I imagined that so much focused energy through the energy weapons (I know solid ammo doesn't do that) would degrade them, much like in Star Wars, the laser tips on the X-wings have to be replaced every so often for that very reason.

I'm not sure how laser weapons work in Star Wars, so I can't say much about that.

Generally speak, though, since many lasers depend heavily on mirrors to collimate the beam you wouldn't want a laser weapon to be so powerful that it can damage itself with its own output.

When it comes to particle beams, the beam never touches the interior of the accelerator because doing so would be akin to the structural failure of a gun's barrel during firing... it'd wreck the weapon.

A particle beam would still be throwing matter at a target, albeit extremely minute amounts at very very high velocities in collimated beams.

By definition, yes.

So it sorta does make sense that it has a magazine, if you think of it as more of a tank of elemental gas. 

Well, yes and no.

As I touched on in my previous post, the explanation(s) we've gotten about how most (non-dimensional) energy weapons in Macross work presents them as weapons that can be operated indefinitely as long as the mecha's reactors continue to run.  They get any charged particles or plasma they need from the reactor itself.  That's why Mirage's comment in the novelization is so odd.  It implies the VF-31 has a beam weapon (the gunpod) for which that is not true.

This would be in line with how the MDE Beam Matrices worked before I guess, as you would be loading up particalized fold quartz bits to use as your plasmified matter.

That's a whole different animal.  Two, really.  You're potentially conflating two different weapons.

MDE shells and warheads are essentially a miniaturized version of the Dimension Eater bomb that destroyed Gallia IV.  They use fine particles of fold quartz to create fold waves that "activate" the super heavy quantum in the shell/warhead so that its immense gravity tears adjacent matter apart as a short lived pseudo black hole before it drops back into fold space.

MDE beam weapons use fold quartz as a catalyst to generate super heavy quantum and manipulate its gravity with fold waves so that the weapon fires a particle beam made up of short lived pseudo black holes that pull the matter they come in contact with into fold space.  As far as we know, the beam version doesn't consume any fold quartz.

 

1 hour ago, RangerKarl said:

My contention really was with the terminology of 'optical munition/stores', as peebees don't work like that.

True... as the actual definition of "optical weapon" implies the weapon is firing collimated electromagnetic radiation, which particle beams aren't.

I thought the fold quartz particle source would still get expended from constant firings. The way Frontier always had it, it ended up being a bit of a finite resource. 

I'm now wondering if the Master File writers also had that belief about the MDE particle guns, and sorta followed up on that with the ammo-dependent particle gunpods. In the case of another Vajra problem you could just swap your magazine types, instead of getting hard-locked into an MDE-spec weapon. 

If traditional PBWs are funneling excess plasma from the reactor, it could be that there are some issues with trunking that stuff from the engine, through the hand hardpoint into the gunpod. Before Frontier the energy gunpod was a one-shot attachment for the Nightmare. The magazine system might also be a way to avoid that engineering choice.

Based on the descriptions we have, the fold quartz isn't the particle source in a direct sense.

The particulars of how a Gravity and Inertia Control system creates heavy quantum are not given, but fold carbon (or fold quartz) is said to be a key component of the system that serves to somehow catalyze the creation of heavy quantum and produces fold waves used to control the heavy quantum's gravity.  It's not consumed in the process.

 

5 hours ago, RangerKarl said:

Oh, it definitely is.

As far as we know, fold quartz is either not a naturally-occurring substance or if it does occur in nature it is almost impossibly rare.  The Vajra use an unknown biological process to refine raw fold ore (fold coal) into fold carbon and fold quartz.  The ancient Protoculture studied the Vajra extensively and were eventually able to develop a technological means of synthesizing fold quartz.  Humanity is still more or less at the point of picking over Protoculture ruins and old Vajra carcasses and nests for leftover fold quartz, so fold quartz of a usable purity for many essential purposes is quite rare and incredibly valuable.  

Humanity is noted to be working on a means of synthesizing fold quartz the way they do fold carbon, but there is no indication that the process has borne fruit so far.  (Master File suggests that the answer is "probably not" in the 2060s.)

Master File has yet to devote a volume to a craft that was equipped with Heavy Quantum or MDE beam weaponry as standard like the VF-171EX, VF-27, or YF-29, or YF-30.

The brief description of MDE weapons and the VF-171EX's MDE beam cannon in the VF-25 Master File is very much in line with the previously-stated description from the official setting materials.  Fold quartz particles are used in the trigger mechanisms of MDE bullets and missile warheads in order to provide the fold waves that activate the super heavy quantum and cause the "fold bomb" effect, while the MDE beam weapons are firing particle beams made up of the super heavy quantum produced by a fold quartz-equipped GIC.  There's no mention of a "beam cartridge" system like the one found on the VF-31's LU-18A gunpod writeup in the VF-31 Master File.

