Were the Imperatritsa Mariya-class ships pocket battleships?
Short answerNo; they were smaller Black Sea battleships designed for their theater, perhaps better described as second-class battleships.
NotesThe Imperatritsa Mariya class does not fit the pocket-battleship label. These were smaller battleships designed around the requirements of the Black Sea. A term such as second-class battleship might describe their scale more closely, although that suggestion remains tentative. Their size followed theater and mission.
