Raytheon's 'Sub Sig II' To Provide Sea Trial Support For Electric Boat

Contractor sea trials of submarines built by General Dynamics' Electric Boat Division, Groton, Conn., will be supported by Raytheon Company's research vessel Sub Sig II under terms of a charter signed recently by the two firms.

The vessel, owned and operated by Raytheon's Submarine Signal Division, Portsmouth, R.I., will provide positive keeping, communications, and other on-site services required to test and evaluate underway performance of new attack and ballistic missile submarines prior to their acceptance by the Navy. The renewable oneyear agreement also requires performance of similar services for other submarine builders if requested by the Navy.

The position of a submarine during submerged maneuvers will be maintained continuously by a Raytheon DE1167 sonar system, designed and built at Portsmouth for small ASW patrol ships. Comprehensive sea tests of the system and various navigation and communications equipment were conducted in the 118-foot Sub Sig II to demonstrate a total capability to satisfy the highly precise data requirements of the trials.
