Sutherland

The Sutherland (サザーランド, Sazārando) was designed and developed after the conquest of Japan/Area 11, the RPI-13 Sutherland is in many ways a refinement of its predecessor, the RPI-11 Glasgow. Though it's an advanced and effective design, much of the Glasgow's success comes from Britannia's overwhelming numerical and economical superiority to Japan. Further, the Glasgow is designed primarily to combat tanks and other "traditional" ground combat machines; this proves to be a liability, as its own success means that nations such as the Chinese Federation and EU began seriously pursuing Knightmare design. Thus, the Sutherland is created with the possibility of battles with other Knightmares in mind. Its design was later used as a basis for the RPI-209 Gloucester, a higher performance Anti-Knightmare Unit. A number of these Knightmare Frames were in the hands of the Black Knights, as well as a number of other resistance groups, during the first season, by means of theft or defection. Despite being overshadowed by the Gloucester, the Sutherland is still used in large numbers one year after the Black Rebellion.

Design and Specifications
The Sutherland features a redesigned, simplified cockpit system with improved life support and enhanced Landspinners, refined for higher speed and efficiency. Even though many of these improvements were passed back to the aging Glasgow in the form of upgrades, the Sutherland eventually replaced it as Britannia's main battle unit. It can be fit with an optional Float Unit backpack, consequentially changing the machine designation to RPI-13FA Sutherland Air (サザーランド・エア, Sazārando ea). Following his defection to Zero's side, disgraced Britannian noble Jeremiah Gottwald uses a Sutherland fitted with an air glide wing unit and Black Knights weapons in service of his young lord.

Purist Version
Members of the Purist Faction pilot Sutherland's with distinctive red markings on the shoulder armor, and Factsphere face plate. The unit at its core is just a standard Sutherland, although member's of the faction are commonly seen utilizing powerful weapons like Stun Tonfas, Jousting Lances, and even Chaos Mines.

Sutherland Air
In a.t.b. 2017, Knightmare developer Lloyd Asplund creates an experimental Knightmare Frame known as the Sutherland Air that incorporates several technologies developed for the Lancelot, including Blaze Luminous particle shields. It is distinguished from other Sutherland Airs by its light gray armor with light orange parts. Cecile Croomy makes use of this heavily modified Sutherland in a rescue operation during Black Rebellion, when the Avalon and its crew help evacuate students from an occupied Ashford Academy.



Sutherland Glinda
The RPI-13/G Sutherland Glinda is a variant of the Sutherland that appears in the manga and photo story, Code Geass: Oz the Reflection. The Sutherland Glinda is a mass production unit used as the main Knightmare Frame force of the Glinda Knights, and is piloted by Sokia Scerpa, Leonhard Steiner and Tink Rockheart. Each one is equipped with specific armaments that correspond to the fighting style of each respective pilot. During his battle against Jeremiah, Lyre also uses a Sutherland Glina against Jeremiah's Sutherland since the Vincent Gram was being overhauled.

Sutherland Pluton Custom
The RPI-13/PC Sutherland Pluton is a variant of the Sutherland that appears in the manga and photo story, Code Geass: Oz the Reflection. It is used exclusively by the Britannian special forces group, “Pluton”, which undertakes dirty jobs for the royal family. Since its interior frame and OS has been customized, it is more highly efficient than the regular Sutherland, although it possesses the same armaments. To distinguish it from regular Sutherlands, it has completely black armor along with purple shoulder armor and face-plate. One of them was piloted by Pluton member Cerberus, and was incapacitated by Orpheus in a custom Glasgow at a ruined village in southern Hungary.



Sutherland Sniper
The Sutherland Sniper is a variant of the Sutherland that appears in the manga and photo story, Code Geass: Oz the Reflection. Its main weapon is a modified rifle that fires a Hadron Cannon, along with a stylized shield in the shape of the Britannian crest. The currently only known unit shown so far is piloted by General Johann Schwarzer of the Glinda Knights.

Sutherland Club
The heavily modified Sutherlands created by Lloyd Asplund and code-named "Sutherland Club". During the early development stages of the video game Code Geass: Lelouch of the Rebellion - Lost Colors, Rai was supposed to pilot one of them if he were to join the Britannian Military. However, the idea was rejected and the Sutherland Club lost its role in favor to the Lancelot Club.

Code Geass: Akito the Exiled
The Sutherland is a fifth generation Knightmare Frame, like the one from the original series, that was developed from the Glasgow with improved mobility. The ones used by the Knights of Raphael are silver with purple/blue trims while the St. Michael knights are white and red. The main army retain the purple colour scheme though now with a small red and black checkerboard design on the chest, knee, and ankle armors. The St. Michael Knights' Sutherlands are also armed with extendible battle axes mounted on their left arms.
