The RCN will be recieving two more ships from the RN in 1945; Hood and Majestic

Working on adapting the Hood's current fit to my art style;

Looking mighty fine in the ShinRa style too. 8)

I'm not sold on the helipad, but that's a complaint I have about all such RCN ships so equipped.

Seems somewhat early for a helicopter pad - and I'd reckon it's far too small as well.

Plus you have to make sure you don't hit the AA guns on X turret as you come in, not to mention the turbulence off the mainmast and the funnel gases...

Post-WW2, they used the top of turret II on Missouri as a helipad, since the quarterdeck was still full of gear; not exactly a large space. The pad is there to accommodate a visiting helicopter, not operate one, really; there's no real way of getting one from the pad to the existing hangars and support equipment.

Trying to put a pad on Hood's quarterdeck does not seem feasible, both because of it being a much narrower stern than, say, the Iowa's, and also due to anecdotes of Hood's quarterdeck being submerged at high speed.

66

Tuesday, May 6th 2014, 2:53pm

Iowa's triple 16" turret has a far larger surface to mount/use as a helipad compared to Hood's twin 15" turret. Furthermore you have an AA mount to make it even more difficult to land a helicopter in an area barely large enough for her rotors to not clip anything. Toss in a pitching, rolling ship with winds and funnel turbulence/smoke and I smell a crash landing on the very first attempt to land. If the pilot survives I doubt he'll have much better luck on the second, third or even tenth attempt.

The pad is not on Hood's turret, I just mentioned the Iowas as a reference

I see nothing technically wrong with the design, but I do feel that a 140mm weapon for this class of warship is rather overkill. I believe you would be better served with two twin 4in mounts of some sort.

Minor nit (as it has no effect on the design in SS). I think that your Polar 5 type with a waterline length of 269 feet is going to have a length overall that is a lot more than the indicate 272.53 feet...

74

Monday, November 17th 2014, 6:40am

Yeah, simming icebreaker type bows seems challenging, especially considering the way they tend to have a 'knuckle' above the waterline and all that.

Speaking of;

75

Monday, November 17th 2014, 12:14pm

Well it is never easy to calculate that. With a picture, I usually add how much the stern sticks out first and fill that into SS, then calculate what the overalll length of the ship is using the picture and finally adjust the angle so I get that overall length.

But regardless of the bow angle, your ship does have a stern overhang and you have set that to 0.

76

Monday, November 17th 2014, 2:15pm

The 5.5in auto is probably overkill for the sloop, if it works it'll be a formidable gun but its probably pushing things for a 1945 design and the gun is still experimental.
The 4.5in version is more traditional and probably just as useful and able to defend itself against most threats.

77

Monday, November 17th 2014, 4:55pm

"There is no 'overkill.' There is only 'open fire' and 'I need to reload.'"

To me, size-wise the 4.5" turrets somehow look better on the design and because Hood stated that the 5.5" turrets are still experimental, I would think that the 4.5" might be the better option at the moment. Perhaps later when the 5.5" gets out of the experimental phase, you could build an "Improved River class" batch of ships if you really want that gun on that small boat.

Another thing that just occured to me. Do you think that 250 rounds per gun is enough for a 4.5" automatic gun? Not sure what the rates of fire are for the 5.5" and 4.5" automatics.

78

Monday, November 17th 2014, 6:08pm

The sloops may not be in production for another year or so, hence the newer gun depicted. Reverting to the current gun is also an option;

Rounds per gun isn't great, but it's not much less than the full-size fleet destroyers I have. The current gun runs in the 12-15rpm range.

Stern overhang, like bow overhang, doesn't seem to affect the sim report at all, which is why it's one of those settings I frequently overlook.

Rounds per gun isn't great, but it's not much less than the full-size fleet destroyers I have. The current gun runs in the 12-15rpm range.

Considering that it's an automatic, I was expecting something in the 300-400 rounds range for the 4.5" version.

Stern overhang, like bow overhang, doesn't seem to affect the sim report at all, which is why it's one of those settings I frequently overlook.

That is why I said it was something minor. It has no effect on the sim of the ship, but it just looks better when you look at the picture first and then read through the sim report. :)
