The U.S Air Force has tested an air-breathing
hypersonic engine whose thrust production
beat all the previous engines of this type.
The Air Force Research Laboratory ( AFRL)
announced this on on Aug 5, 2019, but did
not disclose when the test was carried out.
The scramjet engine is developed by Northrop
Grumman for AFRL.
Pat Nolan, Northrop Grumman’s Vice President
for Missile Products said in a statement.
“The series of tests on this fighter-engine
sized scramjet was truly remarkable.
The scramjet successfully ran across a range
of hypersonic Mach numbers for unprecedented
run times, demonstrating that our technology
is leading the way in delivering large scale
hypersonic platforms to our warfighters.”
This is an important development since the
U.S military is actively pursuing hypersonic
technology and is virtually in a race with
Russia & China in this sector.
In this video Defense Updates reports on the
successful test of highest thrust producing
hypersonic scramjet engine by the U.S.
Let’s get started.

An object is said to be hypersonic once they
exceed speeds of Mach 5 that is 5 times the
speed of sound.
This is about 1,715 meters per second or 3,836
mph or 6,174 km/h.
There are currently two methods being applied
to make hypersonic weapons.
First is using Hypersonic Glide Vehicle (HGV).
In this method, the system is launched to
extremely high altitudes using Ballistic Missile
or an aircraft where it skips across the Earth’s
upper atmosphere.
The vehicle then separates from the carrier
and the scramjet engine takes over, accelerating
it to hypersonic speeds as it glides back
to the earth towards its intended target.
Second is using a Scramjet engine.
The scramjet is an innovation on the Ramjet.
Ramjet engine can power flight to supersonic
speeds but scramjet can enable the missiles
to reach hypersonic speeds.
These engines have no moving parts, like the
compressors and turbines used in the turbofan
engines found on conventional jet planes.
They rely on the huge pressures created by
fast airflow into the engine to ignite the
fuel and generate thrust.
In this method, a rocket booster is used to
accelerate the missile to hypersonic speed,
then the scramjet engine kicks in and enable
the missile to fly at sustained hypersonic speed.
The latest test is using scramjet methodology.
As per reports, Air Force Research Laboratory
and Northrop Grumman have tested an 18-foot
long fighter-engine sized scramjet engine.
The test has been carried out for 9 months
and was conducted at the Arnold Engineering
Development Complex’s (AEDC) Aerodynamic and
Propulsion Test Unit at Arnold Air Force Base
in Tennessee.
The engine ran for a total of 30 minutes across
an unspecified number of tests and was able
to generate up to 13,000 pounds of thrust
under conditions in which it will experience
speeds of above 4 Mach.
It is important to note that the Air Force’s
statement described the engine running at
‘conditions above Mach 4’, though as explained
earlier – speed is considered hypersonic when
it is 5 Mach and above.
So, we can assume that during the whole tenure
of testing, some tests were carried out to
replicate conditions of 5 Mach and above.
Viewers may note that the 18-foot hypersonic
engine is similar in size to fighter jet engines
and 13,000 pounds of thrust is much less compared
to traditional once.
For example, 16 ft 11 inch Pratt & Whitney
F119 engine used in F 22 Raptor produces 35,000
pounds of thrust.
So on paper, the test seems to be nothing
But the fact is that the scramjet engine is
designed to generate the thrust in extremely
high altitude where the air is much thinner
and the conditions are extremely harsh.
The engine, if used in conditions similar
to cruise altitude of a typical fighter jet
will exceed the performance of current crop
of jet engines.
To give the viewer a perspective, so that
the real stature of the achievement can be
gauged, we can compare it with the Boeing’s
X-51A Waverider hypersonic test.
SJY61 engine which powered the Waverider and
was being tested by AFRL between 2005 and
2013, produced a maximum of 1,000 pounds of
Countries like Russia, China, and the U.S
have been developing sophisticated layered
air defense.
These systems are difficult for traditional
aircraft & missiles to penetrate.
For example, Russia has deployed S 400 air
defense system.
S 400 Triumph is an anti-aircraft weapon system
developed by Russia’s Almaz Central Design
Bureau in the 1990s as an upgrade of the S
300 family.
it has been in service with the Russian armed
forces since 2007.
It is designed to defend against aircraft
including 5th generation stealth fighters,
bombers, AWACS, cruise missiles, and even
ballistic missile.
S 400 can track hundreds of target at a time,
engage up to 36 targets in parallel and simultaneously
launch 72 missiles.
Russia is also working on S 500 which will
be even more potent.
U.S fields several systems that are designed
to intercept ballistic as well as cruise missiles
like THAAD or Terminal High Altitude Area
Defense which is designed to shoot down short,
medium, and intermediate-range ballistic missiles
in their terminal phase.
US Navy also has a large number of Ticonderoga
class and Arleigh burke class warships which
have the Aegis combat system
Aegis Ballistic Missile Defense which is part
of the Aegis combat system is devised to intercept
ballistic missiles post-boost phase and before reentry.
It uses Standard Missile like SM3, SM6 to
shoot down incoming threats.
On the surface, missile defense looks like
a defensive weaponry but it can disturb the
MAD equilibrium.
Mutually assured destruction (MAD) is a doctrine
of military strategy and national security
policy in which a full-scale use of nuclear
weapons by two or more opposing sides would
cause the complete annihilation of both the
attacker and the defender.
It is based on the theory of deterrence, which
holds that the threat of using strong weapons
against the enemy prevents the enemy’s use
of those same weapons.
This balance will be disturbed if any country
is able to field a fully functional missile
defense system that can defend against the
enemy’s missile.
This is where hypersonic weapons come in.
Their extreme speed and ability to fly in
unpredictable path give them a high probability
of penetrating the air defenses.
They will be very hard to track, let alone
It is to be noted that traditional ballistic
missiles also reach hypersonic speed when
then descend on the target but they follow
a predictable predefined parabolic path which
could lead to possible interception by anti-ballistic
missile defense systems.
The characteristic of Hypersonic weapons makes
it suitable for neutralizing well-defended
strategic military assets.
These weapons may also have used in neutralizing
incoming enemy missiles, where they will be
used as interceptors.
Russia is leading the hypersonic weapons space
It has claimed that it has already fielded
a Scramjet engine based hypersonic missile
named Kinzhal and is very close to having
an operational hypersonic boost-glide vehicle
named Avangard.
The Kinzhal or Dagger was one of the weapons
the Russian president Vladimir Putin unveiled
in his ‘state of the nation’ address last
Kinzhal reportedly has a range of approximately
1,250 miles or 2000 km and a top speed Mach
10, that is more than 10 times the speed of
According to the Russian president, units
in the country’s Southern Military District,
which borders Ukraine and the Black Sea, have
deployed the missiles operationally.
China is thought to be pursuing hypersonic
weapons as well and has made some progress
with Hypersonic Glide Vehicle (HGV) approach.
The United States is working on both the approaches
for developing its hypersonic weapons and
may have different working prototypes by 2021.
It is evident that hypersonic weapons will
be one area that will see a lot of work in
coming days and the nation that will be able
to operational deploy hypersonic weapons on
different platforms will have an edge in future


