LIST OF VESSELS 



 In total about 290 fishing vessels of this type were built from 1971 to 1994. On the basis of project 503 were built folowing types: "Andrey Smirnov" type - Fishing FreezerTrawler - project 503M, "Tornyy" type - crab-fish freezer longliner - project 503M/K, "Diorit" type - shelf drilling vessel - project 05031, fish oil tanker - project 05037 (503N), research vessel with deep submersible craft - project 1539, research vessel - project 503GOI, experimental vessel for Soviet Naval Forses - project 05035, small intelligence ship for Soviet Naval Forses - project 503R, also were built 6 fishery protection vessels - projects 503M/ROS, 503N/ROS and 503M/RR. Yard number 855 was converted to anti-submarine ship for Soviet Naval Forses. All fishery protection vessels of projects 503M/ROS, 503N/ROS and 503M/RR and also fishery protection vessels "Skat", "Pagella", "Askold Pynko" were transferred to Russian federal frontier patrol service.
Purpose of the vessel:     - pelagic and ground trawl fishing, purse net fishing
    - keep refrigerated fish, transfer of catch to factory vessels

Notices:
        - During construction of a series of vessels of one project, in their design some changes can be made and the above-stated characteristics can be changed insignificantly.
        - The above-stated characteristics are taken on the vessel "Kalamus" with yard No.316 (source - Fishing industry fleet. Reference book. 1990). In brackets are characteristics of first ship "Alpinist" with yard No.201.
