The Government is currently soliciting whitepapers only (not formal proposals) for the Air Force Research Laboratory's Enterprise Prototype Initiative Consortium (EPIC) Other Transaction Agreement for Prototype, which aims to rapidly prototype capabilities across all technology areas of interest to sustain U.S. military technological advantage. The anticipated award is an Indefinite Delivery Vehicle (IDV) with an unlimited ceiling, a project ordering period of 120 months, and project performance allowed up to 24 months after the ordering end date. Project Level Orders will be awarded on a firm-fixed-price basis, and the successful offeror must have an accounting system capable of tracking Government funds. Successful completion of orders may lead to sole-source follow-on production contracts or other transactions. Foreign participation is closed at both the OT lead and performer levels, and overall effort may allow awards up to TS/SCI classification.
