Blitmanite 834, a derivative of blitmanite, was a magnesium-based explosive. This explosive was used in remote spectroscopy vaporization devices for scientific and industrial applications. It was not recommended for use underwater. It was provided in several different sizes ranging from 0.02 gram to 2.3 kilograms, depending on the application. In 2367, this explosive was stored on aboard the Federation starship USS Enterprise-D. This compound was named after Leslie Blitman, who in 1978 recruited Mike Okuda into joining the Honolulu Science Fiction Society. [1]
