Triplanetary Part 13

"I'll say it is! O.K., Ted, squeeze in here!"

He squeezed in. It was not a ball, but a hemisphere, slightly oblate and centered approximately by the North Pole. A mult.i.tude of red dots moved slowly-a hundred miles upon that map was a small distance-northward over Canada; a closer-packed, less numerous group of yellowish-greens, already on the American side of the Pole, was coming south.

As had been expected, the Americans had more missiles than did the enemy. The other belief, that America had more adequate defenses and better-trained, more highly skilled defenders, would soon be put to test.

A string of blue lights blazed across the continent, from Nome through Skagway and Wallaston and Churchill and Kaniapiskau to Belle Isle; America's First Line of Defense. Regulars all. Ambers almost blanketed those blues; their combat rockets were already grabbing alt.i.tude. The Second Line, from Portland, Seattle, and Vancouver across to Halifax, also showed solid green, with some flashes of amber. Part Regulars; part National Guard.

Chicago was in the Third Line, all National Guard, extending from San Francisco to New York. Green-alert and operating. So were the Fourth, the Fifth, and the Sixth. Operation Bullfinch was clicking; on schedule to the second.

A bell clanged; the men sprang to their stations and strapped down. Every chair was occupied. Combat Rocket Number One Oh Six Eight Five, full-powered by the disintegrating nuclei of unstable isotopes, took off with a whoos.h.i.+ng roar which even her thick walls could not mute.

The Technos, crushed down into their form-fitting cus.h.i.+ons by three G's of acceleration, clenched their teeth and took it.

Higher! Faster! The rocket s.h.i.+vered and trembled as it hit the wall at the velocity of sound, but it did not pause.

Higher! Faster! Higher! Fifty miles high. One hundred ... five hundred ... a thousand ... fifteen hundred ... two thousand! Half a radius-the designated alt.i.tude at which the Chicago Contingent would go into action.

Acceleration was cut to zero. The Technos, breathing deeply in relief, donned peculiarly-goggled helmets and set up their panels.

Kinnison stared into his plate with everything he could put into his optic nerve. This was not like the Ball, in which the lights were electronically placed, automatically controlled, clear, sharp, and steady. This was radar. A radar considerably different from that of 1948, of course, and greatly improved, but still pitifully inadequate in dealing with objects separated by hundreds of miles and traveling at velocities of thousands of miles per hour!

Nor was this like the practice cruises, in which the targets had been harmless barrels or equally harmless dirigible rockets. This was the real thing; the targets today would be lethal objects indeed. Practice gunnery, with only a place in the Proficiency List at stake, had been exciting enough: this was too exciting-much too exciting-for the keenness of brain and the quickness and steadiness of eye and of hand so soon to be required.

A target? Or was it? Yes-three or four of them!

"Target One-Zone Ten," a quiet voice spoke into Kinnison's ear and one of the white specks upon his plate turned yellowish green. The same words, the same lights, were heard and seen by the eleven other Technos of Sector A, of which Kinnison, by virtue of standing at the top of his Combat Rocket's Proficiency List, was Sector Chief. He knew that the voice was that of Sector A's Fire Control Officer, whose duty it was to determine, from courses, velocities, and all other data to be had from ground and lofty observers, the order in which his Sector's targets should be eliminated. And Sector A, an imaginary but sharply-defined cone, was in normal maneuvering the hottest part of the sky. Fire Control's "Zone Ten" had informed him that the object was at extreme range and hence there would be plenty of time. Nevertheless:

"Lawrence-two! Doyle-one! Drummond-stand by with three!" he snapped, at the first word.

In the instant of hearing his name each Techno stabbed down a series of studs and there flowed into his ears a rapid stream of figures-the up-to-the-second data from every point of observation as to every element of motion of his target. He punched the figures into his calculator, which would correct automatically for the motion of his own vessel-glanced once at the printed solution of the problem-tramped down upon a pedal once, twice, or three times, depending upon the number of projectiles he had been directed to handle.

Kinnison had ordered Lawrence, a better shot than Doyle, to launch two torpedoes; neither of which, at such long range, was expected to strike its mark. His second, however, should come close; so close that the instantaneous data sent back to both screens-and to Kinnison's-by the torpedo itself would make the target a sitting duck for Doyle, the less proficient follower.

Drummond, Kinnison's Number Three, would not launch his missiles unless Doyle missed. Nor could both Drummond and Harper, Kinnison's Number Two, be "out" at once. One of the two had to be "in" at all times, to take Kinnison's place in charge of the Sector if the Chief were ordered out. For while Kinnison could order either Harper or Drummond on target, he could not send himself. He could go out only when ordered to do so by Fire Control: Sector Chiefs were reserved for emergency use only.

"Target Two-Zone Nine," Fire Control said.

"Carney, two. French, one. Day, stand by with three!" Kinnison ordered.

"d.a.m.n it-missed!" This from Doyle. "Buck fever-no end."

"O.K., boy-that's why we're starting so soon. I'm shaking like a vibrator myself. We'll get over it...."

The point of light which represented Target One bulged slightly and went out. Drummond had connected and was back "in".

"Target Three-Zone Eight. Four-eight," Fire Control remarked.

"Target Three-Higgins and Green; Harper stand by. Four-Case and Santos: Lawrence."

After a minute or two of actual combat the Technos of Sector A began to steady down. Stand-by men were no longer required and were no longer a.s.signed.

