Defence has finally (partially) updated the Navy's page on the Hunter Class.

The crew size has grown substantially to 183 excluding embarked flight crew.

With accommodation for only 208, after flight crew for a single MH-60R is embarked there will be hardly any accommodations remaining.

That means whilst there's space in the Mission Bay for a second MH-60R and various uncrewed systems, there's no space to actually accommodate the crews required to operate said systems/aircraft.

This then begs the question, what's the point of the mission bay space if there's not enough accommodations to even utilise it?

An interesting update, great to know that (according to the page) they began (?) to enter service "in the early 2023". So I guess with that edit and otherwise poor grammar it's not a terribly reliable source of info. The linked PDF still describes entry of service in the late 2020's.

This mission bay can also be used for unmanned systems.
I expect that for the bulk of the time these will be its primary use

Uncrewed systems still require dedicated specialists to maintain, launch, recover, monitor and/or remotely operate pending level of autonomy.

For example, If you embark a MCM or ASW USV, you'll also be embarking the USV's specialist personnel.

Do these have to be in addition to the crew?
Cannot crew members also be specialist personnel?

The Canadian combatant is 210.
UK specs 118 but with room for 208. But sometimes quotes at 153 with the ability to embark 57 troops.

Colour me suprised. The Hunter class seem to have the exact same crewing requirement as a Hobart.. 186 + 16 aircrew. Oh, looks like the hunter class requires 3 less people. So much for automation resulting in not requiring crews. Makes for astonishing headline, ship requires crew to operate.

What was an Anzac class? 165 + 16 aircrew?

I wouldn't get overtly excited about crewing numbers until its in service, and FOC. Crewing numbers can change depending on deployment type, systems, etc.

The 118 figure comes from when the 'Global Combat Ship' was a concept in its infancy.

The RN quotes the Type 26 will have a crew of 161. This figure likely excludes embarked flight.

The concerning aspect for Hunter is that 183 crew plus 16 flight crew brings the ship up to 199.
As per the RAN's site, Hunter still has 208 accommodations (Hobart has 234), meaning after embarked flight there's only space for an additional 9 personnel.

That's not enough to embark crews for a second MH-60R, UAV(s) and/or USV(s).

I'd imagine that would be a bit like getting a sonar operator to manage fire control. They're different specialist skill sets.

Still no update on the final number of VLS? Why is that such a secret?

Hello community, I just joined as I'm hoping someone here can help me with some info.
When I was a kid I was living in Singapore as my dad was RNZAF based at Sembawang. I was lucky enough get a walk-through of a RAN Submarine at base there and only have one photo of the experience. Photo is dated 28th Nov 1979. Question for the group, does anyone know which one this was?
I'm hoping the shield on the front gives it away? Looking it up, this was one of 6 Oberon class subs in RAN service at the time: Onslow, Orion, Otama, Otway, Ovens, or Oxley, so assuming it was one of them?

Someone must be feeding him.

I am still skeptical of a AU-UK submarine. In Australia's context, we don't need a sovereign unique design separate from the Americans. If we could build Virginia's that would be seen as a success.
I had at first preferred the RAN get Astute SSNs but that seems off the table. The further away design finalisation of the SSN AUKUS gets, the more my position shifts to yours - getting current design Block IV Virginias. Block IV would suit the RAN well and have very little risk, being now in production and first hulls going into service. I am constantly dismayed by how much RAN senior officials seem to underestimate the significance of design risk in incomplete designs.

The problem I suspect is legal and commercial, not technical. There are many classified technologies in the Virginia design, not only the reactor. Each one requires a separate Congressional approval to be voted through Congress for it to go to a foreign power, including Australia. Also very little of the US submarine supply chain firms are based in Australia. A lot more of the UK SSN supply chain firms are already based here.

I thought the Hunters were meant to have more space for future growth and fit-out than the Hobarts? If the Hobarts are smaller (7000 t full load vs 8800 t full load) than Hunters, yet have more VLS, where does the extra space go in the Hunter design? Is there enough margin for future changes in Hunter, given that reportedly the spare hull margin in Hunter was also limited?

Conversely, is the quoted tonnage correct? Last year the Australian quoted modified Hunter tonnage as approaching 10,000 tonnes. 8800 tonnes was the quoted full load displacement of the UK Type 26 GCS.

The large mission bay and a flight deck large enough to land a Chinook on, neither of which the Hobarts have.

That's not one of the O-boat crests, and it's a bit hard to make out in such low resolution. Too bad whoever took the photo didn't lean to the right a bit over the casing to make out the boat's name plaque on the side of the fin. ;)

As DDG38 said that's not an Australian Oberon class heraldry. I just tried to search to see if there was any RN Oberon shield that make look like that and I can't find really anything like that one.

I would guess that it is probably Ovens. Oxley I think was in refit still during 1979.

The RAN site actually has a lot of history of the submarines, and during the 70's many were going through refits. If you go through carefully maybe they might have the exercise or deployment listed for one of the subs.

Ovens and Oxley I think were most commonly deployed to SEA/Singapore. My old man was on Onslow and complained he never went to Singapore as a submariner, he went to the UK, Hawaii, and for some reason to Mexico. It may not be a ships shield but a ship award.

People seem to think the Hobarts and the Hunters will have wildly different dimensions. Hobart is 147.2 m in length and Hunter is 149.9.. Even parked next to each other you would be hard pressed to see the 2.7m difference. Hobart is slightly narrower and has a bit different hull form. But its not wildly different, about a 1-2 meters (18.6 vs 20.8) .

If you make the passages 250mm wider across the ship it can easily eat into that extra margin. Throw in things like a ladies toilet, modern firefighting and damage control, more room for power, networking, better aircon/mech services.
Which is why I think people shouldn't get overly excited about displacement and fixate on sizes. Select the capabilities you want, then build the ship around that. Artificial size limits are just odd. 5,000-7,000t might be a range on a military ship depending on load, commercial ships can vary 100,000t depending on load, same ship.

Australia should be building massive ships. Its not like we have small harbors, or we are running out of iron or that the iron is expensive for Australia.

Hobarts are more focused ships. They have two Gas turbines. They have more VLS, command and control spaces, etc. Putting a big flex space in the middle of the ship chews up space/weight etc. IMO that is precious space, not sure we need our surface combatants to move shipping containers around.

I find it interesting that the Canadians spec 210 sailors, despite their ship going with less weapons and more automated weapons (like CAMM and the OTO 5" which is basically completely automated for the first 52 rounds, but takes up more hull space)

That crest is not RAN, our crests have a boomerang and hammer under the shield, it’s probably RN or, unlikely, RCN
