    I guess invading France has never been easier, just a few hundred tickets on the Eurostar and we can be dining in Paris by this evening! I wonder if the Germans can be convinced to join us? ;):D

    President Sarkozy of France officially announced a couple of hours ago he is running for reelection … France Forte 🙂

    but is that really a useful feature of the ship or the helicopter?
    meaning, a Cavour or Kiev could carry the same helicopters?

    http://digilander.libero.it/en_mezzi_militari/html/garibaldi/sezione551b.jpg

    Nominal 16 Harriers or 18 SH-3D Sea Kings but a mix of 13 helicoppters plus 10Harriers is possible. Not bad for a ship with 10,000 t standard and 13,850 t fulload displacement.

    Kiev: 12 or 13 Yak-38 Forger VSTOL and 14 to 17 Ka-25 Hormone or Ka-27/29 Helix. Some more helicopters and STOVL jets and way heavier, offensive armement. 36,000 standard, 43,500 full load.

    Moskva: 14 Ka-25 Hormone helicopters, with heavier armament on 11,200 tons standard to 19,200 tons full load.

    I saw in last months “Air Forces Monthly” that the Italians have removed the Otomats from the Garibaldi in order to expand the flight deck.

    How much larger are the EH-101 compared to Sea King and how much larger J-35B compared to AV-8B plus Harrier? Maybe they need more space with new aircraft.

    But looking at the pic below, it seems not much deck area expansion (new dome)

    The Kiev class – and also the Invincible class – was designed for hunting submarines. The aircraft should have been used only for defence.

    The big carriers of the USN are designed as attack carriers and their aircraft are the primary offensive weapon – comparing apples and oranges.

    The Russian and British ships were converted, because they were later used for different purposes than designed, because the main tasks of their navies switched from antisubmarine warfare to power projection – and therefore the aircraft were needed as offensive weapon system.

    Agree, also ‘explains’ Kuz & Varyag

    The ‘switch’ to the MiG-29K has nothing to do with it being a smaller aircraft.

    In fact, as I have pointed out over and over again, the Su-33 actually has a smaller deck footprint than the MiG-29K.

    Way back, Sukhoi proved that it would take 50 MiG-29K’s to do the job of 30 Su-33’s – one of the reasons that the latter was chosen.

    The latest Russian Navy MiG-29K is simply a new airframe with improved radar and avionics procured on the back of the Indian Navy purchase/R&D.

    Had the Su-33 been given the same funding & upgrades as the MiG-29K, it would, no doubt, still be the preferred option.

    But then I am slightly biased……. :rolleyes:

    Ken

    I’m not talking about the foot print (wether ‘folded’ or launch ready). And I’m not looking at relative effectiveness. There will be more Mig29 than Su33 boarded. And more aircraft means more space is needed for support, be it personnel, ordnance, maintenance/repair, etc.

    They’re in positions that do not affect the flight deck.

    Not having Aspide launcher with associated automatic reloading systems in superstructure below the launcers would free deck space at the front and rear of the flight deck.

    Not having Otomat launchers on the port and starboard side of the stern would allow for expansion of the flight deck area.

    This has been tried in various degrees 3 times in the last 30 years. The Invincible class, which ended up having its Sea Dart launcher removed for additional aircraft capability. The Kiev class of which 3 were scrapped and the last one is being rebuilt to a STOBAR carrier with no missiles, and the Kuznetsov which is having its flight deck mounted anti-ship missiles removed for extra aviation facilites. Anyone notice a pattern here? The escort/carrier hybrid usually ends up as a ship that’s pretty terrible at both.

    However, I don’t recall the Italians removing Otomat AShM, Aspide SAMs, Dardo’s, or triple asw tubes from the Garibaldi to make room for more AC.

    The scrapping of the Kievs is more a result of CCCP collapse than a reflection on the design. The Indian Navy needed a carrier replacement, which could fly something other than Harrier – which would eventually phase out with at that time no guarantee of a suitable VSTOL jet replacement coming available, hence the need for a flight deck modification on the Gorshkov.

    With the Kuz, noticed the planned switch to Mig29K, a smaller AC? They want more wings on board, which means also more support. What modern replacement would there be for the installed AShM? Would it need to be smack in the center of the flight deck?

    It also could be a Lakshya PTA or Mirach .it was the target of Barak interception.

    The ship in that pic is a Khukri class corvette. It has 4 x P-20M missiles. It has no Barak launchers, just 2 x SA-N-5 SAM (MANPADS) launchers.
    http://en.wikipedia.org/wiki/Khukri_class_corvette

    I doubt Lakshya PTA can be launched from such a corvette in this direction (maybe from the helideck in the rear, but then it wouldn’t be fired forward). Likewise Mirach.

    Take another look at my post, and you’ll find this:

    Perhaps the other older ships to be retained have already had the hull repairs and the newer ones have not?

    CG modernization begins in FY 2006. The first ship scheduled to undergo modernization is USS Cape St. George (CG 71). The remaining 21 baseline 2, 3 and 4 cruisers have varying capabilities. The cruiser conversion program will result in all 22 ships having a common warfighting baseline. Improvements include quality of life initiatives, better weapon systems, SmartShip upgrades, remote monitoring capabilities, force protection upgrades, optimal manning, open architecture, and many other improvements.

