I doubt it ever fought an F-4 in anything other than training, but against the Mig-21 and other types the Mirage III made many Israeli aces in the 60s and 70s.

(Image removed from quote.)

I count 13 Egyptian kills on that one.

I suspect the Israeli's much better training, proficiency, and well maintained aircraft had a lot to do with it.  It would be interesting to see a nose to nose comparison with equally trained and proficient pilots, and maintained aircraft. 

On an exercise deployment to Cairo West Air Base in the F-4, I had opportunity to fly a combined four ship low level and dry ground attack with the Egyptian Wing Commander.  I graciously and stubbornly agreed to him leading the four ship.  Low level was normally flown at 480 knots in the F-4.  As we followed in a tactical formation the airspeed was anywhere from 250 to 540 knots.  There was never a stabilized airspeed during the 200+ mile low level, not to mention altitude deviations.  There was a whole list of others less glaring debriefable items but, you get the picture.  We also had opportunity to examine the Egyptian Rhinos.  They were in horrible condition, sand blasted from being in the elements, didn't have engine inlet and exhaust covers installed while parked, etc.

Later, at home, a tasker came to send to crews to Cairo West to ferry two Egyptian F-4s to Hill AFB, Utah for PDM.  A couple of our younger crews jumped on the opportunity for all that XC time.  They're first stop out of Cairo was Torrejon, Spain.  Both jets landed with multiple red X write ups (groundable maintenance issues) and were stuck there for two weeks waiting for parts to arrive.  They finally arrive at Hill nearly a month later.  PDM personnel told our guys they hated seeing Egyptian F-4s show up because of the incredibly poor maintenance or lack there of.  Apparently, it was typical for the Egyptian jets to have upwards of 2,000 pounds of sand in the bottom of the engine bays. 

Months later, another tasker came down to ferry two more F-4s from Cairo to Hill.  Our same two crews jumped on the opportunity.  They had the same first stop at Torrejon, multiple red Xs, and were stuck there for a full months because of the severity of maintenance issues.  When our guys finally got home, we asked what that did for a whole month in Torrejon.  They just grinned.

Was it ever flight tested against the F-4, F-106, Mig-21, or other similar wing configuration?
The IAF considered the Mirage as the better fighter. The F4s did very well in A2A against mig 21s flown by Syrians, Egyptians and Russians, with gun kills taking a very significant fraction of the kills (about half iirc).
Last F4 kill in the IAF was in 1982 over Lebanon. It managed to steal a kill from under the noses of F15s that were supposed to be escorting it - the pilot spotted lower migs and broke formation without alerting the F15s in order to beat them to the enemy.

The Mirage IIIc is my second historical favorite after the mosquito (also served in the IAF). Their graceful arrowhead silluetes filled the skies of my childhood (converted to Kfirs by that time). All old IAF pilots that I talked to or heard speaking of it liked the Mirage III better than any other fighter they flew.

Have you talked with a pilot who had flown both the Mirage and the F-4?  It would be interesting to hear that perspective.  I flew both the F-4 and the F-106.  Curious about the Mirage comparison in relation to the Six and the Rhino.  :salute

Not surprising. While flying the F-106 against F-15s we routinely came from deep Six with our radar in standby and popped F-15s with heatseekers.  They rarely, if ever, belly checked.

The USN and USMC flew the Kfir (F-21A) as aggressors. There must be some data available on how they compared to Navy and Marine fighters in the 1980s.

Puma, was the pK of the Sparrow, and even Aim9, greatly affected by the ROE during LBJ and pre Nixon and Linebacker2/etc?  I also read recently that the F4U had some of the first NCTR capabilities of the USAF, and could detect the Mig21s IFF and other leaking signals and determine if it was an enemy aircraft or not - long before the whole counting of turbine blades and other Star Trek like NCTR stuff.  One of the military dailies I read recently did this article - http://www.wearethemighty.com/articles/what-made-the-f-4-phantom-ii-the-deadliest-fighter-to-fly-over-vietnam

I read all of Mark Berents books a few times growing up, and as much other F4 Phantom stuff I could find, I can't believe that this week is the first time I've ever heard about the no-ailerons deal with high AoA and using just rudder to roll.  How frequently would you be in such a high AoA position and do this, and at what point could you begin to use the aileron again?

Did you ever use the "pistol" centerline gun pod, even with the E model?  Just would like to know how much more accurate the internal gun was to that thing. 

Regarding the Mig21 vs F4 deal, much of what I've read, even from xSoviet pilots who supposedly flew vs the Phantom in the 21, was that in the vertical and E fighting at certain altitudes, the F4 had a pretty large advantage vs the Mig21, so it wasn't all Mig21 all the time, both had advantages and disadvantages IMO.  Also the F4 had another set of eyes and another brain on board, that's a huge plus.  The Mig21 also was pretty limited compared to the F4 in terms of range, payload, a2g capability, radar, and many other things.  The Mig21 was and still is a great fighter for its cost and purpose though, some of the newer ones that have been upgraded by the Israelis are still pretty potent little fighters, with the newer Archer missiles and HMS, better radar, systems, etc. 

Puma = one thing about the F106 I always wanted to ask, is how to you decide which side of the front cockpit to look out of, with the strut being right through 12 oclock in your front view?  Is it dominant eye, or are there avionics or a HUD set up for one side or the other being optimal?

Now the flight video simply said to keep the turns coordinated.  It didn't say not to use ailerons. 

One trick the F-4 had to turn inside a Mig-21 was to yaw the aicraft at a high angle of attack and temporarily depart it.  When done right, the nose would slew ahead of the mig and then the F-4 would be in the advantageous position.  This maneuver was taught at Top Gun and is covered in about 3 different books.

