    shoudn’t they use a steel model of the ship, painted with the same paint as the real Ticos? the difference in materials and the lack of paint would make a difference to RCS woudnt it?

    i thought the tips carried electronic warfare pods and the amramms was under the fuselage sides as on the old hornet? would the plane carry any other weapons other than two amraams and harm missiles? what about the nose cannon. would that go to make room for black boxes? 🙂

    the limited missile carriage isn’t a problem, since it can datalink target info to accompanying HARM-carrying hornets or F-16CJs…

    is it true that the bombs had to go through the hole made by the first one in order to destroy the reactor through all its containment/shielding? heard this from somewhere. sounds incredible for iron bombs…

    and that F-16s were chosen for the accuracy of their bombing computers?

    i don’t think the Growler has wingtip amraam stations – it carries a wideband signals receiver pod integral to the wingtip. but the fuselage side stations can still carry amraams of course.

    how would they test a full-size ship, say a DDX, at the RCS measurement range i wonder? would they have to build a drydock-size RCS range at the port?

    the keymags.co.uk link doesn’t work.

    but anyway, yes i’ve heard of the MACK before. i stand corrected.

    is page2 of the below final shape of the DDX ? pretty scary looking. I have seen a figure of 208m long (vs ~150m for the latest AAW ships) and a cost of $2.8b a pop during random searches.

    i don’t see any illuminator radars on the ship. i suppose DD(X) will use SPY-3?

    it seems individual, conventional illuminator radars like those on Aegis ships are on the way out, as they are very bad for stealth. the way to go seems to be 1) multifunction active arrays, like APAR and SPY-3, that can be blended into hull forms for low RCS, or 2) active homing SAMs like Aster.

    how are the russians doing this, then? they seem to be quite far behind the West in active array tech.

    looking forward to seeing EA-18Gs working together with F-16CJs.

    you notice every higher-altitude SAM needs a radar or some sort? that’s the problem. if your foe pops an ALARM over your head or is hanging around with HARM, when you switch on you risk saying bye bye to your SAM…

    its not a matter of having a good SAM, radar-based SAMs IMO are too vulnerable to today’s ARMs even if they’re mobile.

    otherwise i would go for the AMRAAM-based systems for mobility. the other truly mobile systems will find it hard to catch an F-15E at high altitude and high speed.

    here’s an aerial pic of changi east AB. got it from one of the singapore forums. it’s on the left, Changi International is on the right. for a military airfield it’s frightfully easy to eyeball from the air.

    the next time you fly to singapore, get a window seat on the right side of the airliner if it’s towards the end of the year, or on the left side if it’s the middle of the year. (this is due to the prevailing monsoon winds affecting the landing direction). chances are you’ll get a magnificent view as the plane descends into changi. i just came home yesterday from NZ and the cabin crew even told us to keep the window shades UP for the landing. got a good view.

    boy i hope i’m not a traitor by doing this 😎

    interestingly also, if SENIOR CITIZEN were really able to do everything it promises to, would it be a B-xx or a C-xx? we’ve yet to see a plane that was both a bomber and transport since, what, the B-18?? at the rate they’re going with the F/A-18 and F/A-22, SENIOR CITIZEN would become the A/K/M/B/C-xx. wow. talk about multirole!

    does killing an innocent airliner with hundreds of passengers make AEGIS battle tested?

    im sorry, i think AEGIS is an excellent system too, but i’m not sure it can be called “battle-tested” in the usual sense of the word.

    if you really wanted a stealthy tanker you could plug a big fuel tank and a retractable RAM-coated boom assembly into a B-2’s bombbay. control the boom from the cockpit via closed circuit cameras. if you wanted a stealthy transport for SOF insertion you could plug in a pressurised, airconditioned module with seats for, say, a platoon of commandos with a door at the bottom for them to parachute out of. hell, if you want a gunship there could even be a module with sensors and retractable guns and JCM/BAT/SFW or whatever ready to launch from inside.

    now this is of course still a longgg way from what SENIOR CITIZEN aims to be, B-2 doesn’t have STOL nor does it have the volume to carry many troops or any useful vehicles and it always needs a good airfield to land on. but you could have it soon, and i daresay, relatively cheaply- with B-2 development costs paid off i doubt new planes will cost more than $400-500million each.

    btw coach, an artists impression of SENIOR CITIZEN can be found in the link on pirate’s posting. BMACK is another designation for it.

    What I Still don’t understand completely is the differnce in capabilities.
    It seems the smaller ships cover with their SM-2 missiles (range ~70/80 Nm) a larger area than the larger ships with the Aster 30 (range ~50 Nm).

    In comparison: Daring/Sachsen

    Daring: 48 cells Aster 30/15 (Sylver launcher)

    Sachsen:32 cells SM2 IIIA or ESSM in Mk41 launchers + 2 RAM Mk 31 launchers (21 rockets)

    So got the Asters’s a better ECM resistance or why are they acknowledged as the more modern system ?

    the 70/80nm range u mention for SM-2 is for SM-2 block IV with the extra booster stage, which only the USN has. the european SM-2 ships have SM-2MR instead whose range is closer to 30/40nm. ESSM range is about 25nm.

    another good thing abt Aster is it has active terminal radar homing like an AMRAAM. it does not require separate illumination radars (eg APAR, Mk99 for the burkes and F100) which SM-2 and ESSM need. this allows virtually unlimited simultaneous engagements. whereas burkes with 3 illuminators can only handle up to 3 SM-2s/ESSMs in terminal homing stage. so advantages in this area are twofold:
    1)no illuminators needed
    2)no limits on number of missile/target engagements

    active radar homing also enables engaging low-flying missiles that are over the horizon of illuminator radars.

    in a sense Aster places the illumination radar in the missile rather than the ship, giving much more flexibility.

    a disadvantage however is the tiny active radars in the Asters are more prone to jamming than the much more powerful shipboard illuminators.

    PS: F100s have 2 illuminators.