    – The most recent challenge is the discovery of sensitized aluminum alloy in areas of the superstructure, and how that complicates modernization of these vessels.

    A little newer… October 2011

    Twelve ships face axe in US budget cuts

    The US Navy is planning to retire nine Ticonderoga-class cruisers and three Whidbey Island-class dock landing ships (LSDs) in Fiscal Years 2013 (FY13) and 2014 as austerity measures hit the Department of Defense (DoD).

    The cruisers slated for decommissioning in FY13 are USS Normandy (CG 60), USS Anzio (CG 68), USS Vicksburg (CG 69) and USS Cape St George (CG 71), with USS Princeton (CG 59), USS Cowpens (CG 63), USS Gettysburg (CG 64), USS Chosin (CG 65) and USS Hue City (CG 66) following in FY14. The nine combatants entered service between 1989 and 1993.

    The amphibious platforms scheduled for decommissioning were identified as USS Whidbey Island (LSD 41), USS Fort McHenry (LSD 43) and USS Tortuga (LSD 46). The trio entered service between 1985 and 1990.

    Baseline 3
    USS Princeton (CG 59)
    USS Normandy (CG 60)
    USS Cowpens (CG 63)
    USS Gettysburg (CG 64)

    Baseline 4
    USS Chosin (CG 65)
    USS Hue City (CG 66)
    USS Anzio (CG 68)
    USS Vicksburg (CG 69)
    USS Cape St George (CG 71)

    Odd, they all seem to be newer ships… leaving older baseline-2 ships CG 54-58 and some baseline-3 ships (cg 61-62) in service along with baseline 4 ships (cg-67, 70-73)

    Interesting you left out this bit from the second article

    The U.S. fleet keeps its 11 aircraft carriers as well as its 10 air wings. About a third of the fleet of 22 cruisers — seven ships — will be decommissioned early

    That’s 2 less to be cut…

    And, the specific ships may not yet be clear

    Due to a Congressional requirement, stated in the Budget Control Act of 2011, to cut the Defense Budget for FY2013 and subsequent years, plans are being formulated to decommission seven of of the 22 in the cruiser class.[6] The retirements will begin in FY2013 and continue through early FY2015. Ships mentioned to be decommissioned include Vicksburg, Chancellorsville, and Leyte Gulf, as they have yet to receive the BMD radar and SM-3 upgrades of the other ships in the class.[

    http://en.wikipedia.org/wiki/Ticonderoga_class_cruiser

    Two (CG55, CG62) of three ships mentioned don’t appear in the previous list…

    WOnder if this is the real reason…

    an issue that is plaguing all 22 cruisers in service: cracks in the aluminum superstructure

    The problem, according to the Naval Sea Systems Command, is the aluminum alloy used in the superstructure of the cruisers, which have steel hulls

    “There have been various degrees of crack repair on every CG [guided-missile cruiser] in the past year,” said Chris Johnson, a NAVSEA spokesman in Washington. “The decking is the most prevalent cracking area due to exposure to elevated temperatures caused by solar absorption and exhaust temperatures.”

    More than 3,000 cracks have been found so far across the entire Ticonderoga class,

    http://www.navytimes.com/news/2010/12/navy-cracks-plague-ticonderoga-class-cruisers-120910w/

    Are there any likely foreign takers for USS Whidbey Island (LSD 41), USS Fort McHenry (LSD 43) and USS Tortuga (LSD 46)? E.g. India (though to be looking to built 4 LPD at home, yard may be full/slow).

    Um… that report is half a year old, and is well out of date.

    So, you got anything newer on those Perry’s then?

    US Navy will be decommissioned 3 frigates Oliver Hazard Perry class – Boone, Stephen W. Groves and John L. Hall, Amphibious transport dock -Austin class- Ponce.

    3 frigates, amphib to leave fleet in 2012

    IIRC one will serve as spare parts hull but the others may be transferred. Wonder who’ll be the next taker: PN or ROCN.

    The prototype MiG-29K (side number 311) was loaded by crane onto India’s new aircraft carrier in Severodvinsk last month.

    The Sevmash Dockyard said that work to convert the former Russian cruiser Gorshkov is 90 percent complete.

    I think that happened in November 2011…

    The prototype MiG-29K (side number 311) was loaded by crane onto India’s new aircraft carrier in Severodvinsk last month.

    The MiG-35D demonstrator (side number 154) has been fitted with an arrestor hook and will take part in the sea trials of the Vikramaditya. It replaces two-seat MiG-29KUB side number 951, which crashed at Akhtubinsk earlier this year. Single-seat MiG-29K side number 941 will also fly in the trials, rather than the prototype aircraft now onboard. (It is one of two MiG-29Ks that flew trials on Russia’s only aircraft carrier, the Admiral Kutnetsov. Later, both aircraft served as demonstrators and testbeds in various MiG programs before being grounded earlier this year.)
