The Life of Type Extension (LOTE) of the Collins Class submarine fleet will provide the nation with world-class submarine capability into the 2040s and beyond.
The Collins Class are internationally regarded among the best conventional submarines in the world. ASC will continue to deliver its current level of world-class boat availability to the Royal Australian Navy throughout the implementation of the LOTE program.
During the program, ASC will replace the propulsion systems, diesel motors, generators, power conversion and distribution systems as well as carrying out a range of hull assessments and upgrades. ASC will integrate this new equipment into the existing command and control system.
The LOTE will be implemented on all six submarines in the Collins Class fleet.
Currently in the planning and design stage, ASC is working closely with the Royal Australian Navy, the Capability Acquisition and Sustainment Group (CASG), Australian suppliers and international partners to deliver the Royal Australian Navy’s specific requirements.
ASC is on–schedule for the First of Class implementation of HMAS Farncomb in 2026.
