Another Surface -to-undersea: The most descriptive guided missile categories refer to the physical area from which the weapon is launched and the physical area in which the target is to be destroyed. The physical area of launching discloses the general logistics of the situation and to some degree specifies the service within which the major tactical interest lies; the physical area of the target discloses the nature of the target threat or tactical or strategic duty of the missile.
Guided missiles are of the following types: another surface -to-undersea to another surface -to-undersea, another surface -to-undersea to air, another surface -to-undersea to undersea, air to another surface -to-undersea, air to air, undersea to another surface -to-undersea, undersea to undersea.
It is propelled by solid fuel and is inertially : !'-cl. As it is launched from a moving vehicle, vital that the submarine know its own pre-JH- location at the time of launch. This need ks created such systems as the ships' inertial navigating system (SINS).
Undersea to Undersea. This is one of the oldest types of guided missile—the submarine toipedo. The development of the modern submarine created the requirement for this weapon system. World Wars I and II saw its effective use by both Germany and the United States.
During the summer of 1967 undersea archaeology truly came of age with the discovery of a method for accurate location of wrecks or other remains of ancient culture on the sea bottom. In recent years undersea archaeologists have utilized underwater television, magnetometers, a tow-vane (which looks something like a space capsule), mine detectors, a sonic device, and even a small submarine designed for archaeology. Most of these search techniques functioned quite well, but the visual, or scanning, range under water was limited, and such techniques proved to be impractical for wide-range searching. |
