OBJECTIVE: Develop waveforms designed to address gaps in current tactical waveform technology. These waveforms shall include high-capacity throughput and Low-probability-of-Detection/Identification/Tracking/(LPx) features to counter rapidly evolving threats with an open architecture digital interface to minimize application integration risks, and challenges. These waveforms should be power efficient and portable across multiple hardware instantiations for beyond line of sight and omni-directional line of sight (threshold) and directional communications (objective).

DESCRIPTION: Current Radio Frequency (RF) communications systems have become common in both infantry dismounted and mounted operations used to communicate beyond line of sight (BLOS) and line of sight (LOS) with maritime vessels, air assets, ground command and control, and with adjacent units. Trusted secure communications are required to ensure elements are employed effectively. Having the ability to communicate without being detected, intercepted, or tracked is highly desired to protect a high-risk element that may be compromised by threat electronic warfare assets. Ground elements need to pass authenticated mission critical data and voice traffic to share situational awareness data, command and control, targeting data, and voice traffic. It is desirable for the new waveforms to defeat current and anticipated threat systems. High-data throughput waveforms are designed to transmit large volumes of data at near-real-time to real-time rates within line of sight and are essential to support combat operations.

Waveforms will be designed to run on the Field Programmable Gate Array (FPGA) environment. Digital data interface will leverage IEEE standards that are easier to interface with (e.g., Internet Protocol). The waveforms developed should not interfere with other aircraft subsystems inside the aircraft or other systems over RF. Existing systems are based on hardware designs that operate a single waveform and any updates/modernization requires replacing hardware. The design should enable adding updates to existing waveforms or completely new waveforms into the system without requiring new hardware or being returned to the factory/depot for the update.

Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by 32 U.S.C. § 2004.20 et seq., National Industrial Security Program Executive agent and Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA) formerly Defense Security Service (DSS). The selected contractor must be able to acquire and maintain at least a secret level facility and Personnel Security Clearances. This will allow contractor personnel to perform on advanced phases of this project as set forth by DCSA and NAVAIR in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material during the advanced phases of this contract IAW the National Industrial Security Program Operating Manual (NISPOM), which can be found at Title 32, Part 2004.20 of the Code of Federal Regulations.

PHASE I: Design and develop a framework that supports development of FPGA hosted waveforms. Provide a detailed description of the system architecture and necessary input and output interfaces. Identify key components necessary for operation. The Phase I effort will include prototype plans to be developed under Phase II.

PHASE II: Build, test, and validate a prototype waveform that successfully defeats realistic threat vectors and demonstrate the prototype operating in a relevant environment. Identify code framework that allows for easiest integration in a modeling and simulation environment (Threshold) and an operational type of system (Objective). Develop an implementation plan. At the conclusion of Phase I NAWCAD will coordinate with Fleet Users and Operational Testers to designate a suitable threat vector(s) against which the waveform will be evaluated. Demonstrate the waveform passing data two-way using government selected software suites (e.g., ATAK). Produce and deliver a final Technical Data Package (TDP) that includes system and subcomponent specifications, interface descriptions and definitions, and operating instructions/procedures for the prototype. Prepare the prototype for transition to deployment.

A representative operational scenario will be defined for Phase II in the appropriate classified environment. Please see note in Description section. Joint Interoperability tests will be planned and coordinated for the end of Phase II demonstrations.

Work in Phase II may become classified. Please see note in Description paragraph.

PHASE III DUAL USE APPLICATIONS: Conduct government verification and validations, including the design development conducted in the initial phases to show the technical feasibility of the idea and lay the groundwork for the demonstration in the next phase. Demonstrate that the design is technically and operationally feasible with test points that will validate the waveform and lay the groundwork for transitioning to appropriate laboratories and/or platforms to bring the capability to the Fleet. The system will be assessed against existing systems operating the same waveform(s) to verify they meet the appropriate interoperability standards as the existing baseline systems do with the applicable Navy, Joint Tactical Networking Center (JTNC), and Defense Information Systems Agency (DISA) tests.

Software Defined Radios (SDR) are widely in use in DoD and commercial communications systems, as are efforts to develop Open Systems Architecture (OSA) designs. These software-driven designs support rapid updates and incorporation of new technologies to enable addition of future requirements and to grow to address evolving threats.

Topic Q & A

5/28/24  Q. Can the government provide a description of the existing hardware platform that the waveforms are expected to be hosted on? Additionally, should the Phase I proposal solely focus on design and development of a framework/architecture for developing FPGA hosted waveforms, or should it include details regarding the waveforms that will be hosted and how they meet the identified objectives?
   A. Currently DoD and our Allied and Coalition partners are relying on Link 16 Tactical Data Link (TDL) that can currently share 114 kb (being updated to 1.1 Mb) at 300 nmi with hundreds of line of sight users and for sending Intelligence Surveillance and Reconnaissance (ISR) data we have Bandwidth Efficient Common Data Link (BE-CDL) that can share 200 kb to 274 Mb point-to-point. Tactical communications need to be secure (eg NSA Type 1), robust (ability to protect against current and predicted threats), and be adaptable to adjust for evolving requirements. We are interested in new ideas that could help us achieve the types of objectives DoD had when we started the Joint Tactical Radio System (JTRS) program a few decades back but were not able to achieve with the technology available at the time.
04/26/24  Q. Is the contractor responsible for developing or providing waveforms? Or is the solicitation asking for a platform that can serve as a reconfigurable transceiver for Government-provided waveforms?
   A. We are open to hear any of the contractors ideas and see what they have to bring to the table that could help Naval Aviation tactical communications capabilities.
