1
This is the F-15EX, the US Air Force's newest fighter jet.
2
But for the last 20 years, we've been told that the future of aerial combat is stealth and unmanned aircraft.
3
So why does the future look like this?
4
To answer that question, we're diving into this jet's history, getting rare access with an F-15 test pilot, and ending it all with one of the craziest flights of my life.
5
All right, Sam, you want to go ahead and fly?
6
Let's do it.
7
All right, go.
8
Absolutely incredible.
9
So we're about to walk into building 75, which is Boeing's final assembly, where they finished manufacturing all of their latest aircraft to be delivered to the U.S military
10
and allied countries all over the world.
11
Now, it's one of the coolest hangars I've ever seen, and I want to show you why.
12
All right, here we go.
13
Safety glasses on.
14
Now back behind me is the F-18 Super Hornet, and in front of me is an aircraft I'm seeing for the very first time, the T-7 Red Hawk, which is gonna be used to train fighter pilots for years to come.
15
But over this way is the aircraft I'm really excited to introduce you to.
16
It's what the subject of this video is all about, the F-15EX.
17
It was built off the design of the F-15E Strike Eagle that first flew back in 1986, and if you put up a photo of the two aircraft side by side,
18
through the untrained eye, it looked pretty similar.
19
But that's about where the similarities end, because this EX is by far the most advanced and tricked out version of the Eagle ever built.
20
To help us learn more about this platform, there's someone I want to introduce you to.
21
His name is Lieutenant Colonel Matthew Oldey, callsign Kane, and he knows more about this aircraft and what it's like to fly it than just about anyone else.
22
Lieutenant Colonel Oldey, great to meet you.
23
Good to meet you.
24
Now, I want to make sure the viewers understand your job because it's fascinating, right?
25
So whenever Boeing rolls one of these new EXs off the production line, it first comes to you.
26
You're an active duty Air Force pilot and you get to test this jet, right?
27
Put it through the ringer to make sure it's ready to be handed off to the active duty Air Force, right?
28
Do I have that correct?
29
Effectively, yeah.
30
After it comes off the assembly line, the Boeing test pilots fly it and then they hand it to me as the Air Force representative here with my backseater.
31
And then we flip every switch, we take it to the edge of the envelope, restart motors at the edge of the envelope to make sure that it's ready to go to the United States Air Force.
32
So a little bit later on, That is actually the flight.
33
I'm gonna be in the back seat with Cain to see what that is like.
34
But before we do that, I'd love for you to take us on a little bit
35
of a walk around to learn what makes the EX so unique.
36
Absolutely, let's go.
37
The F-15 EX is the latest F-15 to be produced here at Boeing St. Louis for the United States Air Force.
38
Previous versions of the F-15 were mechanical flight controls.
39
So the pilot would actuate an input, the flight controls would be actuated in the direction that the pilot wanted.
40
With fly-by-wire, the pilot has a vote.
41
The computer takes that information and goes, I think that the pilot wants to move the jet in this way.
42
And what that allows for is an incredibly maneuverable F-15, and you'll see that on our flight.
43
So let's talk about this radar, because I know it's one of the most powerful radars to ever be in an F-15.
44
What does that allow you guys to do?
45
Yeah, ASA radar, it's an electronic beam that is manipulated and moved by the computer.
46
And so you effectively turn the corner and you see the entire airspace, all the contacts.
47
When we take off out of St. Louis, we're gonna level off and we're gonna see every airliner that's out there almost instantly.
48
Moving on to the weapons on this aircraft, the M61A1 gun, 20 millimeter round that it shoots, multiple different kinds of rounds.
49
It can also carry those 12 advanced missiles plus bombs.
50
So I'm trying to do the math here.
51
So for 12, what does that look like?
52
How many on the wings?
53
How many actually are underneath?
54
So you're gonna have two on the outboard station, two on the inboard station there, that's eight total.
55
And then you're gonna have two down here on the shoulder stations, and then two on the other side on the shoulder stations.
56
So that's 12 total AMRAPs.
57
The reason you can carry so many missiles is because you guys aren't trying to be stealthy.
58
Absolutely, nothing carries more than the F-15EX.
59
So we're now gonna take you for a look inside the cockpit, and this is where you can really see the advancements of decades of newer technology over the legacy F-15 Eagle.
60
But I had to stop right here because look at that.
61
That's what the Boeing team here surprised me with.
62
We've done a lot of flights.
63
I've never had my name actually on the side of the aircraft, which is pretty sweet.
