    The B-47 and the B-52 gave us the 707. Who knows what the B-70 would have given us. Sure there were smaller supersonic planes, but the B-70 would have been the template for large civil aircraft.

    There were, oh so many, “Rockwell”, Airbus, Boeing and Tupolev´s airliners with a variable sweep wing for the last three decades didnt they?
    And the latest generation of Embraer´s, Comac´s, Canadair´s, Boeing´s, Airbus and “Northrop” Airliners all look like a gigantic collection of “Batman aeroplane look alikes”.

    It still remains that the leap forward that the B-70 would have generated in aviation was lost.

    What “leap forward”? In what way the XB-70 was a “leap forward” versus the YF-12/SR-71 program? Or the X-15? Or the Space Shuttle?

    Cancelling it set aviation back decades.

    No

    Where are the supersonic transports we should have had 30 years ago

    In what way the USAF building a fleet of B-70´s would bring forth a genereration of supersonic transports? What was the catalist in the B-70 that was not present in the B-58 Hustler, the B-1B, the SR-71, the Mirage IV, the FB-111, the TU-22, TU-26, or the TU-160?
    And what was so special on the B-70 that its existence would bring forth those civilian “Supersonic Transports” by comparison with the Aérospatiale/BAC Concorde or the Tupolev TU-144?
    We had civilian supersonic transports remember? They were freaking expensive to operate, and there was no hint on the XB-70 program of something that would somehow make that particular “niche” (supersonic civilian thingy) cheaper to design, acquire and operate.

    Military science and engineering has always led the way

    Neither the Wright Brothers, Santos Dumont or Elon Musk received that particular memo. And i have my doubts that the Douglas Aircraft Company had received that same memo in 1932/33 when they decided to design the DC-1.

    That is why civil aviation got jets

    And the military got aeroplanes because chaps like a pair of American Bycicle makers, a Brasilian Coffee Grower or a French engineer decided to break the technological edge on their own expenses.

    A trick ?

    There are plenty of supersonic projects in the works today and we will see prototypes in the sky by 2020 and maybe service in 2025. The history books will look at 2003 to 2020 as the dark ages of aviation. The age where lthe fastest military and civilian jets sat in museums. The age where aviation regressed instead of progressed.

    What protoype are you specificaly thinking? The BOOM subscale demonstrator?
    Besides BOOM, i am not aware of one single project that aims to have a prototype of a civilian supersonic aircraft by 2020, the earliest would be lockheed QST X—plane and that would be flying (with a bit of luck) around 2023/24. And i will be pretty surprised if BOOM actually builds and fly the XB-1.
    There are quite a lot of start ups (Spike/Aerion, BOOM, Cygnus, etc) doing sketches in PC CAD but the chances of them getting anything airborne with actual passengers on it would be pretty, pretty thin, the investment to have such an aircraft flying in regular service shoud be on “quite a lot of billions” cost bracket. Untill i see any “major” (Boeing, Airbus, Embraer, Canadair, COMAC, Sukhoi, Dassault, etc) cutting metal i wouldnt bet the farm on a supersonic civilian aircraft hitting the market.

    The fact still remains that there is virtually nothing the B-52 does that the B-70 couldnt do faster and better.

    Except carrying a LOT more payload, longer while doing it a lot cheaper?

    Also doing a little research the bomb carrying capacity, and the range is not that much different between the two aircraft. Remember because of the brilliant compression lift design that the B-70 had, its range was greatly extended.

    The B-70 maximum payload was 25000 lbs, the B-52´s is 70000 lbs.
    The combat range of the thing was 3419 miles…

    The entire USAF “Standard Aircraft Characteristics” documents are displayed at the “Secret Projects” Forúm

    there is a 99% chance that sadly the decision to cancel that brilliant design was undoubtably a political one, which everyone knows is a stupid reason.

    Eh, no

    The first radar AESA JAPG 1 is a very short range detect. Comparison it to the first radar PESA Zaslon’s MiG-31,

    Next comparsion, a fishing trawler with the USS Gerald Ford…
    they are both boats…

    For the moment, the SM6s are heading to only those DDG-51s that have gone through the AEGIS baseline-9 upgrades.

