S-70 Okhotnik vs Saegheh

Russia’s Sukhoi S-70 Okhotnik is a 25-ton heavy UCAV designed to operate synchronously with the Su-57 manned fighter, utilizing domestic aerospace structures and stealth geometry. Iran's Shahed Saegheh is a 500 kg airframe scaled down from a captured U.S. RQ-170 Sentinel, prioritizing asymmetrical regional strike capabilities using available propulsion and off-the-shelf components.

Development and Design

Sukhoi’s S-70 program began in 2011, evolving from the stalled Mikoyan Skat project. The airframe uses composite materials and a flying-wing geometry to reduce radar cross-section. While early prototypes utilized exposed circular exhausts, the second prototype integrated a flat nozzle to reduce infrared signatures. In contrast, Shahed Aviation Industries based the Saegheh on the Lockheed Martin RQ-170 Sentinel captured in 2011. Iran scaled the design down by 60% to bypass domestic manufacturing limitations, substituting the Sentinel's radar-absorbent materials for standard fiberglass and composites. The Saegheh-2 (Shahed 191) uses a small turbojet with a frontal air intake, launching from vehicle-mounted racks and recovering on retractable skids, eliminating the need for conventional runway infrastructure.

Specifications and Performances

The size and propulsion disparities dictate their operational roles. The S-70 is a heavy strike asset, powered by an AL-41F derivative turbofan pushing it to 1,000 km/h. Its 25,000 kg maximum takeoff weight allows it to carry 2,000 kg of internal munitions, including the UMPB D-30SN glide bomb, over a 6,000 km range. The Saegheh operates on a different scale entirely. With a maximum takeoff weight of just 500 kg and a top speed of 350 km/h, it is restricted to localized tactical missions. Its payload is limited to roughly 50 kg, enough for two Sadid-1 precision-guided munitions in the internal bays of the Saegheh-2 variant. The S-70 operates at medium-to-high altitudes (18,000 m) for deep strike and ISR, while the Saegheh is confined to a 7,620 m ceiling with a 1,500 km range.

Deployment and usage

Iran integrated the Saegheh into the IRGC Aerospace Force, building approximately 50 units. Its combat record includes:

• A 2018 deployment in Syria, executing strikes with Sadid-1 munitions.
• A February 2018 cross-border infiltration into Israel, ending in its destruction by an Israeli AH-64 Apache.
• Evaluation by Russian defense officials in 2022 for potential procurement or technology transfer.

The S-70 remains in the prototype phase, with two units built by early 2024. Its operational debut exposed severe command-and-control flaws. In October 2024, Russian controllers lost contact with an S-70 over Ukraine, forcing a trailing Su-57 to shoot it down to prevent capture. The wreckage confirmed its payload but exposed vulnerabilities in Russia's secure datalink architecture.

Conclusion

The Saegheh holds the edge in current operational utility and mass deployment, while the S-70 remains an unproven demonstrator. Iran successfully reverse-engineered a foreign asset into a functional, low-cost strike platform that is actively employed in regional conflicts. The S-70 offers superior kinetic capacity, range, and structural stealth, but Russia’s inability to maintain reliable datalinks—resulting in fratricide over Kostiantynivka—negates its hardware advantages. Until Moscow resolves its avionics and command-and-control deficiencies, the Okhotnik cannot function as a reliable loyal wingman, making the combat-tested Saegheh the more effective weapon system today.
