"Finally, and most important, our physicists and theoreticians are not able to extrapolate, from the analysis of our screen, to the concepts underlying the Masters' ultimate weapons of offense, the first-stage booster and its final end-product, the Vang. If, as we can safely assume, the Stretts do not already have those weapons, they will know nothing about them until we ourselves use them in battle. "These are, of course, only the principal points covered. Does anyone wish to amend this summation as recorded?" * * * * * No one did. The meeting was adjourned. Hilton, however, accompanied Sawtelle and Kedy to the captain's office. "So you see, Skipper, we got troubles," he said. "If we don't use those boosters against their skeletons it'll boil down to a stalemate lasting God only knows how long. It will be a war of attrition, outcome dependent on which side can build the most and biggest and strongest ships the fastest. On the other hand, if we _do_ use 'em on defense here, they'll analyze 'em and have everything worked out in a day or so. The first thing they'll do is beef up their planetary defenses to match. That way, we'd blow all their ships out of space, probably easily enough, but Strett itself will be just as safe as though it were in God's left-hand hip pocket. So what's the answer?" "It isn't that simple, Jarve," Sawtelle said. "Let's hear from you, Kedy." "Thank you, sir. There is an optimum mass, a point of maximum efficiency of firepower as balanced against loss of maneuverability, for any craft designed for attack," Kedy thought, in his most professional manner. "We assume that the Stretts know that as well as we do. No such limitation applies to strictly defensive structures, but both the Strett craft and ours must be designed for attack. We have built and are building many hundreds of thousands of ships of that type. So, undoubtedly, are the Stretts. Ship for ship, they will be pretty well matched. Therefore one part of my strategy will be for two of our ships to engage simultaneously one of theirs. There is a distinct probability that we will have enough advantage in speed of control to make that tactic operable." "But there's another that we won't," Sawtelle objected. "And maybe they can build more ships than we can." "Another point is that they may build, in addition to their big stuff, a lot of small, ultra-fast ones," Hilton put in. "Suicide jobs--crash and detonate--simply super-missiles. How sure are you that you can stop such missiles with ordinary beams?" "Not at all, sir. Some of them would of course reach and destroy some of our ships. Which brings up the second part of my strategy. For each one of the heavies, we are building many small ships of the type you just called 'super-missiles'."
