The only possible reason I can think of for this totally perplexing announcement is that the ships are being transferred to Border Force with their stricter rules on heavier weapons...
Could be the case

My bet is they are destined for the Virginia Class.

Time will tell. :rolleyes:

There has been some discussion in the media regarding the latest CRS report to Congress on the Virginia Class (see link below for those who have not seen it). Some commentators are hyping this while others are playing it down as nothing. I think this last report though, is a bit more significant.

Even though the CRS reports to Congress don't provide recommendations, they do build cases for and against policy issues under consideration by Congress. The significance of the latest report IMO is the considerable hardening of the case against Virginia transfers to Australia when compared to previous versions of the same report.

The AUKUS subject does ignite emotions.
The CRS report raises fair questions for the USA if we don’t go “all the way “ as it does for Australia ,should we choose not to go “all the way” in the Virginia Class construct.

How and why these questions were not addressed before the deal was settled seems perplexing, but it does sort of make sense re the speed to which this deal was put together in the first place.

So a sovereign capability for the ADF or not.
Did we realistically think the US were going to through us the keys to a Virginia SSN and they were not going to have considerable expectations of its use and deployment in both times of peace and conflict.


AUKUS an interesting gamble!

This just gets worse and worse. Make a deal and stick to it!

Stay with me here guys, before the hand-wringing gets too out of control.

Congressional. Research. Service.

Their literal job is conduct research and provide options to Congress. Congress is not obliged to accept such options. They are discussion points only.

Remember when Trump said he actually wants AUKUS accelerated if possible? Remember when Joe Biden actually signed the thing and agreed to it, to begin with?

Remember when both sides of Congress overwhelmingly voted in favour of AUKUS and passed legislation that literally allows it to happen?

Real action. By those in charge.

Not an options paper by a library, guys…

Precisely. Ronald O’Rourke has been the head of the Naval research section for years; there are dozens of reports under his name available on all sorts of subjects. And each one of those provides analysis on both sides of the matter being discussed. Their purpose is to inform members of Congress on the subject, and arm them with multiple arguments around the subject. You can, for example, find arguments for and against almost every acquisition program, major or (relatively) being run or contemplated by navy. O’Rourke is widely respected for the impartiality he brings to his work; but he does not make policy.

I understand that the post LOTE Collins class will not be fitted with Tomahawk missiles and will keep using Harpoon missiles as there is currently no sub launched version of the NSM - are there any plans by the ADF to modify the Harpoon’s seeker to the new Block II+ version? This would give them limited capability against shore targets in addition to ships.

My understanding is that the answer to that question is no.

The RAN employs the UGM-84D Block 1C Harpoon missile from it’s Collins Class submarines. It may be the case that RAN acquired UGM-84 (submarine launch capable) variants have been life extended through sustainment activities and upgraded to the UGM-84G standard.

The AGM-84 and RGM-84 missiles acquired by ADF (air-launched and sea-launched) have been A/RGM-84D models and upgraded into A/RGM-84J standard missiles (which is how Harpoon Block II missiles are designated) but as they have been developed from the -D model, my understanding is they are too long to be fired from submarines, which is why the RAN UGM-84 models have seemingly remained ‘stuck’ at the Block 1C or possibly G standard.

It will be interesting to see where RAN goes from here with submarine launched missiles. Apart from Tomahawk and Harpoon, there aren’t very many Western options for submarine launched anti-ship or land attack missiles. The French Naval SCALP is the only other one AFAIK and clearly we won’t be going with the French option in submarine matters…

HMAS Stalwart is in Hobart for the Royal Hobart Regatta. Unfortunately the regatta is only a shadow of its former self but the navy and the RAAF still do their best to support it, with the Roulettes performing over 3 days including during atrocious weather on Sunday.

No “up-gunning” on the Arafuras.

In fact, no gun at all… :rolleyes:

What an absolute joke.

Remember when I said people might be jumping to conclusions when the RAN revised it‘s “threat assessment” on the OPV’s? Everyone imagined this would be in line, with the oft-repeated decline in our strategic circumstances.

But no. RAN has reached the conclusion, that somehow these 1600t grey hulled ships, are somehow now at less threat, than the 25mm gun armed Armidales were… :D

From OPV2 onwards, a solitary rifleman in any battalion you like, is as well, or better armed than a 1600t RAN warship…

View attachment 54271

My personal reading of this is that viewing the OPVs as "1600t grey hulled" ships has been a misnomer ever since their role was rescoped. This shouldn't be all that surprising with them now arriving in a very different RAN than the one they were conceptualised for. The force command they were meant for no longer even exists in the same form, with MHP force now being split between PB Group and MDGFOR.
They are best thought of as grey hull ships to implement much of the testing work being done on the large ADVs in a more operationalised form, mostly for the needs of MDGFOR. If the Leeuwin's and now Cape class don't need guns bigger than .50, then it begs the question why draw more scarce ETs up to Darwin and Cairns to operate/maintain weapons on ships which will be doing much the same work?
I think with emerging threats in the littoral (where these ships will be) particularly unmanned systems, this logic could well end up reversed in due course although perhaps not before the ET intakes start getting larger.
Just my two cents on the matter from current observations of relevant factors.

Maybe they want to go back to Attack class PBs (Sarc)

Depends on the model. If hydraulically activated, which most Navy were, you would; from memory (of long ago) the motor and pump were on the mounting.

Interesting the weapon / sensor/ aviation capabilities across the world re nations constabulary forces, be they a coast guard or naval vessel.

Most have something more than a heavy machine gun.

There would be a reason for that necessity and trend.

Well the RAN certainly seems to be trying to set a new trend! The Arafuras must just about be the lightest armed OPVs in the world. A deliberate decision to remove aviation facilities has now been followed by deciding to not even reuse the existing 25mm bushmasters. Installing the mount on OPV2 without adding the gun beggars belief. The navy must be very short of cash and personnel! Regardless of the need for anything more than 2 HMG for whatever the planned role may be, it seems to me that a main gun would be useful for training. It would also add to the prestige value of the OPVs when showing the flag.

If they're still intended for primarily constabulary duties I can't see them lasting long in the fleet. Seeing as they're not under Patrol Boat Group or Surface Force but rather Mine Warfare, Clearance Diving and Geospatial Force I am quite confident that's no longer the plan for them. The Capes have pretty well replaced the ACPBs already while the Huons and Leeuwins were looking like the last of their kind. I think the greater need is being served here albeit a 25 or 30mm would've been nice.

If it was an all in deal…If for whatever reasons Virginias are not forthcoming Australia would be within rights to say no to WA basing for the USN.

one of the Admirals there stated they found the Arafura design was not compliant with Australian maritime safety standards in relation to fire
Senate estimates - Defence


7hr 45m - OPV gun discussion.

No gun for ships 3-6 but potential for new gun.
One of the Admirals there stated they found the Arafura design was not compliant with Australian maritime safety standards in relation to fire structural fire protection with work to do to resolve safety issues in the class. WTF! They Didn’t work that out when choosing the ship? How is that possible?
