    no it doesnt , your statistical comparison would no be accurate if you try to calculate engine reliability from f-16——->f-35 by substituting mirage instead of f-16

    In talking about the and i emphasize RAAF’s single engine fighter ops history, how am i substituting the Mirage for the F-16 when we have never operated the type?

    Also the F-16 and F-35 engines are fundamentally different powerplants, so how do you compare the two?

    What expereince do RAAF boys have operating US produced single engined fighters ? Lockheed and USAF relied on statistical data of previous gen fighter engine to look into what the next gen of fighter engines would be like , it is wiser to look @ same force level and a product from similar supplier for comparison .

    That smacks a little of US “ours is better than everyone elses” arrogance im sorry.

    Although not a single engined type, we have been operating a US aircraft with US engines for nearly 40 years, the F-111.

    so id say we have quite an understanding of operating US built & engined aircraft in our environment.

    also look back into RAAF history and youll see that we also have taken a US designed fighter and made it into something even higher performing and more capable than its US counterpart.

    What unique Enviromental conditions the RAAF birds are custom to that arent their on carriers or out at expeditionary bases such as Middle eastern deserts ??

    ah but are those aircraft intended to operate non stop for 40 years in those conditions? the answer is no.

    deployed aircraft are rotated back to theyre home bases, carrier aircraft return to theyre shore bases, our F-35’s will be in those conditions permanently without respite for theyre ENTIRE service lives, making that unique in comparison to US operation of fighter types.

    USN has had similar concerns however even they are now comfortable , for them it would be imposible to land without the engine and it would mean almost certain loss (cant crash land) , however statistical evidence points that safety record of Single engined fighters when it comes to ENGINE losses ( USAF operation F-16’s) was actually at par or better to the F-18 Fleet .

    I am coming from the RAAF single engined fighter record, not the USAF’s.

    our loss rate for single engine fighters due to ENGINE failures has always been significantly higher than for an operator like the USAF, excluding our military airbases we have incredibly few airports and landing areas that can accomodate a fighter aircraft, thus elevating the risk level of losing an aircraft.

    The other side of the coin is the now greatly increased reliability of modern fighter engines, but again the engines in question were not designed to permanently be based in conditions of the type that prevail across our main fighter stations in the Northern Territory and top end of Western Australia, also quite a few of the aircrew i have spoken to have reservations on going to a single engined type.

    F-35 is a pretty good F-18 replacement for the Aussies , for a true F-111 type aircraft unfortunately their aint much that exists that also provides modern 5th gen features such as stealth and integrated avionics etc . Aussies have a unique requirment perhaps if filling the same requirment is considered such high priority they could invest 6-10 billion US $ in asking LMA to make for them a bigger F-22B (akin to F-15E) with greater range , speed and greater payload .

    im sorry but the F-35A just isnt the ideal fighter for this country, though a capable replacement for the ageing F/A-18A/B fleet, there was no proper evaluation process before the selection was made, indeed the officer appointed to oversee the fly-off for the RAAF’s next fighter was ordered to close the competition before it had begun and ordered to select the F-35A.

    The single biggest problem with the F-35A for Australia is one that cannot be changed, it is single engined, when it had long been identified as a requirement that a Hornet rplacement MUST be twin engined, the reason being due to our few operational flying bases and the great distance between them, added to the range at which most ops are conducted, the loss of the engine near guarantees the loss of the aircraft, whereas with a twin engine design this is less likely with a single engine loss, the last single engined fighter operated by the RAAF, the Mirage III, suffered a high loss rate due to engine failure, indeed over 10% of the total number procured (14 out of 108) were lost to engine failure, and at the end price per aircraft the F-35A is looking to have this is something the RAAF can ill afford.

    As to the eroding of capability it is thus, the RAAF are being forced to pension off the F-111 fleet 10 years ahead of schedule to take on the Super Hornet as an “insurance policy” against the late delivery or indeed total cancellation of the F-35 programme, which with most of the Hornet fleet having exceeded 90% fatigue life consumed and only being barely able to last until the F-35 introduction through reduced flying hours and structural modification, should the F-35 be delayed it could potentially leave the RAAF without an operational air superiority type, a situation that would be an utter embarrassment and yet would be entirely due to the culture of mismanagement that has prevailed throughout defence in the last 10 years.

    I personally hope that the RAAF doesnt end up with the F-35A as its sole combat jet (BaE Hawks aside), i am utterly disgusted already by the sacrifices being pushed onto the RAAF to accomodate the F-35, they are massively eroding the capabilities of this air arm for one fighter, at that a fighter completely unsuited to our somewhat unique requirements.