64
And I realized after we take a look inside, the next time I'll be on this ladder, the stairs walking up will be for my actual flight.
65
So better get myself a little bit familiarized.
66
All right, welcome to the front cockpit of the F-15 EX.
67
It does not look like a legacy F-15 cockpit in any way.
68
This 19 inch wide, large area display, 1080, all touchscreen.
69
One of the checks we do is a roll emitter check
70
and you slam the stick as hard as you can at Mach 0.95 at low altitude, so 10,000 feet.
71
You're going to get, you know, 8.8, 8.9, 9.0 Gs.
72
You're looking for the jet to protect itself.
73
Never rip the wings off yet.
74
Nice.
75
It's probably a good time to ask about the backseat.
76
What's the role of the backseater?
77
Can it do everything you can do here in the front?
78
So the backseat has full flight controls.
79
The stick and the throttle in the backseat.
80
The Wizzo in the back seat's gonna manage all the sensors, all the weapons with those two hand controllers.
81
It's probably as comfy as a ride as you can get in a fighter jet these days, I feel like.
82
I agree with you.
83
You got space for some bags if you go cross country.
84
I'm very blessed to be able to do this for as many years as I have, and I wouldn't change anything.
85
Well, Cain, thank you so much for the tour of this aircraft, and I hope everyone can see just how impressive it is.
86
But when talking about the EX, you have to go back and talk about the history of the legendary F-15 platform.
87
And there's one record that's so insane, it will absolutely blow your mind.
88
The F-15 has an air-to-air kill ratio of 106 to zero.
89
That means the Eagle has shot down 106 enemy aircraft without
90
being shot down itself over the last five decades since this plane first flew.
91
That number is almost hard to comprehend today
92
and is a stat that's made the F-15 known as one of the most successful fighter jets in history.
93
But to understand why the newest version, the EX, even exists, you have to understand how a jet designed in the late 1960s became
94
so dominant that over 50 years later, Boeing is still building the next evolution of it.
95
The airplane we're unveiling today represents a major addition to our foundation of strength.
96
The F-15A was the original single-seat version of the Eagle that was first introduced to the world back in 1972.
97
I christen the Eagle and may you reign in your domain.
98
This was just five years after the Soviet Union revealed its MiG-25 Foxbat,
99
a high-speed, high-altitude interceptor aircraft that made the United States realize they needed an answer.
100
And did they ever get one?
101
For the first time, a fighter jet could spot enemy aircraft from far away, could shoot at them before they knew what was coming,
102
could outrun almost anything that tried to escape and could outmaneuver opponents that tried to fight back.
103
The F-15A was better at basically everything that mattered.
104
Now in 1979, the single-seat F-15C variant entered production.
105
It featured a more advanced radar, heavier payloads, and a game-changing piece of technology known as conformal fuel tanks
106
that shaped the aircraft's body to add additional range without sacrificing maneuverability.
107
In 1986, a new version of the F-15 entered the scene, the F-15E Strike Eagle.
108
With massive conformal fuel tanks for huge range, a backseat weapons systems officer to manage sensors and targeting,
109
and the ability to carry a huge bomb load while still defending itself in combat, the Strike Eagle turned the original F-15 into a true dual-role fighter.
110
Which is when something interesting happened.
111
Other countries who had been flying variants of the F-15 for decades expressed interest in a newer, more modern version of this aircraft with some major upgrades.
112
We're talking about AESA radars, digital glass cockpits, fly-by-wire controls, and much more.
113
These jets became known as the Advanced Eagle Variants.
114
At the same time, back here in the United States, the US Air Force had a problem.
115
Their fleet of F-15Cs were getting old.
116
So instead of starting from scratch, they made a calculated decision.
117
Take everything learned from the Strike Eagle, take everything learned from the Advanced Eagle Program, and put it into one jet.
118
And that's how we arrive here with the F-15EX.
119
Now if you were paying attention earlier during the walk around you may have noticed
120
that there was one very important thing we left out.
121
The engines.
122
And I promise you that was intentional.
123
You're about to see why.
124
These are two General Electric F110-129 turbofan after burning engines which produce nearly 29,000 pounds of thrust apiece piece.
125
So when combined, that's about 60,000 pounds of thrust, which is what allows the F-15 to accelerate to two
126
and a half times the speed of sound and carry roughly 15 tons of weapons.
127
Now to really feel that thrust, Boeing is going to show us something that I've never seen before.
128
A full-up engine run with this aircraft strapped down right here in this hangar.
129
Now they call this area the hush house
130
because this is about 80 feet of hollowed out tunnel and right now we're directly behind the engines of the F-15.
