CSIS Missile Defense
@Missile_Defense
The Missile Defense Project at the Center for Strategic and International Studies @CSIS.
A major loss for the institution. Please join us in remembering Andrew Schwartz:
CSIS mourns the loss of our Chief Communications Officer, Andrew Schwartz. For 20 years, he led with vision and integrity, shaping how CSIS engaged the world. His leadership, mentorship, and legacy in strategic communications will have a lasting impact: csis.org/analysis/memor…
A new report from @Missile_Defense describes what is needed to realize a proliferated, resilient surface-based sensor architecture to maintain the ability of U.S. air defense to see and make sense of the battlespace. Read the full report here: csis.org/analysis/mesh-…
Really great recap of the report:
Great talking with @masao_dahlgren about @Missile_Defense’s new report on the need for a ground-based, proliferated meshed AMD sensing network🚀 Read the article in @tectonicdefense defense here: tectonicdefense.com/csis-wants-air… And the full CSIS report here: csis.org/analysis/mesh-…
Recent Department of Defense budgets have seen lower Terminal High Altitude Area Defense (THAAD) interceptor procurement numbers, triggering renewed concerns about missile defense interceptor inventories. Read more from @Missile_Defense: csis.org/analysis/unite…
""Our current architecture is built around active sensors, radars...shining a flashlight into the dark. And we'd like to have night vision goggles..."

Affordable mass has become the watchword of defense modernization, be it swarms of drones or satellite constellations. What could such an approach mean for air and missile defense? Read more from @Missile_Defense: csis.org/analysis/mesh-…
LIVE NOW: Join @masao_dahlgren and @tomkarako for a discussion on passive and proliferated sensor networks. Ask live questions here: docs.google.com/forms/d/e/1FAI…

TOMORROW: At 11:00 am, @Missile_Defense rolls out their new report, "Mesh Sensing for Air and Missile Defense," assessing a vision for passive, proliferated sensor networks for surface-based air and missile defense. Watch here: csis.org/events/report-…
C-sUAS is an everybody problem. The CSIS missile defense team is doing its part, one UAS at a time. If it flies it dies.
Field day with Team MDP:
New from @wesrumbaugh: For 2026, the White House requested to buy 25 THAAD interceptors (Talon), and Congress added another 12 in the reconciliation bill. But these decisions were likely made before the recent Middle East engagements; it's worth considering a supplemental. @CSIS

In the lead-up to our release, @masao_dahlgren discusses the Art Gallery Problem, a famous math problem that matters for air and missile defense. How do you choose where to place tens or hundreds of sensors?
If you want to build a proliferated sensor network, a problem arises: where do you put them? You want to minimize the number used to cover a certain area. On first thought, you'd imagine that some kind of hexagonal mesh would be a good approach.
Low-footprint passive sensors, even if just for cueing, could make a difference for a lot of missile defense engagement scenarios.
On Monday, @tomkarako and @masao_dahlgren will roll out a new report on passive sensor meshes for air and missile defense—tune in! csis.org/events/mesh-se…
A look at budget trends in the ground-based AMD sensor enterprise. Big, big blocks for LTAMDS, OTHR, Sentinel A4. We'll be talking about sensors more come July 21.
We can't wait to show you something.

July 21. Be there.
#ICYMI: Retired @ArmySMDC CG Lt. Gen. Dan Karbler @CSIS highlighted @USArmy air defenders' combat power and called for more recognition, funding and modernization, and discussed SMDC's potential role in the Golden Dome initiative. Listen here 👉tinyurl.com/37sese5h
📡"We have 15 Patriot battalions...really 14 that are available." 📡3 in the Indo-Pacific, 1 in EUCOM, rest service retained. Among those, 1 in CENTCOM "for close to 500 days." 📡 "plans on the table" to increase to 18 battalions, not including those for Guam, plus add IFPC
General Mingus: "The new LTAMDS [radar] is 360º. It also goes from about 85 kilometers up and 85 kilometers out to 300 by 300...So you could take those same 15 Patriot battalions we have today, give it IBCS and LTAMDS, and...it's like immediately doubling that capability."
