All three cited sources are reachable and document the rated outcome for this specific promise. The core objective is achieved: the Coast Guard officially designated Juneau as homeport for its new medium icebreaker (Aug 2024), the USCGC Storis arrived in Juneau's Auke Bay Aug 7, 2025 and was commissioned in Juneau Aug 10, 2025 as its future home port. The CHAMPIONED leadership bar is satisfied — this is authorship/securing of provisions, not a mere vote or generic support: (a) Sullivan's office documents that he "secures a provision in the 2022 Coast Guard Authorization Act authorizing $150 million" and "secures $300 million in the One Big Beautiful Bill to homeport the Storis in Juneau"; (b) independent KTOO reporting singles him out — "Alaska's congressional delegation – particularly Sen. Dan Sullivan – has discussed plans to dock an icebreaker in the capital city for years" — the word "particularly" corroborating a leading role beyond the delegation; (c) Seapower (Navy League) shows him participating in the commissioning and championing the effort. Quotes are substantially accurate; the only defect is that one clause of the KTOO quote (the "August 2024 official homeporting announcement") is a factually-accurate paraphrase rather than verbatim (the article says "Last year, the Coast Guard made the official announcement after Congress passed a spending bill"), but the two load-bearing KTOO clauses are verbatim and the outcome does not rest on that clause. Confidence held at 0.82 rather than higher because the strongest explicit leadership language is from Sullivan's own office (self-published, though checkable and independently corroborated) and because the ship is temporarily berthed in Seattle while Juneau's shoreside facilities are built (permanent stationing later) — but the homeport is officially secured, the icebreaker is real and commissioned in Juneau, and the funding is enacted, so the promise is met.
