Dolphins are highly regarded because of their intelligent nature and social behavior and their capacity to use advanced sonar. The marine mammals extend their presence beyond aquariums and ocean documentaries through their participation in military research projects. People have raised doubts about the use of dolphins as surveillance animals and underwater security personnel since the past. The documented history that supports these claims will be examined in this section.
The Cold War Sparked Interest

The United States and the Soviet Union both investigated new underwater defense systems during the Cold War. The military showed interest in dolphins because their echolocation system provided natural detection abilities.
U.S. Navy Marine Mammal Program

The United States Navy established the Marine Mammal Program in the 1960s. The researchers investigated dolphin abilities to find underwater mines and track submerged objects on the ocean floor.
Why Dolphins Were Chosen

Dolphins possess highly advanced biosonars. The echolocation system enables them to find tiny objects which exist in unclear water at an accuracy level that exceeds basic mechanical sonar systems.
Mine Detection Missions

The official records document that dolphins which received training have helped find underwater mines during controlled missions. Their main job involved marking the locations of objects but they did not participate in combat.
Security Around Naval Facilities

Dolphins have reportedly been used to patrol restricted harbor areas. Their underwater movement detection system enables them to identify new objects which they have not encountered before.
Training and Conditioning

The program used positive reinforcement methods as its main training approach. Dolphins received rewards for identifying objects or returning to handlers after tasks.
Soviet Marine Mammal Research

The Soviet Union conducted research on marine mammals during its Cold War period. There are reports that claim dolphins were used for military research purposes which included similar studies to those done on dolphins.
Public Curiosity and Speculation

The media coverage and documents about the case led to public interest which created more powerful theories regarding the situation. The official documents of the organization support their ability to detect and recover various items.
Ethical Discussions

The military uses of intelligent marine mammals for their programs have created ongoing ethical discussions. Advocacy groups continue to monitor transparency and welfare standards.
Program Status Today

The U.S. Navy Marine Mammal Program has developed into a defensive system which includes mine detection and object recovery operations.
