Decade view

P-1/R-1 workbook TOA basis, shown compact in $B/$M (the workbook records USD thousands); each figure cites its own President's Budget edition

5 fiscal years of this program as published (FY2022–FY2026): a line through the actuals (filled dots), with the enacted (hollow circles) and request (diamonds) markers each edition reported. Read it for direction, not for precision — this program's actuals line rises across the span. The grid below is the same data as text, one cited figure per cell.

The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.

Decade series values by fiscal year and President's Budget edition: one row per series (actuals, enacted, request), one column per fiscal year. Every figure opens its own citation.
Series	FY22	FY23	FY24	FY25	FY26
Actuals	$91.0M	$233.1M	$222.4M
Enacted	–	$241.2M	$259.0M	$268.1M
Request	–	–	$259.0M	$284.0M	$205.7M

blank = series not published for this year; – = absent from that edition.

Asked vs spent: the PB2024 book requested $259.0M for FY2024; the PB2026 book reported $222.4M as actual total obligation authority — $36.7M below the request. 222.358 − 259.044 = -36.686 USD millions — the compact figures above are rounded for reading.

Description

Description — Marine Corps Enterprise Network (MCEN)

Marine Corps Enterprise Network (MCEN) MCEN resources are foundational to Force Design and are a critical enabler for executing the Marine Corps Network Modernization Plan, which is the strategic vision of the Marine Corps' single global warfighting network. Investments sustain and increase operational readiness and reduce cyber vulnerabilities throughout the MCEN. Funding enables the Marine Corps to operate its network effectively to achieve Zero Trust, defend its network against cyber-attacks, and effectively mitigate cyber vulnerabilities. Additionally, a secure and modern network is foundational for enabling cloud migration, machine learning, and artificial intelligence initiatives that are a critical component of Force Design 2030. Enterprise IT Network Infrastructure provides the equipment to end users with network and voice connectivity to the core networks and services (e.g., Defense Information Systems Network - DISN), between installations, to buildings, access within buildings, and to remote locations. This includes physical and wireless connectivity of the Local Area Network (LAN) and Wide Area Network (WAN) as well as access to cloud and enterprise services. The program also provides the resources that enable and distribute voice networking through on-premise equipment. This line item includes funding specified for Defense Policy Review Initiative (DPRI) within the above details. Enterprise IT Security and Compliance provides resources related to IT security compliance and disaster recovery. This includes resources to set policy, establish processes and means, measure compliance, meet relevant legal/compliance requirements (e.g., Data Privacy, multi-factor authentication, etc.), and respond to security breaches and provide real-time operational security measures such as vulnerability scanning, management of firewalls, and intrusion prevention systems. In addition, this program provides resources to set disaster recovery policy, establishing processes and means, and performing disaster recovery testing (note: this does not include resources for disaster relief facility or servers for disaster relief facilities). Enterprise IT End User Devices and Services provides the resources to procure, operate, manage, refresh, sustain and administer end user devices. End user devices include enterprise business workplace devices (e.g., physical desktops, laptops, ruggedized laptops, or desktops, and thin or zero client machines), mobile devices managed by the Microsoft Intune container (e.g., tablets, ruggedized tablets, 2-in-1 devices, and the Intune container for Government furnished smartphones), and the Marine Corps Enterprise Desktop Standard (MCEDS) Image based on windows operating systems. Enterprise IT Compute and Storage provides the standardized enterprise service stacks to replace the obsolete hardware at the Marine Corps Enterprise Data and application sites, on/ off-premise and performing optimization assessments to reduce equipment that is no longer needed. The enterprise computing devices include physical and virtual servers. The program also provides storage capability in the form of online/offline storage to support archiving, backup, and recovery capabilities.

