    Drag is another issue. When the engine/s is inside the body the whole airframe can be more streamlined.

    Kinda reminds me of the FW-190 from thins angle

    It was published in the past the the Rafale can land and take off from US carriers.
    However, maintenance, ACLS, etc. are can be a problem.

    Where is the IRST on this variant?

    In its upgraded LANTIRN system called Tiger Eyes, which also ontains a CCD.

    Thanks for the informative post Distiller
    As both me and arthur stated, to say a plane (or equipment) is draggy requires something to compare it by. Are you comparing it with the F-14, or …?

    I still stand by my point about the pylons- the fact that the navy uses them all the time doesnt really matter. Its like saying the Tomcat is draggy because it carries (used to carry, but lets dont get technical) the big and heavy AIM-54.
    If you want to go into weapons & equipment, than Ill bet the LANTIRN carriage method on the Cat (where it is hung like a seperate weapon) doesnt help reducing drag.

    The tomcat’s nosemounted IR/TV/ECM pods and thick wing (that houses the variable wing and its controls) however, are an integral part of the machine, and cannot be separated from it.
    I’m also sure the F-18A-D round intakes cause less drag than those of the Tomcat.

    I’m very disappointed to see such a comment from you Arthur, as one of the most respectful and knowledgeable members here.

    The Tomcat is also a much larger and heavier airframe with a far larger frontal area, so just giving a speed/thrust ratio to suggest the F-14 is draggier is nonsense. Of course it is – because it is a lot bigger.

    Well, what else where you thinking of taking for drag comparison if not frontal area?

    As for those inverted double-kinked bathtubs hanging under the wings of both vanilla and sewer Hornets: yeah, they are draggy as hell, and heavy too. The Swiss refused to buy those SUU-63 pylons for that very reason, and instead opted for a far lighter, less draggier pylon. The original Hornet bathtub was designed for the Hornet to have it carry TER and (not sure about the latter) MER bomb racks because it was purchased as an A-7 replacement in the USN. Of course, MER and TER bomb racks aren’t used anymore, now with PGMs you can hit a target anyway and the combination of bathtub + TER/MER created so much drag that the range of a loaded F/A-18 became really, really pathetic.

    Again, diverting from the subject. Are we discussing the hornet’s drag here or its weapons? As you said “for the same token” one can state that the Tomcat has very limited ability because Iran lacks replacement parts for it.
    The information you gave about the Swiss substitue only proves that this is only true to the ones who uses these pylons, and has nothing to do with the plane itself or its capabilites.
    Also, you comfortably failed to mention that these Swiss pylons only has A-A carrying ability, and no A-G what so ever.
    Also, the linked article states that the Swiss pylons are less draggy than the American ones, but doesnt say if the SUU-63 are very draggy all-around. My guess? – If they really were so draggy, the USN would have replaced them with something better.
    But again- this whole area has nothing to do with this thread.

    . By the same token, a Tu-160 is a lot draggier than an A-7: see you’re talking nonsense, ohadbx?

    If you want to go to unrelated areas than yes, the Tu-160 is much draggier than the A-7. But what these two planes have to do with eacother, or this thread- you are the only one to know.
    I did’nt invent this Cat Vs. Hornet battle and comparison wars, just simply answeredthe guy’s question. Fact is, that most Hornet bashers rely mostly on hearsay and prejudices (“both vanilla and sewer Hornets” is one example), rather than hard facts.
    I’m sad to see that non of the information you presented in your messege has something to do with mine, or this thread in general.

    Well, the funny thing is (for me at least) that this comment is almost always made by Tomcat fans.
    The thing is, that considering they have roughly similar size (similar height and lenght, wingspan depends on the Tomcat’s position) I would say that the Cat is MORE draggy than the hornet.
    Why? because the hornet achieves a maximus speed of 1.8 Mach, by using 2X18,0000 lbs engines (C model), while the Tomcats has a slightly faster M1.88 top speed, but using a whoping 2X27,000 lbs engines (B model).

    So, who is draggy now?
    You can claim about any aircraft that is draggy, but compared to WHAT?

    what was the fly away for the SUFA

    Est. 40mil USD for the basic block 50+ configuration (according to the official IDF/AF magazine), add a few millions for the Israeli systems.
    Same source claims 55 million USD for block 60 aircraft for UAE.
    If you take 4.5 billion USD (total purchase cost) and divide it by 102 (number of airframes) you get 44 mil USD per unit. Not sure if this sum includs the Israeli systems, which may be bought for the Israeli companies and not be included in the 4.5bil cost, all of which from american aid.

    Note that Israel’s current fleet of Block 40 aircraft share many things (including armament,capabilities and technical related equipment) with the F-16I, which are bound to get the introduction and operating costs down, while the closest the UAE has is the Mirage 2000, which is not very similar.

    It seems really strange to me that all of you neglect connected equipment and services in your calculations.
    F/A-22 is stealth, has internal bays, can supercruise (at ~M 1.7 compared with M1.1 of the eurocanard), has TVC and AESA radar TODAY- not in some future possible Tranche, that may be cancelled or changed due to politics or other reasons.
    All these charactrasitcs cost money to build and MAINTAIN. The Typhhon is much closer to modern fighters (for example F-15E and perhaps Tornado) than the raptor, so it is expectable that the introduction cosots of special equipment and perssonal training will be higher for the Raptor.

    About the simulations- even if the DERA sims were somehow accurate (though I dont see how can they have access to classified information about these planes) – it is still wrong to assume 2 Typhoons=1 Raptor.
    Why? because when you have stealh I dont see how an airborne Doppler radar can detect you (not even a strong ground- or AWACS- based phased radar).
    Also, note that they did F/A-22 Vs SU-35 and Typhoon VS Su-35, NOT F/A-22 Vs Typhoon. Gee, I wonder why… could it be because DERA belongs to the UK MoD? noooo…..
    Not to mention that these sim-test-pilots dont have access to specific tactics developed for these planes, only assumptions.

    Take care 🙂

    I thought the whole point behind retiring the F-4 was to focus on only 2 fighter types…
    I really dont see them buying any new fighter aircraft in the near future, and the F-15/F-2 retirement from JSDF is very far ahead.

    And another important part to highlight is: “Lockheed-Martin plans to install the conformal fuel tanks on the latest versions of the F-16, Block 50/52 and Block 60, that are in production for the USAF and other air forces, including the Israel Air Force.

    The USAF doesnt plan to buy the Block 60, they will have the JSF. So that leaves UAE as the only Blk 60 operator today.

    In my opinion they were all good enough to mention, every tactic for itself.

    Israeli “Wild West” engagements with the Egyptians.
    Operation Moked (The air strike at the beginning of the 6 day war).
    Israeli strike on Syrian SAMs in 1982 (using UAVs as deception)

    (Yeah, I know all these have something obvious in common, but this is what I can come up with right now)

    Well Galdri, the Javeling is one of them. At the time I understood that these mini-jets are a trend in future aviation, rather than specific project.
