Federal contracts (USAspending, last 180 days)

No award action to a recipient named exactly "NORTHROP GRUMMAN CORP /DE/" in the last 180 days. Subsidiaries and differently-spelled recipients are not matched — search contracts.

Lobbying (Senate LDA, as client)

No LDA filing names "NORTHROP GRUMMAN CORP /DE/" as the client in the last two years. Filings under a subsidiary or trade-association name are not matched — search lobbying.

Sources and method

Insiders and their transactions come from SEC EDGAR Form 4 filings for this issuer. Contracts and lobbying are matched by exact normalized name (suffixes like Inc./Corp. ignored) to USAspending recipients and LDA clients — a conservative match that misses subsidiaries on purpose. See methodology and corrections.
