Operation Spring Thunder had been formulated by Jiang Yan Hai and the others, then refined in various ways afterward. At present, its execution remained extremely thorough.
Why was it called Spring Thunder? Naturally, because they intended to strike the enemy with thunderous force before spring arrived.
The Descendant was a nuclear submarine, falling within the category of attack nuclear submarines. It was the first nuclear submarine built in this world. After its launch and shakedown cruise, its first mission was to head straight for the British Isles, thousands of miles away.
They had already been underway for nearly ninety days, with the journey alone taking close to sixty. This world had no canals, so they had to take the longest route around.
They could actually have taken a shortcut by passing directly beneath the Arctic ice cap. However, this world lacked sufficient hydrographic data, and no one knew what lay beneath the ice. If they crashed into the deep sea, the losses would be far too great. To be safe, they had sailed on the surface instead.
In any case, the enemy had no way of detecting them. Though the voyage was long, they did not need to remain underwater the entire time, so the crew's mental state was quite good. Along the way, they had even completed quite a few reconnaissance missions.
Those reconnaissance missions were simple. They involved placing solar-powered communication and detection devices along certain coastlines, and those devices served a wide variety of purposes.
They also had no need to worry while lying in wait near the British Isles, so the submarine was almost always in a state where it could receive information at any time. The enemy had no radio detection capabilities, so there was naturally no need to worry about radio exposure.
Thus, communications
