Tour around the Northrop YF-23 - the best fighter jet never built?

[@PaulStewartAviation]

Thanks for watching everyone. Several people have commented on the name of PAV-2. Inside the nose landing wheel well, you'll see the name 'SPIDER' printed and this can be seen in numerous photos and videos.

Sad to see the poor girl sitting out in the sun, while the other ship sits in glorious company in Dayton. Has anyone described how the Black Widow name came about? That there are two orange/red danger signs painted on the belly that turned out to look like an hourglass

[@colin5577]

The F22 is an incredible bit of kit and it still looks like something 20 years ahead of its time. But the YF23 looks like something aliens left behind. It’s jaw dropping.

[@thomasbarrack1384]

The YF-23 actually outperformed the F-22 on various metrics, which many people are unaware of. It was actually faster than the F-22 in supercruise and with afterburners. It had a smaller radar cross-section from all but one direction. The military chose the F-22 because of Lockheed consistency, previous experience with stealth, and because the design was more conservative and traditional. With Northrop's successful but massively over budget B-2 program that experienced cost overruns and time delays, the military opted for the lockheed model.

[@Mecha_for_nothing]

@@thomasbarrack1384 does yf 23 really had longer range than f22

[@nateh4467]

@@thomasbarrack1384 In addition northrop was going thru some issues in the 80s and any government project is all about how well you pay the politicians. The f22 barely got off the ground the day of testing.

[@CONSOLETRUTH2]

@@thomasbarrack1384 not to me tonight that the USAF had a grudge going way back against Jack Northop, the company founder, due to his original flying wing bomber concept that started back after WWII and the many issues (budget, delays, etc.) so that did not help either. Add in the fact that the F-23 didn't have thrust vectoring engines and that it fell behind in demonstrations (such as the F-22 early on demonstrating its weapon firing ability from the internal bays whi h the F-23 never actually demonstrated whereas the F-22 did this VERY early on in testing) and with everything combined hurt and eventually ended the chances of Northrop winning the USAF contract. Personally, while I understand why, at the end. the F-22 was chosen, I personally wish the F-23 would have been chosen as it is still an amazing aircraft and is just BEYOND a beautiful design. I won't take anything away from the F-22 as it too is an AMAZING aircraft and is king of the skies and most likely will be for sometime. At the very least, China has a cheap dollar store knock off that may soon be flying the skies AND Japan has seemingly taken an interest in the design so much that a future Japaneae craft will most likely resemble one as well.

[@thomasbarrack1384]

@@CONSOLETRUTH2 too much to respond to. The delays and cost overruns actually make sense as to why they happened. They build a giant bomber that is more stealthy than even the F-22 raptor, and started designing it earlier. Computing power wasn't enough back in those days to use for figuring out how to manufacture and produce all the parts and equipment. The B-2 was the most advanced, stealthiest, and capable bomber, and possible aircraft the world had ever seen. And they had no one else's work to draw off of. Innovating isn't always timely. Regarding the f-23, its own designers stated that they went without thrust vectoring because it wasn't needed to achieve desired maneuvering capabilities, the futuristic design of the aircraft in tandem with it's superior thrust to the F-22 made it just as capable if not more. The military has a pattern of favoring Lockheed, some of which is due to the deep state and politicians trying to keep jobs in their states for constituants, and the other was that the F-22 was viewed as a natural progression of the f-15 where the f-23 was futuristic and would be harder to sell to the public. At bottom the f-22 won becsuse of politics and bureaucracy, not solely on it's merit as an ATF

[@mabbook]

People forget that the competition was for an air superiority fighter and the f-22 with its thrust vectoring was better for that role. In hindsight the YF-23 might have been the better choice for the fighters needed today. But the truth is if it had been an F-23 today there would been videos and people talking about the YF-22 and how it was better and should have been selected. Both these planes are amazing with different strengths and weaknesses and probably both should have been made.

[@archangel9303]

Exactly!