131
Now from what I've been told is that when they do the burner run, the plume of the engine of the afterburner actually extends about 20 feet, which is about right here.
132
So I can't imagine how loud this is going to be, but we're going to find out.
133
The anticipation, I'm nervous.
134
I didn't even think you could stand this close to a fighter jet at full burner, but here we go.
135
Oh, bleep.
136
That was insane.
137
Oh, bleep.
138
Well, that was crazy.
139
And from what I've been told, the only thing crazier than seeing an F15 engine run from up close is feeling it from even closer.
140
So it's about that time.
141
I'm ready to get briefed up, geared up, and strapped in for a backseat ride in the F-15EX.
142
All right, air check.
143
Hack, 1030.
144
Welcome to Mack Flight.
145
The weather's beautiful here.
146
We've got a tap that shows a little bit low cloud.
147
Today we're going to do what's called an acceptance check flight.
148
We are going to run the aircraft through its paces, push it to the edge of the envelope, flip every switch, basically flush the aircraft out.
149
Initially, you and I, we're gonna climb high.
150
We're gonna do the Mach run.
151
We're gonna spiral descent down into the Mach North.
152
And then we're gonna go pull some Gs.
153
We're gonna fly high AOA.
154
We're gonna see more than 40 degrees AOA.
155
By the end of the runway, we're gonna be fast.
156
So it's gonna happen really quick.
157
45,000 feet, we'll just point straight at the ground.
158
And then we'll just spiral descent.
159
We'll just kind of fall like a leaf.
160
We're gonna be screaming.
161
And then keep your legs out of the way because I'm gonna jam the stick over to the left.
162
If you did that in a Legacy Eagle, it would bend the wings.
163
It will knock you out.
164
It will put you to sleep if you're not careful.
165
What I think Sam can expect on this flight, I've watched his other videos, the Test Pilot School video, I watched the Viper demo video, and those are two extremes.
166
But today, I think he's gonna experience like just pure joy of flying.
167
We're gonna go out, it's gonna be a beautiful day in a clean eagle, and we're gonna go Mach 2, we're gonna go high OA, we're gonna do brake turns, we're gonna get some gas, and we're gonna do it all over again.
168
So it's gonna be pretty cool.
169
Viking north with an unrestricted climb up to 25 block 30 on request.
170
Way to your fans.
171
Let's roll!
172
I planted a few fighters who are never on a commercial runway here.
173
I know, you see the windows and I just hope that there's little kids in the windows looking and dreaming.
174
With the Viking departure out of here, every single time we fly, we do an unrestricted climb.
175
It's a rocket ship and the engines are operating at max thrust on
176
that departure and so it's like nothing he's ever experienced before.
177
EGT zero stabilizing.
178
You ready to rock?
179
I'm ready to rock.
180
All right.
181
Point three zero right.
182
Clear forward takeoff.
183
Three seven four.
184
Clear forward takeoff.
185
Three zero right.
186
Remember heading.
187
Welcome.
188
It's 50.
189
Woo!
190
60. 100.
191
Oh my god.
192
Oh my god. And open out.
193
Absolutely incredible.
194
I flew 74, we're going to change the proofs to it.
195
Wow.
196
Look at the...
197
And it's 277, we're at 2,000 feet.
198
Wow.
199
So just like that, we're at 41,000.
200
I'll see center-lock with some boards in the under-shift climb.
201
Pretty cool, huh?
202
That was incredible.
203
It feels like a Viking.
204
It is nasty.
205
I've always heard the F-15 is like a hard jet to fly.
206
Is the EX easy or still pretty difficult?
207
The F-15 takes a lot of finesse and technique.
208
Certainly this one does too, but it is more forgiving, which is good because it allows you to focus on employing it as a weapon.
209
First up on the checklist is a test of raw speed.
210
We have to prove this new airframe can handle the intense stress,
211
so Kane is about to push the F-15EX beyond Mach 2 to make sure it handles supersonic speeds without tearing itself apart.
212
1.0, Hack.
213
Alright, we're officially supersonic.
214
Are you ready to get Mach 2?
215
Let's do it.
216
Alright, max AB.
217
Coming up on 2, Hack.
218
Alright, so I will bring the power back to min AB.
219
Go on, decel.
220
It's crazy, huh?
221
With the speedrun checked off, Kane is taking us into the most unpredictable phase of the A deliberate spiraling freefall.
222
We're dropping 20,000 feet straight out of the sky to prove
223
that the jet's flight computers and engines can survive the absolute worst aerodynamic conditions.
