    don’t forget that the brits, french, spanish, germans, italians, dutch, aussies, americans and singaporeans are continuing to invest heavily in their SSN/K fleets! after all, the best defense against a submarine is another submarine.

    there is also a general trend of improving ASW helicopter fleets.

    it’s not like the Cold War times when the soviets would flood the atlantic with hordes of foxtrots charlies victors and oscars and NATO needed big ASW surface fleets to counter that.

    i think U-2 is getting rather long in the tooth and ought to make way and free up cash for alternative reconnaissance platforms.

    what can U-2 do that SBIRS and SBR can’t? try realtime blanket IIR/SAR coverage of an entire theatre?

    if i were an infantryman facing down a tank and all i had was a Mistral i would desperately shoot it at the tank and be happy that it got “neutralized” and i am still alive. however if anything else was available like Eryx or Predator or Javelin or Spike i would of course use those first. and save the mistral for enemy helicopters.

    generally speaking the lines between anti-tank/aircraft/ship missiles are kinda blurred. Hellfire can be used quite effectively against helicopters, AIM-4 Falcons were used against ground targets in vietnam, and USN doctrine envisages long-range HARM shots at radar-emitting enemy ships.

    i’ve always wondered – what is the difference between AGM-114L Longbow Hellfire and Brimstone? in terms of their MMW seekers, and modes of operation.

    it’s clear that AGM-114L’s seeker is less capable that Brimstone’s, but how exactly is “less capable”?

    do these missiles work with active homing with their internal MMW radars, like AIM-120? looking for a radar image that looks like a tank, and then homing in on it?

    or does AGM-114L use a SARH system where it relies on the Longbow radar for guidance and therefore can only be used from Longbow attack choppers? whereas Brimstone can be used from most platforms.

    1. the fact that the originator of that article would not identify himself casts some serious doubt on its credibility.

    2. if this deal was really going through we’d have heard more of it from official sources by now. in any case i don’t think an upgrade to Block60s figures in the RSAF’s plans; the F-16D52s are meant to do deep strike/interdiction and for that APG-68v9 with SAR and LITENING II will do very fine. the F-15SGs already provide the same airborne AESA and IRSTs that Block60s will bring will additional heavy-weapons lifting capabilities.

    what are the F-15SGs for if we are going to get block 60s?

    thanks for the links, they look great, but sadly very few of us here can read japanese 🙁

    I disagree that the use of SDB will render those weapons useless. They were not aimed at fighting a war such as those which western countries engage at present (ie Yougoslavia, Iraq or Afghanistan), but it was designed for another type of mission set in a much more dense war environment. I don’t see how they could be replaced by SDB if a major conflict ever broke out.

    Then the US probably would be able to hit important and very well defended targets thanks to their stealth AC/and missiles combo… for european nations it would be more difficult, and those type of missles would definately be required. Of course their price would render them reserved to high priority targets, but I’m sure there would be plenty of those to chose from if the hit was to ever hit the fan.

    1. agreed – an SDB-only force would surely be inadequate.

    USAF A2G doctrine for the next decade or so would involve JASSM and JSOW launched from long range to take out heavily defended radars, SAM sites, C3I installations etc. even to close to 60 miles (SDB range) with F-22/35 would place the aircraft in danger, especially given the capabilities of S-300 level opposition. once the big radars and SAMs are taken out you could mass-plink enemies with masses of SDBs.

    in any case SDB lacks the warhead weight to take out larger/well-protected targets.

    2. i think the JASSM vs SCALP/TAURUS debate is quite a simple one. JASSM offers less capability (shorter range, smaller warhead) for much lower cost and reduced RCS and size/drag.

    i emphasise the much lower cost; you could buy 2 or 3 JASSMs for one SCALP-EG. SDB is very cheap too. american emphasis on cheap weapons in recent years is a very good choice IMO, given their large scale of operations.

    ESSM is solid propellant just like AMRAAM. and a lofted profile alone is still inferior to the missile being ramjet powered all the way. but i do agree an ESSM with an AMRAAM seeker would on these arguments be superior to AMRAAM itself.

    JDRAAM is the still-on-paper AMRAAM replacement. i think it stands for “Joint Ducted Ramjet AAM”. see the other thread on BEST DOGFIGHT MISSILE.

    Something people don’t always consider. There was an A-10 during Desert Storm that had guy-on-a-bike sillouette painted on the side as one of it’s “kills”. The caption read something to the effect of “airforce accountants would not be pleased if that cost a Maverick”.

    you can’t lock on a Maverick onto a motorcyclist. TV and IIR guidance wont have the sensitivity to track and i don’t think they got a grunt to point a laser at that cyclist. probably a GAU-8 frag. not such a great waste there lol :diablo:

    The thing is ESSM is almost double the weight of an AMRAAM however the lengths are pretty close to the same so it should even fit into the internal bays of the F-22. Where the air launched AIM-7 has about three times the range of the land-launched version if you applied the same to ESSM that should give you about 85 miles of range from the air. It’s even got vectored thrust during the boost phase (has a integral boost/sustain grain) so in theory you could probably use it in very close too if you’d swapped out it’s SAR seeker for say the AIM-120’s seeker.

    my main issue with this idea is that the heavy ESSM when deployed as a long range AAM (Phoenix replacement) would have an inferior NEZ to the likes of AMRAAM, JDRAAM and Meteor. solid rocket-powered missiles (even with boost/sustain) are on the way out because they bleed energy very fast when they have to make turns to intercept a maneuvering target, especially during terminal homing.

    even boost/sustain motors stop burning within seconds of launch, and the missile essentially glides the rest of the way. thrust vectoring to increase maneuvrability in terminal homing (at long range) would be useless simply becacause the ESSM would not be exhausting anymore.

    this greatly reduces NEZ, especially against todays supermaneuvrable fighters. thats why ramjet power is coming in because the missile is powered all the way, reducing energy bleed. hence JDRAAM, Meteor and R-77PD.

    Is it me, or does the island look dangerously far back, i.e. very close to the landing path?

    It is interesting that they claim ‘cost savings’ as a reason for the new design – the ships are predicted as ~$3-4bn more than a new Nimitz class, all to save a predicted $5bn over the 50 year life of the carrier…

    the $3-4bn extra for CVN-78 factors in the R&D and new-technology costs for all the new inventions – EMCAT, electric drive, increased intraship networking etc. should be able to spread out the cost as more new carriers are built. a

    and the $5bn savings is just the money – think of all the benefits the new tech brings. increased launch weights and better safety from the EMCATs and new arrestor schemes, more flexible power management from the electric drive etc.
