F-14 Tomcat vs Su-35 Flanker-E

Designed forty years apart, the Grumman F-14 Tomcat and Sukhoi Su-35 Flanker-E approach air superiority through inverted doctrines. The F-14 was engineered as a carrier-based interceptor, reliant on the AWG-9 radar and AIM-54 Phoenix to destroy Soviet bombers beyond visual range. Conversely, the Su-35 evolved from the Su-27 as a land-based air superiority fighter weighted toward kinematic performance and high-angle-of-attack maneuverability over raw standoff intercept metrics.

Development and Design

Grumman’s F-14 utilized variable-geometry wings to bridge conflicting US Navy requirements: long on-station loiters at low speeds and Mach 2 intercepts. Early iterations suffered from Pratt & Whitney TF30 engines, which experienced compressor stalls at high angles of attack—a fatal flaw in dogfighting until General Electric F110 engines arrived in the F-14B. Sukhoi’s Su-35S, emerging decades later, replaced the Su-27’s mechanical controls with a digital fly-by-wire system and integrated 3D thrust-vectoring AL-41F1S turbofans. While the Tomcat required a radar intercept officer to manage the AWG-9, the Su-35 reduced pilot workload via cockpit automation. Sukhoi opted for the Irbis-E passive electronically scanned array (PESA) radar, placing it at a technological disadvantage against modern fighters equipped with active (AESA) systems.

Specifications and Performances

Both airframes operate in the heavy fighter class, sharing maximum takeoff weights near 34,000 kg.

• Thrust: The Su-35 generates 27,400 kgf compared to the F-14’s 22,408 kgf.
• Agility: The Russian airframe achieves a thrust-to-weight ratio exceeding 1.1:1 at combat weight, enabling post-stall aerodynamics that the F-14 airframe could not mechanically survive.
• Speed & Range: Top speeds are functionally identical (2,485 km/h for the F-14; 2,500 km/h for the Su-35). Range metrics favor the Su-35 (3,600 km vs. 3,000 km), reflecting the fuel-carrying efficiency of the Flanker’s blended wing-body design over the drag-heavy swing-wing mechanics of the Tomcat.

Deployment and usage

The F-14 achieved its highest kill ratios with the Iranian Air Force during the 1980–1988 Iran-Iraq War. Iranian Tomcats scored over 130 kills against Iraqi aircraft, validating the AIM-54 in combat. In US service, the Tomcat scored specific kills against Libyan fighters before transitioning to a strike role over Iraq. The Su-35S deployed to Syria in 2016 for fighter sweeps, facing no aerial opposition. Over Ukraine, the VKS utilizes the Su-35S with R-37M missiles for standoff engagements. Russian forces have lost multiple Su-35s to ground-based air defenses, exposing gaps in its electronic warfare integration. Export orders from Egypt and Indonesia were canceled due to CAATSA sanctions.

Conclusion

In a kinetic comparison, the Su-35 holds the edge in modern air-to-air combat. Its thrust-vectoring engines and digital flight controls provide a distinct within-visual-range advantage over the F-14’s mechanical limitations. While the Tomcat executed its 1970s fleet defense mandate by intercepting targets at 160 km with the AIM-54, the Su-35’s integration of the R-37M matches this standoff distance while retaining close-in agility. The Su-35 outmatches the F-14 in raw flight performance and armament flexibility, though its reliance on PESA radar architecture caps its effectiveness against AESA-equipped modern adversaries.
