The commercial advantages were obvious, and the Junction's far-flung termini had become magnets for trade, all of which must pass through the central junction point (and Manticoran space) to take advantage of them. Manticore's tolls were among the lowest in the galaxy, but simple logistics meant they generated enormous total revenues, and the Kingdom served as a central warehousing and commercial node for hundreds of other worlds.
Yet logistics also made the Junction a threat. If multi-megaton freighters could pass through it, so could superdreadnoughts, and the economic prize it offered was sufficient to make for avaricious neighbors. Manticorans had known that for centuries, but they hadn't worried about it overmuch before the People's Republic of Haven become a threat.
But Haven had become a threat. After almost two T-centuries of deficit spending to shore up an increasingly insolvent welfare state, Haven had decided it had no choice but to turn conquistador to acquire the resources it needed to support its citizens in the style to which they had become accustomed, and the People's Navy had proven its capacity to do just that over the course of the last five decades. Haven already controlled one terminus of the Junction—Trevor's Star, conquered twelve T-years ago—and Honor had no doubt the "Republic" hungered to add the rest of them to its bag. Especially, she thought with a familiar chill, the central nexus, for without Manticore itself, the other termini were of strictly limited utility.
Which was why the Kingdom had annexed Basilisk following its discovery twenty-odd Manticoran years before. The G5 star's single habitable (if one used the term loosely) planet had complicated the decision, for it boasted a sentient native species, and the Liberals had been horrified at the notion of Manticore "conquering" an aboriginal race. The Progressives, on the other hand, had opposed the annexation because they already realized Haven would someday turn its sights on the Silesian Confederacy, which would take them straight past Basilisk. Manticoran sovereignty, they feared, would be seen as a direct threat—a "provocation"—in Havenite eyes, and their idea of foreign policy was to buy Haven off, not irritate it. As for the Conservative Association, anything that threatened to embroil them in galactic affairs beyond their nice, safe borders was anathema in their eyes.
All of which explained why Basilisk had become a bone of incredibly bitter contention among the major political parties. The Centrists and Crown Loyalists had carried the annexation by only the slimmest margin in the House of Lords, despite ample evidence that the Commons (including many of the Liberals' staunchest allies) strongly favored it. But to get it through the Lords at all, the Government had been forced to agree to all sorts of restrictions and limitations—including the incredibly stupid (in Honor's opinion) provision that no permanent fortifications or Fleet bases should be constructed in the system, and that even mobile units there should be kept to a minimum.
Under the circumstances, one might have expected the restriction on the number of ships which could be stationed there to call for sending only the very best, particularly since the volume of trade through the newly discovered terminus had grown by leaps and bounds. In fact, and especially since Sir Edward Janacek had become First Lord of the Admiralty, the opposite was the case.
Janacek wasn't the first, unfortunately, to denigrate Basilisk's importance, but his predecessors at least seemed to have based their feelings on something besides personal politics. The pre-Janacek theory, as far as Honor was able to determine, had been that since they were barred from putting in forces which might stand a chance of holding the system, there was no point making the effort. Thus, even many of those who supported the annexation saw the picket as little more than a trip-wire, advanced scouts whose destruction would be the signal for a response by the Home Fleet direct from Manticore. In short, some of them had argued, if any serious attack was ever mounted, there was no point sacrificing any more ships than necessary simply for the honor of the flag.
Janacek, of course, felt even more strongly than that. Since assuming control of the Admiralty, he had reduced the Basilisk picket below even the stipulated levels, for he saw it as a threat and a liability, not an asset. Left to his own devices, he would no doubt have simply ignored the system completely, and since he couldn't (quite) do that, he could at least see to it that he didn't waste any useful ships on it. And so Basilisk Station had become the punishment station of the Royal Manticoran Navy. Its dumping ground. The place it sent its worst incompetents and those who had incurred Their Lordships' displeasure.
People like Commander Honor Harrington and the crew of HMS Fearless.
CHAPTER FIVE
HMS Fearless decelerated smoothly towards a stop as she passed the inner perimeter of the Junction defenses. She was just under one day out of Manticore orbit, and Manticore System's G0 primary and its G2 companion were dim behind her, reduced to two more stars amid millions, for the Junction lay almost seven light-hours from them.
The duty watch manned their stations alertly, and a stranger on Fearless's bridge might not have recognized the air of gloom which clung to them. But a stranger, Honor thought, reaching up to rub Nimitz's jaw absently, wouldn't have lived with these people for weeks now. A stranger wouldn't recognize their humiliation at being condemned to Basilisk Station, or the way they'd withdrawn ever deeper into their shells until the duties they performed were all they really had in common with their captain.
She leaned back, hiding her desire to sigh sadly behind a calm face, and watched the tactical display. Fearless's projected vector stretched across it, terminating right on the half light-second outbound departure threshold of the Junction. The light cruiser's green bead tracked steadily down the thin line, threading its way through the mammoth defenses, and even in her own depression, Honor felt a familiar tingle at the firepower ringing the invisible doorway between the stars.
