Vintage MS: Playing With Specs

MSV-R and Vintage MS Specs

So what's new in the Year of the Snake version? Well, let's start with the new

**MS Encyclopedia**.

In the previous 2009 edition, the black-and-white line art pages added a bunch of MSV specs from Hobby Japan's Gundam Mechanics series. In some cases (like the Gelgoog Cannon), these conflicted with the Sunrise-authorized specs that appeared in the color section. And as per usual, the MS Encyclopedia editors mangled the heck out of them - for example, the Zaku Desert Type and Marine Type specs are mixed up, and likewise for the MS-07H-4 Gouf and the YMS-08A. But in whatever mangled form, these specs were retained in the new edition and copied-and-pasted into the color pages; they've also been popping up in toy and model packaging, and they seem to be the basis for a lot of the MSV-R specs. So we may as well try to get used to them.

Which means, among other things...

**FA-78-1:**Full weight is listed at 93.1 tons, thruster output at 60,500 kg. I first saw these figures in a 2000 issue of Dengeki Hobby magazine, and now they're in the MS Encyclopedia.

**RGM-79SC:**They kept the Sunrise-authorized base weight of 44.2 tons, but added the other specs from Gundam Mechanics (full weight 75.3 tons, generator output 1,390 kW, thruster output 68,000 kg, sensor radius 7,300 meters).

**MS-06D:**Base weight is back to 61.3 tons, as per Entertainment Bible 1, rather than the 48.8 tons previously listed in the MS Encyclopedia. This change, too, has been reflected in the MSV-R series.

**MS-06E:**All specs as per Gundam Mechanics.

**MS-06M:**Still using the Entertainment Bible 1 specs, although now they're all mixed up with the Desert Type.

**MS-06R-1A:**Base weight is back to 61.8 tons, as per Entertainment Bible 1 and Gundam Mechanics, rather than the revised figure of 56.8 tons. (The MSV-R series says 61.8 tons, too.) Thruster output is listed as 52,000 kg a la Gundam Mechanics, rather than 49,800 kg.

**MS-06R-2:**All specs as per Gundam Mechanics, including a base weight of 49.5 tons rather than the 58.2 tons previously listed in the MS Encyclopedia. As I've noted, this figure, which presumably reflects the new lightweight materials used in the R-2, is exactly 80% of the R-1A's base weight. More on that in a bit.

**MS-06Z:**I don't think the base weight was

*deliberately*changed, but they pasted in a figure of 43.8t for this, maybe from the Rick Dom.

**MS-07H:**All specs as per Gundam Mechanics. The base weight, which was 58.5 tons in the previous MS Encyclopedia, has reverted back to Gundam Mechanics's value of 63.9 tons.

**MS-07H-4:**Previously listed as 65.2 tons in the MS Encyclopedia, and then reduced to 62.5 tons. Now listed as 55.7 tons because they mixed up its specs with the YMS-08A.

**MS-14B:**Still using the same specs as in Entertainment Bible 1. Base weight 53.5 tons, full weight 76.8 tons, etc.

**MS-14C:**Now this is interesting. Gundam Mechanics lists this with a base weight of 55.8 tons, full weight 79.8 tons. In the new MS Encyclopedia, they're still using the lighter base weight of 44.5 tons from the previous edition, along with a revised full weight of

**68.5 tons**. In other words, they adjusted the full weight from Gundam Mechanics to match the lower base weight; this is the only genuinely new spec in the entire book!

A couple of weird developments in the First Gundam pages, too...

**MS-09:**Full weight now listed at 79.9 tons instead of 81.8 tons. This was the figure listed in the HG-UC kit manual, too.

**MS-09R:**Previously listed together with the original Dom with a single set of specs. This seems to have led to a bunch of people assuming the Rick Dom

*also*has a base weight of 62.6 tons. This time, they've attempted to restore the previous figure of 43.8 tons, but mistyped it as 48.3 tons. Go figure.

**MS-14:**Now listed with a base weight of 53.5 tons (same as the MS-14B), alongside the previously reported full weight of 73.3 tons. More on that in a minute, too.

First, let's think about the

**MS-06R series**. If we embrace the MS-06R-2 specs from Gundam Mechanics, we have a base weight of 49.5 tons and a full weight of 75.0 tons. The 25.5 ton difference between those two figures is partly carried equipment and partly propellant; see previous discussions of mass ratios for more on this. Based on precedent established in the Zeta and ZZ specs, the equipment weight is probably a round number between 4.0 tons (the minimum we see in later shows) and 6.0 tons (the payload of the Hizack). That gives us three likely scenarios:

49.5 + 6.0 + 19.5 tons = 75.0 tons (mass ratio 1.35)

49.5 + 5.0 + 20.5 tons = 75.0 tons (mass ratio 1.38)

49.5 + 4.0 + 21.5 tons = 75.0 tons (mass ratio 1.40)

According to the MSV series, the R-2 type has 18% more propellant than the R-1A. So if we divide the propellant by 1.18 and then add the weapons payload to it, we find that the difference between full and base weights for the R-1A type should be somewhere between 22.2 and 22.5 tons. Basically, whatever the precise breakdown between propellant and carried weapons, the specs for the R-1A type are pretty much locked in by those of the R-2 (or vice versa).

So what does this tell us about the R-1A? Basically, if its base weight is 61.8 tons, it really ought to have a full weight of 84 tons and a mass ratio of 1.24 to 1.28.

Now, the

**Gelgoog series**. The notion that the standard Gelgoog has a base weight of 53.5 tons and a full weight of 73.3 tons actually works out really nicely! This fits in logically between the Gyan (base weight 52.7 tons, full weight 68.6 tons) and the original Dom (base weight 62.6 tons, full weight about 80 tons). Here are a few sample equipment/propellant breakdowns...

53.5 + 7.0 + 12.8 tons = 73.3 tons (mass ratio 1.21)

53.5 + 6.0 + 13.8 tons = 73.3 tons (mass ratio 1.23)

53.5 + 5.0 + 14.8 tons = 73.3 tons (mass ratio 1.25)

That's considerably less propellant than the MS-06R-2, and a few tons less than the R-1A, which helps explain why Zeon rushed out high mobility backpacks for this machine.

What about the B and C types? Well, if the B type has had its base weight cruelly stolen by the backpack-less A type, then we'd need all-new figures for it. One model might be the Gelgoog Marine; its base weight is 45.1 tons, exactly three tons more than the A type, and its full weight is 81.3 tons. If we bump that base weight up to 56.5 tons (three tons more than the A type's

*new*weight) and keep the full weight unchanged, then it would have between 17.8 and 19.8 tons of propellant and a mass ratio of 1.28 to 1.32 in the three scenarios above.

One other consideration about the B and C types. The MSV-R specs for the MS-14BR and MS-14C-1A types are clearly based on these - the BR type has a base weight of 53.3 tons, slightly less than the B type, and the C-1A has a base weight of 56.2 tons, slightly more than the heavier weight given for the C type. But the C-1A can carry multiple backpacks - it's pictured with a cannon-less high mobility type, which can be swapped for a cannon type, apparently without affecting its base weight.

This suggests that the base weights of the B and C types, and their MSV-R variants,

*don't include the backpacks*. That right there would explain why the A and B types have the same base weight!
