Phase Shift armor
Phase Shift, or "PS" armor, is an armor system that uses electricity to reduce the damage from all forms of physical attacks although in most practicalities, PS armor makes a mobile suit virtually immune to solid body impact attacks. When PS armor powers up, a hissing sound can be heard and the grey surface of the mobile suit's armor is overlaid in color, which appears to be alterable by entering different values in the Armor Voltage section of the OS. Once powered up, the PS armor requires a steady flow of energy to maintain although power consumption spikes momentarily whenever the mobile suit is hit. ZAFT commander Andrew Waltfeld, after watching the GAT-X105 Strike fight, calculated that the Strike in standard use can take approximately 76 hits from the missiles of a TMF/A-802 BuCUE, before the energy usage drains the battery. This example illustrates that even solid ballistic weapons can eventually overpower Phase Shift Armor. Most beam weapons are able to overpower PS Armor faster than ballistic weapons. However, should a power failure occur, caused by either prolonged use or the use of high energy beam weapons, which will further drain the mobile suit's battery, the PS armor will power down, leaving the mobile suit vulnerable to even the simplest physical attack. Phase Shift armor is also able to protect the unit from great heat and thus making the unit possible for atmospheric re-entry. Currently, the upper limit of Phase Shift armor is unknown.
Because PS armor draws energy off of a mobile suit, the suits so equipped must have a means of replenishing that energy, or risk power depletion. During the war, the existence of Neutron Jammers limited mobile suits and mobile armors to operation on an energy battery (some mobile suits were equipped with various turbine engines to extend their operating time, but almost none had truly unlimited operational ability). Due to the limited amount of energy within each battery only a certain amount of power is ever allocated to the PS armor system. This limitation prevents the armor from being able to nullify higher forms of energy such as beam weapons. Because of this, most PS armored mobile suits carry a shield with an ablative anti-beam coating for defense against beams.
Nuclear power could give a PS armored mobile suit theoretically unlimited operating time. However, during the Bloody Valentine War, the widespread use of N-Jammers made this impossible without the use of Neutron Jammer Cancellers; afterward, the Treaty of Junius Seven outlawed nuclear-powered mobile suits. Only a few nuclear-powered mobile suits were made in any event, including the YMF-X000A Dreadnought, ZGMF-X09A Justice, ZGMF-X10A Freedom, ZGMF-X11A Regenerate,ZGMF-X12A Testament, ZGMF-X13A Providence, and the ZGMF-X999A ZAKU Trial Type. Each of these units incorporated an N-Jammer Canceller in their design, negating the effects of the N-Jammers in the field. With the tremendous amount of energy made available through the use of nuclear power, even greater amounts of energy could now be allocated to PS armor. ZAFT's superweapon GENESIS allocated so much power to its PS armor that it was able to nullify direct energy beam attacks from the Eternal and Kusanagi, including the Kusanagi's "Lohengrin" Positron Blaster Cannons.
Orb also improved the PS armor with their own technology and installed it on the MBF-02 Strike Rouge. This minor improvement allowed the Strike Rouge to configure attributes of its PS armor, such as changing its power usage and strength as well as the colors. Unlike VPS (see below), this must be done outside of combat.
Trans Phase Armor
During the first Bloody Valentine War, OMNI Enforcer experimented with ways to improve the usefulness of PS Armor, leading to the development of Trans Phase Armor (TP) in which the equipped suit do not change color when the armor is activated. TP armor is basically a two-layer armor system, with the PS Armor on the inner layer of normal armor. The inner PS Armor only activates when the outer layer is breached, thus saving energy and preventing the consumption of large quantities of energy non-stop until the armor is turned off. This results in TP armored units having a longer operational time as well as more energy for their power-hungry beam weapons. However, TP armored mobile suits is still vulnerable to heavy attack from multiple vectors (a sufficiently powerful weapon could also overpower the TP armor). The most notable examples mobile suits with Trans Phase Armor include the Earth Alliances second-generation GAT-X Gundams - the GAT-X131 Calamity Gundam, the GAT-X252 Forbidden Gundam, and the GAT-X370 Raider Gundam. At around the same time, Junk Guild's Lowe Guele also though of such a two-layer armor system and it was installed around the cockpit of the MBF-P03 Astray Blue Frame Second L by Orb's Morgenroete, Inc..
