Russia's Su-57 Fighter Has a New Enemy (No, Not the F-35 or F-22)
Western sanctions imposed after Russia's 2022 invasion of Ukraine are severely hindering the production of the Sukhoi Su-57 stealth fighter. Despite Moscow’s plan to double Su-57 production by 2028, leaked reports reveal that Russia is struggling to source crucial Western components needed for production.
And That Enemy's Name...Sanctions: Western sanctions imposed after Russia's 2022 invasion of Ukraine are severely hindering the production of the Sukhoi Su-57 stealth fighter. Despite Moscow’s plan to double Su-57 production by 2028, leaked reports reveal that Russia is struggling to source crucial Western components needed for production.
-These include calibration and radar systems, advanced machines like Siemens KLE 360, and composite materials such as carbon fiber.
-Russia has resorted to smuggling and sourcing restricted parts from countries like China and Kazakhstan.
-The situation illustrates the broader issue of dependence on international suppliers for military hardware, a lesson the U.S. aerospace and defense industry must also heed.
Sanctions Threaten Russia’s Su-57 Stealth Fighter Production
Western-imposed sanctions that went into effect after Russia launched its unprovoked invasion of Ukraine in February 2022 remain very much in place, and according to a recent report from Ukrainian open-source military analytics group Frontelligence Insight, it could impact the production of the Sukhoi Su-57 (NATO reporting name Felon).
The Kremlin has touted the fifth-generation stealth fighter as being on par with the U.S.-produced Lockheed Martin F-35 Lightning II. Yet, Moscow has struggled for years to build its Su-57 in significant numbers – even as it announced to double production through 2028.
Even before the latest sanctions were imposed in 2022, Russia had failed to reach serial production and scaled back on forecasts of how many might be produced.
The open source researchers have reported that the Su-57 program could be in a worse state than previously understood.
"After reviewing an internal correspondence leak from a Russian military electronics plant "Mikropribor", Frontelligence Insight, with data provided by @CyberResUa discovered that the production of the Su-57 is in jeopardy without access to crucial Western components," Tatarigami UA announced in a post on X, the social media platform formerly known as Twitter.
Dagens.com also reported last week, "leaked documents from Russian military electronics manufacturer Mikropribor, which supplies key components for the aircraft, indicate that the lack of several essential Western parts is becoming a major obstacle."
Russia Looking for Ways Around Sanctions for Su-57
Due to the ongoing sanctions, which almost certainly won't be lifted until the war is ended and possibly even long after that, Russia has gotten creative in trying to acquire the necessary components that could be used in the Su-57 production.
Bulgaria Military reported earlier this week that has included the "secret purchases of German equipment."
The specific components in question are MPPU-50 modules, which aren't actually installed in the aircraft. Rather the radar device is needed for the "calibration and testing of radar and satellite communication systems in military aviation." The modules help fine-tune and test the radar systems. Without that testing and calibration, the Su-57's radar may not work as desired or even at all.
In addition, the production of the stealth aircraft requires the Siemens KLE 360 CNC machine, an advanced lathe, as well as WA36 suppressors, and specific power supply units.
"Equipment like the MPPU-50 and machines such as the Siemens KLE 360 are invaluable to the Russian defense complex. They are integral to the development and verification of avionics, ensuring that modern aircraft can perform at their peak capabilities," Bulgaria Military explained.
Even in normal times, the international sale and transfer of such components are carefully maintained and monitored. But with the sanctions, Russia has had to turn to intermediaries, who have smuggled or sourced the restricted items from China and Kazakhstan.
"Considering that Russian military production continued to expand in 2023 and 2024, it's clear that they find ways to smuggle key components or purchase Chinese replacements to maintain production. While we can't eliminate these deliveries, we should aim to minimize them," Tatarigami UA noted.
The Frontelligence Insight analysts have called upon the West to find a way to minimize Russia's efforts. That could include closing loopholes on components that are sold as "dual-use" including in the production of automotive and medical devices. Efforts will need to be ramped up to close any loop holes that allow these components to continue to find a way to Russia.
Yet, though the calibration and CNC machines are vital in the Su-57's production, Russia still needs to source other components as well as the composite materials including carbon fiber. Russian industry simply isn't geared towards building everything that goes into the Su-57.
This is seriously impacting the Su-57's production and will likely continue.
A Lesson for America for F-35
The troubles Russia is facing in obtaining the components and materials should be a warning to the U.S. aerospace and defense sectors.
F-35 employs components from partner supplies spread out around the world, highlighting if the U.S. were to suddenly exit NATO or find itself going all in on an "America First" ideology, it could face similar issues – even without sanctions. The U.S. doesn't make all the components its military requires, and even if it could it doesn't have a source for all the materials – notably rare earth minerals.
More than 1,000 F-35s have been manufactured in no small part because the U.S. has strong partnerships in place, while Russia – which has no such international joint deals in place in its aerospace sector – has struggled to build more than two dozen Su-57s.
