    i’d say the latter link (article) is talking about audio messages, or radio communication if you will. It doesn’t mention filtered and edited info on the situational awareness which is then fed to the other planes through digital datalinks.

    The first article mentiones, as is pretty much public knowledge, that there are plans for implementing proper network capability to the raptors in the not too distant future.

    considering the range figures sm-3, given its volume, offers, i’d wager the 600 km figure will be attained mostly through further refinement of guidance/steering methods and, consequently, the flight profile.

    Village idi, can you describe the tactical situation better to me? What mission does the emcon silent carrier group have? What sort of maritime enviroment are we in? Near an ocean coast, in a large sea, etc?

    In a nutshell, though, one needs a larger and stronger force than the enemy has to counter a carrier group that wants to attack a coastal target (or one beyond the coast).
    Though, it may be more cost effective not to go after the carrier group at all but just try to deal with its airplanes, and to an extent, cruise missiles.

    The Tomahawk, like any other proper cruise missile, is NOT a replacement for precise bombing. Tomahaws are meant to help breach a door through the enemy’s defenses, or, alternatively, cause (in some situations limited) damage to strategic targets behind enemy lines. On their own, a salvo of tomahaws aren’t that useful, when their price tag and available numbers are taken into consideration. To take full advantage of their ability during an attack on the enemy defenses one simply has to follow on with proper air strikes with airplanes and bombs – in much, much greater numbers than what current cruise missile inventories of any country can offer.

    Did/ does mig-31 cruise over mach 1 without ab? if so, at which speed? There are some figures out on the web for its range at 2.35 mach, and they’re way too big for an afterburner cruise.

    It’s very hard to come by any concrete info on this topic. Though, using mostly tidbits from the guide to naval weapons and various meterological radar articles, it would seem small-form oth radars are using some sort of ducts that USUALLY appear over water, if weather conditions are right. Like 80% of the time. But it’s not a sure thing. I still have no real info on wavelength as a function of range. Band stand radars (mineral) seem to be an example of a radar i’m talking about here. Or italian kondo-r radar.

    SOC, got any more info? 😀

    Is it just me or the vertical tail surfaces on that image seem to be one-piece, all moving surfaces?

    Right now there is no such operational capability but it is in the testing. AMSTE program (google it) has been trialed with fair level of success for both engaging moving vehicles and moving ships with modified jdams being continuously redirected via datalink. Perhaps within the next 5-10 years what you’ve described will become the norm.

    For what it’s worth, Sparrow missiles fired in Desert storm had some 28% effectivess, Sidewinders had, in the same same conflict, 13% effectivess. Amraam, over its service lifespan, had 77% effectiveness. Context of those figures is unknown.

    jsow can be fired from internal weapons bay on f-35, but not jassm. F-22 can’t hold any of those in its bay. Both planes can carry 8 SDBs. And the earth revolves around the sun. 🙂 Version “A” of jsow has been in service for some time, and has indeed been used in combat. http://www.raytheon.com/capabilities/products/stellent/groups/public/documents/content/cms01_055754.pdf Jassm initally reached IOC back in 2003., which can be checked on LM’s website, but since then there were the famous test failures which put a questionmark on the whole programme, even though USAF already had a few hundred of missiles in its inventory. Am not sure where the programme is right now but last i heard is that the problems were being solved… perhaps someone else has some concrete info on current status of jassm?

    How do we explain discrepancies in *publicly* stated ranges for various stand off weapons?

    How does a storm shadow get 250+ km range, kepd 350 gets 500+ km range, jassm gets some 400+ km range and jassm-er 900+ km range?

    Lets keep in mind that storm shadow and kepd 350 are very similar in dimension and shape while jassms are some 30% smaller. Both versions of jassm have the same dimensions.

    So how do we explain the range differences? What are most likely explanations?

    A) Publicly stated max ranges have little to do with reality. ‘over X’ range or ‘xxx plus’ range can often mean two or three times the range. Certain users may require the manufacturer not to state the true range while other users have no such issues or are offering public figures which are much closer to reality.

    B) Stated ranges for each missile are given for different flight profiles. Maybe one missile flies low the whole time while another missile (or version of a missile) flies on a high trajectory. That difference alone could offer 100% longer range.

    C) Internal composition may be radically different. Just because outside dimensions are, say, 5 times 1 meter, that doesnt mean that all of that volume is used for warhead, engine, electronics and fuel. Perhaps one missile uses relatively thin walls with little room for thick layers of RAM, while another uses several centimeters thick RAM, optimized against even wider bandwidth radars.

    D) Engine/fuel technology of one missile is so much more advanced that it really can offer 100% longer range over another missile, with other variables being the same.

    E) All of the above…

    I can’t find the link for the life of me, but perhaps someone can – there was a video on youtube where a burke fired 3 missiles within a second or so, one from the back and two from the front. So rate of fire should definitely be little under a second for the mk41, certainly no slower than a missile each second per launcher.

    Why chinooks? It’s not a LHD. But other than that, what you’ve listed may indeed be the usual peacetime air wing. In war conditions we might see another 12 F35s plus one or two more AEW helos and/or asw helos, depending on the projected threat.

    I guess CVF is designed for relatively slow speeds to begin with. No way it will be able to reach speeds of Nimitz at al. 25 knots should be enough for most missions, save for those where one needs to run for their lives. 😉
