Fighter squadrons are military units that operate fighter aircraft, which are designed for air-to-air combat. These squadrons are typically part of an air force and are responsible for defending airspace, engaging enemy aircraft, and providing support for ground forces. Each squadron usually consists of several aircraft, pilots, and support personnel. Fighter squadrons can vary in size and structure, often organized into groups or wings. They may be equipped with advanced technology and weapons systems to enhance their combat capabilities. Notable examples include the U.S. Air Force and Royal Air Force, which have a long history of operating fighter squadrons in various conflicts.
