AOTC ICS QuoteEdit

I believe the ICS stated that Base Delta Zero orders were given during the Clone Wars. Can anyone post the exact quote? JimRaynor55 00:50, 13 Jan 2006 (UTC)

"Orbital bombardments with high-yield proton torpedoes and surgical turbolaser strikes hit enemy fortifications when capture is not a priority. Armies entrenched deep underground may be subject to a last-resort "Base Delta Zero" fleet bombardment. Such operations reduce the upper crust of a planet to molten slag - a spectacle unseen in the Republic until the Clone Wars." --Vermilion 01:44, 13 Jan 2006 (UTC)
Wasn't the destruction of Taris under Base Delta Zero, LONG before the Clone Wars? User:LonnyD 15:34, 28 Jan 2006

No. The planet's surface wasn't melted. Only buildings above 3 stories high were demolished, not melted.


I agree. Taris was rubbled, but not turned to glass (as Canderous likes to do oh so much.) Although, the falling debris from kilometers of city falling on you would probably smush the outcasts pretty well... And that also reminds me, it seems like BDZ's were done during the Mandalorian Wars, because Canderous says "What's a few continents turned to glass, if you have the whole world in the end?" That would also seem to show that a BDZ does not necessarily cook the ENTIRE planet, for instance, you could fry the continent that has the most military and resistance stuff, and keep the resources for yourself.

Also, I don't think that Ralltiir was base delta zeroed. Bombed, yes, but I always thought it was brutally subjugated by the Empire, not eradicated. Melting the crust of a planet to a uniform glassy surface makes it kind of useless to "liberate" later on, too. --Commander Mike 04:23, 4 May 2006 (UTC)

Mustafar wasn't BDZed either. An orbital strike against a facility != BDZ. --SWVRoma

  • How comes Gerrard V and Jabiim are in the list? If the BDZ is really reducing the whole surface to a depth of few km to slag, you'd expect that civilization would cease to exist. Yet, in the case of Jabiim, there were survivors-turned-slaves by the Empire; And Gerrard V had some civilization around or shortly after the Battle of Yavin (see: Rogue Squadron, the Liberation of Gerrard V) -Challenger STA 14:56, 17 July 2006 (UTC)
    • I took out Jabiim and Gerrard V from the list as I cannot see any evidence that it was an actual Base Delta Zero - the planets were still habitable after all. They still are in the source code of the site, so if anyone can prove it is a full fledged BDZ to be mentioned here, put it back.. but not before that, please. :) -Challenger STA 14:12, 18 July 2006 (UTC)

New Republic Use? Edit

Can't remember the exact battle, but it was the one in the Yuzhan Vong war where the remaining senators told the the base there to hold the planet. They set up a zone around the perimeter of the base, and when Vong ground forces crossed into it, they bombarded the zone from orbit with Star Destroyers. -- 02:05, 9 September 2006 (UTC)

That's not a Base Delta Zero. A BDZ operation deliberately tries to wipe out EVERYTHING on the planet's surface, by melting the whole crust to a depth of several kilometers. JimRaynor55 18:53, 10 September 2006 (UTC)

Fanon belief? Edit

The AOTC: ICS states that a BDZ could reduce the upper crust of a planet to molten slag.--Lord OblivionSith holocronSith Emblem 16:46, 9 December 2006 (UTC)

