-H-

Harpoon -- -- Antiship cruise missile.

Head -- -- Marine term for bathroom.

Helm -- -- The control yoke (steering wheel) that turns the ship’s rudder. Also short for helmsman.

Horizontal Salvo -- -- Multiple torpedoes shot toward the target with slightly different bearings to increase the chances of a hit.

Hot Racking -- -- When the number of crew members exceeds the number of racks, the lowest ranking enlisted men are forced to “hot rack,” the situation in which one watchstander occupies the rack while the other is on watch, and the rack never gets a chance to cool off.

Hovering System -- -- A depth control computer system that keeps the ship in one point underwater. Used by boomers when launching missiles. Used by fast attack submarines to establish a desired vertical speed (depth rate) to vertical surface through polar ice.

Hull -- -- The pressure-tight shell of a submarine, also known casually as the “people tank.” For single hulled ships, such as American vessels, this shell is steel. For double-hulled Russians, it could be either steel or titanium. Other navies use steel.

Hull Array -- -- One of the sonar hydrophone element assemblies (arrays) of the BQQ-10 sonar suite, consisting of multiple hydrophones placed against the skin of the hull over about one third of the ship’s length. Used mostly as a backup to the spherical array because the hull array’s sensitivity is reduced by own-ship noise generated inside the hull.

HUMINT -- -- Human intelligence, gained by foreign agents or American intelligence officers.

Hydrophones -- -- An underwater microphone or earphone, depending on its use. A hydrophone is a piezoelectric material that deforms when subjected to an electrical current. In active sonar, the electrical current comes from the sonar suite to generate vibrations to cause a sound pulse or ping. In passive sonar, incoming sound waves force the material to vibrate, generating an electrical current that is analyzed by the sonar suite’s computer and displayed in the sonar room and in the control room.
