Rampart loaded with 3x4-cell pods for 12x Mistral-3 + 1x-12-cell pod for 70mm APKWS-II weighs at least 2,916kg, probably more. The launcher itself reportedly weighs exactly 2.5t empty. This would still appear to rule it out however as the "maximum above-deck weight for each fully operational Effector Station (ES) shall not exceed 2,500.kg". We know that each of the Phalanx positions can handle a weight of well over 6t, so the 2.5t limit probably indicates this system will be positioned elsewhere, maybe further forward where the Royal Navy depicts installing Dragonfire.

I’m assuming this isn’t news, but the RAN official website leaves the door pretty open to Japan delivering more than the first 3 Mogamis. The wording is very intriguing - either conceding Henderson won’t be ready or the cadence of Japan builds will deliver the capability faster.

Three years to build our first Evolved Mogami. How long will we take per hull? Based on the Hunter, admittedly a more complex build, I would suggest considerably longer.

Im not sure on timeline of production of Mogami,s in Japan versus Australia and certainly the cost of the build is likely to be different ,but would it address some issues if Mogami,s were initially built in Japan and sent to Australia to be finished off per customised needs

It appears the timeline in Japan is about three years. I am hoping we can get as close to that as possible. Hunter is at a snail's pace. The RN have their first two Type 26s I believe in the water with Belfast fairly advanced. I know Hunter is a more advanced evolution but the Brits are likely to have most of their eight hulls in the water before we get our first!

It’s looks to be around 5-6 years for the first to be built and then every 2 years out to 2050. Might be quicker for the later ships, say 2046 if sped up.
If the shipyard is not ready by 2030/31, more than likely a 4th will be built in Japan.

Five to six years for local Mogamis? Why will it take us nearly twice as long as the Japanese? They have already started our first.

I think the government's proposed cadence is deliberately slow to balance budgets, and likely behind what a yard could actually do.

Note this principle is in all the military facilities that are being built, not just Henderson. 155mm shell manufacture for an order of 10,000 per annum, but capability of 100,000 etc etc.

I am hoping that once Hanwa has purchased the American assets, MHI will buy into the Australian business, wholly or partially. Then we can look to obtain some important synergies.

Sammy, why are we so bloody slow when we could be at war in a couple of years? It's all political. Russia has their economy on a wartime footing. We need to pull our collective fingers out. I'm more worried about Putin than Xi Jinping. China has a lot riding on it's trade with the West and will hesitate. Putin doesn't think twice about sacrificing his own people.

The first is five to six years - then every couple of years. They have to build a shipyard, import the design (ie translate the build documentation into English) and train a workforce. That all takes time - and is a problem if you insist on not having a continuous shipbuilding program in an existing yard. That is, if your politicians decide that pork barrelling to their state is more important than speed (or efficiency) of construction. Six years to do that is actually quite quick.

Ah, pork barrelling. It's like a cancer in our society with all politicians. Just once I'd like someone who genuinely cared about US!

The yard infrastructure is still being built con current with the construction of the first ship and the design is still being updated with information coming in from the UK build.

These ships are massive, just look at the images from the Keel Laying.

The Mogamis are half the size of the Hunters, but still larger than the old FFGs.

Effectively the Hunters are Light Cruisers at 8.000 tonnes plus, particularly if they do get two Mk.49 RAM launchers. They will have more firepower than the base Type 26.

IIRC Australia's getting the enlarged Mogami, same as now in production for Japan. The last two of the original Mogamis are in the water & fitting out. The RAM Mogamis will be 6200 tons full load, or over two thirds of the tonnage of the Hunters according to the numbers I've found online. A bit different from half.

And they will have three to four times the firepower of the ANZACS.

Deeper magazines for sure.

Which gives longer endurance on station if located somewhere like the middle east.

Less beneficial in the Indian Ocean or South Pacific where they are unlikely be facing large scale drone attacks or saturation missile attacks.
