Integrated Appliances/Solutions ​

By leveraging best-of-breed technologies, our integrated appliances and solutions solve challenging IP networking and communications problems for unique applications requiring stringent size, weight, and power constraints.

Some applications require solutions that go beyond current off-the-shelf offerings, and we are always up for the challenge. Our integrated solutions directly result from development efforts where customer requirements and/or funding were provided, to support the customers’ unique applications and technical requirements. They often combine our hardware and software solutions with those of our industry partners such as Aruba, Cisco, Epiq Solutions, RIVA Networks, JPS Interoperability, and several others.

We leverage our 13 years of history and experience designing and building solutions from the PCB and/or firmware up to deliver tightly integrated solutions to meet the most stringent size, weight, power, performance, and security specifications.

Our integrated solutions address a myriad of applications, including:

We design our solutions from the PCB and firmware up, which allows us to deliver custom, integrated solutions to meet your exact requirements. We enjoy product development and pride ourselves on offering the most forward-leaning technology solutions.

Aruba R-AP 555

The creation of the SUB-U Rugged Aruba AP 555 is based on a partnership between SUB-U and Aruba, a Hewlett Packard Enterprise company. SUB-U has ruggedized the Aruba AP 555 802.11ax Wi-Fi 6 Access Point by developing a new environmentally robust enclosure, and hardened internal electronics, to meet DO-160 flight qualification and MIL-STD-810 levels of ruggedization.


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 that contains (7) Intel® servers, that are interconnecting internally over multiple 10-gigabit interfaces. The RuCAS is the ultimate tactical cloud compute appliance with up to 112 cores, 224 threads, 866GB of RAM, 56TB of NVME storage; designed from scratch to support extremely harsh operating environments. 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.

Contains (7) Intel® processors, up to Xeon® D 16 core/32 thread CPUs, each with 128GB of RAM, NVME drives, and (8) 10G 10Gbase T interfaces per each of the (7) processor
