Obsolescence watch: 5998 Electrical And Electronic Assemblies, Boards, Cards, And Associated Hardware
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 2026-09-29.
AAC X: semi-active, no procurement planned; one active source in SAM out of 2 approved (0 expired, 1 unverified); solicited in the last 12 months; last award Jun 2017; AMSC R on the latest solicitation: only approved sources may supply
