    Interesting. The JHMCS at least the earlier version if not II is on the PAF F-16s. Recently there was a rumor that PAF was using MAA-1 Pirhanas with the JHMCS. Does anyone know if that is possible? If not, it would be a good way to eliminate that rumour and the reliability of the source…

    http://en.wikipedia.org/wiki/MAA-1_Piranha

    Other articles mention a helmet sight and off-boresight capability.

    It seems to have a seeker from Kentron, which has manufactured a range of AAMs over the decades that are slaved to helmet sights.

    I’ve no idea whether the seeker is from the Kentron Darter V3B or V3C model, but looking at the off-boresight angle given, I suspect the V3B.

    The follow on MAA-1B seems to have had the V3C seeker, with greater gimbal movement and off-boresight angle.
    I’m not sure what the status of this missile is though, as the new A-Darter has been chosen by Brazil.

    So it appears that the Piranha uses a helmet sight, but I’m not sure about the JHMCS.

    And I agree with your assessment. I meant no disrespect to you

    Me neither to you, Roovialk.

    I hope I didn’t give that impression.

    Just that I suppose we can’t be sure what type of shoes they are.
    They have done what seems to be a good job resurrecting, outfitting, and kitting up that rusty tub, but I also have no doubts there is a long road ahead, with mistakes and corrections.

    Can you ‘dig’ this? What you read below is the reality of the flightdeck and there are no shortcuts for any person or nation who wishes to become proficient with carrier operations. Pointing out a PLAN gaff is not a dig. Even the most experienced navy suffers accidents. China is just starting out on a long climb. And re-furbishing an old carrier is the easiest part of the climb.

    YOKOSUKA NAVAL BASE, Japan — A sailor lost his lower right leg after being pinned under the wheels of an F/A-18 Hornet on the USS Kitty Hawk aircraft carrier on Wednesday.

    The 19-year old sailor is a “blue shirt” airplane handler in the carrier’s V-1 division and was on the flight deck at 6:15 p.m. when the accident occurred. His name is being withheld for “privacy reasons,” said Kitty Hawk spokesman Lt. Cmdr. Terrence Dudley.

    “The Hornet was basically being parked on the flight deck,” Dudley said. “The case is still under investigation but we know that the sailor managed to get his leg trapped under the wheels.”

    I’m aware that the flight deck is a very hazardous place.

    I didn’t call yours a dig, but if you look earlier in the thread, there are a couple of those.
    I merely pointed out that you assumed that they weren’t wearing steel capped shoes, when my link shows that you get all kinds of steel capped shoes, many of them coincidentally made in China these days. You simply cannot assume they aren’t steel capped because they aren’t black in colour like they all were back in the day.
    Thus, you actually have no real proof that it is a gaff or not, which is my entire point. It’s an assumption. They may or may not be soft shoes.

    The news report you linked above sounds as if wearing steel capped boots wouldn’t have saved his leg.

    Either way, it will be interesting to see how they get on over the next few years.
    I suspect any indigineous carriers will only be laid down in the next few years, and benefit from their experience gained between now and then.

    To be honest Swerve I think Rooivalk has a point here….granted you can get steel toecapped soft shoes….but they are just that though – soft shoes. On a ship you are forever stepping over or through obstructions, jumping off platforms or fitting yourself around, usually heavy, machinery that is spinning, bouncing or is in some other fashion just waiting to send the unwary sailor base-over-apex. Ankle protection from a decent pair of boots, or even a modest pair of boots as per RN issue, is what you want to have and the Chinese chap with the trainers on is certainly not getting that…toecaps or not. Not the end of the world, but, slightly surprising.

    I see your point about ankle length boots, but as Swerve said, we can’t say that they aren’t wearing steel capped shoes, which was Rooivialks point.

    Personally, I think if they can turn an empty rusting hulk like this…

    …into something like this…

    http://i1268.photobucket.com/albums/jj563/venoid/carrier.jpg

    …I personally would give them the benefit of the doubt that they will get it right, sooner or later, and not join the cheap digs at them that seem to be a feature from some posters. (Not you, Jonesy).

    Yeah, because you simply don’t get steel toe capped trainers. They don’t exist.
    What are the Chinese doing?
    Don’t they know…… etc etc.

    Unless you’ve gone and felt what shoes the guy is wearing with your hands, this is not a good argument.

    The qataris have tried to buy advanced Russian weapons as recently as last year (with the “caveat” that Russia doesn’t sell advanced weapons to Iraq). What they buy is mostly linked to regional and international politics rather than the weapons themselves.

    This x1000.

    Like Saudi Arabia, a lot of defence purchases are used as foreign policy implements.
    They use their purchases to keep the US and the UK sweet, compliant, and onside, as the duplication of combat platforms within their airforce neatly shows.

    It has very little to do with the capability of one platform over another.

    That’s truly rare. The hunter was a good plane, its record in the subcontinent doesn’t do it justice.

    The Hunter was a good plane.

    However, it’s weak point was that it had a poor fuel capacity, and even though later versions added extra integral fuel, it was never the Hunters strong point.

    He didn’t match Marsaille. Also, he fought in the jet age, chance is there for faster kills.

    It makes no sense whatsover to say “he fought in the jet age, chance is there for faster kills”

    wilhelm-

    The F-5 doesn’t have the capacity to generate much more than the 2.5kW and it takes four times the fuel flow over its cruise flow rate to reach that sum. The F-5’s used a 24v system that didn’t have much battery backup capability either. So antenna size may be important, but the system still needs its power which on small jets like the F-5 is no trivial task.

