I’ve fairly recently started following the Battleship New Jersey YouTube channel and have become quite a fan of the Iowa class battleships.
The plumes on the horizon are the shells landing...

Built by IHC, the bow is fashion really.
I don’t really like these designs.
The company I work for are in the specification process now & I am very involved.
We are favouring something more conventional looking and hopefully reliable whilst still being technically cutting edge where it matters.
Like this:
I will say it’s very exciting to be involved in this, especially as we are essentially clean sheet designing rather than buying off the shelf.
Once we have progress that I can make public I will post here.

Hanson’s new build is a little less extreme but they still went for the fwd accommodation concept with a new fancy bow.
I’m guessing the red one above is also designed to minimise the draft for beach work.
There are pros & cons to fwd accommodation, I’m sure everyone has an opinion but it’s good that the end user is involved in the design of your new build.

talking of bows (and I've probably asked this question before, but can't remember the answer I don’t really like these designs.

).... in 1910 we had the the bow angled forward, 1940 angled back, 1980 angled sharply back and then in 2023 we're back to having the bow angled forward again. Does that mean that the designers of the Dreadnought got their prow design right and subsequent designs were wrong? ISTR part of the answer had to do with how the ship went through heavy seas which modern ships try to avoid (especially those carrying passengers) but...1910

The ram bow typical of the Dreadnaught and pre-Dreadnaught era were only accidentally beneficial as knowledge of how bow waves interact with hulls was either only theoretical or hadn't yet emerged.
Positively raked bows, generally with flare, provide seaworthiness by giving a rising waterplane area(gives rising buoyancy) as the bow plunges into a wave and deflect water away from the deck.
Plumb and negatively raked bows give a much softer motion in heavy seas as the water plane area either stays the same or actually reduces as the bow enters a wave, at a cost of the motion being greater in magnitude and needing more freeboard.
The steep reverse rake of Zumwalt etc are mostly about radar cross-section reduction although they also affect seakeeping.

No pictures, as I was WAY too far away for anything taken with my phone to make visual sense, but...
Yesterday I was walking up on St. Catherine's Hill, inland from Christchurch/Bournemouth, and I spotted a naval vessel leaving the Solent via The Needles. Too late to check it on ShipRadar (or whatever it's called) I resorted to... the https://solentships.com/recent.html ...and discovered that the only naval vessel large enough to match what I saw yesterday was listed as...
Until I checked online I thought it might be one of the Type 45s leaving Portsmouth, but the only other naval vessels in the movements list were River Class patrol boats and a Mine Countermeasures ship (HMS Hurworth M39). Looking at images of the Louise-Marie I can see why, from over 5 miles away, I could confuse one for the other... https://en.wikipedia.org/wiki/Belgian_frigate_Loui...

F931 LOUISE MARIE, has left the area via The Needles.
I saw it first east of Hengistbury Head between Christchurch and the Isle Of Wight, then it steamed west and disappeared behind the headland (and took it's sweet time) to reappear toward the horizon directly above Christchurch Priory as I looked at it. I'm rather annoyed now, as my alternate walk would have had me atop Hengistbury Head at that time of day, and I usually take my DSLR to try bird/wildlife photography when I walk there...F931 LOUISE MARIE, has left the area via The Needles.
