their breath.

    http://uncyclopedia.wikia.com/wiki/V-22_Osprey
    http://www.fighter-planes.com/info/v22_osprey.htm

    So, no not currently pressurized but pressurization does not have to start from scratch. Although pressurization may have only applied to the cockpit area, with everyone else using masks.

    Why the need for 76mm guns anyway? The Vikramaditya isn’t an LHD; for personal defense against missiles a good CIWS would suit it best. If not Kashtan I’d strongly recommend the Pantsir-ME when it gets cleared for export.

    Well, who said NEED. The only NEED is defensive armament. THen looking at what’s available. The 76 Oto is usefull as longer range AAA and on the plus side, it can be and is made in India. AK630s by contrast would be imports. And by themselves not a CIWS. ‘A good CIWS’ in the IN means at least a pair of VLUs for Barak missiles plus a pair of AK230 or AK630s and a pair of Elta radar fire directors….

    I think Kashtan (and like) was ruled out for this ship quite some time ago already…. it certainly isn’t installed on any of the above pics, while the remainder of equipment does seem to be installed. Hence the armament speculation in the first place..

    ps: USN LHA/Ds are intented for use as sea control ships as well, embarking some 20 Harrier 2 and not much else in that role.

    But lack of medium to long range missile is not good.

    By the 76mm naval gun do you mean to have it for naval gun fire support or for using AD shells?

    USN begs to differ re. the missile, I think. As do most operators of Harrier or F-35 capable LHA/D (RAM, mostly, if a SAM at all)

    76: No, just a big a$$ AAA/ASuW gun that is available. If need be it could be combination with Oto Melara’s Dart/Davide/Strales. I think there’s just the two stern positions where you could park a gun on Vikramaditya now…

    I think that Brazil is more likely to build (with foreign assistance) a CATOBAR carrier or two than buy a third hand STOBAR ship.

    Depends on the money situation, I would think. But those ‘third hand’ ships today are pretty much restored to new condition so third hand is actually second hand (although third owner)

    No, they’re still building two or three. But no more.

    Three. The Navy expects each ship to cost nearly $3.8 billion. Including research and development, the cost grows to $7 billion apiece.
