The USS Tortuga at the Shipyards Division of Avondale Industries, Inc., Avondale, La. She is the third in a series of five Landing Ship Docks (LSDs) being built for the U.S. Navy. The
Tortuga is powered by four medium-speed Colt-Pielstick diesel engines.

USS Tortuga (LSD-46) For Navy
Third In Series Built By Yard
Promising Future For
Canadian Shipbuilding (continued) with Hyperfix Precise Navigation
Systems, side scan sonar, the PINS 9000 Precise Integrated Navigation
Systems and with mechanical mine- sweeping equipment.
The two vessels will require dock- ing, equipment installation and shipwork to bring them to Canadian
Coast Guard pollution standards.
The DND will contract engineer support to private industry within the next six months.
This project is presently in the planning stages. When developed, it will entail the progressive modifica- tion and replacement during the 1990s of tugs, cranes and auxiliary barges. This project should generate a great deal of work for Canadian yards.
The urgency of the Canadian Pa- trol Frigate requirement for a trials support vessel has made it necessary for the DND to bring forward the procurement of one of the vessels in the Auxiliary Fleet Replacement
Project, the General Purpose Auxil- iary Vessel. This vessel is needed much the same as the MCM Auxil- iary, and Supply and Services Cana- da has sent letters to all companies who responded to the MCMA re- quest.
This project involves the installa- tion of a modern, fixed under-ice surveillance system in the Arctic to aid in the detection of incursion of
Canadian Arctic waters by subma- rines. Departmental officials are in the process of preparing the neces- sary option analysis and documen- tation to obtain approval for this project. It is expected that a com- petitive contract for project defini- tion will be issued in 1989.
The DND has determined the need for mobile-subsurface long range surveillance systems consist- ing of towed arrays and up to three towing vessels. This project depends on the development of a suitable sensor to meet the performance re- quirements.
ASW Patrol Frigates
The government has approved the second phase of the ship re- placement program in the form of six more Canadian patrol frigates to be delivered between 1992-1996.
The design remains essentially the same as that of the first six ships and Saint John Shipbuilding, Ltd.,
New Brunswick, and Paramax are in the process of placing purchase orders for material for the second batch.
At a total cost of C$10 billion, the
CPF is the largest single defense project with annual expenditures now approaching C$1 billion.
Saint John Shipbuilding, the prime contractor for the first six fri- gates, has christened the first ASW frigate, the HMCS Halifax, and will construct two others.
Marine Industrie Limitee (MIL) of Quebec is building the other three frigates in the first batch.
Tribal Class Update &
Modernization Project (TRUMP)
The C$1.2-billion TRUMP pro- gram was begun in June 1986 when
Litton Systems Canada Ltd. was selected as prime contractor with responsibility for project manage- ment and combat systems design and integration.
Under the project, the four Tribal
Class destroyers, the Iroquois, Al- gonquin, Huron and Athabaskan, are being modernized and equipped with new combat systems, gas tur- bine propulsion engines, diesel gen- erator engines, vertical missile launcher modules and electronics to fulfill the role of air defense, as well as antisubmarine warfare. Each conversion takes approximately 18 months.
At present, the HMCS Iroquois and the HMCS Algonquin are being converted at the MIL Davie Ship- yard in Lauzon, Quebec.
Contracts for the second two de- stroyers will be let by Litton on a competitive basis. The RFP was issued by Litton in 1987 and propos- als have been submitted. The evalu- ation and approval process is pro- ceeding and it is expected that the subcontract will be awarded early this year.
CF Maritime Experimental & Test Range Support Vessels
West Coast Manly, a division of
Rivtow Straits Ltd., was awarded a contract in September 1988 to build four Canadian Forces Experimental and Test Range Support vessels.
The vessels will be 98.4 feet long and displace about 220 tons.
Research & Development
This year, the Research and De- velopment Branch of the DND has been allocated C$149 million for
R&D contracts and equipment, plus the support needed for research fa- cilities. These funds will be supple- mented by additional monies identi- fied to support international coop- erative development as recently stipulated by the U.S. "Nunn
Coast Guard Projects
A number of Canadian Coast
Guard major capital projects have been completed, are underway or proposed. See Exhibit 1 for details.
More information will be provided next issue. •
USCG Buoy Tender
Bender Shipbuilding & Repair
Co., Inc., Mobile, Ala., was recently awarded a $278,546 contract for the regular overhaul of the U.S. Coast
Guard buoy tender Salvia.
Contingent work on the 180-foot tender, which is based at the Coast
Guard station in Mobile, could add $100,000 to the contract.
Avondale Shipyards Division,
Avondale Industries, Inc., Avon- dale, La., recently christened the
Landing Ship Dock vessel USS Tor- tuga (LSD-46) for the U.S. Navy.
She is the third in a series of LSDs being built for the U.S. Navy by the yard.
The principal speaker at the christening ceremonies was U.S.
Senator J. Bennett Johnston (D-
La.). The ship's sponsor was Mrs.
Rosemary Parker Schoultz, wife of retired Vice Adm. Robert
F. Schoultz, U.S. Navy. Other dig- nitaries at the ceremonies included
Albert L. Bossier Jr., chairman and chief operating officer, Avon- dale Industries, Inc., and the Honor- able Everett Pyatt, Assistant Sec- retary of the Navy, Shipbuilding and Logistics.
The USS Tortuga, like her sister ships, is 610 feet long, has a beam of 84 feet, maximum draft of 19 feet 7 inches, and displaces 15,623 long tons.

Engineering medium-speed diesel engines for a total of 33,000 shp, the Tortuga is capable of service speeds in excess of 20 knots.
LSDs are multi-functional ships capable of a wide range of amphi- bious assault operations for the U.S.
Navy and Marine Corps. Their pri- mary mission is to carry, launch and dock up to four Landing Craft, Air
Cushion (LCAC) vessels. In combi- nation with the LCACs, the LSD ships will allow Marines to make beach landings.
The LCACs which will be carried by the Tortuga and her sister LSDs are also being built by Avondale at its recently acquired Gulport ma- rine facility.
The Tortuga, which is being built by Avondale with the use of mod- ular construction techniques, is ex- pected to be delivered in July 1989.
