    How can the answer to this question be anything other than the Su-27?? I mean, later fighters are what we would have done in the 60’s if we knew better. If we have to use 1960’s technology, stick J-79 engines and an APQ-120 in it.

    The F-14 also had to face hanger deck clearance issues. One tall tail wouldn’t fit.
    I don’t suppose it would make a huge difference, but from the side of a twin tailed fighter, one tail masks the other, so it reduces the visual and radar signature that way too. One of the tails will mask the jet pipes from some angles, lowering the IR signature. I don’t think thats why they did it, but its a nice side effect.
    Two tails provides some redundency for surviving battle damage. There are two rudders, so you can lose one and still have one left. Again, its not going to make a big difference, but its a plus.

    My copy of US Navy F-14 Tomcat Units of Operation Iraqi Freedom says 470 mph. I wondered about it too.

    Most kits have wings that move. The most accurate kit, from Hasegawa, does not. I think the reason is that when the wings are forward, balloons on top of the fuselage expand to fill the gap at the trailing root. The kit has different balloon parts for each position. Other kits with swing wings can’t correctly show the wings in the 20 degree sweep position. The gap won’t go away.

    The engines seem close to me. I can even make out the clipped wingtips. Its an F-15.

    Fuel tanks get punched off all the time in combat. The F-105 also got rid of the pylon/tank as a unit.

    Really? Wing, centerline, or both? Are there any other aircraft that do/did that? I’ve never seen an empty F-106 wing pylon.

    Read about that. Impounded by BATF as it still had a functional 23mm cannon!

    Thats disgusting!!! 😡 Not that I don’t think he has a right to his gun, but the BATF could have just taken the damn cannon out and impounded that.

    The F-22 is better looking , the F-35 looks strange however i still smile everytime i think what could have been the Joint strike fighter had boeing been chosen:o

    😮 Oh what an hideous looking bird the X-32 was! I think I would rather we lost the next war than win it with the F-32. The F-35 looks ok, but the F-22A is pretty. I thought the YF-23A was cooler looking, but the F-22A is much improved over the YF-22A. The YF-22A tails were too big.

    The F-15 has a TWR as high as the Su-27`s TWR
    This would had allowed to the F-15 a good carring capacity, it is true it would had added weight as it would had been navalized, but it would had also take off with the aid of a catapult, the F-14A has a very low TWR and a very slow rate of climb, the F-15N would had been more like a Su-33 in that sense since the land F-15 has a TWR of 1.2 at normal take off, contrary to the F-14A that has really a very low TWR even worst than the MiG-23MF in fact it only has a 1:0.9 TWR empty, fully loaded, it gets as bad as 1:0.5, so the F-14 is a really overweight and obese aircraft even compare to the F-15.

    The F-14 is bigger than the F-15. The F-15’s T/W advantage is not going to keep it in the air with the same big load after it clears the end of the deck on launch. You could put all six Phoenix on it, but it wouldn’t have the same range.

    The F-15 has a better wing loading than the F-14A while the F-14A has a pancake fuselage generated lift, it also has a smaller wing, and it is heavier, also the Wing Pivots limit the G overload permitted and the F-14 was even limited to 6.5Gs due to the complexity and fragility associated with swing wings

    You should say, while the F-14 has a smaller wing, with its pancake fuselage it can generate more lift per pound than the F-15. Its not really true to say that the F-15 has a lower wing loading, except in the most literal sense. The F-14 is not G limited in combat, either. (Lets see, which plane has broken in half in flight… 😀 )

    F-14 Phoenix realities The F-14 can not land on the deck of an aircraft carrier with a load of six AIM-54 and it is restricted to a Max G load factor of 6Gs while carrying the AIM-54, so the F-14 armed with AIM-54 is not agile in fact is so limited that in agility it would be comparable to the MiG-31.

    Not quite that bad, but true, the Phoenix is not for dogfighting. But it would have a tough time pulling 6Gs anyway with all of that Phoenix weight, so a 6G limit is no problem at all. Besides, why would a pilot want to pull more than 6G with a load of AIM-54? The only manuver you would need to make is a 45 degree pull up to lob the Phoenix at a Backfire.
    If an F-14 can’t bring back six AIM-54, an F-15N never would have.

