The results of the New Jersey effort are shown, with sam- ple documentation, the ship char- acteristics, and the downstream design effort. 9:45 a.m. "The Ship Characteristics and Improvement Board—A Status Report," by Stuart Williams. On September 7, 1982, Adm. W.N. Small, the VCNO, signed a memo establishing the Ship Char- acteristic and Improvement Board (SCIB). This memo ended months of deliberation between NAVSEA, NAVMAT, and OPNAV on how ship characteristics should best be developed and approved for both ship acquisition and fleet modern- ization programs. By tracing the history of char- acteristics decision-making for na- val ship programs, this paper es- tablishes the foundation of the present SCIB. Organizational ele- ments of the SCIB, including the functions of its permanent staff and working groups, are ex- plained, and the recent track re- The 1984 Annual EQUIPMENT CATALOG The World's Most Complete Annual Marine & Naval Equipment Catalog For Vessel Owners, Shipbuilders, Marine Designers, Naval Architects and Purchasing Agents.

Until it's too late. That's why it's wise to assume that your rudder bearings will always be getting rough treatment. Then you can prepare for it. With Thordon installed. Whether it's at the pintle, the stock or the steering gear, Thordon delivers better perform- ance than anything else you're using now. Consider shock-resistance. A sudden impact that would crack a phenolic or deform a bronze bearing has no effect on Thordon. It absorbs the shock and bounces back. Consider steering torque. It's less with Thordon, thanks to its lower co-efficient of friction. Consider service, Thordon raw stock is warehoused in 50 countries around the world. So wherever there's a Thordon distributor and a lathe, there's a Thordon rudder bearing. Cut the odds on premature rudder bearing failure. Get all the facts on Thordon, and start betting on a sure thing. ThfjrrJriri IT UJ0RK5 HARD. VOU RE5T EASY. WRITE FOR COMPLETE PERFORMANCE DETAILS TO: (J) WAUKESHA BEARINGS CORPORATION P.O.

James D. Ert- ner, USN, and Cdr. W.A. Tyler Cassedy, USN. A synopsis of Canada's unified (combined Army, Navy, and Air Force) defense organization and decision-making structure is pre- sented. This is followed by an ex- planation of the closely inter- twined Program Management and Life-Cycle Management Systems, and their relationship in the Ca- nadian ship design process. Next, U.S. Navy ship design procedures, including recent changes in pro- gram initiation procedures and creation of the SCIB, are viewed. Finally, the Canadian Department of National Defense and the U.S. Navy's design and acquisition pro- cesses are compared. Diplomat Room—Session IB Ship Auxiliary Systems Moderator: Capt. George M.

Raupuk Jr. Most U.S. Navy ships have sew- age collection, holding, and trans- fer systems that use conventional gravity-flush fixtures and a sea- water flushing medium. This type system is relatively simple but is inherently heavy and bulky, and is totally dependent of shore sup- port when used in port. Some re- cently designed Navy ships, the DD-963 and DDG-993 Classes, em- ploy a vacuum collection, holding, and transfer system (VCHT) that uses reduced-volume flush com- modes and urinals with either fresh water or seawater flushing and vacuum for waste transport. This system is light, compact, highly shore-independent, and provides significant system design flexibility. This paper traces the evolution of Navy shipboard sewage systems from the original gravity collec- tion system through the DD-963 Class VCHT system that used vac- uum pumps, to a new and promis- ing vacuum collection system that uses a sewage-powered eductor. 9:45 a.m. "FFG-7 Class Fin Stabilizer Sys- tem," by Cdr.
