The command and control system problem associated with the battle group, an ad hoc assemblage of naval resources, with the mission of achieving a predetermined objective as assigned by higher authority, is discussed. After restatement of the problem, criteria for evaluating system concepts are proposed. Emphasis is placed on combat environments. A concept for development of a battle group command and control system consistent with existing command philosophy and functional partition is presented. The philosophic principle is command by exception in a multi-hierarchical structure. Functional partition into warfare areas such as ASW, AAW, and ASUW provides the basis for the multiple branches of the hierarchy. Finally, the system criteria are applied to the battle group command and control concept presented herein. The resulting evaluation demonstrates that the conceptual system is readily implementable and can meet battle group operational needs.

ADAMS, JDBEVERLY, WFJohn D. Adams:is currently Manager of Marine Programs at Maritime Dynamics
Inc. Tacoma Washington. He received his B.S.E. degree in naval architecture and marine engineering from the University of Michigan in 1972. His professional career began at Stevens Institute of Technology working as a research engineer in the Davidson Laboratory where he conducted model test programs of both conventional and advanced ships. Some of his responsibilities included hydrodynamic model testing of the Navy SES-100A and SES-100B testcraft and the early 2000-ton and 3000-ton SES designs. In 1975 he accepted a position as Director of Maritime Dynamics' field activities at the USN Surface Effect Ship Test Facility where he had responsibility for SES-100A trials analysis. While at SESTF he directed several unique programs including the development of an experimental Ride Control System for the XR-1D SES testcraft. At his present position since 1982 Mr. Adams has directed the development of a production SES Ride Control System the SES-200 trial analysis and analytical research and design studies for SES. He is a member of ASNE and SNAME. Walter F. Beverly III:is Test Director of the lead Landing Craft Air Cushion for Bell Aerospace in Panama City
Florida. He has worked with surface effect ships (SES) for over ten years in various roles: SESTF. Past assignments included: Technical Director of the Navy Surface Effect Ship Test Facility (SESTF) Project engineer on the world's fastest warship the SES-100B and Program Manager's representative and T&E manager for the 3KSES Program in San Diego. Prior to his involvement with SES he was a flight test engineer at the Naval Air Test Center Patuxent River Maryland and graduated from the USN Test Pilot School test project engineering curriculum. Mr. Beverly received his BS in aerospace engineering from Virginia Polytechnic Institute in 1970 and his MS in systems management from the University of Southern California in 1977. He is a member of the American Institute of Aeronautics and

Recent Navy surface effect ship (SES) research has been aimed at achieving efficient operation at task force speeds without compromising the SES advantage of operating at higher speeds. Results showed that this objective could be achieved by designing ships with higher length-to-beam ratios than the previous generation of Navy SES. These ships are typically referred to as “High Length-to-Beam SES”. This paper describes an extensive program undertaken by Naval Sea systems Command (NAVSEA) to validate this research and demonstrate high length-to-beam SES capabilities. Under this program a 110 ft commercial SES was procured and stretched from a length-to-beam of 2.65 to 4.25 by installing a 50 foot hull extension amidships. This ship is the SES-200; it is the only large high length-to-beam SES in the world. A brief history of the SES-200 is provided, and the use of standard marine construction and systems in this ship is described. A synopsis of the SES-200 Technical Evaluation Program completed in the Chesapeake Bay and Atlantic Ocean is given, and results of performance, seakeeping and maneuvering tests are presented. The effect of cushion length-to-beam proportions on both cushion wave making resistance and total SES resistance is explained. Performance test data are presented to show that the advantages of high length-to-beam design have been validated. Full power operation in heavy weather at all headings is demonstrated, and heavy weather motion responses are compared to Navy surface ship criteria to show that limits are satisfied for both high and low speed operation. Directional stability and maneuvering test results are cited for both normal operation and impaired situations. Implications of high length-to-beam technology relative to multithousand ton ship design are discussed. The speed and seakeeping capabilities that SES in this size range offer are indicated by scaling SES-200 test data.

This paper presents an integrated approach to Computer-Aided Ship Design for U.S. Navy preliminary and contract design. An integrated Hull Design system (HDS), currently under development by the Hull Group of the Naval Sea systems Command (NAVSEA 32). is the vehicle for the discussion. This paper is directed toward practicing ship design professionals and the managers of the ship design process. Primary emphasis of this paper, and of the development effort currently under way, is on aiding ship design professionals in their work. Focus is on integration and management control of the extremely complex set of processes which make up naval ship design. The terminology of the Ship Designer and Design Manager is used. The reader needs no familiarity with the technologies of computer science.

Using the common procedure of having each team member in two-man teams check the interpretations of his teammate, three experiments centered around the following questions: (1) How much knowledge should the checker have of the initial interpreter's work? (2) How accurately can the initial interpreter rate the accuracy of his interpretations and can the initial interpreter effectively designate which of his interpretations need checking? And, (3) how can a third interpreter best be utilized to resolve conflicts in interpretations made by the original two-man team? Variations centered about the amount of information passed from initial interpreter to checker, discussion between team members versus no discussion, consensus versus one-man decision in determining the team product, confidence ratings made by interpreters and confidence levels below which interpretations were checked, and participation of a third team member under varying conditions to resolve conflicts in interpretation. Results were evaluated in terms of completeness of information extracted, accuracy and efficiency.

Connected Autonomous Vehicle (CAV) Driving, as a data-driven intelligent driving technology within the Internet of Vehicles (IoV), presents significant challenges to the efficiency and security of real-time data management. The combination of Web3.0 and edge content caching holds promise in providing low-latency data access for CAVs’ real-time applications. Web3.0 enables the reliable pre-migration of frequently requested content from content providers to edge nodes. However, identifying optimal edge node peers for joint content caching and replacement remains challenging due to the dynamic nature of traffic flow in IoV. Addressing these challenges, this article introduces GAMA-Cache, an innovative edge content caching methodology leveraging Graph Attention Networks (GAT) and Multi-Agent Reinforcement Learning (MARL). GAMA-Cache conceptualizes the cooperative edge content caching issue as a constrained Markov decision process. It employs a MARL technique predicated on cooperation effectiveness to discern optimal caching decisions, with GAT augmenting information extracted from adjacent nodes. A distinct collaborator selection mechanism is also developed to streamline communication between agents, filtering out those with minimal correlations in the vector input to the policy network. Experimental results demonstrate that, in terms of service latency and delivery failure, the GAMA-Cache outperforms other state-of-the-art MARL solutions for edge content caching in IoV.
