Australia never had LORAN. At one stage I think a Decca system was
trialed, but never installed.
We had a system of secondary radar called DME from the late 50s -
early 60s. A randomised pulse pair was sent out from the plane and
was received
by a beacon at the airport. The beacon digested it for 14 odd
microseconds and sent out a reply pulse. The two way delay was displayed
in nautical miles on a cockpit indicator. The range was 200+ miles at
VHF and the pulse pairing could interrogate other beacons by changing
pulse spacing.
With three beacons and a compass how could you get lost?
I do not know how shipping located themselves.
cheers, Neville Michie

originally produced in the 1940s. I used a periscopic sextant in
the KC-135, an improvement over the hand-held, or dome-mounted
bubble sextant, but I never used any sextant in the Fairchild
Republic A-10A "Warthog" I subsequently flew. Interesting
coincidence with nomenclature. Using a sextant in my single-seat
Warthog would have been a trick! I confess to having drooled over
Loran C while serving as a nav in SAC. When I eventually installed
Loran C in my personal Mooney aircraft, I was quite pleased with
its performance, but there's no question that GPS has eclipsed
Loran in many ways for global navigation. Strangely enough, the
only Loran receiver I saw operationally in the USAF was Loran A, in
the KC-135Q, to improve navigation for rendezvous with the SR-71.
It was quite a dinosaur, even in the '70s.

Heard you guys flew the wings off those planes. Boeing is replacing
all 242 wing sets for another 20 years of service.
Thanks for your service, Peter.
