U.S.S. ERIE: SHIP SPECIFICATIONS
The U.S.S. ERIE, like her sister ship the U.S.S. CHARLESTON, was designed to conform to the requirements of the London Naval Treaty of 1930. Per Article VIII (b) of the Treaty, signatories were allowed to construct an unlimited number of sloops (gunboats) having: a displacement not exceeding 2,000 tons; no torpedo tubes; a maximum cruising speed of 20 knots; and, no more than four guns above 3.1 inch in caliber (none of which could exceed 6.1 inch in caliber).
As can be seen in viewing her specifications below, the ERIE conformed to these requirements. The one possible exception had to do with protective (armor) plating. Since gunboats were viewed as minor combatants, it might have been assumed that this was disallowed. However, U.S. Navy officials decided that this was allowable under the Treaty, and so certain spaces on the ERIE (see OTHER FEATURES section of specifications below) were protected with armor plating that was anywhere between 1 and 4 inches thick.
These specifications include any modifications made during the last major overhaul of the ERIE, during the months of August and September 1942, at the Mechanical Division, Balboa, Canal Zone.
The info listed below is taken from: U.S.S. ERIE PG-50 Booklet of General Plans (completed July 31, 1934); Naval Expenditures 1937 (Washington, D.C.: United States Government Printing Office, 1938); Ships Data, U.S. Naval Vessels (Washington, D.C.: United States Government Printing Office, 1938); K. J. Bauer and S.S. Roberts, Register of Ships of the U.S. Navy, 1775-1990 (Westport: Greenwood Press, 1991); and, U.S. Navy reports dealing with the torpedoing and loss of the ERIE.
The ERIE’s 36-ft. motor launch and 35-ft. motor boat were removed in 1942 (the exact time is unknown).
