Upper belt, 15.0 cm
Torpedo bulkhead, 2.0 cm
Armor deck, average 14.0 cm
Conning tower, 23.0 cm
Battery armor:
Main, 25.0 cm / secondary,
15.0 cm
QF, 13.0 cm / light guns, 2.5 cm shields
Maximum speed for 6282 indicated kw = 16.00 knots
Approximate cruising radius, 3500 nm / 10 knots
Typical complement: 601-781
Estimated cost, $4.631 million (£1.158 million)
Remarks:
Relative extent of belt armor, 90 percent of 'typical' coverage.
Main belt does not fully protect magazines and
engineering spaces.
Ship has slow, easy roll; a good, steady gun platform.
Excellent seaboat; comfortable and able to fight her guns
in the
heaviest weather.
Main deck secondary guns subject to being washed down
in a seaway.
