Military Black Technology: I Want to Build a Space Carrier

My name is Lu Zhe, I have awakened the black technology system, and the system wants me to build a space carrier. [Xuanyuan-class interstellar battle carrier: the deep space sword of human civilization] The 1,280-meter-long Xuanyuan-class mothership is mankind's first mobile fortress with interstellar combat capabilities. It uses six deuterium and tritium fusion reactors (a single reactor output is 4.8 Terawatts) as the core power, and is equipped with a magnetic confinement engine to achieve 0.05 Times the speed of light, and the earth-to-fire orbit only takes 5 days. The hull is covered with a five-layer composite defense system: quantum sensing radar achieves 1 astronomical unit light speed early warning, gradient armor (tantalum hafnium carbide ceramic/metallic glass) equivalent to 18 meters of homogeneous steel protection, and a megawatt laser array that can destroy targets thousands of kilometers away in 0.3 Seconds. The main weapon "God's Punishment" gamma ray cannon can vaporize asteroids with a diameter of 50 kilometers, and cooperates with 36 aerospace fighters and billion-level nano-swarms to form a full-area strike network. The shipboard "Hetu" quantum-AI center dominates the battlefield with a decision-making delay of 0.00017 Seconds, and the nanorobots can repair 4.2 Tons of damage per minute. The annular living area simulates 0.6G gravity, and the ecological closed-loop system supports the long-term survival of 500 people. The gene pool and knowledge crystals of human civilization are etched at the seams of its armor, sublimating the war machine into an ark of civilization - even if the earth is annihilated, Xuanyuan will be the fire for human existence. This ship marks the official entry of mankind into Type II civilization, rewriting the boundaries of power in the universe with a body of steel. Key parameters: Mass 820,000 tons/speed 15,000km/s/combat radius 3 billion kilometers.
