    You didn’t get the connection? Erieye in standard platforms only has a few operators and is dependant on ground control, so Pakistan chose a bigger platform(Saab-2000) for greater capability. I proposed the same thing for the Hawkeye.

    duh! WHY DID YOU THINK i POSTED ABOUT ERIEYE IN THE FIRST PLACE? (YES, BECAUSE OF THE VARIABLE NUMBER OF OPERATORS, RELATED TO THE AIRFRAME ADOPTED AND THE USE OF GROUND CONTROL) wHAT DOES 360 DEGREE COVERAGE HAVE TO DO WITH THAT?

    The Erieye does not offer 360 deg coverage.

    Irrelevant to the question of maritime surveillance capability (what does it – coverage – matter when you fly racetrack patterns, mainly looking sideways anyway). Also irrelevant to the question about the number of operators.

    I know about the Erieye, but it’s not operated by any navies and I doubt it’s as fine-tuned for maritime scanning as the Hawkeye is.

    I figure overland ops are more demanding than overwater ops. Anyway, Erieye comes with a maritime surveillance mode.

    Saab is providing a “third-generation” version of the radar, says Soderstrom. “We have six customers and none has exactly the same radar.” In particular, its sea surveillance capability is better. Saab says that at 25,000 ft., it can track jet skis to the horizon. Altitude resolution is also improved. Four aircraft can sustain two patrol stations around the clock for 30 days.

    As we know, the only AWACS system in the world purpose-built for naval use is the E-2 Hawkeye. Of all the fixed-wing AWACS it’s the one best optimised for maritime surveillance, and as such the US Navy(and presumably other naval operators) will be relying on it for all their AWACS needs for the next 40 years or so.

    tsk, tsk!

    “The E-1 Tracer was the first purpose built airborne early warning aircraft used by the United States Navy. It was a derivative of the C-1 Trader and first entered service in 1958.”
    http://en.wikipedia.org/wiki/Grumman_E-1_Tracer

    “the Grumman E-1 Tracer… was a modified version of the venerable the S-2 Tracker piston-engined anti-submarine warfare plane … The E-2 and its sister, the C-2 Greyhound, are currently the only propeller airplanes that operate from aircraft carriers…. the E-2A Hawkeye, was the first carrier plane that had been designed from its wheels up as an AEW and command and control airplane. “
    http://en.wikipedia.org/wiki/Northrop_Grumman_E-2_Hawkeye

    “The C-2 Greyhound is a twin-engine cargo aircraft, designed to carry mail and supplies to and from aircraft carriers of the United States Navy… The C-2 Greyhound, a derivative of the E-2 Hawkeye, shares wings and power plants with the E-2 Hawkeye, but has a widened fuselage with a rear loading ramp.”
    http://en.wikipedia.org/wiki/C-2_Greyhound

    However, for those countries operating the Hawkeye from shore-based facilities it has the major drawbacks of a)Short range and b)Small size and only three operator controls; which are an acceptable compromise on an aircraft carrier but a waste on land.

    Are these critical factors?

    Ever looked at the Ericson EriEye? Sweden’s ERIEYE use a platform (S100 Argus a.k.a. Saab 340) with only 3 operators. However, if using the SAAB 2000 – as Pakistan has elected to do – it can carry up to 9 operators. Let alone using an EMB-145 like BRazil does. The Erieye Ground Interface Segment (EGIS) provides a two-way exchange of data between the airborne AEW & C platform and a ground-based air defence network via an associated datalink sub-system, or on-board operators can control friendly fighters directly.

    So what would be the feasibility of integrating the E-2D Advanced Hawkeye mission suite on an MPA like the P-8 to provide a next-generation shore-based naval AEWC solution? Both the problems of range and operating consoles are solved, and the resultant platform would be very attractive for navies without aircraft carriers, like Australia.

    Sufficiently answered by other posters, I would think.

    I have heard that IDAF was outnumbered 2 to 1 in Bekaa valley, facing the latest MiG-23MLDs and Mig-29s yet managed to score a 85 to zip kill/loss ratio ? is this true

    I tried to research but found no substantiation for these claims, yes the IDAF score 85 forno loss, but I didnt find that they were so outnumbered or faced such latests types

    any thoughts

    Really, did you google anything at all?

