American F-35 Lightning II Stealth Jet Fighter: History, Variants, Specifications, Price, and Global Operators
Introduction
The F-35 Lightning II is the world’s most advanced fifth-generation stealth multirole fighter aircraft, designed to dominate both air-to-air and air-to-ground combat. Built by Lockheed Martin, it represents a milestone in aerospace technology — combining stealth, speed, agility, and electronic warfare capability. Since its induction, the F-35 has redefined aerial combat, symbolizing American innovation and allied airpower across the globe.
1. History and Development of the F-35 Lightning II
The F-35 Lightning II evolved from the Joint Strike Fighter (JSF) program launched in the 1990s to create a single-platform stealth fighter for the U.S. Air Force, Navy, and Marine Corps.
✔️ After extensive competition, Lockheed Martin’s X-35 prototype won over Boeing’s X-32 in 2001.
✔️ The aircraft’s first flight took place on December 15, 2006, and the first operational unit was declared combat-ready in 2015.
✔️ The goal was to develop a versatile multirole stealth aircraft capable of replacing older fleets like the F-16, A-10, AV-8B Harrier, and F/A-18 Hornet.
✔️ Today, the F-35 is operated by more than 17 countries, cementing its reputation as the world’s most advanced fighter jet family.
2. F-35 Lightning II Variants and Their Roles
The F-35 program includes three main variants, each optimized for unique operational needs while sharing more than 80 percent common systems.
F-35A (Conventional Takeoff and Landing)
F-35B (Short Takeoff / Vertical Landing)
F-35C (Carrier Variant)
