Inside the Launch: Ohio Class Submarine & Trident Missile

Why is a modern submarine divided into distinct, pressurized compartments? The answer isn't just about structural integrity—it is about survival. But this life‑support system exists to protect one thing: the Nuclear Trident 2 D5 Missile. Firing a missile inside a submarine would destroy the boat, so how do they do it? They use a high‑pressure "cold launch" to punch the weapon through the ocean surface before the main engines ever turn on. Here is the real mystery: we have the Minuteman 3 on the ground and the B‑2 Spirit in the air. So, why do we spend billions to put nukes under the ocean? Unlike vulnerable silos or bombers, a submarine vanishes. Even if the entire map is wiped clean by nuclear weapons, the sub remains hidden in the dark, ready to launch the final counter‑attack if needed, all in the video ahead.
