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.

The convoy was a mess now. It is thought one of the targets had sunk as she had been observed with a 30 degree down angle with her stern in the air and she was not shighted afterwards. One ship was seen with a heavy list and another one lay low in the water. Both were smoking furiously. 0127 hours - Commenced second attack. Picked out the largest ship which had not been the target of the first attack. 0132 hours - One of the escorts came up from astern and opened fire from our port quarter. Went ahead emergency and changed course to put him astern (this was CH-22). Broke off the attack. 0135 hours - The escort was now closing the range to 2400 yards by radar. The merchant ship we wanted to attack now also opened fire and one shell whistled of the bridge. Dived to 450 feet and rigged for depth charges. 0140 hours - Received three small depth charges but they were not very close. The escort never gained contact. Surfaced. Commenced battery charge and set course to overtake the convoy.
