Request for Solution:

Modular Open Systems Approach (MOSA) for Department of War Consortium Manager and Marketplace

13 May 2026

1. Purpose

U.S. Army Contracting Command – Orlando (ACC-Orlando) is issuing this Request for Solution (RFS) on behalf of the Office of the Under Secretary of War.). The purpose is to identify, review, and select a Consortium Management Firm (CMF) who will create and manage a Modular Open Systems Approach (MOSA) Consortium with a strong and diverse membership, as well as create and maintain a MOSA digital marketplace platform for hosting and discovering certified MOSA solutions.

The Department of War (DoW) community is mandated to ensure programs incorporate a MOSA as part of the defense acquisition program life cycle. The purpose of this RFS is to assist in the achievement of this mandate. The MOSA Consortium embodies the Department’s commitment to breaking down barriers, fostering competition, and to ensure enduring technological superiority. As necessary and appropriate to accomplish this goal the Government may award using the authority of 10 U.S.C. § 4021: Research projects; transactions other than contracts and grants, U.S.C. § 4022: Authority of the Department of Defense to carry out certain prototype projects, and U.S.C. § 4023: Procurement for experimental purposes.

The Government will evaluate prospective solutions with the intent to competitively award an Other Transaction Agreement (OTA) for consortium management and a digital MOSA marketplace through ACC-Orlando.

2. Summary and Background

MOSA is an acquisition and design approach consisting of technical and business architecture that supports using system interfaces compliant with widely supported and consensus-based standards, to the extent that standards are available and suitable. A MOSA system structure allows for severable components to be incrementally added, removed, or replaced throughout the life cycle to afford opportunities for enhanced efficiency, competition, and innovation.

MOSA integrates technical requirements with contracting mechanisms and legal considerations to support a more rapid evolution of technologies and capabilities throughout the product life cycle using architecture modularity, open systems standards, and appropriate business practices (10 U.S.C 4401). DoD MOSA is intended to allow the Department to achieve competitive and affordable acquisition and sustainment of a new or legacy system or component of hardware, software, or an integrated assembly of both.

Vision, Mission, Strategic Goals and Acquisition Imperatives

Vision: To transform defense acquisition into a modular, agile, and innovation-driven enterprise that delivers warfighting capabilities at the speed of relevance. The MOSA Consortium OTA embodies the Department’s commitment to breaking down barriers, fostering competition, and ensuring enduring technological superiority.

Mission: The MOSA Consortium OTA shall serve as the Department’s principal mechanism for accelerating acquisition transformation through modular open systems. By uniting government, industry, and academia under a collaborative consortium, the mission is to:

• Drive rapid prototyping, integration, and fielding of modular capabilities.
• Institutionalize MOSA as the default acquisition strategy across all domains.
