The JORN defence system is a network of three remote over-the-horizon radars in Queensland, Western Australia and the Northern Territory.
It provides wide-area surveillance to support the Australian Defence Force’s air and maritime operations, border surveillance, disaster relief, and search and rescue operations.
As part of the decision, the company will submit its tender as a prime contractor for Project Air 2025 Phase 6.
Bae Systems Glynn Phillips said: "BAE Systems is totally committed to continuing its long term association with JORN.
"Our team is proud to have supported the Defence Science and Technology (DST) Group in creating the original long range high-frequency radar system used by JORN and we have continued to invest in developing, supporting and enhancing this wholly Australian owned technology over the past 35 years.
"We are currently working closely with the government and DST Group to upgrade aspects of this critical technology in readiness for the major Phase 6 undertaking."
Designed to extend the operational life of JORN beyond 2042, the Phase 6 upgrade is expected to take place in 2018.
The company is currently working with the US Government to supply a multi-channel, high-frequency receiving system based on the JORN Phase 6 technology.
Work is expected to be completed by the end of next year.
