F-35 History & Development
The F-35 stealth fighter originated from the Joint Strike Fighter program launched in the 1990s. The goal was to develop a single aircraft that could serve multiple branches of the military, replacing older platforms such as the F-16 Fighting Falcon and AV-8B Harrier.
The first prototype of the F-35 flew in 2006, marking a major milestone in stealth aviation. After years of testing, development, and international collaboration, the aircraft entered operational service around 2015. Today, it stands as a symbol of modern aerial warfare and technological dominance.
This program involved several allied nations, making it the largest multinational defense project in history. Countries contributed funding, testing, and operational input, shaping the aircraft into a globally used platform.
