B-2 Low Observable Signature & Supportability Modifications (LOSSM)

The Department of the Air Force Materiel Command Lifecycle Management Center is seeking contractors to develop an improved point inspection system for B-2 aircraft as part of the Low Observable Signature & Supportability Modifications (LOSSM) Tier I Tool program. The procurement involves designing and delivering systems that can measure Radar Cross Section (RCS) signature defects using advanced probe and integrated vector network analyzer (VNA) technologies to replace existing stand-alone equipment. Key requirements include integrating miniaturized VNAs to eliminate existing RF cables that induce measurement errors, meeting Class I, Division 2 electrical safety standards per the National Electric Code, ensuring the system can be transported and operated by a single user, and executing radio frequency point inspections rather than zonal or visual inspections. Contractor responsibilities encompass analysis, design evaluation, development, production, installation, integration, testing, training support, database generation, and sustainment activities. Prospective vendors must submit a 15-page unclassified technical capabilities statement addressing probe technologies, equipment consolidation, calibration methodologies, security approaches, and measurement error characteristics to alana.williams.1@us.af.mil by 4:00 p.m. EST on January 31, 2026, and must be registered in the System for Award Management (SAM).