    Thanks for the update

    If an Arleigh Burke destroyer fights a peer surface threat today guess which is its weapon of choice, Harpoon? Nope, short ranged, subsonic. The Burke’s first choice is actually SM-6 which has a secondary ballistic anti-ship capability. It would spam the target with up to 30 missiles, overload its defences and either set that ship on fire or damage it’s sensor arrays with those relatively light warheads.

    The main US Navy anti ship weapons are the MK48 ADCAP´s launched from their Nuclear Hunter Killer Submarines or JSOW/SLAM/SLAM-ER/Harpoon launched from Super Hornets, a force on force peer surface confrontation by an Arleigh Burke would be something that i would imagine the US Navy would strive to avoid, finaly, while you do have a point that the SM-6 brings a very interesting ashm capability i dont think that capability is available today across the fleet.

    The B 52 is not a bomb truck. Its a bomb hay wagon. The B 70, if configured to just be a bomb truck, would have been more efficent. Hard not to be.

    I agree with the poster. The B 52 still has doggy low bypass engines ffs.

    The B-70 would have less range than the B-52, carrying 1/3 of the bomb load, while consuming more fuel and an RCS that could rival the USS Gerald R. Ford.

    And they don’t work as intended like THAAD failures to shoot down NK missiles flying over Japan.

    Hokkaido, Japan, is Northeast of NKorea, the THAAD units are in South Korea.
    Thats like saying that THAAD batteries in Romenia have failed because they coulndt intercept a ballistic missile shot from Kaliningrad that overflew Saint Petersburg in direction to Arkhangelsk.

    Firing skilled workers because you have no work for them could render you incapable of doing similar work later. Those people may have lost their skills or been employed elsewhere, & it would take time for others to become equally skilled. It’s a very inefficient way of working.

    The RN “Astute” program comes to mind.

    First since the B-52 is still a valued aircraft, why wouldnt an aircraft that flys twice as high and 4 times faster be better.

    Because flying and maintaining a mach3 aircraft, one that had no obvious mission and weighted 50% more than a B-52, would have bankrupted the USAF.

    Second, since the SR-71 was never shot down, why wouldnt the B-70 achieve the same results.

    The SR-71 was retired in 1998, the Dragon Lady still flies, there´s a lesson in there.

    Third, with all the large supersonic flying experience it would have had, cancelling it probably set aviation back 30 years. There is no reason we should not have supersonic transports flying all over the world right now.

    It would have been such an invaluable experience for the civilian aviation having a great supersonic airframe flying around.
    Hmmmmmmmmmm

    That greek site looks like an Hellenic version of the Daily Mail… In its front page we have a story about a nineteen year old girl funeral, twins who got convicted on drug charges and so on.
    The chances of the Greek chap who wrote the story having privileged access to the Atlantic Trident reports are just slightly better than having a snowstorm hiting Ougadougou today.
    That article looks like a political piece, one slamming the Greek MOD, the relevant bit being the “hordes of Turkish F35’s”…

    That is absolute and total hogwash. Sputnik and RT both have total editorial freedom from the Russian govt. Abby Martin proved that on the air.

    LOOOOOOLLLLLLLL

    Oh, please!
    Can you one single article just slightly critical, but just slightly critical of the Russian government in any of them?
    When was the last time that RT covered, lets say, Tchetchenia and Abkhazia in any way that is not government scripted?

    Compare that with the “hell ride” that any western government gets from their media…

    Final round of trials ended last year. Still to receive a production order AFAIK (or is in production if that’s changed).

    This, there were some noises that the Kuwaitis would be the first ones to receive them but i am mot aware of any contract till now.

    I’ve never really understood how that’s supposed to work. The aircraft can project PIRATE FLIR imagery onto the Striker’s visor. Okay. But the FLIR would have a limited field of view. Just a forward cone, maybe +/-60 deg azimuth and +60/-30 deg in elevation. According to Scorpion, LDP input isn’t available or planned.

    So how does it allow the pilot to look ‘through’ the fuselage of the EF for the VR effect?

    It doesnt “look” through, the pilot doesnt see images, but only symbols, the sensor used is the radar.

    Cheers
