MIL-STD-1399 -072A PT 2

Abstract

Policies and procedures established by MIL-STD-1399 are mandatory. (This section defines the standard interface requirements for the design of systems, equipment, and structure which may be subjected to the blast generated by own ship guns.) This section and the basic standard are to be viewed as an integral single document. <br>This section addresses the interface characteristics of gun blast effects for ship guns ranging from 78 millimeter (mm), 3 inch/50 to 16 inch/50, and the characteristics of Hi-Frag ammunition versus standard ammunition. Small caliber guns, such as Close-in-Weapon System (CIWS) are excluded since they produce insignificant blast effects, and may generally be ignored for ship and equipment design purposes. <br>The basic characteristics and constraint categories of this interface are shown symbolically in <a>figure 1</a>. The specific interface characteristics and constraints pertinent to this section are described in section <a>5</a>. <br>The criteria of this section are applicable to new ship acquisitions, modernizations, or conversions, and to system and equipment intended for installation on board such ships. Systems and equipment intended for installation on board active fleet ships shall possess blast resistance characteristics not less than those originally required for the ship in question. The criteria of this section apply only to ships designed for the installation of guns. <b><u>Intended Use:</u></b> This standard is to be used in technical development plans and in design and acquisition specifications for ship acquisitions, modernizations, or conversions, and shipboard systems and equipment. <br>
