Preserved Swordfish still fly, while Wessex helicopters lingered in service

What is the oldest naval aircraft still flying or still in service?

Airworthy Swordfish survive in preservation, while some Wessex helicopters were likely among the oldest aircraft still in naval service.

The word 'service' matters here. Fairey Swordfish and other historic naval aircraft remain airworthy through preservation, but that is different from operational fleet use. Wessex helicopters surviving with some navies are offered as a likely contender for the oldest type still in service. Any longevity comparison must distinguish museum flight, reserve status, and genuine operational employment.