  1. Nice work. Now all we have to do is quit getting our shit stolen so we don't have to play catch up to our own tech again.

    Also elect less Democrats.

  2. At last. USA has finally awaken! You have become complacent, thinking no one was better or the brains! Well you want to BE GREAT AGAIN. THEN GET RID OF YOUR BIGGEST DRAWBACK , FOR IT IS THAT MORON WHO THINKS HEs King! vote in a Proper Mr PRESIDENT and take ALL the people with him, you will GREAT.

  3. we getting there we still playing catch up with Russia, and China but its good to see we have woke up now our model will be better than thiers

  4. M.A.D. balance will be maintained unless one side can shoot down ALL of the enemies incoming missiles…miss a few dozen out of thousands and OOPS!! [also prepare for incoming second and third wave barrages from submarines]

  5. Who had the first air launched missile?? When was it deployed?
    Give up??
    It was the Phoenix missile, used on the F-14 TomCat. It was deployed in 1974. The Phoenix went mach 5!!
    America is no stranger to hypersonic missiles. If the Phoenix was updated with modern electronics and avionics, it would be awesome. With the Phoenix, the F-14 was able to target and destroy 6 enemy planes simultaneously.

  6. So this is why Russia made fake news to try to stay ahead of everybody but the nuclear explosion says otherwise from what people are saying so far

  7. No! they are letting you think they are. just remember your russian history of the past. ALL A BLUFF. until they actually caught up! Silly people. Just concentrate on your own toys ..

  8. This "hypersonic gap" is like the "missile gap" and "bomber gap" that came before.
    It is BS, and an excuse to throw more money at the Pentagon.
    The Phoenix went mach 5, and it was deployed in 1974.
    The US knows a lot about hypersonic missiles, and can design and build them almost instantaneously.
    PLUS, these new missiles that Russia and China CLAIM to have, are both unproven and expensive. Russia has no money to build them in useful quantity. And China's build quality has been lousy. Mostly, their products have not lived up to hype.

  9. More on the Phoenix. Mach 5, true. But, also outdated. Its ancient avionics could be defeated by AEW, thus causing them to miss. That is main reason it was dropped.
    Just going Mach 5 does not mean a successful missile. It also needs modern avionics that can defeat jamming and AEW. Do the Russian and Chinese missiles succeed in that?
    Can they defeat laser defenses, which our Navy will soon have???

  10. I thought American YouTube generals said US doesn't need hypersonic missiles because lasers travel at the speed of light?

