CHAPTER 15
DEEP SPACE PROBE
Two days later, Repulse was joined by Renown and Remarkable in orbit around Ganymede near Jupiter Station. The 160,000 ton ships were 1880 feet long and 330 feet wide.
The battle cruisers carried powerful multi-warhead anti-ship missiles, called Hydra-IIIs. Each Hydra-III was armed with six W762 warheads, with yields of seventeen megatons TNT equivalent per warhead. This guided missile was designed for use against capital spaceships. It used a combination of inertial guidance and radar homing. Additionally, it used multi-radiation detection homing devices and external laser painting. It was capable of conducting autonomous targeting with onboard targeting systems that independently acquired targets using artificial intelligence with disk memory, which used radiation-resistant semiconductor RAM and enhanced capability to make positive target identification. It was capable of making precision attacks on moving ships in extremely hostile environmental conditions. The missile was designed with penetration aids and advanced counter-countermeasures such as chaff and decoys to effectively evade hostile active defense systems.
The Hydra-III was twenty-six feet long with a four foot diameter. Fully loaded and armed, it weighed twenty eight tons. Its power plant consisted of multiple miniature anti-proton nuclear fission booster engines capable of 0.1c. It had a titanium honeycomb fuselage. It could detect and track spacecraft and small high-speed meteorites at great distances with unprecedented accuracy. It was designed to be reloaded rapidly.
The battle cruisers' engineering spaces housed nuclear reactors to generate the ships' electricity and antiproton-induced fission propulsion engines. After returning from their extended journey, Renown and Remarkable required refueling. The uranium and antiproton fuel supplies were transported from the accelerator facility on Ganymede to Jupiter Station. As the new ships arrived, each battle cruiser docked and topped off their antimatter supplies.
This flurry of refueling activity was the main topic of conversation in the midshipmen’s common room. Most of the midshipmen were either sitting at the main table, or studying in a corner desk. They were dressed casually for the most part, though there were a few in uniform preparing to go on watch. The clamor of small conversing groups filled the room. Many were using virtual display consoles to call up information and data to support their points of view.
Gallant spoke loudly so as to be heard over the din, “Refueling could be the reason for the threat of attack.”
Seated directly across from Gallant was Neumann, in full uniform. He folded his arms and scowled. The other midshipmen stared at Gallant for a moment. With the exceptions of Red and Kelsey, few of them had spoken to Gallant, outside of profession requirements, since his first day reporting aboard. Since then, Gallant had performed well enough to avoid any direct censure from his shipmates. Neumann however, never tired of challenging him whenever possible. A strong sense of rivalry had developed and they had become wary of each other.
Neumann was the son of rich and powerful Gerald Neumann, president of NNR Shipping and Mining Co. He had been the star quarterback on the academy football team and was fond of saying, “Winners always win.” And he seemed intent on proving it, every day. Now he managed to wear an expression of boredom, even though he was sitting with a posture of inflexible attention. His gaze was stuck in a distant stare.
For the most part, Gallant had learned to disappear into himself when those around him ignored him. But on this occasion, his latest comment was proving too provocative for his shipmates to simply ignore.
“What does that mean?” asked Barrington unable to contain her curiosity.
Neumann seemed to chafe in his seat, as if to protest this violation of Gallant's informal verbal isolation.
“That Titan scout we chased off several weeks ago might have discovered our newly finished accelerator on Ganymede. The aliens might realize that it will allow us to produce our own antimatter locally. That greatly extends our refueling capabilities at Jupiter Station. We now have the capability to conduct extended multiple ship journeys outward toward Saturn and Neptune. They would see that as a threat,” said Gallant.
“That is only a possibility if you think the aliens have considerable knowledge of us, as well as our ship and engine characteristics,” countered Neumann, unable to resist challenging Gallant.
“I think it’s possible that the aliens have been in our solar system for a considerable time. They could have been monitoring human progress for many decades. We know they have a sizeable population and numerous ships on Saturn's satellites,” said Gallant, standing up, leaning forward, and placing his hands on the table for emphasis.
“If that's accurate, and if they were always as hostile to us, as they appear to be now, why haven’t they attacked in force long ago?” asked Neumann.
“Perhaps, they had only a small space force until recently,” said Gallant.
“Why would that be the case?” demanded Neumann.
“Maybe they were slow to build up a fleet. Or maybe they’re originally from another star. In that case, they would have had to first build shipyards and support facilities.”
