They didn't have to wait long. A few minutes later, a trace appeared in the same octant of the scope where the earlier trace had vanished.
"Same ship, all right," said the FCO. "It would take them that long to turn around. They're going to try to come in for a kill."
"Signal Final Alert," said the captain.
As the buzzer sizzled out its message, Roysland flexed his muscles in a subconscious desire for action.
Captain Dobrin seemed to realize for the first time that Roysland was in the control room. His face was hard and tightly drawn, and only very slightly showed the strain that was beneath.
"We're going to operate according to the new tactics," he said. "We'll use the torpedoes first and the aJ guns last. We'll use screenbusters and files."
Roysland nodded. "You're in command here, captain. I know nothing of spatial strategy."
The prime officer turned back to the FCO. "Check maximum volume and englobe. It'll be expensive, but we can't afford to take chances now."
"Yes, sir," said the fire control officer.
Roysland watched the instruments closely as the FCO gave his orders. The first job was to feed into the calculators the exact course and velocity of the enemy ship. Then they waited until the calculators gave the most probable volume of space that the ship would occupy after the screenbuster torpedoes were sent.
