Marinette Marine Awarded $7-Million Navy Contract For Two Additional TWRs

Marinette Marine Corporation of Marinette, Wise., has been awarded a contract by the Naval Sea Systems Command for the construction of two Torpedo Weapons Retriever (TWR) boats. The Wisconsin shipyard had previously been awarded in 1983 a Navy contract for eight vessels of this class.

The TWR class vessel is a totally new design developed by Marinette Marine to replace the Navy's aging existing TWR vessels. These craft are utilized by the Navy for recovering spent torpedoes, missiles, small drones, and mobile targets fired during weapons systems tests of all submarines and other combatant ships. The newly designed TWR is capable of staying on station for a week in support of these tests, thus avoiding the long delay times for ships caused in the past by smaller boats that had to return to base at night and then return to the test site the next day.

The TWR vessel is 120 feet in length with a beam of 25 feet, depth of 12 feet, an approximate displacement of 213 tons. The craft is entirely steel construction with a total propulsion power of 2,000 bhp driving twin fixed-pitch propellers. Design speed is 16 knots and range is 1,700 nautical miles.

Delivery of the first two TWRs ordered in 1983 is scheduled for spring this year; the two vessels in the new award are expected to be delivered in June 1986.
