Strategic bombers are large military aircraft designed to carry out long-range bombing missions. They can deliver conventional or nuclear weapons and are essential for a country's defense strategy. These bombers are capable of flying at high altitudes and can cover vast distances, making them effective for striking targets deep within enemy territory. Examples of strategic bombers include the B-52 Stratofortress and the B-2 Spirit used by the United States Air Force. These aircraft are equipped with advanced technology for navigation and targeting, allowing them to operate in various combat environments while minimizing the risk to their crews.
