Armor deck, average 5.0 cm
Conning tower, 20.0 cm
Battery armor:
Main, 18.0 cm / secondary,
10.0 cm
QF, 5.0 cm
Maximum speed for 15841 indicated kw = 21.50 knots
Approximate cruising radius, 7000 nm / 10 knots
Typical complement: 536-697
Estimated cost, $4.072 million (£1.018 million)
Remarks:
Relative extent of belt armor, 120 percent of 'typical' coverage.
Ship has slow, easy roll; a good, steady gun platform.
Good seaboat; rides out heavy weather easily.
Magazines and engineering spaces are cramped, with poor
watertight
subdivision.
Main deck secondary guns subject to being washed down
in a seaway.
