World of Warships Supertest: British Tier X Battleship St. Lawrence
4 min readHistorical background
Just like St. Vincent, St. Lawrence is based on the I3 design of battlecruisers. In terms of design studies, I3 preceded G3 and introduced the strange layout of having all turrets located forward of the ship around the superstructure and the engines at the rear. The purpose of this layout was to maximize firepower, as well as engine power, while still having a reasonably compact hull.
Thanks to this design, the estimated speed would have been 32.5 knots provided by an impressive 180 000 horsepower. The main battery consisted of nine 18-inch guns (457 mm) in three triple turrets, two superfiring at the front and one amidship facing aft.
Even with these innovations, the design was still considered too big, limiting the number of available drydocks. As such, it was abandoned in favor of the smaller G3 design.
If you want to learn more about the I3 design as well as the other battlecruisers designs from the Royal Navy, here is a video from Drachinifel covering them:
St. Lawrence is used as a testbed for an alternative design for the British battlecruisers. The main battery is very similar to Thunderer with fast reload, high accuracy, and thermonuclear HE shells but standard AP fuse timer. The firing range is also improved.
In exchange for the beefed-up main battery, Lawrence only gets a standard Repair Party and has a 32 mm deck. Her torpedoes also have a much shorter firing range and finally, she gets worse concealment.
Ship’s preview
For the classic reminder, this is a ship in testing, anything can change so don’t look at her like she would already be released.

Personal Opinion
I will keep it simple yet clear. St. Lawrence is literally Thunderer+1. She has the same guns but with nine instead of eight, a better reload, and a better sigma. She also has better citadel protection, better firing angles, is much faster and for any close quarter encounter, she has torpedoes.
As of right now, this ship looks particularly nuts.
