The S.H.I.E.L.D. Helicarrier is an advanced, rebuilt aircraft carrier. The Helicarrier is an aircraft carrier fitted with four massive lift fans and engines capable of lifting it into the air. The ship is able to both sail on the water and fly and hover in the sky.
The first Helicarrier seen was used as a base of operations for the Avengers when they were facing off against Loki and his Chitauri armies. After the Avengers captured Loki, the god broke out of his holding chamber with the help of his mind-controlled S.H.I.E.L.D agents and fatally wounded Phil Coulson in the heart. As a result of his injuries, Coulson later died on the carrier.
After the Battle of New York, the World Security Council tasked and funded S.H.I.E.L.D to work on a new initiative codenamed "Project Insight". The project entailed three of these Helicarriers to protect the people of Earth. The Helicarriers would be used as a first-response weapon designed to strike out against potential threats before they became threats in the first place. However, when the HYDRA agents that had infiltrated S.H.I.E.L.D were activated, they attempted to use the project to kill the 20 million people that HYDRA had deemed to be threats to their cause. The plan was foiled by Steve Rogers and Natasha Romanoff.