The smallest fortress out there massed close to sixteen million tons, twice as much as a superdreadnought, and its weapons-to-mass ratio was far higher. The forts weren't hyper-capable, for they used mass a warship might have devoted to its hyper generators and Warshawski sails to pack in still more firepower, but they were far more than immobile weapon platforms. They had to be.
Each of those forts maintained a stand-by battle watch and a 360º sidewall "bubble" at all times, but no one at this end of the Junction could know anyone was coming through it until they arrived, and no one could remain eternally vigilant. Thus a sneak attack—from, say, Trevor's Star—would always have the advantage of surprise; the attacker would arrive ready for battle, already seeking out targets for his weapons, while the defenders were still reacting to his arrival in their midst.
That was why no defensive planner placed his permanent defenses closer than a half million kilometers or so to a junction. If a hostile task force emerged within energy weapon range of the defenses, those defenses would be destroyed before they could reply, but ships transiting a wormhole junction arrived with a normal-space velocity of barely a few dozen kilometers per second, far too little for a high-speed attack run. With the closest forts so far from him and too little speed for a quick run-in to energy weapon range, any attacker must rely on missiles, and even impeller-drive missiles would require almost thirty-five seconds to reach them. Thus the forts' duty watches—in theory, at least—had time to reach full readiness while the weapons accelerated towards them. In practice, Honor suspected, most of them would still be coming on-line when the missiles arrived, which was why their point defense (unlike their offensive weaponry) was designed for emergency computer override even in peacetime.
In time of war, the forts would be augmented by thickly seeded remote laser platforms—old-fashioned, bomb-pumped laser satellites—much closer in and programmed to automatically engage anything not positively identified as friendly, but such measures were never used in peacetime. Accidents could always happen, and the accidental destruction of a passenger liner whose IFF wasn't recognized could be embarrassing, to say the very least. An attacker would still have sufficient surprise advantage
for his energy batteries to kill a lot of satellites before they could respond, but enough of them would survive to handle him very roughly indeed.
Nonetheless, heavy losses could be anticipated in the inner fortress ring under the best possible circumstances, so the "forts" in the outer rings had to be able to move to fill in the gaps and mass upon an attacker. Their maximum acceleration rates were low, well under a hundred gravities, but their initial positions had been very carefully planned. Their acceleration would be enough to intercept attacking forces headed in-system, and their engines were sufficiently powerful to generate impeller wedges and sidewalls to protect them.
Nor was the threat of a wormhole assault the only reason for those forts, for the twenty-three and a half hours Fearless had required to reach the Junction underscored another defensive problem. Both wormholes and stars had hyper limits, within which no ship could enter or leave hyper. For junctions, the limit was, less than a million kilometers; for a G0 star, it was twenty-two light-minutes. But any wormhole terminus and the star with which it was associated created a roughly cone-shaped volume of mutual interference, lethal to any ship passing through it, in hyper-space's lowest bands. The danger volume wasn't perfectly cone-shaped, and each wormhole and star created its own unique threat zone, which generally threw off spurs about the wormhole itself. Because the Manticore System was a binary, with danger volumes for each star, the Junction's closed areas were more complicated than most, but there were always clear zones around the outer perimeter of any wormhole, gaps through which the wormhole could be approached from hyper. Which meant that while a defensive fleet stationed in orbit around Manticore or Gryphon would require a full day to reach the Junction through n-space, an assault from outside the system could (in theory, at least) drop out of hyper right on top of the Junction and already shooting.
In fact, it was less simple than that. Cutting a translation out of hyper that close was virtually impossible, so the attackers would almost certainly have to maneuver in n-space to get into attack range, which should give the forts time to detect them and, using their mobility, redeploy to meet their attack.
Yet for all their numbers, firepower, and mobility, the fortresses were too weak to stop a worst-case, multiple-transit attack by an opponent as powerful as the Havenite Navy. And that, she told herself moodily as Fearless killed the last of her speed and slid to a halt, was the real reason Manticore had annexed Basilisk in the first place.
The central nexus was the key to any wormhole junction. Ships could transit from the central nexus to any secondary terminus and from any secondary terminus to the central nexus, but they could not transit directly from one secondary terminus to another. Economically, that gave Manticore a tremendous advantage, even against someone who might control two or more of the Manticore Junction's termini; militarily, the reverse was true.
There was an inviolable ceiling, varying somewhat from junction to junction, on the maximum tonnage which could transit a wormhole junction terminus simultaneously. In Manticore's case, it lay in the region of two hundred million tons, which set the upper limit on any assault wave the RMN could dispatch to any single Junction terminus. Yet each use of a given terminus-to-terminus route created a "transit window"—a temporary destabilization of that route for a period proportionate to the square of the mass making transit. A single four-million-ton freighter's transit window was a bare twenty-five seconds, but a two-hundred-million-ton assault wave would shut down its route for over seventeen hours, during which it could neither receive reinforcements nor retreat whence it had come. Which meant, of course, that if an attacker chose to use a large assault wave, he'd better be absolutely certain that wave was nasty enough to win.
