Very nice description of GE, and their very successful engines. I feel lucky to have worked on the LM1500, J79, J47, as well as the RR Avon. Got test run footage of all of them posted!
I grew up in Venezuela in the mid-Sixties, and flew VIASA Convair 880s to Miami probably 20 times. The engines were unforgettably loud and smoky outside the aircraft, but thanks to extra thick skin and lush insulation, were barely audible inside the cabin, at least in the forward section. Great video, Mike!
The LM1500 was also used for power generation in industrial applications. I recall visiting a GE appliance factory in Ontario Ca (78-79?), on a field trip for an engineering class. Tucked into a corner of the facility was a repair/rebuild shop for those units. I was impressed with the intricacy of the variable stator mechanism and general design and fabrication of these magnificent engines. Such a contrast: on one side of the lot they are manufacturing home steam irons, on the other, working on 13000 hp engines. And on another GE related note, my family and I flew to our new lives in the US on an Aerolinias Peruanas 990, March 1964. Buenos Aires-Lima-Mexico City (TWA 707 to Los Angeles).
This is really fun for us, Mike, as my wife’s father worked as an attorney and sales guy for GE in Evandale, Lynn and Palmdale. And he worked for Allison before that. We got to attend the B1 rollout in Palmdale in 1975 at her father’s invitation. My own father was on the SST Advisory Committee with DOT.
I was a Plane Captain on the RA-5C Vigilante. I spent many hours around the J79 GE -10. Station in RVAH-6 and RVAH-12 in Key West and on the USS Nimitz and USS Saratoga.
Thanks, Mike. My friend's father in elementary school worked on that engine in Evandale. My friend brought to class pictures of the first 747s. The cabin spaces were so big it was hard for bunch of 2nd graders to wrap our heads around. Of course we followed planes so we knew.
Awesome video . all hail the GE engineers I had a job delivering frozen chickens in Goodyear Arizona to their testing plant where they would fire them into the engines at full throttle it was amazing to watch
The howl of the zipper, once heard one might not forget that sound. The marriage of that engine and airframe is amazing. Another great video. Excellent work as always.
The F4 Phantom was the most efficient converter of JP4 to black smoke. The F4 Phantom is still the world record holder of distributed Mig parts. I flew the F4 Phantom N, J, & S models from 1978 to 1981. The S model was produced in 1978 with several improvements, and the engine was improved and operated at a little higher temperature, which reduced the smoke considerably. The F4 could use a lot of fuel very quickly. When doing ACM air combat maneuvering looking outside fighting another airplane I would look back inside just to look at one gauge and that was the fuel gauge. The J79 engine was a marvelous performer and would run as long as it had fuel. I will always miss those days. Charles "Orville" Wright

