5/7/18 The solicitation closing date has been extended to June 7, 2018. Additional drawings are available a will be sent upon request through the AMRDEC website. A correction has been made to Section 3.3 of the attached PWS. See Attachment 1 PWS S Band Lewis Scanner AMENDED. The Army Contracting Command, Aberdeen Proving Ground, Division E, Tobyhanna Branch, Tobyhanna Army Depot (TYAD), Tobyhanna, PA 18466 intends to solicit and award a contract for overhaul of the S-Band Lewis Scanner Azimuth Antenna PN: 583Z5001MC-1 and S-Band Lewis Scanner Elevation Antenna PN: 583Z5001MC-3 antenna assemblies that are part of the AN/MPS-T1(V) Threat Simulator radar system. Requirements include hardware and electrical functionality as well as mechanical repair, finishing and RF pattern testing. Each antenna assembly is comprised of five sections: A. Scanner (PN: 583Z5024MC-1): Contains a rotary joint, P/N 2176, that connects to WR284 waveguide. B. Scanner Cone (PN 583Z5014-1): Comprised of an input parallel plate waveguide section containing an input for the scanner and RF mirror located in the middle of section that directs RF energy as the scanner rotates. C. Geodesic Lens (PN 583Z5010-1): This is a parallel plate waveguide section containing a sunken curved waveguide path to enhance RF energy direction for beamforming. D. Asymmetrical Horn (PN 583Z5021-1): This is the output parallel plate waveguide section for directing RF energy onto a reflector. E. Reflector (PN 583Z5011-1): This is the final output of antenna system. The reflector is approximately 2 FT x 16 FT. The antennas operate in the 2.9 GHz to 3.1 GHz frequency range and the RF beam is electro-mechanically scanned from (-) 10 degrees to (+) 10 degrees without moving the radar system platform. Performance includes the mechanical repair and finishing of the antennas to include iridite coating and epoxy primer. When mechanical repairs and primer coatings are completed the sections shall be assembled as an antenna assembly and electrical performance verified by measuring antenna patterns. If the antenna assemblies do not initially pass electrical performance, the vendor shall make any alignments necessary for them to pass specification. The resultant contract will include two separate contract line items (CLINS) and two (2) Test and Evaluation (T&E) reports. The T&E portion of any resultant contract will be on a Firm-Fixed Price CLIN and the repairs will be on a Time and Materials CLIN. The first T&E report is for the two (2) scanner cones (PN: 583Z5001MC-1 & PN: 583Z5001MC-3). The second T&E report is for the two (2) geodesic lenses (PN 583Z5010-1), two (2) asymmetrical horns (PN 583Z5021-1) and two (2) reflectors (PN 583Z5011-1). The Government will review the first T&E report for the two (2) scanner cones and issue or not issue a notice to proceed ("NTP"). Upon completion of repairs the Government will inspect the scanner cones. Results of the Government evaluation will determine if the Government will issue or not issue a 2nd "NTP" for repair of the remaining equipment. Upon completion of repairs the proposed Antenna Pattern testing will be conducted and test results will be provided documenting the measurement of, antenna gain, beamwidth, sidelobe (To include comma lobes or shoulders), scan angle, polarization and antenna pattern(s) for the S-Band Lewis Scanner Antennas. Government Furnished Property (GFP) required for the buildup of the S-Band Lewis Scanner Antenna Assemblies will be provided and all GFP shall be returned to TYAD after completion of work. Completion and Final Acceptance of all requirements shall be no later than 240 Days after date of contract award. Deliverables are FOB Destination to Tobyhanna Army Depot, Tobyhanna, PA 18466.
