The duty watch manned their stations alertly, and a stranger on
She leaned back, hiding her desire to sigh sadly behind a calm face, and watched the tactical display.
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 360° 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.
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
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
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
But if the attacker controlled more than a single secondary terminus, he could send the same tonnage to the central nexus through
Not even Manticore's, Honor thought as
'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
'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.
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-
