Things to watch
From the version posted Oct 22, 2026.
- Serious: Task order under SeaPort-NxG. The notice puts this buy under the SeaPort-NxG multiple-award contract, so a business without that contract likely can't bid.
- Worth checking: Work abroad in Japan, Guam and Diego Garcia. The scope includes direct fleet support overseas, and the notice says nothing on local offices, licenses, taxes or travel requirements.
- Worth checking: Large level of effort and submarine quality rules. The work totals 425,150 hours over five years and requires SUBSAFE compliance and CMMI Level 3 equivalent software processes, which a small firm must be able to show.