  • It does does not indicate that it reduces the entire crust of a planet to molten slag, could simply be a small area of the upper crust at any one time...of course if they kept bombarding it, then it would all be reduced...but it's not necessarily what happens every time. —Jaymach Ral'Tir (talk) 16:48, 9 December 2006 (UTC)
    • Oh, I see.--Lord OblivionSith holocronSith Emblem 16:49, 9 December 2006 (UTC)
    • Since the operation that was to be carried out on Nar Shaddaa in The Hutt Gambit was described as a BDZ as well, and the commanding officer expected to search through ruined cityscape afterwards, this means there are several degrees of destruction available to the commander in charge (not surprising, since turbolasers have variable yields). Some BDZs only destroy assets on the surface across the entire planet, while the more severe bombardments like the ones described in AOTC:ICS, go further down into the target world. Either way the entire planet is devastated. That is the goal of a BDZ and why it is used only as a last resort. VT-16 22:10, 9 December 2006 (UTC)
      • In that case, the note from Galaxy Guide 9: Fragments from the Rim describing the First Sun Mobile Regiment as a unit which "often undertakes missions with the same objective as the Empire's 'Base Delta Zero' command" should be taken into account: a regiment of repulsorlift infantry couldn't melt a planet's crust, but they could certainly level a medium-sized settlement. —Silly Dan (talk) 15:48, 10 December 2006 (UTC)
        • Then it will be added. VT-16 19:07, 11 December 2006 (UTC)
  • A few more questions/thoughts...
  • Is BDZ always a planet-wide operation? The initial description in The Imperial Sourcebook just describes surface targets which the Army hasn't been able to overrun, while AotC:ICS describes "Armies entrenched deep underground" as potential targets. The most explicit evidence for planetary scale comes from Han's POV in The Hutt Gambit, thinking of BDZ as an order that called for the decimation of a world. I'm not convinced that this overrides the other evidence, which is why my edit of the page said that a BDZ "typically" laid waste to an entire planet. [1]
  • Does a BDZ neccessarily involve "either reducing the upper crust of a planet to molten slag or atomizing the planet's top-soil"? This claim is widespread in fandom (indeed, I believed it myself until a few weeks ago) but I know of no canon evidence showing either of these phenomena as a neccessary component of a BDZ. Nowhere is planet-wide crust-slagging ever directly linked with a BDZ; the "dense clouds of atomised topsoil" at Dankayo don't have to represent all of it; and the plan at Nar Shaddaa called for the bombardment of a cityscape, which entails neither alternative. Similarly, the First Sun's operations probably involve neither either; while local in scale, they nevertheless achieve "the same objective as the Empire's 'Base Delta Zero' command".
  • Following on from both of these questions, there's the general question of whether planet-wide crust-slagging is ever actually described in Star Wars canon. This can be considered in three parts:
  1. Pre-ICS statements that an ISD "has enough firepower to reduce a civilization to slag" (The Star Wars Sourcebook), "has enough firepower to reduce a civilized world to slag" (The Imperial Sourcebook), or "can reduce a planet surface to smoking debris in a matter of hours" (Star Wars Technical Journal). None of these explicitly describe the melting of a planet's crust, merely the reduction of a "civilized" world to rubble.
  2. Simple Euclidian geometry. As I said on the version of the page I edited, to complete the bombardment of an Earth-sized world in a 24-hour period would require a continuous rate of fire affecting nearly six thousand square kilometers every second. For a single ISD with, depending on how you interpret it, either twenty or six of its heaviest guns able to bear on a single target, that seems like an implausible area per shot (XX-9 turbolasers are also said to have a rate of fire of one shot every two seconds; that's 600 km² per shot, or 1,000 km² per barrel per second if you think the turret guns are something different and bigger).
  3. ICS statements. As already mentioned, when Attack of the Clones: Incredible Cross-Sections says that "Such operations reduce the upper crust of a planet to molten slag", it's with reference to BDZs being mounted against "Armies entrenched deep underground", and needn't indicate planet-wide crust-melting. Revenge of the Sith: Incredible Cross-Sections mentions "The hour-long orbital bombardment that depopulated and melted the crust of the former city world of Humbarine". This solitary reference is probably the nearest thing we have to a statement of planet-wide crust-melting, but it doesn't quite say that all of Humbarine's crust was melted, or to what depth, and I'm not entirely sure how it fits with the rest of the evidence. We don't quite know what sort of firepower the Separatists brought to this attack, and we also don't know exactly what the mechanism of the destruction was: it doesn't have to have been a simple case of turbolaser impacts.
  4. For what its worth, Coruscant and the Core Worlds describes the bombardment of Caamas without reference to crust-melting: a "firestorm decimated all vegetation and animals and most of the sentient Caamasi", leading to ecological and climatological collapse: a lack of plant-life to convert oxygen or provide food killed off surviving animals, and "Immense clouds of soot and smoke" rendered the atmosphere toxic to most sentients. The lack of vegetation led to widespread erosion and dust-storms, and "even the oceans have become polluted from run-off".
  5. We can also observe that Knight Hammer is ineffectual in its bombardment of Yavin 4 in Darksaber, and Lusankya takes four minutes to wipe out a Yuuzhan Vong armoured battlegroup on the surface of Borleias in Allston's duology. These depictions of Super Star Destroyers don't really support the idea that an Imperial-class Star Destroyer can reduce thousands of square kilometers of planetary surface to molten slag every second.
  • Thoughts? --McEwok 21:23, 17 December 2006 (UTC)
    •  ::#Point 1 explicitly says they can reduce a civilization to slag, when you are then claiming means it can't.
  1. Point 2 is counted by the fact that we see a heavier rate of fire in the films and the fact that the ability to perform the operation is dependent on the power input. You are arbitrarily claiming that the guns lack sufficient power when the heavy guns have never had a published yield
  2. Point 3 is countered by the picture, which clearly shows a Victory blasting a planet to the point where it is glowing molten orange
  3. Those bombardments took place with the attackers own ground forces in the area, obviously they aren't going to try and kill them. Not all orbital bombardments are BDZs

