    nah…a helo cant keep up to escort a strike package,
    and it cant fly far out on a threat axis either,
    its stuck on top of the carrier group so while not giving away exact coordinates,
    it gives a rather good idea where the carrier group is.

    Escort a strike package? Yeah better to give away the exact coordinates of the incoming strike group that the vague “box” in which the CSG is located.

    AEW aircraft fly racetracks at varying distances from the carrier. It would be difficult to get even a vague coordinates of the location of the carrier within a several thousand square mile “box”.

    I would have thought that with the same number of aircraft on deck ready to launch, that a STOVL carrier could launch the planes quicker than a CATOBAR carrier, no need to line up at the cat etc, also a STOVL carrier could land planes quicker, with multiple landing slots as opposed to one set of arrester wires.

    So assuming that the maintenance requirements are the same +/- for the B and the C between sorties, with no faults reported in the previous flight, implicitly the STOVL Carrier must be slightly quicker at generating airborne formations.

    What is the minimum safe time for an F35B to start its launch run after the previous one? Less than the cycle time of using a catapult…

    On the contrary, CATOBAR carriers tend to be larger. The QE class is an exception and could easily have been fitted with 3 cats. Given the cyclic operations (launch cycle followed by recovery intervals). A CATOBAR carrier can spot ready (CAT I) aircraft and put 2-3 in the air every ~ 40 seconds. With STOVL ops, the aircraft have to be spotted near the rear with sufficient spacing. It is doubtful if more than 4-5 can be spotted for a takeoff cycle at a time.

    The QE class is a larger (and has an angled deck and considerably more spotting/ready space than previous STOVL carriers) but you still run into the issue of sufficient rolling takeoff space for ready aircraft. The F-35B has a 600 ft rolling takeoff spec for the USMC, likely 400+ feet for a ski jump as fitted to the QE. Depending on required spacing for the F-35B, the QE class would have 500+ feet for spotting/ spacing ready aircraft. That is a heck of a lot more than the USN America class ships. But launch interval would be key. Even at a brisk 15 seconds between takeoffs, that still would a slower launch cycle than a CATOBAR carrier. Not to mention, the loss of ability to go to “flex deck” and have launch and recovery taking place simultaneously.

    Additional- UK STOVL KPP is 450 feet, had to confirm that. USMC STOVL profile is pretty stringent- tropical day, 10 knots WOD (originally 550 feet- then 600) I’m too lazy to look up latest DOT&E to see if USMC STOVL distance was adjusted back down (it was estimated at 568 feet in 2012).

    Besides that, I am not aware of KGB having ever been accused of war crimes or anything remotely similar.. By that logic it’s no better or worse than CIA or any other intelligence service in the world.

    Unintentionally, this has to be one of the funniest lines ever uttered on this forum.

    The KGB wasn’t founded until 1954, it’s predecessor, the NKVD, was accused of many. I think several thousand Polish officers’ families, hundreds of thousands of Soviet soldiers’ families, etc, from WWII would disagree with that flippant commentary.

    I would say that the main victims of the NKVD were the Soviet people. War crimes as a category are a bad example for “proving” a nation or organization guiltless of crimes. The winners don’t get charged, and accusations don’t go anywhere. True for KGB, CIA, whatever. Besides, it wouldn’t be hard to find a large number of people in certain nations that would accuse the CIA and KGB with crimes during Cold War.

    I am not sure if the analogy is a good one.. ME countries have for a long time bought a mix of US and non-US fighter aircraft.

    However the problem they are soon facing is that Western Europe will not be able to supply 5. gen a/c, only 4.5 a/c (Rafale and Typhoon). Thus it would make sense for them to find a way to obtain non-US 5. gen a/c. In addition to the “mixed force” argument one additional argument could be that they are currently banned from obtaining also the F-35.
    ?

    Problem is that said aircraft does not exist. The timelines involved in developing a 5th gen airframe virtually preclude the possibility of UAE receiving a joint fifth gen aircraft before 2030 (generously). The possibility of joint development based on a Mig-29 could be delivered in a timely fashion, but then it would be neither: a fifth gen airframe, nor a significant capability upgrade from their F-16’s.

    Paywall. Can’t speak to the laser designator, but SDB-II is due to be intergrated in block 4. Not sure why this is news now.

    Ploy…. the F-35 isn’t for sale in the gulf due to Israeli assurances. Gulf states tend to sign all sorts of agreements, this one seems as plausible as the sale of diesel electric submarines to Taiwan that US congress approved under the Bush admin. One problem, the US doesn’t produce those, nor does Russia have a single engine light fifth gen in the pipeline.

    F-35 numbers are off-

    F-35A empty weight (per last DOT&E)~ 28,990 lbs (13,109kg) + ~ 9,250 lbs fuel (4,196kg) + 2204 lbs (1,000kg)= ~40,454(18,349kg).

    With 43,000 lbs of thrust, that is a thrust to weight ratio of roughly 1.075.

    Not that static thrust to weight ratios at sea level give anything more than a ballpark comparison.

    Pierre Sprey believes the Rus can see em

    Spray also takes credit for an aircraft he had no part in designing. Furthermore he claims said F-16 is more maneuverable than the: F22, Su-35….. on and on.

    No, it isn’t.

    JSR…. enough said. Weigh overriding the 50% of posters who have him blocked (that they have to read when u quote him) with the merits of this discussion.

    After watching the video , it seem like they pit 8 Blue air against 20 Red air. According to the general Red air has jamming and SAM support. Not sure whether they had AWACs or not.
    Red air are most likely the 64th and 65th Aggressors Squadrons, consist of F-16 and F-15]

    No 65th aggressor squadron anymore.The number of “enemies” blue air faces on any given sortie can be large with red air regenerating.

    Gripen E uses Gigabit ethernet for data transfer…

    Gripen E uses commercial ethernet and 1553B databus networks:

    Look at the system architecture up close and you will see.

    Except that Fornof was retired when he did this speach to a “club” (praetorians)

    I don’t believe he was. If I remember correctly, he did retire soon after. The video flap basically ended his active duty career. He served as commander of Nevada ANG in 2011.

    He was still director of requirements and testing USAF warfare center in 2008( looked it up).

    KGB, let’s get this straight. You are using the much maligned debriefing from col. Fornof (not that he was wrong, just that his debrief was based on impressions) to support the idea that the Su-30 Mki is as maneuverable as the F-22? Did you get the part about F-15’s drilling their brains out with guns going in the vertical? Good non-example. What’s next hud footage of the Rafale killing the F-22 to prove the maneuverability of the Su-35 vis a vis the typhoon? They are pilot impressions from exercises, experience counts more than the platform.

    Anyone who is capable of using google with a modicum of competency could have found three to five research articles about geolocation using IIR for everything from rifle fire, mortars, and missiles.

    Very well established there oblig, so much for trig, back to school for you.
