Blount To Design And Build

Research Vessel For Raytheon

Raytheon Company announces the award of a contract to Blount Marine Corporation of

Warren, R.I., for design and construction of an 81-foot oceangoing research vessel. The welded steel and aluminum craft will be under management of Raytheon's Submarine Signal

Division at Portsmouth, R.I. for sonar develop- ment, as well as for survey and development work in oceanography and the environmental sciences.

In construction and fitting, the twin-screw vessel will be the most modern for her size and mission in the United States. Two Gen- eral Motors 350-hp diesel propulsion engines will be specifically adapted for silent operation by means of a new system recently pioneered by Blount. Acoustic isolation of her two large diesel power generators will also enhance the use of underwater sound techniques for many applications, such as bottom and sub-bottom mapping and the command and control of en- vironmental sensors.

Raytheon Company and Blount Marine Corporation sign contract for new research vessel construction. Shown above, (seated) left to right, are: Ralph A. Martin, vice president Raytheon Company and general manager, Sub- marine Signal Division, Portsmouth, R.I., and L.H. Blount, president Blount Marine Corporation, Warren, R.I., and (standing) left to right, Richard A. Elliott, purchasing de - partment, Submarine Signal Division, Raytheon Company, and Frank G. Crawford, engineering department, Subma- rine Signal Division, Raytheon Company. The contract is for construction by Blount Marine Corp. of an 81-foot steel and aluminum craft to be bulit for operation of

Raytheon Company's Submarine Signal Division.

The vessel will be provided with a spacious laboratory area to accommodate the increas- ing number and diversity of Raytheon's off- shore activities. Typically, the seagoing lab will support the operation of the company's

Ocean Systems Center under a multiyear Sea

Grant program to develop survey systems and techniques for improved knowledge and use of continental shelf resources. Scientists and en- gineers of the Portsmouth Division will use it to conduct studies of underwater sound propa- gation under actual sea conditions, and evalu- ate experimental designs for improved subma- rine detection systems. The laboratory will provide facilities for investigation of the phy- sical, chemical and biological causes of bay pollution and the development of water quality monitoring systems by Raytheon's Environ- mental Systems Center.

A special electronics room in the custom-de- signed vessel will serve to demonstrate new equipment and systems, including those de- veloped by Raytheon's Marine Products Oper- ation of Manchester, N.H., for commercial shipping and pleasure boats.

The vessel will operate primarily in coastal waters of the Atlantic. She will have a nonstop cruising range of 2,640 miles at 10 knots, and modern quarters for 10 people in crew and project scientists and engineers. Construction and outfitting is expected to require five months, with delivery on June 30, 1971.
