Armor deck, average 6.0 cm
Conning tower,
20.0 cm
Battery armor:
Main, 20.0 cm / secondary,
16.5 cm
QF, 6.0 cm
Maximum speed for 23916 shaft kw = 23.00 knots
Approximate cruising radius, 6000 nm / 12 knots
Typical complement: 646-839
Estimated cost, $4.443 million (£1.111 million)
Remarks:
Relative extent of belt armor, 130 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.
