What it is
JOSCAR is a shared pre-qualification register for buyer organisations in the Defence, Aerospace & Security sector. Suppliers complete a shared "JOSCAR questionnaire" that member buyers can use, rather than each buyer running a separate questionnaire of its own. The page reviewed does not set out the questionnaire's specific data fields in detail.
Who owns it
JOSCAR is operated by Hellios Information Limited (page footer: "© 2026 Hellios Information Limited. All Rights Reserved.").
Who asks for it
Voluntary. No source opened for this record states that any buyer requires JOSCAR registration of its suppliers. The register is a shared pre-qualification tool used by the listed buyer community; a supplier's participation is not shown to be mandated by any of them.
The site lists more than 30 buyer organisations under its Defence, Aerospace & Security sector, including BAE Systems, Boeing, General Dynamics, Leonardo, Lockheed Martin, MBDA, the Ministry of Defence, Northrop Grumman, QinetiQ, Raytheon UK, Rolls-Royce Submarines and Thales. These are listed as members of the JOSCAR buyer community; the page carries no statement that any of them makes JOSCAR registration a mandatory condition for its own suppliers.
