AN/SQS-26 was a United States Navy surface ship, bow mounted, low frequency, active/passive sonar developed by the Naval Underwater Sound Laboratory [1] and built by General Electric and the EDO Corporation. At one point, it was installed on 87 [2] US Navy warships from the 1960s to the 1990s and may still be in use on ships transferred to other navies.

Contents

In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/SQS-26" designation represents the 26th design of an Army-Navy electronic device for surface ship sonar search system. The JETDS system also now is used to name all Department of Defense electronic systems.

Capabilities

The AN/SQS-26 weighed 27,215 kg (59,999 lb). It could be operated as a passive sonar on the 1.5 kHz frequency or as an active sonar at 3–4 kHz. Its maximum output was 240 kW and it had a range from 18 to 64 km (11 to 40 mi). It had direct path, bottom reflected, passive and convergence zone (CZ) capabilities. [3]

Variants

The original AX sonars were manufactured by General Electric Heavy Military Electronics. The "R" suffix was the result of a "Retrofit" by GE that incorporated improved designs derived from the AN/SQS-26CX sonar, also manufactured by GE.

BX sonars were manufactured by EDO Corporation.

CX sonars were manufactured by General Electric Heavy Military Electronics. AN/SQS-26CX sonar performs a 360-deg, long-range sector search at low frequency. [4]

AN/SQS-53

AN/SQS-53 is an improved version of AN/SQS-26CX. The main difference between the SQS-26CX and SQS-53 sonars is the digital computer interface with the Mk 116 anti-submarine warfare (ASW) weapon control system in the latter. [4] In addition, AN/SQS-53 sonar can be fitted with the Kingfisher small obstacle (mines) avoidance sonar. [4]
