Russia's Su-57 Felon Stealth Fighter Program Has Been 'Crippled'

Western sanctions have severely hampered Russia’s ability to produce the Su-57 fifth-generation fighter, complicating the acquisition of critical high-tech components. Russia, however, has circumvented some of these challenges by obtaining dual-use goods, such as the Siemens KLE 360 CNC, which are vital for manufacturing the fighter jet.

 

What You Need to Know: Western sanctions have severely hampered Russia’s ability to produce the Su-57 fifth-generation fighter, complicating the acquisition of critical high-tech components. Russia, however, has circumvented some of these challenges by obtaining dual-use goods, such as the Siemens KLE 360 CNC, which are vital for manufacturing the fighter jet.

-Despite Russia's resourcefulness, only about 32 Su-57s have been built, and the production remains slow due to the difficulty in procuring modern avionics, radar systems, and advanced materials.

-Strengthening sanctions could further hinder Su-57 production, reducing its impact on the war in Ukraine.

Su-57 Fighter Production Problems 

Western sanctions against Russia, following Putin’s illegal invasion of Ukraine, have complicated the production of Russian weaponry, including the fifth-generation Su-57 fighter. Yet, Russia has proven resourceful, working around the sanctions to access high-tech equipment.

One intelligence report indicated that Mikropribor, a Russian manufacturer involved in the development of the Su-57, had “acquired equipment for automated workstations to aid in the calibration and laboratory testing of specialized devices like the MPPU-50,” this plays a role in the jet’s communications and radar systems, Bokyo Nikolov reported

While the MPPU-50 is not installed on the aircraft, the MPPU-50 is crucial for testing communications and radar systems, which enable the Su-57 to operate with the situational awareness befitting of a fifth-generation fighter.

The Russians are also believed to have accessed a German-made Siemens KLE 360 CNC on a contract that was signed in July 2022, after the invasion commenced, and after sanctions were implemented. The KLE 360 is a machine automation tool that is vital to the precise manufacture of something with pinpoint specifications, like a fifth-generation fighter, for example.

Building the Su-57

The Su-57 is Russia’s fifth-generation fighter. The Su-57 is understood to be advanced; perhaps not as advanced as American counterparts like the F-22 Raptor, but still featuring stealth technology, supercruise, and a sophisticated weapons control system. “[The Su-57] enhances Russia’s combat capabilities but also bolsters its geopolitical influence,” Nikolov wrote. “With its design geared towards air combat, ground target engagement, and intelligence gathering.”

Yet, only about thirty-two Su-57s have been built. Sanctions have made the procurement of modern avionics and radar systems, which incorporate high-tech components, more difficult.  

Stepping Around Sanctions

One method by which the Russians have been able to sidestep Western sanctions is finding dual-use goods. Dual-use goods are products with a civilian application, that can also have a military application. Essentially, dual-use goods are sold on the civilian market but can be used for military production.

The Siemens KLE 360 CNC is one prime example of a dual-use good. The machine is commonly found in automotive and medical settings, yet is vital for the production of a fighter aircraft.

However, “producing the Su-57 goes beyond just calibration machines and CNC equipment, Nikolov wrote. “It demands a range of high-tech components, such as radar systems and infrared sensors for tracking targets. Advanced composite materials are also essential to reduce weight and enhance the aircraft’s stealth capabilities.”

The West could choose to strengthen sanctions, further complicating Russia’s abilities to make their fifth-generation fighter. Russia’s production struggles are likely to continue, which makes it unlikely that the Su-57 will have a significant impact on the Russo-Ukraine War.

While the Su-57 may only be used sparingly in the ongoing conflict, the jet can be seen, albeit as a CGI rendition, in the new Top Gun film. During the scene’s finale, Tom Cruise and Miles Teller battle two Su-57s from the seats of an F-14 Tomcat. The scene is implausible but highly enjoyable.
