Azimuth Gearbox Assembly Procurement

Description

AFLCMC/ESGK-R hereby awards on a competitive (Full and Open) basis, a Definitive Contract for the procurement of procurement of two (2) azimuth gearbox spares. GLOBUS-X relies on worn gearboxes (originally manufactured in 1993) with only one (1) spare. Over the course of program history, the X-Band has experienced a catastrophic failure of one (1) azimuth gearbox impacting mission execution, most recently 2018. The X-Band radar rests on a unique azimuth bull gear and associated azimuth bearing assembly that permits the radar to be rotated in azimuth direction. The azimuth gearbox also includes a unique pinon gear that aligns with the bull gear to result in slower rotation but greater torque at the bull gear's output. The operating conditions of this gearbox are specific to this system with no known compatibility with any existing or future program/system. The United States Air Force Life Cycle Management Center (AFLCMC) has a requirement as a part of its ongoing sustainment of the GLOBUS System of Systems. To ensure continued operational readiness of the critical GLOBUS-X radar system, this requirement is for the procurement of two (2) azimuth gearbox spares designed as direct form, fit, and function replacement for the current aging units. These custom gearboxes must precisely adhere to system specific mechanical and electrical specifications outlined in the AZ Gear Reducer Graham Sesia P/N QPP036M-U2-280 (280.42:1), RTX AZ Mod Kit drawing number D2220940, and associated drawings. Full technical specifications are detailed within the FSSM&I X-Band Pedestal Servo System Modernization document B2270320. This acquisition will be awarded to Symbrium, Inc. (Cage Code 7ELM3). The period of performance is 56 weeks ARO. The authority for this requirement is RFO 6.101