Potentially.  It might raise some awkward questions about the VF-27's beam gunpod if true, since it's not 100% clear if the VF-27's beam gunpod was a charged particle gunpod that was upgraded to a heavy quantum and later MDE beam specification or if it was a heavy quantum one from the jump.  If the VF-27 could pull off getting the necessary particles from the engines to the gunpod, it'd make one wonder why the VF-31 couldn't.

Outside of the original series where the first-ever generation of Zentradi adapting to Earth's culture struggled, the only time we really see that is with the 33rd Marines in Frontier.

I'm assuming you're referring to strictly animated series, because that is true. It's mostly the cases we see in spin offs and side material where either that 1st generation struggles, or they and future generations adopt the worst parts of culture.

 

VF-X's villains do what they do to resurrect their way of endless war, to the point that Rival being glad that he surrendered to the Earthling's by dying as a warrior. The Musicalture presents the Neo-Zentran movement as one by a younger generation to militarize the literally defenseless Macross 29, but then you get scenes where they get stunned by the main character's singing. Most of M3's antagonists are explicitly or implied to be Zentradi, such as Struggle, the terrorist group who are made of Zentradi defectors from the UN. The New York Liberation League, which is in odds with the local Neo York government, consists of a variety of aircraft including the Gnerl, and Mission 2 where you fight and grab Moaramia away, the setting is the planet Cristrania, which is a fundamentalist Zentradi colony who's harboring the terrorists designing the Variable Glaug.

 

Edit: There was also the 2nd Battle of Macross City that was alluded to in timelines and VF-X2, the one that not only banned giants on Earth but also had tens of thousands of Zentradi fleeing away as a result in anti-Earth colony ships....Why would Macross Chronicle tie the Macross 5 fleet to insurgents escaping judgement other then the fact they're also Zentradi emigrants is beyond me. I don't even know why that's a additional bit of lore to begin with!

 

Of course they're not as prominent as the animated stuff, but it's one of those things where smaller material is indicative of the bigger fandom and/or creator mentality.

Algenicus, though... I've been unable to find anything on that one.  It's such a specific name, and they went to the trouble of spelling it out in English... I get nothing for any possible spelling of it, and the kana doesn't produce any results in the Japanese wiki either.

I wouldn't be surprised if it's an attempt to integrate Zentradi language into the world a bit more. Not only it has some design language of their ships, but we get that plenty in Plus where many of Sharon's songs are sung in Zentran, and "Deculture" kind of becomes a loan word by Frontier.

Was there ever an attempt of using higher quality of normal fold carbon for 5th Gen VFs? You think with such a finite source the government at large would try for a more economical alternative. On that train of thought, does fold carbon has its own supernatural qualities aside from being used on ships? As in, could it resonate in a way through music?

That's a bit of a disservice to them.  The Neo Zentran political movement in the Macross 29 fleet advocates for rearmament for economic reasons not a desire for warfare.

Spoiler

Under Vigo, the Neo Zentran's goal is to abandon the current fleet government's policy of unarmed total pacifism and reestablish the fleet's New UN Forces in order to save the fleet's economy from an economic death spiral. 

Abandoning the fleet government's current policy of unarmed total pacifism and having some sabers to rattle would, according to the Neo Zentran, allow the fleet to secure fair trade agreements with its neighbors instead of being an extreme doormat.

Reestablishing the fleet's New UN Forces will, in and of itself, create a HUGE number of badly needed public and private sector jobs.

Yeah, but these are minor incidental level affairs that are cleared up by a single special forces unit.  It's not like these groups represent a majority of Zentradi or even a significant minority.  They're basically the spacefuture version of the militant wackos that every developed country produces in some small numbers.  (The Zentradi may be overrepresented simply because their natural fight-or-flight response is stuck on "fight" due to genetic engineering.)

I don't think that's it.  There haven't been any ships with explicitly Zentradi names thus far, excluding the SDFN-08 General Vrlitwhai Kridanik (which is named for a person), and this looks to be structured like a masculine given name in Roman Latin.  The suffix -icus normally means "of/from" or "belonging to" or "pertaining to".  It's almost like "genticus", which would be "belonging to a gens (family)"... which would definitely fit the theme of Moaramia's journey.

Eh... that depends.  Master File contends that the VF-24/25/26/27 already use the highest-quality fold carbon that could be reliably produced for the various systems and features that require it (e.g. reaction engines, certain beam weapons, active stealth, EFAM, the Aegis pack's fold wave radar, etc.).  

