Chapter 478: Chapter 229: Eradicating the Root Cause Chapter 478: Chapter 229: Eradicating the Root Cause Yan Fei had taken out two US Navy warships when he spotted a Los Angeles-class nuclear submarine attempting to flee beneath the surface. But Yan Fei was here tonight for revenge and naturally wouldn't let the Los Angeles-class attack submarine escape.

Thus, under Yan Fei's control, the stationary drone restarted and swiftly caught up to the fleeing attack submarine. One glided underwater, the other flew in the sky, so the drone quickly caught up with the escaping attack submarine. When it arrived above the nuclear attack submarine, the drone began to rapidly descend, then it dove into the sea with an exceptionally graceful posture.

No sooner had the drone entered the water than its entire body quickly transformed. Its nose became finer and longer, its massive wings swiftly retracted to the back, turning into the most suitable streamlined shape for underwater travel. Then, a dark torpedo tube appeared on the underbelly of the drone. Inside this torpedo tube was an AGM-129 stealth cruise missile, ready to be launched.

The drone quickly dived, reaching 450 meters below the sea surface in a short time. It then maintained this depth and pursued the diagonally upward attack submarine. Powered by strong energy points, the drone overcame the water's resistance and continually increased its underwater speed. Soon, the drone's undersea speed reached 250 kilometers/hour. At this velocity, it became exceedingly difficult for the drone to accelerate further, and Yan Fei soon realized that 250 kilometers/hour was the drone's maximum speed underwater.

Underwater, due to the enormous resistance of seawater, most submerged objects cannot travel very fast. For instance, this US Navy Los Angeles-class attack submarine's top speed was only 32 knots, less than 60 kilometers/hour. The drone's underwater speed of 250 kilometers, far exceeded the submarine's speed. This was an extravagant velocity; even the best sports cars on land couldn't achieve such speed, much less underwater. Thus, the drone easily caught up to the attack submarine with just a little effort.

After another upgrade, the noise made by the drone while submerged was now on par with the background noise of the ocean, rendering it undetectable to the sonar equipment of various naval warships. For them, the underwater drone was also stealthy. Even if the drone made slightly more noise when traveling at full speed underwater, it was essentially undetectable. So when the drone was within 500 meters of the US attack submarine, the vessel hadn't noticed the drone's presence at all and kept rushing towards the US military base on Okinawa Island.

Once in the optimal attack position, the drone's body shook, and the AGM-129 stealth cruise missile within the torpedo tube was quickly launched. Right after this first AGM-129 stealth cruise missile was fired, another identical one appeared in the tube and was also launched, followed by yet another AGM-129 stealth cruise missile materializing in the tube.

The two AGM-129 stealth cruise missiles targeted the Los Angeles-class attack submarine ahead. Guided by quantum radar, they moved swiftly underwater. The AGM-129 was a stealth missile in the air and became a stealth torpedo underwater. As it advanced rapidly below the sea surface, it produced almost no bubbles and made very little noise, so it remained undetected by the US attack submarine.

However, as the two AGM-129 stealth cruise missiles neared the attack submarine, the sound of the bubbles from their tails finally caught the attention of the submarine. The attack submarine immediately realized it was being targeted by unidentified torpedoes and was in danger, so they quickly sounded the battle alarm.

Unfortunately, the Los Angeles-class attack submarine's reaction was too late. The AGM-129 stealth cruise missiles had launched from a very close distance, and their propulsion attack speed was extremely fast. Therefore, although the submarine had detected the incoming torpedoes, it couldn't respond effectively in time. Then the submarine's hull trembled as it was struck by an AGM-129 stealth cruise missile.

In the pitch-black depths of the sea at 400 meters, suddenly there was a flash of bright light, followed by a massive bubble which rapidly disappeared under the pressure of the seabed. Just from this one hit, the Los Angeles-class attack submarine was left with a gaping hole. Under the ferocious attack of the AGM-129 stealth cruise missile, the robust hull hailed as the strongest in defense was thoroughly penetrated.

As soon as the US attack submarine was breached by the torpedo, a deluge of sea water began to rush into the hull. But this was not the worst of it. Guided by the drone's quantum radar, another AGM-129 stealth cruise missile approached the submarine. It entered through the existing hole into the interior of the attack submarine and then exploded violently. The submarine swelled like an inflating balloon and then completely burst open, breaking into pieces before crumbling under the immense water pressure and sinking into the depths of the sea.
