What must an electronics service provider for the defense industry be capable of?
Electronics are a central component of modern military systems. Sensor technology, communication systems, control units, autonomous platforms, and electronic countermeasures are based on highly integrated hardware and software. Companies working as development partners for such systems must therefore deliver significantly more than classic embedded development. In addition to regulatory frameworks such as the International Traffic in Arms Regulations (ITAR) or the Export Administration Regulations (EAR) primarily focus on core technical competencies.
Embedded Systems in Defense – Special Characteristics
From a technical perspective, three fundamental development directions can be identified, covering almost all modern military electronics systems: classic microcontroller systems, high-performance embedded processor platforms, and FPGA or SoC-based signal processing systems. An electronics partner must master all three areas because they almost always occur together in real-world systems.
Microcontroller
The first thrust is classic microcontroller technology. It forms the basis for control units and interfaces in many military platforms. Typically, these systems are based on microcontroller platforms from European manufacturers such as Infineon Technologies or STMicroelectronics. Their tasks range from measurement, control, and regulation functions to gateway and communication functions between various subsystems. In vehicle platforms, sensor systems, weapon systems, or stationary installations, such control units might handle the acquisition of physical measured values, the control of actuators, or the coordination of multiple bus systems, for example.
These systems play an important role, especially in military applications, because they ensure determinism. The real-time capable Microcontroller can, for example, for the implementation of MIL 884, far more likely to serve as diagnostic and computing-oriented processors. Many safety-relevant operations – such as actuator control, system state monitoring, or the management of energy flows – run on microcontroller platforms. Manufacturers develop drivers themselves, especially in the avionics or ground-to-air context. COTS platforms like the STM32 HAL or Infineon DAvE are rarer.
General Purpose and Application Processors
The second thrust concerns more powerful embedded processor platforms. Here, classic multi-core processors are used to process larger amounts of data or map more complex software functions. Such platforms are required, for example, for audio and video systems, diagnostic functions, data aggregation, or human-machine interfaces.
In military systems, these platforms often function as integration nodes. They collect data from various sensors, process information, and provide interfaces for further subsystems. Examples include evaluation systems for camera data, analysis platforms for communication data, or diagnostic modules for complex vehicle or aircraft systems.
The challenge here lies less in the individual software module and more in the integration of complex software stacks. Operating systems, communication protocols, middleware, and application software must work together reliably. At the same time, regulatory requirements must be taken into account, for example, when using cryptographic functions or open-source software components.
FPGA and SoC Platforms
The third technical thrust concerns FPGA and SoC platforms. This area is particularly relevant when extremely short response times or very high data rates need to be processed. Modern platforms combine classic processors with programmable logic based on lookup tables (LUTs). This allows for the construction of highly parallel data processing structures.
Such systems are used, for example, in radar and sensor systems, but also in electronic warfare applications like jamming or signal intelligence. They also play a role in cryptographic communication systems, in the processing of high-resolution video data, or in complex high-frequency signal processing.
A typical scenario involves processing analog sensor signals, which are first digitized and then evaluated in FPGA logic with extremely low latency. In target systems or guided missiles, this can involve control functions in the microsecond range, for example. Similar requirements arise in radar or communication systems, where data streams must be analyzed directly at the bitstream level.
The development of such platforms also typically requires software work to integrate FPGA design and high-speed digital design with operating systems. Of particular importance is the collaboration between FPGA logic and memory buffers, as well as AXI or AMBA connectivity. Signal processing blocks in FPGA deliver data that is subsequently evaluated, stored, or further processed by software.
Hardware and Robustness Requirements
In addition to these three technological pillars, the physical robustness of the hardware represents another central challenge. Military electronics must function under very different environmental conditions. For example, systems can be deployed in maritime environments with saltwater exposure, but equally in desert regions or the tundra.
These operating conditions lead to high demands on thermal design, mechanical stability, and material selection. Electronic designs must handle high power densities while enabling compact construction. Development processes are therefore often based on military standards such as MIL-PRF-31032 for military printed circuit boards or MIL-STD-810 for environmental and stress tests. We have compiled a whole list of requirements and best practices in our hub.
Software Specifications
From a software perspective, defense projects also differ significantly from classic embedded projects. The focus is less on individual software modules and more on the integration of complex overall systems. Developers must understand multiple levels simultaneously—from the hardware platform and FPGA logic to operating systems and communication protocols.
A crucial factor in this is deterministic real-time behavior. Many military applications require exactly predictable reaction times. Systems must therefore be designed so that scheduling strategies, task management, and data paths are clearly defined, and time-critical processes are reliably adhered to. Manufacturers therefore often choose COTS operating systems such as QNX or PikeOS.
In addition, specialized functions, such as cryptographic modules or complex communication stacks, are integrated. At the same time, regulatory requirements must be taken into account, for example in dealing with open-source software or technologies relevant to export control.
Conclusion
The sum of these requirements shows that electronics development for the defense industry goes far beyond classic embedded programming. Experienced developers and system architects who can consider hardware, software, and system integration together are in demand. Military projects require individuals with an architectural and integrative understanding – engineers who can interpret complex system requirements, define platforms, and connect multiple technologies.
An electronics partner who wants to operate in this environment must therefore possess both technical depth and a systems understanding. Only the combination of microcontroller systems, powerful embedded processors, and FPGA-based signal processing systems makes it possible to meet the technological requirements of modern defense systems.
