Russia’s Su-57 jet upgraded with advanced “co-pilot” AI system Showcased at LIMA 2025

Russia’s fifth-generation stealth fighter, the Sukhoi Su-57, may soon gain a powerful force multiplier in the form of the S-70 Okhotnik unmanned aerial system (UAS). Designed to function as a “loyal wingman,” the Okhotnik is expected to enhance the Su-57’s combat capabilities, especially with the integration of an onboard artificial intelligence (AI) co-pilot system. This advanced AI feature—developed by the United Aircraft Corporation (UAC)—was showcased at the Langkawi International Maritime and Aerospace (LIMA) Exhibition 2025 in Malaysia from May 20-24.

According to a report by the defence intelligence firm Janes, as cited by National Interest, the AI system will be incorporated into export variants of the Su-57. A Rosoboronexport representative—the Russian state agency overseeing military exports—confirmed to the firm that the AI is intended to support pilots during both routine and combat operations. Though exact technical specifications remain under wraps, it has been officially stated that the AI module will be offered as part of the Su-57’s export configuration.

UAC claims that the AI-assisted flight system acts as a virtual second pilot in the cockpit of the single-seat multirole fighter. The system is designed to handle various in-flight tasks, including identifying threats, managing navigational waypoints, and maintaining aircraft systems. This allows the human pilot to concentrate on higher-level mission objectives such as threat engagement and weapons deployment.

“The system is built to assist pilots by taking over routine operational functions, leaving the critical decision-making—like weapons release—under full human control,” the Rosoboronexport official told Janes. Additionally, the AI is said to be customizable to fit pilot experience levels. Veteran aviators may rely less on the system, while newer pilots could benefit from more comprehensive AI support.

“The system is flexible. It can adapt based on the needs and skill levels of individual pilots,” the UAC source added, highlighting its potential utility in both training environments and high-stakes combat scenarios.

However, the article points out that the AI upgrade also raises concerns. While the AI-assisted co-pilot has been part of the Su-57’s concept from early development stages, it’s unclear how the platform’s software and hardware have evolved to match recent breakthroughs in machine learning, large language models, and generative AI. Comparisons with the Lockheed Martin F-35 Lightning II—the most advanced fifth-generation fighter currently in service—underscore this point. The F-35 has faced major delays and issues due to its Technology Refresh-3 (TR-3) update, which required a complete overhaul of its hardware and software.

Given the heavy sanctions imposed on Russia and limited access to Western technology, questions linger about whether Moscow can maintain or upgrade its AI systems to remain competitive. Without access to cutting-edge microelectronics or AI research infrastructure, sustaining a next-gen AI-enabled flight system could prove extremely challenging.

At LIMA 2025, Rosoboronexport presented the Su-57E, the export version of the fighter, aiming to attract interest from regional air forces including Malaysia and other Southeast Asian nations. The aircraft has also been exhibited in Egypt, China, and India, though no confirmed foreign orders have materialized.

In a statement to Russia’s TASS news agency, Rosoboronexport emphasized the Su-57E’s performance in actual combat, citing its ability to operate effectively against advanced enemy air defences, electronic warfare systems, and AI-enabled aerial threats.

“The Su-57E stands out among a small group of fifth-generation rivals due to its successful performance in real-world combat scenarios,” Rosoboronexport noted, positioning the fighter’s AI integration as a potential game-changer for export sales.

By emphasizing the AI capabilities of the Su-57E in Malaysia, the article notes that UAC and Rosoboronexport hope to finally attract buyers.
