First of all, I'd like to thank everybody, but particularly Mark064, Chris and the great toysdream: I'm glad that someone appreciated these small notes.
And now, let's start with the scheduled contribution!
Mobile Suit Z Gundam
Although the series is quite well covered by MAHQ profiles, I have some little remarks and additions. Of course, there are also many non-listed minor mecha, but they're mostly civilian, such as the unnamed small plane used by Amuro in episode 13 or the nearly ubiquitous jeeps and ele-cars.
AEUG (Anti-Earth Union Group)/Karaba
H.L.L.V.
Unit type: heavy lift cargo vehicle
Notes: This large transport capsule, which name stands for Heavy Lift Launch Vehicle, is essentially the same as the H.L.V. seen in
0083. It's used by AEUG forces in epsiode 16 (and in the corresponding part of
Mobile Suit Z Gundam II - Lovers) to launch from Hickory spaceport, storing inside the MSN-00100 Hyaku Shiki. As explained in Asahiya Shuppan Mobile Suit Gundam Film Book Series 1 - Zeta Gundam Part 1, its payload is from 10 to 100 times that of an ordinary shuttle; all around the circumference of its detachable lower section it's provided of 8 external fuel tank and several nozzle thrusters.
Small type spaceboat
Unit type: space launch
Notes. This small boat is used by Char, Shinta and Qum in episode 27 to board on Argama. A clear depiction can be seen on Mobile Suit Zeta Gundam Mechanical Edition Vol.2 (Newtype 100% Collection n.4).
Temptation
Notes: According to Take Shobo The Gundam Chronicles - The History of Mobile Suit Gundam Animations 1979-1999, this name designated a class of shuttles, rather than a single unit. This idea is supported also by the explicit "Temptation class" heading for the scratchbuild model appeared on March 2004 issue of Dengeki Hobby Magazine (lately on Advance of Zeta official artbook vol. 3, page 53). In any case, at least three units are seen on
Mobile Suit Z Gundam: one is used by AEUG, one by Earth Federation Forces (also in episode 12) and one, not listed in MAHQ profiles, by Titans' Jamitov Hymem (at the beginning of epsiode 21).
A different type of
space shuttle (nameless, as far as I know), is that used in episode 13 by AEUG to launch from Kennedy base.
Transport plane
Unit type: cargo plane
Notes: This strange medium-sized plane is used by Amuro in episode 14 (and in the corresponding part of
Mobile Suit Z Gundam I - Heir to the Stars) to desperately ram Buran Blutarch's NRX-044 Asshimar.
Transport ship
Unit type: space transport ship
Armament: single cannon x 1, machinegun x 2
Notes: During episode 11 at least seven of these ships are used to carry supplies for the AEUG fleet before the Jaburo drop operation. Each ship drags a double set of three containers.
Earth Federation Forces
MS-06K Zaku Cannon
Notes: As far as I know, the space use refined models embarked on the Alexandria class (refit) Hario and seen in episode 11 belong to Titans rather than EFF, so they should be listed under that faction.
RGM-79R (RGM-179) GM II
Notes: Although this isn't their most distinctive MS, the red-colored GM IIs is used also by Titans, so it should be listed under them too.
Some of you probably already know it, but as a mere curiosity I note that besides the red RGM-179 and the green RGM-79R other two GM II color schemes are present in the show:
1) classic Titans black and blue (partially seen in episode 1, when Quattro enters in Gryps colony; only feet and the lower part of the legs are visible, but basing on the aspect of calves, ankle support units and on the sole / thruster pattern, one can exclude that it may be a fourth RX-178, being in the meantime reasonably sure that this is a black RGM-179; as a less likely alternative one can identify it as an RX-78 in Titans colors, whereas the only remaining possibility, i.e. a RGM-79Q GM Quel, is obviously impossible since these latter MSs were designed many years after the release of
Mobile Suit Z Gundam);
2) "Nemo colors" (a few AEUG use RGM-79R units are painted just like MSA-003 Nemo, such as some of those appearing in episodes 10 and 11).
