Australian DoD considered walking away from $50 billion French submarine deal

Australia's government owned ABC News reports, January 14, 2019:

"Defence secretly considered walking away from the $50 billion French submarine deal during protracted and at times bitter contract negotiations, and started drawing up contingency plans for the new fleet.

The revelations are contained in a new report [here] by the [Australian] auditor-general that also confirms the program is running nine months late and that Defence is unable to show whether the $396 million spent so far has been "fully effective"...

Argentina Might Buy 2 Ula Class Submarines from Norway: US, UK Opposition?

On January 9, 2020 at 3:14 AM Nicky asked  "Hey Pete. What's your take on this. Looks like Argentina is interested in buying the Ula class SSK from Norway. [See] "Argentina: Estudian la compra de dos submarinos noruegos clase 'Ula'"

Pete's Response

Thanks Nicky for https://www.elsnorkel.com/2020/01/argentina-estudian-la-compra-de-dos-submarinos-noruegos-clase-ula.html about Argentina, Germany and Norway studying the possible Argentine purchase of two 1,000 ton Norwegian Ula class short range submarines.

One problem is the Ulas have been active for 30 years, making them quite old - see https://en.wikipedia.org/wiki/Ula-class_submarine#Vessel_list . After the sinking of the very old ARA San Juan in 2017 many in the Argentine politico-military complex and the public may not be enthusiastic about the Argentine Navy buying subs that are already old - therefore more potentially accident prone.

Another problem is Norway's alliance relations with fellow NATO members, Britain and the US. Britain is in a tense dispute with Argentina over the Falklands/Malvinas islands https://en.wikipedia.org/wiki/Falkland_Islands_sovereignty_dispute .

The British (and US) may pressure Norway not to export Ula submarines to Argentina. The Falklands/Malvinas islands dispute, of course, resulted in an actual war between Argentina and Britain in 1982 https://en.wikipedia.org/wiki/Falklands_War . This war put US - Latin America relations under pressure because the US was forced to militarily choose to back Britain in intelligence and supply of some high tech equipment terms (eg. more modern 
Sidewinder missiles used by Britain Harrier carrier jets (see paragraphs 10 to 12))..

The British saw the Argentine submarine force as very threatening in 1982 and at other times. While the Argentinians found the British submarine force to be deadly https://en.wikipedia.org/wiki/Falklands_War#Sinking_of_ARA_General_Belgrano .

On the other hand the British may feel better about Argentina getting very old, more easily detectable, Ula submarines, rather than new, more potent, submarines. Also Norway and other Ula component suppliers and upgraders might be expected to leak vital Ula characteristics and vulnerabilities to Britain...

Poem: Australian Bush Fires At Christmas


This year Australia has been wracked by bush fires for weeks. This is before Australia’s hot weather Southern Hemisphere Christmas. This makes The Fire at Ross's Farm, written around 1895 by Australian poet Henry Lawson, especially poignant.

In this excerpt of the poem a rich farmer (“squatter”) seems to want to let his neighbour (Ross’s) small farm burn. But the squatter's daughter (and his conscience) persuades him, and his men, to save Ross’s farm. The poem evokes the insidious nature of fires and how people can work together to stop them:

"...One Christmas time, when months of drought
Had parched the western creeks,
The bush-fires started in the north
And travelled south for weeks.
At night along the river-side
The scene was grand and strange
The hill-fires looked like lighted streets
Of cities in the range.

The cattle-tracks between the trees
Were like long dusky aisles,
And on a sudden breeze the fire
Would sweep along for miles;
Like sounds of distant musketry
It crackled through the brakes,
And o'er the flat of silver grass
It hissed like angry snakes.

It leapt across the flowing streams
And raced o'er pastures broad;
It climbed the trees and lit the boughs
And through the scrubs it roared.
And with the stock the kangaroos
Went flying for their lives.

The sun had set on Christmas Eve,
When, through the scrub-lands wide,
Young Robert Black came riding home
As only natives ride.
He galloped to the homestead door
And gave the first alarm:
‘The fire is past the granite spur,
‘And close to Ross's farm.’

‘Now, father, send the men at once,
‘They won't be wanted here;
‘Poor Ross's wheat is all he has
‘To pull him through the year.’
‘Then let it burn,’ the squatter said;
‘I'd like to see it done —
‘I'd bless the fire if it would clear
‘Selectors from the run.

And there, for three long weary hours,
Half-blind with smoke and heat,
Old Ross and Robert fought the flames
That neared the ripened wheat.
The farmer's hand was nerved by fears
Of danger and of loss;
And Robert fought the stubborn foe
For the love of Jenny Ross

But serpent-like the curves and lines
Slipped past them, and between,
Until they reached the boundary where
The old coach-road had been.
‘The track is now our only hope,
‘There we must stand,’ cried Ross,
‘For nought on earth can stop the fire
If once it gets across.’

Then came a cruel gust of wind,
And, with a fiendish rush,
The flames lit the fence of brush.
‘The crop must burn!’ the farmer cried,
‘We cannot save it now,’
And down upon the blackened ground
He dashed the ragged bough

But wildly, in a rush of hope,
His heart began to beat,
For o'er the crackling fire he heard
The sound of horses' feet.
‘Here's help at last,’ young Robert cried,
And even as he spoke
The squatter with a dozen men
Came racing through the smoke.

Down on the ground the stockmen jumped
And bared each brawny arm,
They tore green branches from the trees
And fought for Ross's farm;
And when before the gallant band
The beaten flames gave way,
Two grimy hands in friendship joined —
And it was Christmas Day."

Despite the fires, have a Merry Christmas, especially regular contributors and commenters from around the world.

Part Australian Aquabotix SwarmDiver a Micro Diving USV

The Aquabotix SwarmDiverTM is a Micro Diving USV (Unmanned Surface Vehicle) utilizes swarming technology to act as a single entity. SwarmDiverTM is capable of synchronous vertical diving, is easy to deploy, and has a max dive depth of 50 meters. For Defense and Ocean Research.


Published on Youtube April 11, 2018. Particularly gets interesting 52 seconds in -  describes some military applications and ease of use.

About Aquabotix - It is “Based in Sydney, Australia & Rhode Island/Radford Army Ammunition Plant, USA... Aquabotix focuses on the design and development of micro-sized, swarming autonomous products for a range of defense applications where urgent requirements exist. We provide cutting edge, flexible use man-machine teaming solutions to counter persistent, growing, and developing security threats.”

For example:

https://www.aquabotix.com/swarmdiver-nightline.html  “The SwarmDiver NIGHTLINE system was created with special forces operations in mind. The camouflaged, low-visibility exterior and reduced-noise motors allows this vehicle to operate with stealth. Ultraviolet coating supports night-time/low-light environment recovery or lane marking”

and

https://www.aquabotix.com/swarmdiver-stealth.html  “SwarmDiver [Stealth] is designed to covertly collect information in littoral environments where waters may be monitored visually or with a range of sensor types. The low profile of SwarmDiver in the water makes visual detection of the vehicles challenging. The low infrared signature also helps ensure detection avoidance for the system.”