Great questions and discussion, Gman.

One of the huge problems during my active duty time was ROE.  We had some pretty decent BVR missiles but, in order to prevent fratricide, we were restrained to make a VID before shooting, which would often force a turning fight, thus preventing the use of the Sparrow.  This, in turn, would require use of a heater.  The ones we had at the time were constrained to an aft shot.  Follow on versions greatly expanded the lethal envelope.  So, with all of this in mind, a gun was the answer and sometimes the only real option once we got in the phone booth with a better turning opponent.

Using the rudder was essential in the hard wing jets or else, as described earlier.  When I got into the E in Korea, it took some time to unlearn the no aileron mantra and take advantage of it during trips into the phone booth.  I grew up in flying using rudders all the time.  In those high AOA arenas, I tended to use a lot of rudder to get it started and use aileron to sweeten the turn as necessary. Pretty much a balancing act.  Hard to say exactly when to and not to use it.  It was more of a seat of the pants thing once I got somewhat proficient in the jet.

In the F-4 school house I flew the D model.  On some of the range rides I got to strafe with the centerline pod.  It had to be boresighted perfectly to be effective.  To the best of my knowledge, it wasn't used on the E model.  Now, would I have liked to have the centerline gun on the E?  You betcha!  Talk about a gun fighter! Somewhere, I saw a picture of a D with three gun pods mounted.   Arrrggghhhh, what a beast that would be.

During our deployment to Cairo West AB, we flew a sortie against the Egyptian Mig-21s.  In the hazy sand filled skies, the Migs where virtually impossible to see when they were pointed straight at us.  All of the Vietnam vets I was privileged to fly with and against, said not to get in a turning fight with the  Mig-21.  The desirable tactic was to keep the airspeed up, maintain energy, and shoot at long range.....outside the phone booth.

In the Six, the strut was really a non player.  It was not wide enough to be noticeable since it was on the centerline of the pilot's field of view.  From the exterior side view there is a black panel in the windscreen forward of the pilot.  This was a thin plate that prevented light glare from reflecting between the two slanted windscreens and creating a distraction, especially at night.  This was also a non issue since it was also directly on the centerline. Below, the black splitter plate is visible in front of the pilot.  "026" was my assigned jet when station with the 5th Fighter Interceptor Squadron at Minot AFB, ND.  Shown here at Davis Monthan AFB, AZ during a visit to our Air Defense Alert Detachment.



Here's a different view of the "splitter".

Puma, thanks for the answer, great stuff.

Question about the Aim4 Falcon missile since you brought up the heaters - was it really THAT bad?  I read that Robin Olds got so P/O'd at them that he flipped out, had the techs rewire his entire wing for Sidewinders instead, all without orders, and then even against orders, and procured Aim9s on his own, since the Aim4 on one flight he had went 0 for 8, with 2/3 of them not guiding or just going dumb.  Did they improve post Vietnam?  I know that the 106 had that Genie nuclear bomber formation buster, but did you have the Aim4 nuclear warhead missile as well, with that "small" .25kt warhead?  Heh, small, 250 tons of explosives in an A2A missile.  What kind of range would the ...not really a blast pattern, but I guess the shockwave/firestorm/whatever that an a2a nuke would have?  Not the range of the missile so much, but the range of its warhead.

How did the F106 fly compared to the F4 in your opinion, did you ever do dissimilar air combat training vs the F15 in the F4 as well?  The deep 6 surprise attacks aside, how did the 106 fare vs the F15 in a VID pass then fight sort of engagement, what were your best options to try and beat the F15 in something like that?

Thanks Gman. 

Yes the AIM-4s were that bad.  The Six had four, two radar guided and two IR guided.  We referred to them as "Hittiles" vs "Missiles" because they were designed to physically hit the target and activate the contact fuses (white strips) located rearward on the fins.  See the photo below.



The PK was so poor that they were fired in pairs off the Six. 

The Genie, on the other hand, had a fantastic PK.  The fire control computer in the Six set a timer that would allow for a safe escape distance for the pilot after launch.  At high altitude, the distance was greater than at low altitude.  At launch, the Genie accelerated near instantaneously to Mach 3 in addition to the Mach speed of the Six.  Most of the time, pilots would try to be around Mach 1.5 or more for launch.

The Eagle was quantum leaps above the F-4 in performance.  Typically when fighting them, the ROE would be heaters and guns with no turns until crossing the other guy's 3/9 line.  It was tough to get the advantage on an Eagle driver, unless he made a big mistake. 

The F-106 could make one good bat turn and then it was nose down in full AB to regain speed. 
Again, if the Eagle driver made a mistake a good Six pilot could get a shot.  Occasionally, Eagle guys that didn't know about the Genie, would brief all up weapons and all aspect.  We would of course launch the Genies on a wall of Eagles and call kill shots.  The next time it would be heaters and guns.  The Eagles had better radar and IR missiles.  So, we had to get creative and present them with the unexpected whenever possible.

Again, "Hamburger is hamburger, no matter what you wrap it in".

(Image removed from quote.)
The Kfir was made with A2G in mind. The more powerful american engine was largely offset by the increase in total weight in comparison to the Mirage IIIc. My guess is that turning permormance suffered. By all accounts it was less pleasant to fly, but had much better A2G capabilities.
In the age of the early F15s and F16s in the IAF, the radar-less Kfir was already obsolete as a fighter.

Jack Broughton thought the Six would have been ideal for CAP/Escort in Vietnam.   Was he onto something?

He loved that jet.  I read RUPERT RED TWO not that long ago and he extolled the jet--though he lamented the heck out of the horrible ejection seat.

I think the F-4 would take the Mirage overall.   If I had to chose one or the other I would pick the F-4 any day.
