Performance Enhanced Real-time Ground Environment (PEREGRINE) Sentry

• Attachments increased from 1 to 3 (2 added, none removed). The two new files have no filenames or resource IDs in the change record, so their contents cannot be identified from this data.
• Why it matters: The added files are likely amendments, instructions, templates, or technical appendices, and applicants should download and review both before finalizing a submission. Because the filenames are missing, check the solicitation page on SAM.gov directly to confirm what each new document contains and whether it changes requirements, forms, or deadlines.

The close date moved from October 23, 2026 to October 30, 2026 (both at 21:00 UTC), a one-week extension. Applicants now have seven additional days to submit, which gives more time to finalize proposals, budgets, and required documents. Teams planning around the earlier deadline should update internal timelines, but the extension does not otherwise alter eligibility or submission requirements.
