Comments/Design Considerations -
This design superceded the initial M-Type magazine design constructed at NWS Seal Beach. CA (see 8027514 through 8027532). The DDESB approved the modified Type M magazine as a "default", 7-bar structure for storage of up to 350,00(1 pounds of HD 1.1 explosives and approved the siting of 14 Type M (modified) magazines at WPNSTA. Yorktown. The proposed modification increased the ceiling height by four (4) feet and upgraded the magazine's foundation to carry the additional weight of the increased height Two of the 14 ECMs constructed have foundations with slightly less carrying capacity. This is because their construction was started as the Type M design was evolving.
