In a time when hypersonic weapons and autonomous drones dominate global discussions, Russia‘s announcement of a new cruise missile for its Su-57 stealth fighter prompts inquiries that go beyond the weapon’s technical details. On April 27, 2025, Russian state media released footage of an unnamed cruise missile, which was examined by former president Dmitry Medvedev at a military testing facility, indicating its potential integration with the Su-57, Russia’s most sophisticated fighter jet.
The Kremlin’s timing, set against a backdrop of ongoing geopolitical strife and internal issues, implies that this revelation serves not only to enhance military capabilities but also to project strength.
What implications does this new weapon hold for Russia’s strategic goals, and how does it align with the wider context of global airpower rivalry? The Su-57, referred to by its NATO designation ‘Felon,’ represents Russia’s effort to introduce a fifth-generation stealth fighter that can rival Western models such as the U.S. F-35 Lightning II and F-22 Raptor.
Developed by Sukhoi, the Su-57 made its inaugural flight in 2010 and began limited operations with the Russian Aerospace Forces in 2020. It is engineered for air superiority, ground attack, and reconnaissance missions, featuring cutting-edge avionics, supercruise capability, and a minimized radar cross-section.
The aircraft’s dimensions include a length of approximately 20 meters and a wingspan of 14 meters, powered by two Saturn AL-41F1 engines, with future upgrades planned to the more advanced Izdeliye-30 engines for enhanced thrust and efficiency.
The Su-57 features internal weapon bays essential for its stealth capabilities, allowing it to carry various air-to-air and air-to-ground munitions, such as the K-77M missile for aircraft engagement and the Kh-69 cruise missile for precision attacks. However, the program has encountered significant obstacles, resulting in only a limited number of operational aircraft due to high expenses, technical difficulties, and Western sanctions affecting component availability.
A new cruise missile, briefly shown in footage reported by The Mirror, remains largely unknown. Russian officials have not disclosed specific details about its capabilities, but analysts have noted its visual resemblance to the Kh-101 cruise missile, a long-range weapon widely used in Ukraine.
War analyst Kirill Fyodorov, cited in the same report, pointed out that while the missile’s tail unit resembles the Kh-101, it appears different, indicating it could be a new design or a modified prototype. The Mirror also reported that the missile is equipped with a jet engine and an ‘enhanced warhead,’ although these assertions lack independent confirmation.
Given the Su-57’s design, the missile is likely intended for internal storage to maintain the aircraft’s stealth features, which are crucial for operating in contested airspace. In contrast to the Kh-101, which is generally launched from strategic bombers like the Tu-95, this new missile would need to fit within the Su-57’s limited weapon bays, suggesting it may be smaller or have a folding-wing design.
To grasp the importance of this development, it is essential to consider the Su-57’s position in Russia’s military strategy. Unlike the U.S., which has deployed hundreds of F-35s across various allied nations, Russia’s Su-57 fleet is relatively small, with estimates indicating fewer than 20 operational aircraft by early 2025. Production delays have been worsened by sanctions that have hindered access to foreign components, including microelectronics that were previously obtained from countries like Japan and Ukraine.
The announcement’s timing, occurring shortly after a surge in Russian missile strikes in Ukraine, introduces additional complexity. According to a report by The New York Times on April 28, 2025, there has been a notable increase in Russian missile and drone assaults in recent weeks, targeting Ukrainian cities such as Kharkiv and Sumy, despite ongoing U.S.-led peace negotiations. The introduction of a new weapon during this time may be seen as a message to both domestic and international audiences.
For domestic viewers, it strengthens the Kremlin’s portrayal of military might, countering critiques regarding Russia’s economic difficulties and setbacks on the battlefield. On the international stage, it highlights Russia’s capacity to exert influence, especially in light of NATO’s growing presence in Eastern Europe.
A comparison of the Su-57’s new missile with Western counterparts sheds further light on the situation. The U.S. utilizes the AGM-158 JASSM-ER, a stealthy cruise missile with a range exceeding 600 miles, launched from aircraft such as the F-15E Strike Eagle and B-2 Spirit. The precision and low-observable characteristics of the JASSM-ER set a standard for contemporary air-launched munitions.
Likewise, the UK and France deploy the Storm Shadow/SCALP missile, which has been effectively utilized by Ukrainian forces against Russian positions. Both systems benefit from established production lines and extensive combat experience, advantages that Russia’s new missile may not possess.
If the new missile is indeed a variant of the Kh-101, it could have a range nearing 1,500 miles, but its effectiveness would hinge on guidance systems and countermeasures, areas where Russia has traditionally fallen short compared to Western rivals. The development history of the Su-57 provides further context; initiated in the early 2000s as part of Russia’s PAK FA program, the aircraft was designed to succeed aging Soviet-era fighters like the Su-27 and MiG-29.
While its stealth features are advanced for Russia, they are regarded as less effective than those of the F-35, which benefits from a more sophisticated low-observable design and sensor capabilities.
