But if the attacker controlled more than a single secondary terminus, he could send the same tonnage to the central nexus through each of them without worrying about transit windows, since none would use exactly the same route. Choreographing such an assault would require meticulous planning and synchronization—not an easy matter for fleets hundreds of light-years apart, however good the staff work—yet if it could be pulled off, it would allow an attack in such strength that no conceivable fortifications could stop it.

Not even Manticore’s, Honor thought as Fearless slowed to rest relative to the Junction. Even though the Junction fortresses accounted for almost thirty percent of the RMN’s budget, the security—or at least neutrality—of the Junction’s other termini simply had to be guaranteed.

“We have readiness clearance from Junction Central, Ma’am,” Lieutenant Webster announced. “Number eight for transit.”

“Thank you, Com.” She glanced at her maneuvering display as the scarlet numeral “8” appeared beside Fearless’s cursor, then turned her gaze to the duty helmsman. McKeon sat silently beside Lieutenant Venizelos at Tactical, but her eyes passed over him without even acknowledging his presence. “Put us in the outbound lane, Chief Killian.”

“Aye, aye, Ma’am. Coming to outbound heading.” Killian fell silent for a moment, then, “In the lane, Captain.”

Honor nodded her satisfaction and glanced up at the visual display just as a stupendous bulk carrier erupted from the junction. It was an incredible sight, one she never tired of, and the display’s magnification brought it to arm’s length. That ship had to mass over five million tons, yet it blinked into sight like some sort of insubstantial ghost, a soap bubble that solidified into megatons of alloy in the blink of an eye. Its huge, immaterial Warshawski sails were circular, azure mirrors, bright and brilliant for just an instant as radiant transit energy bled quickly into nothingness, and then it folded its wings. The invisible sails reconfigured into impeller stress bands, and the freighter slowly gathered way, accelerating out of the nexus while it cleared its final destination with Junction Central and requested insertion into the proper outbound lane to continue its voyage.

Fearless moved steadily forward with the other outbound vessels. In time of peace, she had no greater priority than any of the gargantuan merchantmen who dwarfed her to insignificance, and Honor leaned back in her chair to savor the bustle and purposeful energy of the Junction in action.

Under normal circumstances, the Junction handled inbound and outbound vessels at an average rate of one every three minutes, day in and day out, year after year. Freight carriers, survey vessels, passenger ships, inner-world colony transports, private couriers and mail packets, warships of friendly powers—the volume of traffic was incredible, and avoiding collisions in normal-space required unrelenting concentration by the controllers. The entire Junction was a sphere scarcely a light-second in diameter, and while that should have been plenty of space, each terminus had its own outbound and inbound vector. Transiting to the proper destination required that those vectors be adhered to very precisely indeed (especially when not even Junction Central knew exactly who might be inbound from where at any given moment), and that meant traffic was confined to extremely limited areas of the Junction’s volume.
