the blorno class sub was first launched in 1987 as a coastal patrol sub to secretly sink and destroy potential enemy ships. but while most of the wars happened else where some were sent to do joint naval missions, the blorno was only armed with torpedoes which some were designed to sink ships in shallow waters such as ports. the sub is at least 500ft and are build with incredible reinforced super structure to allow the sub to tank out suppressive amount of damage and still survive, plus these submarines can remain submerged in any condition for months on end and have an incredible travel distance due to its self-rechargeable generators. For its two conning towers, they're both used for checking the surroundings and to see what ships are up to if theirs more then one to survey
