description
The SQR-19 is part of the AN / SQQ-89 sonar system. It is inserted from a round exit opening on the ship's transom. The sonar covers a radius of 360 ° and can also be used at higher speeds and in seas up to strength 4. The cable length is 1,707 meters, whereby the system can be operated not only passively but also actively. The actual sonar complex, which can be lowered down to 365 meters, is 242 meters long and consists of 16 individual modules (eight for long wave (VLF) , four long wave (LF) , two medium wave (MF) and two short wave (HF) ) which works on a total of four frequency bands. At the beginning the AN / UYK-20 computer was used and from 1991 the AN / UYK-44 computer, which evaluates the data from the SQR-19. They were the largest and most complex program used in an anti-submarine system.
The first experiments and developments of the AN / SQR-19 began in 1982 on the destroyer USS Moosbrugger (DD 980) ( Spruance class ).