But if the attacker controlled more than a single secondary terminus, he could send the same tonnage to the central nexus through each of them without worrying about transit windows, since none would use exactly the same route. Choreographing such an assault would require meticulous planning and synchronization—not an easy matter for fleets hundreds of light-years apart, however good the staff work—yet if it could be pulled off, it would allow an attack in such strength that no conceivable fortifications could stop it.
Not even Manticore's, Honor thought as Fearless slowed to rest relative to the Junction. Even though the Junction fortresses accounted for almost thirty percent of the RMN's budget, the security—or at least neutrality—of the Junction's other termini simply had to be guaranteed.
"We have readiness clearance from Junction Central, Ma'am," Lieutenant Webster announced. "Number eight for transit."
"Thank you, Com." She glanced at her maneuvering display as the scarlet numeral "8" appeared beside Fearless's cursor, then turned her gaze to the duty helmsman. McKeon sat silently beside Lieutenant Venizelos at Tactical, but her eyes passed over him without even acknowledging his presence. "Put us in the outbound lane, Chief Killian."
"Aye, aye, Ma'am. Coming to outbound heading." Killian fell silent for a moment, then, "In the lane, Captain."
Honor nodded her satisfaction and glanced up at the visual display just as a stupendous bulk carrier erupted from the junction. It was an incredible sight, one she never tired of, and the display's magnification brought it to arm's length. That ship had to mass over five million tons, yet it blinked into sight like some sort of insubstantial ghost, a soap bubble that solidified into megatons of alloy in the blink of an eye. Its huge, immaterial Warshawski sails were circular, azure mirrors, bright and brilliant for just an instant as radiant transit energy bled quickly into nothingness, and then it folded its wings. The invisible sails reconfigured into impeller stress bands, and the freighter slowly gathered way, accelerating out of the nexus while it cleared its final destination with Junction Central and requested insertion into the proper outbound lane to continue its voyage.
Fearless moved steadily forward with the other outbound vessels. In time of peace, she had no greater priority than any of the gargantuan merchantmen who dwarfed her to insignificance, and Honor leaned back in her chair to savor the bustle and purposeful energy of the Junction in action.
Under normal circumstances, the Junction handled inbound and outbound vessels at an average rate of one every three minutes, day in and day out, year after year. Freight carriers, survey vessels, passenger ships, inner-world colony transports, private couriers and mail packets, warships of friendly powers—the volume of traffic was incredible, and avoiding collisions in normal-space required unrelenting concentration by the controllers. The entire Junction was a sphere scarcely a light-second in diameter, and while that should have been plenty of space, each terminus had its own outbound and inbound vector. Transiting to the proper destination required that those vectors be adhered to very precisely indeed (especially when not even Junction Central knew exactly who might be inbound from where at any given moment), and that meant traffic was confined to extremely limited areas of the Junction's volume.
Chief Killian held Fearless's place in the outbound queue without further orders, and Honor punched up Engineering as they neared the departure beacon. Commander Santos appeared on her small com screen.
"Commander. Stand by to reconfigure to Warshawski sail on my command."
"Aye, Ma'am. Standing by to reconfigure."
Honor nodded, watching the freighter ahead of them drift further forward, hesitate for just an instant, and then blink out of visibility. The numeral on her maneuvering display changed to "1," and she turned to Webster and quirked an eyebrow, waiting out the seconds until he nodded.
"We're cleared to transit, Ma'am," he reported.
"Very good. Transmit my thanks to Junction Central," she said, and looked back at Chief Killian. "Take us in, Helm."
"Aye, aye, Ma'am."
Fearless drifted forward at a mere twenty gravities' acceleration, aligning herself perfectly on the invisible rails of the Junction, and Honor watched her display intently. Thank God for computers. If she'd had to work out the math for this sort of thing, she'd probabl
y have cut her own throat years ago, but computers didn't mind if the person using them was a mathematical idiot. All they needed was the right input, and, unlike certain Academy instructors she could name, they didn't wait with exaggerated patience until they got it, either.
Fearless's light code flashed bright green as the cruiser settled into exact position, and Honor nodded to Santos.
"Rig foresail for transit."
"Aye, aye, Ma'am. Rigging foresail—now."
No observer would have noted any visible change in the cruiser, but Honor's instrumentation told the tale as Fearless's impeller wedge dropped abruptly to half-strength. Her forward nodes no longer generated their portion of the normal-space stress bands; instead, they had reconfigured to produce a circular disk of focused gravitation that extended for over three hundred kilometers in every direction from the cruiser's hull. The Warshawski sail, useless in normal-space, was the secret of hyper travel, and the Junction was simply a focused funnel of hyper-space, like the eye of a hurricane frozen forever in normal-space terms.
"Stand by to rig aftersail on my mark," Honor murmured as Fearless continued to creep forward under the power of her aft-impellers alone. A new readout flickered to life, and she watched its numerals dance steadily upward as the foresail moved deeper and deeper into the Junction. There was a safety margin of almost fifteen seconds either way, but no captain wanted to look sloppy in a maneuver like this, and—
The twinkling numbers crossed the threshold. The foresail was now drawing sufficient power from the tortured grav waves twisting eternally through the Junction to provide movement, and she nodded sharply to Santos.
"Rig aftersail now," she said crisply.
