Editing Shaped charge (section)

===Nuclear shaped charges===
The proposed [[Project Orion (nuclear propulsion)|Project Orion nuclear propulsion]] system would have required the development of [[nuclear shaped charge]]s for reaction acceleration of spacecraft. Shaped-charge effects driven by nuclear explosions have been discussed speculatively, but are not known to have been produced in fact.<ref>Andre Gsponer (2008) "[https://arxiv.org/abs/physics/0510071v5 Fourth Generation Nuclear Weapons: Military Effectiveness and Collateral Effects]"</ref><ref>Dyson, George, ''Project Orion: The Atomic Spaceship 1957–1965'', p. 113. {{ISBN|0-14-027732-3}}.</ref><ref>Dyson, ''Project Orion'', p. 220.</ref> For example, the early nuclear weapons designer [[Ted Taylor (physicist)|Ted Taylor]] was quoted as saying, in the context of shaped charges, ''"A one-kiloton fission device, shaped properly, could make a hole {{convert|10|ft|m|spell=in}} in diameter a thousand feet (305 m) into solid rock."''<ref>McPhee, John, ''The Curve of Binding Energy'', p.159 {{ISBN|0-374-51598-0}}</ref> Also, a nuclear driven [[explosively formed penetrator]] was apparently proposed for terminal ballistic missile defense in the 1960s.<ref>Explosively Produced Flechettes; JASON report 66-121, Institute for Defense Analysis, 1966</ref><ref>Interview with Dr. Richard Blankenbecler http://www.aip.org/history/ohilist/5196.html {{Webarchive|url=https://web.archive.org/web/20110912100014/http://www.aip.org/history/ohilist/5196.html|date=2011-09-12}}</ref>
