In the current art, users with significant computing requirements have typically depended on access to large, highly shared data centers to which they backhaul their data (e.g., images, video, or network log files) for processing. However, in many operational scenarios, the cost and latency of this backhaul can be problematic, especially when network throughput is severely limited or when the user application requires a near real-time response. In such cases, users’ ability to leverage computing power that is available “locally” (in the sense of latency, available throughput, or similar measures that are relevant to the user or mission) could substantially improve application performance while reducing mission risk.

As commercial technologies become more advanced and widely available, adversaries are rapidly developing capabilities that put our forces at risk. To counter these threats, the U.S. military is developing systems-of-systems concepts in which networks of manned and unmanned platforms, weapons, sensors, and electronic warfare systems interact over robust satellite and tactical communications links. These approaches offer flexible and powerful options to the warfighter, but the complexity introduced by the increase in the number of employment alternatives creates a battle management challenge.

Complex Defense systems, such as RADAR, communications, imaging and sensing systems rely on a wide variety of microsystems devices and materials. These diverse devices and materials typically require different substrates and different processing technologies, preventing the integration of these devices into single fabrication process flows. Thus, integration of these device technologies has historically occurred only at the chip-to-chip level, which introduces significant bandwidth and latency-related performance limitations on these systems, as well as increased size, weight, power, and packaging/assembly costs as compared to microsystems fully integrated on a single chip.

The general-purpose computer has remained the dominant computing architecture for the last 50 years, driven largely by the relentless pace of Moore’s Law. As this trajectory shows signs of slowing, however, it has become increasingly more challenging to achieve performance gains from generalized hardware, setting the stage for a resurgence in specialized architectures. Today’s specialized, application-specific integrated circuits (ASICs) — hardware customized for a specific application — offer limited flexibility and are costly to design, fabricate, and program.

DRINQS is a fundamental science program that aims to investigate a recent paradigm shift in quantum research, which maintains that periodically driving a system out of equilibrium may increase the length of time that its quantum state endures. DRINQS aims to investigate this phenomenon and demonstrate significant gains over conventional states in timekeeping, field sensing, and information processing for use in national security applications.

Over the past decade, DARPA’s investments in the advancement of Gallium Nitride (GaN) technology have helped enable the delivery of high power radio frequency (RF) signals at higher frequencies, bandwidths, and efficiencies. Today, however, a growing number of commercial and military components – from everyday smartphones to RF jammers – are generating a vast amount of RF signals, which is creating an increasingly crowded electromagnetic environment and a need to utilize higher operating frequencies – moving up to millimeter wave (mmW) frequencies More

The United States military is heavily dependent on networked communication to fulfill its missions. The wide-area network (WAN) infrastructure that supports this communication is vulnerable to a wide range of failures and cyber attacks that can severely impair connectivity and mission effectiveness at critical junctures. Examples include inadvertent or malicious misconfiguration of network devices, hardware and software failures, extended delays in Internet Protocol (IP) route convergence, denial of service (DoS) flooding attacks, and a variety of control-plane and data-plane attacks resulting from malicious code embedded within network devices.
