(this submarine is fictional) The ss-87 is a tactical submarine put into action after extensive research and testing. The sub is lightly weaponized but highly armored and has a incredible speed. the subs usefulness comes from being overly massive, with it being the length of an aircraft carrier. its engine room takes up 20% of the sub's space, this gigantic committed room propels the sub to 80mph. To use the sub activate one and then 2, afterwards use the torpedo by detaching with 3, and propelling with 456. it is a short range, high accuracy torpedo that can blow a decent chunk out of enemy carriers. (This submarine is gigantic and as expected isn't very practical, it is difficult to control to say the least.) Enjoy! - Nick
