F-15E Strike Eagle vs Su-34 Fullback

McDonnell Douglas developed the F-15E Strike Eagle by adapting an air superiority airframe into a deep interdiction platform, retaining the kinematic performance of a dedicated fighter. Sukhoi engineered the Su-34 Fullback by taking the Su-27 airframe and heavily modifying its forward section to function as a dedicated, armored tactical bomber to replace the Su-24. While both occupy the twin-engine, heavy strike fighter category, their structural divergence dictates completely different operational envelopes.

Development and Design

The F-15E retains the tandem seating and aerodynamic profile of the F-15, relying on conformal fuel tanks (CFTs) to extend unrefueled range without sacrificing weapon hardpoints. This minimizes drag and preserves the airframe’s high-G maneuverability. Sukhoi opted for a side-by-side cockpit to improve crew coordination on long-duration sorties. The Su-34 incorporates a 17mm titanium armored "bathtub" around the cockpit, inflating its empty weight to 20,000 kg—nearly 5,600 kg heavier than the F-15E. This armor reflects Soviet doctrine expecting low-level penetration through dense short-range air defense (SHORAD) networks, a design choice that permanently compromises the Su-34's agility and air-to-air viability.

Specifications and Performances

The F-15E’s twin Pratt & Whitney F100-PW-229 engines generate 26,308 kgf of thrust against a 14,379 kg empty weight, enabling a 2,655 km/h top speed and a high thrust-to-weight ratio. The Su-34, powered by AL-31F turbofans, produces 25,000 kgf of thrust but must push a 45,000 kg maximum takeoff weight, limiting its speed to 2,120 km/h and severely restricting its climb rate.

• Targeting Infrastructure: Modern F-15E variants utilize AESA radars and advanced external targeting pods (Sniper, Litening) for autonomous precision strikes at high altitudes. The Su-34 relies on its internal Platan electro-optical targeting system, which lacks the resolution and field of regard of Western pods, limiting its ability to self-designate targets from safe standoff distances.

Deployment and usage

The F-15E has a 30-year combat record. During Desert Storm, it hunted Scud launchers; over the Balkans and Afghanistan, it delivered precision-guided munitions (PGMs) from medium altitudes, bypassing SHORAD entirely. The Su-34’s record is strictly bifurcated. In Syria, operating against insurgents lacking complex anti-air capabilities, it functioned adequately dropping unguided FAB-500s. However, the 2022 invasion of Ukraine exposed systemic flaws. Russian forces repeatedly committed Su-34s to low-altitude unguided bomb delivery profiles due to PGM shortages. This resulted in dozens of documented airframe losses to man-portable air-defense systems (MANPADS) and medium-range SAMs. The titanium armor proved insufficient against modern kinetic interceptors.

Conclusion

The F-15E outperforms the Su-34 in contested airspace. By operating at medium-to-high altitudes with advanced targeting pods and reliable PGMs, the F-15E avoids the low-altitude threat environment the Su-34 was built to survive. Furthermore, the F-15E retains credible beyond-visual-range air-to-air lethality with AIM-120s, whereas the heavily burdened Su-34 is defensively deficient against modern fighters. The Su-34's side-by-side layout suits permissive patrol environments, but in peer-level combat, its reliance on low-altitude penetration makes it highly vulnerable. The global market reflects this: 525 F-15Es have been built with extensive export success, while the Su-34, despite a lower $36.0 million price tag, sits at 155 units with zero foreign buyers.
