The U.S. Missile Defense Agency, in cooperation with the U.S. Navy, conducted Flight Test Aegis Weapon System 33 (FTM-33) in the broad ocean area northwest of Hawaii, July 24.

The objective of FTM-33 was to intercept a raid of two Short Range Ballistic Missile targets with four Standard Missile-6 (SM-6) Dual II missiles.

Based on initial observations, one target was successfully intercepted. At this time, the agency was not sure if the other target was intercepted.

FTM-33 was the most complex mission executed by MDA (a raid of two test targets and two SM-6 Dual II salvos consisting of four missiles).  It was the third flight test of an Aegis BMD-equipped vessel using the SM-6 Dual II missile.

FTM-33 was initially scheduled for December 2020, but was postponed due to COVID-19-related restrictions on people and equipment transportation.

MDA will continue to assess the system’s performance based on the information gathered during the test.

The firing ship for the test was the USS Ralph Johnson (DDG 114).

The SM-6 Dual II missile is designed for use in the terminal phase of a short- to- medium-range ballistic missile trajectory.
