Hey guys, just talked to a friend of mine, a former Navy pilot, regarding this and he said that the F-14 turns better than all the rest hands down, being able to sustain 8.5G's until fuel runs out, while the others, including the F-15, can maintain 8G's. Furthermore he mentioned that the variable sweep wing gives it excellent manuverability for an aircraft so large and heavy, esp. in the horizontal, permitting this interceptor to also dogfight against the lighter USAAF fighters.

Furthermore the F-14 uses a lift-body design, giving it even greater lift in turns. He also said that the F-14 has been successfully outmanuvering smaller and lighter adversaries all through it's service life despite the fact that often it is nearly twice as heavy.

Part of the secret is the computer controlled variable geometry wings which automatically adjust for all flight aspects. This is a great help as it makes sure that drag is as low as possible when needed and lift is as high as possible when needed.

Another secret he told is its low wing loading for its size. Like the F-16, F-15, and many of the newer MiG and Sukoi types the F-14 obtains a sizable fraction of its lift from the design of the fuselage (The lift body design), keeping "wing loading" low.

According to him the F-15 climbs better though, but the F-14 will climb with an F-16 and out-accellerate most fighters in level flight.
Don't know who your buddy is or what squadron he was in, I could tell you the F-15 is a 9G airplane, read "F-15 Eagle engaged" By Steve Davies Page 82. Additionally the -1s show configurations where the F-15 could sustain 9gs. The F-14 has a higher wing loading and lower thrust to weight ratio than the F-15, go to any web site (Wiki) and it will show that. It was an "excellent" machine with "excellent" maneuverability - the F-15 is just more maneuverable.


The F-14 "was" a great aircraft and is still worthy of front line operation but as stated the F-15 is at least a half a generation a ahead of the F-14, especially comparing it to the later block "C" models.

Permitting versus winning are different concepts

Against Libyan pilots he is correct. Against the A-4 when he can use better much better T/W to maintain energy and fight in vertical, he is correct

The F-15 climbs better though.

Soren - it does not do well in Red Flag exercises. In fact, it has not for 20 years. The USN quit sending F-14s to play with USAF as the F-18 started getting to the fleet. There was a reason for that - and it wasn't superiority of F-14 as a dogfighter.

The WL of the F-15 is about the same as the A-4 and the A-4 generally whipped F-14 ass in subsonic turn where the F-14 variable geometry actually helped it (other than take off and landing).

The F-14 is slower at both altitude and the deck, has a lower ceiling, has a T/W ratio that is 25% less than the F-15C and 25% less than the F-16. The F-14 has a T/W fully loaded at about .6 where the F-15C is .85, and a combat T/W of .9 to the F-15 1.15. Usually those deficiencies will hurt you in both the horizontal and the vertical.

If not then a B-26 should easily whip a 109 in both the vertical and horizontal.

The only thing the F-14 can do better is see a threat earlier with its bigger and better radar...and land on a carrier.

BTW the published wing loading for the F-14 is approximately 50% higher than either the A-4 or F-15C. The straklets gave improved flow into the wing and engine inlets but it is insignificant relative to energy manueverability - except very possibly near the stall.

As to G capability both the -15 and -16 airframe capability exceeds the pilots capability... both > 9G.

Just out of curiosity, how long has your friend been out of the Navy and when was the last time he took on an F-15C in exercises?
 
He says the F-14 capable of sustaining 8.5G's until fuel runs out, although this isn't recommended and the airframe would have to undergo inspection afterwards. The F-15 can probably pull more G's for s shorter period of time, I don't doubt that, but according to him it can't indefinitely sustain as high a G-force as the F-14. He said that at 350 knots the F-14 can pull 8.5 Gs while the Mig29, F-16, F-15 and F-18 can only pull about 8 Gs at the same speed.

From the early eightees until the early ninetees IIRC.
 
"The F-14A Tomcat was powered by two massive TF30-414A Afterburning Turbofans with over 40,000 lb Total Thrust. While the engines were quite powerful for their time, the F-14 was still considered underpowered. And it is due to this very power-plant, that the F-14 was considered a poor dogfighter. The reason being that whenever the AoA of the aircraft changed rapidly, the engine would go into a compressor stall - a state where the engine stops the intake of air and flames out. This problem can be seen when the F-14s go out for DACT. None of the Tomcats carry AIM-54 and ACMI pods are limited to inner rails only.

The problem was later corrected in the F-14B and subsequent models, by the use of two F110-GE400 Afterburning Turbofans with over 54,000 lb Total Thrust. These engines not only gave the F-14 the excess power, but also made it a potent dogfighter."

Even re-engined the F-15 still puts out more power than the F-14B.

True, but the F-14's wings are more lift efficient, creating more lift pr. area when folded out. The span-loading, which is a good indicator of turn performance according to some as an a/c rides on a cylindrical tube of air, suggests that the F-14 is the best.
 
