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. Examples of strategic bombers include the B-52 Stratofortress and the B-2 Spirit, which are capable of flying great distances without needing to refuel frequently. These bombers are equipped with advanced technology, including stealth capabilities, allowing them to evade radar detection. Their primary role is to deter potential threats and provide a powerful response option in times of conflict, making them a critical component of modern air forces.
