They did, but Galen misdirected them There's a supplemental document included in the Rogue One novelization, comprised of several messages sent between Galen and one of the engineering managers, where we learn that Galen's reactor modifications actually did trigger diagnostic warnings, as one would expect: I had the droids generate a new Systems Safety ...

The primary purpose of the Death Star is to create order through fear, as stated by Tarkin in A New Hope. TARKIN: The regional governors now have direct control over territories. Fear will keep the local systems in line. Fear of this battle ...

Darth Satan got it first and deserves the credit, but I couldn't resist doing this in Photoshop: I took the picture in the question, found a frame from before it where the Executor hasn't hit the station yet so I could see how long the nose is, did a proportional resizing because the resolutions weren't the same, overlaid the full Executor on the crash ...

The canon explanation is given in the novel Tarkin. The Empire used a combination of secluded and inhospitable bases which each supported only part of the project. This made sure no single person (except the Emperor and Tarkin) knew about the project as a whole. The Death Star was constructed in orbit over the planet Geonosis, and the planet's irradiated ...

This was addressed in an "Ask the Jedi Council" feature on the StarWars.com website. According to LucasFilm's (former) Head of Fan Relations/Director of Content Management Steve Sansweet, the Death Star was simply not powerful enough to destroy a gas giant. Q. In Star Wars, why does the Death Star go around the planet Yavin to blow up the fourth moon ...

War crimes are generally defined as actions taken during war time that violate agreements regarding what is and is not acceptable in war. Therefore, it's impossible to say how Luke's actions would be viewed without knowing what conventions of warfare (if any) are agreed upon in the Star Wars universe. However it seems highly unlikely that Luke's actions were ...

The shield generator was temporary protection while the second Death Star was under construction. Both Death Stars had built-in shield generators to protect against enemy capital ships but starfighters were not considered a threat in the design of the first Death Star. The first Death Star therefore had a vulnerability in an exposed thermal exhaust port ...

From the old West End Games D6 Roleplaying Game (Second Edition) supplement Death Star Technical Companion, Chapter Two: Technical Specifications, p. 16, right column: Gravity within the battle station was handled by omni-directional gravity boosters built into the decks, walls and ceilings. These gravity boosters changed orientation as easily as flipping ...

The Rebels had a slight advantage: they already knew what they were looking for; Galen's message, relayed by Jyn, explained both what to do, and what the result would be: "What kind of trap?" [Baze] asked. "You said your father made a trap.” "The reactor." On this point Jyn was utterly certain. "He's placed a weakness there. He's been hiding it for ...

According to the (canon) short story Eclipse, the inhabitants were largely in the dark about the nature of their impending demise. The "planet killer" was a closely guarded secret. A few individuals were aware of what had just arrived in orbit but it all happened far too quickly and communications was jammed so any hope of organised resistance or mass escape ...

In space, orientation is relative Unless the Death Star is very close to a planet or other massive body, any significant gravity it produces is artificial. As such, whether the laser dish is in the southern or northern hemispheres is purely a matter of camera angle. Sometimes it looks like this: Other times it looks more like this: But in either case, ...

It's always in the northern hemisphere. You're upside down. The Emperor's throne room on the second Death Star was on the top of a 100-story tower located on the north pole of the superweapon. The Emperor's throne room on the first Death Star was located in an observation dome at the top of a tower placed directly next to the station's superlaser. The ...

The shield generator on the moon of Endor was there to provide protection during the construction phase. Since the Death Star II was not complete, it wasn't yet able to generate its own shields like the original Death Star. Once construction had completed, the Death Star II could move away from the moon under its own shield protection.


57

I would like to point to the fact that when Luke is escaping with Darth Vader, the battle already took a huge step in favor of the alliance. The Shield generator on Endor was destroyed where every man inside the Death Star knew it wasn't fully defensively operational yet. The Star Destroyer crashed into the Death Star moments before. I can imagine whenever ...

According to Star Wars Technical Journal (Volume Two) (July 1994) (emphasis added): At the core of the Death Star was an immense, cavernous housing for the battle station's power generator matrix. A fusion reactor of incredible proportions, fed by stellar fuel bottles lining its periphery, produced the raw energy demanded by the Death Star's superlaser ...


