The Army is conducting Sources Sought market research for a modernized, multi-spectral, automated test set to support field- and depot-level maintenance of Army aviation and ground night vision systems. The intended system must verify operational and performance parameters for legacy Image Intensifier devices, thermal weapon sights, fused multi-band systems such as ENVG-B, and digital augmented reality displays such as IVAS. The government seeks to identify interested parties and assess COTS/NDI electro-optical test stations against the Purchase Description for the Night Vision Device Test Set, including availability, technical maturity, trade space, and budgetary cost benchmarks, to avoid an extensive high-risk government development program. Acquisition planning is underway for a commercial five-year Firm-Fixed-Price IDIQ contract with two one-year option periods. Interested parties must complete and submit the provided NVDTS RFI Questionnaire to the listed points of contact.
