Tactical adaptation is one of ten principles in naval warfare and listed in Swedish Doctrine for Naval Tactics from 2010. All levels of command can use tactical adaptation and uses it to reach the goal with the battle. Behind tactical adaptation, technology in relationship with tactics as a concept works together to support the tactical adaptation. This thesis aims to identify factors from theories about technology and tactics and to see how those factors affect the tactical adaptation in different cases. Known theorists as Van Creveld, Lauten- schläger and Hughes is used to form a tool for analyzing different cases. Factors derived from the three theorists is used in a qualitative case study consisting of the Yom Kippur-war and the Falkland campaign. Factors as combinations, flexibility, logistics, organization, secrecy, knowledge and further development was identified in the cases, but the factor development was nowhere to be found. The conclusions drawn from the analysis is that all factors accept development is useful and supports successful tactical adaptation.
