The open date moved from September 16, 2026 to October 2, 2026, a delay of 16 days (about two weeks and two days).

Why it matters: The open date is when applications can first be submitted, so the opportunity now starts later. No close date change was reported. If the deadline stays as it was, the submission window is 16 days shorter. If the deadline was extended in step, the window is unchanged. Applicants should check the listing for the current close date.

What to do:

• Treat October 2 as the earliest submission date, and don't plan on filing in mid-September.
• The delay gives more time to prepare the narrative, budget, partnerships, and registrations (SAM.gov, Grants.gov) before the portal opens.
• Confirm the close date. If it is unchanged, build a schedule that allows for the shorter window and has the package ready to submit as soon as the opportunity opens.

The close date moved from September 28, 2026 to October 16, 2026, a 18-day extension. Applicants now have more time to prepare and submit.

Why it matters:

• September 28, 2026 is a Monday and October 16, 2026 is a Friday, so the new deadline falls at the end of a work week. Confirm the exact submission cutoff time in the solicitation, since only the date changed in the data.
• The extra 2.5 weeks gives teams room to firm up partnerships, refine budgets, gather letters of support, and complete required registrations (SAM.gov, Grants.gov) that can take time to process.
• Applicants who were already on track for the original date can use the time to strengthen the technical narrative rather than rush. Those who had considered skipping this round may now be able to compete.
• Expect the pool of submissions to possibly grow, which may increase competition.

Action: Update internal calendars and proposal schedules to the new October 16 date. Check whether any related deadlines (questions, letters of intent, or pre-application steps) also shifted, as those were not part of this change.

No Substantive Changes Detected

The updated document appears to be identical to the previous version through the "APPLICABLE DOCUMENTS" section where the text cuts off in both versions.

Minor editorial changes only: The filename changed from "SOW_draft_20260908.docx" to "I_H_2__SOW_draft_20260908.docx" (appears to be an internal versioning prefix), but the actual SOW content remains unchanged.

No modifications to requirements, objectives, restrictions, technical scope, authorized users, sponsors, funding types, or supported systems are evident in this comparison.

Status changed from status: open to status: closed.

The opportunity description was significantly expanded from a brief notice to a comprehensive Statement of Work detailing specific technical services, authorized departments, sponsors, funding types, and scope for towed, hull, and sensor systems engineering support.
