Despite that, he couldn’t really fault the colonel’s decision.
O’Connell’s 1/75th had the toughest and most critical assignment in Brave
Fortune, and Carrerra, the 2/75this CO, was a veteran Ranger-someone
Gener had worked with for years. So naturally, the colonel wanted to be where he was likely to be needed most.
O’Connell frowned, irritated with himself for having wasted even a second of precious time worrying about something he couldn’t control. He looked up.
“Round up the guys, Pete. I want to see all company commanders here at thirteen hundred hours. And tell Professor Levi I’d like to talk to him-now. “
Prof. Esher Levi eyed the short, dark-haired American officer warily. In the two days since he’d arrived at Hunter, he’d met O’Connell only briefly-at meals and once after a rigorous session with the Rangers he was training to handle South Africa’s nuclear weapons. And each time, he’d sensed two conflicting emotions vying with each other inside the
American officer: gratitude for Levi’s help and deep outrage at the fact that Israel’s cooperation with South Africa made it necessary for his men to risk their lives in the first place. It made for a somewhat complicated working relationship.
“You wanted to see me, Colonel?”
“Yeah. For two reasons.” O’Connell pushed an enhanced satellite photo across his desk and watched as Levi picked it up. The photo showed a squat, square building in the center of Pelindaba’s scientific complex.
“Recognize that?”
Levi nodded. He’d spent two years of his life in and around Pelindaba’s centrifuge uranium-enrichment plant-the key component of South Africa’s top-secret nuclear weapons program.
Only slightly more than seven-tenths of one percent of raw uranium ore is actually U-235-the uranium isotope needed for bomb-making. The other ninety-nine-odd percent is U238, an almost identical isotope. Separating the two to produce enriched, weapons-grade uranium is an extraordinarily difficult, costly, and time-consuming process. And only the fact that
U-235 weighs slightly less than U-238 makes it possible at all.
In centrifuge enrichment, uranium hexafluoride-a gaseous combination of natural uranium and fluorine-is whirled round and round at high speed inside a tall, thin centrifuge. A small fraction of the slightly heavier
U-238 is thrown to the outside of the centrifuge and can be removed, leaving behind gas with a slightly higher concentration of U-235. The process is repeated over and over and over again until more than ninety percent of the remaining uranium is U-235.
Levi smiled to himself. In many ways, he thought, uranium enrichment closely resembled the fabled infinite series of monkeys pounding away on an infinite number of typewriters to produce the complete works of
William Shakespeare. Obtaining usable quantities of bomb-grade material required a great many machines working at high speed for a very long time.
He scanned the photo of Pelindaba’s enrichment plant again, marveling at the technical achievement the picture represented. Despite being taken by an American satellite orbiting several hundred miles above the earth’s atmosphere, it looked as though it had been snapped only a few feet off the ground. Details of the facility’s heavily guarded doorways and rooftop air-conditioning system were plainly visible. Nevertheless, the shot of the plant’s square, windowless exterior revealed nothing of its inner complexity.
Like an iceberg, most of the South African uranium enrichment plant was below the surface-a design feature that made it easier to maintain a constant temperature inside. A central cascade hall housed more than twenty thousand centrifuges-each only thirty centimeters wide and seven meters high-an-anged and mounted in rows and connected to form ninety distinct enrichment stages. Tens of kilometers of small-bore piping ran through the plant-feeding in fresh uranium hexafluoride, carrying off
U-238 waste, and moving batches of ever more enriched uranium from stage to stage.
Levi passed the photo back to O’Connell.
“You have sow question about the facility, Colonel?”
“Not exactly.” The American frowned.
“I need a quick, efficient way to destroy the damned place.”
Levi wasn’t surprised. It was a logical step. Seizing South
Africa’s nuclear stockpile without wrecking its uranium enrichment plant made little long-term sense. Why go to a lot of trouble to take a few bullets away while leaving the whole ammunition factory behind?
Levi steepled long, graceful hands-hands his ex-wife had thought more appropriate for a surgeon than a nuclear physicist. It was an intriguing problem. What was the best way to wreck thoroughly Pelindaba’s enrichment plant? Placing conventional demolitions meant capturing the facility itself and then spending a fair amount of time wiring a large number of charges together. You’d need a lot of explosive power to destroy everything.
Power. That might be it. Levi sat up straighter, a series of half-formed ideas and concepts floating through his brain. He looked across at
O’Connell.
“There could be a relatively simple way to do such a thing,
Colonel.” His fingers beat a quick, distracted beat on the desk.
“However,
I will need a little time to work out all the details.”
O’Connell nodded briskly.
“Good. Because a little time is all we’ve got.”
His eyes narrowed.
“Which brings me to my second reason for wanting to see you. Can you get Lieutenant Vaughn’s special weapons team ready to go by the twenty-ninth?”
“Impossible.” Levi shook his head decisively.
“Your Rangers are good students, Colonel, but even they cannot learn everything they will need to know in anything less than a week.”
“I see.” The American officer sounded disappointed, but not particularly surprised. He glanced down at a manila folder in front of him. Levi saw a small tag that bore his name.
“I understand you’re an Israeli Defense Force reservist, Professor.
“That’s correct. Just like any other adult male in my country.” Levi looked curiously at the folder. Had Jerusalem given the Americans his whole personnel record?
“Paratrooper?”
Levi smiled and shook his head.
“Nothing so glamorous, Colonel. As a senior scientist, I now have an exemption from active duty, but I wasn’t quite so fortunate as a young student.
Consequently, I spent several long months as a lowly infantryman. Why do you ask?”
O’Connell slid a telex across the desk.
“Because your government’s called you back to the colors, Professor. As of six hundred hours tomorrow, you’re to consider yourself attached to my battalion in a military capacity.”
Levi stared at the message form for several seconds.
“But why? I don’t understand.”
Now it was O’Connell’s turn to smile.
“It’s pretty simple, Private Levi.
Washington’s changed the timetable. We’re jumping into Pelindaba on the twenty-ninth-a week ahead of schedule. And I need a special weapons team led by an expert. Unfortunately, you’ve just con finned that my troopers won’t be ready by then. So you’re going to be my expert.”
Levi felt his mouth drop open and stay open.
Visibly amused, the American officer nodded briskly and stuck out his hand.
“Welcome to the Rangers, Professor.” His thin smile turned into a wide grin.
“You’re just lucky that lea ming how to jump out of airplanes isn’t quite as complicated as lea ming how to assemble and disassemble Abombs. “
