I was in the 82nd Abn. from 1975 to 1978. A YC15 came in for a demo on Sicily drop zone in 1976 or 1977. It was an amazing looking aircraft. It looked like a baby C5. It was astonishing to see the flaps fully deployed. They came so close to the ground, it seemed you could climb up to the wing.
Did anyone jump it? I'm very familiar with Sicily DZ as I've jumped it for most of my jumps.
Jumped C-141Bs in Airborne School, and a bunch of C-130H and C-17A, some CH-47D and UH-60, with Twin Otter out at Camp MacKall.
Jumped into JRTC in Louisiana a bunch of times back-to-back in 2000.
In the end, the USAF realized they didn't need a C-130 replacement, but a C-141 replacement. That's why the USAF ended up with 222 C-17A's.
C-17A is awesome. Have jumped out of them many times.
Why was the C-141 retired so quickly?
@@3-DtimeCosmology The C-141's were just over-used from the time they entered service in the late 1960's. The planes started to develop wing cracking problems and they had to do a very expensive rebuild program for the entire fleet, and even that wasn't enough by the early 1990's.
@@3-DtimeCosmology It wasn't. C-141A was upgraded and extended with the C-141B mods. C-141 first flight was 1963. It was retired in 2006. It was first operational in 1965, so it had 41 years of operational service.
C-17A replaced and exceeded it capability-wise. My first jump was from a C-141B over Fryar DZ in Airborne School. C-141Bs were timed-out, many having exceeded their rated 30,000 flight hour lifespans.
In operational units, C-141Bs were always breaking down, spewing hydraulic fluid all over paratroopers, and it was an extremely uncomfortable ride with scores of dudes packed in there like sardines. C-17A was like riding in a Cadillac in comparison.
There is a C-17 at the Museum of The United States Air Force in Dayton that is off-gassing outside in the airpark now (or at least 11 mos ago). It is a Celebrity C-17 and has four or five Movie Camera icons painted on the side for Hollywood summer blockbuster type films it has been in. According to the docents it will eventually come inside. There is also a KC-135 parked across the way from the C-17, IIRC, that will be coming in. I forget where it is, but USAF also has a dedicated cargo/transportation aircraft museum with some good stuff.
It's also worth noting the C-17 is not a bad STOL aircraft in its own right. I'm sure the YC-14, YC-15, and C-130 all have the C-17 beat in that capacity, but for an aircraft as large as thd C-17 is, it can land on and take off from surprisingly short airstrips.
The engines used on the C-17 have a very unique thrust reverser. Most turbofans only use thrust reverser on the bypass air, which provides 80-90% the total thrust of the engine. The C-17 however also thrust reverses the core. The main reason for this is that it allows the aircraft to load cargo while the engines are running, as the thrust reverser prevents jet wash to the aft. But it also makes the thrust reverser slightly better since there is no longer reversed bypass thrust fighting core thrust.
... Also, I didnt know this until recently, but apparently the C-17 can deploy thrust reversers while flying. This is a bit unheard of, most aircraft use a weight on wheels switch to prevent midflight deployment of thrust reversers for safety reasons. In the C-17s case though, because they fit into a role that overlaps between the STOL use of C-130s, and the strategic use of C-5s, C-17s may need to make VERY rapid descents into contested airfields, in dangerous airspace, or may even need high descent rate to get into rough fields in mountainous valleys. So the engineers gave the pilots the ability to deploy reverse thrust in flight to achieve insane descent rates.
I was lucky enough to have seen this aircraft as well as the Boeing YC-14 at Davis-Monthan AFB before it was it was broken up. IIRC, the YC-15 was parked next to the YC-14. Great video!
Thanks, Ed. I knew very little about the YC-14 and even less about the YC-15. So, thanks to you, that is no longer the case. I know the Soviets took to the YC-14 design for the Antonov An 72/74 but as they have so many grass and dirty airstrips you can see why. Maybe take a look at their version at some point.
Ed Nash never disappoints.
thats what she said
Though I have found that most people disagree with anything...starting to bring everyone together with a small and underrated TH-cam channel that brings education and creativity to the front...we all agree. Cheers!
He alsi says "suffice it to say" rather than "needless to say." He talks the talk.
@@fakshen1973, Well, Ed is a guy who has also walked the walk...
Can you make a video about the recent developments in Myanmar? Especially the takeover of a border crossing to China by rebels in Shan state (something which absolutely could not have happened without at least tacit Chinese approval), and the moves against the so-called "scam centers" inside Myanmar. You have access to more and better information, and I am frankly confused - is China starting to support the rebels rather than the junta? That seems unlikely.
Very much on my imminent to do list, but like you trying to make sense of everything, especially all the territory that the army seem to have lost recently.
Wow glad i saw the camouflage YC-15 before they scraped it. Didn't know they did that. They should have loaned it to the Pima Air And Space Museum across the highway in Arizona and put it next to the YC-14. Great video footage.
