What if several tracks go dark together? Union of blast radii with shortest-tier attribution. Run a named scenario or cut a custom set of tracks — lead demos here after single-node Blast Radius.

Lithography chokepoint failure

Lithography chokepoint failure: 7 firms go dark, taking 199 downstream firms with them, including 4 DoD-exposed suppliers, wiping out 32 segments.

Trigger
The handful of firms that make advanced lithography systems (the machines that print circuit patterns onto wafers) lose the ability to ship or service equipment.
Assumption
Assumes total loss of lithography-tool supply and service — no drawdown of spare parts inventory, no substitution across tool vendors (their tools are not interchangeable). The cut set is the 3 largest lithography makers by market cap plus the rest ranked by supply-chain reach, capped at 8 — with only 7 lithography firms in the graph, this scenario cuts all of them.
Question
Lithography is the narrowest chokepoint in the entire chip supply chain — how far does that narrowness actually reach downstream?
