Усередині пускової установки: підводний човен класу «Огайо» та ракета «Трайдент»

The video explains why modern submarines are divided into separate compartments under pressure, not only for structural integrity but for survival. It focuses on the life‑support system that protects the Trident II D5 nuclear missile. The launch of a missile from inside a submarine would normally destroy the vessel, so the crew uses a cold‑launch system that ejects the missile through the ocean surface before the main engines ignite. The video also compares this to land‑based Minuteman III and air‑borne B‑2 Spirit, questioning why billions are spent on underwater nuclear deployment. Unlike vulnerable surface ships or bombers, a submarine can remain hidden in darkness, ready to deliver a final counter‑attack if necessary.
