Question

Who belongs to AUKUS, and could other countries join?

Short answer

Australia, Britain, and the United States are members; because AUKUS covers more than submarines, another Five Eyes partner may eventually seek involvement.

Notes

Australia, the United Kingdom, and the United States are the current members. Nuclear submarines are the most visible project, but AUKUS also covers missiles and a wider set of advanced defense technologies. That broader scope gives other states reasons to seek partial or full participation even if they do not need nuclear-powered boats. Future involvement by at least one additional Five Eyes country is plausible, though it remains speculation rather than a current decision.
