"City of Hobart". A missed opportunity... do you know what makes this aircraft so special?

Well, it's Avon powered - whereas we eventually went with the Atar.
A missed opportunity - some sources say no - claiming "the performance advantages of the Avon were not sufficiently great to warrant the extra expense and the engineering problems that would go with it."

There was also the an "accounting error" on SNECMA's behalf that tipped the scales in favour of the Atar. Have you heard that story? ;)

And why it was called the Mirage IIIO....

The horror story of the Australian Mirage is something that I always wonder about.

Cost issues for instance over the use of the Avon. Australia already used the Avon in their version of the Sabre so any additional cost would almost certainly have been more than balanced out by cheaper training and support costs.

Performance. I haven't been able to find out in detail what the difference was but understand that the Avon powered aircraft was faster, had a much better climb, shorter field length, gun firing ceiling was over 10,000 ft higher, better combat manoeuvrability and approx 20% longer range. To counter this French offered the more powerful Atar 9K engine, but never delivered it.

Radar the Ferranti Airpass 2 multi mode radar was superior to the French Cyrano

Cannons The RAAF used the DEFTA not the Aden already in use in the Sabre. This resulted in ammunition problems as the RAAF spent A$519,000 on Ammunition as the French never gave them the licence to produce their own ammunition, whereas Australia had been producing Aden ammunition for years without any problems.

As I said a real horror story

Horror story sounds like an exaggeration - the Mirage III was one of the most successful combat aircraft of the Cold war era.
Some of the original Mirage III purchased by the Australians are still actively flying today in the Pakistani Air Force - they most be up to 50 years old?

Mind you - Mirage III had a very poor safety record in Australian service - lots of crashes and write-offs

There is no doubt that you are correct in what you say, but from a cost and performance perspective it was a horror story for the RAAF

Yup, it's a good one, managed to hoodwink the Americans. One of the CAC reps had been in France and had almost certainly made their mind up about the Mirage in favour of the F-104, requested that on the way home he should stop into Lockheed in Burbank, to which he was told by the French rep, a fella named Waquet (odd, since Laurie Wackett started the CAC, but anyway...) to tell Lockheed that he thought the Mirage was rubbish! This allayed Lockheed's suspicions, but the deal had already been done, the 'low' cost of the Atar being a factor, so it's said!

Interesting to note that Ronnie Harker, Rolls-Royce's Military Aviation Advisor was in communication with Australia about the Avon in the Mirage and he'd been in touch with Waquet (presumably Wackett as well!) about it and was keen, he of the suggestion that the North American Mustang I undergoing evaluation after arriving in Britain should be fitted with a Merlin engine, which started something, although he did comment that it looked a bit like a Messerschmitt Bf 109 because its designer had worked for Messerschmitt, even though he hadn't, but he can be let off that for getting Rolls-Royce to put a Merlin in the type, thus changing its fortunes...

Perhaps he should have been more persuasive with the Australians and the Avon...

As I said a real horror story
According to the Australian Serials & RAAF History sites:

A French Mirage IIIC, known as "City of Hobart", was fitted with an RB146 Avon 67 RA.29 (mk301) turbojet which produced 12,100 lbs thrust (15,715 lbs w/reheat), and flew on February 13 1961. This was known as a Mirage IIIO, but did not receive an RAAF serial number as, although the Avon delivered superior performance over the SNECMA Atar 9C [9,430 lbs thrust (13,670 lbs w/reheat)], it did not have a clear advantage over the under-development Atar-9K [11,023 lbs thrust (15,870 lbs w/reheat)], so the Atar was chosen on 17 May 1961. As it turned out, the -9K was experiencing delays by the time the RAAF Mirage III was ready to begin production, so the -9C was fitted in all RAAF Mirage IIIs produced. The higher cost of the Avon ($46.9 million vs $44.9 million for the initial 30-aircraft contract) was not very significant.

So basically, the French sold the Australians on the Atar-9K, but only delivered the weaker -9C.

Looking at the history of the Mirage IIIs in RAAF service, the ATAR 9C was the cause of several accidents and fatalities (but then, so were almost all engines of that generation).

I don't know where this image came from (found it somewhere on the internet), nor who made the statement quoted... but if true, then....

Secret Squirrel Nimrod R.1. The RAF for many years officially denied the existence of the unit that operated these aircraft. Also took part in the Falklands War as a standard Nimrod MR.2 maritime recon aircraft before conversion to an electronic warfare platform.

Inside the Cold War building, for which the museum was granted special funding for developing a Cold War-themed museum, but in reality, the museum used the money purely so it could get its bigger aircraft undercover.

The first Eastern Bloc aircraft to go on public display in the UK, a Polish built SB Lim-2 that was acquired in 1986 and made its public debut at the RAF Museum at Hendon that year.

Vulcan XM598 was a backup aircraft to XM607 during the Operation Black Buck raids, attacks on Argentine held Port Stanley Airport during the Falklands War.

The clever part of the British deployed Polaris A3 missiles, its Chevaline warhead carrier, a self-contained spacecraft, which manoeuvred itself into position before deploying its warheads using retro rocket motors around its base, not visible in this image, it could also launch decoy flares to deter anti-ballistic missile defences. Quite possibly one of the most ambitious and expensive aerospace projects the British developed during the Cold War that no one's ever heard of...