The N036 Byelka radar on the Su-57 utilizes active electronically scanned array technology; however, its effectiveness against contemporary electronic warfare systems has yet to be validated. The aircraft’s first operational use in Syria in 2018 was primarily symbolic, involving minimal combat, which raises concerns regarding its preparedness for intense conflicts. In contrast, the F-35 has proven its capabilities in various combat zones, including Iraq and Syria, and benefits from a strong logistical support system among NATO allies.
The human and financial aspects of the Su-57 program are also significant. Russian engineers and designers, constrained by a sanctioned economy, are under considerable pressure to produce advanced technology with limited resources. The Su-57’s high production cost, estimated between $40-50 million per unit, places additional strain on Russia’s defense budget, which also needs to fund ongoing operations in Ukraine and the modernization of other military sectors.
If the new missile advances beyond the prototype phase, it will likely encounter similar obstacles. The development of a new weapon system necessitates thorough testing and integration, processes that could extend over several years given the current economic climate. The Kremlin’s choice to announce the missile prior to completing such testing indicates a strategic consideration: the announcement may hold more significance than the weapon’s immediate operational effectiveness.
Caution is advisable when assessing Russia’s assertions regarding its new missile, as the Kremlin has a track record of overstating its military capabilities, exemplified by the Kinzhal hypersonic missile, which was claimed to be ‘invincible’ but has been intercepted by Ukrainian air defenses.
The absence of comprehensive details regarding the new cruise missile, along with its limited showcase in controlled footage, suggests it may be a mockup or an early prototype instead of a finalized product. The Mirror’s report highlighted speculation that the missile might not be operational yet, a sentiment supported by analysts who doubt Russia’s capacity to swiftly develop new systems amid sanctions.
In the absence of independent verification of successful tests, the missile’s capabilities remain uncertain, and its compatibility with the Su-57—an aircraft still facing technical difficulties—adds to the ambiguity. The geopolitical ramifications of this announcement reach beyond Russia. The Su-57 has garnered interest from potential export markets, including India, which initially collaborated with Russia on the project but later withdrew due to concerns over cost and performance.
Other countries, such as Algeria and Turkey, have shown interest, but sales have been constrained by Russia’s limited production capacity. A new cruise missile could boost the Su-57’s attractiveness in the global market, especially for nations looking for cost-effective alternatives to Western systems.
However, competition from China’s J-20 and forthcoming sixth-generation fighters from the U.S. and Europe may overshadow Russia’s initiatives, particularly if the Su-57 does not fulfill its expected capabilities. Additionally, the broader context of Russia’s military modernization efforts is significant, as the Kremlin has made substantial investments in strategic weapons, including the Poseidon nuclear torpedo and the Burevestnik cruise missile, both of which have encountered developmental hurdles.
The Su-57 and its newly developed missile exemplify a trend of ambitious military projects aimed at demonstrating power, yet they frequently do not meet expectations. Although the Russian Aerospace Forces possess strengths in certain domains, they face challenges in pilot training, maintenance, and operational readiness, which could hinder the Su-57’s effectiveness, even if the missile is successful. In contrast, the U.S. Air Force benefits from a vast network of bases and allies, allowing it to deploy fifth-generation fighters more effectively.
Historically, Russia’s focus on advanced fighter jets and precision munitions has stemmed from a desire to equal or exceed Western military capabilities. During the Cold War, Soviet aircraft such as the MiG-25 and Su-27 posed significant challenges to U.S. supremacy, often compelling NATO to revise its strategies. The Su-57 carries on this legacy, yet the current global security landscape has evolved.
Asymmetric threats, cyber warfare, and unmanned systems are increasingly influencing modern warfare, prompting a reevaluation of the necessity for costly manned fighters. Russia’s choice to focus on the Su-57 and its new missile may indicate a dedication to conventional airpower, but it also risks reallocating resources away from urgent priorities, such as addressing drone swarms or enhancing electronic warfare capabilities.
Furthermore, the introduction of the new missile coincides with ongoing discussions regarding arms control and escalation, as evidenced by Russia’s concerns over Western missile provisions to Ukraine, including Germany’s potential supply of Taurus cruise missiles, highlighting the delicate nature of long-range strike systems.
On April 17, 2025, Reuters reported that Maria Zakharova, spokesperson for the Russian Foreign Ministry, warned that such arms deliveries could implicate Germany directly in the Ukraine conflict. The introduction of a new Russian missile may serve as a reaction to these events, indicating that Moscow still possesses the capability to respond with sophisticated weaponry. This reciprocal dynamic complicates the efforts to reduce tensions, especially as ceasefire negotiations stall.
The importance of Russia’s new cruise missile and its compatibility with the Su-57 extends beyond its technical specifications; it also reflects Moscow’s strategic priorities. The Kremlin’s choice to showcase this weapon amid economic difficulties and challenges on the battlefield indicates a deliberate attempt to influence perceptions both domestically and internationally.
Should the missile fulfill its potential, it could enhance the Su-57’s effectiveness in regional conflicts and strengthen Russia’s standing in the global arms market. Conversely, if it turns out to be another exaggerated initiative, it may deepen skepticism regarding Russia’s competitiveness against Western technology.
As the international community observes Russia’s forthcoming actions, a critical question remains: is the new missile for the Su-57 a true transformative advancement, or simply a reflection of aspirations limited by practical constraints?
