Of course, Darren, I was thinking more of Quad 50's maybe......Laser-aimed Vulcan cannon, perhaps.
The Vulcan, on which the CIWS is based, fires 100 20mm rounds per second, IIRC. That would make it more expensive and reduce the likelihood of survivors to interrogate. Besides, there is a definite coolness factor.
"Laser"
