Defence is undertaking major reforms in an effort to deliver through life support savings in materiel sustainment. The integration of Health and Usage Monitoring Systems (HUMS) into land platforms is an area that promises wide ranging benefits including increased platform availability and efficiencies in fleet management. Land Engineering Agency (LEA) has embarked on a program of work designed to prove that employing HUMS on land platforms will deliver improvements in the management of land materiel. To validate that HUMS is a viable concept, the platform Original Equipment Manufacturers (OEMs) were contracted to each design and fit HUMS to four of their in service platforms. These vehicles were operated routinely and the HUMS data integrated with Defence’s Military Integrated Logistics Information System (MILIS), before being analysed for its ability to support fleet management. The trial outcomes demonstrated the capability for HUMS to deliver enhancements in fleet management through Condition Based Maintenance (CBM), automated data entry, enhanced operational statistics, and increased understanding of the platform’s mission profile.
