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.

Submarine HMS P 32: HMS P 32 (Lt. D.A.B. Abdy, RN) is lost by an explosion (either internal or a mine) off Tripoli, Libya while attacking an enemy convoy. (All times are zone -2) Around 1530 hours P 32 was at periscope depth when a convoy of four medium seized merchant ships in line ahead was sighted with an aircraft overhead. No escorts were seen. Started attack on the rear ship that was thought to be a tanker of about 6000 tons. Went to 50 feet and closed at speed. Around 1540 hours when P 32 was returning to periscope depth from 50 feet when at 34 feet an explosion occured and P 32 took a large angle bow down. She was out of control and hit the bottom at 200 feet where she remained. The submarine was flooded up from forward up to the control room. Chlorine gas was filling the submarine and it was decided to try to escape from the engine room escape hatch using D.S.E.A. apparatus. The Commanding Officer and two ratings went to the conning tower to try to escape from there. The commanding officer and one of the ratings, the coxwain, succesfully did so. The other rating drowned during the attempt. The two survivors were later picked up by an Italian MAS boat and taken to Tripoli. The ships P 32 had sighted were part of a convoy made up of the Italian merchants Nicolò Odero (6003 GRT, built 1925), Caffaro (6476 GRT, built 1924), Marin Sanudo (5958 GRT, built 1926), Giulia (5921 GRT, built 1926) and the Italian tanker Minatitland (7651 GRT, built 1941). Another Italian merchant vessel the Maddalena Odero (5545 GRT, built 1921) had already been torpedoed and damaged by aircraft and was no longer part of this convoy. Escort of this convoy had been the Italian destroyers Freccia, Euro and Dardo.
Battleship HMS Prince of Wales: HMS Prince of Wales (Capt. J.C. Leach, MVO, RN) arrived at Scapa Flow.
Sloop HMS Banff: HMS Banff (Lt.Cdr. P.S. Evans, RN) picks up 18 survivors from the Norwegian tanker Mirlo that was torpedoed and sunk on 11 August 1942 about 870 nautical miles west-south-west of Freetown in position 06°04'N, 26°50'W by German U-boat U-130.
Submarine HNoMS Uredd: HNoMS Uredd (Lt. Røren) shifted from Dundee to Rosyth where she was to participate in A/S exercises.
Submarine HNMS K XIV: HrMs K XIV (Lt. J.H. Geijs, RNN) departed Diego Saurez for East London, South Africa.
Submarine USS Wahoo: USS Wahoo (Lt.Cdr. M.G. Kennedy) arrived at Pearl Harbor.
Armed Merchant Cruiser HMS Cheshire: At 18.52 hours on 18 August 1942 German U-boat U-214 fired four torpedoes at the convoy SL-118 from between the columns and claimed the sinking of four ships totalling 20,000 grt. In fact, one torpedo damaged HMS Cheshire (A/Capt. H.G. Hopper, RN) another sank the Hatarana and two torpedoes sank the Balingkar.
Submarine HMS Safari: HMS P 211 (Cdr. B. Bryant, DSC, RN) torpedoed and sank the Italian merchant Perseo (5225 GRT, built 1921) near Cape Carbonara, 15 nautical miles south of Serpentara, Sardinia. On this day P 211 also attacked but missed the Italian submarine Bronzo with torpedoes. (All times are zone -2) 0843 hours - The Officer of the Watch reported a large tanker bearing 210°. Enemy course was 010°, range 13000 yards. Started attack. 0856 hours - While coming up to have another look sighted a German uboat crossing astern out of range. Had we not closed to attack the target we would have been in a perfect position to attack the uboat. The tanker was very large, not loaded, not zig-zagging and unescorted. 0914 hours - Fired 3 torpedoes from 750 yards. Two hits were obtained. The ship was abandoned and started to settle by the stern. Position was 8 nautical miles South-South-West of Cavoli Island (approximately 38°58'N, 09°30'E) 1145 hours - The tanker refused to sink. A salvage party had gone on board. In order to make sure she would sink decided to fire another torpedo. 1148 hours - Fired 1 torpedo from 800 yards. The result could not be observed as a seaplane circled overhead and P 211 had gone deep upon firing. Breaking up noises however followed immediately. 1200 hours - Returned to periscope depth. No sign of the tanker. Went deep to reload. The “German” U-boat sighted was actually the Italian submarine Granito who witnessed the attack from a distance. This was the first time that torpedoes equipped with the new CCR magnetic pistols were used in the Mediterranean. MAS 504 was sailed to rescue the survivors of Perseo and hunt the submarine. The whole was saved including one seriously and eight slightly wounded. ------------------------------------------ 2000 hours - Now sighted an Italian submarine in position 214°, Cavoli Island, 24 nautical miles (approximately 38°48'N, 09°20'E). Enemy course was 000°, range about 6 nautical miles. Ran in at maximum speed. 2031 hours - Fired 6 torpedoes from 3500 yards. Enemy speed was estimated at 12 knots. Depth control was lost and P 211 broached. This was due to a defect and not to bad handling. Also one of the torpedoes prematured. The Italians immediately changed course and no hits were obtained. In Bronzo (T.V. Cesare Buldrini), an explosion was heard on the hydrophone and estimated at a range of 4000 yards. This was the torpedo which exploded prematurely. A few minutes later the submarine was apparently shaken badly by two hits under the hull and Buldrini believed that she had collided with the enemy submarine but this was probably caused by torpedoes equipped with the DCR (Duplex Coll Rod) magnetic pistols which proved to be unreliable. The first four torpedoes used DCR pistols, the last two used the more reliable CCR (Compensated Coll Rod) pistols.
