The A244 was initially conceived at Whitehead Alenia in 1968 as a replacement for the USN Mark 44 Mod 2 and shares many design similarities with the older weapon. A244 entered service in 1971 although development continued through 1973, and mass production began in 1975. The weapon was superseded by A244/S which entered service in 1984.
The Long Range Acoustic Device (LRAD) is an acoustic hailing device developed by Genasys (formerly LRAD Corporation) to send messages and warning tones over longer distances or at higher volume than normal loudspeakers, and as a non-lethal directed-acoustic-energy weapon. LRAD systems are used for long-range communications in a variety of ...
The term SCR was part of a nomenclature system developed for the U.S. Signal Corps, used at least as far back as World War I.Three-letter designators beginning with "SC" were used to denote complete systems, while one and two-letter designators (such as "BC", for basic component, "FT" for mounting, etc.) were used for components.
Currently manufactured by ThalesRaytheonSystems, the system is a long-range version of "weapon-locating radar", designed to detect and track incoming artillery and rocket fire to determine the point of origin for counter-battery fire. It is currently in service at brigade and higher levels in the United States Army and by other countries.
