Efter murens fall ändrades den amerikanska maritima fokusering från att verka på öppet hav till att verka mer i de litorala områdena runt om i världen. Denna inriktning har föranlett införande av nya system vilket i sig föranlett en debatt främst inom den amerikanska flottan huruvida detta är relevant. Syftet med uppsatsen är att analysera hur fokusering på det litorala området uppstod och vilka konsekvenser detta medförde genom att studera hur fokuseringen formulerades i strategiska dokument och koncept.                 Resultatet visar på en strategisk strävan till hegemoni inom den amerikanska marinen. Detta har inte fullt lyckats då det spåras en antagonism kopplad till kampen om resurser och skillnader i identiteter. Uppsatsen visar på att inställningen till att verka i den litorala miljön skiljer sig åt mellan flottan och marinkåren där flottan uppfattar att verka litoralt är farligt och kommer att ge förluster medan marinkåren identifierar farorna men uppfattar miljön som sitt naturliga verkansområde.

Includes supplemental material. / This report outlines the results of a two quarter Total Ship Systems Engineering (TSSE) Capstone design project undertaken by the students at the Naval Postgraduate School. The project was under the direction of Professors C.N. Calvano and R.Harney. / Currently, no system exists that provides a sea-based distributed aviation platform capability. The emergence of Unmanned Air Vehicles (UAVs) / Unmanned Combat Air Vehicles (UCAVs), the continued U.S. Navy focus on the littorals, the desire for force distribution, the need for operational cost reductions, and the advent of Network Centric Warfare (NCW) all continue to support the requirement to re-evaluate how littoral operations will be conducted in the future. Given this background, a bottom-up design of a ship supporting a primarily UAV/UCAV air wing in a low to medium threat environment is of significant interest. SEA ARCHER meets this interest. This report outlines a design that meets the future needs for distributed aviation with a high-speed, highly automated platform. Large gains in reduced manning through automated systems for both operation and damage control helpmeet the demanding needs for the future of the Navy at reduced operational costs. The report will outline both the Mission Needs Statement (MNS) and Operational Requirements Document (ORD) for the ship that was developed. The analysis of alternatives that was conducted to determine relative size requirements for the ship in presented in the next section. The concept design that resulted as a result of the Total Ship Systems Engineeing process in then presented. Finally, a detailed look at the analysis and trade studies that were conducted in presented in order to show the more detailed analysis that was conducted in designing the ship.

Denna uppsats undersöker huruvida vi med hjälp av Gustav von Schmalensees modifikation av Lanchesters kvadratiska N2-Law kan bestyrka eller falsifiera teorin att en kustflotta med hjälp av en amfibisk miljö kan slå en på pappret överlägsen motståndare. Den komplexa miljö som en kustremsa eller skärgård utgör påverkar en högsjöflottas kapacitet att utgöra ett hot mot en kustflotta vars taktik är anpassad för terrängen och de synergieffekter som den ger. Uppsatsen försöker påvisa hur stor inverkan variabeln geografi har i sammanhanget. Vidare undersöker uppsatsen huruvida det är möjligt att förbättra von Schmalensees modifikation av Lanchesters N2-Law med hjälp av den faktiska sannolikheten för träff med sjömålsrobot inomskärs respektive utomskärs. Med hjälp av Försvarshögskolans sjökrigsspel Simple Surface Warfare Model (SSM) genomförs ett experiment där teorierna testas empiriskt. Resultaten visar en förbättring i prediceringen av stridsutfall med sjömålsrobot om koefficienten för den faktiska sannolikheten för träff räknas in i ekvationen. Vidare konstateras att en stark korrelation kan ses i en mindre kustflottas överlevnad i amfibisk miljö då de möter en på pappret överlägsen motståndare.

Approved for public release; distribution in unlimited. / In Littoral Warfare (LW), naval operations face a whole new range of missions and types of threats. In such situations, Electronic Warfare (EW) systems are extremely important, yet constantly challenged to perform faster and more accurate detection and recognition of potential threats. However, meteorological and oceanographic (METOC) factors can severely modify the effectiveness of EW systems, particularly against low detectable targets in warm waters. Therefore, this thesis analyzes the effects of tropical littoral environments in the expected performance of generic RF and IR systems when used under these scenarios. It analyzes the outputs of propagation models included in the software suites AREPS and TAWS when using actual data from different sources in the Yucatan Channel. The results of this study demonstrated how radically the environmental conditions can change, clearly modifying the efficiency of surveillance and detection systems in shipborne platforms. Further, several issues related to the need of valuable data and additional research are addressed, while providing useful insights to operational commanders and decision makers for the use of EW systems and available Tactical Decision Aids (TDAs) at the typical scenarios of Littoral Warfare in tropical waters. / Lieutenant Commander, Mexican Navy

Defending against a modern amphibious landing is one of the most difficult operations in warfare. Many have tried but very few have succeeded to throw an assaulting landing force back into the sea. This essay is an attempt to create deeper understanding for anti-landing defense by using Milan Vego’s theory on littoral warfare in a case study of the landings in Salerno 1943 and on Okinawa 1945. This is in order to examine if this theory on marine warfare in coastal regions can be used to create deeper understanding for defense against a modern amphibious assault. With a current trend towards increasing military interests in littoral regions, this essay intends to bring an up-to-date contribution to the theoretical foundation of marine warfare in littoral regions, and more specifically coastal defense.   The analysis shows that Vego’s theory did create deeper understanding of the two cases and particularly regarding command, inter-service cooperation and sea control or sea denial. These concepts have in both cases proven successfully practiced by the assaulting force, while the defenders have failed to benefit from them.

Littoral warfare implies a disproportionate advantage to the coastal navy or “defending” side. Small navies sometimes lean on larger navies in doctrinal production. A coastal navy’s goals, methods and capabilities can be considered thought to be different from that of a larger navy’s regarding in regards to littoral warfare. This paper answers the question “What does littoral warfare mean for different types of states?”. An ideal type analysis was used to answer the question, and the doctrines of Sweden (type A state), USA (type B), and the UK (type B) were analysed in regards to the research question. This paper found inds that each type of state viewed littoral warfare in regards to themselves, from their own perspective; a type A state can be seen as a defender and a type B state as an aggressor. In the context of littoral warfare context, each the types of states employed different goals, methods and means as pertaining to littoral warfare.
