Environmental Sensing Device (military)/Related Articles

Environmental Sensing Device (military): Weapon safety devices that prevent detonation until they detect external conditions consistent with the known mode of delivery, such as changing barometric pressure and radar altitude of a dropped bomb, or the launch acceleration, conditions in space, and reentry of a ballistic missile trajectory; a key safeguard for nuclear weapons ^[e]

• Ballistic missile [r]: A guided missile which, once its engines stop firing, follows a generally parabolic path to its target, defined by momentum, aerodynamic resistance, and gravity ^[e]
• Gravity bomb [r]: A bomb with no supplemental propulsion, whose trajectory is determined by initial velocity and gravity, or by the action of aerodynamic control surfaces. ^[e]
