French Audaciaux class destroyer, laid down 1921
Length, 100.0 m x Beam, 8.8 m x Depth,
3.6 m
1366 tonnes normal displacement (1231 tonnes standard)
Main battery: 3 x 12.0-cm (3 x 1; 1 superfiring)
AA battery: 4 x 4.0-cm
Light battery: 4 x 1.3-cm
Weight of broadside: 75 kg
8 TT, 53.0 cm in two quadruple
mounts
50 tons depth charges
Hull unarmored
Maximum speed for 26049 shaft kw = 33.00 knots
Approximate
cruising radius, 5100 nm / 12 knots
Typical complement: 112-146
Estimated cost, $1.667 million (£417,000)
Remarks:
Caution: Hull structure is subject to strain in open-sea
conditions.
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.
Cramped ship; poor crew accommodation, limited working space.
