Title: AN/BPS-15 RADAR MAST THERMAL SPRAY RESTORATION SERVICES

Place of Performance: Vendor Facility - CONUS

Period of Performance: From 11 AUG 2023 to 27 DEC 2023; contingent on Award 31 JUL 2023

1. BACKGROUND

1.1 The Trident Refit Facility Bangor (TRF-B) Radar Depot performs restoration of SSN688 Class, SSN 688I Class, and SSBN 726 Class variants of the AN/BPS-15 radar mast for the US Navy.

During restoration of radar masts, the outer surfaces of each radar mast requires surface finish restoration using NAVSEA certified thermal spray deposition processes and facilities. Reference

2.1, Enclosure (2), paragraph 1 specifies refurbishment of the outer surfaces of the three variants of the AN/BPS-15 radar mast using thermal spray deposition processes identified of Reference

2.2.

1.2 Radar masts are used in critical end-use applications and as such are subject to additional process controls as and traceability requirements by NAVSEA for SUBSAFE and Level 1 materials.

Radar masts must maintain their SUBSAFE/Level 1 certifications at all time, and as such, TRF-

B, the NAVSEA qualified “SUBSAFE Certifying Activity”, will oversight the repair process required by contract for SUBSAFE/Level 1 work performed by contractors not previously certified to perform SUBSAFE work by NAVSEA.

1.3 Two AN/BPS-15 radar masts, one SSBN 726 Class variant and one SSN 688I Class variant, require refurbishment by thermal spray. The SSBN 726 Class AN/BPS-15 radar masts described in paragraph 5.3.1 requires thermal spray repairs of the surfaces IAW sheet 5 of 5 from Enclosure

3 of Reference 2.1. The SSN 688I Class AN/BPS-15 radar masts described in paragraph 5.3.2 requires thermal spray repairs of the surfaces IAW sheet 3 of 5 from Enclosure 3 of Reference

2.1. Each radar mast is listed in paragraph 11.2.3 in order of priority, critical needs listed first.
