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.

Destroyer ORP Piorun: At 11.00 AM Capt. Vian (in HMS Cossack) received a radio report about the position of the Bismarck. He realized that the 4th Destroyer Flotilla was only 50 miles away and ordered to chase the enemy. Due to bad weather and high waves, the destroyers were able to maintain 27 knots speed (only two knots more than Bismarck), but continued the pursuit. Fortunately, British aircraft managed to hit the enemy with two torpedoes. One of them jammed the rudder and damaged the screws. The allied destroyers steamed in line formation, one about 25 cables from another. In darkness, Piorun lost contact with her British partners. At 2214hours lookouts spotted a large ship which identified herself as HMS Sheffield. At 2237 lookouts detected another large ship. The Polish commanding officer Cdr. Plawski was afraid of attacking the unidentified vessel, because it could be HMS Sheffield again. Piorun used an Aldis lamp to transmit a signal. The answer was 6" gunfire, The detected ship was the Bismarck!!! Cdr. Plawski ordered to open fire with the six 4.7" guns. During 59 minutes Piorun continued transmitting radio reports and traded fire with German battleship achieving several hits. Of course, 4.7" shells were able only to destroy some light AA guns, but not to penetrate heavy armour. The Polish destroyer was making lot of evasive manoeuvres, because Bismarck also used her 15" main armament. The British destroyers appeared on scene and conducted a torpedo attack against the German battleship. But all torpedoes missed the target. At 2336hours Piorun lost contact with the enemy.
