A linear shaped charge (LSC) has a lining with V-shaped profile and varying length. The lining is surrounded with explosive, the explosive then encased within a suitable material that serves to protect the explosive and to confine (tamp) it on detonation. "At detonation, the focusing of the explosive high pressure wave as it becomes incident to the side wall causes the metal liner of the LSC to collapse–creating the cutting force."<ref>Accurate Energetic Systems LLC [http://www.aesys.biz/wp-content/uploads/14-102_liner-shaped-charge.pdf] {{Webarchive|url=https://web.archive.org/web/20170122193122/http://www.aesys.biz/wp-content/uploads/14-102_liner-shaped-charge.pdf|date=2017-01-22}}" Linear Shape Charge</ref> The detonation projects into the lining, to form a continuous, knife-like (planar) jet. The jet cuts any material in its path, to a depth depending on the size and materials used in the charge. Generally, the jet penetrates around 1 to 1.2 times<ref>{{cite web |title=Linear Shaped Charge |url=http://www.aesys.biz/wp-content/uploads/14-102_liner-shaped-charge.pdf |website=aesys.biz |publisher=Accurate Energetic Systems, LLC |access-date=2016-02-10 |archive-date=2017-01-22 |archive-url=https://web.archive.org/web/20170122193122/http://www.aesys.biz/wp-content/uploads/14-102_liner-shaped-charge.pdf |url-status=dead}}</ref> the charge width. For the cutting of complex geometries, there are also flexible versions of the linear shaped charge, these with a lead or high-density foam sheathing and a ductile/flexible lining material, which also is often lead. LSCs are commonly used in the cutting of rolled steel joists (RSJ) and other structural targets, such as in the [[building implosion|controlled demolition]] of buildings. LSCs are also used to separate the stages of [[multistage rocket]]s, and [[Flight termination|destroy them]] when they go errant.<ref>{{Cite web |last=Manley |first=Scott |date=2023-04-30 |title=How To Destroy Wayward Rockets - Flight Termination Systems Explained |url=https://www.youtube.com/watch?v=yekMWWcpfOA |website=YouTube}}</ref>
