Like a number of mobile suits in the Age of the Warring Space States, the Anchor is a "mixing build" constructed from the salvaged parts of old mobile weapons, including the F89 Gundam F89. As the Gundam F89 was created early in the Formula Project as a testbed unit, the Anchor is over 18 meters tall. While most mixing build mobile suits have poor balance, the Anchor was restored by experienced engineers and thus does not have balance issues. The thruster unit on the back of the mobile suit is also similar to those of the Crossbone Gundam units. Unlike most mobile suit of the era, the Anchor can also utilize rare beam weaponry.

Since the Zanscare Empire's attempted invasion of Earth, the circumstances of mobile suit development and maintenance have drastically changed. The ongoing wars in space resulted in the manufacturing and maintenance of MS becoming much more difficult. As a result, many mobile suits are older machines that have been repaired or shambled together. The Anchor is one such unit, utilizing the frame of the Gundam F89 and various other MS parts. Exceptions to this are more recent Zanscare and League Militaire mobile suits, which still have some parts available.
