T-AO 205 Class

The T-AO 205 Class program is a Navy initiative under Program Element PE 0605327N, focused on the research, development, test, and evaluation (RDT&E) of the John Lewis Fleet Oiler Class. The primary objective of this program is to recapitalize the Navy's existing T-AO 187 Fleet Oiler Class, ensuring continued and enhanced support for the Combat Logistics Force (CLF). These oilers are essential for supplying fuel and dry cargo to Navy ships at sea, thereby sustaining fleet operations and enabling extended deployments.

The T-AO 205 Class Development budget line (Project 3375) specifically addresses the completion of test and evaluation (T&E) requirements. The program's goals include conducting Developmental Test & Evaluation (DT&E), Operational Test & Evaluation (OT&E), and Live Fire Test & Evaluation (LFT&E) to validate the performance, survivability, and operational suitability of the new fleet oiler class. In FY 2024 and FY 2025, efforts were concentrated on finalizing the Initial Operational Test and Evaluation (IOT&E) Report and coordinating activities among key stakeholders such as the Shipbuilder, Naval Sea Systems Command (NAVSEA), Military Sealift Command (MSC), Program Executive Office Ships (PEO SHIPS), Commander Operational Test and Evaluation Force (COMOPTEVFOR), Joint Interoperability Test Command (JITC), and the Office of the Secretary of Defense Director, Operational Test & Evaluation (OSD DOT&E).

During FY 2024, the program completed the Operational Test Readiness Review (OTRR) and initiated the Final Survivability Assessment Report (FSAR) as part of the LFT&E process. By FY 2025, the focus shifted to finalizing the IOT&E Report, marking the completion of major T&E milestones. These evaluations are critical for verifying that the T-AO 205 Class meets operational requirements and complies with statutory and regulatory standards, such as the Oil Pollution Act of 1990 (OPA-90) and International Marine Pollution Regulation (MARPOL).

Beyond RDT&E, the program is supported by related procurement funding lines, including those for T-AO 205 Class Fleet Oiler construction and the completion of prior year shipbuilding programs. These procurement efforts are justified by the need to modernize the Navy's logistics fleet, ensuring reliable fuel delivery and support capabilities for carrier strike groups and other deployed naval forces. The acquisition strategy began with the award of the first fleet oiler contract in FY16, emphasizing compliance with environmental and operational standards.

The Test and Evaluation activities under this program have been comprehensive, involving multiple contract methods and performing activities across various Navy and Department of Defense agencies. The DT&E, OT&E, and LFT&E phases were designed to assess the ship's performance under operational conditions, validate survivability against potential threats, and ensure interoperability with other fleet assets. These rigorous evaluations help mitigate risks and inform future procurement and operational decisions.

As of FY 2026, all major test and evaluation activities for the T-AO 205 Class have been completed, with no further RDT&E funding planned. The program's accomplishments include the successful execution of all required testing, coordination among a broad set of stakeholders, and the delivery of key evaluation reports. These outcomes support the Navy's broader objective of maintaining a capable and resilient logistics force, able to sustain global maritime operations.
