What You Need to Know: Russia's 5th-generation Sukhoi Su-57 Felon fighter jet faces significant challenges in combat and production. Despite a successful missile strike against Ukraine in February 2024, recent reports indicate setbacks, including damage from Ukrainian drone strikes and production delays caused by Western sanctions.

-These sanctions have disrupted critical components, such as Germany's WA36 attenuator, essential for the Su-57's communication systems.

-With only 10 units currently in service, and 75 more on order, the Su-57 program’s future remains uncertain as Russia struggles to maintain its high-tech fleet under mounting logistical and combat pressures.

The Su-57 Felon Stealth Fighter, Explained: 

Merriam-Webster’s Law Dictionary gives the etymology (that’s word origin) of “felon” as “Middle English, from Anglo-French felun, fel evildoer, probably of Germanic origin; akin to Old High German fillen to beat, whip, fel skin.” So then, given the felonious nature of Vladimir Putin’s seemingly never-ending “special military operation” in Ukraine (gotta love that officious euphemism, eh), perhaps it’s apropos that Russia’s most prestigious and high-tech (on-paper, at least) 5th Generation fighter jet, the Sukhoi Su-57, has been assigned the NATO reporting name “Felon.”

Sukhoi Su-57 early history & specifications

The Sukhoi Su-57 made its maiden flight on 29 January 2010 – a whopping eight years after it initially entered the development phase(!) – but didn’t officially enter into operational service with the Russian Aerospace Forces until Christmas Day 2020. The warbird is manufactured by the PJSC United Aircraft Corporation, headquartered at Leningradsky Avenue, Khoroshyovsky District, Moscow. According to the World Directory of Modern Military Aircraft (WDMMA), the Russian Air Force uses current year figures to have ten Su-57s in service, with an additional 75 supposedly on order. (So far, none have been allocated for Russian Naval Aviation.)

The Felon has the following specifications:

Wingspan: 14.1 m (46 ft 3 in)

Su-57 Status Report I: Inauspicious Combat Debut

So, back to what I was saying about the Su-57 not being in terribly good standing thus far…its combat performance thus far has been, to paraphrase Shakespeare, “Much ado about very little.”

Now, for the sake of fairness & balance, it should be noted that back on 18 February 2024, a Su-57, escorted by a pair of Su-35 Flanker-E/M fighters, launched a successful missile strike against Ukrainian ground targets using a Kh-69 cruise missile, and safely returned to base (RTB, to use a popular military aviators’ acronym). In addition, earlier this month, in an ironic case of intentional “friendly fire” (AKA “blue-on-blue” incident), a Felon used an air-to-air missile to deliberately shoot down an errant Russian-owned Sukhoi (yet more irony right there) S-70 Okhotnik-B drone over Ukraine about 10 miles (16 km) behind Ukrainian lines!

On the other hand, Ukrainian forces scored a major propaganda victory – and the accompanying prestige points – apparently damaged at least one –and possibly two – of the Felons on the ground at the 929th VP Chkalova State Flight Test Centre in Akhtubinsk (approximately 370 miles [595.4 km]) from Ukrainian-held territory, in an attack  reportedly carried out by three one-way attack (OWA) drones. Though admittedly, official claims from Defense Intelligence Directorate of Ukraine (GUR) should be taken with a grain of salt, the GUR evidently has some satellite imagery to back up this particular claim. According to CNN’s Brad Lendon:

“The agency posted satellite pictures in a post on its Telegram channel to support its claim, writing, ‘The images show that on June 7, Su-57 was still intact, but on June 8, craters from the explosion and distinctive fire spots emerged near it as a result of the fire damage.’”

Su-57 Status Report Part Deux: Trouble in (Production) Paradise)

As if that weren’t enough of a black eye for the Su-57 program, there’s also this from RBC-Ukraine:

“Russia has suspended production of Su-57 Felon fighter jets, with Western sanctions being the primary reason, despite Russia's attempts to circumvent them, citing The Telegraph…After reviewing Russian documents, Frontelligence Insight identified several key bottlenecks, including the WA36 attenuator (an electronic device that reduces signal amplitude or power without significantly distorting its shape, - ed.) and power supplies. These components are part of the MPPU-50, a German device used to calibrate the communication system of the Su-57.”

This would be just the latest addition to a litany of once-vaunted Russian-made weapons systems with less-than-stellar performance records in the real world. Time will tell what the future holds for the flying Felon.
