NATO ASW Design Challenge

[Clonecommander6454]

ASW version: you might want to change the aft arrangement a bit, right now the hangar looks cramped
AAW version: doable, even likely, apart from 1 point: when you have LW-08 available you also have DA-08 available, those work better together. you also might be able to move the mk 13 a bit more towards midships, but that depends on your belowdeck arrangement.

I followed most of the Electronic Suite onboard Kortenaer Class and Jacob van Heemskerck Class so I think I can keep the electronics as what I currently have. The goal of these two design is to keep the Electronics and Hull design mostly the same to speed up the building process in war time, so I think it might be better to keep similar electronics suite although they might not be the best. I agree that the hanger might be somehow cramped. But when Oliver Hazard Perry Class can have a double hanger in the width of 14m, and the ships' beam is 16m, I think that removing the 40mm gun will solve the problem.

the fit I described (both 08 types) is what the heemskercks have
the hangar fit all depends on the type of hangar: the perry has 2 separate hangars for these 2 helicopters with control and maintenance in between, you could make an single one in which they both fit... which gives you an minimum beam of 12-13 meters. you have 16, so you have 1.5 meters space for guns at each side.... check out of that works

Well as this is my first modern warship, I have no idea really where to go with it. Here's a rough idea of what I've got at the moment;



So far the only things I know is that she'll have most likely exocet missile launchers amidships and an OTO Melara 76mm on the foredeck. Whilst she'll have a small landing platform aft, no hangar facilities will be available as far as I can think. Propulsion would be twin screw CODAD. Other than that I have no idea what I'm doing. I don't even know what weapons are out there today that are Anti Submarine. As I mentioned earlier I've never drawn anything post-WW2 so I'm unfamiliar with systems, weapons, layouts, etc.

And yes it is a small design designed to be cheap to produce and maintain.

The main problem as we've discussed in the Type 14 thread is that it's so small it's going to have a hard time executing its mission properly. It's got a small sonar and likely very cramped conditions for an already small crew. It's sonar is pretty small-looking too. And in the end even the escorts specifically designed to be cheap to produce and maintain weren't due to machinery and electronics/sensors.

Nicely drawn ship though, it would be an appropriate light frigate for corvette for a smaller navy along the lines of the Italian Lupo.

Clonecommander6454's ship strikes me as being a proto-MEKO 360 which is the closest thing to a NATO-standard frigate built in real life.

She's not done yet but i wanted to post the almost finished version for some backup so : burn that fire!

[Hood]

Made some changes, added some extra gear which was likely to be added and details and some blast shields for the after Sea Wolf. I think the hangar is too high for a Type 22 approach so I've left it as is for now.

Then my sources are wrong. I think I have to remove the gun because the gun is 9 Feet wide each. I will be moving the SVTT to there instead. Changes will be completed soon

Oh yea, Phalanx or Goalkeeper?

[MC Spoilt B'stard]

Oh yea, Phalanx or Goalkeeper?

I would go with Phalanx due to the deck penetration of the goalkeeper, and phalanx doesn't have that ''problem''.

@Hood : is that Seawolf launcher beside the hangar suposed to be there? i realy dont think it would fit there ! and it would have a crappy cover.

Yeah I agree that she would be fairly small and cramped at this side and probably not the most capable but indeed I was thinking more in terms of an oversize corvette to an aviso style vessel to fulfill these requirements (though the displacement I'm guessing would probably be around the 2,500 at full load and not 3,000). Should I continue with this design or start afresh? I suppose it wouldn't be too hard to either replace the sonars or even just stretch the hull and move the midbreak further aft to give that larger ship feel.

I suppose it's a habit I have for drawing the smaller vessels as I see compact designs being far more efficient and cost effective than larger designs which are likely to have systems not needed to fulfill the basic requirements.
