From yesterday’s DOD Contracts, emphasis mine.
Austal USA, Mobile, Alabama, is awarded an $867,666,667 fixed-priced incentive (firm-target), undefinitized contract modification to a previously awarded contract (N00024-19-C-2227) for the detail, design, and construction of three expeditionary medical ships, an Expeditionary Fast Transport variant. Work will be performed in Mobile, Alabama (87%); Chesapeake, Virginia (2%); Newark, Delaware (2%); Mandeville, Louisiana (2%); Spring, Texas (1%); various locations within the U.S., each accounting for less than one percent (5%); and various locations outside the U.S., each accounting for less than one percent (1%). Work is expected to complete by May 2030. Fiscal 2023 shipbuilding and conversion (Navy) funds in the amount of $149,833,000; and fiscal 2022 shipbuilding and conversion (Navy) funds in the amount of $63,667,000 will be obligated at time of award and will not expire at the end of the current fiscal year. Naval Sea Systems Command, Washington, D.C., is the contracting activity.
The EPFs are speedy (43-knot) little (1500 ton, 337ft o.a.) trimarans made by Austal and manned by the civilian mariners of the MSC to carry a reinforced company-sized unit of ground-pounders or cargo intra-theatre.
The Navy has been brainstorming using an EPF equipped with an expeditionary medical unit (EMU) inside the mission bay that, while falling short of a full-size hospital ship, would allow an EPF/EMU to serve as a quick transit platform for rapid medical response. This could be helpful in special operations and in sending a smaller package overseas for humanitarian support than an LHD or USNS Mercy/Comfort.
The first of these, USNS Apalachicola (EPF 13), was accepted earlier this year and the future USNS Cody (EPF 14) is pending delivery.

The future USNS Point Loma (EPF-15) and the as-yet-unnamed EPF-16 are also under construction by Austal. Each of these ships is being constructed to “Flight II” specifications that incorporate Role 2E medical capability and capabilities to support V-22 Osprey flight operations.
I’d imagine that the latest contract is for EPF 17, 18, and 19.
Update
Looks like they are going to be white-hulled mercy ships, with the first carrying the name USNS Bethesda (EMS 1).

Via Austal:
Austal Limited (Austal) (ASX: ASB) is pleased to announce Austal USA has received a US$867.6 million (A$1.28 billion) undefinitised contract award (UCA) for the final design and construction of three Expeditionary Medical Ships (EMS) from the United States Navy.
The EMS is based on Austal’s proven Expeditionary Fast Transport ship (EPF) platform and will be manufactured in Austal USA’s aluminium manufacturing line following completion of the last Expeditionary Fast Transport (EPF 16).
Austal Limited Chief Executive Officer Paddy Gregg said the contract enables the final detailed design for the Expeditionary Medical Ship to be completed and construction of three vessels to commence.
“The new Expeditionary Medical Ship further extends the capabilities of the proven Expeditionary Fast Transport (EPF) platform, designed and constructed by Austal, to enable more complex medical procedures and operations to be performed onboard, at sea and underway,” Mr Gregg said.
“These three new EMS will enhance the US Navy’s capability to provide effective medical and surgical support anywhere in the world, quickly, safely and efficiently.”
The Expeditionary Medical Ship (EMS), an Expeditionary Fast Transport (EPF) variant, is a cost-effective design providing a dedicated medical ship optimized to provide patient holding, stabilization, evacuation and transport in support of Distributed Maritime Operations (DMO). The EMS design features a shallow draft which enables greater reach and allows for direct access to austere ports. The flight deck will accommodate military aircraft, including the V-22 Osprey and CH-53K heavy lift cargo helicopter.
Austal USA has delivered 13 EPF’s, a predecessor to the EMS design, to the United States Navy. The company is preparing to deliver the first EPF Flight II, the future USNS Cody (EPF 14), which features enhanced Role 2E medical capability, and has two more Flight II vessels under construction.
