Missile defense statistics in 2026: the budget, systems, and fielded force in one view
Missile defense spending is no longer a narrow line item. The FY 2025 and FY 2026 numbers show a program set that stretches from homeland defense and regional coverage to left-of-launch efforts, radar coverage, ship-based interceptors, and allied deployments.

At a glance
Big number: FY 2025 requested $28.4 billion for missile-defense capabilities across homeland, deployed forces, allies, and partners (DoD FY 2025 Defense Budget release).
Next big number: FY 2026 sought $40.2 billion for Missile Defeat and Defense programs (DoD FY 2026 Weapons PDF).
Core balance: FY 2025 split the request across $10.4 billion for the Missile Defense Agency, $9.5 billion for regional and strategic missile-defense capabilities outside MDA, and $8.5 billion for missile defeat or left-of-launch activities (DoD FY 2025 Defense Budget release).
Operational scale: By the end of FY 2026, there will be 63 total BMD-capable ships requiring maintenance support (MDA FY 2026 OP-5).
Fielded coverage: MDA continues supporting 13 AN/TPY-2 radars (MDA FY 2026 OP-5).
Long-term spending: MDA has spent over $194 billion on missile defense since 2002 (GAO-23-106011).
What the FY 2025 and FY 2026 budgets show
The clearest headline in the missile defense statistics is scale. FY 2025 requested $28.4 billion for missile-defense capabilities across homeland, deployed forces, allies, and partners, which shows the portfolio is designed as a layered mission rather than a single system (DoD FY 2025 Defense Budget release).
That same FY 2025 request breaks into three major pieces:
- $10.4 billion for the Missile Defense Agency (DoD FY 2025 Defense Budget release)
- $9.5 billion for regional and strategic missile-defense capabilities outside MDA (DoD FY 2025 Defense Budget release)
- $8.5 billion for missile defeat or left-of-launch activities (DoD FY 2025 Defense Budget release)
The split matters because it shows that missile defense spending is not concentrated entirely in interceptors. A large share goes to enabling pieces such as sensors, command-and-control, discrimination, and non-intercept options that support the broader defensive architecture.
FY 2025 also included $13.5 billion in missile-defense programs in the weapons budget summary (DoD FY 2025 Weapons PDF). Within that total, the strongest line items were:
- $8.7 billion for Ballistic Missile Defense Systems (DoD FY 2025 Weapons PDF)
- $2.7 billion for Tactical Missile Defense (DoD FY 2025 Weapons PDF)
- $1.0 billion for Operational System Development (DoD FY 2025 Weapons PDF)
- $0.6 billion for Communications and Electronic Equipment (DoD FY 2025 Weapons PDF)
- $0.5 billion for Advanced Component Development (DoD FY 2025 Weapons PDF)
That mix suggests two things at once. First, the program is still heavily weighted toward deployed missile-defense hardware and operations. Second, enough is still flowing into development and electronic support to keep the architecture moving forward rather than frozen in place.
FY 2026 pushed the topline even higher. The request for Missile Defeat and Defense programs reached $40.2 billion (DoD FY 2026 Weapons PDF). On its face, that is a substantial jump from the FY 2025 request level, and it reinforces the idea that missile defense is now one of the largest and most multi-layered capability sets in the defense budget.

Major systems and fielded assets
The statistics point to a layered force built around several major systems rather than a single shield.
Ground-Based Midcourse Defense
The Ground-Based Midcourse Defense system remains the homeland backbone. In FY 2025, development continued on NGI to supplement 44 currently deployed GBIs (DoD FY 2025 Weapons PDF).
That number is important because it frames the scale of the existing ground layer. The architecture is not theoretical. It is already fielded, already defended, and already being extended with next-generation intercept capability.
Operationally, MDA said the GMD fielded weapon system is operated by the 100th Missile Defense Brigade headquartered at Schriever Space Force Base (MDA FY 2026 OP-5). The same fielded weapon system also includes the 49th Missile Defense Battalion at Fort Greely, Alaska, and the 100th Missile Defense Brigade at Vandenberg Space Force Base (MDA FY 2026 OP-5).
Two more support details show how the system is structured:
- GMD Fire Control has two redundant fire-control nodes at Fort Greely (MDA FY 2026 OP-5)
- GMD Fire Control has two redundant fire-control nodes at the Missile Defense Integration and Operations Center at Schriever Space Force Base (MDA FY 2026 OP-5)
That duplication matters because missile defense is only as useful as its ability to keep control and command functioning under stress.
