I'd raise an eyebrow at the JORN capability 'dezinformaciya' repeated without question in post #4062 and #4125, thus:
"I can well understand the Australians being very cagy about releasing any data analysis which might give clues and cues regarding the extent and limits of their OTHR system, but I am wholly confident it now exceeds by some margin what is widely reported in the public domain.
Viz:
"The Jindalee Operational Radar Network (JORN) is an over-the-horizon radar network that can monitor air and sea movements across 37,000 km2. It has an official range of 3,000 km.
....the JORN delivered in 2003 was designed to a specification developed in the early 1990s. During this period the Alice Springs radar had evolved significantly under the guidance of the Defence Science and Technology Organisation (DSTO). In February 2004 a fifth phase of the JORN project was approved. This phase aimed to upgrade the Laverton and Longreach radars to reflect over a decade of OTHR research and development. Phase five was scheduled to run until approximately the year 2011.
......other sources put the range at 4000 km from the Australian coastline,, as far away as Singapore The JORN is so sensitive it is able to track planes as small as a Cessna 172 taking off and landing in East Timor 2600 km away. Current research is anticipated to increase its sensitivity by a factor of ten beyond this level.
....JORN is designed to detect air targets equivalent in size to a military BAE Hawk-127 jet-trainer aircraft or larger…….enhancements planned beyond Phase 5 are unlikely to markedly improve the system’s ability to detect a vessel smaller than an ACPB patrol boat" ( my emphasis )
A meeting in recent years of the Qinetiq/RAF Boscombe Down branch of the RIN had a presentation on developmenst in OTHR in general and Jindalee in particular. Most of the attendees were Very Senior Development Electronics Engineers and some of the questions and answers were particularly probing and frank. It was clear that operating range 'on a good day' was very considerably more than 3000km and there was brief comment about tracking North Korean missile launches.....
It makes little sense to have a world-class threat tracking system, costing A$billions, and not have it running almost all the time. Does anyone really believe that the published FAQs of this VIP defense capability reflect its full operational range? Bolleaux!
I'm aware of the 'Inverse Square law'. Nevertheless, I suspect the 'Strines will have something to add to the discussion, albeit behind closed doors, and most likely 'shared' with their US allies.
