7. Orcas of war In a project, called Deep Ops, a pilot whale and two killer whales demonstrated their ability to recover objects from greater depths.
The recovery device the whales attached to the target object, a dummy torpedo containing an acoustic beacon, incorporated a hydrazine gas generator which was activated upon attachment of the device to the torpedo.
The generated gas filled a large lift bag which raised the torpedo to the surface.
The picture shows an orca named "Ahad" enlisted in the navy working off the coast of Hawaii.
Ahad was one of two orcas working in the navy in Hawaii retrieving decoy torpedos on the ocean floor.
The other orca named Ishmel swam off when they were brought out to the open ocean and he never returned.
Ahad was captured in 1968 in October off the coast of Washington. He was a member of either J or L pod.
He died in 1974 after a short life of only 5 1/2 years in captivity.
