DIU Presents: Specular MIST Prize Challenge

DIU Presents: Specular MIST Prize Challenge

Overview of the Event

The Defense Innovation Unit (DIU), in collaboration with the Department of the Navy Rapid Capabilities Office (DONRCO) and Naval Information Warfare Center Pacific, seeks to identify innovative, scalable, and cost-effective solutions to address modern maritime training and operational challenges. Traditional acquisition timelines no longer support the urgent needs of our warfighters. To maintain maritime superiority, the Specular MIST Challenge accelerates the prototyping and fielding of transformative technologies that deliver an operational advantage at speed.

A critical component of this modernization effort is the deployment of autonomous and containerized payloads to generate combat power at speed and scale. This initiative focuses on accelerating the development, prototyping, and production of a portfolio of payloads for integration onto manned and autonomous Unmanned Surface Vessels (USVs), providing adaptable, lethal, and decisive advantages in contested maritime environments.

A team of subject matter experts will evaluate applicants across a multi-phase competitive process, down-selecting companies to participate in a live At-Sea Challenge demonstration event.

Problem Statement

Current maritime training frameworks and operational capabilities often rely on rigid, distribution-limited, or cost-prohibitive payloads that lack the flexibility to scale. To enable cost-effective sensing, training emulations, and electronic warfare capabilities across autonomous platforms, the DoD requires modular payloads optimized for Size, Weight, and Power (SWaP) that feature open-system architectures and software-defined capabilities.

Submissions are open across three distinct Lines of Effort (LOEs):

• LOE 1: Threat Radar Simulators - Develop a fleet of maritime-suitable threat radar simulators to provide dynamic threat target presentations for modern training challenges. Emulators must emit complex S-band signals from a moving vessel, operate remotely, and be marinized to support future integration with autonomous USVs.
• LOE 2: Active Electronic Attack (EA) - Integrate modern active EA capabilities onboard autonomous USVs to execute autonomous electromagnetic warfare operations. Microwave Radio Frequency (RF) technology must sense, digitize, and react to the environment without operator input, featuring real-time adaptive jamming against multiple simultaneous signals.
• LOE 3: Passive Electronic Surveillance - Provide remotely operable electronic surveillance capabilities at scale to crewed and uncrewed surface platforms. Must sense and process the RF environment with remote operator input, providing state-of-the-art cybersecurity compatible with the existing Navy landing zone.

Technical Attributes

Solutions for LOE 1 & 2 should be designed with a modular, open-system architecture. A focus should be placed on real-time reprogramming and software-defined RF capabilities to deliver tunable solutions. Submissions must address the following focus areas:

• Tunable & Scalable: Demonstrate a modular open systems architecture with software-defined radio programming for maximum tunability and rapid technology insertion. Address your plan for solution availability, production capacity, and unit cost for 1, 10, 50, 100, and 300 units, beginning 6 months after Challenge completion.
• Integration: Address unmanned platform integration design, payload optimization (Size, Weight, and Power), and demonstrate the ability to account for vessel motion (roll, pitch, yaw) to ensure accurate payload pointing.
• Environmental Conditions: The solution must feature a resilient design addressing maritime conditions, elevated temperatures, and ship vibration while maintaining performance. It must also address power and thermal management to ensure efficient thermal dissipation for high-power components.
• Command and Control (C2): Detail a common C2 architecture capable of operating the primary payload and co-located systems remotely. For LOEs 1 and 2, The solution must demonstrate the ability to ingest target positioning data and automatically adjust antenna position accordingly. For LOE 3, the solution must be capable of operating with multiple layers of encryption while underway, while supporting data transfer of recorded wideband RF.

Specific Technical Requirements

The following Specifications must be met to have a viable solution.

For LOE 1: Threat Radar Simulators: 

The emulator must meet the following minimum technical specifications:

• The system must provide an Effective Radiated Power (ERP) of 50 dBW operating at a 10% duty cycle.
• The radar waveform must support a pulse width ranging from 0.5 to 55 µs, a pulse repetition frequency (PRF) between 50 and 5,000 pps, and utilize both unmodulated pulse and Linear Frequency Modulation (LFM) techniques. 
• The system must maintain a maximum harmonic level of 15 dBc and deliver a beamwidth capable of providing an instantaneous azimuth coverage of at least 10°, complete with elevation pointing capabilities.

For LOE 2: Active Electronic Attack (EA):

The system must demonstrate the ability to operate effectively in a contested electronic warfare environment. It must simultaneously detect and discern multiple discrete queued signals and provide adaptive jamming suppression in real-time without operator intervention.

For LOE 3: Passive Electronic Surveillance: 

The system must be meet the following minimum technical specifications:

• The system must feature radio frequency (RF) environmental sensing capabilities that encompass, at a minimum, the VHF and UHF bands. It must include subsystems providing position and timing, and deliver a total instantaneous bandwidth of at least 50 MHz. Additionally, the system architecture must be fully capable of hosting and operating government-provided software.
• Submissions will be judged by the degree to which they comply with the NSA’s CSfC requirements for data at rest and data in transit, frequency range coverage beyond the minimum specified here, and innovative design decisions leading to cost savings in production or for technological refresh.

Competitive Process & Evaluation Criteria

The challenge is structured into three progressive evaluation phases:

Phase 1: Proposal & Down-Select

-White Paper & Pitch Deck

Phase 2: At-Sea Live Demo

-Live demo at Southern California Event with Direct End-User Testing

Phase 3: Post-Demo Pathway

-Maturation Prizes and potential for Follow-on OTA prototype contract / Procurement

Phase 1: Proposal Evaluation & Down Selection

Initial evaluation of written submissions to select viable commercial technologies for live demonstration. Vendors selected to advance receive up to $250,000 to fund participation.

• Technical Viability & Alignment: Degree to which the solution meets the Technical Capabilities and individual LOE requirements.
• Team & Company Viability: Demonstrated capability, current production rates, and corporate expertise to successfully develop, deliver, and sustain the solution.
• Cost & Scalability: Feasibility of proposed pricing ranges across varying production volumes and lifecycle maintenance.
• Quality of Proposal: Clear, thorough explanation of how the technology fills current capability gaps and enhances operational effectiveness within the chosen LOE.

Phase 2: At-Sea Challenge Live Demonstration & Pitch Evaluation

Hands-on operational assessment under realistic conditions in Southern California, evaluated by a designated team of DoW end users. Down-selection to Phase 3 yields up to $1,000,000 per selected company and potential for follow-on prototype or production contract. Evaluated on Phase 1 criteria plus:

• Operational Effectiveness: Proven resilience and performance of the hardware/software when exposed to highly dynamic EM environment and maritime weather conditions.
