    Just guessing…

    The incremental acquisition of F-35b allows an initial 50 for 36 operational (9 FAA, 27 RAF). This will be alongside 88x tranche 3 and 2x CVF.

    Later more F-35 might be required (our options are open) to expand to 72 operational (27 FAA, 45 RAF). The RAF might want their second tranche of F35 to be land based F35c (our options are open). I think that the two orders will add up to about 100 units.

    I would expect the Taranis style UCAV will employ the landing software to bring back onto a CVF deck unarrested. Reverse thrust, flaps and brakes should be enough.

    You could add pods under the hull to boost drive power and there is room for more MT30s…

    This is all about running a STORL (rolling landing) carrier as cheaply as possible within a tight build budget. That’s where the cutting edge is, on the budget.;)

    Reserve Fleet

    I think we should do this anyway. Hard times or no, deeper reserves offer greater flexibility.

    The RN’s short range SAM will be CAMM once it becomes available, according to MBDA its going to be quad packable, rumour has it the RN are only buying Aster 30s not 15s.

    I hope that we see Aster 45s soon too. Something able to knock out ballistic missiles.

    @Perfect General, where is it stated that C3 will be 1900-2100t?

    The source for me was R Beedall, but he is quoting Janes, quoting Commodore Steve Brunton

    http://frn.beedall.com/s2c2.htm

    On 30 January 2007, S2C2 team leader Commodore Steve Brunton presented an overview of early S2C2 outcomes to a Defence Manufacturers Association conference. According to Janes he told delegates that “S2C2 largely focuses on the relationship between the current Type 22 and Type 23 frigates and FSC but it has also developed linkages to other capabilities. Mine countermeasures [MCM], patrol vessels and surveys vessels all offer us opportunities”…

    …C3 is currently envisaged as a vessel of approximately 2,000 tonnes displacement with a range of 7,000 nm for constabulary and minor war vessel tasks. Cdr Brunton said “We see this vessel being used for maritime security and interdiction operations. It would also have a large mission bay aft, reconfigurable for special forces, MCM or a Lynx helicopter.

    C3 – think tug boat with a shotgun

    C3
    -C2 without: VLS, artisan, harpoon or torpedo tubes
    -possibly a surplus 4.5″ gun rather then a 155mm.
    -mine hunting sonar
    -Unmodified IEP system rather then the modified one on C1 and C2.
    -modified aft deck arrangement to allow reconfiguration of hanger and flight deck to operate remote mine hunting equipment.

    Minimum of 15 to be built initially as replacements for the River class when the lease runs out, as well as the remaining hunt class and HMS Roebuck. With the Sandown class and the other survey vessels either replaced by a second class of C3 when their time in service ends, or by a second build of the original C3 class.

    These are 1900t – 2100t vessels, don’t expect a 4.5″ gun. An 76mm is the most you could expect. Something like 30mm – 57mm is more likely. Just for shots across the bows. You might see a single 8 cell CAMM vls, but that is more likely for be a wartime UOR (fitted for, but not with). A decent radar will be needed for finding drug smugglers and pirates. I fully expect the mine counter measures to be UUVs and/or a couple of 15m boats. A rear boat/UUV deployment ramp under the helo deck might allow survey sonar to be dunked off the stern. The helo might be an optional extra depending on the current mission (patrol only). The small size pretty well rules out a hanger. I’d be surprised by orders for more than ten of these.

    Eurojet is confident that its engine will be chosen by the ADA, it will have to beat the challenge from GE, which had made a preliminary presentation on the GE414.

    Sources in the ADA said that while the EJ200, with a thrust of 90 kN, brings in the latest technology in combat aircraft engines and is lighter and smaller, the heavier GE414 is capable of producing more thrust (97.5 kN). But Eurojet officials said the EJ200, which is the only five-stage compression engine in the world today, has the potential to meet the Air Force’s requirement of 100 kN.

    The workshop was also an indication that the ADA has accepted the Air Force’s contention that the Tejas in its present configuration is unacceptable.

    This article from The Hindu suggests that the 72kN(103kN reheat) EJ230 is alive and well. Can we expect EJ270 in time for the Typhoon mid life refits?

    The last Russian leader to go toe to toe with the US was 2-3 leaders ago. Putin maybe old school middle management, but he doesn’t know what he is inviting. Russia should stick to picking on countries more it’s own size, like the UK.