We have a vigilante in our little neighborhood of DeBary , Florida . She crashed after takeoff From Sanford Naval Air Station when I was a kid in the’60 s Crew ejected - Now we are proud To have a F-15 Eagle on a nice stick at our park . Great to visit , not fancy , just nice .
Great video Mike. GE made excellent jet engines for some of the most outstanding aircraft ever produced. I was around several of them while serving in the USAF.
J79s sound good. Aviation Nation 2007 Heritage Flight video on UA-cam has a couple of E model (QF-4E painted in honor of Robin Olds) passes in full AB.
I will always remember the J79 by its use in the F-4. I was a kid, but my dad would take me to the base and I'd get a good site, smell, and thunderous sound of those J79's back in the day. He was stationed at MacDill AFB during the high days of Vietnam. There were F-4's from TAC lined up on the ramp for days. Good times.
J79‘s better known as “old, smoky“ are forever melded into my mind with the F4 Phantom. although I know they were used on the starfighter, the vigilante, and the hustler. Did not know they were used on two hydrofoil designs.
You expect military planes to be loud, but I reckon the loudest, subsonic, airliner, would have to have been the Convair CV-990. I remember seeing Swissair examples at Heathrow and Spantax ones at Birmingham in the '70's, and the noise was just unreal!
I remember the 990 based at NASA Amers Research Center. My building was next to the hanger where it was serviced. Along side was an U2, a Cobra, the XV22, and RSRA to name a few. The Us almost blew my VW over with its exhaust as I crossed the taxiway one morning. The XV22 did a little demo for my one lunch time as I went out on with my camera and took photos, the pilot stopped, hovered close to the ground and did a 360 right in front of me, then went on his way. Those days. We also had the Pacific P3 base on the Navy side, so constant action there too. The NASA 990 came to a sad end when it collided with a P3 on final approach, only one survivor who ended up paralyzed, Navy guy who fell from the stricken plane when the tail got cut off by the 990. Turns out both planes were cleared to land o the same runway. I wasnt working at Ames yet when that happened, but I saw the crash smoke from home, about ten miles away.
Mike Machat is the coolest dude on yt for anything aircraft-related. Dude's voice is honestly a form of sleep-hypnosis ngl. Jokes aside though, there are so many channels on yt that misinform viewers, Mike's always spot-on though!
Great episode, Mike - really cool material. My first introduction to fighter aircraft was watching a (Orenda J79-powered) CF-104 buzz our family farm on a cold winter's day c.1974. Unforgettable howl. Black smoke. Low level. Fast. Had it been camera-equipped, RCCE techs would've seen six young faces with eyes wide and mouths agape, our toboggans dropped where we stood.
Great video. Could you please do a short video on the cost of the xB-70 program, specifically the cost of the engines and what it would be in today's dollars? The numbers I came up with were unreal. I think your subscribers would be interested in this topic. Thank you for all the information you present on your channel.
12:24 The 2707-300 is the only image of the Boeing SST that I remember ever seeing back then. It turned out that people would not tolerate sonic booms over the CONUS and so there was no market for the SST in America.
The SAS 990s were leased from Swissair. They lasted only a couple of years with SAS. I remember reading a “farewell” article about the 990 in the SAS in-house magazine “Inside SAS” in 1966 or so.
Yeah Jeff, I've worked on the F-21A, Kfir, C-1's that we had from '87-89, in MCAS Yuma, at VMFT-401, with the HUGE : J-79's until March /April of '89 , when we transferred over to the F-5 E's. We've originally got them from the Air Force, and the Navy F-5's from "Top-gun". Years later , after flying the piss out of them , then we 've got SWISS F-5's,,, that's what we currently have.
That is a very nice video on one of aviations greatest engine masterpieces, thank you Mike. Perhaps another idea for a new episode might be the placement of engines on aircraft. For instance, the Heinkel 162 and Cirrus Vision Jet have the same engine layout in common.
As always, wonderful videos and so much information (and unique pictures!) in them. Always a treat to see your videos Mr. Machat! In Mexico we (apparently) came close to having a J79 equipped bird in our air force. Supposedly at some point during the late 70s Mexico was looking to purchase the IAI Kfir, but said move was blocked by the US, specifically because the US did not want Mexico to have the "high tech" J79 another contender in that purchasing round was selected, with Mexico procuring a similar number of F-5E/Fs. After seeing this video I can't help but continue to suspect the high tech nature of the J79 by the late 70s was not really the case anymore (20 years earlier, of course!) and it had some other reasons, but oh well, politics and dollars I know Mexico also entertained buying Mig-29s and SU-25s/27s at some point, but I'm sure that was just to -piss someone off- get someone's attention over at Washington (a once numerous fleet of Mi-8 hips not withstanding).
Excellent post as always Mr. Machat! Good history, great presentation as usual. Never knew about the non aviation use of the GE powerplant. Very interesting. Lots of great info as always, and I was surprised at the actaul progreesion of the engines. The nomenclature has always confused me, that is, until now. You make it much clearer, and I thank you for that. As always, God Bless you and your family. Thanks for everything you do! Merry Christmas to you and yours! Take Care Always Sir!!
Thanks for the video. Very informative. Quick pronunciation corrections on the Kfir… it’s pronounced K’fear (like beer, steer, or deer but with a very short Kh sound at the beginning, rather than Kh-fur). It literally means “lion cub” or “young lion”. The IAI subsidiary Bedek is pronounced BEH-deck (emphasis on the Beh).
I’d love if you could cover the GE-4 more in-depth! If memory serves correctly it’s the worlds most powerful after-burning turbojet! I’ve only seen one or two videos that even mentioned the GE-4 in passing, and one single video of the engine actually running.
The Douglas F4D Skyray AKA the "Ford" is mentioned 6:10 but not shown. In any case, it was powered by the Pratt and Whitney J57-P-8B turbo-jet with afterburner following the failure of the Westinghouse J-40.
Aircraft shown at 06:10 is the McDonnell F4H Phantom II, as opposed to the J57-powered Douglas F4D Skyray, Grumman F4F Wildcat, or Boeing F4B biplane fighter. All different Navy designations from different eras. Thanks for watching!
Thanks for the comment. In an earlier video on the Bell XP-59, I said "GE One-A engine" and was corrected by a General Electric engineer who said it was the letters "I" and "A" on that sign. Thanks for watching!
The J79 also was in the F-4 Phantom. Great engines but unless you were flying in minimum burner, the Vietnamese could spot them since they were, unfortunately, very smokey.
The J79 was a good engine, but GE had developed an all-new engine core of what became the F101 military turbofan, with the first application being the B-1 bomber. That same engine core became the basis of arguably the most popular high-bypass turbofan engine, the CFM56.
Outstanding video. Remarkable Power plant. They were pretty smokey. Trying to find out how much of the technology for the aircraft engines leaked over into the "frame" series gas turbine electrical units. I know GE provided gas turbines for the UP railroad for their high horsepower locomotives back on the 60's and early 70's. They were quite successful until bunker C fuel oil was priced out of range.
Love the painting of the Vigilante climbing up into the sky. The Revell box scale kit was one of my first aircraft kits as a kid and I absolutely loved the box art of the launch from the flight deck.
Hi Mike, You did'nt mention that GE was black balled by the Air Force for many years, after the loss of the XB-70. The Air force blamed GE for unnecessary loss of the Valkyrie ( and Joe Walker in an F-104) while doing a promo photo shoot for GE.
I remember those J79s being annoyingly smokey, loud and smelly. Precisely the three attributes that those wonderfully gorgeous paintings never had to convey, lol..
Another nice video Mike! I know aircraft and thier engines pretty well, but I learnt 2 new things on this one. Those aft fan versions of the J-79 are new to me. Were the fan blades built into the low speed turbine wheels or what? How was the hot turbine portion sealed from the cool fan section.......interesting. the 2nd was about the XB-70 motor. There is NO WAY an 18k thrust J-79 could reach 60k thrust. That is an entirely different and much bigger motor ....correct? I guess my favorite BEAST motor, the J75 is really only the biggest mass production U.S. pure turbojet. You didn't mention the variable pitch stator blades in the compressor stage. A defining characteristic of that engine...that plus how smokey they were. I think a VERY refined version of this motor....the LM2500 (or something like that) powers our navy destroyers and some FAC'S. Portable generating stations also. Loved your box art too!!!!
The XB-70 used the yj93 with a max thrust of about 30,000 lbs. The GE4 was developed for the SST and had a max thrust of about 60 - 65,000 lbs. The key technology that the three shared was the variable stator. Each engine was much larger than the previous.
@@kevinbaird9763thanks. I'd like to see a pic of the SST motor with a man standing next to it. Must have been massive....a pure turbojet- no bypass fan stage?
I never knew my GE clothes dryer had such pedigree
GE were making steam turbines, turbochargers and superchargers and thats why they got the whittle engine.
Mine sounds like it is ready to take off.
They like everything that spins fast.. Like a GAU-8 30mm gatling guns ! (yes they made that too)
Very nice description of GE, and their very successful engines. I feel lucky to have worked on the LM1500, J79, J47, as well as the RR Avon. Got test run footage of all of them posted!
The F-16 also flew with a J79 as a demonstrator for a possible lower cost/performance export model.
Yes! I forgot about that.
I grew up in Venezuela in the mid-Sixties, and flew VIASA Convair 880s to Miami probably 20 times. The engines were unforgettably loud and smoky outside the aircraft, but thanks to extra thick skin and lush insulation, were barely audible inside the cabin, at least in the forward section. Great video, Mike!
GE made excellent engines, and you have resumed very well its evolution! Keep up the excellent work, Mike! Greetings from Brazil! 🇧🇷