    Are you sure?
    2,5kW is roughly the power a domestic lawnmower uses.
    I can see that batteries, inverters or ancilliaries systems may struggle in that tightly packed airframe, but the engines should surely not struggle with a 2,5kW power requirement.

    It isn’t – http://www.globes.co.il/serveen/globes/docview.asp?did=367382

    Once again, comprehension skills are important.

    According to the reports, Israel Aircraft Industries subsidiary Elta is offering EL-2035 model radar, which the say was originally developed for the Lavi.

    I know we all have different standards, but “according” to un-named “reports” and “which the (sic) say” in a generic non-aviation business article is certainly not what I would consider definite confirmation.

    There are plenty of articles and websites like the one you’ve posted (thanks for that by the way) but no definite confirmation that I’ve found.
    It does make sense though that the 2032 origin lies in the 2035.

    Antennae size is way more important.

    The average radar doesn’t use that much in relation to engine power, as can be seen above in in Mspheres post.

    The F-5 has a particularly slender radome.

    As wiki (I know) says about the AN/APQ-153 radar of the F-5:

    Required to fit into the tight confines of the originally radar-less F-5, the system offered relatively simple air-to-air modes and a short detection range.
    The antenna was necessarily small, a 12 by 16 inches (30 cm × 41 cm) parabolic dish.

    The replacement AN/APQ-159 for the F-5:

    The APQ-159’s primary upgrade was the addition of a new planar phased array antenna, replacing the -153’s parabolic dish. This made the antenna smaller front-to-back and allowed it to be pointed to higher angles within the nose. It also greatly reduced the sidelobes, which improved gain and allowed the range to be greatly increased from the -153’s roughly 10 nautical miles (19 km) to the -159’s 20 nautical miles (37 km).

    MSphere, that 2032 version above with the typical detection range of 18 NM seems to be the smaller version of the 2032, as tailored to fit into the small nose confines of the Chilean F-5 upgrade. That typical detection range tallies with the information I have of the F-5 upgrade.

    There are 2032’s with longer ranges as far as I’m aware.
    For example, the Cheetah C has a bigger nose diameter with far more avionics space in the extended nose. It also carried the R-Darter, which had an operational range of 60km. This is also supported by some of the scenario exercises carried out with other airforces, against Su-27s, F-15s, and F-16s

    Thanks MSphere.

    I thought I’d left something out.

    That’s not a bad record, leveraged out of the original Lavi programme.
    Just a side note. I think the original Lavi radar was the Elta 2035, with the 2032 being a derivitive.
    It’s difficult to confirm though.

    British forces are there only to counter Argentinean plans. No Argentinean threat, i.e. not just an official policy but an end to harassment, inflammatory rhetoric, & military posturing, & the UK may start to reduce its forces.

    Lets review the situation.
    A & B live in peace for many years.
    B sees no need for more than token defence against A.
    A attacks B.
    B fights back & eventually wins, at great cost & after initial losses.
    B strengthens its defences, but not to the point where an attack on A is feasible.
    According to you, this necessitates A planning to fight B.

    Can’t you see the flaw in your logic? You talk about naivety, but your position seems to verge on paranoia.

    You appear to have conveniently forgotten to include that A and B still claim for themselves what created the war in the first place.
    A hasn’t dropped their claim.

    Let’s cut to the chase, and leave out the nursey rhymes.

    1. Do you, Swerve, believe that the Argentine Air Force strategic planners never, ever, even remotely consider the Falklands when putting together plans and what sort of equipment they would want?
    2. Do you believe the same if the defence budget went up to 2 to 2,5%?
    3. Do you believe that the British strategic planners never, ever, even remotely consider the Falklands when putting together plans and what sort of equipment they would want?

    They should, just as British military planners have ignored the potential flashpoint to their west for several decades, except as a source of terrorists. Can you imagine it? There’s a state which until 1999 had a constitution which declared that its territory included part of the UK, & whose politicians regularly referred to that claim on British territory, & yet we didn’t plan to defend against an attack from it.

    The Falklands is a potential flashpoint ONLY AS LONG AS THE ARGENTINEAN MILITARY MAKES IT ONE. If they do not plan to make it a flashpoint, there is no need to plan for it. Why is this so hard to grasp? It’s like Morocco deciding that the Canaries is a potential flashpoint, & planning for it. That would turn it into one. It’s a self-created problem.

    The fact is that Argentina and Britain have gone to war over this within our lifetimes.
    Argentina has not relinquished their claim.
    Britain deploys far more forces there than in 1981, and also poured money into the new airbase, Mt Pleasant.

    It’s not like Morocco and the Canaries at all.
    Morocco has not even officially expressed a claim, let alone gone to war.

    Argentina has not relinquished its claim.
    They try to retain a carrier aviation capability, the current government parsimony notwithstanding.
    Britain maintains far stronger forces in the area than before the war, yet Argentina “They should, just as British military planners have ignored the potential flashpoint to their west for several decades”.

    Pull the other one.

    I’m flabbergasted at the naivety on display here.
    Britain has plans around the Falklands too, and part of that involves having a minimum amount of seaborne airpower and submarines available.

    I understand some will wish that the Argentinians don’t consider the Falklands in forecasts, but anybody with a knowledge about how the military implements it’s future strategies and requirements will find this simply laughable.
