Dive deep into the often-overlooked history of Unidentified Submerged Objects (USOs) with Volume 2 of Richard Dolan's comprehensive investigation. This book focuses specifically on global cases spanning the critical period from 1970 to 1989, a time characterized by increased frequency and intensity of encounters both above and below the waves. Drawing from extensive archival research, military reports, and civilian testimony, this volume challenges the marginalization of underwater UAP research.

Historian Richard Dolan meticulously examines reports of anomalous craft operating in Earth’s oceans, lakes, and rivers during the Cold War era. The evidence presented covers interactions involving both U.S. and Soviet naval forces, highlighting incidents that remain outside publicly acknowledged technological capabilities.

• Detailed investigation into Unidentified Submerged Objects (USOs) from 1970 through 1989.
• Examines striking incidents involving large objects moving without detectable propulsion or ascending from water with controlled acceleration.
• Analyzes encounters near shorelines, in open ocean, and in inland waterways.
• Includes reports of equipment disruption, physiological effects, and perceived time gaps associated with sightings.
• Places these persistent, widespread encounters within their specific historical context, including the impact of increased sonar and submarine technology during the Cold War.
