Legend:

Laid down means that the ship's construction was officially started by laying down the keel (often just a single steel beam but could also mean the first of many pre-fabricated sections).

Launched means that the ship was launched from its shipyard, it then began its fitting out period (installation of smaller systems, weapons etc.) - in many yards the ships were launched very complete and needed little work afterwards.

Commissioned is when the navy takes the ship officially over and gives command of it to its new captain.

Upon firing Utmost went to 80 feet. One of the torpedoes had a gyro failure and appeared to be cruising around in an erratic and alarming matter. After 10 minutes HE from the torpedo became fainter and finally disappeared. At the time this was believed to have been the Italian Florida II (3100 GRT, built 1905) but she was at Sfax at the time.

At 1920 hrs that evening, while the formation was transiting Kasos Channel heading north, there was an attack by Italian S.84 level bombers belonging to the 205? Squadriglia, 41? Gruppo Bombardamento Terrestre, led by pilot Lt. Giovanni Ghinazzi. One of the bombs near-missed Imperial's stern, detonating in the vicinity of her propellers, with no immediately apparent consequences. Keeping station, Imperial arrived at Iraklion around 2030 hrs, embarked 300 troops and sailed for Alexandria at 0320 hrs, 29 May. Shortly after 0345 hrs, while working up speed and already making 29 kn, the rudder, evidently damaged by the earlier near-miss, jammed, and the out-of-control destroyer cut across the bow of Orion, barely missing a catastrophic collision. After determining the impossibility of carrying out repairs, and unwilling to delay the retreat of the entire Squadron, Radm Rawlings ordered Hotspur (Lcdr. C. P. F.

(All times are zone -8) 0150 hours - Sighted a ship bearing 338°, distance about 8 nautical miles. Closed to investigate. 0224 hours - Dived. The vessel looked like a destroyer lying to. Range was now 3 nautical miles. Continued approach submerged. 0240 hours - Fired two torpedoes from 1600 yards. A torpedo explosion was heard 1m 25s after firing the first torpedo. Observed a narrow column of water one quarter lenght from the bow. Continued towards the target and at a range of 600 yards thought the target was a tanker of about 3500 tons. Thebow was slightly down but the target did not seem to be sinking. Turned away to bring the stern tubes to bear. 0253 hours - Fired one stern torpedo.

Linton, DSC, RN) torpedoed and sank the Italian destroyer Emanuelle Pessagno (1917 tons, built 1930) and the Italian merchant Capo Arma (3172 GRT, built 1905) about 70 nautical miles north-west of Bengasi, Libya in position 33°15'N, 19°25'E. (All times are zone -3) 28 May 1942 2310 hours - In position 33°51'N, 18°54'E sighted a Southbound convoy of two merchant ships (6000 and 5000 tons each) escorted by two destroyers (one Spica class torpedo boat, the other looked bigger) bearing 325°. Speed was thought to be 12 knots. Due to the mist is was very difficult to estimate the convoys course and range. Cdr. Linton decided to get ahead of the convoy. 2345 hours - Turbulent was now on the convoys beam and that the convoys course was 160°. Turbulent went ahead and soon afterwards lost touch. 29 May 1942 0001 hours - Altered course towards and increased speed to find them. 0020 hours - The convoy was sighted apparently steering a course of about 200°. Started to get ahead. 0150 hours - The convoy changed course to 160° and later to 140°. 0230 hours - As there seemed no prospect in any change in the weather and that an attack at dawn (what Cdr. Linton initially intended to do) might be spotted by aircraft it was decided to make a submerged attack by moonlight. 0337 hours - Dived 5 miles ahead of the convoy and 3000 yards off track. 0401 hours - Sighted the convoy a little closer than expected. The escorting destroyer on this side of the convoy could not be seen or heard. 0405 hours - Sighted the destroyer, it was much closer than was anticipated. Turbulent was right ahead. 0407 hours - The destroyer was seen to be on a steady bearing. 0409 hours - Fired four torpedoes at one of the merchant vessels. The destroyer was now very near. Turbulent went deep upon firing. 1min. 13secs after firing the first torpedo an explosion was heard. Shortly afterwards one of the torpedoes passed over the conning tower. Two further explosions were heard 2min. 28secs. and 3min. 10secs. after firing the first torpedo. The torpedo that ran overhead had a gyro failure and with a great deal of luck had hit the destroyer that was so near to Turbulent. 0610 hours - Came to periscope depth and found one destroyer about 3 nautical miles away and moving slowly around the position of the attack. Nothing else was in sight. The other merchant ship in this convoy was the Italian merchant Anna Maria Gualdi (3289 GRT, built 1908). The other destroyer was the Antonio Pigafetta, she was off the Navigatori-class and a sister ship of the Emanuelle Pessagno. This class of destroyers were the largest Italian destroyers in service.
