The estimated horse-power is 8548 (not 5500 as stated on page 76) with natural draft, and 12,000 with forced draft, the estimated speed being 16 knots, the coal capacity 800 tons, and the coal endurance 1500 miles at full power and 3500 miles at 11 knots speed. The _Neptune_ and the _Hoche_, of the same general plans and dimensions, were launched in the spring of this year. As originally designed the _Hoche_ was expected to develop 16 knots and 7000 indicated horse-power, but by the application of forced draft the speed was increased to 17½ and the power to 12,000. The armament consists—not of the four 52-ton guns given in the table on page 76—but, as stated in the text, of two 13.4-inch guns (34 centimetre) mounted one in each of the midship turrets, of two 10.6-inch guns (27 centimetre) carried one in each of the waist turrets, and of eighteen 5.5-inch guns (14 centimetre) so disposed in broadside within the unarmored central superstructure which occupies the deck between the turrets that the forward and after pairs are given bow and stern fire respectively. The armor-belt is similar to that of the _Marceau_, but the protective deck is from 3.15 to 3.54 inches thick, and the heavy gun sites are protected by 15.75 inches of compound armor. The _Amiral Courbet_ (formerly the _Foudroyant_) carries four 10.6-inch, six 5.5-inch, and twelve rapid-fire guns. She developed 6016 horse-power with natural and 8088 with forced draft, the mean speed being 14.2 knots on a consumption of 2.35 pounds per power each hour. The _Indomptable_, _Requin_, _Caïman_, and _Terrible_ are sister battle-ships. They were originally laid down in 1877, and the _Terrible_ was only completed ready for sea in 1887. They are constructed like the _Marceau_, of iron and steel, the outer skin of the under-water body being of the former metal; the compound armor is from 13 to 19⅝ inches in thickness, and carries five feet of its seven feet six inches width below the water-line. In each of two pear-shaped barbette towers situated on the longitudinal midship line, and protected by 17¾ inches of armor, a 16.5-inch gun, with its axis twenty-one feet above the water is mounted; in addition there are four 4-inch breech-loading rifles and a secondary battery of rapid-fire guns and torpedo-tubes. The _Indomptable_, launched in September, 1883, made in her trial trip in August, 1886, a speed of 15 knots, and is officially rated as having a sea speed of 13.5 knots. All work upon the partially protected ships _Brennus_ and _Charles Martel_ was stopped in 1886, and their specific appropriation has been transferred to the sum already assigned for the construction of fast cruisers and torpedo-boats.
