The precise date as to when Smith entered the Royal Navy is unknown, but his first notable appointment in the Service was to the position of junior lieutenant aboard the
Royal Oak on 6 February 1728, at the appointment of his commanding officer
Sir Charles Wager. In June of the same year he was moved to the 44-gun
Gosport under the command of Captain Duncombe Drake. While a lieutenant aboard the
Gosport, Smith attracted great controversy in an incident involving the French corvette
Gironde on 23 November 1728. At the time of the incident the
Gosport was harboured in
Plymouth Sound and Smith was acting-commanding officer due to all of his superiors being ashore. While in command, a French corvette that had entered the Sound for shelter passed the
Gosport while departing, and Smith signaled for the French captain ‘to haul in his pennant in respect to the king of Great Britain's colours’. On 5 May 1730, Smith was promoted to the rank of captain and given the command of the 24-gun
Success. Two years after this Smith was given command of the
Dursley Galley, a 20-gun fast frigate stationed in the
Mediterranean, mainly tasked with patrolling against
Barbary Pirates. Remaining mainly in the Mediterranean, Smith remained in this position for a decade. ==Tenures as Governor of Newfoundland==
