Ship project history: Officially were called as the patrol ships (an index "P" from a word "patrol"), actually were the first-ever purpose-built submarine chasers. In total 54 units (Ð11-64) were ordered, but the part was completed as "PC" type decoys (with preservation of original numbers). They were appeared as successful ships.
Modernizations: None
Naval service: P26 was stricken by German mine.
