Key Takeaways

  • Archer Aviation will acquire Wisk Aero, SkyGrid and Insitu from Boeing, combining eVTOL aircraft, unmanned systems, autonomy software and airspace management capabilities.
  • Insitu adds a profitable defense operation with over $200 million in annual revenue, customers across 35 countries and an established global support network.
  • Boeing will receive an equity stake in Archer Aviation and retain access to Wisk autonomy technology through a collaboration and technology-sharing agreement.

Archer Aviation has signed definitive agreements to acquire Boeing subsidiaries Wisk Aero, SkyGrid and Insitu, a sweeping transaction that expands Archer well beyond its air-taxi origins. Instead of concentrating primarily on electric vertical takeoff and landing aircraft, Archer is positioning itself across commercial aviation, defense systems and automated airspace management.

The deal, announced jointly by Boeing, is expected to close by the end of 2026. Completion remains subject to agreed closing conditions, including expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. Financial terms were not disclosed in the announcement.

The immediate financial addition comes from Insitu. Archer stated the profitable defense business generates over $200 million in annual revenue and operates across 35 countries. Insitu has manufactured and fielded more than 3,500 unmanned aircraft systems, with offices in the US, Australia, the UK and the UAE. Its aircraft and AI-enabled applications support intelligence, surveillance and reconnaissance missions.

That revenue addresses the capital-intensive nature of aircraft development, where certification, manufacturing and deployment take considerable time. Adding an established defense operation diversifies the company's revenue base while providing access to government customers, operational infrastructure and aircraft already used in demanding environments.

Wisk brings 16 years of hardware and test experience, having designed, built and flown six generations of eVTOL aircraft and completed more than 1,700 flight tests. Its technology includes autonomous flight controls, sensors and radar designed with civil and defense certification requirements in mind.

SkyGrid provides the ground layer, offering aircraft-agnostic traffic-management technology intended to coordinate automated aircraft and integrate them into shared airspace. This capability targets the logistical requirements of managing large fleets as commercial eVTOL and UAS operations scale from limited demonstrations to higher-volume service.

Together, Wisk, SkyGrid and Insitu contribute nearly two million flight hours. Archer expects the resulting operational data and engineering experience to strengthen ZEE, its purpose-built AI foundation model for aerospace and defense. The strategic pitch is an end-to-end physical AI system spanning aircraft, onboard autonomy, mission applications and ground-based traffic coordination.

Integrating these capabilities into certifiable products requires demonstrating system reliability, redundancy, human oversight, cybersecurity and safe behavior under unusual operating conditions. Archer will continue to face extensive FAA certification work as it pursues commercial eVTOL service.

The acquisition also builds on an existing relationship. Archer raised $215 million in equity financing in 2023, with Boeing among the investors, as Reuters reported at the time. The new transaction deepens that connection while changing its structure: Boeing will take an equity stake in Archer and become a strategic partner.

Under the collaboration and technology-sharing arrangement, Boeing will retain access to Wisk’s core autonomous-flight technology for current and future commercial and defense aircraft programs. Boeing can therefore focus investment on its core operations while preserving exposure to autonomy development through both technology access and its Archer stake.

Investor-focused Seeking Alpha characterized the announcement as transformative, reflecting the scale of Archer’s proposed shift. Archer must now integrate teams with different products, customers and regulatory pathways while protecting ongoing programs and customer relationships.

If completed as planned, the transaction gives Archer a combination of revenue-producing defense operations, autonomous-flight experience, eVTOL development and digital airspace infrastructure. The next phase requires proving that Wisk, SkyGrid, Insitu and the ZEE AI model can operate as a coherent aerospace and defense portfolio.
