    I read something about Tactics onces.
    Its inluded the typical merge maneuveres. But sometimes pilots choose to go into the “Egg” vertical, i think this maneuvere is not used as much these days.
    But reading about it, it was belived that an F-16/F-15 pilot should very much deny or not do such verticals vs any potensial Su-27 and Mig-29 jets.

    Could this be due the the slow speed handeling, and that the Russian fighter was able to take advantage when coming around the top of the Vertical”Egg” due the lower speed?

    The “egg” in terms of ACM tactics is not a specific maneuver. It is a concept called the “Tactical Egg” and refers to the general idea that a fighter should not execute maneuvers purely in the horizontal or vertical:

    [ATTACH=CONFIG]216105[/ATTACH]

    The idea is that if we consider a point in space, and the fighter is executing maneuvers on every possible planar that intersects that point, then the shape drawn by those maneuvers becomes egg-shaped. This is because gravity assists the aircraft in coming over the top of a loop, but works against it as it pulls out of the bottom of a loop.

    More generally, the “egg” shows why relying purely on E-M diagrams is not necessarily a good indicator of real-world turn performance, because gravity affects turn rate and airspeed bleed rate if a maneuver is done outside the horizontal plane.

    In that situation there was not even a justification to bring down an Iraqi helicopter. By cold logic a crime and not just a tragic mishap.

    Negative. The UH-60s were operating north of the 36th parallel, in the northern no-fly zone. That no-fly zone had been established jointly by France, the UK, and the US in support of UN Resolution 688.

    Link to article about first AESA equipped F-15Cs becoming operational in 2010:

    Minor correction: those were the first AESA equipped Air National Guard F-15Cs. The USAF had 18 F-15Cs with the earlier APG-63(V)2 AESAs operational as far back as 2000 based at Elmendorf.

    Nice new look. I like that it’s fresh but still works the same in terms of organization etc. Nicely done.

    One quibble / request: would it be possible to make posts by users on your ignore list smaller? They are now a lot bigger than they used to be. It would be nice if we had the option not to see them at all, really.

    So in the 80s and 90s USMC A 6E and F/A 18 line pilots did carrier qualification landings, including night carrier landings, as a standard part of their training?

    Yes. USMC squadrons have operated from carriers for decades. And when they do, they have to be proficient at the whole spectrum of ops including night landings.

    It really became a standard practice with the “TacAir Integration” plan that started in 2002, due to a shortfall of fighters at that time – dwindling numbers of F-14s, no A-6s, and too many hours on F/A-18s. For a time, every CVW was assigned one or two VMFA squadrons of single-seat F/A-18s.

    With the F/A-18E/F in wide squadron service, that has been reduced somewhat as the need has been reduced. The trend has been to get legacy Hornets with lower flight hours / lower arrested landings into USN squadrons rather than wholesale USMC squadrons onto carriers.

    What you did was generalise from your experience with one subtype (operated by no other air force) of the engine on a subtype (operated by no other air force) of an aircraft, operated in different flight regimes to all the other users, to all the other types & subtypes & combinations thereof & say “it’s crap”, although none of the multiple other users have had the same problems.

    Funny, I only saw him refer to “USN Adours” in his post. Not sure why you’re being so defensive on the in-general Adour’s behalf in any case. From the USN’s perspective the engine is crap, many other aircraft with other engines have no trouble operating with that regime. If the USN were operating the aircraft outside of agreed-upon parameters, that would be one thing, but in this case the manufacturer and the operator agreed ahead of time, yet the engines are not living up to their billing. So it’s pretty justifiable to call them “crap” in that instance. The fact that the engines don’t have problems with other operators who use them in a less demanding way is irrelevant.

    Is there any evidence of PLAN aircraft, specifically J-11/J-15 carrying out buddy refueling? I was not aware of any.

    I don’t know of any either. I have never seen any Chinese Flankers with buddy tanks. Air to air refueling is relatively new to the PLA, I believe they really only started doing it circa 2010.

    However, we do know Su-33s (and of course other Flanker variants) have at least been flight tested with UPAZ-1A buddy pods, so it’s certainly possible for the PLAN to develop this capability, though as we said before we don’t really know whether they could carry a useful fuel load in STOBAR.

