Over the years, the main weapon of submarines were torpedoes and mines, but with the improvement of technology on their decks the rockets arrived. First they were fired from a water position, but very rapidly they were developed to fire from a secret underwater position. Generally, these missiles can be divided into ballistic missiles fired from vertical launchers and rockets fired from torpedo launchers. The second are utilized to combat submarines and coastal and land purposes. Of course, specified rockets can besides be fired vertically, but then the ship must have separate vertical torpedo launchers in addition to the torpedo launchers. The disadvantage of utilizing vertical launchers is the request to enlarge ship dimensions. In the case of submarines operating on oceans and large seas, this is not as crucial as ships intended to operate on shallow and closed seas.
