In a significant development for unmanned combat air vehicles (UCAVs), Russia has introduced a new design concept for a ‘loyal wingman’-type drone, dubbed the Grom (meaning Thunder). This unveiling marks a critical step in Russia’s ongoing efforts to enhance its military capabilities in the realm of advanced drone warfare. The Grom, developed by the Kronshtadt company, made its debut at the Army 2024 defense exhibition, held in the Moscow region from August 12 to 14. Unlike many modern UCAVs that emphasize stealth and endurance, the new Grom design shifts the focus towards raw performance, particularly in the transonic realm. This article delves into the intricacies of the Grom’s design, its potential capabilities, and the broader implications for Russia’s military strategy.
The Evolution of the Grom Design
The Grom drone has undergone a notable transformation from its earlier iterations. The original Grom, first unveiled at the Army 2020 exhibition, bore a resemblance to other modern UCAVs, such as the Airbus Barracuda and the XQ-58 Valkyrie. The earlier design featured a more conventional UCAV configuration, prioritizing stealth and endurance. However, the new Grom design, showcased at Army 2024, represents a radical departure from this approach. The drone now resembles a Cold War-era tactical jet, with a cropped delta wing and a conventional tail section, complete with horizontal stabilizers and a vertical fin.
This shift in design philosophy reflects a change in priorities for Russian drone development. The new Grom appears to be optimized for high-speed performance and maneuverability, rather than low observability and endurance. The inclusion of features such as a fighter-style circular dilating exhaust nozzle, a trapezoidal-shaped air intake, and a streamlined forward fuselage further underscores this focus on performance. These design choices suggest that the Grom is intended to operate in high-threat environments, where speed and agility are more critical than stealth.
Technical Specifications and Capabilities
The Grom’s technical specifications highlight its emphasis on performance. Powered by a single turbofan engine, the drone is expected to achieve a maximum speed of 1,000 kilometers per hour (621 miles per hour) and a cruising speed of 650-800 kilometers per hour (404-497 miles per hour). The drone’s maximum altitude is reported to be 12,000 meters (39,370 feet), with a range of up to 700 kilometers (435 miles). These performance metrics position the Grom as a formidable asset in scenarios requiring rapid deployment and high-speed engagement.
The choice of engine for the Grom has been the subject of speculation. Some reports suggest that the drone may be powered by the AI-222-25 two-shaft turbofan used in the Yak-130 Mitten jet trainer. This engine, while not typically equipped with an afterburner, could be modified to include one, potentially enhancing the Grom’s speed and performance. Other accounts point to the possibility of the RD-33 or RD-93 engines, used in the MiG-29 Fulcrum and JF-17 Thunder, respectively, being selected for the Grom. These engines, which feature afterburning as standard, would align with the drone’s high-speed design.
In terms of armament, the Grom is designed to carry up to 2,000 kilograms (4,409 pounds) of munitions. This payload includes a variety of guided and unguided bombs and missiles, ranging from 100 to 500 kilograms (220 to 1,102 pounds). The drone’s internal weapons bay is likely optimized for high-speed operations, with additional provisions for underwing stores. The mockup displayed at Army 2024 was shown alongside the Kh-58UShK anti-radiation missile, a modernized version of the Cold War-era Kh-58. This suggests that the Grom is intended to engage in electronic warfare and suppression of enemy air defenses (SEAD) missions.
Kronshtadt envisions the Grom as a ‘loyal wingman’ drone, designed to operate in conjunction with manned aircraft. In this role, the Grom would serve as a force multiplier, augmenting the capabilities of crewed fighters such as the Su-35S Flanker and the Su-57 Felon. The drone’s missions would include detecting and attacking ground-based air defense systems, conducting reconnaissance (including electronic intelligence or ELINT), and striking land and sea targets, even beyond the front lines.
The concept of a ‘loyal wingman’ is not new, but the Grom represents a unique interpretation of this idea within the context of Russian military doctrine. The emphasis on speed and maneuverability suggests that the Grom is intended to operate in highly contested environments, where its agility could help it evade detection and countermeasures. This focus on performance over stealth may also reflect lessons learned from the ongoing conflict in Ukraine, where the ability to rapidly respond to threats has proven crucial.
The Grom’s design also hints at potential air-to-air capabilities, although this has not been explicitly confirmed by the manufacturer. The drone’s high-speed performance and potential for maneuverability could enable it to engage in aerial combat, providing an additional layer of defense for manned aircraft. This would represent a significant expansion of the traditional role of UCAVs, which have primarily been used for ground attack and reconnaissance missions.
Comparison with Other Russian UCAVs
The introduction of the Grom adds another dimension to Russia’s UCAV portfolio, which already includes the S-70 Okhotnik-B, or Hunter-B, a flying wing UCAV designed to operate alongside the Su-57. The Okhotnik-B, which has been under development for several years, represents a more ambitious project than the Grom, with a focus on low observability and endurance. However, the development of the Okhotnik-B has been slow, likely due to the complex nature of its design and the impact of the war in Ukraine.
In contrast, the Grom’s more conventional design may allow it to be fielded more quickly and at a lower cost. The decision to prioritize speed and performance over stealth could also be driven by limitations in Russia’s low-observable design and manufacturing capabilities. By adopting a more straightforward design, Kronshtadt may be seeking to deliver a capable UCAV that can be integrated into the Russian military’s existing infrastructure without the need for extensive modifications.
The Grom’s role as a ‘loyal wingman’ also differentiates it from the Okhotnik-B, which is intended to operate more independently. The Grom’s ability to work closely with manned aircraft could make it a valuable asset in joint operations, where coordination between different platforms is essential. This could be particularly important in scenarios involving complex air defense networks, where the Grom could help to overwhelm enemy defenses through sheer speed and numbers.
Implications for Russian Military Strategy
The unveiling of the Grom at Army 2024 is indicative of broader trends in Russian military strategy, particularly in the field of unmanned systems. The focus on high-speed performance and maneuverability reflects a shift away from traditional UCAV roles, which have emphasized endurance and stealth. This change in approach may be driven by the evolving nature of modern warfare, where the ability to quickly adapt to emerging threats is increasingly important.
The Grom’s design also suggests a growing recognition of the need for flexibility in UCAV operations. By developing a drone that can operate both as a ‘loyal wingman’ and potentially engage in air-to-air combat, Russia is positioning itself to address a wider range of operational scenarios. This adaptability could prove crucial in future conflicts, where the ability to rapidly deploy and reconfigure assets will be a key determinant of success.
However, the success of the Grom program is not guaranteed. The lack of confirmed orders and the ongoing challenges facing Russia’s defense industry, including financial constraints and the impact of international sanctions, could hinder the development and deployment of the Grom. Additionally, the drone’s performance claims, particularly its speed and maneuverability, have yet to be fully validated. If these claims do not hold up under real-world conditions, the Grom could struggle to fulfill its intended role.
In conclusion, the introduction of the new Grom drone represents a significant milestone in Russia’s ongoing efforts to develop advanced UCAVs. The shift in design philosophy, from a stealthy, endurance-focused platform to a high-speed, maneuverable drone, reflects broader changes in Russian military strategy. As Russia continues to adapt to the evolving demands of modern warfare, the Grom could play a crucial role in shaping the future of unmanned combat operations.
While challenges remain, particularly in terms of funding and technical validation, the Grom’s potential as a ‘loyal wingman’ and its ability to operate in high-threat environments make it a promising addition to Russia’s military capabilities. As the Grom moves from concept to reality, it will be essential to monitor its development closely, as it may offer valuable insights into the future direction of Russian drone warfare.
