Submerging
On 22 Feb, the USS Tennessee, a Naval Ohio-class ballistic missile submarine, underwent demonstration and , shakedown operations (DASO) and successfully fired an D-5 Trident test missile off the coast of Cape Canaveral, Fla. Prior to sub submerging, Airmen of the 920th Rescue Wing, at nearby Patrick Air Force Base, cleared the launch path beneath the missile of mariners to allow a safe test. (U.S. Air Force photo/Capt.
