NAVAIR Lakehurst intends to award a sole source IDIQ contract to EWA Government Systems, Inc (EWA-GSI), Mt. Laurel, NJ to continue the Research and Development (R&D) effort to design, integrate, test and deliver software for its Closed Loop Passive Electronically Scanned Array Simulator (CLPS), Advanced Anti-Aircraft Threat Simulator (AATS) and Advanced Radar Threat Simulator Version 1 (ARTS-V1). The CLPS, AATS and ARTS-V1 simulators will address the need to properly assess the capabilities of on-going and future Department of Defense (DoD) Electronic Warfare (EW) programs in the complex Radio Frequency (RF) environment at the DoD testing ranges. The system software under development will utilize and modify the CLPS, AATS and ARTS-V1 system software currently under development by EWA-GSI. An RFI N68335-19-RFI-0041 was previously issued on 7 November 2018 under a PSC code of AC64 and a NAICS code of 541715 to request information on potential contractors that could provide the above R&D software design and systems engineering services utilizing the AATS system software. As a result of both that RFI and further analysis, the Government will pursue continued development of the software with Electronic Warfare Associates Government Systems, Inc. (EWA-GSI). The PSC code for this acquisition is AC64 and the NAICS code is 541715. The Navy intends to procure the above on a cost plus fixed fee basis. The period of performance is from 2/1/2019 to 2/1/2021. The statutory authority for other than full and open competition is 10 U.S.C. 2304(c)(1), as implemented by FAR 6.302-1, "only one responsible source and no other supplies or services will satisfy agency requirements." The initial development of the software has already been conducted by Electronic Warfare Associates Government Systems, Inc. (EWA-GSI). The system software is based on the architecture of the AATS system under development by EWA and no other type of system software for simulators is utilized. Further only EWA-GSI has the necessary experience on threat simulator systems representing the AATS, CLPS and ARTS-V1 threat. This notice of intent is not a request for competitive proposals.
