This drawing number represents the most recent design of three versions of the Box Type M Magazine that has been constructed. The initial design was approved by DDESB-KO memo of 9 Apr 93 for construction at NAVWPNSTA Seal Beach. The two subsequent design variations were approved by DDESB-KO memo of 1 Dec 99, for construction at NAVYPNSTA Yorktown. All new construction of Box Type M ECM will be in accordance with drawings 10400001 through 10400027.

MSM Standard 421-80-07 replaces the previous MSM Standard 421-80-06 (modified). The new series updates the drawings to meet current AEC CAD standards, improved plan readability, constructability, and correct omissions within the construction drawings. Another key element performed during the revision was the incorporation of lessons learned from previous MSM projects at various user organizations. In addition to the drawings, a conventional structural load analysis was performed to identify some key loading limits, which will assist the designer during the site-adaption process.

Headwall components have been re-analyzed under the 7-bar blast loading from DoD 6055.09-M using the methodology of UFC 3-340-02. The remaining components are as originally designed. In addition to the drawings, a conventional structural load analysis was performed to identify some key loading limits, which will assist the designer during the site-adaption process and a new retaining wall design was completed to simplify construction of the wing walls. The documentation will not include specifications.

Comments/Design Consideration

The HPM design concept was granted DDESB approval as a 7-Bar magazine during the 319th Meeting of 27 January 2000. A preliminary design document, dated 3 July 2001, was completed by NAVFAC. The HPM consist of four separate ordnance storage bays that are treated as independent magazines (i.e., independent MCE). Each storage bay can store up to 30,000 lbs. of net explosive weight. Each bay can optionally be subdivided into two separate storage areas with the use of the "Re-locatable" Modular Wall. Each subdivided storage area can also store up to 30,000 lbs. of net explosive weight, thereby increasing the total storage capacity of the HPM. The separation of the storage bays or subdivided storage areas also allows for the storage of incompatible ordnance in adjacent bays. The maximum storage capacity of a HPM with no subdivided bays is 120,000 lbs. net explosive weight (NEW). If all four bays are subdivided, the maximum storage capacity is 240,000 lbs. NEW.

No HPM, other than a test magazine, has been constructed. Construction drawings must be finalized and approved by the DDESB prior to construction start. The HPM design consists of multiple cells, which use non-propagation wall technology to prevent propagation of an incident to adjacent cells. Therefore, the MCE and QD associated with the HPM are based on 60,000 pounds NEW vice the total quantity of explosives stored in all cells of the HPM. Specific mixing and compatibility criteria will apply to storage of ammunition within each cell. As part of the approval, all HD 1.1 and 1.2 AE was placed within five possible HPM Sensitivity Groups. The Joint Hazard Classification System (JHCS) identifies these groups, which define what can be stored together in an HPM. The HPM is not an earth-covered magazine. The HPM is earth-bermed (except for the truck entrance) and moveable RC lids form the roof of each storage cell. The area above the storage cells is enclosed by a lightweight metal panel building, within which is contained the crane that is used for AE movement in the HPM.
