Soldiers with the U.S. Army 7th Dive Division, 65th

Soldiers with the U.S. Army 7th Dive Division, 65th Engineer Battalion, 130th Engineer Brigade, prepare for their final dive of the day while executing underwater condition surveys of the ramps behind Hangars 101, 102, 103 and 104, Jan. 26, 2016, aboard Marine Corps Base Hawaii. The 7th Dive Division was working alongside the U.S. Army Corps of Engineers in order to determine the ability of each ramp to support possible landing craft use. While they could possibly serve useful in the future, the ramps are currently part of the Kaneohe Naval Air Station National Historic Landmark, having supported the PBY Catalina patrol fleet bombed during the attack on Dec. 7, 1941.
