Army pushes open-API architecture in Fort Carson hackathon to link sensors, shooters and C2 networks

The Army's effort aims to shift military systems away from stovepiped architectures toward modular, API-driven networks designed to improve interoperability across domains.

Key Highlights

  • Operation Jailbreak brings soldiers, engineers, and industry partners together to test and validate API-based battlefield systems at Fort Carson.
  • The initiative seeks to reduce manual system integration by enabling automated data sharing across multiple domains and platforms.
  • Over 70 Army capabilities are being connected through shared APIs in a live environment, accelerating interoperability and innovation.

FORT CARSON, Colo. - The U.S. Army is testing a new "Right to Integrate" approach to battlefield systems architecture at Fort Carson, bringing soldiers, engineers, and defense industry partners together to rapidly connect sensors, platforms, and command-and-control systems through exposed application programming interfaces and real-time data sharing.

The effort, called "Operation Jailbreak," is the first major sprint under the Army’s broader integration initiative, which aims to shift military systems away from stovepiped architectures toward modular, API-driven networks designed to improve interoperability across domains.

More than 600 participants from more than 50 industry partners are supporting the three-week event, where engineers are exposing and documenting APIs across more than 70 Army capabilities in a live integration environment. Army officials said the effort is intended to reduce reliance on soldiers as manual system integrators during operations by enabling more automated data exchange and fusion across tactical networks.

Senior Army leaders participating in the event include Army Secretary Dan Driscoll; Brent G. Ingraham, assistant secretary of the Army for acquisition, logistics, and technology; Dr. Alex Miller, chief technology officer to the Army chief of staff; and Col. Shermoan Daiyaan, director of the Army’s Pathway for Innovation and Technology office.

Army officials said the initiative reflects a broader shift in acquisition strategy away from post-fielding, platform-by-platform integration toward systems designed from the outset with open interfaces that can be more easily connected across formations and mission sets.

API-driven integration model

At the center of Operation Jailbreak is an effort to standardize and expose system interfaces so that sensors, effectors, and command systems can exchange data without custom middleware or manual translation layers.

Industry teams are working in "validation zones" on the Army network to connect systems through shared APIs, enabling rapid experimentation with sensor-to-shooter and multi-domain data flows.

Driscoll said the effort was informed in part by observations of allied operations in Europe.

"The 'aha' moment for this hackathon was specifically in Germany," Driscoll said, referencing exposure to Ukrainian operational networks during allied engagements. "I walked out saying, 'Oh my God, we have to move right now.'"

Dr. Alex Miller said legacy architectures have often required soldiers to manually aggregate information across multiple disconnected systems during operations.

"That has forced our people to be the integration point, which is really rough if you’re cold, tired, wet, and hungry," Miller said. "Now you can pipe all of that data into one thing, and those people can actually be the crew chief for AI rather than part of the machine itself."

Army officials said a key focus of the effort is improving integration of air and missile defense and counter-uncrewed aircraft system capabilities, particularly in response to rapidly evolving drone threats in the U.S. Central Command area of responsibility.

Officials said software updates and integration packages developed during the sprint are expected to be transitioned to deployed forces within approximately 30 days, pending testing and validation.

Open architecture and API Marketplace

To support faster integration, the Army launched an API Marketplace on 6 May. Officials said the platform allows vendors to securely publish, document, and manage interfaces to accelerate collaboration and integration across programs and systems.

Army engineers, cyber personnel, and legal teams are embedded with participating industry teams to support real-time validation and resolve integration issues during the sprint.

Brent G. Ingraham said the effort reflects a structural shift in how the Army approaches capability development and acquisition.

"We’ve executed something here that for years we’ve tried to figure out how to integrate capability," Ingraham said. "All this does is make our soldiers safer and more effective in the field."

The Army plans to further test and validate integrated capabilities developed during the event at software integration laboratories in Huntsville, Ala., and Aberdeen Proving Ground, Md., prior to operational use.

Col. Shermoan Daiyaan said the level of collaboration between government and industry has been significant.

"These teammates have done more than what we asked them to do," Daiyaan said. "They’ve connected with new systems all along the battlefield."
