The Three-Body Problem

One day, Commissar Lei came to speak with Ye. By this time, Yang Weining and Lei Zhicheng had swapped places in her eyes. During those years, Yang, as the highest-ranked technical officer, did not enjoy a high political status, and outside of technical matters he had little authority. He had to be careful with his subordinates, and had to speak politely even to the sentries, lest he be deemed to have an intellectual’s resistant attitude toward thought reform and collaboration with the masses. Thus, whenever he encountered difficulties in his work, Ye became his punching bag. But as Ye gained importance as a technical staff member, Commissar Lei gradually shed his initial rudeness and coldness and became kind toward her.

Commissar Lei said, “Wenjie, by now you’re pretty familiar with the transmission system. This is also Red Coast’s offensive component, its principal part. Can you give me your views of the system as a whole?”

They were sitting at the lip of the steep cliff on Radar Peak, the most secluded spot on the base. The cliff seemed to drop straight off into a bottomless abyss. At first, the spot had frightened Ye, but now she liked to come here by herself.

Ye wasn’t sure how to answer Commissar Lei’s question. She was only responsible for maintaining and repairing equipment and knew nothing about Red Coast as a whole, including its operation, targets, and so on. Indeed, she wasn’t allowed to know. She wasn’t even permitted to be present at the transmission. She pondered the question, began to speak, and stopped herself.

“Go ahead, speak your mind,” Commissar Lei said. He ripped out a blade of grass next to him and played with it absent-mindedly.

“It … is just a radio transmitter.”

“That’s right, just a radio transmitter.” The commissar nodded, satisfied. “Do you know about microwave ovens?”

Ye shook her head.

“They are a luxury plaything of the capitalist West. Food is heated by the energy generated from absorbing microwave radiation. At my previous research station, in order to precisely test the high-temperature aging of certain components, we imported one. After work, we would use it to warm mantou bread, bake a potato, that sort of thing. It’s very interesting: The inside heats up first while the outside remains cold.”

Commissar Lei stood up and paced back and forth. He was so close to the edge of the cliff that it made Ye nervous.

“Red Coast is a microwave oven, and its heating targets are the enemy’s space vessels. If we can apply microwave radiation at a specific power level of one-tenth of a watt to one watt per square centimeter, we’ll be able to disable or destroy many electronic components of satellite communications, radar, and navigation systems.”

Ye finally understood. Even though Red Coast was only a radio transmitter, that didn’t mean it was conventional. The most surprising aspect was its transmission power: as high as twenty-five megawatts! This wasn’t just more powerful than all communication transmissions, but also all radar transmissions. Red Coast relied on a set of gigantic capacitors. Because the power requirements were so high, the transmission circuits were also different from conventional designs. Ye now understood the purpose of such ultrahigh power in the system, but something seemed wrong right away. “The emission from the system seems to be modulated.”

“That’s right. However, the modulation is unlike that used in conventional radio communications. The purpose isn’t to add information, but to use shifting frequencies and amplitudes to penetrate possible shielding by the enemy. Of course, those are still experimental.”

Ye nodded. Many of her questions had now been answered.

“Recently, two target satellites were launched from Jiuquan. The test attacks by Red Coast were completely successful. Temperature inside the satellites reached nearly a thousand degrees, and all instruments and photographic equipment onboard were destroyed. In future wars, Red Coast can effectively strike at the enemy’s communication and reconnaissance satellites, like the KH-8 spy satellites on which the American Imperialists rely, as well as the KH-9, which are about to be launched. The lower-orbit spy satellites of the Soviet Revisionists are even more vulnerable. If necessary, we even have the capacity to destroy the Salyut space station of the Soviet Revisionists and the Skylab station that American Imperialists plan on launching next year.”

“Commissar! What are you telling her?” Someone spoke behind Ye. She turned and saw that it was Yang Weining, who stared at Commissar Lei severely.

“This is for work,” Commissar Lei said, and then left. Yang glanced at Ye without saying anything and followed Lei. Ye was left all by herself.
