MS-05A Zaku I Early Type

In the anime and manga Mobile Suit Gundam universe, the MS-05 Zaku I was the first successful mobile suit design to be developed by the Zeonic Company in the Principality of Zeon's quest to develop a combat-capable mobile suit that used the AMBAC System and the Minovsky ultracompact fusion reactor. The Zaku I was first designed and built in U.C. 0075, as the MS-05A Zaku winning the arms war against the EMS-04 Zudah. It wasn't put into mass-production until later that year, as the MS-05B Zaku I. The last production run of the MS-05B is in U.C. 0077, before it was replaced by the newer MS-06 Zaku II unit.

The successful use of these suits prompted the Zeon Navy to commission ships that could carry them into combat, primarily the Musai-Class Light Cruiser. The Zaku I was rendered obsolete by the Zaku II before the beginning of the One Year War, and thus they were relegated for use in the rear lines as supply and construction suits. They still saw some action, though, as colony gassers in the One Week War and, towards the end of the war, they joined frontline combat to reinforce the Zeon's weakening military lines.

Variations
The Zaku I, like many of the Zeon's mobile suit lines, had a few variations of the basic model, such as the MS-05S Zaku I Commander Type and MS-05J Zaku I Land-Warfare Type.



MS-05J Zaku I Land-Warfare Type
The land warfare Zaku I was little more than a stock Zaku I repainted in region-specific colors.

Few of these suits would see action, for while the Zaku II series was no longer being mass produced, it was not difficult to obtain one. Most Zaku I's were assigned to pilots that requested them, or to newly-formed squadrons that were unable to obtain the best equipment available. Some would see action in southeast Asia, with at least one assigned to Commander Topp. More would be assigned to the Midnight Fenrir teams. And while Manning and Swaggard would eventually take on additional mobile suits, Austin would keep his Zaku I throughout the remainder of the war, adding different weapons and option parts to suit his liking. These included a shield, the MS-07B Gouf’s heat sword, and even a shield salvaged from a fallen RGM-79 GM.



MS-05S Zaku I Commander Type
The MS-05S Zaku I Commander Type was the personal mobile suit of Lieutenant Commander Gerhart Schmeisser, the founder and leader of the Midnight Fenrir Corps. Before the One Year War, Schmeisser was already a decorated mobile suit pilot, and in the opening days of the war proved himself as a soldier. However, during an attack on a facility in New Guinea to clear the way for the Operation British colony drop, Schmeisser was severely wounded in action when a booby-trapped railgun facility blew up. Schmeisser survived, though his injuries prevented him from returning to active combat duty. Despite this handicap, Schmeisser persuaded Admiral Kycillia Zabi to create the Midnight Fenrir Corps. Under his command, the Midnight Fenrir would go on to distinguish themselves in the One Year War. Despite the restriction from combat duty, Schmeisser still used his MS-05S in training missions and in simulations, providing a valuable service to his team even though he could not fight.

The differences between this mobile suit and a regular MS-05B Zaku I were small. The only major differences were a second shoulder dome on the right shoulder, the striking (and often misleading) white and silver custom paint job, and a new shield mounting the fearsome heat saber seen on the MS-07B Gouf. The obvious bonuses of a commander’s type mobile suit aside, the MS-05S was little different from the standard Zaku I being used by the Home Defense Corps, and various out-of-the-way Zeon bases.
