In the Western Atlantic and the Caribbean Sea
The amphibious ships USS Wasp (LHD-1), USS Kearsarge (LHD-3) and USS Oak Hill (LSD-51), along with the Marines of the 26th MEU, are providing humanitarian relief efforts for Hurricanes Irma and Maria.
Hospital ship USNS Comfort (T-AH 20) arrived off Puerto Rico on Oct. 3.
“Comfort’s primary mission is to provide an afloat, mobile, acute surgical medical facility to the U.S. military that is flexible, capable, and uniquely adaptable to support expeditionary warfare. Comfort’s secondary mission is to provide full hospital services to support U.S. disaster relief and humanitarian operations worldwide,” according to the Pentagon.
Amphibious assault ship Wasp joined the Kearsarge ARG in Puerto Rico last week with additional helicopters to assist with Hurricane Maria disaster relief efforts there.
Wasp departed for Puerto Rico with three MH-60S multi-mission helicopters and two MH-53 heavy-lift helicopters, but as the amphibious assault ship joined the ARG, the ship was augmented with four MH-53 and six MH-60 helos.
