About VAMOSC
The Naval Visibility and Management of Operating and Support Costs (VAMOSC) management information system collects and reports US Navy and Marine Corps historical operating and support (O&S) costs. VAMOSC provides the direct O&S costs of weapon systems, some linked indirect costs (e.g., ship depot overhead), and related non-cost information such as flying hour metrics, steaming hours, age of aircraft, etc. The VAMOSC Military Personnel databases contain personnel costs and attribute data.
Depending on the specific commodity type and system, these relational databases contain up to 30 years of data presented by fiscal year in hierarchical cost element structures. The current content of the VAMOSC databases is summarized below:

Year | |
1700+ U.S. Navy and | FY1984 - Present |
Military Sealift Command ships | FY1993 - Present |
95+ Shipboard Systems | FY1993 - Present |
205+ Aircraft Type/Model/Series (TMS) | FY1986 - Present |
1000s of Aircraft subsystems | FY1996 - Present |
35+ air and surface-launched missiles and torpedoes | FY1990 - Present |
Military personnel (Navy and USMC active duty and reservists) | FY2002 - Present |
Military Training cost of instruction and student counts | FY2010 - Present |
*In 2020, OSD CAPE assumed responsibility for the collection and processing of USMC ground equipment O&S costs to be made available in the Enterprise VAMOSC (EVAMOSC) system. https://evamosc.osd.mil/ |

Depending on the cost element, data for a particular commodity is available not only at the system level, but also at the subsystem and component levels. The O&S cost data are collected annually from over 130 different sources. The VAMOSC Team collects, verifies and validates, processes and publishes the data to the VAMOSC system.
Cost analysts use VAMOSC data to develop the O&S portion of life cycle cost (LCC) estimates for future weapon systems. VAMOSC data also supports the statutory requirement for Independent Cost Estimates as part of the recurring program Sustainment Reviews. VAMOSC contributes to the Navy's efforts to reduce the Total Ownership Cost (TOC) of legacy and future weapon systems. VAMOSC is being used to identify significant cost drivers that represent cost reduction opportunities. Additionally, VAMOSC supports special studies/analyses, cost research, and modeling and simulation. Recent VAMOSC improvements have increased the breadth (i.e., coverage of weapon systems and cost elements), depth (i.e., level of detail provided), and timeliness of VAMOSC reporting.

The Naval VAMOSC databases are currently available to US government personnel and government contractors by several means. Frequent users have direct access to the databases and retrieve data themselves. Those who have a one-time or infrequent requirement can request data directly from the VAMOSC program office.
History of the Naval VAMOSC Program
2023 - Infrastructure and CIVPERS universe retired.
2023 - Naval VAMOSC migrates from Pentagon data center to AWS GovCloud.
2023 - Naval VAMOSC data available in ADVANA/Jupiter environment. DON O&S Cost Tool (Qlik application) created in Jupiter.
2022 - Converted escalation indices from Joint Inflation Calculator (JIC) to inflation using GDPPI for then year (TY) to constant year (CY) calculations.