Aegis Ballistic Missile Defense
Aegis BMD is the mobile, forward-deployable layer in the data set. MDA describes it as a capability that can destroy short-, medium-, and intermediate-range ballistic missiles in midcourse and shorter-range missiles in terminal phase (MDA FY 2026 OP-5). It also provides long-range surveillance and track capability to the missile-defense system (MDA FY 2026 OP-5).
The Aegis BMD fact sheet adds several concrete markers:
- Eight Japanese destroyers have been upgraded with Aegis BMD operational capabilities (MDA Aegis BMD fact sheet)
- The SM-3 Block IIA is a 21-inch diameter variant of the SM-3 (MDA Aegis BMD fact sheet)
- SM-3 Block IIA deployment was planned to begin in 2021 (MDA Aegis BMD fact sheet)
- Romania’s Aegis Ashore site was certified operational in 2016 (MDA Aegis BMD fact sheet)
- Poland’s Aegis Ashore site was projected to be completed no earlier than fiscal year 2022 (MDA Aegis BMD fact sheet)
- In 2020, an Aegis BMD destroyer intercepted an ICBM-threat representative target with an SM-3 Block IIA missile (MDA Aegis BMD fact sheet)
These facts show a program that is both sea-based and shore-based, with allied integration built into the system rather than appended at the edge.
THAAD
THAAD is another clear anchor in the architecture. The THAAD fact sheet says a battery has four main components: launcher, interceptors, radar, and fire control (MDA THAAD fact sheet).
The system has a fairly compact operational profile:
- A THAAD battery uses eight interceptors per launcher (MDA THAAD fact sheet)
- A THAAD battery can have up to nine launchers (MDA THAAD fact sheet)
- The AN/TPY-2 radar used with THAAD is the largest air-transportable X-band radar in the world (MDA THAAD fact sheet)
- THAAD completed 17 successful intercepts in 17 attempts since program initiation (MDA THAAD fact sheet)
- Eight THAAD batteries have been procured (MDA THAAD fact sheet)
- Seven THAAD batteries are currently fielded to the U.S. Army (MDA THAAD fact sheet)
- MDA delivered 799 operational THAAD interceptors to the U.S. Army and FMS customers as of 1 Oct 2023 (MDA THAAD fact sheet)
- Two THAAD batteries were procured by and delivered to the UAE (MDA THAAD fact sheet)
- Saudi Arabia has signed multiple FMS cases for delivery of seven THAAD batteries (MDA THAAD fact sheet)
That combination of intercept performance, fielded batteries, and foreign military sales makes THAAD one of the most mature and widely distributed pieces in the data set.
Program-by-program comparisons
A useful way to read missile defense statistics is to compare what each line of the enterprise is actually supporting.
O&M comparison table
| Program | FY 2024 actuals | FY 2025 enacted | FY 2026 O&M | Source |
|---|---|---|---|---|
| MDA total | $569,336 thousand | $598,506 thousand | $720,365 thousand | MDA FY 2026 OP-5 |
| Aegis BMD | $79,460 thousand | $74,208 thousand | $152,247 thousand | MDA FY 2026 OP-5 |
| GMD | $174,086 thousand | $182,298 thousand | $166,305 thousand | MDA FY 2026 OP-5 |
| Missile Defense System Radars | $226,852 thousand | $251,198 thousand | $284,785 thousand | MDA FY 2026 OP-5 |
| THAAD | $88,938 thousand | $90,802 thousand | $117,028 thousand | MDA FY 2026 OP-5 |
The table shows several patterns.
First, the total MDA O&M line rises from $569,336 thousand in FY 2024 actuals to $598,506 thousand enacted in FY 2025, then to $720,365 thousand in FY 2026 (MDA FY 2026 OP-5). That is a clear upward operational requirement.
Second, radar support is a major cost center. Missile Defense System Radars go from $226,852 thousand in FY 2024 actuals to $251,198 thousand enacted in FY 2025 and $284,785 thousand in FY 2026 (MDA FY 2026 OP-5). That tells you the sensor layer is not a side note; it is a major operating burden in its own right.
Third, Aegis BMD nearly doubles from $74,208 thousand enacted in FY 2025 to $152,247 thousand in FY 2026 (MDA FY 2026 OP-5), which suggests a large increase in operational support needs.
