The LMC Mine. This was an experimental development started in 1933. It was a moo-red mine designated to be laid from "vertical-shaft" aircraft (He 59) which were, how-ever, discontinued. Accordingly, the development of the LMC mine was discontinued, and the information gained was directed to the development of the LMF. It was intended to have the same general shape as the LMB mine, with a total weight of approximatey 2200 pounds, and a charge weight of approximately 660 pounds. Information on the firing de-vice used is conflicting. According to one report, influence units were used; according to another, chemical horns were used.