Submarine HMS Splendid: HMS P 228 (Lt. I.L.M. McGeogh, RN) departed Sheerness for Portsmouth. She made the passage in convoy CW 116.
Submarine HMS Upright: HMS Upright (Lt.Cdr. A.F. Collett, DSC, RN) carried out A/S exercises with HMS Inglefield (Cdr. A.G. West, RN) and HNoMS Eskdale (Lt.Cdr. S. Storheill).
Submarine HMS Unbroken: HMS P 42 (Lt. A.C.G. Mars, RN) ended her 5th war patrol (also 5th in the Mediterranean) at Malta.
Submarine HMS United: HMS P 44 (Lt. T.E. Barlow, RN) torpedoed and sank the Italian transport ship Rosolino Pilo (8326 GRT, built 1942) 50 nautical miles bearing 190 of Pantellaria. The Italian ship was already damaged in a previous attack by British aircraft. Rosolino Pilo had been escorted by the Italian destroyers Maestrale and Gioberti and was en-route from Trapani to Tripoli. She had a civilian crew of fifty, a naval crew of thirty-two Italians and thirty-nine as well as 110 German passengers. There were no casualties as they had evacuated long before P 44 with the exception of Captain Oreste Tomassi and four sailors who had remained on board and left just shortly before the submarine finished her off. (All times are zone -2) 17 August 1942 In the evening P 44 was ordered to investigate the scene of a successful RAF attack on a merchant vessel in position 295°, Lampion Island, 16 nautical miles. 2050 hours - Set course to comply with the orders. Several new positions were signalled later on. 2234 hours - Sighted a flare. Closed the scene as it had been signalled that the RA would drop flares over the damaged ship. 2239 hours - A second flare was fired. Sighted the target in the light of the flare. More flares were dropped at 2246, 2250, 2303 and 2307 hours. 2307 hours - The merchant vessel could now clearly be seen in the light of the last flare. Range was 6 nautical miles. Closed. No escort was seen and the merchant, of 7000 to 8000 tons, was stopped and down by the stern. She was in position 302°, Lampion Island, 29 nautical miles. 18 August 1942 0009 hours - Fired one torpedo from 1500 yards. The result was gratifying, if unexpected. The explosion of the torpedo was followed instantaneously by another of gigantic proportions as the whole merchant ship exploded. As the commanding officer left the bridge a violent hot blast reached P 44 and debris was already clattering on the casing and before it was possible to dive, a report of the motor room was received of water coming in fast. P 44 therefore remained on the surface as no escort seemed to be present and when the hailstorm of debris had descended, it was found that the bridge was partially wrecked by a 12 foot length of one-inch frame embedded in the starboard side. Jumping wire had parted and loop and main aerials broken. In addition, upper steering was wrecked. There was no sign of the merchant ship. The pressure hull aft was examined and a 6" gash was found which was then caulked with wood and cotton waste. A signal was then sent to Malta reporting the situation. 1309 hours - Received orders to return to Malta. Set course accordingly.
Submarine HMS Unshaken: HMS P 54 (Lt. C.E. Oxborrow, DSC, RN) arrived at Dundee.
Destroyer HMS Boreas: HMS Boreas (Lt.Cdr. E.L. Jones, DSC, RN) picks up 18 survivors from the Norwegian tanker Mirlo that was torpedoed and sunk on 11 August 1942 about 870 nautical miles west-southwest of Freetown in position 06°04'N, 26°50'W by German U-boat U-130.