The other YC-15 that they returned to flying status in 1996 was actually pulled out of the the Pima Air and Space Museum. I wonder if they made someone at MD mad :) My actual best guess is that there was some national security concern involved.
Always a renewed pleasure to watch your videos Mr Nash!👍
It shares the windows of the DC10.....like the C17....there are no little savings...
US Military doesn´t deserve a plane as cute as the YC-15 XD
Brings back memories of days of innovation and so many new aircraft coming to the field. I still love the looks of the Boeing, especially in the old TAC SEA camo scheme, but I have to agree that four engines are better than two in combat, especially for heavy-lift aircraft. Another excellent installment! Cheers!!
True about the days of innovation. But the C-130 is still out the and looks like it will be fore sometime to come.
This video hits home for me...Been working on C-17s sence 2004...
President Jimmy Carter was from Georgia and the Lockheed C-130 is built there.
No, that wasn't it. It was when the USAF realize they really needed a C-141 replacement, not a C-130 replacement, that the AMST program ended and we ended up with the C-17A Globemaster III.
5:10. The CFM-56 engine is the same one used on the KC-135R. It's a very powerful and relatively fuel efficient engine. It does, however, like to suck in any debris it can find, making it unsuitable for rough/dirt airstrips.
Thanks for including the stuff I commented on in the YC-14 video, though I suspect you already had this written. When the program that concluded with the C-17 was ongoing, there were LOTS of voices opposing the program because the range of the proposed aircraft was too short. In fact, it was WAY too short. The C-17's were designed for a "Red Storm Rising" style of theater war and we really needed a longer-range airlifter akin to the C-5. After 71 were built, the remainder were fitted with center-wing fuel tanks increasing range by about 15%. That's still not enough. Consider the C-5M and KC-10 have nearly twice the range with a similar cargo.
You are correct. One thing never discussed is that the C-17 did not meet its range specification. It was intended to meet the REFORGER mission profile, and fly a specified cargo load directly from the US to Germany without refueling. When the time came for proving runs to demonstrate this capability they knew the C-17 could not lift enough weight to meet this requirement. So they split the specified load across two aircraft and filled their fuel tanks to the brim. They then flew those two aircraft to Germany in formation and recorded it as a single mission. I don't know if Congress was fooled by that or not, but apparently it worked as a fig leaf and the airplane was produced. By that time we really needed the C-17 because the C-141 was structurally worn out and could not fly much longer.
Spending 4 tours overseas, I’ve had the pleasure to see almost every major Aircraft(A380 is my bucket list).

Had the YC-14 or YC-15 been built, then not only would they cut the sheer dominance of the C-130, the A400M may have been harder to justify.
I love how both designs look like cereal box toys 🤪
The '15 is damn sharp looking in that white and blue livery at the end!
C-123 please Ed? It's a sadly forgotten beauty that thing
Hey, it’s General Esperanza’s plane from Die Hard 2! 😂
Does anybody know why the second YC-15 was broken up? Would have been great to see it just down the street at the Pima Air and Space Museum where one of the YC-14s resides.
I've become a fan of both the YC-14 and the YC-15. At first glance, both aircraft have a slightly 'cute' appearance, but reading their history, and especially viewing the footage, one is immediately struck by how capable they come off. The YC-15 in particular gives the impression of great maneuverability. That tail-plane is almost a 2nd wing, and no doubt contributed to the aircraft's overall nimbleness.
The USA, by far, has the most advanced and robust supply-chain system in history. If a runway can be built there, the USAF can get it there and keep it supplied there.
Was waiting for this after the tease in the YC-14 vid 😊
Great content as always, Looks like an XC-142 video is in the works, or should be...
Thanks Ed .......this exemplifies how much money is poured into warfare . And the big guns in U.S aircraft development always seem to profit ....very well !!!
Its like an-72 only american
Vibey
There’s a long History of C-130 replacements following the mini C-17 Style and such Style creating the new Medium of Transport, the previously mentioned C-17
They are quite proven such as the Japanese completed C-1 and C-2
The C-130 is most certainly out of Date and needing a more forward thinking replacement soon
Though Wouldn’t say any of these Old drawn designs are Good enough, Their lessons Will prove Invaluable in It’s replacement though
I Hope It’s actually Innovative, not just a redundant dwarf C-17
It looks like a BAE-146
Should do a Caribou episode
The C-17 leveraged the YC15 and the DC10 programs. The DC10 contributed a lot to the power/Avionics/and maintainability.
0:47 no problem everthing comes from BREGUET 🇫🇷 ( not brejett) looks like 200 meters to take of was too weird and super flaps also.. we buid FOUR 😂and is also known as macdonel douglas 188.
