Document Introduction

This report originates from the Stockholm International Peace Research Institute's classic 1978 study, systematically examining the increasingly prominent trend of space militarization during the early space age (up to the mid-to-late 1970s). The core issue of the report is to explore whether and how outer space might evolve into "the battlefield of the future," providing a detailed foundation of technical and program analysis for this purpose.

The report first outlines the massive military space programs of the United States and the Soviet Union. By the end of 1976, 1,386 known military satellites had been launched, with the US and USSR accounting for the largest share. The report notes that although public attention was largely focused on the peaceful uses of space, approximately 60% of US and Soviet satellites served military purposes, covering reconnaissance, communications, navigation, meteorology, early warning, and even anti-satellite capabilities, with enormous cumulative costs. This context shattered the early post-1967 Outer Space Treaty fantasy of space as a "zone of peace," as the treaty only prohibited placing weapons of mass destruction in orbit and did not restrict other military activities.

Structurally, the report follows a rigorous technical analysis path. Chapter Two explains the basic principles of satellite orbital dynamics and perturbations, providing the foundation for understanding the mission design and capability limitations of various satellites discussed later. Subsequent chapters delve into different types of military satellites: Chapter Three provides a detailed analysis of US and Soviet photographic and electronic reconnaissance satellites, including their orbital design, ground track calculation, resolution analysis, and demonstrates their practical application patterns in monitoring conflict zones using cases such as the 1974 Cyprus crisis; Chapters Four through Seven explore the military applications and respective program developments of communications, navigation, meteorological, and geodetic satellites.

The report's research methodology is primarily based on professional analysis of open-source information, particularly utilizing satellite launch data and orbital parameters provided by institutions like the Royal Aircraft Establishment, and monitoring of Soviet "Kosmos" series satellite signals by amateur observers (such as the team from Kettering Grammar School in the UK), to infer satellite mission types. The report concludes by assessing the role of satellites as "national technical means" for verifying compliance with arms control agreements, while also expressing concern about their "other side" potentially fueling military competition and technology proliferation. As a historical technical assessment, this document provides indispensable primary source material and a professional perspective for understanding the origins and early development of contemporary space security issues.
