Submarine-launched ballistic missiles (SLBMs) are ejected in this manner to the ocean surface from tubes within the submerged vessel. See also cruise missile; rocket; smart bomb; torpedo.

…sea in the form of submarine-launched ballistic missiles. The safeguarding or threatening of nuclear submarines has inspired a set of tactics unique in history. These tactics are among each nation’s most closely guarded secrets and have never been used in anger, so that all knowledge of them is theoretical, based…
