Today’s warfighter requires the same level of access to real-time, decision-quality data while in the air as they do on the battlefield. To ensure seamless multi-domain operations, SUB-U offers DO-160 flight qualified avionics and carry-on-carry-off (COCO) products and solutions, including secure IP networking solutions, high-density compute solutions, and rugged Wi-Fi access points.

Our IP networking and compute solutions provide a secure, tactical network in the sky enabling the secure processing, storage, and transport of critical unclassified and classified voice, video, and data, over commercial technologies such as Cellular, Wi-Fi, SATCOM, and MANET.

By leveraging our Software Definable Network–Appliance™ (SDN-A™) technology, the first of its kind Rugged CSfC Airborne Solution (RuCAS) enables you to deploy a single-box, complete CSfC infrastructure solution that complies with one or multiple NSA Commercial Solutions for Classified (CSfC) data in transit Capability Packages.

SUB-U solutions support vital command, control, computers, communications, cyber-defense, intelligence, surveillance, and reconnaissance (C5ISR) operations from manned and unmanned fixed and rotary-wing platforms.



The Sub U Systems Rugged Compute Airborne Solution (RuCAS) is a purpose-built appliance designed from the ground up for rotary and fixed-wing aircraft applications. The RuCAS is the first of its kind DO-160 flight qualified and meets MIL-STD-810, and MIL-STD-461. In addition to airborne applications, the RuCAS can be deployed in ground and maritime, manned, and unmanned, platforms.

The RuCAS contains seven (7) SUB-U Software Definable Network–Appliance™ (SDN-A™) modules. Each SDN-A module can be configured with one or more software based virtualized network function (VNF) or host application server virtual machine appliances.

A single RuCAS can contain every networking function required to meet one or multiple NSA Commercial Solutions for Classified (CSfC) data in transit Capability Packages. This unique capability makes the RuCAS the first “single box” complete CSfC infrastructure solution. The solution is rugged, low SWaP, and provides enterprise class performance.

The RuCAS appliance is available with traditional MIL-STD 38999 connectors for airborne and extremely rugged applications, or standard 10G Base-T RJ45 interfaces for interoperability with other COTS equipment.


SUB-U has ruggedized the Aruba AP555, developing a new environmentally robust enclosure and internal electronics to meet DO-160 flight qualification and MIL-STD-810 levels of ruggedization. The creation of the SUB-U Rugged Aruba AP555 is based on the partnership between SUB-U and Aruba, a Hewlett Packard Enterprise company.

Tactical Field Office (TFO)

Our Tactical Field Office (TFO) solutions are modular and enable users to create deployable secure wired and wireless networks, IP networking infrastructure, data centers, and signal processing solutions. They are built rugged to operate in any tactical environment based on the use of Half Rack Width (HRW), and traditional 1U and 2U appliances, as needed.
