Anduril says its Barracuda-M missile family has been verified against the U.S. Air Force Weapon Open Systems Architecture (WOSA) standard—a design approach intended to let components and software evolve through common interfaces rather than forcing a redesign of the entire weapon. The company says an Air Force Research Laboratory (AFRL) test lab assessed the architecture across 14 domains over four days. That verification concerns compliance with the standard; it is not evidence of combat effectiveness or proof that every component can be swapped without integration work.
What “upgrade without rebuilding” means
A missile is a system of connected elements: sensors, navigation equipment, control functions, software and payload-related interfaces must work together. In a tightly coupled design, changing one element can require redesigning or retesting other parts that depend on it.
Open architecture seeks to reduce that coupling. WOSA defines common interfaces intended to let subsystems—including seekers, navigation modules, software and payloads—be developed, integrated and upgraded independently. In principle, a program can introduce a compatible new component through those interfaces instead of redesigning the weapon around it.
“Independently” does not mean “with no integration.” A replacement still has to meet the interface requirements and work with the rest of the system. Anduril’s account does not quantify upgrade time, cost savings or how many physical components can be exchanged without additional engineering.

What AFRL reportedly verified
In a September 23, 2026 release, Anduril said the AFRL Munition Open Architecture Test and Evaluation Laboratory (MOATEL) completed a four-day verification of Barracuda-M across 14 WOSA domains. The company said the assessment verified its software architecture against WOSA requirements in the domains tested and demonstrated modularity between its internal and external munitions data bus (MDB) implementations.
The 14 named domains were:
- Mission autonomy
- Seeker
- Inertial measurement unit (IMU)
- GPS
- Air-data sensor
- Propulsion
- Airframe control
- Target state estimator
- Altimeter-aiding navigation
- Clock
- Autopilot
- Guidance
- Navigation
- Munitions data bus (MDB)
Anduril quoted Jonathan Shaver, identified in its release as WOSA program manager and creator at AFRL’s Air Warfare Directorate: “Open architecture is only meaningful when it can be independently verified, and for WOSA that verification is through MOATEL”. The quotation and the Barracuda-specific test account are reported in Anduril’s release, not in an independently located public AFRL account.

What the verification does—and does not—establish
The result, as described by Anduril, supports a limited but meaningful conclusion: the company says its architecture was assessed for WOSA compliance in the named domains, including modularity between two MDB implementations. It does not establish that every listed subsystem was physically replaced during testing, that future upgrades will be plug-and-play, or that the missile’s operational performance was tested.
The available public account also does not establish classified capabilities, field performance, a particular upgrade’s cost or schedule, or how much redesign WOSA may avoid in practice. The 14-domain count is the scope Anduril reported, not a measure of battlefield effectiveness.

How this fits the Air Force’s wider architecture effort
Open interfaces are also part of a broader U.S. Air Force acquisition direction. In July 2026, the Air Force Life Cycle Management Center reported that the service had published its Agile Mission Suite Government Reference Architecture and Autonomy Government Reference Architecture, describing them as open-architecture standards intended to support modular integration and upgrades. That policy context does not independently confirm the Barracuda-M verification.
AFLCMC Executive Director Dennis D’Angelo said: “We can no longer afford to buy closed, proprietary platforms.” In this context, open architecture is an effort to make future integration less dependent on redesigning a whole platform whenever technology or mission requirements change.

Production and delivery remain company projections
Anduril said on September 23, 2026 that Barracuda production was underway, first customer deliveries were expected in early 2027, and the company planned to produce several thousand systems annually over the next several years. These are company-reported plans and forecasts; they are not confirmation that deliveries have begun or that the projected production rate has been achieved.
