Well keep shooting naval gunfire support when a gun turret has a mechanical failure is one thing. If you read a bit about naval coastal operations like Operation Seadragon in Vietnam and the Falklands War you find that this is a major issue. NGS is carried out for hours not just a single shot or two and mechanically reliability is a major issue. Two gun turrets also doubles your rate of fire when both are working. And they enable you to keep shooting at any target no matter how you have to steer your ship.

Well it’s a WIP and I haven’t drawn in the air defence system because I haven’t worked out wether to go with VLS or a trainable launcher. It does have two turrets for twin automatic cannons in the 35-45mm range so is not helpless against air threats without the SAMs. Anyway most navies that are bombarding other peoples coasts tend to have support from their own carriers and the like. So air defence is not a major issue otherwise it would be a 5,000 ton ship with a big missile system.

Here is my finished version.

[ img ]

Armament is:

2x 105mm gun turrets (fore and aft)
2x twin 35mm gun turrets (fore and aft)
2x eight cell Mk 41 VLS (SDSS size, port and starboard)
2x twin 324mm torpedo tubes (port and starboard)
4x six barrel 7.62mm Miniguns (each quarter)

The VLS can carry 32 ESSM radar guided missiles and 32 Delilah trimode guided long range surface attack missiles using quad packed canisters. Radar fit is the CEA CEAFAR search and tracking radar and CEAMOUNT illuminators for ESSM. The flight deck has no hangar but can refuel and rearm shore based helicopters.

Edit: Update from 'clean' to finished.

when it has no hangar, the helicopter shouldn't be showed landed on the deck. speaking of the heli: what type is it? I've never seen it before, it looks like an bell-kamov design :D

Minor netpick from the newbie, TurrentHead, but your right hand landing strut for the landed heli is missing from behind the railing, only the left one is visible. :)

Also, I am interested as well. What type of heli is it?

The helicopter is the AVX Aircraft Company upgrade proposal for the Bell OH-58D which I uploaded to the Planebucket thread a few weeks ago.

viewtopic.php?f=16&t=47&start=0

http://www.avxaircraft.com/technology.html

I drew the helo landing side on because the flight deck is of short length and designed for this helicopter to land that way. Even though the ship doesn’t hangar a helo I thought it would be worth drawing in to show that it is a non standard flight deck.

It is just an optical illusion that the left landing strut is missing. Because it is only one pixel wide it aligns to the one pixel wide part of the railing mesh and disappears. I moved the helo around quite a bit but one of the struts kept disappearing. I might redraw the struts so they are not where they should be on the aircraft but so you can see it through the mesh. Or I could just draw the helo coming into land so it isn’t on the flight deck and the mesh won’t be covering the struts. Win, win?

Ok here's my view of another 98mtr Basic design concept using rifleman's basic hull form. I've redesigned/remodeled the superstructure however to follow very closely along the lines of other proven designed and built Vosper Thornycroft naval frigates and corvettes in service with other navies. This concept being in the mid-late 90's era

So far I prefer Squizzy's design on the original concept. Fot a start the hull is a better shape for that size; and he's concentrated on a getting the best fit without a helicopter capability. It would suit navies with shore based air support.

PB!
Seeing your post here made me wonder if you have seen my take (end of page 1 of this thread)

Thanks for your comment PB! The design does fit in well in the high end Green water/ Coastal-Littoral operations role with a limited Blue water fleet escort capability.

Wrong pennant number. this class of ship should be either F (frigate or escort) or P (patrol craft).
The letter C is reserved for cruisers
That's very true under the NATO & Royal Navy ships letter Designation system. The Letter "K" is reserved for use when classifying the "Corvettes" unless your either the Armada del Ecuador (Ecuador Navy) or the Marinha do Brasil (Brazilian Navy). Ecuador does use the letter "C" designation in identifying the Corvette in that navies service in which they currently use the letters "CM" meaning "Corvette Missile" while Brazil on the other hand use the letter "V" to identify the corvettes in their Naval service.

The reason for my remark about the penant number was the fact that Bombhead drew his version with the White Ensign, which in my eyes means Royal Navy, and in that time scale C is for cruisers.
during WW2 K was for various anti-submarine escorts, namely Flower & Castle classes corvettes, River, Loch & Bay classes frigates, while cruisers did not carry their penant numbers at all.
