Which early jet-age naval aircraft still serve?

After the latest Skyhawk retirement, does anyone still operate a naval aircraft of comparable age?

Brazil still operates Skyhawks, and other examples survive in aggressor roles, but few aircraft designed in the early 1950s remain in front-line service.

The Skyhawk dates to the early 1950s, and Brazilian service is the leading surviving example. Some aircraft of similar vintage continue in specialist aggressor work instead of ordinary fleet operations. This distinction separates active naval service from contracted training roles.
