Three. Outside on the airless field, the amber warning lights were spinning on the Tower mast, warning the spacesuited maintenance crews away from the blast pits. Chavez was snapping orders into the intercom and the Darkside was awaking to activity smoothly. Five shielded decks below Control, Chief Jetman Collins and the black-gang were busily removing the seals from the cadmium dampers in the blast chambers. The "three-minutes-to-lift-ship" alarm blared and the lights dimmed, leaving Control lighted only by the reflected glow of the panel lights. On the visiplate screen, the slender shapes of the Lysander, the Argus and the fat, ungainly silhouette of the ironically named Artemis showed clearly in the earthlight. The Artemis, thought Hartnett, was the only weak link in his command. The other three ships were modern, but the Artemis was an ancient alcohol burner, converted to atomics and pressed into service by the exigencies of an undeclared and treacherous war. At best, she could stand no more than 5 Terran Gs and the rest of the Flotilla would be forced to keep to her reduced speed throughout the cruise. Her armament was lighter and her armor thinner than it should be. In fact, she was strictly Cat meat if she should ever be forced to stand and fight. And if they intercepted any Cats, that is exactly what she would have to do, since she was the only ship of Blue Three that could not outrun any comparable Martian ship. Scott was giving his orders now, eyes fastened on the master chronometer. Hartnett was pleased to see that he did so without a sidelong look at his superior. He knew his business and did it. Good. Then Hartnett could stick to handling Blue Three and worrying about the Artemis without thought of how the ship under him was being managed. He slipped into his G-Suit and plugged the lines into an outlet on the side of his chair. The second hand swept up the face of the dial, and Scott hit the firing studs. Far below, Jetman Collins removed the dampers from the main blast chambers. The takeoff was strictly routine for the Luna Base personnel. The four ships of the Flotilla rose from the pits on their long tails of radioactive flame, setting the outside Geiger counters to clucking wildly and outlining in vivid relief the three dreadnaughts that lay in their careening berths and the dozen or so smaller ships on the line. Under 3 Terran Gs of acceleration, Flotilla Blue Three was soon lost in the ebony sky. For just an instant there was the vaguest
