GPT; 2025最好在服役的戰鬥機

As of 2025, the best fighter jet in service depends on the criteria used for evaluation—stealth, speed, agility, firepower, or advanced avionics. Here are the top contenders:

1. Lockheed Martin F-35 Lightning II (USA)

• Type: Stealth multirole fighter

• Strengths: Best avionics, networked warfare capabilities, sensor fusion, and versatility (F-35A/B/C variants).

• Weaknesses: Not the fastest or most agile, expensive maintenance.

2. Lockheed Martin F-22 Raptor (USA)

• Type: Air superiority stealth fighter

• Strengths: Unmatched maneuverability, supercruise (Mach 1.8), stealth, and air-to-air combat supremacy.

• Weaknesses: Limited production, no export, high maintenance costs.

3. Chengdu J-20 Mighty Dragon (China)

• Type: Stealth air superiority fighter

• Strengths: Long range, stealth design, AESA radar, powerful WS-15 engines (newer versions).

• Weaknesses: Less maneuverable than F-22, uncertain avionics and sensor fusion capabilities.

4. Sukhoi Su-57 Felon (Russia)

• Type: Stealth multirole fighter

• Strengths: Supermaneuverability, advanced IRST, high-speed performance.

• Weaknesses: Limited stealth compared to F-22/F-35, small production numbers.

5. Eurofighter Typhoon (Europe)

• Type: 4.5-generation multirole fighter

• Strengths: Exceptional dogfighting capabilities, powerful radar, and modular design.

• Weaknesses: Lacks stealth, but upgrades (Radar 2, enhanced weapons) improve survivability.

6. Dassault Rafale (France)

• Type: 4.5-generation multirole fighter

• Strengths: Excellent agility, carrier-capable (Rafale M), advanced sensors and Spectra EW suite.

• Weaknesses: Lacks stealth, but excels in versatility.

Overall Best in 2025

• For stealth and networked warfare: F-35 Lightning II

• For air superiority and dogfighting: F-22 Raptor (if available)

• For non-US alternatives: J-20 (China) Su-57 (Russia)

• For proven multirole performance: Rafale Typhoon
