USNS Bethesda

Beginning with EPF-14, the ships will be designated as EPF Flight II, with increased health services capabilities while still maintaining most of the original mission of the ship.[2] The Flight II variant is designed to bring enhanced medical capabilities at the request of Combatant Commanders, and allows patients to recover onboard rather than in a higher-level facility. They can respond faster, and to more places than the Navy's larger, slower and unarmed hospital ships.[2][3] The EPF Flight II design includes upgrades to the medical facilities for resuscitation and surgery, enhanced support of V-22 flight operations, and enhanced launch and recovery of 11-meter rigid inflatable boats.[4]

In January 2023, the Navy announced that three Expeditionary Medical Ships (EMS) had been approved in the 2023 military budget. These will be T-EMS-1, T-EMS-2, and T-EMS-3. These are planned to be about 118m versus the earlier ships 103 metres (338 ft), and have a draft of 4.5 metres (15 ft) for operations in "austere ports". The EMS will have four operating rooms and 124 medical beds, separated into acute care, acute isolation, ICU, and ICU isolation spaces.[5] Two 11-meter rigid-hulled inflatable boats allow for the transfer of patients from other ships or water rescue; the flight deck has room for a single V-22, or an H-53 or H-60 helicopter. Bethesda is planned for delivery by December 2026.[6][1]
