Thomas Hoover - Project Daedalus

"I don't know anything about the radar. I just wanted to check out handling characteristics under different conditions. It was only a minor add-on to the scheduled maneuvers, which is why I didn't-"

"Which is why you didn't include it in your flight report." Ikeda's dark eyes bored into him. "Is that what you expect us to assume?"

The Soviet team was exchanging nervous glances. They all knew Yuri Androv was sometimes what the Americans called a cowboy, but this unauthorized hot-dogging sounded very irresponsible. None of them had heard about it until now.

"An oversight. There was so much-"

"Major Androv," Ikeda interrupted him, "you are on official leave from the Soviet Air Force. No one in this room has the military rank to discipline you. But I would like you to know that we view this infraction as a very grave circumstance."

"You're right. It was stupid." Time to knuckle under, he thought. "Let me formally apologize to the project management, here and now. It was a grave lapse of judgment on my part."

"Yuri Andreevich, I must say I'm astonished," the elder Androv finally spoke up. "I had no idea you would ever take it into your head to do something like this, to violate a formal test sequence."

He smiled weakly. "I just… well, I always like to try and expand the envelope a little, see what a new bird's got in her."

And, he told himself, I did. Just now. I found out two things. First, I can evade the bastards' tracking stations by switching off the transponder, then going "on the deck." I can defeat their network and disappear. I needed to find out if it could be done and now I have. Great! Ikeda's other little slip merely confirms what I'd begun to suspect. This fucking plane is designed to-

"Major Androv, this unacceptable behavior must not be repeated." Ikeda's eyes were filled with anger and his tone carried an unmistakable edge of threat. "Do you understand? Never. This project has far too much at stake to jeopardize it by going outside stipulated procedure."

"I understand." Yuri bowed his head.

"Do you?" The project director's voice rose, uncharacteristically. "If any such reckless action is ever repeated, I warn you now that there will be consequences. Very grave consequences."

Bet your ass there'll be consequences, Yuri thought. Because the next time I do it, I'm going to smoke out Mino Industries' whole game plan. There'll be consequences like you never dreamed of, you smooth-talking, scheming son of a bitch.

Tuesday 8:46 P.M.

"What does it tell you?" Yuri shaded his eyes from the glare of the hangar fluorescents and pointed, directing his father's gaze toward the dark gray of the fuselage above them. The old man squinted and looked up. "Can you see it? The underside is darker, and it's honeycombed. The air scoops, even the engine housings, everywhere. Very faint, but it's there."

Andrei Androv stared a moment before he spoke. "Interesting. Odd I hadn't noticed it before. But I assume that's just part of the skin undersupport."

"Wrong. Just beneath the titanium-composite exterior is some kind of carbon-ferrite material, deliberately extruded into honeycombing. But you almost can't see it in direct light." He placed his hand on his father's shoulder. "Now come on and let me show you something else."

He led the elder Androv toward the truck-mounted stair, gleaming steel, that led up into the open hatch just aft of the wide wings.

"Let's go up into the aft cargo bay. That's where it's exposed."

The Japanese technicians and mechanics were scurrying about, paying them virtually no heed as they mounted the steel steps and then disappeared into the cavernous underbelly of the Daedalus. The interior of the bay was lighted along the perimeter with high-voltage sodium lamps.

"Have you ever been inside here?" Yuri's voice echoed slightly as he asked the question, then waited. He already suspected the answer.

"Of course. The propulsion staff all had a quick tour, several months ago. Back before-"

"Just what I suspected. A quick walk-through. Now I want you to see something else. I'm going to perform an experiment on this 'aluminum' strut." He extracted a pocket knife and quickly opened it.

"This frame looks like metal, right? But watch."

He rammed the blade into the supporting I-beam that ran along the side of the cargo bay.

"Yuri, what-"

It had passed through almost as though the beam were made of Styrofoam.

"It's not metal. It's a layered carbon-carbon composite. Just like the flaps. A damned expensive material, even for them. For the leading edges, maybe even all the exterior, it makes sense, because of the skin temperature in the hypersonic regime. But why in here? Inside? Why use it for these interior structural components?"

"Perhaps it was to economize on weight, I don't know." The old man wrinkled his already-wrinkled brow.

"Wrong again. Now look up there." He directed his father's gaze to the ceiling of the bay. "Notice how the lining is sawtooth-shaped. I've seen this kind of design before. Weight's not the reason."

"So what are you saying?" The old man's confusion was genuine.

"You're out of touch with the real world." He smiled grimly. "Maybe you've been buried at Baikonur too long, with your head in string quartets and classical Greek. This carbon-carbon composite is used for all the structural elements. There's virtually no metal in this plane at all. And the shape of the fuselage, all those sweeping curves and streamlining. It's probably smart aerodynamic design, sure, but it serves another purpose too. This vehicle has been well thought out."

"What do you mean?"

"Don't you get it? Radar. The shape of the fuselage is deliberately designed to diffuse and deflect radar. And all that honeycombing on the underside is radar-absorbing. Then this in here. The carbon-carbon composites used for this airframe, and that saw-toothing up there, will just absorb what radar energy does get through." He turned back. "This vehicle is as radar-defeating as the U.S. Stealth bomber. Maybe more so. Some of our experimental planes use the same techniques."

"But why? I don't understand. There's no reason."

"You're right about that. There's no need for all this radar-evasive design, all these special materials. Unless…" He paused, then checked below to make sure that no technicians were within earshot. "Last night, when I took her down, I maintained the yaw at ninety degrees, making sure their tracking antenna at Katsura could only see the underside of the fuselage. And guess what. The real story slipped out there at the meeting. This plane just vanished off their radar screens. Disappeared. But now Ikeda knows I know."

The elder Androv stared at him. For years people had told him his son was too smart to be a jet jockey. They were right. All these years he'd never given him enough credit. "I think I'm beginning to understand what you're saying. For a space platform to have-"

"Exactly. The underside of this vehicle has an almost nonexistent radar signature. Probably about like a medium-sized bird. All you'd have to do is darken it some more and it's gone. Now what the hell's the purpose?"

The elder Androv didn't respond immediately. He was still puzzling over the staff meeting. He'd never seen the project director so upset. Admittedly Yuri had violated procedures and violated them egregiously, but still… Ikeda's flare of anger was a side of the man not previously witnessed by anybody on the Soviet team.

Also, he continued to wonder at their sudden rush to a hypersonic test flight. Pushing it ahead by months had created a lot of fast-track problems. Why was Mino Industries suddenly in such a hurry? And now, this mystery. Yuri was right. An air-breathing orbital platform for near-space research didn't need to evade radar. The world would be cheering it, not shooting at it. Very puzzling. And troubling.
