Gunboats

[Carthaginian]

The third class of 'mass cruiser', the Corpus Christi class is ostensibly an improvement on the two earlier classes. Their alleged improvements involved weakening the gunnery, removing the puny 55pdr guns without enhancing the 3" battery, and inreasing range at the expense of accomodation. As with the earlier classes, these ships are rusting away in southern California.

A new, but scarcely improved, class of cruiser was laid down in 1889. The Inverness class mounts the new 4" 25pdr gun, and is capable of 19 knots. There is, however, an excessively wide range of light guns, mixing 3pdrs and 6pdrs, and only 4 25pdrs are mounted, giving a broadside of only 2 guns.

The oldest cruiser of the CSN that approaches modern standards, the Laredo class mounts an admirable battery of eight 25pdr guns, with four 19.5" torpedo tubes providing added punch against large ships. Although less seaworthy than earlier ships, these are still potent cruisers and good seaboats.

Well armed, fast cruisers, mounting ten 25pdr guns and six 19.5" torpedoes. Long ranged, their sole shortcoming is their comparatively low speed.