It's not pure enough to make a working Inertia Store Converter, which is why fold quartz is necessary in the first place and the scarcity of it is why it's used as sparingly as the New UN Forces and various defense companies can get away with.  The best you can do with very high purity fold carbon is to make the Queadluun-Rau's inertia vector control system, which is a similar technology that isn't quite as fit for purpose because its main focus is optimizing propellant consumption.

Master File suggests the Earth New UN Spacy is experimenting with using the latest ultra-high purity fold carbon as a substitute for fold quartz in a Fold Wave System.  Its account suggests that it does work, but only about 1% as well as the Vajra Queen-level fold quartz used in Alto's YF-29.

Fold quartz is just purified fold carbon.  There's nothing really supernatural about either of them... not any more than, say, dilithium in Star Trek is.  It's multipurposeful, but all of the things it can do are treated in a purely scientific context.  They both produce fold waves in various applications, produce heavy quantum in GIC systems, etc.  Fold quartz is a purer form that simply does everything fold carbon can do better.

Between Master File's above-mentioned assertions WRT using ultra-pure fold carbon in a Fold Wave System in exchange for greatly reduced performance and Fire Bomber's Sound Energy system and Sound Booster being built around a modified fold system, it seems a safe-ish bet to say that fold carbon can be used to resonate with/transmit songs.

Thematically, I can buy it. The VF-31 was a plane whose design program was initiated by a local government group trying to spark economic growth. I can believe them cutting the cost for that, maybe due to something like "not-invented-here" syndrome or a misplaced desire to save pennies on things like certification while wanting a big ticket bulletpoint for sales.

[Sildani]

So a thought I just had... dangerous, I know. When did fold carbon/quartz become so widespread and vital? Was the SDF-1 filled with it in order to work and the original Macross shows just not touch on it? Was it purely to use as a McGuffin for Frontier? How did the SDF-1 and other superdimensional devices work if not with fold carbon/quartz?

[RangerKarl]

I think Seto has much better citations, but I do recall Isamu getting threatened with an assignment to the coal mines of some space colony. I guess they had the idea all the way back then.

Fold carbon and fold quartz were both officially introduced to the Macross setting in Macross Frontier.

Fold carbon was introduced to the setting and story partly as a way to explain how fold quartz can be "dropped in" to improve the performance of existing OTM rather than needing to develop new versions of technology around it and concoct new explanations for how key technologies work.  It was effectively retconned into having always been a part of OTM from the very beginning as a key component in the Gravity and Inertia Control tech that underpins most OTM.  Prior to that point, there wasn't an explanation for exactly how a GIC system goes about creating artificial gravity.  Supplemental technical material like Master File subsequently went absolutely ham tying this into everything from explaining why the early fold systems Humanity built didn't work very well to why there are such massive leaps in engine performance between certain generations and even why some fold boosters are single-use.

As with several other late additions, one might say this was foreshadowed in an earlier work.  Specifically Macross Dynamite 7, where it was noted that crystalline galactic whales were hunted because their bodies contained materials used in the construction of fold systems.  The Frontier novelizations similarly turned a macguffin from Macross VF-X2 into foreshadowing of fold quartz's existence and potential.

It would be fair to say that, at least in post-Frontier publications, the ASS-1/SDF-1 Macross was fairly packed with fold carbon since it's used in the GIC systems of thermonuclear reactors, gravity control systems, inertia control systems, fold navigation, fold communication, cross-dimensional radar, particle beam cannons, holographic projection systems, thermonuclear reaction warheads, the ship's main gun system, active stealth tech, and any/all of the same found on the battle pods and auxiliary craft found aboard the derelict ship.

While Frontier-era materials did establish that the raw/least pure grade of fold ore is sometimes called fold coal, I don't think any source has connected it to the supposed coal mines on Banipal that Isamu was threatened with in Plus.

EDIT: The reason some have speculated that Banipal might be a fold coal mine is that it wouldn't really make any sense for a civilization that possesses room temperature superconductors, lossless energy storage, high-efficiency wind and solar power, ultra-high efficiency thermonuclear generators and a mindset VERY focused on preserving the biospheres of planets would bother mining fossil fuels.

EDIT 2: Of course even then it doesn't really make sense, since there isn't a need to mine the raw materials for fold carbon when it can be synthesized in industrial quantities using existing technology.

Clarification

[Seto Kaiba]

My exploration of energy weapons in Macross turned up a few more interesting oddities.

First is that Master File actually made the beam cannon confusion worse since apparently its version of the VF-4 has not one, not two, but four different forearm-mounted guns for the VF-4.  Three of which look virtually identical.  One being a version of the same ROV-20 laser cannon used by the VF-1, the next being a charged particle beam cannon powered off the reactors, and the third being a charged particle beam gun powered by "beam cartridges".  Interestingly, it seems to imply that the VF-27's beam gunpod is NOT a beam cartridge type.