224
Pull up.
225
Pull up.
226
Pull up.
227
Pull up.
228
Pull up.
229
Pull up.
230
Pretty cool, huh?
231
Yeah, it's not often you're pointed straight at the ground.
232
Yeah, from 45,000 feet exactly.
233
Remember I told you how this thing doesn't like to slow down?
234
Alright man, the first one's gonna be the nose high low speed recovery, like we briefed.
235
Okay.
236
The nose high low speed recovery.
237
Essentially, we're flying this 100 million dollar fighter jet into a dead stall.
238
At this extreme pitch in low speed, the wings lose all lift, leaving our survival in the hands of the flight computers.
239
Alright, you ready?
240
Let's do it.
241
Max.
242
Ready.
243
Ready.
244
Now. With the jet recovering
245
in what felt like the blink of an eye, it was then on to the next item on our checklist.
246
Basic fighter maneuvers, also known as dogfighting.
247
We'd be simulating flying slow, low to the ground, with an enemy right on our tail.
248
To survive, Kane is going to intentionally upset the aerodynamics of the EX, snapping the tail to make the aircraft violently jerk and break the enemy's weapon tracking.
249
Wow.
250
Bingo, fuel.
251
Bingo, fuel.
252
Alright.
253
Tally the tankers?
254
Yeah man, just in time, we need some gas.
255
Aerial refueling, one of the most critical capabilities in modern air power, and a vital system to test before signing off a new aircraft.
256
It allows the F-15EX to stay airborne longer, fly farther, and reach the fight without stopping to refuel on the ground.
257
So as we linked up with a nearby KC-135 strato tanker, it was time for Kane to show me exactly how it's done.
258
Jake, get heavier if you take on a lot.
259
Yeah, absolutely.
260
Yeah, that's a thousand.
261
Work, thank you, just turn. Have a flying, boys.
262
Appreciate that.
263
We're gonna shut down a motor.
264
You ready to shut down a motor?
265
Alright, let's shut down an engine.
266
Normally you don't want to hear that, but uh, that's what you guys gotta check for, huh?
267
That's correct.
268
All these are just crazy.
269
It sounds like an insane idea, but as an acceptance test pilot, Kane has to prove that if an engine ever fails in combat, it can safely be restarted in midair.
270
All right, go to the right side, left side's coming off.
271
Fuel flow going down to zero.
272
Caution.
273
Caution. And 50%.
274
Easy peasy, pretty benign.
275
Step's coming up, fuel flows up, power cams up.
276
Feel that motor kind of kick in.
277
Yeah.
278
All right, motor left side is now matched to the right.
279
Alright, Sam, you wanna go ahead and fly?
280
Let's do it!
281
Alright, Sam.
282
And red from blue, backseat's gonna fly for 15 minutes.
283
You guys ready?
284
Cuff that and back off.
285
14,000 feet, about 320 knots.
286
Urgent.
287
Alright, I have the aircraft.
288
Alright, roll left, man.
289
Make sure we go left.
290
Here we go.
291
3, 2, 1.
292
Harder, harder.
293
There you go.
294
Thanks.
295
Last time I did that the thought was somebody to go slow.
296
You were like, go harder, harder.
297
Oh no, watch, watch.
298
My jet.
299
Your jet, your jet.
300
Watch this.
301
Watch this.
302
Whoa!
303
Okay, alright.
304
Alright, show off.
305
That's what you gotta do.
306
A little harder.
307
Alright, your jet.
308
Alright, I have the aircraft.
309
You have the aircraft.
310
You want to try a brake turn?
311
Yeah, walk me through it.
312
Alright, about 400 knots, you're gonna roll about a 90 to 110 degrees of bank, and then you are going to pull as hard as you can straight back.
313
Kane is telling me to pull back on the stick as hard as I can.
314
In older jets, doing that could literally rip the wings off the aircraft.
315
We're testing the Over G protection software, proving that no matter how hard or violently I wrench this stick, the flight computer will step in,
316
cap the g-forces, and protect both the airframe in my life.
317
At least that's what's supposed to happen.
318
If there's a flaw, Kane and I are about to find it, the hard way.
319
That was 8 Gs, not bad.
320
Only about 8.3.
321
That was a little bit fast.
322
Wow. That was insane.
323
I was like graying out.
324
The onset's crazy.
325
It's just like...
326
It's almost instantaneous.
327
I do it in the sim once.
328
You don't feel the Gs.
329
It's completely different.
330
Yeah, exactly.
