Russia is quietly developing a new ultra-light launch vehicle called the Voronezh, but the real story lies deeper—in the powerful and highly adaptive NK-3 engine being built by ODK-Kuznetsov.
In this video, we break down everything you need to know about the NK-3: from its modular design and multi-plane thrust vector control to its environmentally cleaner fuel system. With 13 engines powering a single rocket, this is a bold engineering approach aimed at flexibility, redundancy, and precision.
We also explore how the Voronezh rocket compares to established systems like Soyuz-2 and Angara-1.2, and why Russia is shifting toward smaller, faster, and more responsive launch solutions for satellite constellations.
With NK-3 testing planned for 2027 and a first launch targeted for 2029, the stakes are high. Russia’s private space sector has struggled in the past—but could this engine finally change everything?
Watch till the end to understand why NK-3 might be the most important Russian engine you’ve never heard of—and what it means for the future of space launches.

The Voronezh, Russia's next-generation
0:08
ultra-light launch vehicle, is not only
0:10
a conceptual project, but also a
0:12
technological pathway to more flexible,
0:15
cost-effective, and rapid access to low
0:18
Earth orbit.
0:19
Although the rocket's size, payload, and
0:22
cost have been the main subjects of
0:24
initial discussion,
0:25
the NK-3 engine, a domestically
0:28
researched propulsion system, is the
0:30
real focal point of this program.
0:33
Its success or failure may determine the
0:35
fate of the entire initiative.
0:38
What makes this even more interesting is
0:40
how the Voronezh project reflects a
0:42
deeper shift in Russian space strategy.
0:46
It marks a transition from launching
0:48
massive, multi-ton payloads to deploying
0:51
smaller satellites in a more agile and
0:53
responsive way.
0:55
This aligns with global trends, but
0:57
Russia's approach stands out because of
1:00
its reliance on a new generation of
1:02
compact, environmentally conscious
1:04
engines developed by its historic
1:06
manufacturer.
1:07
As Altitude Addicts would put it, this
1:10
is not just evolution, it's a strategic
1:12
reset in how access to space is being
1:14
redefined.
1:16
To understand this transformation, we
1:19
need to look at the origins of the NK-3
1:21
engine and how it builds upon a legacy
1:24
of Soviet engineering excellence.
1:27
The NK series engines have long been
1:29
associated with major aerospace
1:31
achievements, with earlier variants,
1:33
such as the NK-33, gaining global
1:36
recognition for their efficiency and
1:38
reliability.
1:39
However, the NK-3 is not a revival of an
1:42
old design.
1:43
It is a completely new engine,
1:45
purpose-built to meet the demands of
1:47
ultra-light launch vehicles.
1:50
Development of the NK-3 began in 2023 as
1:54
part of the Voronezh program.
1:56
By early 2026, engineers were already
2:00
working on multiple configurations of
2:02
the engine.
2:03
Unlike older designs optimized for heavy
2:06
rockets, the NK-3 is being created for
2:08
modular deployment.
2:10
The Voronezh rocket itself will use a
2:12
total of 13 engines, with 12 clustered
2:15
on the first stage and a single engine
2:18
powering the second stage.
2:20
This clustering approach introduces
2:22
several advantages.
2:24
It allows redundancy, scalability, and
2:27
highly precise thrust control,
2:29
especially when combined with advanced
2:31
vectoring systems.
2:33
The NK-3 will feature multi-plane thrust
2:35
vector control, enabling the rocket to
2:38
adjust its trajectory dynamically during
2:40
flight.
2:42
This level of control is critical for
2:44
accurate orbital insertion and mission
2:46
flexibility.
2:48
Moving deeper into the engineering
2:50
philosophy behind the NK-3, one of its
2:53
most notable features is its focus on
2:55
cleaner fuel.
2:57
While exact propellant details remain
2:59
undisclosed, officials emphasize that
3:02
the engine is designed to reduce
3:03
environmental impact, especially at
3:06
launch sites like Vostochny.
3:09
This represents a clear departure from
3:11
older Soviet-era systems that relied
3:13
heavily on toxic hypergolic fuels.
3:16
The cleaner combustion cycle of the NK-3
3:19
is expected to significantly reduce
3:21
stress on surrounding ecosystems.
3:24
This is becoming increasingly important
3:26
as modern space operations face growing
3:29
environmental scrutiny.
3:31
At the same time, adaptability remains a
3:34
key strength.
3:36
The engine is being developed in
3:37
multiple variants, potentially allowing
3:39
it to power not just Voronezh, but
3:41
future small launch systems as well.
3:45
As Altitude Addicts often highlight in
3:47
their deep dives, modularity like this
3:50
can define the long-term success of an
3:52
engine platform.
3:54
It opens the door to scalability, cost
3:57
reduction, and broader application
3:59
across different missions.
4:01
Despite its promise, the NK-3 is still
4:04
in the early stages of development.
4:07
Bench testing is scheduled to begin in
4:09
2027, with a flight-ready rocket
4:12
expected by 2029.
4:15
This timeline reflects both ambition and
4:17
risk.
4:19
As of 2026, the Voronezh rocket exists
4:22
partially as a second stage mock-up,
4:24
while its electronic systems are
4:26
undergoing independent testing.
4:29
The approval of its conceptual design
4:31
marks a major milestone, but significant
4:33
work remains.
