Offshore and Aviation Fleet Mix Study Published

The Coast Guard has made public the Executive Summary of its Offshore and Aviation Fleet Mix Study. “FierceHomelandSecurity” has published a short summary of the content.

They also provided a direct link to the “Executive Summary” (a 24 page pdf). It is heavy with acronyms, and there is no list of acronyms attached to the Executive Summary, although there is probably one in the full study. I’ve attached a list of those I found, at the end of the post for those who might want a little help going through the summary.

“This initial phase of the FMA (Fleet Mix Analysis-ed.) is intended to address offshore surface and aviation capabilities. Follow-on FMA phases will assess capabilities needed for coastal and inland missions as well as emerging missions, such as Arctic operations and those of the Deployable Operations Group (DOG).

“ES.5.1  SCOPE:

“The FMA explored the projected Fleet mix requirements to meet the CG’s 11 statutory missions in FY2025. Mission requirements were based on nine Mission Performance Plans (MPPs) and an assessment of critical activities, such as training and support, which consume asset mission availability.

“The FMA included all CG aviation (fixed- and rotary-wing), all white-hull cutters (FRC up to NSC), and all applicable C4ISR systems.

“The FMA focused on activities in the offshore and aviation operating environment. Offshore and aviation are defined in the FMA as being generally 50+ nautical miles offshore and/or requiring extended presence. The FMA also considered missions within 50 nautical miles that consume air asset availability.

“The FMA used the 2007 CG Fleet, as defined in the 2007 Modeled CONOPS (Concept of Operations-ed.) and the “Deepwater” POR (Program of Record-ed.) as Baselines for comparative performance and cost analysis.


“Preliminary Operational Requirements Document (P-ORD) thresholds were used for the OPC (Offshore Patrol Cutter-Chuck).

“The OPC and NSC will operate 230 days away from homeport (DAFHP). No specific crewing method is assumed (i.e., crew rotation concept [CRC]).

“The HC-144A will operate at 800 programmed flight hours (PFH) per year. (This is a reduction from previous assumption–Chuck)

“U.S. Navy out-of-hemisphere (OOH) (2.0 OPC/NSC) and Joint Interagency Task Force South (JIATF-S) (7.0 OPC/NSC) support was consistent with the FY2010 demand.

“Additional acquisition/next generation platforms have the same capabilities and cost as the FMA Baseline Fleet mix cutters and aircraft (e.g., the next-generation short range recovery (SRR) helicopter is an MH-65C).


“The High Latitude regions of the ice shelf and Deployable Operations Group (DOG) mission requirements were not considered.

“No specific MDA performance measures have been established to model.

“87-ft coastal patrol boat (CPB), 225-ft seagoing buoy tender (WLB), Department of Defense (DoD)/Department of Homeland Security (DHS), and foreign asset contributions were considered, but force level requirements for 87-ft CPB, 225-ft WLB, DoD/DHS and foreign assets were not assessed.

“Additional shore facilities (e.g., schools, berthing, simulators/training aids, etc.) beyond those directly associated with platforms (e.g., piers, hangars, etc.) are not included in costs.

“”The need for non-operational/shore billet increases commensurate with the projected increases in operational manning was not assessed and is not included in costs.

“All cost estimates are rough order of magnitude (ROM) and are not budget quality.

“Additional specific assumptions utilized for modeling, simulation, and costing are included in their respective chapters of the final report.

“ES.3  Methodology:

“The Fleet Capacity Analysis (FCA) combined information developed in the mission validation phase, the capability definition phase, and a Warfare Analysis Laboratory Exercise (WALEX) to produce an objective Fleet mix and incremental Fleet mix alternatives. To develop the objective Fleet mix, the FMA used three independent teams with unique force projection tools or methodologies – the Database Enhanced Center for Naval Analysis (CNA) IDS Asset Assessment Tool (CIAAT) Model (DECMv2), the Mission Effectiveness Asset Needs Model (MEAN), and a qualitative analysis by a panel of CG SMEs – to develop a force structure that was aligned with MPP capability and capacity targets. Each team applied their methodology using a common set of asset characteristics and mission demands to develop a zero-based force mix (capable of meeting all mission requirements) projection. The results from these independent projections were considered as three “lines of position” (LOPs) and were consolidated to form a conceptual “fix.””