Second, Master File didn't come up with the idea that the VF-1's RO-X2A Strike pack cannon was a laser weapon.  They got that from Sky Angels.  Instead of being a safer and more conventional gas dynamic laser cannon, the original version is an inertial confinement fusion-pumped x-ray laser cannon.  Essentially, a less insane but repeatably usable version of Project Excalibur's heinously bonkers nuclear bomb-pumped x-ray laser system concept.

[RangerKarl]

I...well, if you do have a sun in a bottle on tap, why would you not try to use it as a lasing gain/excitator medium somehow?

On the one hand, why wouldn't you take advantage of such a grotesquely OP technology for stimulated emission?

On the other, I'd be very worried if one of my colleagues came to me and said "Remember that time we tried to make a wildly impractical nuclear bomb-pumped x-ray laser cannon to shoot down ICBMs?  I think I know how we can make it work and put it on a plane now."

 

That's not to say that there haven't been similarly bonkers weapons tossed out in newer material.  The VF-22 Master File introduces a Strike Pack beam cannon for the VF-22 that's a scaled-down version of a Zentradi warship's guided focusing beam cannon.  It uses a dedicated compact thermonuclear reactor to vaporize heavy metals in order to use launch that vapor as a high-velocity particle beam with an output power in the hundreds of megawatts.

I've been building the excellent new HG VF-31J Siegfried, and the build process actually left me with a question about its weapons - what are the two little gold cylinders in the head? They appear to be laser cannons, but official specs for the siggie list only the head-mounted laser. Are these vents, or cameras, or something? I've no idea.

As far as we know, the only weapon mounted in the VF-31J's monitor turret (head) is the obvious one: its Mauler ROV-127E 12.7mm multi-band fiber laser cannon.

The barrel-like structures on the VF-31J, as well as similar ones found on other VFs, have not been identified.  It's possible that it's some kind of structural component used to hold the monitor turret in place in Fighter and GERWALK modes or that it's related to one of the many sensor systems packed into the monitor turret.

Reminds me of the Vulcan head mounted machine guns in gundam mobile suits. maybe the vents were intended to cool them or something originally, and then maybe someone just forgot they were there

could also be just connectors for fighter mode to keep it stable or for recharging the head laser gun

That's pretty unlikely.  After all, the reason that the monitor turrets of Battroids are armed with laser weapons instead of conventional anti-aircraft cannons is that, back when the SDF Macross series was in development, Kawamori et. al. realized pretty early on that a Battroid's head was going to be far too small to plausibly fit a then-modern air-to-air machine gun like the F-14's M61A1 Vulcan or the Panavia Tornado's BK-27 and enough ammunition to make it remotely usable.

Spoiler

To put it in perspective, the VF-1's head (minus laser cannons) has a footprint of about 1 cubic meter.  In its most compact and space-efficient configuration, the M61A1 is 1.83m long, 0.65m wide, and about 1.16m tall.  The gun alone would be 38% bigger than the Battroid's entire head, leaving no room for any of the many sensors that are needed for a Battroid to operate.

It's been a bit of a creator's in-joke ever since... so much so that the VF-0 Master File directly references it as an in-universe design obstacle the Stonewell Bellcom team working on the VF-0 encountered in the 2000s.

 

In a way, you could say Macross's insistence on head-mounted energy weapons is a rebuke of Gundam's infamously useless "head vulcans"...

Spoiler

Gundam's RX-78 Gundam could get away with having two 60mm rotary cannons in the head because it's much bigger (18m as opposed to 12m), doesn't have to make any accommodations for transformation (so no need for local power storage), and contains only a handful of sensors (two internal binocular cameras, two exterior monocular cameras, one short-ranged radar, and some directional microphones), and gives most of the back of the head over to the ammo drums. 

Even then, those 60mm cannons only have enough ammunition for about 15 seconds of fully automatic fire and the rounds themselves aren't powerful enough to reliably inflict meaningful damage on enemy mobile suits at close range.

The Gundam gave most of its head over to this massive pair of cannons that were, in the final analysis, only really good for annoying other Mobile Suit pilots, harassing infantry, and shooting down the occasional plane.

By sticking with laser or particle beam weapons, the Battroid has a coaxial gun that will never run out of ammunition and can be plausibly made powerful enough to inflict meaningful damage because their main design constraint is power availability.  It also retains enough space for all the optics and other sensors the Battroid requires to go about its business.

That’s kinda why I was thinking it may be something like a connection point for recharging the beam weapon. Definitely too small for anti Valkyrie use weapons, although anti personnel is an odd stretch. But a connection point either for stability or recharge. Maybe it heats up during recharge and is why it has vents behind that point, but I’m really no expert
