A gripping history that spans law, international affairs, and top-secret technology to unmask the tension between intellectual property rights and national security.
 
At the beginning of the twentieth century, two British inventors, Arthur Pollen and Harold Isherwood, became fascinated by a major military question: how to aim the big guns of battleships. These warships—of enormous geopolitical import before the advent of intercontinental missiles or drones—had to shoot in poor light and choppy seas at distant moving targets, conditions that impeded accurate gunfire. Seeing the need to account for a plethora of variables, Pollen and Isherwood built an integrated system for gathering data, calculating predictions, and transmitting the results to the gunners. At the heart of their invention was the most advanced analog computer of the day, a technological breakthrough that anticipated the famous Norden bombsight of World War II, the inertial guidance systems of nuclear missiles, and the networked “smart” systems that dominate combat today. Recognizing the value of Pollen and Isherwood’s invention, the British Royal Navy and the United States Navy pirated it, one after the other. When the inventors sued, both the British and US governments invoked secrecy, citing national security concerns.
 
Drawing on a wealth of archival evidence, Analog Superpowers analyzes these and related legal battles over naval technology, exploring how national defense tested the two countries’ commitment to individual rights and the free market. Katherine C. Epstein deftly sets out Pollen’s and Isherwood’s pioneering achievements, the patent questions raised, the geopolitical rivalry between Britain and the United States, and the legal precedents each country developed to control military tools built by private contractors.
 
Epstein’s account reveals that long before the US national security state sought to restrict information about atomic energy, it was already embroiled in another contest between innovation and secrecy. The America portrayed in this sweeping and accessible history isn’t yet a global hegemon but a rising superpower ready to acquire foreign technology by fair means or foul—much as it accuses China of doing today.

When President Eisenhower referred to the “military–industrial complex” in his 1961 Farewell Address, he summed up in a phrase the merger of government and industry that dominated the Cold War United States. In this bold reappraisal, Katherine Epstein uncovers the origins of the military–industrial complex in the decades preceding World War I, as the United States and Great Britain struggled to perfect a crucial new weapon: the self-propelled torpedo.

Torpedoes epitomized the intersection of geopolitics, globalization, and industrialization at the turn of the twentieth century. They threatened to revolutionize naval warfare by upending the delicate balance among the world’s naval powers. They were bought and sold in a global marketplace, and they were cutting-edge industrial technologies. Building them, however, required substantial capital investments and close collaboration among scientists, engineers, businessmen, and naval officers. To address these formidable challenges, the U.S. and British navies created a new procurement paradigm: instead of buying finished armaments from the private sector or developing them from scratch at public expense, they began to invest in private-sector research and development. The inventions emerging from torpedo R&D sparked legal battles over intellectual property rights that reshaped national security law.

Blending military, legal, and business history with the history of science and technology, Torpedo recasts the role of naval power in the run-up to World War I and exposes how national security can clash with property rights in the modern era.
