Which aircraft is primarily used for long-range bombing missions in the U.S. military?

The B-52 Stratofortress is the primary aircraft used for long-range bombing missions in the U.S. military due to its design and operational capabilities. This aircraft has been a key component of the U.S. Strategic Air Command since its introduction in the 1950s, and its capability to carry a large payload over extremely long distances makes it uniquely suited for this role.

The B-52 can deliver a variety of munitions, including nuclear and conventional bombs, and its range is further enhanced with in-flight refueling capabilities, allowing it to strike targets deep behind enemy lines without needing to land or refuel frequently. Additionally, its ability to operate in various environments, alongside its large bomb capacity and versatility in combat operations, solidifies its status as a primary long-range bomber.

In contrast, the other aircraft listed have different primary functions: the B-1 Lancer is also a long-range bomber but is primarily designed for supersonic speeds and low-level penetration missions. The F-15 Eagle is an air superiority fighter focused on gaining and maintaining control of the air, while the F/A-18 Hornet serves multi-role functions including fighter and attack missions but is not optimized for long-range bombing like the B-52.