Thx for very good video my englis is bad finally C17 has french bood ? 😂 We might ALL have rushed at ANTONOV ... poor incredible peacefull company... destroyed..😢. Biggest carrier is... dead 😢
YC-15 is remarkably similar to the Armstrong Whitworth AW681 STOL project from 10 years earlier, sadly cancelled before the prototype was built in 1965. This marked the end of Armstrong Whitworth as an aircraft manufacturer within Hawker Siddeley Group and the loss of 5000 jobs.
A YC-15 sized aircraft with STOL capabilities would be perfect for near frontline resupply: small arms, ammo, food, water, medical supplies, personnel gear, electronic equipment, drones, anti-tank weapons, anti- insurgence troops, special ops forces, utilizing scarce technical personnel like medics, dappers, engineers, electronic weapons techs, ...,
A decent strategic tactician would have a massive increase in options for offensive, defense, covert, special, and other operations. Such a plane would also be valuable in supplying resistance groups behind the front lines.
How different would the Crimea battlefield be if multiple loads of fully supplied special ops teams backed with anti-whatever missiles, drone fleets, and light artillery could be dropped near any objective, like the Kirsch Bridge, major transport hubs, Sevastopol Harbor?
But wait. My bad. That would make it useful, expense conscious, flexible, and ideal.
Can't have that in a military budget.
Thanks for the update I was wondering what happened to these aircraft. I was just getting out of high school and going to college so I lost track of what happened to them.
Nice C-141 Landing Shot - I worked Dover AFB Transit Maint. almost 3 years .
Good stuff. But, use Babble. English is but one of 7000 languages in the world. France is just on the other side of that puddle you call the channel. Bresheii (Breguet), please.
Looks similar to a BAE-146. Similar engine tail configuration, although tail is much higher on this one probably for the tail ramp loading.
I'm wondering how the the new Embraer military cargo plane (dyslexia is on) is related, since it also plans to replace the C130.
Unbeatable Embraer Millennium C-390 best value for money 💸💰💵💷
Best seller
I wonder if you should do a video on the YA-7F. I don't see it in your list. Would be awesome.
You do great work. Love the coverage of modern "also rans." Thanks!
Hey Ed, can you cover the ongoing fighting in Myanmar? Thanks.
Yeah a turbo prop cannot be replaced by a turbo fan jet and vice versa that is why two aircraft where the right way to go funny no matter what kind of engineer you hire they cannot over come physics
I cannot believe they broke up the YC-15. Why😢
Hey Nash wake up operation 1027 just drop
YC-15 it what was needed for Operation Eagle Claw
Some say that if you put one of these in water, you'll get a C-17
I love the proportions of this plane!
The cockpit…DC-10 both YC-15 & C-17 (great vid too Ed👍🏻)new subscriber!)
Welcome aboard 😉
Yc15 kind of looks like a shrunk down C17.
HS Avro regional jet on steroids, surely?
Esthetically the YC-15 looks better.
At 08:54 in this video:
Ed, I think you showed a brief glimpse of this aircraft in your YC-14 video. {Or it appeared briefly in SOMEBODY'S video.}
Now I know what it is...👍
So in short: it was a good plane, but the plan changed.
Several years ago I was at Daugherty Field ( LB Airport) making a delivery, and this white YC15 craft was taxing by the main terminal, much smaller than the C17, and realized it was one of the prototypes I had heard about in Jr high from a Douglass exec whose daughter was my 7th grade teacher. Got to see one of the last export C17 production models test flying before the end of production. Thnx for the informative video.
amazing
Can you do a video on the Transall C-160?
I really wonder how much Jimmy Carter's ax wielding had to do with the cancelation?
a ton....Jimmy Carter was totally 100% incompetent.....
Last I looked the YC-15 is sitting just outside the main gate, so anybody can take the side trip down Rosamond Blvd. and see it, along with an assortment of century fighters. A fun sidebar.
Boeing channeling the Antonov AN-72.
Looks just like an AN 72/74
I wonder how much air america had to do with all this
only thing missing is a gunship varrient!
Does this mean we are getting an An-72 Coaler/Cheburashka video next?
It’s a shame these aircraft didn’t get built they did what was asked but changing requirements put an end to it. I wonder what the civil market would have thought.
and now embraer has the c390
So the soviets bought the yc-14
Nice one, Ed -- thanks!
Mr. Nash, how about a video of a plane with no name? The O-47.
Thanks Mr Ed Nash.....
Old Shoe🇺🇸
The incessant vacillation of the military requisition process!
Awwww its a big boy Bae 146
*Great video, Ed...👍*
Wow great job 👍👍👏👏🙌🙌
Looks like a mini C-17
Very sad we didn't get that beautiful Boeing tri-jet
Yeet cannon 15….
This is like the older brother to the baby C-5 or AC-130
PG!
Concise video. Thanks
Excellent.
Pretty neat.
( propaganda)
Isn't this the plane in Con Air?
No. That was a Fairchild C-123 Provider.
Its sad that the YC-15 and its fellow types never saw production, but to think it gave us the glory that is the C17.
