So, um, Nathan, um, can you kick us off with the history of the pr- of the system?

Yeah, sure, Grant.

Look, JORN has an exquisite history in Australian defense industry and defense in general.

You know, starting back in the 1950s, a gentleman named John Struth, who came out from the UK, started experimenting with high-frequency signals, uh, sending a signal between Adelaide and Melbourne and proving that they could refract a signal through the ionosphere, which is the phenomenon on which OTHR is based.

Uh, DST Group then, uh, took th- and built a Jindalee experimental system in Alice Springs, and from that research project, uh, they involved industry in the development of the Stage B system, uh, which now has become Radar 3 in the JORN network.

Uh, in the nineteen, late 1980s, the Australian government decided to invest in over-the-horizon radar as an economical way of providing maritime and air surveillance over Australia's northern reaches, and that, that initiated the JORN project, which delivered Radar 1 in Queensland and Radar 2 Western Australia, and a command and control center to control those systems here at RAAF Base Edinburgh in Adelaide.

Uh, from there, there's been enhancement programs, and we're now embarking on JORN Phase 6, which is a major midlife upgrade.

So BAE Systems Australia, what's BAE Systems doing, uh, with JORN? Um, what's the involvement and specifically both your departments? So maybe start with you, Nathan.
