In 1860 a new range of types appeared in the French Navy, the prominent feature throughout being the extreme development of speed and steaming capacity, combined with medium sail-power and a minimum battery-power, although here the French introduced the rifled gun as an offset to the heavier calibres of American smooth-bores, the primitive type of the rifle leaving it inferior to the latter in power. In the first rate appears a development of the English Challenger class. ========+========+=============+======+===================== RATE. | NAME. |DISPLACEMENT.|SPEED.| BATTERY. --------+--------+-------------+------+--------------------- | | Tons. |Knots.| First |Venus | 2,700 | 12.7 | XIV 6½-inch rifles, | | | | VIII 6-inch smooth. | | | | Second |Decrès | 1,770 | 12 | II 6½-inch rifles, | | | | IV 5¾-inch rifles. | | | | Third |Talisman| 1,300 | 12.4 | II 6½-inch rifles, | | | | IV 4¾-inch rifles. | | | | Gun-boat|Adonis | 730 | 9.3 |IV 4¾-inch rifles. --------+--------+-------------+------+--------------------- The corresponding new types of the United States Navy as they appeared in 1862, excluding the frigates, although the Franklin appeared after this date as the last of this type, were: ========+==========+=============+======+===================== RATE | NAME. |DISPLACEMENT.|SPEED.| BATTERY. --------+----------+-------------+------+---------------------- | | Tons. |Knots.| | Hartford | 2,900 | 10.5 | II 11-inch, | | | | XVIII 9-inch smooth, | | | | I 5¼-inch rifle.