    So i do not think the Naval F-15 would had been worst than the F-14, in fact i think it would had been better why? The F-14 empty weight is 18 tonns, the weight of the F-15N would had been less than 14tonns, the reality the VG wing imposes a weight penalty that is even noticeable just looking at the empty weight of the F-15A and the F-14A, the F-15A is 5 tonns lighter than the F-14A;)

    The Navy chose a heavy VG aircraft because it will have the range and payload capability that a fixed wing Mach 2 fighter (or some slower Boeing pig) would not have, as well as other advantages. The F-14 and the F-15 are each beautifully optimized for their roles. Neither could perform the role of the other as well, which is why both were built. (Although the F-14A really deserved a better engine.)

    So then why the F-15 never was purchased by the US navy? simply politics and enough money to burn, simply like that, Grumman needed the program, the US Navy could not back down since the future of Grumman was at stake and the US Government would had been resposible for Grumman`s bankarupcy.

    Like when it went for the F-18E/F.

    The F-14A is inferior to the F-15A simply because as a whole the F-14 has two aspects that makes it more primitive than the F-15, one is older and less advanced engines and the other is weight penalty due to the VG wing

    As an airframe, I would say the F-14 is more advanced. It has several innovative tricks, like the pancake, the retractable vanes, and of course the automatic variable sweep wings. The F-15 doesn’t even have leading edge flaps. As a fighter, the F-15 is superior for the reasons that you stated. But the F-14 is superior in the fleet defense role.

    The question if the proposed Super Tomcat could be a better aircraft is an academic one for dreamers. It never was at a stage that came even close to a proposal, it was a simple attempt by Grumman to prolong an outlived design. Although the F-18E/F is heavy, it is still lighter than anything based on the F-14, consumes less carrier space, less fuel, is more flexible. It probably lacks the top speed and sexiness, but that’s about it.

    Perhaps we should resurect the F-8. It is still lighter than anything based on the F-14, or F-18A, consumes less carrier space, less fuel, and is more flexible. Its faster too. But really, to get the range capability of the F-14D with the F-18E/F, you would have to fill up the deck with tankers, and there goes the small size and fuel advantages.

    The F-18E/F brings more capability by having more sorties available per day. If the F-18 needs 20 man hours maintenance and the F-14 needs 40 man hours, you have 100% more sorties per day assuming that maintenance limits your sortie rate (which in a high sortie environment can happen easily).

    The F-14 had a very good mission availability rate in the Gulf War. I am sure it took more man hours to do that, which costs more, but it did fine.

    Overall, the replacement of the F-14 was overdue.

    Overdue for replacement by the NATF. The F-18E was overdue for replacement before its first flight.

    It is remarkable that the defense of the US carriers was based on an aircraft that was considered an interim solution by its makers.

    The F-14A was far better than an F-4. The F-14A was only an interim solution until the F-14B was to be built.

    F-15N

    Notice the early small speed brake and the unclipped wingtips.

    I wonder if Grumman ever proposed a fixed wing F-14 variant so a direct comparison could be made showing the weight penalty of the VG wing?

    The fixed wing Grumman VFX design 303F was one of eight final design configurations. I have no figures related to it, sorry.

    I have made a point and I stick to it. American enemies won’t get involved in a major conventional conflict with the US anytime soon. Alone the size of US conventional force even without Raptors is enough reason to go for asymetric warfare and all adversaries will continue to do so.

    We should endeavor to maintain that situation. Should we wait until our advarsaries are flying fighters that are superior to the F-15 before we start buiding the F-22? The Su-27 is already a match.

    The wise ones wouldn’t even drag their fighters out of the shelters, why bother with defense?

    I doubt anyone is going to leave their Flankers in their shelters.

    It might be your wet dream to see bearded guys trembling at the sight of F-22,

    I am more worried about asian guys.

    but it won’t happen, sorry… It can easily penetrate enemy’s airspace but it is unable to do anything meaningful there after doing so..

    How about protecting our strike force? How about shooting down their airforce?

    I have to agree with Jon James here. Just because we are fighting an insurgency, that’s no reason to abandon preparation for future conventional conflicts. Iraq is not going to be the last war we have to fight.

    I think a new F/C-17A would have much more time on station.

    Now how the hell is someone supposed to paint a model of that Slovakian MiG-29 now??? 🙁 Its about as impossible as the old Viggen splinter scheme! It does look cool though…