Variable Phase Shift Armor
Developed by ZAFT, the Variable Phase Shift armor is the latest version of phase shift armor and the most energy efficient. It allows the MS to automatically alter the strength and by extension the power consumption of the PS Armor, depending on what combat configuration or situation that MS is in. As a result, the MS's colors changes. Unlike Strike Rouge's color-shifting PS, VPS is capable of changing its strength in the field, however the programming for this is still most likely done off-field beforehand.
The VPS technology was first applied on the Second Stage Series of mobile suits built by ZAFT in CE 73. EA most likely acquired the technology after the theft of three of these units from Armory One. It is also possible that they acquired that technology as a result of their brief alliance with Orb in CE 73. The ZGMF-X56S Impulse had at least three VPS settings, one for each Silhouette packs. Some other MS with VPS are ZGMF-X12A Testament Gundam , ZGMF-X20A Strike Freedom Gundam, ZGMF-X19A Infinite Justice Gundam, the ZGMF-X42S Destiny Gundam, & the ZGMF-X666S Legend Gundam.
Phase Shift armor (PS) was developed by the Earth Alliance, and first rolled out in Cosmic Era 71. It remains in use as of CE 73. The first mobile suits to be equipped with PS Armor are the so-called "Gundams", GAT-X102 Duel, GAT-X103 Buster, GAT-X105 Strike, GAT-X207 Blitz and GAT-X303 Aegis. Later, both ZAFT and the Orb Union's Morgenroete, Inc. were able to study and duplicate the armor design. Over time several different versions of PS armor were developed, which are more efficient than the original version. As a result, the first variant is not produced anymore.
- The concept of the Phase Shift armor is the inverse of Universal Century's I-field generator, which defends against beam weaponry but has no effect against physical attack.
- The Phase Shift armor is similar to the Luna Titanium Alloy (Gundarium Alloy) from the Universal Century that can withstand strong physical attacks from the Zeon mobile suits, such as the Zaku's 120mm and 90mm shells and even the Dom's 360mm Bazooka.
- It is possible Phase Shift can create a beam reflective like coating. When GENESIS deactivates its Mirage Colloid, its mirror panels are grey (on the main body, not its Mirror Blocks), but when its Phase Shift is activated, the plates take on a blue color.
- The fact that all the Gundams, from the Strike Gundam to the Aegis are gray prior to the activation of PS armor could be a reference to the fact that the RX Gundam was originally supposed to be gray and white, not white, blue, and red.
- In Super Robot Wars Alpha 3 and Super Robot Wars J, the Phase Shift armor was implemented awkwardly - while Beam weapons still harmed them, a lot of attacks were either greatly reduced in damage or outright negated despite being energy-based, such as Mazinger-Z's Breast Fire and Getter Robo G's Getter Beam, both energy attacks but not actually Gundam-type beam weaponry. Even some Gundam-type beam weapons, such as ν Gundam's Fin Funnels and Freedom Gundam's HiMAT Full Burst are still affected by Phase Shift armors, since they are not marked as "Beam Weapons" in the game's system. This was fixed in subsequent SRW installments.
- This issue might have came about from trying to replicate the armor's power from the series alongside broad definitions of non-beam weaponry. Something similar reared its head in the past in Super Robot Wars regarding the beam absorb defense: It absorbs any energy-based attacks, not just beam weapons from the Gundam series.
- In Super Robot Wars series, Phase Shift armor reduces non-beam and non-energy damage by 1500, while the VPS reduces non-beam and non-energy damage by 2000. Both of them consume 10 energy when used. Trans-phase armor reduces non-beam and non-energy by 1500 but only costs 5 energy per use.
- In Gundam Assault Survive, Phase Shift and Trans Phase Armor become available as purchasable MS accessories aside from being innate features of specific CE MS. The unit will display a second shield meter when it is equipped, which depletes when taking physical damage, but recharges over time, the rate depending on how the unit is tuned. If used in the early UC timeline missions, the unit will be practically invincible against every mobile suit that is not carrying a beam weapon, especially Zaku IIs and Ground GMs.
- In Gundam Battle Assault 3 Featuring Gundam SEED, Phase Shift armor works in a completely different way. Instead of only reducing melee and impact damage, it actually protects from energy based long range attacks.
- In SD Gundam Capsule Fighter Online, Phase Shift armor reduces physical projectile damage by 75%. However, physical melee damage isn't dealt with.
- In Dynasty Warriors Gundam Reborn, Phase Shift and its Trans-Phase variant acts as a Burst mode that prevents flinching from attacks. However, this Burst is only available to the Aegis, Buster, Blitz, Providence, Forbidden, Raider and Calamity, respectively.
