Meet the U.S. Navy’s New $1.5 Billion Stealth Fighter: The X-47B

The development of unmanned aerial vehicles for military use in the United States dates back to the early 20th century, with one of the earliest examples being the Kettering Bug, which was developed during World War I. However, it was during World War II that UAV technology significantly advanced. The US military developed and used drones like the Radioplane OQ-2 and the Interstate TDR for various purposes, including target practice and surveillance.
