Project 865 Piranha (Russian: Проект 865 «Пиранья»), NATO reporting name "Losos", is a Russian supersmall experimental submarine.
The Losos was designed for special operations and engaging surface ships located offshore, and is thus very durable and almost completely silent.
The hull is made of a titanium alloy, reducing the effectiveness of mines.
Only two Losos class submarines were built, the MS-520 and the MS-521. Original planning called for a total of 12 Project 865 Piranya Submarine to be constructed, this was eventually reduced to 6, then just the two.[1] Launched in 1986 and 1990, respectively, they are in reserve but are expected to soon be discarded.
