    Temperature drops linearly with 6.5° per 1000m.

    Not incorrect, but incomplete! Once you get around 65-70,000 feet, the temperature and the speed of sound INCREASE. They increase and decrease based on atmospheric temperatures all the way until you hit space. Saying that the speed of sound decreases because the temperature decreases is not correct, since eventually the speed of sound will increase again.

    As long as the government representing all 300+ million Americans thinks and acts so, then the individual feelings of American citizens towards Israel are utterly unimportant..

    Unfortunately I do have to agree with you there. But the phrase “you Americans” seems to point to the people and not the government, which I’d object to as you know full well that I am in no way a fan of ANY pro-Israeli US policies!

    If they are truely offensive weapons then why would they need hardened silos?
    Used offensively means they will be gone when the enemy retaliates.

    You’re still taking it entirely out of context!

    They could carry AIM-54s on the wings without the underfuselage pallets I think, remember that the lower half of the wing pylon was different if an AIM-54 was mounted than if an AIM-7/9 was mounted.

    On flat terrain a cruise missile is an easy target. Even a system like the SA-8 is very effective against a cruise missile attack. Even modern MANPADs can engage such targets.

    Once they get past the poorly defended coastline the terrain leading to and surrounding a good deal of those nuke sites is anything but flat!

    SOC… regarding your posted link can you explain something to me:

    What exactly makes Iran alone in the world in having silo based ballistic missiles that are clearly not defensive. How can you define Iranian missiles as offensive weapons. Considering the topic of this thread and Israels history with its neighbours and nuclear power stations how can you refer to any Iranian weapon as offensive, let alone their BMs?

    You misunderstand, I was primarily alluding to Taiwan’s TK-I silo-based SAM system, clearly a “defensive” weapon system. Iran is the first non-nuclear power to deploy “offensive” weapons (i.e. not a SAM system, I am comparing ballistic missiles with SAMs here) from a hardened silo. You do have a point, that could’ve been clearer. I may go back and edit that bit. This is a common problem with topics that I have an extensive working knowledge of, I write and write, and everything makes sense in my head, but I end up having to go back and re-explain things. Most of the time I catch it before I actually post the article, but sometimes I misfire.

    Are you sure that’s an Su-34 in the photo? It’s clearly got the side-by-side cockpit and is being built at NAPO, but for some reason the nose doesn’t look right. Granted the chine fairings aren’t there yet but the radome looks like it’ll be more round than the oval shape of the Su-34. New weird variant?

    as if I haven’t asked enough already :p, official specs for R-73 variants……

    Rosoboronexport gives +/- 45 degrees for the R-73E, with a max range of 30km and the ability to engage a target maneuvering at 12 g. The specs released with the images of the domestic R-73 being shot backwards from an Su-27 claim a +/- 60 degree capability and range of around 12 kilometers.

    With conventional cruise missiles though you’d have to fire a LOT to cover the number of targets

    Not really, there are fewer than 10 critical facilities, and you don’t have to blow up every building to knock a facility out of action. The only problem is the geographical distances between the targets, which would negate any serious attempt at an aerial assault using fewer than, say, 50 aircraft!

    not to mention the most sensitive, nuclear related targets would probably laugh at a cruise missile because of their hardness

    All they’d need is a penetrating warhead. Not unheard of. And since the Tor-M1s are only deployed around Natanz according to media reporting, the missiles will probably be laughing at the HQ-2s and HAWKs defending the remaining sites. Iran’s SAM network is a joke until they get S-300PTs into operational service. S-200s can threaten ISR aircraft and other HVAAs, but that’s pretty much the only serious threat.

    I guess a ballistic missile strike against Israel would be fair-game IF Israel bombs Iran correct?

    Absolutely. That’d be precisely what I’d expect to see.

    How many variants of the “Shahab” BM with the necessary range are at Irans disposal?

    Probably only the Shahab-3 given the distances involved. Read more about Iranian ballistic missiles here: http://geimint.blogspot.com/2008/02/iranian-missile-silos.html

    As featured in Jane’s Missiles & Rockets, of course 😀

    Sorry, that just doesn’t get old!

    Well wonder what the reaction would be if who knows how many Iranians were to die of such an attack?

    You can put money on the term “Persian Holocaust” being plastered all over the media.

    Four AIM-54s was a common loadout back then. They just didn’t like to launch with a full six as it caused problems with weight restrictions getting back on deck. Carrying the AIM-54 near Libya would’ve made sense anyway given the test results showing the apparent ability to smack MiG-25s. Note that I did say apparent.

    If they really want to do this then their best bet is to fire cruise missiles from their submarine fleet. Move a few into the Persian Gulf and let fly. Solves all sorts of problems and raises confusion as to who actually did it, making Iran’s retaliatory options a bit muddled. The question then becomes whether or not Israel has the willpower to do this without informing the US. It also solves the problem of having to deal with many geographically separated sites.

    That is a bit odd. 20 BVR AAMs is a very small stock even for their small SHAR fleet. Maybe they were confused and got the Derby buy mixed up with maybe a Popeye buy to replace the Sea Eagles? Also, firing the missile in LOBL mode seems to indicate that they either haven’t upgraded the FCS to support the midcourse datalink or aren’t going to do so.

    The speed of sound does eventually increase again as you get around 70,000 feet. It does have to do with changes in air temperature, that part is correct. Once you hit the stratosphere, the speed of sound increases gradually until it hits around 640 knots at 155,000 feet.

    I wasn’t doubting that India had the Derby, just voicing my irritation that nobody seems to be taking the proper photos 😀 Israel on the other hand, I don’t know if they’ve actually found a use for it or not given their AMRAAM stock.

    In theory. No evidence of actual carriage by the SHAR yet, and no evidence of an operational F-16 user either.

    Ah, I hadn’t noticed that (I was not the deletor in this case). I’ll fix the error.