What a Bird Mike ! The RA5 Like the B-58, it just reeks of speed, from every angle.
Navy pilots liked the RA-5C, saying it flew like a fighter. 😎👍
Nothing like the sound of a B-58 with all 4 blowers going on takeoff. I was at 305th BW at Bunker Hill. I never got tired of watching them.
I was a Plane Captain on the RA-5C Vigilante. I spent many hours around the J79 GE -10. Station in RVAH-6 and RVAH-12 in Key West and on the USS Nimitz and USS Saratoga.
Used by some of the most iconic aircraft ever made.
Thanks, Mike. My friend's father in elementary school worked on that engine in Evandale. My friend brought to class pictures of the first 747s. The cabin spaces were so big it was hard for bunch of 2nd graders to wrap our heads around. Of course we followed planes so we knew.
Awesome video . all hail the GE engineers I had a job delivering frozen chickens in Goodyear Arizona to their testing plant where they would fire them into the engines at full throttle it was amazing to watch
Did they thaw the chickens first? 😅
i remember as a kid reading about aircraft and noticing how often the J79 appear as the engine of a supersonic plane
The howl of the zipper, once heard one might not forget that sound. The marriage of that engine and airframe is amazing. Another great video. Excellent work as always.
Many thanks!
Great video and I will never forget the howl of the 104 on approach.
Same here!
Engines ! Excellent - Loud , smoky , cool ! Big power -