4:35
Transitioning from concept to
4:37
operational system will require
4:39
extensive engineering, testing, and
4:41
validation.
4:43
Historically, this has been a
4:45
challenging phase for private aerospace
4:47
initiatives in Russia, where many
4:49
promising ideas have struggled to reach
4:52
commercial deployment.
4:54
Shifting focus back to the rocket
4:56
itself, the Voronezh serves as the
4:58
platform built around the NK-3 engine.
5:02
It is a two-stage ultra-light launch
5:04
vehicle with a length of around 20 m, a
5:07
diameter of approximately 2 m, and a
5:09
launch mass of about 35 tons.
5:13
Its payload capacity ranges between 330
5:16
and 400 kg to an orbit of 500 km.
5:22
This modest capacity is intentional.
5:25
The rocket is not designed to compete
5:26
with larger systems, but to fill a
5:29
specific niche, rapid deployment of
5:31
small satellites.
5:33
This capability is increasingly
5:35
important as satellite constellations
5:37
expand globally.
5:39
From a market perspective,
5:41
cost-efficiency becomes a defining
5:43
factor.
5:45
A single Voronezh launch is estimated at
5:47
around 700 million rubles, significantly
5:50
lower than larger launch vehicles.
5:53
However, the real advantage lies not in
5:55
raw capacity, but in flexibility and
5:58
speed.
5:59
Smaller rockets can be produced more
6:01
quickly, launched more frequently, and
6:04
prepared with shorter lead times.
6:07
This aligns perfectly with the needs of
6:09
modern satellite operators, who
6:11
increasingly prioritize responsiveness
6:13
over sheer payload size.
6:16
The involvement of private industry adds
6:19
another layer of complexity.
6:21
The Voronezh project is being developed
6:23
by a private company with funding
6:25
support, marking a departure from the
6:27
traditionally state-dominated Russian
6:30
space sector.
6:32
This brings both innovation and
6:34
uncertainty.
6:35
On one hand, private participation can
6:38
accelerate development and reduce costs.
6:41
On the other, it raises concerns about
6:43
long-term sustainability and execution.
6:47
As Altitude Addicts would carefully
6:48
note, the biggest challenge is not
6:51
designing a rocket, it's actually
6:53
delivering one that works reliably in
6:56
real-world conditions.
6:58
Looking ahead, the Voronezh rocket is
7:00
expected to launch from Vostochny
7:02
Cosmodrome.
7:04
However, it remains unclear whether
7:06
dedicated infrastructure will be built
7:09
for it in the near future.
7:11
This highlights a broader issue,
7:13
integrating new systems into existing
7:15
spaceport capabilities.
7:18
Ultimately, the future of this program
7:20
depends on one critical factor, the NK-3
7:23
engine.
7:24
The rocket may define the mission, but
7:27
the engine defines whether that mission
7:29
is even possible.
7:31
The coming years will be decisive.
7:34
With testing planned for 2027 and a
7:36
potential first flight in 2029, the NK-3
7:40
faces a tight schedule and high
7:42
expectations.
7:44
Success could mark a turning point for
7:46
Russia's private space ambitions.
7:49
Failure, however, would reinforce
7:51
long-standing doubts about the ability
7:54
to convert bold concepts into
7:55
operational systems.
7:58
For now, the NK-3 remains a promise, one
8:01
that could reshape Russia's access to
8:03
space or become another missed
8:05
opportunity in its complex aerospace
8:07
journey.
8:10
Today in Russia,
8:13
there are no missiles beyond the light
8:15
class in operation, respectively, there
8:17
are engines for them. But how does
8:20
Kuznetsov take part in the development
8:22
of superlift class launch vehicles? Our
8:25
company is developing a director.
8:29
For stage one and stage two, super
8:31
rockets allow small satellites to be
8:34
brought back into orbit with sufficient
8:36
accuracy.
8:39
The more accurate the payload will be,
8:42
the longer it will exist there today.
8:48
The sketch design stage for the engine
8:50
has been completed, that is, this work
8:52
will be completed in 2025,
8:55
and our team began the next stage, the
8:57
stage of developing working designs of
8:59
the documentation and the Voronezh
9:01
ultra-light rocket.
9:04
There are two stages at one stage to
9:06
supervise the use of 12 engines.
9:10
At the same time, four motors without
9:12
termination, without thrust vector
9:14
control, and peripheral eight motors,
9:17
they are with controlled thrust vector.
9:22
Two phases of development.
9:25
One use of one engine is provided.
9:28
With two-plane electronic thrust control
9:31
to reduce the development, product, and
9:33
testing time of new units, and the new
9:36
units we have are all automation units.
9:43
Flow regulator throw gas generator.
9:47
We plan to use additive technologies for
9:50
some of the products announced.
9:54
Well, similar, which was attached,
9:57
serves as the basis for creating our M23
10:00
engine, which you are an angle valve
10:02
shifting.
10:07
And he from men
10:10
from the best.
10:13
But
10:15
he better ask
10:18
twice the forest succeeded in the story.
10:20
So to speak, Dad, we are waiting for
10:23
this. By the way, we need to go to 17,
10:25
which is not visible here, but we are in
10:28
danger. So, I call it I spent a lot of
10:32
time sealing these three tools, and
10:34
that's it.
10:37
Let's discuss your recent strength
10:38
calculations and identifiable
10:40
concentration points.
10:44
There would be less savings in the end.
