MIL-PRF-11767 Relay Assembly: Gun-Firing, Waterproof, 24 Volt DcThis specification covers one type of waterproof gun-firing relay assembly with a nominal rating of 24 volts \(V\) direct current \(dc\) for use in the main gun and machine gun circuits of military combat vehicles. The assembly consists of relays which control the firing of the main gun by the operation of a time delay circuit and a separate fast-operating, fast-release relay which controls the firing of the machine gun \(see 6.1\).

3.1 First article. When specified (see 6.2), a sample shall be subjected to first article

inspection in accordance with 4.3.

3.2 Design, materials, and manufacturing process. Unless otherwise specified (see 6.2),

the design, materials, and manufacturing process selection is the prerogative of the contractor as

long as all articles submitted to the government fully meet the interface and interoperability,

environmental, support and ownership, and operating requirements specified herein.

3.2.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered,

or environmentally preferable materials should be used to the maximum extent possible provided

that the material meets or exceeds the operational and maintenance requirements, and promotes
