Marinette Marine Awarded $6-Million Navy Contract Marinette Marine Corporation has been awarded by the Naval Sea Systems Command a contract modification for the construction of three additional Torpedo Weapon Retrievers. Total value of the con- tract modification exceeds $6 million. The three vessel option is a part of an existing contract for the con- struction of five TWR's which was awarded to MMC in July of this year. The TWR class vessel is a to- tally new design developed by Marinette Marine to replace the Navy's aging existing TWR ves- sels. The TWR craft are utilized by the Navy for recovering spent tor- pedoes, missiles, small drones and mobile targets fired during weap- ons systems tests of all subma- rines and combatant ships. The newly designed vessel is capable of staying on station for a week in support of these tests, thus avoid- ing long delay times for ships, caused in the past by smaller boats having to return to base at night and then return to the test site the next day. The TWR vessel will be 120 feet in length with a beam of 25 feet, depth of 12 feet and approximate displacement of 213 tons. Accom- modations are provided for a com- plement of 18 persons. The vessel is entirely steel construction, 2,000 hp, with twin screws driving fixed- pitch propellers. The TWR has a design speed of 16 knots and a range of 1,700 nautical miles. Construction on the TWR con- tract begins in late 1983, while de- livery of the three additional TWR craft is scheduled to begin in July of 1985. Literature Available On TeleSystems' Newest Marine Communications System The new MSC-9000 Maritime Communications System from TeleSystems, a COMSAT com- pany, is a shipboard satellite ter- minal offering telephone, telex, data, and facsimile transmission capability with automatic tuning to all 339 available channels. It is designed to meet or exceed all MARISAT and INMARSAT specifications. Years of experience in the de- sign, installation, and mainte- nance of MARISAT terminal equipment have contributed to the evolution of the MCS-9000, result- ing in a compact system that was designed with present and future needs in mind. The system is com- pact, versatile, and flexible, with high reliability, low life cycle costs, and ease of operation.
