This report has been produced by the project Support to military strategic direction (SMI) on assignment from the Swedish Armed Forces and the long term defence planning process specifically, which also has directed the specific areas to address.In this report FOI presents some technology areas of interest for future warfighting. The purpose of the report is to inform on future technological developments out to 2045 for use in the Armed Forces long term defence planning process and its work on futures in particular. In this report the areas of additive manufacturing, cyber and information security, distributed ledgers, High Power Microwave (HPM), hypersonic systems, information technology, quantum technology, nuclear weapons, laser, human performance optimization/enhancement, unmanned and autonomous systems, platforms, space, signature management and the soldier system are addressed in short chapters. Each chapter is written by FOI researchers with long experience in the specific areas. In each chapter a general introduction and trends out to 2045 introduces the reader to the area. Thereafter specific technologies of relevance and interdependencis are presented. Military consequences as effects on capability and actors pursuing research and/or development activities in the area closes the chapter. The introductory and final chapters, written by the editors, describe the technology development in general terms, discuss the content of the report, draw conclusions and present ideas for future work This report can be used to identify questions of relevance for future military capabilities depending on technological developments. The time perspective, that is, how long into the futures one can anticipate vary between technology areas. The year 2045 is thus the longest timespan and most chapters present developments that are possible already 5 to 10 years into the future. Wargaming, workshops and reporting on additional technology areas are examples of possible continuing activities based on the information presented in this report. The editors encourage technical experts and military experts to meet, wargame and discuss issues raised by technology developments to better anticipate and prepare for future capability development.