[@Brandonthesnifferofall]

Agreed.. we should add 360 trust vectoring to the YF-23 and build them 😂🇺🇸🦅

[@ltcuddles685]

Literally the only thing the F-22 had over the yf-23 was politics. The YF-23 was faster, stealthier, and had greater weapons options. In an air superiority role in this modern day thrust vectoring means nothing on a stealth jet, if a stealth fighter is in dogfight distance it's made many mistakes to find itself there.

[@vevenaneathna]

feel like the yf23's higher preference given to stealth would have aged better with what missiles are able to do and the fact that su57 is basically maxxed out on anti stealth tech and j20 is no where near stealthy. im bothered that china realizes stuff could pop off soon and started production on their j35 competitor model even though it lost to j20. kinda feel like were putting all our eggs in 1 basket with f35 but atleast were making them way faster than china can for way cheaper. especially f16 legacy models that theyre starting to mass produce in india. with a potential fly away cost of 10-15m per f16, it might cost russia more in s400 missiles to shoot one down that it will for the US to make lol

[@rickhunter6513]

Me too. I was so disappointed when they selected the “safe” pick. The F22 is pretty awesome but the F23 was something special

[@MaestroAbar]

YF23's diverterless supersonic inlet was truly ahead of its time. It had many engineering characteristics that were superior to a more "conservative" YF22's design.

[@5ch4cht3l7]

Agreed. The choice between the YF22 and the Y23 was probably also about conservative vs. innovative, and they probably wanted to avoid the risk of the more innovative stuff having problems and increasing the cost. The F22 already turned out to be pretty expensive, now imagine the F23 having problems with any of the unconventional stuff. Not saying that it would, just that there is always the risk

[@bazejs8084]

Yes but just before they selected the winner USSR collapsed, with that USAF lost the only near-pear adversry capable to present any challenge and financing of the program collapsed as well. The best performance options was considered YF-23 with GE engines and the cheapest combination was YF-22 with PW engines. They practically had to select the cheapest YF-22/PW combination still barely saving the program at all. Additionally USAF was forced to reduce the program from initial 700 airframes to 190.

[@VistokDB]

thats just says that both aircraft were truly ahead of its time.

[@joeclaridy]

It's a sham, the Air Force knew the YF-23 was the better option but because of politics the F-22 got the nod. Northrop shot themselves in the foot due to controversies involving previous programs like the B-2 that went way over budget. The Pentagon possibly believed this was going to be another fiasco were they over pay for a new fighter.

[@MaestroAbar]

@@joeclaridy The biggest issue was the YF23 was just a mockup with placeholder electronics/software, while the YF22, although early stage, had a working proof of concept. Military tend to be conservative with their projects, and understandably, they went with a more certain option.

How great would it have been to see a fleet of F-23s flying off of carriers.

But it was a usaf concept so it would never have flown off of carriers plus the navy already has the f35

[@thelandofnod123]

@@Ian4bis Sure, this was also well before the F-35s time, even before the Super Hornet. As was the case of the Classic Hornet being developed out of a competition for a USAF aircraft, the production F-23 (or what ever it would have become had it been developed further) could have been a replacement for the Classic Hornets and the Tomcats. But as we know from the F-22, there was just no where near enough money for that to happen with the cost of either of these machines, hence the Super Hornet and now the F-35.

[@thelandofnod123]

@@omarhossam789 The chief reason for selecting the LM project was that the government was more assured that LM could manage the program. Their faith in NG at the time was quite shakey. The LM project at the time of testing was quite a bit more mature than the NG project. While I’m not sold on the USAF wanting an aircraft because it would have been an easier conversion for the Navy, the US did look briefly at a version of the Raptor to replace the F-14. The idea was that the Navy could leverage the F-22 program and the USAF could leverage the A-12 program to create a replacement for the F-111. However with the cancellation of the A-12 this never happened. The F-22 proposed for carrier ops was swing wing (obviously with a bunch of other major changes to the platform to make it suitable) and was finally judged to be too difficult and expensive to complete or justify generally due to the projections that this would not provide any advantage over the current fleet that the Navy operated nor lessen the cost burden on the F-22 program (at the time a production Raptor had not even flown and already cost estimates were blown out and procurement numbers were coming down). Anyway, we know the Navy got Super Hornets and the USAF got naff all Raptors. The Raptors may get upgrades to prolong their service into the future out of the NGAD program however that program looks likely to go in a different direction to current platforms.

