Metal Gear Wiki:
Chrysalis was an AI weapon developed by the CIA Peace Sentinel in the early 1970s. Its main function was to serve as a VTOL attack craft.Chrysalis was one of the four AI weapon types developed by Huey Emmerich as part of the Peace Walker Project. As with all AI units, it was equipped with an AI pod, designated TJ-Chrysalis-6000. It was divided into two units: a freely-moving front unit and a rear section, connected by a bar.

Three propeller units gave it great aerial maneuverability. Due in part to its unmanned status, Chrysalis could utilize extreme G-force maneuvers that most aircraft of the time were incapable of, allowing it to quickly evade missile attacks. If significantly damaged, the Chrysalis will end up landing temporarily while the AI fixes it, with the AI also doing repairs while it is still in the air. It was also capable of airlifting objects that are at least as heavy as 500 tons. This is especially evident with its airlifting Peace Walker from the Crater Base.