Justification

Justification — Marine Corps Enterprise Network (MCEN)

FY 2026 Base Appropriation Request: $205.710M. Enterprise IT Network Infrastructure: $105.376M in FY 2026 provides for the refresh and modernization of Voice Systems, Network Transport, and Tactical Entry Point requirements for planned bases throughout Marine Corps Installations East (MCIEAST), Marine Corps Installations West (MCIWEST), Marine Corps Installations Pacific (MCIPAC), Marine Corps Installations National Capital Region (MCINCR), and Marine Forces Reserve (MARFORRES), along with supporting Guam and Okinawa IT installation efforts to support the standup of new locations. Funding includes support for modernization and convergence of Voice Systems (voice modernization and leverage an agnostic transport solution to minimize hardware/software equipment), Network Transport (refresh, upgrade switches, routers, controllers, optical transport and standardize the MCEN architecture by streamlining transport communications), Tactical Entry Point (TEP) (an enabling component of the Deployed MCEN concept, providing tactical users reach-back access), and Defense Policy Review with the procurement, installation, and accreditation of Information Technology (IT) systems. The decrease from FY 2025 to FY 2026 of $31.763M is due to a decrease in the quantity and scope of the DPRI projects to be outfitted with Command, Control, Communication, Computers, and Information Technology (C4IT) equipment and fielding wireless capabilities to a decreased number of locations in FY 2026. Enterprise IT Security and Compliance (IT S&C): $25.375M in FY 2026 provides for the MCEN Management and Security capabilities. The decrease from FY 2025 to FY 2026 of $19.633M is principally due to IT S&C beginning to sustain equipment procured in prior years, while continuing to field to additional sites in FY 2026. Fielding will continue under Monitoring and Detection and authorized acquisition objective (AAO) expansion for Commercial solutions for Classified (CSfC). This additional funding will ensure the integrity, protection and proper use of the enterprise technology systems and data. Security and Compliance modernization efforts will increase reliability, automation, and threat vulnerability responsiveness for autonomous network operation, monitoring, and defense capabilities, supporting operations and management decisions in a zero-trust environment. These capabilities and services meet modernization requirements for Force Design 2030 and compliance with policy. Funding includes support for Security Solutions (which supports a full range of applications that will provide security-oriented outputs and outcomes), Monitoring and Detection (supporting capabilities that enable monitoring and detection capabilities that run independently without active input or management), and Threat and Vulnerability (for tools that monitor, track, assess risks, and mitigate identified threats and vulnerabilities). Enterprise IT End User Devices and Services: $59.238M in FY 2026 reduces cyber vulnerabilities and increases operational readiness throughout the Fleet Marine Force (FMF) and supporting establishment using the MCEN Non-secure and Secure (MCEN-N and MCEN-S). Allowing for EUDs refresh cycle in accordance with DoD CIO and OMB M-16-02 Memos. These memos direct a refresh rate of every 4-5 years to alleviate aging equipment that remains on the network and to meet industry standard periodicity refresh standards. If these end user devices (EUDs) are not replaced and refreshed, the Marine Corps is assuming cybersecurity risk throughout the MCEN resulting in technology obsolescence requiring EUDs to be removed from the network, negatively impacting operational readiness and FD 2030 IOC. The decrease from FY 2025 to FY 2026 of $8.291M is due to, completion of the Windows 11 compliance device mandate, which is required in 2025. Enterprise IT Compute and Storage: $15.721M in FY 2026 provides for the refresh of standardized Enterprise Service Stacks (ESS) to replace the end-of-life hardware at the Marine Corps Enterprise Data and application sites and perform optimization assessments to reduce equipment that is no longer needed. Funds Compute (provides for modernization of the servers across the non-classified side of the MCEN), Storage (provides persistent data on remote, network attached storage devices in order to make applications more responsive and the data sets more manageable), and Data Center Components (provides for an enterprise on/off-premises application modernization of the host systems and applications). The decrease from FY 2025 to FY 2026 of $2.677M is due to the planned refresh cycle of compute and storage. The FY 2026 request was reduced by $0.823 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative."

Contractor concentration

No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