331
Good job, though.
332
Thanks.
333
That was awesome.
334
You could not have done that in an active eagle because you might have over-Ged.
335
Yeah, I was going to say, normally it's not pulling as hard as you can.
336
I was like, all right.
337
So what role do you see the F-15EX playing in this era where we hear a fifth generation stealth fighter jets?
338
This isn't that, but it's still pretty damn impressive.
339
It's got wall-to-wall missiles plus air-to-surface bombs, gas for days, and with an incredible radar,
340
all those things combined, it's going to be a formidable addition to the overall CAF fleet.
341
DCMA is responsible for every step along the assembly line.
342
I represent the 10,000 folks across the agency.
343
Right.
344
This is just one piece of that overall process of delivering the combat capability to the D.O.W.
345
This jet's gonna go to my brothers and sisters in the fight, and we wanna make sure it is the right piece of equipment at the right time.
346
I think that sums it up perfectly.
347
I mean, it's a fun job, but it's a job with a ton of responsibility.
348
So do you ever get tempted to fly through the arch?
349
All the time.
350
It was time to head back to base and call it a day, but before we touch down, Kane had one last surprise in store.
351
Wow.
352
Pretty fun, huh?
353
Yeah.
354
I bet that was loud on the ground.
355
That's the point.
356
So at the very beginning of this video, I said it was our goal to answer the question about why the future looks like this.
357
It's true, this jet doesn't win by being stealthy or being invisible, but it wins by carrying more, flying faster, and outlasting pretty much everything else in the sky.
358
Cain, that was incredible, man.
359
So what do you say?
360
Did this jet pass the test?
361
Is the Air Force ready for it?
362
We will buy it.
363
Passed.
364
Heck yeah, man.
365
Well, I got one more thing for you.
366
Figured I'd just do a little swap here, pull that off, put the Axis Granite patch on.
367
Nice.
368
We did it, man.
369
Thanks so much for having me.
370
Thank you.
371
Hope you guys enjoyed.
372
We'll catch you next time.

Phát âm cần chú ý
Người nói dùng 115 dạng rút gọn, ví dụ gonna, we're, I'm. Hãy nói theo dạng ngắn đúng như bạn nghe.
- Âm “th”: thrust /θɹʌst/, stealthy /ˈstɛlθi/, stealth /stɛlθ/, underneath /ˌʌndɚˈniθ/, mathematics /mæθ(.ə)ˈmæt.ɪks/
- Âm “sh” và “zh”: caution /ˈkɔːʃ(ə)n/, intentional /ɪnˈtɛnʃənəl/, anticipation /ænˌtɪs.əˈpeɪ.ʃən/, flush /ˈflʌʃ/, intentionally /ɪnˈtɛn(t)ʃənəli/
- Từ dài — đặt trọng âm cho đúng: violently /ˈvaɪ(ə)ləntli/, capability /ˌkeɪ.pəˈbɪl.ɪ.ti/, aerodynamic /ˌɛəɹəʊdaɪˈnæmɪk/, afterburner /ˈæf.tɚˌbɚ.nɚ/, similarity /ˌsɪm.ɪˈlæɹ.ɪ.ti/
Những âm người Việt thường gặp khó:
- Cụm phụ âm cuối — đọc đủ từng âm, đừng nuốt âm cuối: thrust /θɹʌst/, variant /ˈvæɹi.ənt/, checklist /ˈt͡ʃɛklɪst/, stealth /stɛlθ/, descent /dəˈsɛnt/
- Âm /tʃ/, /dʒ/ và /ʒ/ — tiếng Việt không có, đừng đọc thành “ch” hay “gi”: actuate /ˈæktʃu.eɪt/, checklist /ˈt͡ʃɛklɪst/, arch /ɑɹt͡ʃ/, urgent /ˈɜː.d͡ʒənt/, scratch /skɹæt͡ʃ/
- Âm /æ/ — mở miệng rộng hơn âm “e”: variant /ˈvæɹi.ənt/, actuate /ˈæktʃu.eɪt/, backseater /ˈbækˌsitɚ/, strap /stɹæp/, altitude /ˈælt.ɪˌtjuːd/
Cách luyện với video này
- Nghe hết video một lần, chưa cần nói, và ghi lại những từ bạn chưa biết.
- Nói đuổi từng câu ở tốc độ bình thường, lặp lại mỗi câu đến khi nhịp của bạn khớp với người nói.
- Ghi âm giọng mình rồi so với bản gốc, chú ý các từ như eagle, radar, variant.
Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