    Reports of what happened next vary. It is generally accepted that in the course of the first attack against the Bekaa an 9 June 1982, the IAF destroyed 17 of the 19 Syrian SAM batteries and their radar sites, as well as 29 Syrian Air Force (SAF) fighters, without loss.15 The following day, the IAF destroyed the remaining two missile batteries. The SAF once more challenged the Israelis and lost approximately 35 more aircraft, again without downing an Israeli aircraft. By the end of July, Syria had lost at least 87 aircraft, while Israeli losses amounted to a few helicopters, one RF-4E, and an A-4 Skyhawk downed by a PLO SA-7.16

    The lopsided results of the battle stem from a number of factors. The most visible in any air engagement are the quality and capabilities of the weapon systems employed, especially aircraft and air-to-air armament. The IAF had a definite qualitative advantage in both. The primary Syrian fighter during the Lebanon War was the relatively obsolescent MiG-21, with considerable numbers of export model MiG-23s and Su-20s also deployed.23 The Israelis, on the other hand, were flying new-generation McDonnell Douglas F-15s and General Dynamics F-16s, as well as older but still effective McDonnell Douglas F-4s and Israeli Aircraft Industries Kfirs.24

    Other factors make the Bekaa Valley battle unique in the history of air power and limit its relevance. In addition to their qualitative advantage, the Israelis enjoyed numerical preponderance over the Bekaa Valley, outnumbering the Syrian Air Force by a ratio of about three aircraft to two.72

    The MiG-23MF, MiG-23MS and MiG-23BN were employed by Syria in 1982 during the Israeli invasion of Lebanon, it is said that around twenty six MiG-23s were shot down by the Israeli armed forces, the Syrians claimed their MiG-23MS and MiG-23MFs shot down at least two F-4s and five F-16s. In June 1982 the Syrian air force lost six MiG-23MF, four MiG-23MS and sixteen MiG-23BNs. However later that year, in December 1982, the Syrians recieved more capable and advanced MiG-23MLs. The Syrians claimed that their MiG-23MLs on 4 October 1983 shot down three F-15s and one F-4 without sustaining a single MiG-23ML loss.

    Third hit googling: “syrian air force”+”mig 23”

    The [Syrian Arab] Air Force, which was independent of Army Command, consisted of about 100,000 regular and 37,500 reserve officers and men. In 1985 its 9 fighter-ground attack squadrons and an estimated 15 interceptor squadrons totaled approximately 650 combat aircraft. Almost all combat planes were Soviet manufactured and included 50 MiG-25 and MiG-25R (Foxbat) interceptors and nearly 200 MiG-23S/U (Flogger) and Su-17 FitterK ground-attack and multirole aircraft. In 1986 there were reports that the Soviet Union had agreed to provide Syria at least two squadrons of the advanced supersonic MiG-29 Fulcrum fighter aircraft equipped with top-of-the-line avionics.

    salutations,

    how does the Shivalik class compare to the Talwar class, first in terms of the types of roles they are to do in the fleet, and their capabilities.

    Better ASW:
    additional VLU cells, e.g. for 90R missiles
    2 rather than 1 helicopter
    2 rather than 1 RBU 6000 launcher
    different sonar fit

    Possibly some qualitative improvement in close in AAW
    – 76mm oto melare versus 100mm AK-100
    – Barak + 2 AK630 versus 2 Kashtan (better missile, but fewer rounds?)

    Possibly some qualitative improvement in AShW
    Brahmos capability versus Klub only

    I finally found a pic of the model of the Admiral Gorshkov frigate. It seems the first vessel, at least, will have the Top Plate radar instead of Poliment-K.