The photo of the 6 jets in the Valkie is amazing....would really be something to see that in person
Head over to Dayton, Ohio.
Ya been wanting to do that for a long time.....just dont go that way from Arizona@@zacklewis342

Never seen a Vigilante but will always remember those J79 smokey F4s. Wonderful.
Most Excellent Video. Love the boats and cars added at the end. Many super photos through out. THANK YOU!!!!
Love your work mate.😎😎😎❤️❤️❤️
This is the best thing I ever saw.
We have a vigilante in our little neighborhood of DeBary , Florida . She crashed after takeoff
From Sanford Naval Air Station when I was a kid in the’60 s Crew ejected - Now we are proud
To have a F-15 Eagle on a nice stick at our park . Great to visit , not fancy , just nice .
Thank you Mike, another great episode!

Next suggestion MiG-31M the king Kong interceptor
Good video, Mike. And lots of great info! I hope you will do videos on two more excellent jet engines - the J-57 and J-75. 😎👍
Already have one on the J57, and will post the great J75 early next year. Thanks for watching!

The GE photo shoot with the XB-70 was a disaster just for marketing!
Loved that painted picture of the vigilante at the start of the video! Where did you find that image? I’d like to use it as a wallpaper :)
Another good one.

What an interesting video. Great topic, Mike. It just seems like there’s no end to the different ways of looking at aviation. 👍
Well said!
Nouvelle Caravalle ❤ Oui.
Thanks for the video. Very informative. Quick pronunciation corrections on the Kfir… it’s pronounced K’fear (like beer, steer, or deer but with a very short Kh sound at the beginning, rather than Kh-fur). It literally means “lion cub” or “young lion”. The IAI subsidiary Bedek is pronounced BEH-deck (emphasis on the Beh).
Great video, I loved it, seeing all those great planes from my childhood. Just one little thing, Kfir mean lion cub, not lion. Thank you sir.
I’d love if you could cover the GE-4 more in-depth!
If memory serves correctly it’s the worlds most powerful after-burning turbojet!
I’ve only seen one or two videos that even mentioned the GE-4 in passing, and one single video of the engine actually running.

@@celebratingaviationwithmik9782 Sorry. l I mistook the B for a D.
Mike, a very enjoyable and informative watch. Got an idea; how about a vid on the history of Northrop University in Inglewood and other A&P schools.
Great video, Mike. I think the first GE jet was the 1-A rather than I-A, based on the Whittle/Powerjets W.1A.
Thanks for the comment. In an earlier video on the Bell XP-59, I said "GE One-A engine" and was corrected by a General Electric engineer who said it was the letters "I" and "A" on that sign. Thanks for watching!
@@celebratingaviationwithmik9782 Well, I guess that settles it :)
Should make a video on the TF39
The J79 also was in the F-4 Phantom. Great engines but unless you were flying in minimum burner, the Vietnamese could spot them since they were, unfortunately, very smokey.

but who doesn't love the J79 howling sounds?
Could we get the contributions by GE Space Division one day? They had huge role in manned and Unmanned flight & Exploring.
Prototype me262 had a propeller at front but it was no fake it had a piston engine and was to be used if jet engines failed in flight

*_I was going to guess: THE ENGINES_*
You nailed it! Thanks for watching.
How many J79's were produced total from all builders ?
4:15 is a sabre dog
At 10:00 you left out the Caravelle’s that United had. There were 20 of them. With the original engines they were UNDER powered
Yes, those were covered in detail in last week's video on Airbus. Thanks for watching!
GM = J33 engine - not the last or best GM Allison engines . Good times
U forgot to mention that the Super Tiger shot itself down!
Actually the standard F11F-1 Tiger did that, not the Super Tiger.
