Fleet Ballistic Missiles
Fleet Ballistic Missiles (FBMs) are a type of missile designed to be launched from submarines. They are primarily used as a strategic deterrent, providing a second-strike capability in the event of a nuclear conflict. FBMs are equipped with nuclear warheads and can travel long distances, making them a key component of a nation's nuclear triad.
These missiles are typically housed in vertical launch systems within submarines, such as the Ohio-class submarines of the United States Navy. FBMs are launched while the submarine is submerged, allowing for stealthy deployment and enhancing the survivability of the missile system against potential threats.
