Interesting passages in the book. Spoilers ahoy:
Military Matters:
Command always said it didn't matter which unit you got. TIE fighters were all the same, down to the last nut and bolt, but even so, every pilot had his or her favorite ship. You weren't supposed to personalize them, of course...
- Imperial TIE fighters are completely standardized.
The Empire was determined to erase all signs of individuality in its pilots, on the absurd theory that nameless, faceless operators were somehow more effective. Thus the classification numbers, the anonymous flight suits and helmets, and the random rotation of spacecraft. The standardizing approach had worked reasonably well in the Clone Wars, but there was one important difference here: neither Vil nor any of the other TIE pilots he knew of was a clone.
- Self-explanatory. It seems to be implied that all the clone pilots are gone by the time of
A New Hope.
IMSLO stood for "Imperial Military Stop Loss Order." Too many skilled people who'd been drafted had had enough of the military after the Clone Wars, and when their compulsory service ended, wanted nothing more than to go home. With the action against the Rebels heating up, the Empire couldn't allow that. Doctors, in particular, were in short supply; hence, IMSLO. A retroactive order mandating that, no matter when you'd been conscripted, you were in for as long as they wanted you - or until you got killed. Either way, it was kiss your planned life goodbye.
- Self-explanatory
If you took a guard hostage and tried to use him or her or it for leverage, it got you and the guard and anybody within a hundred meters turned into a smoking crater. No negotiation, no compromise, just a big, sleek thermal bomb arcing out of the compound and onto your position. You couldn't hide, because the bomb zeroed in on the guard's implant, which couldn't be turned off or destroyed unless you knew exactly where it was, and that location was different for every guard on the planet.
- An interesting description of a "smart bomb", of sorts.
Only a few dozen Givins had been conscripted, but their ability to survive for short periods, unsuited, in hard vacuum, even more than their aptitude for juggling integers, had resulted in more favored treatment than most other nonhumanoids got from the Empire.
- Apparently, species-related bias doesn't apply to those species with super-human abilities.
Technical Issues:
Lemelisk had disappointed him in that instance. The greatest challenge in designing the battle station, he had said, was not creating a beam cannon big enough to destroy a planet, nor was it building a moon-sized station that would be driven by a Class Three hyperdrive. The greatest challenge was powering both of them. There must be trade-offs, he had said. In order to mount a weapon of mundicidal means, shielding capabilities would have to be downgraded to a rudimentary level. Power, Bevel said, was not infinite, not even on a station this size, fueled by the largest hypermatter reactor ever built. However, given the surface-to-vacuum defenses, the number of fighters, turbolaser batteries, charged-particle blasters, magnetic railguns, proton torpedo banks, ion cannons, and a host of other protective devices, no naval ship of any size would be even a remote thread.
- Self-explanatory.
Spice smuggling by itself usually wasn't enough to rate a trip to the prison planet for a life sentence, but Balahteez had been involved in an unfortunate accident while being pursued by an Imperial patrol near the Zharan moon Gall. Realizing that his ship would soon be overtaken by the navy gunboat chasing him, Balahteez had jettisoned his illegal cargo. The drug, packed securely in a block of carbonite the size of a luggage trunk, had hurtled down Gall's gravity well and punched a large hole in the outer hull of a barracks housing a large unit of TIE fighter mechanics. The hole was big enough that thirty of the hapless mechanics had been blown through it and into vacuum by the explosive decompression, and a dozen more had run out of air before the emergency and repair droids could reseal the compartment. Not to mention the other fifty or so who had died immediately from the impact; the carbonite block had been traveling at about two kilometers a second and had left a crater thirty meters in diameter.
- Can anybody calc this?
"... Beams of coherent particles, such as electrons, positrons, and the like, as well as amplified photon emissions, are often focused with large magnetic rings. Let us postulate that one could, in this fashion, generate a weaponized beam with enough force to blow a large asteroid apart with a single blast."
"Is there such a thing?"
"In theory, yes, though it requires a power source so large as to be impractical to perambulate, even on a Star Destroyer. But," Balahteez continued, raising one phalange in emphasis, "aboard something the size of, say, a small moon, one could easily install and house such a mechanism."
- This quote will no doubt prove controversial, although, again, it's quite hard to say what by 'large asteroid' is meant in this context, especially when Balahteez goes to to say...
Let us say, for the sake of argument, that the battle station under construction is large enough to hold, oh, six or eight such weapons, as well as a hypermatter reactor that could power a small planet. And that it is possible to focus all of this energy into a single beam - by the largest and most powerful magnetic ring every made."
Here it is obvious that he speaks of the Death Star's tributary beams, and consequentially by 'large asteroid' must mean something dozens or hundreds of kilometers in diameter.
Politics:
As the commander of such a vessel, he would, perforce, be the most powerful man in the galaxy. The thought had certainly occurred to him that not even the Emperor could stand before him, did he choose to challenge Palpatine's rule. Then again, Tarkin knew the Emperor. If their positions were reversed, he knew that there was no possible way he would sanction anyone having such power - not without some kind of fail-safe.
- Self-explanatory.
Vader, unfortunately, was beyond Tarkin's command...
- A clarification of their relationship.
Her "crime" had been simply to back the wrong political candidate on a planetwide election on her world. The Emperor had decided that the man running for office was a traitor, as were his most influential supporters. He had thus ordered a score of well-to-do Mirialans to be rounded up, given a speedy "trial," and convicted of treason. Given the public outrage over this travesty of justice, it had been deemed politically expedient to execute them then and there, and so Teela and her compatriots had been shipped off to die on a world many light-years away.
- Apparently the Emperor isn't as secluded in this time period as we might have thought if he himself ordered this trial.
