SOLICITATION NO: N00173-18-Q-AL02
This is a request for information (RFI) issued by the Naval Research Laboratory (NRL) for information and planning purposes only. This is neither a formal Request for Proposals (RFP) or quotes. No awards will be made from the responses to this announcement. The Government will not reimburse any costs associated with the development and submission of materials in response to this request. There is no solicitation available at this time. However, should such a requirement materialize, no basis for claims against NRL shall arise as a result of a response to this notice or NRL's use of such information as either part of our evaluation process or in developing specifications for any subsequent requirement.
Objective:
