<p>Några av de stora sjöteoretiker som vi utbildas på idag var verksamma i en tid innan insatsförsvaret, men deras teorier anses fortfarande vara användbara idag. Idag genomför svenska flottan andra typer av insatser än på slutet av 1800-talet, då teoretikerna Mahan och Corbett var verksamma. Kriget ser inte likadant ut idag och både tekniken och taktiken har utvecklats. Är de teorier vi utbildas på, tillämpbara idag? Syftet med denna uppsats är att undersöka teorier om skydd av handelsfartyg och jämföra hur detta skydd genomförs i nutid med fokus på insatsen i Adenviken. Utgångspunkten har varit att genom kvalitativ textanalys beskrivit Mahans, Corbetts och Vegos teorier om skydd av handelstransporter. Dessa har jämförts med varandra samt med en fallstudie genomförd på Operation Atalanta. En av slutsatserna är att teoretikerna Mahan, Corbett och Vego har liknande teorier. De talar omsäkra hamnar, konvoj, eskort och säkra färdvägar som metoder att skydda handelstransporter. Skillnaden är hur metoderna genomförs samt hur viktiga de är. De metoder av Mahan och Corbett som återfinns i Operation Atalanta är framförallt eskort, men även vikten av säkra farleder och knutpunkter.

Today the Swedish fleet carries out other types of missions than in the late 1800s, when Corbett and Mahan were active. War does not look the same today as both technology and tactics have evolved. Are the theories we study, applicable today?The purpose of this paper is to examine theories about the protection of merchant ships and compare Mahans, Corbetts and Vego theories with how it is implemented in the present day, focusing on the operation of the Gulf of Aden. This paper uses qualitative text analysis to describe Mahan, Corbettand Vegos theories, on the protection of commercial shipments. These were compared with each other and the results were later applied to a case study on Operation Atalanta. One of the conclusions are that Mahan, Corbett and Vegos theories are similar, concerning securingports, convoy, escort and securing routes. The difference however is how to apply these methods and the importance of them. Mahan and Corbett's theories, which are applicable to Operation Atalanta concern escort, and the importance of safe routes and hubs. Vegos theories which are applicable are escorts and the importance of air supremacy for the protection of trade and transport to work with preventive measures.</p>

Since Russia´s annexation of the Crimean Peninsula, asymmetric warfare has been on the rise, and much effort has been focused on understanding and comparing this warfare to existing theories. This, however, has not been the case for the naval aspects of asymmetric warfare. Even though nations and insurgents alike use these methods it has received little focus and therefore many questions have been left unanswered.  How should naval asymmetric warfare be understood and countered? Does naval asymmetric warfare relate to existing naval theories or is it related to existing asymmetric land theories? This essay aims to answer some of these questions by using Vegos theory concerning sea control to examine asymmetric methods and their correlation to sea control in The Tanker War and the Sri Lankan civil war.  This essay concludes that asymmetric methods and it´s correlation to sea control are, to a great extent, described by Vegos theory. The methods used and level of sea control achieved conform to Vegos theory which, according to this essay, can be used to interpret asymmetric naval conflicts.

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.
