Obsolescence watch

Stock numbers the government still buys whose supply base is thinning. Each one carries the reasons in plain words: the government's own terminal codes, approved sources whose SAM registration has expired, a single source, a registration about to lapse, years of solicitations without an award. A source we cannot verify in SAM is shown as unverified, never counted as gone. Rebuilt nightly; this list is from 2026-09-28.
