Sigma Defense Acquires Aries Defense to Expand CJADC2 and Tactical ISR Capabilities

Oct 20, 2025
Sigma Defense has acquired Aries Defense to strengthen its tactical edge ISR and CJADC2 capabilities, integrating Aries’ sensor and video systems with Sigma’s Olympus ecosystem.

Sigma Defense has acquired Aries Defense to enhance its tactical edge ISR and CJADC2 capabilities, announced in a press release. Aries Defense, founded in 2017, specializes in integrating tactical video and sensor data from UAVs and unattended systems to support real-time situational awareness.

The acquisition integrates Aries Defense’s fielded ISR products, including OverWatch, CheckPoints, Recon V OverWatch, and NEOS, into Sigma Defense’s Olympus ecosystem. Olympus is a DevSecOps-enabled platform designed for data fusion, orchestration, and multi-domain information sharing across the joint force.

By combining Aries Defense’s edge ISR networking and interoperability tools with the Olympus platform, Sigma Defense aims to deliver scalable UAV and sensor operations and persistent situational awareness in denied or degraded environments. Aries Defense’s solutions are already deployed under U.S. Marine Corps programs of record, supporting rapid operational deployment.

Sigma Defense stated that the acquisition strengthens its ability to provide secure, real-time ISR video and sensor data sharing across CJADC2 systems, improving interoperability and decision-making at the tactical edge.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
