Strong links, at least in US nuclear weapons, are always implemented as electro-mechanical systems such as motor-driven switches. [2] There are two main requirements: when functional, never to allow an invalid signals to penetrate the energy barrier, and never to fail in a way that can pass a signal though the barrier before the weak links inside the exclusion zone have also failed.
In the United States military's strategic nuclear weapon nuclear command and control (NC2) system, an Emergency Action Message (EAM) is a preformatted message that directs nuclear-capable forces [1] to execute specific Major Attack Options (MAOs) or Limited Attack Options (LAOs) in a nuclear war.
An example of a low-explosive train is a rifle cartridge, which consists of a primer consisting of a small amount of primary high explosive which initiates the explosive train; an igniter which is initiated by the primer and creates a flame that ignites the propellant
Friendly surface/submarine-launched AShM (for example, Harpoon, Exocet, Otomat). Bullseye An established point from which the position of an object can be referenced; made by cardinal/range or digital format. Bump/Bump-up Start temporary increase of flight altitude to set the aircraft to a favorable glide path to the target on the attack run ...
Insensitive munitions are munitions that are designed to withstand stimuli representative of severe but credible accidents. The current range of stimuli are shock (from bullets, fragments and shaped charge jets), heat (from fires or adjacent thermal events) and adjacent detonating munitions.
For example, a large bomb casing was filled with small sticks of incendiary ; the casing was designed to open at altitude, scattering the bomblets in order to cover a wide area. An explosive charge would then ignite the incendiary material, often starting a raging fire.

There are also events of no safety relevance, characterized as "out of scale". [37] Examples: 5 March 1999: San Onofre, United States: Discovery of suspicious item, originally thought to be a bomb, in nuclear power plant. [38] 29 September 1999: H.B. Robinson, United States: A tornado sighting within the protected area of the nuclear power plant.
