On November 1, 2015, a complex $230 million U.S. military missile defense system test event, called "Campaign Fierce Sentry" Flight Test Operational-02 Event 2 (FTO-02 E2), was conducted at Wake Island and the surrounding ocean areas. The test involved a Terminal High Altitude Area Defense (THAAD) system built by Lockheed Martin, two AN/TPY-2 radar systems built by Raytheon, Lockheed's Command, Control, Battle Management, and Communications system, and guided missile destroyer with its AN/SPY-1 radar. The objective was to test the ability of the Aegis Ballistic Missile Defense and THAAD Weapon Systems to defeat a raid of three near-simultaneous air and missile targets, consisting of one medium-range ballistic missile, one short-range ballistic missile and one cruise missile target. During the test, a THAAD system on Wake Island detected and destroyed a short-range target simulating a short-range ballistic missile that was launched by a C-17 transport plane. At the same time, the THAAD system and the destroyer both launched missiles to intercept a medium-range ballistic missile, launched by a second C-17.