"Target Forty-one-six," said Fire Control; and:

"Lawrence, two. Doyle, two," ordered Kinnison. This was routine enough, but in a moment:

"Ted!" Lawrence snapped. "Missed-wide-both barrels. Forty-one's dodging-manned or directed-coming like h.e.l.l-watch it, Doyle-WATCH IT!"

"Kinnison, take it!" Fire Control barked, voice now neither low nor steady, and without waiting to see whether Doyle would hit or miss. "It's in Zone Three already-collision course!"

"Harper! Take over!"

Kinnison got the data, solved the equations, launched five torpedoes at fifty gravities of acceleration. One ... two-three-four-five; the last three as close together as they could fly without setting off their proximity fuzes.

Communications and mathematics and the electronic brains of calculating machines had done all that they could do; the rest was up to human skill, to the perfection of co-ordination and the speed of reaction of human mind, nerve, and muscle.

Kinnison's glance darted from plate to panel to computer-tape to meter to galvanometer and back to plate; his left hand moved in tiny arcs the k.n.o.bs whose rotation varied the intensities of two mutually perpendicular components of his torpedoes' drives. He listened attentively to the reports of triangulating observers, now giving him data covering his own missiles, as well as the target object. The fingers of his right hand punched almost constantly the keys of his computer; he corrected almost constantly his torpedoes' course.

"Up a hair," he decided. "Left about a point."

The target moved away from its predicted path.

Down two-left three-down a hair-Right! The thing was almost through Zone Two; was blasting into Zone One.

He thought for a second that his first torp was going to connect. It almost did-only a last-instant, full-powered side thrust enabled the target to evade it. Two numbers flashed white upon his plate; his actual error, exact to the foot of distance and to the degree on the clock, measured and transmitted back to his board by instruments in his torpedo.

Working with instantaneous and exact data, and because the enemy had so little time in which to act, Kinnison's second projectile made a very near miss indeed. His third was a graze; so close that its proximity fuze functioned, detonating the cyclonite-packed war-head. Kinnison knew that his third went off, because the error-figures vanished, almost in the instant of their coming into being, as its detecting and transmitting instruments were destroyed. That one detonation might have been enough; but Kinnison had had one glimpse of his error-how small it was!-and had a fraction of a second of time. Hence Four and Five slammed home; dead center. Whatever that target had been, it was no longer a threat.

"Kinnison, in," he reported briefly to Fire Control, and took over from Harper the direction of the activities of Sector A.

The battle went on. Kinnison sent Harper and Drummond out time after time. He himself was given three more targets. The first wave of the enemy-what was left of it-pa.s.sed. Sector A went into action, again at extreme range, upon the second. Its remains, too, plunged downward and onward toward the distant ground.

The third wave was really tough. Not that it was actually any worse than the first two had been, but the CR10685 was no longer getting the data which her Technos ought to have to do a good job; and every man aboard her knew why. Some enemy stuff had got through, of course; and the observatories, both on the ground and above it-the eye of the whole American Defense-had suffered heavily.

Nevertheless, Kinnison and his fellows were not too perturbed. Such a condition was not entirely unexpected. They were now veterans; they had been tried and had not been found wanting. They had come unscathed through a bath of fire the like of which the world had never before known. Give them any kind of computation at all-or no computation at all except old CR10685's own radar and their own torps, of which they still had plenty-and they could and would take care of anything that could be thrown at them.

The third wave pa.s.sed. Targets became fewer and fewer. Action slowed down ... stopped.

The Technos, even the Sector Chiefs, knew nothing whatever of the progress of the battle as a whole. They did not know where their rocket was, or whether it was going north, east, south, or west. They knew when it was going up or down only by the "seats of their pants." They did not even know the nature of the targets they destroyed, since upon their plates all targets looked alike-small, bright, greenish-yellow spots. Hence:

"Give us the dope, Pete, if we've got a minute to spare," Kinnison begged of his Fire Control Officer. "You know more than we do-give!"

"It's coming in now," came the prompt reply. "Six of those targets that did such fancy dodging were atomics, aimed at the Lines. Five were dirigibles, with our number on 'em. You fellows did a swell job. Very little of their stuff got through-not enough, they say, to do much damage to a country as big as the U.S.A. On the other hand, they stopped scarcely any of ours-they apparently didn't have anything to compare with you Technos.

"But all h.e.l.l seems to be busting loose, all over the world. Our east and west coasts are both being attacked, they say; but are holding. Operation Daisy and Operation Fairfield are clicking, just like we did. Europe, they say, is going to h.e.l.l-everybody is taking pot-shots at everybody else. One report says that the South American nations are bombing each other ... Asia, too ... nothing definite; as straight dope comes in I'll relay it to you.

"We came through in very good shape, considering ... losses less than antic.i.p.ated, only seven percent. The First Line-as you know already-took a G.o.d-awful sh.e.l.lacking; in fact, the Churchill-Belcher section was practically wiped out, which was what lost us about all of our Observation.... We are now just about over the southern end of Hudson Bay, heading down and south to join in making a vertical Fleet Formation ... no more waves coming, but they say to expect attacks from low-flying combat rockets-there goes the alert! On your toes, fellows-but there isn't a thing on Sector A's screen...."

There wasn't. Since the CR10685 was diving downward and southward, there wouldn't be. Nevertheless, some observer aboard that rocket saw that atomic missile coming. Some Fire Control Officer yelled orders; some Technos did their best-and failed.
