Metal Gear Sahelanthropus

Metal Gear Sahelanthropus, also known as ST-84, is a towering bipedal nuclear-equipped walking tank introduced in Metal Gear Solid V: The Phantom Pain. Developed in the 1980s by Huey Emmerich for the Soviet Union and the XOF organization, Sahelanthropus represents a major advancement in the Metal Gear series, bridging the gap between earlier prototypes like the Shagohod and Peace Walker, and later models such as Metal Gear REX. Its name, derived from the extinct hominin species Sahelanthropus tchadensis, reflects its role as a key evolutionary step in the development of these dangerous weapons of mass destruction.

Standing at 24 meters tall when fully upright, Sahelanthropus is heavily armored with depleted uranium, weighing approximately 23 tons. Initially designed to be controlled by an AI pod, the design was later adjusted to accommodate a pilot, with the unit eventually being piloted by a child due to design constraints. The machine’s sensor radius is capable of detecting targets up to 200 meters away.

Sahelanthropus is equipped with a formidable array of weapons, including an 18.5-meter railgun capable of launching nuclear warheads, twin 12.7mm Gatling guns, six guided missile launchers, and four surveillance mine launchers. It also features two metallic archaea nano-fiber blades for melee combat, a flamethrower, and the ability to deploy corrosive metallic archaea. The machine’s arsenal is rounded out with a nuclear armament that includes a uranium-enrichment archaea self-destruction mechanism and an intercontinental ballistic missile.

In terms of design, Sahelanthropus can transition between a crouched form, similar to earlier Metal Gears, and a fully upright stance, giving it enhanced mobility and versatility in combat. With its advanced weaponry and potential for nuclear escalation, Sahelanthropus plays a central role in the game’s narrative, representing the increasing danger of nuclear proliferation and the ethical dilemmas that come with such destructive power.
