scope:

This section is an integral part of MIL-STD-1399. When the interface between the weather environment and ship/systems/equipment is under consideration this section and the standard must be viewed as a single document. The procedures established by MIL-STD-1399 are mandatory.

This section establishes interface requirements for shipboard systems/equipment which are exposed to or affected by the weather to ensure compatibility between such systems/equipment and the weather environment.

The interface which is the concern of this section and the basic characteristic and constraint categories involved at this interface are shown symbolically on figure 1 (see "Definitions" of MIL-STD-1399):

The particular interface characteristics and constraints pertinent to this section are described in 5.2 and 5.3.

This section applies to the weather environment (see 3.1) as it relates to the design of ships/systems/equipment. It does not apply to the concomitant effects of ship motion and attitude or to wave impact and boarding seas.
