Editing Exploding-bridgewire detonator (section)

=== Use in nuclear weapons ===

Since explosives detonate at typically 7–8 kilometers per second, or 7–8 meters per millisecond, a 1 millisecond delay in detonation from one side of a nuclear weapon to the other would be longer than the time the detonation would take to cross the weapon. The time precision and consistency of EBWs (0.1 microsecond or less) are roughly enough time for the detonation to move 1 millimeter at most, and for the most precise commercial EBWs this is 0.025 microsecond and about 0.2&nbsp;mm variation in the detonation wave. This is sufficiently precise for very tight tolerance applications such as nuclear weapon [[explosive lens]]es.<!-- cite to Nuclear Weapons FAQ -->

In the US, due to their use in nuclear weapons, these devices are subject to nuclear control authorities, according to the Guidelines for the Export of Nuclear Material, Equipment and Technology. EBWs are on the [[United States Munitions List]], and exports are highly regulated.<ref name="RISI-Export">{{cite web |url=http://www.teledynerisi.com/1techtopics/pdf/1193.pdf |title=RISI Technical Topics 11-92 ATF Licenses
