SONOBUOYS IN A NUTSHELL
Sonobuoys are classified by size (A, B, C, etc.) and type (active, passive or measurement). All U.S.-manufactured sonobuoys, except the MK-84, are A-size (approx. 4 7/8 in. X 36 in.). Some countries have moved to half-size, or A/2, as a preferred configuration.
During the Cold War, passive detection in deep water was the strategy of choice to covertly track nuclear submarines around the world. Since former Soviet Union and NATO relations have changed, detection needs have fluctuated. An increase in the number of diesel electric submarines under the flag of third world nations has led to an increase in the interest in active sonobuoys and shallow water detection techniques. Sonobuoy Tech Systems offers a full line of sonobuoys and technical support to address modern Anti-Submarine Warfare (ASW).
Sonobuoys with different characteristics other than those described can be designed and built to customer requirements, following a careful analysis of needs. Sonobuoy TechSystems has designed and manufactured many sonobuoy variations over the years, and continues to make high-performance, high-reliability sonobuoys.
