Cables covered by this specification are used or interconnecting fire control instruments, generator units, weapons in anti-aircraft artillery and guided missile systems. Cables are intended for use where oil, ozone, and weather resistance are of major importance and flexibility over an ambient temperature range of -65 ºF and 160 ºF is necessary. Cables are stretched on the ground or laid in a shallow trench where the terrain may vary from swamp to dry, rocky ground. There is frequent realign and unreeling which may cause kinking, twisting and dragging when in contact with the ground.
