The IMS Sentinel is IMC Supercarrier an Interstellar Manufacturing Corporation vehicular spacecraft in Titanfall. It is the flagship for the IMC fleet until it's destruction at the hands of James Macallan and the Frontier Militia during the events of the campaign.
During the battle of Angel City it provides air support for IMC ground forces and suffers heavy damage from Militia fighters. During the campaign mission "Assault on the Sentinel," the Frontier Militia take control of the Repair Dock's defence cannons and attempt to shoot the carrier out of the sky. The carrier is either blown out of the sky by cannon-fire, or manages to make an emergency landing with Vice Admiral Marcus Graves at the helm, depending on the victor of the mission. No matter the outcome of the mission, the Sentinel is a casualty of the war.
