Project Meridian

This open call is not a solicitation and is not related to an active or anticipated contract award. Responses do not constitute proposals and will not be used to select a contractor or make an award. 

Project Meridian will not develop acquisition requirements, specifications, statements of work, or source-selection materials.  Participation in this open call, including selection for follow-up engagement, confers no advantage in any current or future government acquisition. 

Submissions focused on near-term solutions, products, or capabilities will not be considered for Project Meridian. MITRE assumes no financial responsibility for any costs incurred in preparing or submitting a response or participating in follow-up activities.

MITRE will review all timely open call submissions received and assess them against the same objective criteria: alignment with Project Meridian’s goals and objectives, novelty, and relevance to the project’s future time horizon.

Based on this review, selected submitters may be invited to participate in follow-up activities to expand on their ideas, clarify key concepts, or provide supporting evidence. These activities may take the form of written email exchanges, virtual meetings, or in-person engagements.

During any follow-up, MITRE will focus on listening and gathering information and will not share nonpublic information. Selected participants will receive additional details and instructions.

Due to the anticipated volume of submissions, MITRE does not expect to provide individual feedback or evaluations to submitters.

MITRE will store submissions on a secure internal site with access restricted to the Project Meridian team. Submissions will be handled in accordance with the terms of this open call and used solely to support Project Meridian.

MITRE may use submitted information, in whole or in part, to inform its independent analysis and reports to the Department of War. Information may be incorporated into aggregate findings and shared with the Department of War and Project Meridian members, as appropriate.

Participation is voluntary. MITRE is under no obligation to respond to a submission, incorporate submitted information into its analysis, or engage with a submitter.

To ensure that Project Meridian remains an open, unclassified effort, submissions must meet the following requirements:

• Submissions must not contain classified information, Controlled Unclassified Information (CUI), export-controlled information, or information whose disclosure is restricted by law or contract.
• Submissions must not include trade secrets, proprietary information, or confidential information belonging to the submitter or any third party.
• All submitted information must be free of restrictive markings or expectations of confidentiality, and submitters must have the right to provide the information for the purposes described in this open call.
• Submissions must not contain marketing materials, product or service pitches, pricing information, requests for funding, or requests for endorsement.

Submitting information does not create any contractual, advisory, fiduciary, or other relationship with MITRE or the Department of War, nor does it establish any obligation on the part of either organization.

Submission Deadline: November 12, 2026 at 11:59pm EST

Responses received by the deadline will be reviewed and considered. Responses received after the deadline may be reviewed as time and resources permit, but only after all timely submissions have been considered.  Review of late submissions is not guaranteed.
