The new 100 design looks like a mini 054B.Specifications very scarce at this stage from what I can gather, but a new, much larger 'Vigilance-100' design by VARD has emerged for the Canadian 'Continental Defence Corvette' program to replace their 'Kingston class 'coastal defence vessels'. I understand this is a R.A.N forum but we speculate about foreign OPV designs all the time, in particular as of late, the forthcoming large, low-crew JMSDF design.
An older article somewhat detailing the 'Vigilance-75' flight I & II designs to illustrate how the design has evolved over time, presumably from continuing input from the RCN. Even this was a promising design for a ship presumably a little smaller than the Arafura class.

Vard: Vigilance and expectations
The Vigilance concept continues a long line of waiting for something that won't existnoahscornerofrandomstuff.substack.com
Crew requirement obviously the key, that's the greatest aspect of the Japanese design, 30 crew for its size is absurd compared to what else is on offer.The new 100 design looks like a mini 054B.
Not much info atm.
The Vard 75 flight I crew size is also 20-30. Flight II probably more.Crew requirement obviously the key, that's the greatest aspect of the Japanese design, 30 crew for its size is absurd compared to what else is on offer.
What's the chances of cascading the CEAFAR, Mk41s, etc onto the big ships? Seems a logical step with the equipment becoming available. Choules recently had a radar installed so surely there's space for a launcher?Exactly.
With the big(ger) ships that don't have provision for VLS or too small a VLS ADL.has potential, especially if there is an expandable base combat system that is comparable with some modern, but now surpluses radars you happen to have.
We should be looking at what it would take to install the masts from the ANZACs and ADL on the LHDs, maybe the AORs and Arafuras.
But the SWAP (space, weight and power) is just one of the considerations. There is also the weapon magazine, fire suppression, CMS, manning (operators and maintainers) and others to be considered.What's the chances of cascading the CEAFAR, Mk41s, etc onto the big ships?

The big ships and the OPVs have the same core CMS as the ANZACs and my original post was about the ADL, basically a slant deck housing for Mk-41 missile canisters.But the SWAP (space, weight and power) is just one of the considerations.

Perhaps, but they don’t exist today in an operational state, have they been fitted to a real warship and live fired as IRIS-T now has? To my knowledge no-one has ordered them and so is the German appetite to be an orphan operator of such any greater than ours? ExLS requires a Mk.41 VLS installation which this class of ship doesn’t have. If it could fit Mk.41 it wouldn’t need either ADL or ExLS.As a concept demonstration, great. As a solution for increasing the missile depth on a vessel, no great. For an uparming solution the Exls and those sort of launcher solutions cam provide more missiles for less used space.
Very true, I expect many of these points is why Germany spent 10 months studying and working on this project before they ‘plonked’ a missile launch system on their available deck space.Top weight ALWAYS matters, as the Japanese found out in the 1930s. There is no point in having a very heavily armed ship if it can’t survive weather normally found at sea because its stability is insufficient.
More missiles are fine, but they need to be mated to sensors which enable their use. Arafura, for example, doesn’t have such sensors.
The upper deck of any surface combatant is a very much planned and competed for area. To prevent EM interference between sensors, and such things as unplanned EMF generated initiation of warheads, the whole thing is extremely carefully modelled and the interactions studied. Just plonking something down on its deck is likely to have a number of unplanned effects,which could be extremely serious. That is much less of an issue with something like an LHD; or in the case of the USN an independence class LCS, which have less space constraints (and not the same level of EMR generation).
I think the only Japanese ships with ESSM so far are the AGEIS ships, the MOGAMIs have not yet had ESSM fitted/integrated to my knowledge.Perhaps, but they don’t exist today in an operational state, have they been fitted to a real warship and live fired as IRIS-T now has?

ESSM is not a quick bolt on solution even if you had a few spare adaptive deck launchers in your inventory. Check out the Japanese program to put ESSM on a ship that DOES have Mk.41 for example…
Japan recently upped its ESSM production capabilities. Looks like they are committing to ESSM for other ships. I think previously RAM was their go to.ESSM is now to be integrated on JSMDF “non-AEGIS” ships… Courtesy of X.
Automatic assumption this is for VLS armed Mogamis and perhaps FFM…
LHDs, AOR I believe have 9LV. I thought Choules maybe too, but apparently not..

First 2 JMSDF OPVs due for launch next month, pretty rapid pace with an additional 2 due in March.Crew requirement obviously the key, that's the greatest aspect of the Japanese design, 30 crew for its size is absurd compared to what else is on offer.
Define upgrade. Pretty much the only part that is the same is the rocket body, at least in size. The cheapest part. IF we are going to all the trouble of doing that, the we might as well make more rocket motors, and double our total inventory. As I understand it, the rocket motor is one of the parts we can produce locally.Can the RAN’s stocks of ESSM Block 1 be upgraded to Block 2 level?
It's worth keeping in mind that crew requirements are primarily a function of each navy's operating practices, not a function of technology.Crew requirement obviously the key, that's the greatest aspect of the Japanese design
I thought that Ise & Hyuga have ESSM, as well as the Murasame, Takanami, Akizuki & Asahi class. The old Asagiri class had Sea Sparrow: I don't know if they've changed to ESSM.I think the only Japanese ships with ESSM so far are the AGEIS ships, the MOGAMIs have not yet had ESSM fitted/integrated to my knowledge.
Doe's the Japanese NAVY have their own SAM?