Vader felt a small ember of satisfaction glow within him. He had known for some time that the malcontents were growing both in organization and power. They had staged guerrilla raids on space stations and supply depots, had managed to obtain military matériel and warcraft from sympathetic industrial and shipyard designers, and had allied themselves with many alien species, playing upon the latters' resentment at being reduced to inferior status in the eyes of the New Order. They were more than just a motley collection of wild-eyed idealists; they now numbered among their ranks former Imperial strategists, programmers, and technicians, and their network of spies was growing more intricate daily. They were scum, true enough, but enough scum could clog any system, even one as complex and pristine as the Empire.
- Even as early as
A New Hope the Rebellion was more advanced than many Trekkies like to portray them. This is doubly enlightening coming from Lord Vader himself.
The Death Star:
It had been nearly three decades since Raith Sienar had first made Tarkin privy to the concept of the "battle station planetoid," and it had taken almost a decade to get the idea through the snarls of red tape and bring the Geonosians on board to improve and implement the designs. The project had been known by various code names - such as the Great Weapon - and the original plans had been much improved by the Geonosian leader Poggle the Lesser. But it had taken years for the concept to be stewarded through the torturous maze of government bureaucracy before construction was finally ordered to begin. There were still flaws in the original plan, but many of them had been addressed during the building of the proof-of-concept prototype in the Maw Installation, and others were being corrected as they were uncovered. The greatest minds in the galaxy had been recruited or drafted to lend their expertise to the building of the ultimate weapon. The brilliant Dr. Ohran Keldor, the mad weapons master Umak Leth, the young but nevertheless laser-sharp Omwati prodigy Qwi Xux, the Twi'lek administrator Tol Sivron - they, and many others of the like stripe, had been investigated and approved by Tarkin himself.
- The history of the Death Star
It wasn't even a complete skeleton yet. When done, however, the battle station would be 160 kilometers in diameter.
- New canonical size for the Death Star.
... the station would mount a complement of craft, both station and ground, equal to a large planetside base: four capital ships, a hundred TIE/In starfighters, plus assault shuttles, blastboats, drop ships, support craft, and land vehicles, all ultimately totaling in the tens of thousands. It would have an operational crew numbering more than a quarter million, including nearly sixty thousand gunners alone. The vessel could easily transport more than half a million fully outfitted troops, and the support craft - pilots, crew, and other workers - would be half that number. The logistics of it all were staggering.
- The Death Star's complement.
On a project this size there was no way to complete the entire hull, pressurize it all, and then start building the interior - the amount of air necessary wold be tremendous. Once the vessel was functional, then the multitude of converters installed in every sector could easily handle the task, but until those were online, air would have to be sucked from a planetary atmosphere and hauled up out of the gravity well by cargo ship - either that, or build a huge conversion plant in space and truck water to that, which would be even harder. A tanker full of water was more unwieldy than one full of air bottles, and without proper heat it just turned into blocks of ice when you unloaded it, which in turn resulted in problems with increased volume. The sheer magnitude of the project wouldn't allow a full exterior hull construction first.
Thus it had been reasoned early on that, while the hull was being laid, individual sectors would be built and sealed...
The hull-plate extruders were only a few hundred kilometers away, hung at a fixed orbital point where the gravitational forces of the prison planet and the raw-material asteroids being towed to the gigantic masticators all balanced. The process was simple enough. An asteroid sufficiently high in nickel-iron content was hauled from the outlying belt to the masticators and fed into a maw; the whirling durasteel teeth chewed the asteroids into tiny bits and mixed them with alloy ores mined and brought up from Despayre, including quadanium. The resulting gravel had water added and was put under high pressure to form a slurry, then fed into pipelines that led to the smelters. These were essentially huge melting pots that refined the mix, burning off impurities. The resulting scarified ore was conveyed to extruders that pressed out the hull plate, rather like food paste from a squeezed tube. There was still a lot of slag left over, but this was just gathered together, pointed at the local star, and given a hard push. Months later, these slag-rafts would fall into the sun and be burnt up.
- the Death Star's construction.
It was hard to visualize the scope of the whole orb. Big didn't do it justice. The habitable crust alone was two kilometers thick, and included in it the surface city sprawls, armory, hangar bays, command center, technical areas, and living quarters. Below that would be the hyperdrive, reactor core, and secondary power sources.
- the station's layout.
Miscellaneous:
The Rebels were turning out to be more troublesome than many had expected. The Emperor had known it would be thus, of course; the resistance had not been a surprise to him. The Emperor was completely in concert with the dark side of the Force. He was the most powerful Sith who had ever existed.
As would Vader be, someday.
- Confirmation from Lord Vader himself as to the Emperor's status.
"ADO," Vil said as he approached. "What's flyin'?"
"You and your squad, among nine others," the AOD said. He kept waving at the still-approaching pilots, down now only to a handful. "VIP escort for the Imperial-class Destroyer Devastator."
Vil blinked. "We got a rainbow-jacket admiral? A Moff?"
"Not exactly. The guy running this ship is more of a monotone," said the ADO. Noting Vil's blank look, he added, "All black."
Vil got it then. "Darth Vader?"
"Friend of yours?"
- Interestingly, it appears that Vader isn't as well-known among the rank-and-file as I had originally imagined.
With a spy-killer installed, Brun didn't need to worry much about Ratua ratting him out if he were caught. The embed unit, about the size of a baby's fingernail, would sit harmlessly in Ratua's skull for the rest of his life. But it would be tuned to a certain word, and if that word were spoken by Ratua, and only Ratua, the device would explode. Not much of an explosion - just enough to fry his brain up nice and crispy.
- A nice little device here; if a prisoner can get his hands on one, there's no reason for the Empire not to employ them.
More later.
Diocletian had the right idea.
