UPDATE 13 AUGUST 2025: 

This UPUDATE provides important information regarding the GeoSES. The information provided below is for your situational awareness.

Regarding Document Availability:

From the SAM.gov August 6th update, while we have received requests from various companies through SAM.gov, no new documents have been posted yet as we are still awaiting updated documents and security approval for release.

FYSA - The August 6th update on SAM.gov was actually the removal of the SDSV1.3 document from "public availability". This document was marked as CUI (Controlled Unclassified Information) and should not have been publicly published. The document was then re-added with restricted/controlled access, requiring individual requests via SAM.gov. However, you should already have the SDSV1.3 document from previous communications. It is the same document; so, there is no need to request it via SAM.gov.

For all other pending documents necessitating release from the Government, be advised that we are still working through the process of releasing the documents. Our Security Office has neither finalized their reviews nor provided the clearance for releasing the documents yet. This will include the .ppt Industry Day Slide Deck. We are also still working in providing answers to all Industry Questions, and those will be publicized as well.

Document Access Process Change:

For future release of additional (or pending) documents, there will be no need to use DoD Safe for document sharing. Please disregard my previous communication update concerning the use of DoD Safe. SAM.gov provides a built-in feature that allows us to share restricted documents directly with requesting companies through the system. Once documents are approved and posted, you can submit your access request through SAM.gov. I will update this in SAM.gov once the new documents are ready to be released.

Milestone Date Clarification:

Regarding the September 12th Government Scientific Review milestone date versus the September 22nd White Paper due date, please know that ALL milestone dates (including the scientific review date) will be updated once the new or pending documents are released. As of now, the White Papers are still due on September 22nd. However, if the documents pending release (mentioned above) is significantly delayed, we may also extend the white paper due date accordingly. Therefore, please disregard all other previously provided milestones (except the White Paper Due Date of 22 Sep for now); and within the "GeoSES_SourcesSoughtNotice_Rev_2025.06.17" attachment.

Next Steps:

Although not necessarily guaranteed, I expect to have a clearer timeline on documents release by the end of next week (8/22) and will communicate any updates to milestone dates at that time if available.

Reminder:

A Top-Secret Facility Clearance (TS/FCL) Capability is still required. Companies not possessing the required FCL and/or having Active or Inactive Exclusions in SAM.gov at the time of documents release, will not be provided access to the documents.
