TTTECH North America has been selected by the U.S. Army to provide advanced Time-Sensitive Networking (TSN) solutions for its High Accuracy Detection and Exploitation System (HADES) aerial intelligence, surveillance, and reconnaissance (ISR) program. This milestone highlights TTTECH’s continued competence in providing cutting-edge, MOSA-compliant, data networking solutions for mission systems as well as integrated, modular avionics (IMA) for aerospace and defense applications.

The HADES program will overhaul U.S. government-furnished Bombardier Global 6500 jets with advanced, deep sensing capabilities for multi-domain ISR operations at speeds, ranges, and altitudes not previously achievable by the U.S. Army’s retiring turboprop aircraft fleet. The open architecture digital backbone network will enable rapid upgradeability, reconfigurability, and cost-effective lifecycle management of mission system capabilities. Open system design leveraging commercial technology will accelerate the Army’s plan to reuse qualified, modular mission capabilities while being interoperable across programs.

Under this contract award, TTTECH will supply a 10 Gigabit TSN network platform composed of switch and end point products complying with the recently released IEEE 802.1DP TSN aerospace profile, along with industry leading network scheduling and configuration tools and software. TTTECH’s comprehensive, DAL A certifiable Deterministic Ethernet portfolio — spanning switches, end points, that support standard Ethernet, ARINC 664 part 7, TSN and TTEthernet — has been widely deployed and continues to set the standard for fault-tolerant, high-performance network platforms in safety- and mission-critical environments.

“This award reflects our commitment to delivering innovative, network platform solutions that enable secure, highspeed connectivity for upgradeable mission-critical systems,” said Alvaro Soares, Director of Products and Customer Programs, TTTECH North America. “We look forward to contributing to the Army’s vision for a future-ready digital backbone on the HADES program and beyond.”

Why TSN Matters for Defense Modernization

Time Sensitive Networking (TSN) is rapidly being adopted as a backbone standard for next generation aerospace and defense systems. TSN ensures reliable, low-latency data delivery across complex platforms, supporting real-time mission systems and advanced sensor integration.

“Enhancing the capabilities of the HADES digital backbone is central to our ability to integrate sensors, share data, and act in real time across airborne ISR platforms. TTTECH’s technology and collaborative approach with our industry partners are enabling a robust, scalable, and MOSA-aligned foundation that accelerates capability insertion,” stated Jeffrey Jablonski, U.S. Army HADES Program Lead, PEO Aviation.

TTTECH-furnished TSN solutions will be incorporated into SOSATM-conformant 3U-VPX based Nodal Access Units (NAUs) and TSN switch Line Replaceable Units (LRUs) provided by North Atlantic Industries (NAI), a longstanding technology partner of TTTECH. These integrations include NAI’s modular endpoint and switch platforms designed and qualified for rugged aerospace use. The U.S. Army also chose DDC-I Deos, a DO-178 Design Assurance Level (DAL-A)-certified and FACE® conformant real-time operating system (RTOS), to enable the HADES digital backbone. Deos delivers MOSA aligned, timing deterministic performance for mission-critical processing and software applications.
