In 1958, the RAAF was seeking a replacement for the sub-sonic Canberra medium bomber.  The CSIRO (Commonwealth Science and Industrial Organisation) was approached by GAF (Government Aircraft Factories) to help in designing an indigenous aircraft.  CSIRO had long had an interest in computerisation and automatic guidance systems.  They appointed Dr. Mark Golf to head the study team and his team in six months produced a proposal for a self-guided air-breathing missile.  Powered by a Rolls-Royce Avon jet engine, fed by a dorsal intake, the Inapertwa (Aboriginal for "simple creatures"), the missile would have sufficient range to reach northern Manchuria from bases within Australia's "top end".  Equipped with a initially a 5,000lb conventional warhead, later updated to a multi-kiloton nuclear device, it was to be capable of destroying it's intended targets.  Road mobile, the missile was to be kept in large, concrete bunkers and in times of stress, dispersed to the surrounding countryside and readied for launch using zero-length rocket boosters.

If you want to be more classical, you could paint a black canopy in this aircraft, but it seems this is not your goal. :)

Looking forward to this.  Are you going to do it in a truck mounted form?

You could make them dispersible by rail, but that might be a problem crossing various state borders in oz.

Unfortunately, not much in the way of railways in the Top End in the 1960s.  The Central Australian (Ghan) line goes from Port Augusta and stops in Alice Springs.  The Mt.Isa line goes from the east coast and then stops at Mt.Isa.  There is some railways along the east coast but apart from that, not much at all up that way.   For rail mobile launchers to work, you did a widely diffused rail network.  Much more roads even if most are only dirt tracks up that way.  Much easier to make them road mobile.  Centrally housed for security and maintenance and disperse them in times of stress for a much harder to eliminate targets.

Well I actually drove past the entire length of the North Australia Railway today, including many of the old disused rail bridges that can still be seen across many rivers.  There is a museum at Adelaide river that I need to take my kids to see sometime to find out more but hers some info.

https://en.wikipedia.org/wiki/North_Australia_Railway

History[edit]

In the nineteenth century the Northern Territory was administered by the Government of South Australia. The John Cox Bray Government introduced the Palmerston and Pine Creek Railway Bill in 1883. The £959,300 contract was awarded to C&E Millar of Melbourne on the proviso that they could use coolie labour. The line reached Pine Creek in 1888 and officially opened on 30 September 1889.[1] Singhalese and Indian gangs did the grubbing and earthwork and 3,000 Chinese labourers laid over one kilometre of track per day. A total of 310 bridges and flood openings were built.

Commonwealth takeover[edit]

The Commonwealth Government took control in 1911, having promised to complete the railway from Adelaide to Darwin but without setting a time frame for so doing.

The line was extended to near Katherine in 1917. A further extension saw the line reach Birdum in 1929.

In 1930 a mixed train, called Leaping Lena[2] ran to an established timetable.
Depart Darwin at 08:00. on Wednesdays
Arrive at Pine Creek at 16:46
Depart Pine Creek 08:00 on Thursdays
Arrive at Katherine 11:00 on Fridays
Depart Katherine 12:00 Fridays
Arrive at Birdum 17:51 Fridays

During World War II Larrimah, nine kilometres north of Birdum, became the effective railhead as it was on the Stuart Highway, unlike Birdum. The 100 metre bridge across Birdum Creek is still present. There were locomotive turning triangles at both locations. The busiest time for the railway was during World War II. As many as 247 trains ran per week in 1944.

Proposed extensions[edit]

A railway line from Alice Springs to Darwin had been discussed and promised by politicians for many years.

A railway between Alice Springs and Birdum was proposed as early as 1918, before the two lines had reached those locations.[3][4]

A private company proposed a railway from Birdum to Bourke, New South Wales in 1932.[5][6]

Following the outbreak of the Pacific War, the Australian Army surveyed a rail route from Alice Springs to Birdum in 1942[7][8] and from Mount Isa, Queensland to Birdum via Tennant Creek in 1943.[9]

A railway from Dajarra, Queensland to Birdum was considered in 1952-53[10] but the Cabinet decided not to proceed.[11]

Construction of a standard gauge railway to Darwin was first seriously proposed in 1965 when construction of a new standard gauge line to Alice Springs was discussed.[12]

Closure and completion[edit]

Main article: Adelaide–Darwin railway

The Federal Government promulgated an order to close the narrow gauge North Australia Railway line on 20 May 1976, with services ceasing on 30 June of that year, as result of the loss of iron ore traffic originating from the Frances Creek operation. Maintenance gangs were withdrawn in December 1977. Heavy floods in 1978 destroyed significant parts of the railway, effectively eliminating any hope of the railway re-opening. In 1985, some rails and sleepers were lifted and sent to AN Tasrail.[13]

Nearly 20 years later, the AustralAsia Rail Corporation a consortium was formed to build the standard gauge link between Alice Springs and Darwin.

Construction on the new standard gauge line from Alice Springs commenced in July 2001 and was completed on 17 September 2003. The first freight train reached Darwin on 17 January 2004 and the first Ghan passenger service ran from Adelaide to Darwin in early February 2004. The line runs near the route of the North Australia Railway in places but uses very little of the old infrastructure.

The Pine Creek railway station is on the National List of Significant Places at the National Trust of Australia.


So there was a railway in the Northern Territory, a narrow gauge one, until 1976, there are also the North Cost Line, the Great Northern Railway and that Tableland Line all in North Queensland.

Beautiful!!  You captured the proper clocking of the boosters, too (thrust vector has to pass through the combined vehicle cg or you have stability problems on launch).  Somewhere, I have a copy of the procedure for setting clocking and verifying nozzle cant when installing the boosters (was reference for dealing with booster installation on Army-TSSAM).

Tempted to do a manned version of this - maybe something akin to the GAF Pika that preceded the GAF Jindivik (see below):
