Busting the myths of COTS devices in military applicationsStory
April 26, 2022
The benefits of using commercial off-the-shelf (COTS) components and systems for the military arena are clear, with the major points being lower cost and greater availability. Moreover, the modern-day ability to modify and ruggedize these parts is improving the entire landscape of military embedded electronics technology.
Military-qualified systems and components are notoriously costly due to rigorous testing requirements and strict compliance standards. Any changes in the technology will typically require a complete requalification of the device.
Commercial off-the-shelf (COTS) components have been around for decades, but recent technology advancements, digital transformation efforts, and the supply changes prompted by the pandemic have reinvigorated the industry. These factors have also driven home the point that COTS systems and components are essential to military technology. While not removing all of the expense and complex processes, modified COTS systems offer many benefits for cost effective and faster delivery.
As the name implies, COTS devices were not specifically designed for military purposes. However, when integrated correctly, COTS components can perform as the equal of some of the most sophisticated military applications available; can be sourced in less time for lower cost; and can help design teams achieve size, weight, and power (SWaP) requirements. Benefits of using COTS systems and components include:
- Reduction in costs
- Diversification of supply chain
- Flexibility in meeting design challenges
- Ability to meet SWaP requirements
The challenges of a diversified supply chain
The need to diversify the supply chain for both military and commercial applications has become critical in the last several years due to the effects of COVID-19 and the geopolitical situation with China. China’s impact on the electronic-component supply chain has been enormous, because of both the detrimental effect of COVID-19 on China’s manufacturing sector and the need to remove Chinese content from critical U.S. defense systems due to perceived threats to U.S. defense technology. Compound these two factors with burdensome tariffs, a lack of truck drivers and warehouse workers, a shortage of shipping containers, and increased energy costs – all of these factors have contributed to the current and ongoing supply-chain disaster.
There is also a misconception that the COTS supply chain cannot deliver on the unique needs of the military, including highly advanced and customized avionics hardware that meets ruggedization standards. But this is not the case in today’s ecosystem, as many providers can customize COTS components to meet the most advanced military requirements and provide the ruggedization that other types of customers – including those in manufacturing and other nonmilitary markets – seek.
With the entire world and nearly every industry experiencing shipping delays, leveraging COTS components to diversify a supply chain offers a significant benefit. But to achieve this, many of the components that are required to deliver a COTS solution need to be sourced in North America or with more reliable manufacturing sources. We can see this trend to-ward the desire for enhanced capability, for example, in the semiconductor industry where many new semiconductor plants are either expanding their U.S. presence or are moving entire fabs into the U.S.
Lower costs and greater availability
The biggest benefits that have emerged from using COTS components are overall lower costs, greater availability, and faster delivery. Non-military-grade technologies are always going to be less expensive, with more vendor choice But the assumption that the lower cost associated with COTS components is synonymous with lower quality is simply not true anymore, with the reliability of commercial-grade components and systems increasing greatly.
Another hurdle is availability: Because of the strict regulatory requirements in the defense industry, availability of military-grade components is often limited. Developing new technology in the defense industry is incredibly time-consuming so the volume of components isn’t always there, while refurbishing or upgrading old components includes a lot of red tape and a lot of time. Therefore, turning to COTS components is sometimes necessary to navigate parts availability.
Military applications used to be the pinnacle of innovation and quality, but in many cases, innovation in other industries has eliminated the justification for expensive military-grade equipment. Some of the most advanced systems and technology used by military customers are built using mostly COTS components, whereas in the past these systems were primarily developed by defense prime contractors over many years and at twice the cost.
In the past, the knock on COTS components was usually that COTS products tended to be behind the technology curve. However, with the advent of gaming, augmented reality, robotics, and supercomputing, the commercial and industrial markets now lead the defense market in sophistication level and reduced SWaP and are more applicable as COTS components.
Military-grade systems are notorious for proprietary hardware packages with locked-down interfaces that make them difficult to integrate into existing systems. A major benefit of using COTS systems is they are almost always easier to integrate into customer’s existing system or can be engineered to be both hardware and software agnostic. Enhanced interoperability also correlates with the increase in flexibility that military customers have when designing systems using COTS components. (Figure 1.)

Importance of software
The ability to manage COTS hardware and create modified solutions is now much easier because of more advanced software capabilities. Additionally, it’s important to understand that sometimes having full government rights and access to information might not need to be the ultimate goal: A design team that has clearly defined requirements and an understanding of the purpose of what it is buying for can put less emphasis on access to proprietary information.
In fact, limiting what systems and capabilities really need full access to proprietary information can make it easier to hire and work with the most innovative technology vendors, without the need for limits (like security clearances) on the pool of people considered to create new designs.
Modified COTS = MOTS
Ultimately, it isn’t just about the advancements in commercially available hardware and software that make COTS components a more viable option. It’s also about the possibility of creating modified COTS (MOTS) products. Such MOTS parts can provide the best of both worlds. MOTS products are customized to meet the needs of the customer, as they use COTS devices as a starting point. They include all of the benefits mentioned of COTS devices but can then be customized and built to meet all the ruggedization and other needs associated with the military. Some of the most advanced hardware currently being used in the military are MOTS parts, including computers, displays, tablets, storage servers, and surveillance systems.
Ultimately, the use of COTS products is here to stay; frankly, they are needed more than ever as the industry grapples with ongoing pandemic-related supply-chain issues. The good news is that the widespread use of COTS components and digital transformation across the world has made world-class commercially available technology readily accessible. Using COTS devices was key to the quick rollout of emerging technologies such as Wi-Fi, LTE, and smartphones in the military. Going forward, COTS and MOTS will be key to future protocols such as enhanced 5G/6G and advanced cybersecurity.
