A -- PRELIMINARY SPECIFICATIONS FOR TELESCOPE POC Contracting Officer, Carol Parnell (202) 767-2372 E-MAIL: synopsis@contracts.nrl.navy.mil, synopsis@contracts.nrl.navy.mil. Special Notice 1998 Jan. 8 This special notice is for respondents to the NRL Sources Sought which was published September 18, 1997 or for any other interested parties. This telescope would be for space object tracking and astronomical viewing and would be movable. These preliminary specifications for an NRL Telescope are for planning purposes only and shall not be construed as a request for proposal (RFP), an Invitation for Bids (IFB), or as an obligation on the part of the Government to acquire any follow on capabilities. The Government does not intend, at this time, to award a contract or otherwise pay for the information provided. No entitlement or payment of direct costs or charges by the Government will arise as a result of submissions of responses. Any procurement will be separately synopsized in the Commerce Business Daily. Comment are solicited. Sent comments to: ATTN: Dr. Joe G. Foreman; Code 8001.1; Naval Center for Space Technology; 4555 Overlook Avenue SW, Washington, DC 20375. No proprietary data should be submitted.