For one there could be several reasons for the trouble of the NR Super Star Destroyer's bombardment on Borleias to not have been effective. 1.Large area's of Executor without weapons: 1900000 meters long with only 4250 weapons capable of bombardment. thats about if you space them evenly apart 447 meters between them. 2. New Republic Always afraid of Civilian losses (Unlike GE) thus that could've hindered them 3. New Republic Gunners not adept at Orbital bombardment operations (Since they nearly never did them or had any evidence showing any preparation of doing any) For the Knight Hammer It was possible that the Knight Hammer didn't have specific targeting data to destroy the Temple and It wasn't a DBZ merely an orbital bombardment which denotes smaller amounts of firepower used (Unknown why but Orbital Bombardment and DBZ Operations are different in the amount of firepower used and the precision of attacks)--User:MarcusDarkstar

I believe it was said that 3 Star Destroyers could reduce the CIVILISED surface of a world would to slag in a matter of hours. On a world like Coruscant, that could encompass virtually the entire surface of the planet (though that may require more than 3 ships) but more sparsely developed worlds wouldn't require the same level of destruction.

Mandalorian BDZ Edit

would The Nuking of Serroco Count as a Base Delta Zero Operation? Or Jebble? Or Does BDZ only count when used by republic or Sith Imperials? Unsigned comment by (talk • contribs).

BDZ in Rebels Edit

In the new SW Rebels episode, a holonet broadcast mentioned "another planet liberated as per the Base Delta Zero Initiative." BDZ is canon again!!!

-- 02:41, October 27, 2014 (UTC) Dragon

Well, and does the meaning of this order remained the same? Since it make no sense in referencing an Exterminatus action as "liberating a planet" -- 08:25, December 16, 2014 (UTC)

I don't see why it shouldn't have the same meaning; BDZ includes as much ground-based mop-up operations as it does orbital bombardment. BDZ doesn't automatically mean the planet is uninhabitable... it just means the enemy presence has been exterminated ready for loyal Imperial forces to move in once more 00:46, March 7, 2016 (UTC)

Energy required Edit

I was just thinking; if a planet is solid granite, then in order to perform a BDZ operation in an hour, a single Imperial-class SD would need to deliver almost 4,500 GT of energy to a planet's surface every minute! 00:41, March 7, 2016 (UTC)
