Sailors and Marines assigned to the forward-deployed amphibious assault ship USS Essex move pallets as an MH-60S Sea Hawk helicopter drops off supplies during an underway replenishment with the Military Sealift Command fleet replenishment oiler USNS San Jose. Essex is the lead ship of the only forward-deployed U.S. Expeditionary Strike Group and serves as the flagship for CTF 76, the Navy's only forward-deployed amphibious force commander.
