War in Heaven

"War in Heaven" by Fletcher Pratt is a science fiction exploration of space warfare written during the early 1950s. The book delves into the strategic, tactical, and technological aspects of potential space battles, offering insights into the feasibility of various weapons and ship designs. With Pratt's background as a military and naval historian, the narrative presents a well-researched speculation on how such conflicts might unfold, shedding light on the constraints of physics in outer space. The text discusses various concepts related to space vessels, including their shape, armament, and the unique challenges of maintaining air supply for the crew. Pratt argues for the superiority of spherical ships for maneuverability and safety, and critiques conventional ideas like death-rays and torpedoes, advocating instead for solid projectiles and guns that accommodate the vacuum of space. He examines the importance of establishing bases on celestial bodies like the Moon and asteroids for resource extraction and as strategic points in a wider campaign. Overall, "War in Heaven" serves as a thoughtful treatise on future military engagements beyond Earth, balancing imaginative scenarios with grounded scientific reasoning.
