As I’ve mentioned before, a modern warship’s Combat Information Center — that wonderfully telegenic room full of maps, computer consoles, and sweeping polar displays of radar and sonar echos — was, according to Rear Admiral Cal Laning, taken “specifically, consciously, and directly” from the spaceship Directrix in the Lensman novels of E.E. Smith, Ph.D.
Smith introduces Directrix in the fourth novel, Grey Lensman (1951, originally published in four parts, October 1939–January 1940, Astounding Science Fiction):
He jerked back to reality as he entered the gigantic teardrop which was technically the Z9M9Z, socially the Directrix, and ordinarily GFHQ. She had been designed and built specifically to be Grand Fleet Headquarters, and nothing else. She bore no offensive armament; but since she had to protect the presiding geniuses of combat, she had every possible defense.
Port Admiral Haynes had learned a bitter lesson during the expedition to Helmuth’s base. Long before that relatively small Grand Fleet got there he was sick to the core, realizing that fifty thousand vessels simply could not be controlled or maneuvered as a group. If that base had been capable of an offensive, or even of a real defensive, or if Boskone could have put their fleets into that star cluster in time, the Patrol would have been defeated ignominiously; and Haynes, wise old tactician that he was, knew it only too well.
Therefore, immediately after the return from that “triumphant” venture, he gave orders to design and to build, at whatever cost, a flagship capable of directing efficiently a million combat units.
The “tank”—the three-dimensional galactic chart which is a necessary part of every pilot room—had grown and grown as it became evident that it must be the prime agency in Grand Fleet Operations. Finally, in this last rebuilding, the tank was seven hundred feet in diameter and eighty feet thick in the middle—over seventeen million cubic feet of space in which more than two million tiny lights crawled hither and thither in hopeless confusion. For, after the technicians and designers had put that tank into actual service, they had discovered that it was useless. No available mind had been able either to perceive any situation as a whole, or to identify with certainty any light or group of lights needing correction. And as for linking up any particular light with its individual, blanket-proof communicator in time to issue orders in space combat—
Kinnison looked at the tank, then around the full circle of the million-plug board encircling it. He observed the horde of operators, each one trying frantically to do something. Next he shut his eyes, the better to perceive everything at once, and studied the problem for an hour.
“Attention, everybody!” he thought then. “Open all circuits—do nothing at all for a while.” He then called Haynes.
“I think that we can clean up this mess if you’ll send over some Simplex analyzers and the crew of technicians. Helmuth had a sweet set-up on multiplex controls, and Jalte had some ideas that we can adapt to fit this tank. If we add them all together, we may have something.”

And by the time Worsel arrived, they did.
“Red lights are fleets already in motion,” Kinnison explained rapidly to the Velantian. “Greens are fleets still at their bases. Ambers are the planets the greens took off from—connected, you see, by Ryerson string-lights. The white star is us, the Directrix. That violet cross ‘way over there is Jalte’s planet, our first objective. The pink comets are our free planets, their tails showing their intrinsic velocities. Being so slow, they had to start long ago. The purple circle is the negasphere. It’s on its way, too. You take that side, I’ll take this. They were supposed to start from the edge of the twelfth sector. The idea was to make it a smooth, bowl-shaped sweep across the Galaxy, converging upon the objective, but each of the fleet commanders apparently wants to run this war to suit himself. Look at that guy there—he’s beating the gun by nine thousand parsecs. Watch me pin his ears back!”
He pointed his Simplex at the red light which had so offendingly sprung into being. There was a whirring click and the number 449276 flashed above a board. An operator flicked a switch.
“Grand Fleet Operations!” Kinnison snapped. “Why are you taking off without orders?”
“Why, I … I’ll give you the vice-admiral, sir—”
“No time! Tell your vice-admiral that one more such break will put him in irons. Land at once! GFO—off!”
“With around a million fleets to handle, we can’t spend much time on anyone,” he thought at Worsel, “but after we get them lined up and get our Rigellians broken in, it won’t be so bad.”
The breaking in did not take long; definite and meaningful orders flew faster and faster along the tiny, but steel-hard beams of the communicators.
“Take off…. Increase drive four point five…. Decrease drive two point seven…. Change course to—” and so it went, hour after hour and day after day.
And with the passage of time came order out of chaos. The red lights formed a gigantically sweeping, curving wall, its almost imperceptible crawl representing an actual velocity of almost one hundred parsecs an hour. Behind that wall blazed a sea of amber, threaded throughout with the brilliant filaments which were the Ryerson lights. Ahead of it lay a sparkling, almost solid blaze of green. Closer and closer the wall crept toward the bright white star.
And in the “reducer”—the standard, ten-foot tank in the lower well—the entire spectacle was reproduced in miniature. It was plainer there, clearer and much more readily seen; but it was so crowded that details were indistinguishable.
