The names are British.
The filings are not.
Everyone can see the ramp — the backlogs, the funded programmes. This briefing reads two registers together — six current SEC annual filings and the live Companies House register — and shows who now owns the UK aerospace supply base, name by name: 73 UK subsidiary lines under six US-listed owners, every line checkable at a filing or a company number.

Four things two registers show together.
Meggitt, Weston Aerospace, Irvin, H+S Aviation, Vector Aerospace — names still spoken as independent British firms, declared as subsidiaries in six US owners' own annual filings. And the filings state their own boundary: significant subsidiaries only. The filed map understates the holdings.
Ultimate control of Weston Aerospace — a Farnborough sensor house — changed in March 2019. No entry anywhere in its four-company UK ownership chain records it; the chain ends at an active 2016 statement that there is no registrable controller. The register you check for control did not move when control moved.
Meggitt resolves upward through nine ownership hops — all active UK companies — to an Ohio corporation, entered on the acquisition's completion day. The public-interest conditions are on the record; eight months later, MEGGITT PLC became MEGGITT LIMITED.
The largest line in the live fortnight is £65.5m of commodity aircraft spares, signed. The drone lane opened from two separate buyers. And mid-record, one notice names the National Armaments Director Group where another, published the same day, still says DE&S — the buying machinery changing name inside the record.
Each finding in the briefing traces to a named public record — a notice ID, a filing, a register entry — so you can check any line yourself. The full read, with sources, is in the PDF.
What the public record doesn't settle.
What the public read cannot settle is your own chain — which of the names in your supplier list, your fleet plan, your data room or your borrower's book resolve, today, to which owner, at what register lag. That is a scoped, private read: your suppliers, your counterparties, graded to the same published standard, under NDA.