  11. The Russians just recently had a nuclear powered Cruise missle, that blew up in testing, killing Five people and irradiated the whole area! THEY have hypersonics galore πŸ€”πŸ€ͺπŸ˜΅πŸ˜πŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡ΈπŸ‡¬πŸ‡§πŸ‡¬πŸ‡§πŸ‡¨πŸ‡¦πŸ‡¨πŸ‡¦πŸ‘

  12. Not fast enough, because Russia is already producing hypo missiles. Kinzel Is one example. Play catch-up.πŸ˜‚

  13. " And the scramjet engine takes over, accelerating it to hypersonic speeds as it glides back to earth" ………… The word " glide " means un powered flight. can't glide when using thrust. what else does this channel get wrong?

  14. America has had top secret hypersonic stealth missiles since the late 90s. They’ve just never been declassified or ever will be since they were direct violations of certain treaties. The fact Russia is building a nuclear version of the same concept so it can indefinitely loiter or use very unusual and off course vectors is about the only difference. Here’s the rub, the US has had a chance to put geostationary radar arrays that use the same tech as the f22 radar in orbit that can filter through ground clutter by using a variety of methods. Most of these tend to be over the North Pole, they’d probably have to invest in putting some around the continental US to counter khinzal

  15. Like i said…russia might have a head start, but the US will catch up fast, because they have the technologies and money to produce it and mass produce it.


  17. Is the US truly playing catch-up "in this sector"? I honestly doubt it but no matter: git 'er done!!! Great video BTW…

  18. usa is in a race with russia…..what a joke….Russia has already started to produce Kinzhal and Avandgard missiles….usa is 2 generations behind Russia in missile technology!!!! and it is worth to mention usa has 22 trillion dollars debt! their days are numberd!!! Slava Rusiji!

  19. Finally a true scramjet engine being made by the best! Russia cant even keep their "nuclear powered cruise missile" in the air or keep it from killing their own people and contaminating the area with radiation. So far Russia is only good at nuking themselves.πŸ˜‚πŸ˜‚

    USA! USA! USA! πŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡Έ

  20. USA Flys manned hypersonic aircraft X15 πŸ‘
    And at least USA has a real not animated 20 year old video flying and Launching a hypersonic missile from a B52 unlike Russia /Propaganda animated CGI 🀣

  21. Why do we keep getting these completely meaningless propaganda videos that are so poor you must believe it's a 15-year-old.
    The Avangard (Russian: Авангард), previously known as Objekt 4202, Yu-71 and Yu-74, is a Russian hypersonic glide vehicle (HGV), that can be carried as a MIRV payload by the UR-100UTTKh, R-36M2 and RS-28 Sarmat heavy ICBMs. It can deliver both nuclear and conventional payloads.
    The US has nothing anywhere near this technology. The US is still to produce a hypersonic weapon of any kind. The 15-year-old who makes these videos seems to think the US can click its fingers and just magic in modern hardware.

  22. In all honesty, MAD won't be disturbed with missile defense, instead it will continue to be a new theoretical arms race

  23. Did the world just think we will sit idly by while they develop advanced weapons? God bless the United States even though we've turned our back on God you still buses us with Liberty Power and justice around the world

  24. God bless America,only the enemies will find out the true blunt force of the American military might,many countries have learnt that the hard way.πŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡ΈπŸ‡ΊπŸ‡Έ

  25. Look, America has one super weapon and only one – the American way of life. This weapons has already conquered the planet. America won. Game over. E.G this video is sponsored by war thunder? Last time I've checked, Gaijin's HQ is in Moscow. Basically everyone loves the USA and NOT because of its weapons or because of its army, because it is the place were modern democracy was born. Because of freedom. Because of secularism. Because this is the only place in the world where you can give the middle finger to anyone who thinks your way of life doesn't fit his ideas of "the proper way of life". Because of love. And that is why, gentlemen, America had already won. PS the right to own and carry firearms – is perhaps the most ingenious thing in the American way of life. E.G Putin would have been shot and killed at least a dozen times, had he tried to take over America and not Russia.

  26. As the US should. Also, it was only a matter of time. Moreover, with the amount of research and development that is taking place in that field, coupled with the high defense budget, the US is bound to come up with some highly sophisticated equipment and technology that will propel them in the hypersonic weapons field.

  27. none of this matters as long as china gets to steal whatever they want. All of our advanced tech means nothing when the blue prints are hacked….Still think this is a very cheap and boring way to make a video….if you don't want to have more then 1 picture a minute how about just keep the back ground black?

    You are leaving people with more questions then you gave answers too….are you trying to be boring?

  28. They better, they're playing catchup. While the US military was targeting funeral processions and wedding parties for 18 years, the world moved into the 21st century. India has hypersonic missiles, ffs. The Indians! We don't. Shame. (Ding) Shame. (Ding) Shame…

  29. Conventional Warfare has been rendered obsolete by unconventional War tactics. If the greatest military in the world can't beat a bunch of guys hiding out with AK-47s in Mountain caves my point is proven. Any military not able to stand up and fight in open battle will resort to unconventional War tactics rendering conventional War obsolete because it's unwinnable using those standard tactics