Fourth, THAAD rises steadily from $88,938 thousand in FY 2024 to $90,802 thousand in FY 2025 and $117,028 thousand in FY 2026 (MDA FY 2026 OP-5), indicating steady expansion rather than an abrupt jump.
Fast facts by system
- GMD is the homeland layer with 44 currently deployed GBIs and NGI under development (DoD FY 2025 Weapons PDF).
- Aegis BMD is the flexible sea-and-shore layer with allied deployments and proven intercept history (MDA Aegis BMD fact sheet).
- THAAD is the terminal defense layer with 17 intercepts in 17 attempts and 7 fielded batteries (MDA THAAD fact sheet).
- AN/TPY-2 is central to the sensor network, with 13 radars still supported by MDA (MDA FY 2026 OP-5).
Operational footprint and readiness
The missile defense numbers also reveal the size of the day-to-day force footprint.
MDA said that by the end of FY 2026 there will be 63 total BMD-capable ships requiring maintenance support (MDA FY 2026 OP-5). That is not just a planning number. It is a maintenance and readiness burden spread across a large mobile fleet.
Radar coverage is similarly broad. MDA continues supporting 13 AN/TPY-2 radars (MDA FY 2026 OP-5). Of those, five operate in forward-based mode at fixed radar sites 24 hours a day, 7 days a week, 365 days a year, while eight operate in terminal mode when integrated with THAAD batteries (MDA FY 2026 OP-5).
Two of the eight terminal-mode radars are permanently stationed outside the continental United States (MDA FY 2026 OP-5). That detail matters because missile defense is not just a domestic homeland mission. It is also a globally distributed sensor-and-interceptor posture.
The operating model for GMD and THAAD shows the same pattern: fixed sites, redundant nodes, distributed batteries, and persistent support requirements. In missile defense, readiness is built into the budget line by line.
Selected missile defense benchmarks
A few of the most useful benchmarks from the data set deserve to sit side by side.
- MDA has spent over $194 billion on missile defense since 2002 (GAO-23-106011)
- GAO-23-106011 was the 20th annual report in GAO’s missile-defense series (GAO-23-106011)
- As of March 2025, Guam’s defense system included six missile launchers and one radar (GAO-25-108187)
- FY 2025 missile-defense programs totaled $13.5 billion in the weapons budget summary (DoD FY 2025 Weapons PDF)
- FY 2025 missile-defense programs included $8.7 billion for Ballistic Missile Defense Systems (DoD FY 2025 Weapons PDF)
- FY 2025 missile-defense programs included $1.5 billion for the Defense of Guam (DoD FY 2025 Weapons PDF)
Those benchmarks show how missile defense shifts between global scale and site-specific needs. The general budget is large, but specific missions such as Guam defense still require explicit program lines and separate operational planning.
Pull-quote style takeaways
$28.4 billion was requested for missile-defense capabilities in FY 2025, and $40.2 billion was sought for Missile Defeat and Defense in FY 2026 (DoD FY 2025 Defense Budget release; DoD FY 2026 Weapons PDF).
13 AN/TPY-2 radars, 7 THAAD batteries, and 63 BMD-capable ships show that the system is spread across sensors, interceptors, and maritime support (MDA FY 2026 OP-5; MDA THAAD fact sheet).
The ground layer still matters: FY 2025 continued development of NGI to supplement 44 deployed GBIs (DoD FY 2025 Weapons PDF).
Why it matters
The main story in missile defense statistics is not a single spectacular figure. It is the way multiple large figures line up across budgeting, fielding, sustainment, and allied integration.
On the budget side, the portfolio runs from $13.5 billion in the FY 2025 weapons summary to a $40.2 billion FY 2026 request for Missile Defeat and Defense (DoD FY 2025 Weapons PDF; DoD FY 2026 Weapons PDF). On the operational side, MDA supports 13 AN/TPY-2 radars, maintains multiple GMD nodes, and sustains 63 BMD-capable ships by the end of FY 2026 (MDA FY 2026 OP-5). On the force structure side, the data include 44 deployed GBIs, 7 fielded THAAD batteries, and a growing allied and regional footprint (DoD FY 2025 Weapons PDF; MDA THAAD fact sheet).
The most important takeaway is that missile defense is a layered system with layered costs. The numbers show spending for interceptors, radars, command and control, ship support, missile defeat, and forward-based coverage all moving together rather than separately.
If you are tracking missile defense as a policy topic, procurement story, or force posture metric, the data point to one consistent conclusion: the mission is broad, the footprint is persistent, and the support requirement is growing rather than shrinking.