Again I'll state - I was on a RIMPAC excersize and was told the AF F-15 knocked down F-14s at the rate of 3 to 1. This is with the Navy attempting to overwhelm the F-15 with superior numbers.

Not compared to an F-15 when its putting out almost 5000 pounds more thrust. Again an F-14 can not out turn an F-15, especially the earlier F-14As. And I'd like you to show HOW the F-14 carries a more efficient wing?

That is also the reason the -15 is still being produced, 35 years after it's first flight, and the F-14 is not; the F-15 was designed FROM THE OUTSET to be more maneuverable than any other a/c on the planet and, to this day, it is STILL more maneuverable than 90% of the fighters out there (including some 5th-gen fighters, especially with the 29,000+ lbs. PW-100-229 engines).

And, as drgondog pointed out, the maximum g-loading for either a/c is rather academic anyway, as the pilot can only tolerate a few seconds of 9G+ maneuvering; the a/c definitely is more "capable" than the pilot in this case.

Well how can you state that as fact, do you really know it to be true ?

And I'd like you to show HOW the F-14 carries a more efficient wing?

Easy, the F-14's wing can change sweep and is of a much higher Aspect ratio, and a higher aspect ratio means a higher CLmax lower Cdi, making it a more efficient wing FLYBOYJ.
 
Like I said earlier span-loading is a good indicator of turn performance according to some as an a/c basically rides on a cylindrical tube of air, so lets look at the span loading of the a/c.

Span loading of the a/c:

F-14: 27,700 kg / 19.55 m = 1,416.87 kg/m
F-15: 20,200 kg / 13.05 m = 1,547.89 kg/m
F-16: 12,000 kg / 9.8 m = 1,224.48 kg/m
F-18: 21,320 kg / 13.62 m = 1,565.34 kg/m

Seems the F-16 beats the pack but the F-14 comes in as second.

Why don't you look in the POH of each aircraft and it will tell you the exact data you are looking for.

Hmmm, I rather have 2 F16's for the price of one F15 or 1 F14......

And for some operators that was the reason why the F-16 was chosen over the F-15.



"Even today, the F-14A Tomcat is still a potent fighter. Against aircraft such as the F-4 or the MiG-23 "Flogger" the F-14A would have few problems in maintaining air-to-air superiority, but its rate and radius of turn, thrust-to-weight ratio, and high-angle of attack capabilities would leave it at a serious disadvantage against later aircraft such as the F-15, F-16, F/A-18, MiG-29 Fulcrum, or Su-27 Flanker. Nevertheless, its BVR kill capacity is still unmatched.

Service of F-14 Tomcat with US Navy

As stated, the F-14 is best viewed as a bomber killer with some "good" air-to-air capabilities but against the F-15 it is at a disadvantage.
 
Why do you quote facts about the F-14A FLYBOYJ ? The F-14B is vastly better in the horizontal than the F-14A, and also better than the F-15 according to most I've read and the people I've talked to.

Don't have it FLYBOYJ, and I doubt most people do ;)

Vastly better? Come on Soren, what's vastly better? If the F-14 was so much better why did the navy stop sending the aircraft to William Tell, RIMPAC and other exercises even AFTER they were re-gngined? I was at a RIMPAC exercise as a participant and was told the -14s got its @ss kicked by Navy people!!!!! and fighting in the horizontal is something done 60 years ago. If you're fighting on the horizontal in a modern jet either you're a 3rd world fighter pilot with minimum training or you really screwed up - and who have you really spoken to? One Tomcat driver who flew in the 80s and probably never got to fly an F-14B? Look at the stats on the airplanes, the F-15 still puts out more thrust, has a lower wing loading and a higher thrust to weight ratio. It was designed as a fighter from the ground up and was on the drawing board when the first F-14s was being delivered.

As far as the manuals? Look on E bay, they're on there - I have access to an F-15 manual but I can't scan or copy it.

"The overall thrust-to-weight ratio at maximum load is around 0.56 to 1, which does not compare favorably with the F-15A's ratio of 0.85 to 1."

From Wiki - Thrust/weight: 0.91 THIS IS FOR THE F-14 "D"
 
It was designed as a fighter from the ground up and was on the drawing board when the first F-14s was being delivered.

It all comes down to what each a/c was designed for: the F-14 was designed FROM THE OUTSET with Fleet Defense in mind, which means shooting down bombers, and other less maneuverable attack a/c, attempting to destroy US Naval assets. I believe the primary adversary the F-14 was originally designed to counter were Tu-16's Tu-22/M/26 missle bombers, which were medium-sized tactical bombers for use primarily against the US Navy, especially large surface targets, like aircraft carriers. There was no need to make the F-14 very maneuverable, as they would be flying against much less maneuverable Soviet bombers.

The F-15, on the other hand, was designed from the get-go to acheive maintain air superiority against any current and future Soviet fighter. Therefore, it was designed with exceptionally low wing-loading, and exceptionally high excess thrust (especially for the '70's).
