    Or is BAE systems hoping the RN will operate only its products?

    BAe has absorbed the VT shipbuilding division (VT exercised its rights to sell its share of BVT to BAe), this leaves BAe as the only company to operate warships construction yards in the UK.

    Apparently the Dutch are also facing problems with their CMS too, or rather, some of their equipment interfaces. This is separate from the problems they are having regarding the reliability of the APAR. These came from a Jane’s interview with the Provincien’s Weapon Engineering officer as recently as this May, so they are probably still facing this problem at this moment. SMART-L seems to be working very well though.

    The Nansans have Aegis, the first class of ships to be fitted with SPY-1F IIRC.

    With all that amphibious kit I can’t think of an occasion when they would ever let such an important asset as the CVF’s close enough to the shore to offload vehicles by Mexafloat anyway, so its probably for the best that they don’t have a dock.

    For what its worth (nothing), in my opinion they should have reroled Invincible as an LPH and put command facilities on Ocean rather then the Albions, giving Invincible and Ocean with the command and control facilities, and the two Albion class ships which will go closer to shore to offlload landing craft should have been the cheap ships since they would be in the more dangerous position during an amphibious assault.

    F100 –
    Length Overall 146.7m
    Length Waterline 133.2m
    Maximum Beam 18.6m
    Full Load Displacement 5,800t
    Full Load Draught 4.84m

    F124 –
    Length overall 143m
    Length waterline 132.15m
    Bean 17.44 main deck (16.68 beam DWL)

    I wouldn’t call that “much” larger. Very slightly larger. Full load displacement is given as about the same.

    Whether the F124 has room for more VLS cells, I don’t know, but if not, I think it would be due to the arrangement of the ship, rather than overall size.

    For comparison –
    De Zeven Provincien –
    Overall Length 144.24m
    Maximum Beam 18.80m
    Beam at Waterline 17.15m

    Hobarts are modified from the original F-100 to give a maximum full load displacement of up to 7,000t as a margin for later upgrades i believe. It might simply be a desire to get Aegis as i’m not sure if the F-124 has Aegis as such.

    Of course it could also be that the Meko-200 design used for the ANZAC’s was too small and because of later updates they are having topweight problems for future upgrades. They might just want to keep away from Meko, ANZAC replacements will be 7,000t destroyers.

    going off onto a diffrent subject but why did Australia go with the F100 over the German F124.. i dont blame them for not going American but the F124 seems like it would of been very competitive and it would probably have more commonality with the Anzacs

    The RAN wanted CEC capability which i’m not sure the Sachsen class has. In addition, the F-100 is a much larger ship with 48 Strike length Mk.41 VLS rather then 32 Mk.41 which again, i’m not sure if they are strike length.

    I also don’t know how APAR compares with the AN/SPY-1D(V) that Hobart will be getting.

    No offense, but the eurpopean air defense ships such as F100, Horizon and Sachen would more probably be labelled as Destroyers or Cruisers then as frigates.

    They are called Frigates for political reasons.

    Don’t tell me the Chinese (PRC) have purchased a decommissioned Essex Class, to which it is to be converted to a floating hotel/casino???:diablo:

    ROFLMAO. They already have 2 or 3 Kiev class carriers on top of Varyag don’t they?

    They might be small in comparison to USN CVN’s, but they are still over two football fields in length.

    Yeah Maybe it’s a firewall or something similar? The hangers on CVF are big enough for 40 aircraft and the space to maintain them.

    Are you sure the hangers are supposed to contain 40 aircraft? 😉

    I thought they were supposed to hold 24 F35’s.

    So essential an RFA Argus? Real shame it didn’t happen, she has her limitations but has been a real workhorse in the RN. Been used for transort, Medvac, LPH, Training….

    Right, like Argus they are are RO-RO’s, the difference being a rear superstructure and gas turbine (later diesel) propulsion.

    Those images are excellent. Assuming that hanger is based upon reality, its not very wide is it ? It doesn’t look much wider than an invincible class hanger. There must be a reason, as the layout of the hanger will be one of the areas where they will have focussed a great deal of design time.

    That image actually looks a bit strange…..Fairly sure there are pictures on navy matters showing the hanger of CVF as twice the width of the Invincible class hanger plus quite a bit longer.

    That has been delayed. And based on what was said when it was, I think that the cheaper alternatives being considered mean that a foreign yard might be used. I heard south Korea being thrown around. It would make for a cheaper ship for sure.

    South Korea was being thrown about for two reasons. They are a cheap foreign shipbuilder, and because it was reported that UK shipyards would not have the build capacity for MARS with current programs. If the shipyard capacity issue has changed, then MARS could be built in the UK where the government would get a lot of the cost back in tax.

    Lol and that replacement is years away yet. Ocean is only 19 years old. Compared to the Invincible class, it is barely out of nappies.

    Ocean commissioned in 1998 making her 11 years old. She was designed for an 18 year service life and has been worked hard. There have also been reports that due to her economy build, she is not exactly in the best material condition these days.

    Too true, even though they are in urgent need of replacement. The Tankers were supposed to be out by 2010 by law.

    Tankers are cheap compared to a full out warship and they keep many people busy “bashing metal”, whats not to like?

    1) Probably, they started building a Nimitz sized CVN in the 1980’s.

    2) Why are you asking? they don’t exist in service anymore so it is irrelevant.
    Probably not though, even before strengthening for catapult operations they weigh almost double the weight of the F8 crusaders that operated from the essex’s towards the end of their service lives.

    We already have rumours of 2 yards set to close once CVF is done because FSC won’t be able to sustain them all.

    There is always MARS to keep them busy. 😉

    Yes, yes they do. Once again I’m wrong:

    “Iron Monarch being the world’s first commercial vessel powered by an industrial gas turbine engine….Owing to mechanical breakdowns leading up to 1980, she was docked at Newcastle, New South Wales for major modifications. Primarily, metal fatigue from thermal recycling had reduced performance down to 16 knots from almost 23 knots maximum at initial sea trials. From 25 September 1980 she underwent satisfactory sea trials after conversion to simple cycle operation. she steamed at 17 knots , from 90 tonnes of waxy crude per day whilst horsepower was 17,500. Resumed normal services within the fleet until 9 March 1983 when she was laid up at Newcastle owing to economic downturn coupled with rising costs and reduced speed performance. Placed for sale on the market, she was later given a reprieve when BHP management decided upon re-engining her.”

    So much for Iron Monarch (she remains in service in 2009, although as above she now has diesels).

    Iron Duke was scrapped 1986 after suffering similar engineering issus as Iron Monarch.

    Sounds like after the re-engineing Monarch did 18 knots on 30 tonnes of fuel compared to 20.5 knots on 82 tonnes of fuel, that means that the Diesels are a hell of a lot more efficient with a 2.5 knot reduction in the sustained speed.

    But it as it sounds like Duke was out of the picture for a 1988 conversion since she was razor blades by then. TLW is a good story though, I highly recommend it. Wish there was more mention of the ADF though.
