Which generation fighter is described as having superior engine performance with turbofan and AI radars including mechanically scanned, PESA, and AESA?

• A. Fourth generation
• B. Second generation
• C. Third generation
• D. First generation

Answer: (A)

Propulsion and sensors define this level of fighter design. Fourth-generation fighters are built around significantly improved turbofan engines that deliver higher thrust with better efficiency, enabling greater speed, range, and payload capability. At the same time, their radar suites showcase a clear progression from mechanically scanned systems to more advanced phased-array technologies, moving through PESA to AESA. Mechanically scanned radars rely on physically rotating antennas, while PESA uses a single phased array with electronic beam steering, and AESA employs multiple transmit/receive modules to form many beams simultaneously with high reliability and detectability. This combination of robust, high-performance engines and the evolution to AESA-type radar is the hallmark of fourth-generation fighters, setting them apart from earlier generations that did not feature this level of engine performance or radar capability.
