    Concorde used afterburners only to save fuel. Accelerating through the transonic drag hump with afterburner used less fuel with afterburners than in dry thrust, because of the much smaller length of time spent in the high-drag zone if AB was used. After that, it was dry thrust to accelerate to – and stay at for a couple of hours – Mach 2.

    The Blackbird had an engine designed for maximum efficiency in afterburner. At high speed, only the afterburners operated, the turbojet core being throttled back & mostly bypassed. It then functioned more like a ramjet than a turbojet. A one trick pony – but very good at that trick. It is known to have flown 3870 km at an average speed of 3420 km/h, in 67 minutes. That was afterburner (if that’s the right term for what those engines did) all the way.

    also the concord uses ab for take off
    i didnt know that about the bbird, thanks for that

    It’d be interesting to know how long Blackbird stay on afterburner, or Foxhound, of Foxbat, or Concorde for that matter, or….[insert]

    LOL, concord had afterburner on in general fight would be news to most people
    why dont you google and tell us what was the mission thrust and service life on black and fox as well
    i cant wait for your links, that rafale 88 engine would be nice to see the times ratings on too, just better than the russians would be my guess

    with max burner time, the service life of a jet engine is counted in minutes, full military power isnt much better
    99% of the time everyone goes subsonic

    JackJack the ADF reserved force interdiction in the far north as Pigs without escort. Sure for the regular strike role they’d use coordinated force projection with tankers and Hornets, and wouldn’t do that without moving frigates into the area too. I’m talking about the penetration strike role, not fisticuffs in extended hostilities. This point was covered in the RAAF own published magazine back before the purchasing agreement was finalised (one of the options tabled was trying to update the Pigs).
    Also I’m aware currently the RAAF is satisfied with the SuperHornet replacing the Pigs, they weren’t about an F-35 only purchase however.

    unescorted interdiction would be right when all the air has been taken out
    if there is a possibility of contested air, they would be escorted

    for antiship, we are going with the internal NSM from norway

    for years the f111 had to have hornet escort, so it couldnt go anywhere the hornet couldnt go, so your point is mute
    the SHornet can self escort its longer range than the hornet, as can the f-35
    then we add tankers, as had to be done with the hornets

    its even funnier when you add the much said statement
    “the f-35 is like the fa-18 and f-16 in performance”
    anyone would think it was deliberate omission of the naysayers of their defined supercruising fa-18
    also note they always talk about drag on a clean wing and not one loaded with weapons and fuel needed for a mission

    An interesting read, thank you.

    Its also interesting to have a look at Eurofighters view of 5th generation, the checklist showing the F-22, F-35 & Typhoon is rather interesting too.

    What are your, or anyone elses thoughts on that?

    *Expecting some fans of F-35’s & F-22’s to step in with LM quotes*.

    why didnt they give APA as a source ?
    they even did pictures, a bigger list and just as creditable

    SH was pulled out by Boeing who cited that the requirements for this F-5 replacement were too easy and they felt that the SH was overkill and consequently wouldn’t be chosen. The 3 contenders who were evaluated were the Typhoon, Rafale and Gripen D.

    you’re right boeing did consider the SH overkill
    i heard that it was 2 fold, first was the allowed budget and second was the mission set required
    on allowed budget and mission set, the gripen is the likely winner

    that au75m is a full production price, not the LRIP
    best if you put all your assumptions on the f-35a price in a detailed assement and i will help you send it in, when your assesment turns out to be true, you will have the 1/2m a year job, come live on a sunny beach and we can sack the nohopers we have now

    are you available for a contract to teach our defense dept how to do their job ?
    the f-135a ~au75m flyaway is as good as the ~au60m flyaway for the Sh’ornet
    we have padded the price to the current projected us65m flyaway for the f-135a
    i didnt see the flyaway for the f-135b but that would be more
    the partners prices dont reflect the USprice debate that is happening, as their obligations to R&D have been met in the original contract
    the usa is paying more than the partners