The chines also avoid creeping waves. This is where radar waves coming in from abeam "stick" to the circular cross section of the fuselage, wrap around it and are then sent back in the direction of the receiver - like doing a 180 on a roundabout. Instead they spill off the fuselage at the chines and away from the radar.

Paul great vlog as always

[@vmpgsc]

Details in your narration are spot on - thank you for doing the research. Northrop/MD already had a developed configuration for the production F-23A which would have split the weapons bay into two bays, reprofiled the "bread loaves" over the engines to be smaller to reflect the deletion of a thrust reverser requirement, and replaced the boundary-layer plates in the intake with diverterless supersonic inlet (DSI) design.

[@PaulStewartAviation]

Glad you enjoyed it. I'm off to Dayton later this month for more filming

[@rbrtck]

Yeah, the bay was split into a forward bay for the 2 Sidewinders and an aft main bay carrying 4 AMRAAMs stacked in a 2x2 configuration. I've always wondered about the change in the type of intake, and have to think that this represented quite a bit of risk that could have been reduced by the demonstration but obviously was not. The F-23 ended up being more different from the YF-23 than the F-22 was different from the YF-22.

That is false. After award, the Air Force and Lockheed conducted further testing with the YF-22 and that is the aircraft that suffered the belly landing. The software hiccup with the YF-23 was during taxi. If you watch early taxi tests, the flight control surfaces are moving as the flight control system reacts to bumps on the runway.

The F-4 and a few other aircraft had what is called "BLC" or "boundary layer control" systems which helped control the boundary layer by taking bleed air from the engines and blowing it across the leading edge of the wings to provide lift and prevent boundary layer separation and other issues. If the BLC warning light went on and stayed on after the bold-face procedure was performed and you were below 10,000 feet, that was an ejection event... That's because of the higher wing loading, combined with low speeds can lead to boundary layer separation, which will immediately cause depression to set in.....

Imagine having those large tail fins and thrust vectoring

i allways wanted the YF23 to win the contract , it looks amazing , and those 50 degee tailplanes look massive , and how deep is that engine from the back , and mixing cold air into the jet blast !! once again paul thanks !

9:00 yeah but I’ve seen it has its Own Unique Cockpit interior as well from Video games and I want to know Why !? Can’t find it Anywhere on Internet though I guess it was the prototype Cockpit !?

[@yeetboiaug9615]

F22 is one one my favourites but the yf23 is just a beautiful aircraft

[@gregperia3820]

Great video with lots of info. Just one bit of clarification. I believe the displayed engine is actually the non-selected General Electric YF-120. I don't know a great deal about aircraft but engines are all I have done for 40 years and I have seen early YF119 engines. That is a YF-120. Again great video just an attempt to correct one small point.

Cheers, thanks!

Best looking airplane I’ve ever seen, every line, every angle is so sexy, the tail is gorgeous and it cuts a silhouette like a high end Lamborghini, 20 years before they started looking the way they do.

This is just totally awesome

[@herosjourney8725]

this plane has always been awesome!!!!!

[@Robert-ff9wf]

Honestly from what I know, this should have won and should be our front line fighter!

[@jeanmichelorzechowski6307]

Really, it's a very beautiful plane. I would have liked to see it up close. What about the cockpit. Thanks again for your video. I was a mechanic engineer on Mirage F1 and Mirage 2000 in the French Air Force.

I remember I used to see this plane outside of the air museum by the Northrop plant in Hawthorne CA, and always wondered “why are they letting it rot?” It’s an awesome looking plane. Thanks for this video because I know now it’s in good hands.
