In one of Adenauer's and Edwards' brainstorming sessions with Michelle, however, Edwards had pointed out a new possibility which Apollo made possible. Fast as the Ghost Rider platforms were, they were immensely slower than an MDM. They had to be, since stealth and long endurance were completely incompatible with the massive acceleration rates produced by an attack missile's impeller wedge in its brief, incredibly un-stealthy lifetime. But Apollo was designed to combine and analyze the readings from the attack missiles slaved to it . . . and to transmit that analysis back to the launching ship at FTL speed. Michelle and Adenauer had grasped his point immediately and run with it, and this simulation was designed to test what they'd come up with. What Adenauer had done was to fire a single Apollo pod thirty seconds before they fired a complete squadron salvo. And that pod was now one minute's flight from the "unknown impeller wedges" eighty-two million kilometers fromArtemis.
"Jettisoning the shrouds now," Diego reported as the first pod's missiles reached Point Alpha.
"Acknowledged," Adenauer replied.
The shroud-jettisoning maneuver had been programmed into the missiles before launch. Unlike any previous attack missile, the Mark 23s in an Apollo pod were fitted with protective shrouds intended to shield their sensors from the particle erosion of extended ballistic flight profiles at relativistic speeds. Most missiles didn't really need anything of the sort, since their impeller wedges incorporated particle screening. They were capable of maintaining a separate particle screen—briefly, at least—as long as they retained on-board power, even after the wedge went down, but that screening was far less efficient than a starship's particle screens. For the most part, that hadn't mattered, since any ballistic component of a "standard" attack profile was going to be brief, at best. But with Apollo, very long-range attacks, with lengthy ballistic components built into them, had suddenly become feasible. That capability, however, would be of limited usefulness if particle erosion had blinded the missiles before they ever got a chance to see their targets.
Now the jettisoning command blew the shrouds, and the sensors they had protected came on-line. Of course, the missiles were 72,998,260 kilometers from Artemis. That was over four light-minutes, which in the old days (like five or six T-years ago) would have meant any transmission from them would take four minutes to reach Artemis.
With the FTL grav-pulse transceiver built into the Mark 23-E, however, it took barely four seconds.
The display in front of Adenauer blossomed suddenly with icons as the first missile pod's Apollo faithfully reported what its brood could see, now that their eyes had been opened. The light codes of three hostile superdreadnoughts, screened by three light cruisers and a quartet of destroyers, burned crisp and clear, and for a heartbeat, the tactical officer did absolutely nothing. She simply sat there, gazing at the display, her face expressionless. But Michelle had come to know Adenauer better, especially over the last six days. She knew the commander was operating almost in fugue state. She wasn't actually even looking at the plot. She was simply . . . absorbing it. And then, suddenly, her hands came to life on her console.
The missiles in the attack salvo had been preloaded with dozens of possible attack and EW profiles. Now Adenauer's flying fingers transmitted a series of commands which selected from the menu of preprogrammed options. One command designated the superdreadnoughts as the attack missiles' targets. Another told the Dazzlers and Dragon's Teeth seeded into the salvo when to bring their EW systems up, and in what sequence. A third told the attack missiles when to bring up their final drive stages and what penetration profile to adopt when they hit the enemy force's missile-defense envelope. And a fourth told the Mark 23-Es when and how they should take over and restructure her commands if the enemy suddenly did something outside the parameters of her chosen attack patterns.
Entering those commands took her twenty-five seconds, in which the attack missiles traveled another 3,451,000 kilometers. It took just under four seconds for her commands to reach from Artemis to the Apollos. It took another twelve seconds for her instructions to be receipted, triple-checked, and confirmed by the Apollo AIs while the shrouds on the attack missiles were jettisoned. Forty-five seconds after the first pod's missiles had jettisoned their shrouds, the follow-on salvo opened its eyes, looked ahead, and saw its targets, still two and a quarter million kilometers in front of it. They were 4.4 light-minutes from Artemis . . . but their targeting orders were less than sixty seconds old, and the computers which had further refined and analyzed the reports from the first pod's Apollo were those of a superdreadnought, not a missile, however capable.
The simulated targets' fire control had only a relatively imprecise idea of where to look for the attack missiles before their third-stage drives came suddenly on-line. They'd still been so far out when they shut down for the ballistic leg of their flight that the defenders' on-board sensors hadn't been able to fully localize them. The target ships had gotten enough to predict their positions to within only a few percentage points of error, but at those velocities, and on such an enormous "battlefield," even tiny uncertainties made precise targeting impossible. And precise targeting was exactly what was necessary for a counter-missile to hit an attack missile at extended range.
The defenders saw the Mark 23s clearly when the attack missiles' final stages came suddenly and abruptly to life, but by then it was already too late. There was no time for any long-range counter-missile launch, and even the short-range CMs had rushed targeting solutions. Worse, the EW platforms supporting the attack came on-line at the worst possible moment for the defenders. The counter-missiles' rudimentary sensors were totally outclassed, and there was no time for missile-defense officers to analyze the Manticoran EW patterns. Point defense clusters blazed desperately in a last-ditch effort to stop the MDMs hurtling in on the superdreadnoughts, but there were too many of them, they were closing too quickly, and the ballistic approach had robbed the defenders of too much tracking time. Many of the Mark 23s were destroyed short of target, but not enough.
The imagery on Adenauer's plot froze abruptly as the attack missiles and their Apollos slammed into their targets, were picked off by the defenses, or self-destructed at the end of their programmed runs. For an instant or two, the plot simply stayed that way. But then it came abruptly back to life once more. Just as a single pod had preceded the attack wave, another single pod followed in its wake. Its missiles had jettisoned their shrouds at the same moment the attack missiles executed their final runs, and Michelle watched in something very like disbelief, even now, as the results of the initial strike reached Artemis in less than five seconds.
One of the superdreadnoughts was obviously gone. Her wedge was down, she was streaming atmosphere and shedding debris, and the transponders of her crew's escape pods burned clear and sharp on the plot. One of her sisters was clearly in serious trouble, as well. From her impeller signature, she'd taken massive damage to her forward ring, and her emission signature showed heavy damage to the active sensors necessary for effective close-ranged missile-defense. The third superdreadnought appeared to have gotten off more lightly, but even she showed evidence of significant damage, and a second, equally massive attack wave was already tearing down on her.