    Yup, that would be the Talwar class.

    would Greece have the money to buy and would the Germans sell to Greece the unpopularity of the Greek bailout would indicate if the F122 more likely go somewhere else, Would Poland be interested in increasing its fleet

    The Gawron Class (Rook Class) or Projekt 621 is a class of multipurpose corvettes ordered by Polish Navy. Gawron Class is a variant of MEKO A-100 project developed by Blohm + Voss Shipyard in Germany. Construction of first ship of the class started in 2001.
    There were plans to build 7 Gawron Class frigates, but as of 2009, work has only begun on one ship, which is to be named ORP Ślązak (Silesian). The program suffered delays due to insufficient funding from the government and delays in chosing final weapons’ and systems’ configuration. On the 16th of September 2009 the hull was launched, but the program was suspended due to financial crisis[1]. The second corvette was to be named ORP Kujawiak (names of others planned to be built: ORP Krakowiak, ORP Mazur, ORP Kurp, ORP Goral (Podhalanin). Work has now resumed and the first ship should be launched by 2015 [2]

    http://en.wikipedia.org/wiki/Gawron-class_corvettes

    I doubt Poland has the funds for both Garwon class as well as additional other ships. But F122s instead of additional Gawrons might be an option. As would additional FFG7 frigates when they become US-surplus.

    I recently came across a collection of pics of the Vikramaditya’s construction. Browsing through them I found this pic of her superstructure:

    http://i40.tinypic.com/2d0ctns.jpg

    See the steel tower behind the main superstructure? I’ve seen that in various models of the Vikramaditya as well. I’m assuming it’s an aircraft control tower. If that’s what it is, does that mean the Vikramaditya will be having a double island superstructure like the Queen Elizabeth class to facilitate better air traffic control?

    It’s a radar/communications mast, nothing more or less.

    Greece could show some interest in the Gepards since it allready has a few S148s and in the same time, it could even show some interest in the Bremens since the Kartenaers that she has are very similar. Depends of course on the status of the ships and any updates that may have taken place…

    German surplus equipment finds its way to NATO allies who’s military need a boost. In this case, Estonia, Latvia, Lithuania and possibly Poland would be likely takers of S148s and MCMVs.

    As for the Bremens, their commonality with Kortenaer/Elli is limited: F122 class has a different weapons and sensor fit, and also an entirely different powerplant. Then again, the powerplant of Bremen is similar to that of the Hydra class (Meko 200HN), so that shouldn’t be too much of a problem for the Hellenic navy.

    Everything I have read on ex-Varyag is that when she was sold to the Chinese, she was “without engines”.

    Now I know how sloppy & imprecise most journalists are, but maritime terminology uses “engines” for the mechanical propulsion devices (reciprocating engines, steam turbines, gas turbines, diesel engines, electric motors), and always refers to boilers separately from the engines!

    When speaking of both, the terms “propulsion plant” or “propulsion unit” is used, with “propulsion system” adding the propeller shafts & propellers as well.

    “Boiler” or “steam plant” are the terms used when speaking of just that part.

    Therefore, assuming the comments were an accurate relaying of what a naval source said, then the boilers were in place, and only the turbines were lacking.

    This makes sense, as boilers are large items that are usually installed during construction of the hull, before the decks above them are built. As Varyag was structurally complete, it would be expected that the boilers were indeed present.

    The turbines are also usually installed at the same time as the boilers, but they can be disassembled for a total rebuild (including replacement of all internal parts) well after the ship is completed, so I can see how they could have been left out with the intent of being installed later.

    Plus,

    any boiler, with a few exceptions based on unique designs, can be retubed

    http://www.holmanboiler.com/retubing.html

    Still, it is the boilers in the Russia plants that have been giving trouble (for reasons explained by Snake65). Note that the Kuznetsov has been retubed at least seven times during its years in commission! Not to mention the history of boiler room explosions or fires involving this plant, including on Gorshkov (1994), Novorossiysk (1995), Moskva’s (1973). How would the Chinese have tackled this known problem?

    The tailhook is controlled separately from the landing gear, so it is certain that the Su-33 has it lowered (where is it obscured from view by the engine & tailplane), while the J-15 has it stowed in flight position.

    That difference in the pics is irrelevant.

    Oh please. DO NOTE THE SMILEY.

    I’m aware that RDM is history, but I responded to

    And that is the current Walrus-class, probably among others

    And there I fully agree.
