ASNE Day (continued from page 51) carry out the mission. The ship characteristics are determined to match each of the ship alterna- tives including size, first cost, and life cycle cost. Then the task groups are put through a simulated mis- sion including enemy attack (de- fense by the group) and their of- fensive mission. The losses resulting from enemy action and the performance of the group in carrying out its mission are com- puted for the various enemy threats. Measures of effectiveness, both for the mission itself and the ship operating in a peacetime for- mat, are then determined.

The hand-wired, point-to-point cabling that has been the main- stay of data handling on naval ships is slowly but surely giving way to more advanced techniques that include data bussing and high- speed switching networks.
The Navy's AN/USQ-82(V)
Shipboard Data Multiplex System (SDMS) is now installed and oper- ating for technical and operational evaluation purposes on USS Old- endorf, a DD-963 Class destroyer.
The distributed switching system
SITACS introduced at ASNE Day 1982 has now been breadboarded.
In the foreign arena, NATO stand- ard bus-network interfaces are being implemented in Norwegian,
United Kingdom, and Canadian shipboard systems. These develop- ments are reviewed and projec- tions are made regarding future trends in naval data handling systems. 3:15 p.m. "Application of Fiber Optic
Technology to Combatant Subma- rines: Near and Far-Term," by
Ronald A. Swain and LCdr.
David C. Poyer, USNR-R.
Transmission of multiplexed data by means of optical fibers—pulses of light, conducted through chan- nels of glass—offers many advan- tages over conventional multiwire systems. Optical fiber is lighter, easier to run, cheaper to install, is fireproof and resists shock, and is inherently resistant to EMI and
EMP. It has been proven in com- mercial use.
Responding to these advantages, the Navy has for several years funded programs to provide mili- tary specifications for fiber optic (FO) connectors, couplers, splices, penetrators, sources, and detec- tors. This effort is near its success- ful end, and the Service has re- cently approved the first operational shipboard system. A fiber optic bus will carry data in the Submarine Advanced Combat
System to be installed in new ships of the SSN-688 Class sub- marine construction program. 4:00 p.m. "Ship Combat System Simula- tion (SCSS)," by Dennis R. Mensh.
This paper will describe a com- bat system integration and analy- sis tool called the Ship Combat
System Simulation (SCSS), which was designed as an analysis tool to study Sensor, Command and Con- trol, and Weapon System Integra- tion for shipboard combat systems.
The simulation represents the combat system components as nodes in a network. The nodes are connected by links. Data flows be- tween the nodes through the links.
The SCSS is a structured pro- gram simulation written in Sim- script II.5. The structured pro- 52 Circle 159 on Reader Service Card Maritime Reporter/Engineering News
