| Beginning in 1872 the Navy categorized its ships in four rates, 1st through 4th. The first three rates were based on displacement tonnage while the fourth rate was initially a miscellaneous collection of small vessels beginning with a wooden double-ender serving as a dispatch vessel, three former paddle blockade runners, two converted tugs, and a screw dispatch vessel. The largest of these was Tallapoosa at 1173 tons and the smallest Pinta at 450 tons. |

USS Palos (1865-1893) Asiatic Station, 1870-1893. Anchored in the Han River, Korea, in May-June 1871, showing early alterations for use as a small crusing gunboat. During this punative operation she towed barges of the landing party during landing operations on 10 June 1871. By 1884 she had been built up further, in the same manner as Pinta, below.

| Note: On 3 March 1885 Congress authorized "one light gunboat of about 800 tons displacement" (Petrel), along with the "heavily armed gunboat" Yorktown. Being smaller than Yorktown, Petrel with four 6" guns and a speed of only 11.5 knots came closer to the gunboat concept of the 1881 Naval Advisory Board. |
