Attack Submarines
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants, and merchant vessels. In the Soviet Navy, Soviet and Russian Navy, Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and Ballistic missile submarine, missile submarines. Some attack subs are also armed with submarine-launched cruise missile, cruise missiles, increasing the scope of their potential missions to include land targets. Attack submarines may be either nuclear marine propulsion, nuclear-powered or diesel–electric ("conventionally") powered. In the United States Navy hull classification symbol, naming system, and in the equivalent NATO system (STANAG 1166), nuclear-powered attack submarines are known as SSN (hull classification symbol), SSNs and their anti-submarine warfare, anti-submarine (ASW) diesel–electric predecessors are SSK ...

Periscope Depth
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in Armored car (military), armoured vehicles. More complex periscopes using Prism (optics), prisms or advanced Optical fiber, fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. ...
