The Department of Defense’s landmark $1.45 trillion budget request for fiscal year 2027 includes $938 million in support to the Guam Defense System and its Joint Program Office.
According to the DOD’s budget request overview, existing defense systems, that includes the Aegis Ballistic Missile Defense, Patriot missiles, and the Terminal High Altitude Area Defense systems, will be leveraged to “expedite the development and fielding of Guam defenses.”
In its budget highlight, the Army is seeking upwards of 857 THAAD interceptors for the next fiscal year. For the defense system as a whole, the price tag sits at $10.5 billion in mandatory spending with $907 million in discretionary spending.
Spending also accounts for interceptor obsolescence mitigation efforts, ground component modifications, the Stockpile Reliability Program, and radar redesign kits secure servers.
The DOD is also looking to procure 78 SM-3 Block IB missiles and 136 SM-3 Block IIA missiles for the Aegis defense system.
According to the DOD, the fiscal year 2027 budget would cost some $5.48 billion to procure the munitions.
For the Indo-Pacific theater specifically, the Army is looking at a $49 million missile procurement request.
That is part of the force’s $2.2. billion Pacific Deterrence Initiative, that addresses “the unique challenges of the Indo-Pacific theater, prioritizing regionally-focused solutions over broadly applicable programs.”
The Army is looking to strengthen its presence in the region, partly through maintaining ballistic missile defenses in the Pacific.
“Technologically, the focus is on advancing the Integrated Air and Missile Defense system to create a protective shield for U.S. and allied forces,” according to the Army’s budget highlight.
The force is looking to continue building more missile infrastructure across the Pacific theater including for the GDS, but new projects include new construction in the Republic of the Marshall Islands.
“This involves new construction for launcher and radar sites and extensive maintenance for facilities at Kwajalein Atoll,” the Army wrote.
The U.S. war in Iran has threatened missile stockpiles, according to national media reporting.
Deterring China
One of the lines of effort outlined in the DOD’s 2026 National Defense Strategy is the continued deterrence of China.
“In support of President Trump’s goal for a stable and fair relationship with China, the [DOD] will create the military conditions for a balance of power in the Indo-Pacific.”
This involves a strong “denial defense” along the “first island chain” which includes Japan, the Philippines, Taiwan and other islands. The “second island chain” cuts through the heart of the Marianas.
Meanwhile, the U.S. defense strategy Indo-Pacific would see the U.S. leaning on its allies in the defense of the region.
At least 5% of U.S. ally’s gross domestic product would need to be spent towards defense, according to the DOD. The department plans to advocate that as a “new global standard.”
