    I don’t see why we are discussing Typhoons. The fact that the new Government has opted to confirm the Super Hornet buy means we are committed to the JSF in the long term. If that was not the case then there would be no need to purchase an interim aircraft as all the JSF alternatives are available right now.

    1) Improved legacy aircraft ie F-16 Block 80 etc, F-15XX etc. Available right now.

    2) Eurocanards. Available now.

    3) F-22. Well not actually “available” but if you don’t get em now then you won’t be getting them at all.

    The new Government has accepted we are committed to the JSF, its just a matter of how they spin it to avoid admitting the previous government did anything right 🙂

    New Launcher Completes Final Design Review

    (Source: US Naval Air Systems Command; issued Nov. 28, 2007)

    NAVAL AIR SYSTEMS COMMAND –– Patuxent River, Md. – The Electromagnetic Aircraft Launch System recently held its final critical design review (CDR) at the prime contractor’s facility located in Rancho Bernardo, Calif.

    The review team, led by Mr. Dave Cohen of NAVAIR’s Systems Engineering competency was presented a wealth of data by the EMALS prime contractor, General Atomics.

    The team spent a week thoroughly reviewing the entire EMALS program and determined that the design is technically compliant with requirements and is properly documented.

    Although a few open action items remain, Capt. Stephen Rorke, Aircraft Launch & Recovery Equipment program manager thought the review “was a rousing success” and praised the team for their “dedicated efforts to complete preparations for this review” even as the San Diego fires closed the General Atomics facility for a few days in the weeks just prior to the CDR.

    Capt Rorke also thanked the team for open and honest dialog during the months leading up to the CDR as evidenced by the fact “the team knew about all open issues prior to the review and that no issues of major significance surfaced during the CDR.”

    EMALS, a new electromagnetic aircraft launch system for the next-generation aircraft carrier, the Gerald R. Ford class (CVN-78), will replace the current generation of steam catapults used on the Nimitz class aircraft carriers.

    This switch to an electrical based system versus steam, will lower operating costs, require fewer people to operate, improve catapult performance and expand the range of manned and unmanned aircraft that the aircraft carrier can launch.

    The next step in the process is to begin installing the full size, ship representative EMALS equipment in the recently completed EMALS test facilities at Naval Engineering Station Lakehurst, NJ.

    The EMALS equipment installation is scheduled to begin in mid 2008, with actual testing to begin in early 2009. Testing will continue throughout 2009.

    The first components of the EMALS equipment is scheduled to be delivered to Northrop-Grumman Newport News Shipbuilding, Norfolk, Va. to be installed in the Gerald R. Ford (CVN-78) in 2011.

    The Gerald R. Ford is scheduled to be delivered to the US Navy in 2015.

    MConrads: Mate any chance of you providing us with one of your spectacular drawings of an Anzac with the CEAFAR and CEAMount systems and the Mk-8 Quad pack Harpoons, don’t forget the Nulka decoy system and Seahawk aft. Thanks in advance mate.

    Secondly for everyone: That pic I provided of the Sea Zenith system, has anyone else noted the Missile kills on the side of it? Is anyone able to shed any light on this and why there are two types of kill markings, I mean with a CIWS it’s either a kill or the ship is sunk right? No assists in this threat zone is there.

    Well that might be the case in a war situation but since these markings will only be from exercise shots a partial kill is possible. BTW Harpoons quad packs are Mk-141. Only Mk.8 I can think of is the UK 4.5″ gun mount. BTW2 just as the AK 7.62mm round does not equal the NATO 7.62 (7.62×39 v 7.62×54) nieht do the Sea Zenith and Bushmaster employ the same round (25×184 v 25×137).

    So the supersonic capability of the Kh-31A wouldn’t make it any more effective against an AEGIS protected vessel? I was just trying to gauge how effective this AshM is compared to Exocet, Harpoon etc…especially since China uses it…(Venezuela and Libya should be getting it soon with their Su-30s)

    While the speed would be useful in the event the attacker gets the missile away the point about the launch envelope is that the attacking aircraft would have come well within the engagement envelope of the target AEGIS vessel. If you kill the launcher who cares what it had under its wings.

    While many say the F-100’s are the equal of typical Aegis Destroyers like the Burke and Kongo Classes except for fewer missiles. Doesn’t the F-100 use the SPY-1F in place of the larger and supposedly more capable SPY-1D. Further, while the current releases from Australia claim the SPY-1F can be upgraded to fire SM-3’s. I have read several sources that state otherwise????:confused: :confused: :confused:

    F-100 uses SPY-1D but IIRC it may incorporate some of the lightenend components of the SPY-1F. The -1F is on the Norweigen Nansen’s which are also built by Navantia

    As with the ANZAC class Vs Adelaide class Forum

    I have always thought that Australia could have stretched the Oliver Hazard Perry Class FFG design that little bit further as a follow on to the first two OHP batches.
    I had always thought of lengthening the design by adding a plug at the bow to take a 32 or 48 cell Mk41 VLS in place of the Mk13 single arm launcher and magazine.
    This would hold VL Standard MR.’s and ESSM’s.
    I would also have replaced the single shaft arrangement with a twin shaft arrangement.
    Then just recently I discovered the Taiwanese the ‘Tien Tan 1’ Guided Missile frigate (FFG) project

    Did Taiwan end up building the ‘Tien Tan 1’ Guided Missile frigate (FFG)
    This was to have been a far more capable and lengthened variant of the US Oliver Hazard Perry Class FFG.
    I am after information on this design and program – specifications, drawings and (photos if any)

    Regards
    Pioneer

    One of the biggest problems with the OHaP design is stress cracking of the superstructure. Lengthening the design would only exacerbate this. Incidently this problem also makes the design marginal for RAN patrols in the Southern Ocean.