    For that matter the AGI sight actually shows the replacement for DAPS:

    http://www.agiltd.co.uk/visual_landing_aids/glis/

    An angled landing deck with arrester wires and a ski jump ramp for take offs (SToBAR) offers:

    1. safer/longer landing for a high bring back rolling landing
    2. option of E2d Hawkeye with strengthened nosegear for better AEW
    3. outside chance of Sea Typhoon for CAP
    4. option of F35c and F-35b operating together
    5. easier/cheaper adapting to cat and trap if needed later

    Two MT30 and two diesels (one 4MW for hotel and loiter plus one 8MW for cruise – about 21+ knots) should be more than enough power for a fast destroyer that can keep up with nuclear submarines. While the pods don’t need to be azimuthal, they still bring a more efficient hull shape to the show than water jets alone. Four next generation electric motors could be 2x 20MW pods plus another 2x 20MW and whatever the steam turbine supplies for the water jets. Even 8000t powered by that is going to shift up to 35 knots. Unless you design for high speed you won’t get the most out of the water jets. Even a range of GTs are going to be less efficient than diesels for routine power.

    Two buckets.

    This is a great idea! Has it gone any farther? Decision on scale or guidelines?

    I would recommend two photobucket main folders on the site. One for large aircraft (1 pix = 0.05m/2 inch) and one for smaller aircraft (1 pix = 0.025m/1 inch). The inch values are not exact so it would be best to use them as a guide and stick to metric for the standard. Side, front and top views would be standard, underside and/or back views would be for extra credit/detail.

    The main folders should be split into Never-were/Experimental/Prototype (prop and jet sub folders), pre and WW1, Interbellum, WW2, postwar props, early-1965 jets, 1966-1990 jets, Modern aircraft (Civil and Military subfolders).

    I would recommend blank papers (a4 and a3) with the scale already marked available to download onto Paint.

    What sort of range can we expect from a Tranche 3 Typhoon with CFT and underwing/centreline tanks? The weight of fuel will affect maximum super cruise speed, but will the extra drag/shape of the conformal fuel tanks?

    EdLaw,

    Another possibility: immediately accept Georgia and Ukraine into NATO, and station a small squadron of NATO aircraft in Georgia, a la Baltic air policing mission. A modest number of aircraft would then be more than enough, since Russia would really have to think twice (or more) about shooting at NATO aircraft. Georgia would then focus on ground-based stuff, i.e. SAMs, better troop training, new equipment etc… By removing arguably the most expensive part of the re-equipping phase, i.e. fighters, they can focus on more achievable goals. If they want a boost, pick up a few hundred ex-stock M60 tanks, upgraded to Sabra spec; several hundred M113s, and so on.

    Forget small squadron. Think major airbase and SAM system. Put in one of those ABM radar stations (like in Poland – that the Russians love so much) up Mt Kazbegi. This is grounds for placing Georgia within the NATO structure (on condition that they don’t kick off without NATO-wide agreement). This would be a check on both sides. I too think that this should be acted on now. Would Gori or maybe Tskhinvali be a good place for a base?

    Stop!

    What kind of committee tries to design the ship themselves?

    I expected this to go out to tender based on a loose spec and design requirements in terms of capability.

    • I like the aft boat launch combining with towed array deployment tethered either side of the ramp.
    • I’d want two 14m rigid boats able to clear mines between them. Above that a helo deck big enough to take a Merlin or even Chinook.
    • Further forward two Merlin service/arming hangers above the storage deck for the 14m boats.
    • Twin full azimuth pods plus twin screws driven by electric motors, powered from 3xWR21 or 2xMT30 plus cruise diesels below cooled funnel.
    • Sampson radar mast (like on Type 45).
    • Radars and Sonars to maximise use of weapons systems from existing models
    • CEC
    • Launcher (48 cells – room for 96) capable of supporting Land attack missiles, ABM missiles, med-long range anti-air missiles and quad packed short range anti-air missiles.
    • 155mm Gun compatible with army 155mm self propelled and/or 155mm light artillery.
    • Support for a crew size of 200.
    • Reduced signature to at least the levels of type 45 (radar) and type 23 (sonar).
    • Range and speed to match or exceed CVF in all sea states.

    It is expected that this can be implemented in an off the shelf type 45 hull design modified to meet the spec within the same volume.

    After an initial order for one, first of class, 2-3 follow up 3/4 ship batch orders depend on meeting deadlines and agreement on costs. Although there is a requirement for at least six ships and perhaps as many as 12, initial order only ensures the first of class will be built. Further contracts are negotiable.