“Why couldn’t they use the interstellar ships you imagine them to have?” Neumann spoke heatedly, as he stood up and leaned forward, so that he was almost in Gallant’s face.
“We have no idea what their interstellar ships would look like. Possibly their interstellar ships would be mostly engine and life-support, particularly if they could only travel at a small fraction of the speed of light. The journey from another star might have taken many decades to get here,” said Gallant.
“Decades? You can’t be serious,” said Barrington.
Thinking out loud, Gallant said, “The UP could build a generation ship today. It would have to be self-sustaining, providing its own energy, food, air, and water. It would need to be about twice the size of the Repulse without any weapons and with a crew of just a few hundred. If we used multiple sets of engines it could continue to accelerate to nearly our current maximum missile speed of 0.1c. That would make the trip to Alpha Centauri in twenty-four years. The original crews would grow old and some would die leaving their descendants to continue the voyage.”
He could see his words were carrying weight. Gallant was thrilled that they were including him in the discussion. He added, “If the Titans started out on a generation ship from one of our neighboring stars, their original intent could have been just to provide the seeds for a colony of their species. Once they got to our solar system however, they discovered it was already inhabited.”
“If they are the more advanced species, why are they so hostile to us? They’ve never tried to communicate with us in anyway,” Chui interjected.
“If they reached the solar system a long time ago, they could have witnessed our Earth conflicts, followed by our space wars before the Unification. All in all, they wouldn’t have formed a very favorable opinion of us,” said Gallant.
“Why isn’t their technology more advanced?” someone shouted from the back.
“Possibly they had to retool and rearm. It must have taken a great deal of time to build up an infrastructure to support both their growing population and industrial base. All the while they would have kept tabs on humanity,” said Gallant.
“All their interactions with us have been hostile. Maybe they are just an aggressive and dangerous species,” said Neumann.
While he wanted to contribute his insights, Gallant didn’t want to say anything that might alienate his shipmates once more. He said, “I can’t argue with that. There’s no way for us to demonstrate friendship now, if they shoot whenever we get near.”
After a brief silence, Kelsey asked “Does anyone have an idea for what kind of fleet tactics they’ll employ?” Since Kelsey was the CIC analyst officer, she had worked with the available alien information trying to make sense of their tactics. “Everything I’ve seen makes me wonder how much AI capabilities they possess. For all we know, their entire ship could be automated. All their mane
uvers have been incredibly precise.”
“In the skirmishes that have occurred so far, never more than a few ships were involved. The aliens have been content to fire a few warning shots and leave,” said Red. “Their ships have all been destroyer, or cruiser size. We've never seen them deploy any fighters.”
“What would they do in fleet formations? Will they act as independent units, or will they act in highly coordinated fashion?” asked Chui.
“Besides worrying about formation tactics, we need to understand how they react to causalities. For example, would they use suicide attacks?” asked Barrington.
“Tell me Gallant, do you think our fighters could defeat their small destroyer size ships, one on one?” asked Neumann.
“A single fighter would be out-matched by a Titan destroyer. The destroyer could fire ship-killer missiles and heavy plasma weapons. Our lasers and antimissile missiles don’t pack enough punch to inflict more than moderate damage. Given that our fighters are five times faster than their destroyers, a fighter squadron could coordinate antimissiles to knock out their missiles while strafing them with lasers. They might even use some antimissiles to impact vital areas of the ship. That at least would be worth attempting,” responded Gallant.
The group seemed thoughtful and remained quiet for some time. Gallant’s entire experience with this discussion was very different from the dialogue he had observed during the videoconference of the battle cruisers’ captains. It seemed that the two groups addressed completely different topics, reflecting dissimilar priorities. It was possible that the captains were more concerned with higher level issues of general warfare strategy while the midshipmen were focused on the specifics of tactics in combat and the nature of the enemy.
Gallant was satisfied that this interaction had resulted in his achieving a new relationship with his shipmates. He felt that he would no longer be shunned by them, with the possible exception of Neumann and his shadow, Chui.
Still, the alien problems, both strategic and tactical, remained daunting. They didn’t have enough information to connect all the dots. What kind of creatures were they? How advanced were they? How many ships did they have? Each a great questions, but Gallant didn’t have a worthy answer. Neither did anyone else. Nevertheless he knew they would soon find out—one way or the other.