    SEASPRITE HELICOPTERS

    In April 2006, I initiated a full examination of the Seasprite project following grounding of the aircraft due to concerns over the reliability of the Seasprite’s Automated Flight Control System.

    The review paid particular attention to the reliability of the Flight Control System and its associated safety implications; the ramifications to Naval aviation of the project being 6 years late; and the performance of the integrated sensor system.

    The review examined how to resolve these issues so that the best possible capability can be provided to the Royal Australian Navy.

    After detailed consideration of the issues involved, the Government has decided to continue the Seasprite project, subject to satisfactory contract arrangements.

    The return to flying will involve a series of controlled steps to assess the contractor’s performance, and to ensure the safety, performance and reliability of the Seasprite.

    The Government will take steps to ensure that the contractor’s progress is measured against milestones during the course of the additional work.

    How and why are they getting them through Syria?? Russia had no problem selling Tor-M1 air defense systems directly to Iran so I am sure Russia would have no problem selling the Pantsyr sytem directly to Iran.

    Bit of a kickback for Hezbollah’s help keeping Lebanon destabilised.

    There were a few pics posted around at the time of the incident.

    http://content.answers.com/main/content/wp/en/7/79/Idf-saar5-hit3.jpg

    In the above pic, you can clearly see the damage just below the aft of the hanger at the waterline. Had the missile had a bigger charge or more missiles used in the attack, I doubt Hanit would be afloat today and I doubt Hezbolah would be around as a group following that.

    This is what happens when you under estimate an Enemies capabilities. Israel thought that the navy would never be attacked because they are off shore. I can tell you now that they’ll never make that mistake again. As a result, the IDF/N have increased spending to cover more training and expansion of the fleet.

    That picture shows the diesel exhaust. The same shots were circulated at the time of the attack and the assumption of damage corrected then. Short memories. As Wanshan indicated there have been practically no photo’s of the damaged ship. According to the IDF the reason the ships defence’s were stood down were a) the situation for the offshore was considered to be pretty benign but also b) they did not wish to interfere with the IDF/AF aircraft in the area and their EW equipment etc. Maybe thats a valid reason maybe its not but thats pretty much all we know.

    To explain you how the Kolchuga works is very easy, imaging the Kolchuga is an eye and the APG-77 a lamp, the lamp (APG-77) changes the color of the light it emmits every five seconds, it goes from red to white, white to blue and so on all the colors of the rainbow even moving the lamp you will be able to see the lamp

    Now imaging the F-22 is a mirror, if you face it in a 90 degrees angle you can see your face, if you incline it to 40 degrees or 150 degrees you wont be able to see your image well some parts of the image will be areased or difficult to see however while you have several persons at different angles with respect the mirror you can have a better image of the object and you can compare what every body saw. that is the way the Kolchuga works the difference it does not work with light but other frequencies of the electromagnetic spectrum;)

    The light and eye analogy is often used to explain active and passive systems and it is quite effective. However its just a simple illustration. To paint a picture of the task the Kolchuga would in countering a wartime strike by F-22 type aircraft the F-22 is actually a single star against the background of an entire galaxy of stars and the problem you face in trying to localise it is that it is moving and as you say it is constantly changing colour. Against the confused background therefore it becomes much harder to localise with any certainty.

    Very interesting. That Fairy concept certainly looks the most practical design. reminds me of a Backfire actually. The Vickers/Supermarine one is definitely interesting but would a quite limited design I expect. Then again planes back then weren’t expected to serve for thirty years.

    Good point about the SDB’s.

    Another ‘lack of’ that I have just though of is the lack of any penetrator munitions for hitting hardened targets such as missile silos.

    I’m pretty certain this is the big sticking point for the RAAF on the F-22. Sure it can carry 8 SDBs but if you are carrying out a bug swatting strike then there is a good chance that the target will be in a bunker, bad guys all seem to learn to dig really quick. F-35 can carry standard 2000lb penetrators F-22 cannot.

    Its a newspaper report in a South Korean paper. I’ll believe it when I see it. This report has been around on other boards for about week now and the amount of scepticism is only outweighed by the fanboys prostrating themselves in worship.

    Dan: mate the MH-47 fits on the LHD’s no problem (especially the spanish version). I saw a model of the Thales proposal (Mistral) at the show and they quoted the MH-47 as being operational from the aft lift, which was specified in the original requirment for these ships. I’ve previously seen the other ship on offer, the model form anyway, and it had a model of a CH-47 on the back of it as well.

    Interesting. Still it can’t be ideal given the lack of folding blades a Chook displace at least a couple of other craft from the hangar.

    As for flying out of Butterworth, mate we handed that base back to the Malaysians when we retired the Mirage III’s, sure we still fly up there every now and then but it’s not our base any more. Info on Butterworth.

    Huh! I was actually in Malaysia 81-83 as my father was posted to Butterworth. Obviously I wasn’t aware the base had been formally handed back to the Malaysians. Just assumed since we still aircraft and personnel there on a permanent basis. I almost went back myself in 1999 (IIRC) as part of the Rifle Company. 6RAR at Enogerra was tagged to provide the next rotation and they need to fill out the company so other units were invited to provide volunteers. I was a reservist with 2CER at the time but missed out on the trip. I ended up getting married later that year so it was probably a good thing 🙂