    Either way, the point about a lack of organic tanking is well taken. A lack of any such capability will force the J-15s substantially reduce their operational radius (already reduced by STOBAR takeoff limits) in order to maintain a safe fuel reserve.

    The RN & the Spanish, Italian, & Indian navies have coped.

    They all operate Harriers. There’s no such thing as a bolter or a waveoff with a Harrier. But with arrested landings, it’s not uncommon for pilots to fail to get aboard multiple times and need to hit a tanker.

    Already there is one key strike against Chinese carrier operations and that is not having organic tanker support.

    This means that if the PLAN chooses to conduct true blue water operations any aircraft with a problem will be forced to land on the carrier or land in the water. For without carrier based tanker support there will not be the safety net of a land divert field. It will be interesting to see how China handles situations like that.

    If they are serious about high-tempo carrier ops they will have to use buddy tanking like the USN does — the USN hasn’t had a true tanker on CVNs since the KA-6Ds were retired. I know buddy tanking has been done on Flankers before, but I don’t know how much offload capacity a Flanker can carry when it is launching from a STOBAR deck.

    … the one pic I have shows clearly an export F-15C single-seater but also clearly with the antennas outfit in both tailbooms like the F-15E who stood by.

    There really are not separate assembly lines for the single and 2 seaters; the aircraft are built in sections and assembled on the same line. The tooling is different for single seat and 2-seat sections. The specific avionics systems aren’t really a structural difference.

    I also seem to remember me having read, that the 5 israeli F-15D-50-MC produce in the same time frame were delivered almost with F-15E standard.

    Yes, like I said above, the 3 F-15D-50-MC sold to Saudi Arabia were structurally like F-15Es but with -D systems for the most part.

    Another question … do anyone now if all these 9 F-15C are still in aktive use … some source claimed No. 1327 to be lost, but in the description of the incident stood that it was an midair collision between two F-15Ds and that there would be 2x 2 people involved.

    Both F-15C 90-0267 / 1327 and F-15D 90-0272 / 1332 were with RSAF 13th Squadron and were written off Jul 2, 1996 due to the same incident. Most likely the accident report you read was mistaken.

    I’m curious how these aircraft looks in the cockpit or what radar they have. Have these specially built last F-15C, the same cockpit layout as in the front cockpit of the F-15E, and the same APG-70 radar as the last US F-15Cs, since both the cockpit and the APG-63 radar at this time were no longer in production.

    The F-15C block 49/50s were the same as the previous Saudi F-15Cs, but with APG-70s. Structurally, they were standard F-15Cs.

    The F-15D-50-MC aircraft sold to Saudi Arabia in the same package were structurally F-15Es and had the APG-70, but were otherwise equipped like the F-15Ds the Saudis received in the 80s. The main difference between these and the standard Ds were the structural reinforcement and the common engine bay.

    As far as the radar, all F-15C and Es built after 1986 were equipped with APG-70s, including some for the USAF. In USAF service, the F-15Cs delivered with APG-70s were the first to be refitted with APG-63(V)1, and their APG-70s were used as spares for the F-15E fleet.

    It was a strategic error to believe that the west would allow Iraq to threaten or control so much of the world´s crude oil reserves. Iraq totally ignored the end of the Cold War. … Just 3 years later the forces which could have been deployed would have been smaller.

    This is an excellent point. Regardless of “Israeli standards” or not, the U.S. sent its “tip of the spear” units from Germany to Saudi Arabia. Units like the U.S. Army VII Corps and the 36th TFW from Bitburg, that were trained and equipped to fight and win while outnumbered more than three to one. By 1994 none of these units existed.

    Nobody did water landings routinely with S-61s, and very few forces even practiced it (I believe the Canadians do). The U.S. Coast Guard operates the S-61R (HH-3F) and they do water landings, but that is a larger aircraft and even so the practice is pretty rare. It is safer and quicker to use a winch than to land on water for conducting rescues.

    The most succinct way to phrase it is that without American industrial support in WWII, western Europe would all be speaking German today; and without American military support in WWII, western Europe would all be speaking Russian.
