Head-to-Head Analysis
Stealth and Survivability
The F-47 NGAD's sixth-generation stealth features make it nearly invisible to radar, with advanced materials and design that surpass the F-22 and F-35, allowing it to penetrate heavily defended airspace undetected. In contrast, the Su-35S lacks true stealth capabilities, relying on speed and maneuverability to evade threats, which makes it vulnerable in modern electronic warfare environments. This generational gap means the F-47 can operate closer to targets without detection, integrating with drone swarms for enhanced situational awareness. However, the Su-35S's proven combat record in Syria demonstrates its ability to survive in less advanced threat scenarios through sheer agility and electronic countermeasures.
F-47 NGAD is better due to superior stealth, providing a critical edge in high-threat environments where radar avoidance is paramount.
Speed and Range
The F-47 NGAD achieves supercruise above Mach 1.5 without afterburners, thanks to its adaptive cycle engine, and boasts a 1852 km range, enabling long-duration missions with minimal fuel concerns. The Su-35S, with a top speed of Mach 2.25 and a 3600 km range, excels in sustained high-speed flights and extended patrols, making it ideal for vast operational theaters like the Middle East. While the F-47's range is half that of the Su-35S, its efficiency in loitering and coordinating with drones offsets this. The Su-35S's advantage in raw distance could be crucial for intercept missions over large areas.
Su-35S is better for scenarios requiring extensive range, as its superior distance capabilities outweigh the F-47's efficient speed.
Avionics and Guidance
The F-47 NGAD's AI-enabled cockpit and advanced networking allow for real-time data fusion and drone integration, turning it into a flying command center with superior situational awareness. The Su-35S features a robust Irbis-E radar with 400 km detection, but its avionics are less integrated and more susceptible to cyber threats compared to Western systems. This difference highlights the F-47's edge in information warfare, where rapid decision-making is key, versus the Su-35S's strength in traditional radar-based engagements. Overall, the F-47's tech represents a leap for future conflicts involving networked forces.
F-47 NGAD is better due to its advanced AI and networking, which provide unmatched guidance in complex, multi-domain operations.
Weapons and Payload
The F-47 NGAD uses internal weapons bays to maintain stealth, supporting precision strikes with CCA drone wingmen for extended reach and versatility. The Su-35S, with 12 hardpoints and up to 8 tons of ordnance, offers massive external payload options for diverse missions, including ground attack, but at the cost of increased detectability. This contrast shows the F-47's focus on quality over quantity, ideal for stealthy operations, while the Su-35S prioritizes firepower for immediate, high-intensity engagements. In coalition scenarios, the F-47's integration could amplify effectiveness.
Su-35S is better for raw payload capacity, making it more suitable for missions requiring heavy armament loads.
Cost and Maintenance
At an estimated $200M+ per unit, the F-47 NGAD's high cost limits production and requires sophisticated maintenance, potentially straining budgets in prolonged conflicts. The Su-35S, priced at around $85M, is more affordable and has been fielded in various environments, though its Russian avionics can be less reliable and costlier to upkeep over time. This makes the Su-35S attractive for nations like Iran seeking capable aircraft without premium expenses, while the F-47's advanced features justify its price for high-end users. The trade-off affects procurement decisions in resource-constrained settings.
Su-35S is better for cost-sensitive operations, as its lower price and established maintenance network provide better value for widespread deployment.
Scenario Analysis
Air superiority over the Persian Gulf
In a scenario involving air superiority missions over the Persian Gulf, the F-47 NGAD's stealth and AI integration would allow it to detect and engage Su-35S aircraft from beyond visual range while evading radar detection, coordinating with drone swarms for overwhelming force. The Su-35S, with its superior maneuverability and longer range, could excel in dogfights and prolonged patrols, using its powerful radar to challenge incoming threats. However, the F-47's generational advantages in electronic warfare would likely neutralize the Su-35S's strengths, leading to quicker mission dominance.

Intercepting drone swarms in the Middle East
For intercepting drone swarms, the F-47 NGAD's role as a command node for CCA drones would enable seamless coordination and autonomous targeting, providing a decisive edge in swarm warfare. The Su-35S, while capable of engaging drones with its weapons load, lacks the integrated ecosystem for efficient swarm management, relying on pilot skill and radar for individual intercepts. In this context, the F-47 could neutralize threats more efficiently, whereas the Su-35S might struggle with the volume and speed of modern drone attacks.

Escorting strike packages against fortified targets
In escorting strike packages, the Su-35S's speed, range, and maneuverability would protect formations over long distances, using its thrust-vectoring for evasive maneuvers against missiles. The F-47 NGAD, with its stealth, could lead escorts undetected, using AI to anticipate threats and direct drones for added protection. However, the Su-35S's ability to carry more ordnance might make it a dual-role asset, though its lack of stealth could expose it to early detection in high-threat areas.

Complementary Use
In certain hybrid warfare scenarios, the F-47 NGAD and Su-35S could theoretically complement each other by leveraging the F-47's stealth for initial reconnaissance and the Su-35S's firepower for follow-up strikes, though this is unlikely in adversarial contexts like the Coalition vs. Iran Axis. For instance, a defense planner might use the Su-35S for area denial while the F-47 coordinates drone assets to exploit gaps, creating a layered defense. This combination could enhance operational flexibility, but integration challenges due to differing technologies and alliances would limit practicality.
Overall Verdict
The F-47 NGAD emerges as the superior choice for future-oriented defense strategies, particularly in high-tech conflicts where stealth, AI, and drone integration provide a clear edge over the Su-35S's traditional strengths. While the Su-35S offers immediate advantages in range, cost, and maneuverability, making it viable for budget-constrained operators like Iran, the generational leap of the F-47 positions it as a game-changer in air dominance. Defense planners should prioritize the F-47 for scenarios involving advanced threats, as its capabilities could decisively outmatch fourth-generation fighters in electronic warfare and long-range engagements. Ultimately, this comparison reveals the F-47's potential to redefine aerial combat, recommending its adoption for coalitions facing evolving Iran Axis challenges.
