The Navy's proposed FY2025 budget requests $7.7 million in research and development funding for the program. The Navy's FY2024 five-year (FY2024-FY2028) shipbuilding plan programmed the procurement of the first TAOL in FY2026 at a cost of $150.0 million, the second in FY2027 at a cost of $156.0 million, and the third in FY2028 at a cost of $159.0 million. Compared to the Navy's FY2024 five-year shipbuilding plan, the Navy's FY2025 five-year (FY2025-FY2029) shipbuilding plan defers the programmed start of TAOL procurement by one year and roughly triples the estimated procurement cost of each ship-the plan programs the procurement of the first TAOL in FY2027, the second in FY2028, and the third in FY2029, each at a cost of $453 million. Term nology The Navy's Combat Logistics Force (CLF) ships, also called underway replenishment (UNREP) ships, are logistics ships that resupply the Navy's combatant ships (e.g., aircraft carriers, surface combatants, and amphibious ships) at sea, so that the combatant ships can continue operating at sea without having to return to port. The Navy's current CLF ships include oilers (TAOs), dry cargo and ammunition ships (TAKEs), and fast combat support ships (TAOEs). In these designations, T means the ship is operated by the Military Sealift Command (MSC) with a mostly civilian crew, A means auxiliary ship, 0 means oiler, K means cargo, and E means ammunition (i.e., explosives). (TAO, TAKE, etc. are also typed as T-AO, T- AKE, etc.) These CLF ships are large auxiliary ships. In the designation TAOL (also typed as T-AOL), the L means light, meaning a smaller version of such a ship. TAOL thus means an oiler that is smaller than a full-sized oiler. New Fleet Architecture and Operational Concepts To more effectively counter the improving A2/AD capabilities (i.e., capabilities that aim to create a defended area around a country that in time of conflict would be a no-go zone for opposing military forces) of China in particular, the Navy wants to begin shifting to a new, more distributed fleet architecture (i.e., mix of ships) that is intended to support a new Navy and Marine Corps operational concept (i.e., a general approach for using forces) called Distributed Maritime Operations (DMO), and an associated new Marine Corps operational concept called Expeditionary Advanced Base Operations (EABO). DMO aims at avoiding a situation in which an adversary could defeat U.S. naval forces by concentrating its attacks on a relatively small number of large, high-value U.S. Navy ships. Under EABO, relatively small Marine Corps units armed with anti-ship cruise missiles and other weapons would hop on and off islands in the Western Pacific to conduct shoot-and-scoot operations against adversary ships. For more on DMO, EABO, and the Navy's more distributed fleet architecture, see CRS In Focus IF12599, Defense Primer: Navy Distributed Maritime Operations (DMO) Concept, by Ronald O'Rourke. Logstics Ships Currently Beng Procured The Navy is currently procuring new John Lewis (TAO- 205) class oilers, which are large CLF ships. TAO-205s have a currently estimated procurement cost of more than $800 million per ship. For more on the TAO-205 program, see CRS Report R43546, Navy John Lewis (TAO-205) Class Oiler Shipbuilding Program: Background and Issues for Congress, by Ronald O'Rourke. Basic Concept for Ship The TAOL program (referred to in some documents as the NGLS or Next-Generation Medium Logistics Ship program) was initiated in the Navy's FY2021 budget submission. The program envisages building a new class of CLF ships (or a family of CLF ship designs) that would be smaller and individually less expensive to procure than the Navy's current CLF ships. Figure 1 shows a sketch of a Navy notional TAOL design concept. The Navy states that the TAOL is planned to be a new class of ships to augment the traditional Combat Logistics Force (CLF) to enable refueling, rearming, and resupply of Naval assets- afloat and ashore-near contested environments via ship-to-ship operations and ship-to port operations in support of Distributed Maritime Operations (DMO), Littoral Operations in a Contested Environment (LOCE), and Expeditionary Advanced Base Operations (EABO). Augmenting the traditional CLF, NGLS will provide a flexible, responsive platform to move fuel, personnel, equipment, and supplies between ships, advanced bases, ports, and dispersed nodes of the seabase; sustaining afloat (Surface Action Group) and ashore (Expeditionary Advanced Base) requirements.
