USS Willis A. Lee receives the first SQS-26-sonar in 1961.

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.

Capabilities[edit]

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[edit]

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.