    XD818 was the first to drop a thermonuclear device during Op Grapple on 15 May 1957 off Malden Island – the first airdrop of a British nuclear weapon was from WZ366 during Op Buffalo at Marilinga on 11 Oct 56.

    Thanks for the clarification Philip, i shouldve mentioned that.

    “F2H-3 …. and racks were provided for two 500lb OR EIGHT 250 LB BOMBS” (my emphasis).

    Chris

    Incorrect, its weapon loadout was either 8x 60lb HE warhead rockets or 6x 60lb HE warhead rockets and 2x 250lb bombs, the aircraft was not rated to carry 500lb weapons and even at the combination rocket/bombload it was struggling.

    cheif reason for this was F2H’s poor thrust to weight ratio, with a total of 6,500lb thrust and a dry weight of some 13,200 lb it was already in trouble, when at its nominal combat weight of 24,000lb you can imagine that with by then with the thrust to weight ratio at about 0.25:1 its really going to struggle just to get off the ground.

    Best thing to do is get a ticket to S Afirca soon 😉

    Soon being the operative word here, the word on the grapevine is Mike’s airworthy spares stock wont hold out too much longer.

    reallly??? how and when did that happen, and how did she escape the axe?

    so the legend goes, when the Valiant fleet were being scrapped en masse, XD818 was due to be the next in the line for the chop until someone of a substantial rank happened to recognize the serial of the aircraft as having been the first to drop a British atomic weapon and ordered the aircraft be placed aside untouched until it could be properly cleared with theyre Lordships for preservation

    after the switch from high to low level flying, this change in operational proceedure also laid rest to the victor as a bomber. the low level flying accelerated the fatigue on the wingspars. what brought it to the Raf’s attention was, a valiant coming into land, the crew heard a MASSIVE bang, and thought something had fallen off. after having landed it was obvious that one of the wings was drooping considerably, and when the engineers got inside, the spar was found to be cracked/snapped. i believe the whole fleet was immediately grounded after this discovery. i think all of the valiants bar one or two, showed serious fatigue in the wingspars.

    i would have said one of the main reasons that, XD818 is still in one piece, would be that it dropped the first british atomic weapon.

    and even then XD818 came within mere hours of scrapping

    That sounds brilliant -can you let us know more?

    With respect for privacy of the current owner all i can tell you is that it is an Australian B.Mk20, it isnt the a/c that makes up my username, A84-232, as the owners of that a/c (Avalon Airfield) were not interested in selling it.

    The a/c i am negotiating for was one of the last to leave RAAF service, it has a combat record having served in Vietnam, it is not in running condition presently but the airframe is sound with a substantial amount of fatigue life remaining, my intent is to return it initially tp ground running condition pending a survey and budget estimate for a return to airworthiness, as there are currently no B.Mk20’s flying, a crying shame i think.

    I believe that even if the work was financially viable (we struggle as it is), we would still not be able to fly for a few reasons. Firstly the CAA would have to say yes. Then BAE Systems would have to give the go ahead as they own the Design Authority for the aircraft, we would also have to get marshals or another similar company to provide the engineering advice. These three could be possible with enough money, the next hurdle however isnt. Rolls Royce most probably would not support the mark of Conway that is in the Victor (CO17). It is different to the ones in VC10’s and aside from this, we don’t have any spare engines. Additionally we don’t know the location of any boxed zero timed conways, or indeed any other victor conways, short of nicking them from 715, and I don’t think the lads at Bruntingthorpe would be too happy with that!

    Its a bleak outlook for flying the old girl, and it is a shame, however I think you can agree what we do is the next best thing. 🙂

    Ollie

    oh i do agree what goes on now is the next best thing to a flyer, bit of a shame that there isnt the opportunity to fly her again though, a Victor / Vulcan formation would be quite a sight.

    good to see you again 320, been a while since the closure of the public TVOC boards!

    Absolutely. Apart from her being out of fatigue life, there would be nothing to stop us pulling back the stick and flying her somewhere. Apart from the jail term when we landed that is. We maintain her to an airworthy standard, because that is the best way to preserve the systems and the aircraft, in addition to providing that extra safety margin. We don’t treat the runs as taxi runs, they are, in essence aborted take-offs.

    Much the same practice as the Lightning lads at Brunty, though i think the Victor is probably a little easier on the knuckles!

    i did read talk somewhere that it would be possible to extend her fatigue life out to 200 FI, therein leaves the question if the work was financially possible of course, would the CAA allow her to fly if design authority could be had from the relevant parties?
