The first proposal for "Alsace", No. 1, was essentially a slightly enlarged version of Project C. The ship had a longer hull, which required a increase in horsepower while incurring a loss of one knot in top speed. No. 2 was a scaled up version of No. 1, with the 380 mm guns replaced with 406 mm guns. The even larger hull necessitated a further increase in horsepower by to maintain the same speed. The No. 3 type was enlarged further to accommodate three quadruple 380 mm turrets, though it managed to increase speed by a knot. All of the designs would have carried a light anti-aircraft battery of and guns, but the numbers and arrangements of those guns had not been finalized before the program came to an end.
