HMS Safari was a third batch S-class submarine built for the Royal Navy during World War II.

On 12 September, Safari was reassigned to the 10th Submarine Flotilla in Malta, with which she conducted two patrols in the Adriatic Sea, sinking one ship and damaging several more.

During a patrol off Naples, she was mistakenly bombed by British aircraft but was not damaged; Safari went on to sink four boats, then carried out special operations, landing men in Sicily, then later in Sardinia.

After an attack by an Italian destroyer in which she was not damaged, Safari conducted two patrols during the Allied landings in North Africa, sinking four ships.

Safari returned to England on 8 September 1943, and conducted training operations with the 7th Submarine Flotilla, punctuated by a short patrol off Norway to guard against a potential sortie to Germany of the German battleship Tirpitz.

On 13 June, she sighted a convoy of two Italian light cruisers, escorted by three destroyers and attempted to attack, but they were out of torpedo range.

On 14 August, Safari returned to normal patrols, and she damaged the Italian sailing vessel Gioavannina M with gunfire two days later.

On 2 October, she damaged the Italian merchant Veglia with gunfire and a torpedo, forcing the ship to be beached and then declared a total loss.

Two days later, Safari missed the Italian merchantman Valentino Coda with four torpedoes, then surfaced to use her main gun; the attack had to be broken off when the enemy returned fire and a destroyer was sent to hunt the submarine.

The Italian torpedo boat T5, which was patrolling close by, subsequently depth charged Safari, but caused only minor damage.

Two days later, she attacked but missed the steamer Goffredo Mameli, which was in a convoy with two other ships escorted by the Italian torpedo boat T7.

Later the next day Safari sank the Italian magnetic minesweeper Rosina S with gunfire, then finished it with a torpedo when it stayed afloat.

On 23 December, Safari made a short stop at Malta to land prisoners of war, refuel, and replenish her ammunition supply.

While patrolling south of Sousa, Tunisia, on 27 December, Safari sank with gunfire the Italian vessel Eleonora Rosa which was carrying 100 long tons (100 t) of petrol.

On 30 January, the boat sank the Italian schooners Sant’Aniello and Gemma, sailing for Vibo Valentia, with gunfire off Cape Scalea, Italy.

On 2 February she sighted and attacked a convoy of two Italian merchant ships off Capri; Valsavoia was sunk with torpedoes and Salemi with gunfire.

[1] On 22 February, Safari departed Algeria, this time on a mission to land reconnaissance engineers on the beaches north of Sicily.

[1] Safari departed Algiers on 27 March, with orders to patrol south of Sardinia, Italy, and, on 3 April, sank the Italian vessels Nasello and S. Francisco di Paola A with gunfire off the Gulf of Orosei.

After four days at sea, the boat sank the Italian auxiliary ship Sogliola with gunfire off Asinara Island, then went on to sink the minesweeper Onda with torpedoes in the same area.

On 8 May, she sank the Italian merchant ship Liv, which had earlier been damaged in an air attack, in Porto Torres, Sardinia.

They were to conduct reconnaissance and attempt to capture an enemy soldier for interrogation; however, the landing party came under fire on the shore and returned to the submarine with one missing.

[1] On 30 June 1943, the boat shifted to Bizerte, arriving the next day, then left port on 4 July to conduct her thirteenth war patrol, with orders to act as a directional radio beacon during the Allied invasion of Sicily.

Shortly before leaving port, Safari was accidentally rammed by a French tug, but sustained only minor damage which was repaired by her crew.

On 9 June, Safari executed her special mission off Licata, making radio contact with the American destroyer USS Bristol.

The next day, the boat sighted the Italian armed vessel Silvia Onorato, which was transporting 180 tons of cement; she fired two torpedoes at the ship, which erupted in explosions and quickly went to the bottom.

Safari then underwent a refit at Troon, then, after a stop at Holy Loch, departed for Rothesay, joining the 7th Submarine Flotilla.
