The major part of the vessels were aged but seemed to be modernized recently of even replaced by newer smaller gunboats. Bases were Chabarowsk and Nikolajewesk. The 200 ton vessels were armed with 2-10cm/3.9” guns and 1 howitzer. The smallest motorboats had a displacement of 20 ton and a 3,7cm/1.46” machinegun.
