Wikipedia states Fel'dbaum was "professor of missile control systems" at a Soviet military academy, 1945–1964 — uncited on the article itself

Wikipedia's biography of A.A. Fel'dbaum states he was a professor in a missile-control-systems department at the institution now known as the Peter the Great Military Academy of the Strategic Missile Forces (claim-dzerzhinsky-artillery-academy-institutional-ancestor-peter-the-great-missile-academy), from 1945 to 1964. The phrase recorded here, "professor of missile control systems," reached the vault through a web-search summary; the article was not directly captured at the time (no source_sha), and a 2026-09-20 audit re-check of the live article rendered its wording as fuller — "professor of the department of missile control systems of the faculty of reactive armament," with "From 1945 to 1964, he lectured there" — so the quoted phrase is additionally [unverified-quote — needs direct read]. The article carries a page-wide "lacks inline citations" maintenance banner, and the professorship sentence has no inline citation attached. It is not corroborated by the one independent source this capture checked — Fel'dbaum's own home institute's biography page, which lists two of his books published through Soviet military-academy presses in this period (claim-feldbaum-books-published-through-dzerzhinsky-military-academies) but names no teaching post or title there.

[unverified-mechanism -- needs primary]. This is recorded as a lead, not a fact: per the vault's sourcing floor, a specific, surprising, load-bearing biographical claim needs Tier 1–2 sourcing, and an uncited Wikipedia sentence does not clear it. The claim is the most vivid piece of this capture's research — a literal teaching title in "missile control systems" — and also its weakest-sourced.
