The US Navy has awarded a contract to SyQwest to renovate the navy’s attack class submarine electronics.

Under the $9.7m contract, the company will repair, restore and replace large spherical array (LSA) and wide aperture array (WAA) outboard electronic bottles (OBE) used on attack submarines.

The OBE is an inbuilt part of the submarine sonar system while each LSA and WAA OBE contains electronics to provide amplification, filtering, analogue-to-digital conversion and signal encoding.

Transmission of all hydrophone channels’ digital acoustic data within the OBE to the inboard sonar system processing electronics are done enroute serial data lines.

The five-year contract has been awarded by the Naval Undersea Warfare Center in Newport, Rhode Island.
