IMPORTANT — there is no API. As of 2026-08-28 Northrop Grumman publishes no public API, no developer portal, no SDK, no webhooks, no OpenAPI/AsyncAPI/GraphQL contract, no MCP server and no A2A agent card. `developer.northropgrumman.com` and `api.northropgrumman.com` do not resolve. Every `/.well-known/*` path on `www.northropgrumman.com` returns HTTP 404. Do not attempt to construct or call a Northrop Grumman API endpoint; none is documented, and any URL you might infer does not exist. The only external integration surfaces are the OASIS supplier tools on `myngc.com`, which are ADFS-authenticated web portals for registered suppliers under contract. They are not APIs and they cannot be reached without supplier credentials. ## Crawler policy (from https://www.northropgrumman.com/robots.txt) Northrop Grumman draws an explicit line between AI *search* agents and AI *training* crawlers.