RX-77-2 Guncannon
Notes: Perhaps it's not exactly the kind of things that MAHQ profiles list, but a natural size replica of Hayato Kobayashi's Guncannon C 108 is clearly seen in episode 13, at the aerospace museum of the Kennedy Space Center.
As observed by Mark064 in another thread of this forum, in the same scenes other mechas are seen: they are clearly based on
Xabungle designs, but since Dengeki MS Encyclopedia 2003 and other sources explicitely show them (labeled as EFF prototype MSs, albeit nameless), they cannot be considered as mere "inside jokes"...In any case I reported them only for the usual sake of completeness.
Vehicles and Support Units
Missile car
Notes: The armored cars equipped with an 8-tube missile launcher seen at Jaburo base in episode 12 are most likely intended to be the same as tose featuring in
Mobile Suit Gundam and
0080.
Trailer
Notes: This wheeled platform with a crane arm is rather similar to the version featured in
0083. It's used both by Earth Federation Forces (episode 12, transporting a Temptation shuttle inside Jaburo hangar) and Titans (episode 2, recovering the RX-178 unit 03), so it should have a listing for each of these factions.
Space launch
Unit type: space launch
Notes: This small boat embarked on the Alexandria class cruiser in episode 6 is clearly depicted by Take Shobo The Gundam Chronicles - The History of Mobile Suit Gundam Animations 1979-1999.
Titans
MS-06M (MSM-01) Zaku Marine Type
Notes: Although its main spec is the same as the
MSV version, the M type Zakus featuring in
Mobile Suit Z Gundam have their original cockpit replaced by a RMS-106's linear seat. Most sources, including the original Bandai 1/144 scale model kit, Take Shobo The Gundam Chronicles - The History of Mobile Suit Gundam Animations 1979-1999 and Asahiya Shuppan Mobile Suit Gundam Film Book Series 1 - Zeta Gundam Part 1 properly refer to it as
MS-06M Marine Hizack.
RX-121-2A Gundam TR-1 [Advanced Hazel]
Notes: I'm not completey sure that the unit briefly appearing at Konpeitoh on
Mobile Suit Z Gundam III - Love is the Pulse of the Stars can be considered an Advanced Hazel, since it shows a slightly different color scheme. More in particular, its arms are grey, whereas those of the "standard" RX-121-2A are blue: this leads me to regard it as the Primrose-equipped Hazel, i.e.
RX-121-2 [Hazel Owsla], which from the rear is very similar to Advanced Hazel, differing just for the arm color (grey instead of blue).
Dodai Kai
Notes: As can be seen in episode 38, when the Garuda class Melord launches two RMS-106 riding grey-colored Dodai Kais to escort the RX-160 on a Base Jabber, this atmospheric sub flight system is used also by Titans forces, and therefore it should be listed under this faction as well.
Spacejobber "Gator"
Notes: I suppose that the transliteration of the original
katakana GETA- used by MAHQ is based on official sources, but as a curiosity, it must be noted that according to Mobile Suit Zeta Gundam Mechanical Edition Vol.2 (Newtype 100% Collection n.4) and Mobile Suit Gundam Char's Counterattack (Newtype 100% Collection n.10) the term
Geta (in
kanji, indicating a sort of Japanese footwear similar to clogs) is used as general nickname to designate all sub flight systems from Dodai YS onwards.
Musai Kai class
Notes: I don't think these ships really belong to the Titans, and I suspect that they should most properly listed under a separate
Republic of Zeon heading. Indeed, sources as Asahiya Shuppan Mobile Suit Gundam Film Book Series 1 - Zeta Gundam Part 1 explicitely assign these refined Musais to Republic of Zeon forces, together with the
Chivvay Kai class and some green
RMS-106 (among which there is at least a commander antenna-equipped unit).
