Elevation Gearbox Assembly Procurement

The GLOBUS Program is a bi-national collaborative effort, supporting critical radar and communications systems with unique operational requirements and is hosted at Outside Continental United States (OCONUS) location. The GLOBUS System of Systems consists of an S-Band (GLOBUS-S) phased array radar, an X-Band (GLOBUS-X) dish radar, an Integrated System Controller (ISC) computer system, and a Mission Communication Suite (MCS) which was fielded in 2023. The United States Air Force, through AFMC, is responsible for the procurement of capital equipment at the operational site, sustainment (to include spares), Urgent/Emergency Depot Level Maintenance, and oversight; the Host Nation Government is responsible for operating the system and any organizational level maintenance.

This acquisition represents a mission-critical investment to mitigate risk of a catastrophic failure of a GLOBUS-X Band elevation gearbox (s). This acquisition will be for the procurement of two (2) elevation gearbox spares. GLOBUS-X, today, relies on worn gearboxes - originally manufactured in 1993 - with limited spares. There is one (1) elevation gearbox at site. The unique operating conditions and system specific design of the Elevation gearboxes render both gear boxes incompatible with any other existing or planned programs. The uniqueness and non-existence of like items, highlighting the necessity for dedicated spares.