55

This is directly addressed in the movie during the rebel briefing on Yavin IV (emphasis added): GOLD LEADER: Pardon me for asking, sir, but what good are snub fighters going to be against that? DODONNA: Well, the Empire doesn't consider a small one-man fighter to be any threat, or they'd have a tighter defense. An analysis of the plans provided by ...

It depends on what level of canon you are looking for. If you accept the Gaming books, the Death Star Technical Companion (at least one of them, I believe there were several) lists it as having both Ion drives and a series of 123 hyper-drive field generators. See chapter two, Technical Specifications. (Image from the Death Star Technical Companion, 1st ...

I think it was because they didn't want to wait to get into ideal position. The Death star was rising from the horizon and positioning itself to attack. Turning huge battle station like that even for few degrees may take a long time (if we take into consideration the firing at the rebels base in ANH, where they managed to deploy a whole squadron and ...

According to the new (Disney Canon) junior novel, 'Star Wars: The Princess, the Scoundrel and the Farm Boy', the Station was codenamed the Death Star; But the system had been swarming with Imperials. They’d caught on to Leia’s bogus tale about her ship’s breaking down, but the cover had helped her stall long enough to download the technical plans for ...

Have you ever worked on or seen a FMECA? Even for a simple system, they are a truly stupendous amount of work. A few years ago, I reviewed one performed by someone else on a relatively complex system (four electronics racks, plus some ancillary equipment), and reviewing it alone took about three full-time months. I don't know how long performing it took, but ...

They didn't make a microjump because Hyperdrive doesn't work in a gravity well. They probably didn't jump directly to a spot where they could target the moon immediately because they didn't know the precise location of the moon within Yavin's orbit, and they happened to come out of hyperspace on the wrong side of the planet. Besides, they were (at least ...

These calculations are approximate: 12000km diameter planet = 1.1e6 square km of debris. Death Star max range is 2000000km to 240000000km. Effective volume is 2.5e13 to 1.8e17 so around 2 parts per 1e7 to 1e11. Given the above, there is a good chance of avoiding everything, if anything got close they have plenty of time to respond. Recommended operational ...

The key concept that you are missing is proportionality. To quote Luis Moreno-Ocampo, Chief Prosecutor of the ICC, in 2006: Under international humanitarian law and the Rome Statute, the death of civilians during an armed conflict, no matter how grave and regrettable, does not in itself constitute a war crime. International humanitarian law and the ...

Having re-read the script, it seems that Tarkin and Vader didn't view the attack (by the fighters) as much more than an annoyance until it was far too late. Resistance (by the Rebels, who're about to get their base destroyed) was always to be expected but since the Death Star's armour was considered impregnable to fighters and since the Imperials were ...

It wasn’t at full power The Death Star was not being used at full power. It only blew up a portion of the moon’s surface, not the entire moon. “Target Jedha City,” he snapped. “Prepare single reactor ignition.” Krennic concealed his resentment, calmed himself with the sounds of his breath and the tidal rush of the station reactor. This wasn’t how ...

After blowing up Alderaan, the Death Star's role is Power Projection (aka Force Projection) for the Empire. See Wikipedia's article on Power projection. The Death Star was supposed to be impervious to all threats. So strategically where it goes, the Empire's at its strongest. It doesn't have to blow up any more planets. Being able to travel Faster-Than-...

They're Spacetroopers They were retconned identified as such at Celebration Anaheim 2015, and got a collectible toy release from Hot Toys; quoting from their description: The Spacetroopers are assigned to operate in Zero-G environments, and true Star Wars fans will see these troopers making their appearance when the Millennium Falcon was first captured ...

The second Death Star's construction started during the Battle of Yavin, when Emperor Palpatine ordered for the construction of new superlasers, to which the resources for its construction, including Hyperspace tugs and treadships, from its origin near Sullust to Endor via the Silvestri Trace, an obscure hyperspace route. Ironically, he issued this order ...

A New Hope does specifically state that Alderaan was the first planet destroyed by the Death Star, as mentioned by Valorum. Tarkin: Not after we demonstrate the power of this station. In a way, you have determined the choice of the planet that'll be destroyed first. Since ...
