Radio Frequency Generation (RFGEN) Subsystem Development and Integration (SDI) Prototype Project

On 15 September 2021, in accordance with 10 U.S. Code § 2371b, the Army Contracting Command – Orlando has awarded an Other Transaction Agreement (OTA) via the Training and Readiness Accelerator (TReX) for the Radio Frequency Generation (RFGEN) Subsystem Development and Integration (SDI) Prototype Effort.

A Request for Solutions for this effort was issued through TReX on 22 June 2020, which resulted in the submittal of 3 responses for RFGEN. The prototype project was awarded to Amherst Systems Inc – A Northrup Grumman Corporation located in Williamsville, NY. The total value of this prototype project, if all options are exercised, is $49,900,000.00.

“The objective of the RFGEN SDI prototype project is to adapt and expand previous research, development, and initial proof-of-principle prototyping conducted by NAVAIR to date. The RFGEN prototype project will design, develop, fabricate, assemble, integrate, and test variants of the initial proof-of-principle RFGEN prototype capability. Specifically, the RFGEN prototype project will develop and demonstrate a specific aircraft mission.

The Navy anticipates further development of one or more prototypes that may be required to establish IOC. If further development is required, NAVAIR 5.4 IBST will continue the development of the RFGEN SDI prototype(s) until all requirements specified by the user, resource sponsors, and stakeholders are met, and IOC is established.

The Navy anticipates conducting a low rate initial production (LRIP) of each of the RFGEN DGI variant prototypes that reach IOC. LRIP will be used to produce a small quantity set of test articles to provide for representation at Initial Operational Test and Evaluation (IOT&E). LRIP will also be used to establish an initial production base and set the stage for a gradual increase in production rate to allow for Full-Rate Production (FRP) upon completion of Operational Test and Evaluation (OT&E). The LRIP quantity will not exceed 10 percent of the total expected production, as determined by NAVY, resource sponsors, and stakeholders.

In accordance with 10 U.S.C. 2371b(f), the Navy does anticipate (upon successful completion of IOT&E and OT&E activities) production of each RFGEN SDI variant prototype may be required. This will include maintenance and sustainment support. NAVY will brief resource sponsors and stakeholders to recommend either a non-competitive, follow-on production OT or a sole-sourced FAR-based production contract. This determination will be under Government cost estimates and plan of action and milestones (POA&M).


The Naval Air Warfare Systems Command (NAVAIR) desires to further advance its capabilities in the areas of electronic threat simulation and measurement focusing specifically on advances in the areas of system concept, architecture development, and requirements definition. The overall goal is to meet the increasingly critical requirements for current and future Department of Defense (DOD) aircraft, which contain electronic combat support systems. To meet this goal, NAVAIR is developing a new simulator program called NEWEG, which consists of a single configurable set of unclassified subsystems. The set contains one Scenario Simulation and Control (SSC) subsystem, one or more DGEN subsystems, one or more Radio Frequency Generation (RFGEN) subsystems, and a Measurement and Analysis subsystem. NEWEG is currently being developed in two Blocks: A and B. The RDGEN system will be developed, demonstrated and assessed as part of Block B. The unclassified RFGEN prototype project will focus on the continued development and testing of the RFGEN subsystem.

The objective of the RFGEN prototype project is to design, develop, fabricate, assemble, integrate, and test the NEWEG RFGEN subsystem as part of a new simulate development program at the US Navy Air Station (NAS) Patuxent River, MD. Specifically, the RFGEN prototype project will develop and integrate NEWEG capabilities that will generate the RF signal with the proper emitter modulations in frequency, amplitude, time, Doppler, and phase, as directed by the Pulse Descriptor Words (PDW) from the DGEN subsystem. . The RFGEN prototype will also transmit these signals either free-space radiation or by direct-injection using RF-over-fiber devices or RF cabling to the SUT. For direct inject mode, the RFGEN prototype will translate the time of arrival, amplitude, phase, and Doppler frequency from the System Under Test (SUT) to each individual port. Additionally, the RFGEN prototype will perform pulse arbitration based on available resources and real-time calibration. Finally, the RFGEN prototype will apply calibrations to the RF command word.
