I wonder if the Liberty ships on lease to Britain and renamed with a "Sam" prefix were categorized by completion time.
Not a "Sam" ship, but a Liberty for US service, the 'Robert E Peary' was launched in 4 days, 15 hours and 29 minutes from keel laying. She went to sea on war duty 14 days after construction was started.

To add to what Bruce wrote I pulled this off the web acouple of years ago.
In the early days of the program it was evident that the sheer quantity of ships was essential and the solution was "ship built by mile and chopped off by the yard". New shipyards were created by a syndicate formed by Todd Shipyards Inc., and the Henry J Kaiser group.
Once the production lines got under way, the time taken to build a Liberty at Fairfield dropped to as little as 28 days. On the average, it took 592,000 man-hours to build a Liberty Ship. The construction of one Liberty ship required 3,425 tons of hull steel, 2,725 tons of plate, and 700 tons of shapes, which included 50,000 castings.
The Kaiser shipyard in Oakland, California, built the S.S. ROBERT E PEARY, from keel laying to launching, in 4 days 15 hours and 30 minutes. The PEARY was then outfitted, painted, taken on sea trials, the crew was trained and the vessel fully loaded with 10,000 tons of cargo. The PEARY sailed 7 days after the keel was laid.
It was felt that if the ship could make more than one trip it would be cost effective. Luckily, the Battle of the Atlantic swung to the Allied side, and only 196 Liberties were lost in combat. Approximately half the surviving fleet was sold at the wars end, and some of those were still in service in the early 1970's some 25 years later.

Rumour has it that they built them so fast that an empty Coke bottle was found inside a boiler some years later during maintenence. Didn't have time to remove it.
