NATO ASW Design Challenge

I wouldn't expect less from you, Jabba!

[Charybdis]

Very nice drawings

[TimothyC]

I decided to start from scratch,

That's too bad, I like the design that you've started, the only thing it's missing is a Crotale launcher.

I am done. Ace, can you update the first post?

[TimothyC]

I can barely read your B-side, and you've got the crediting backwards.

[bezobrazov]

...and, just out of curiosity: what exactly am I being credited with? I must be getting old, since my eyes cannot detect it...(I don't mind being so, since your design is a really nice one, but fair should be fair...)

The ships would have most likely taken part of the place of the Spruances. (some of) the Spruances would be converted to Kidd types, as was originally planned.
These ships are ideal for keeping an large area of ocean covered with relatively few ships. I designed them along the lines of the Perry class, as I had done a lot of research on those. This ship came out entirely different though, as you can see.
An drawback of the propulsion system is the cost. The only way to cut cost…. Was to cut other systems then the engines. In this case: the radars. This makes the ship unable to do any other role then ASW. For the same reason I chose the perry’s sonar.

Well, please comment. I certainly know this is not the best design for an ship like this, but I just wanted it to be different. And well…… I think I got that covered

Gun fired depth charges? Interesting idea.

I have been curious about this since your Oliver Hazard Perry update - what are the grey semi-circular devices near the bottom of the hull? Is that some sort of retractable stabilization system? All in all a very impressive concept and obviously well thought out. The concept of the "nuclear frigate" is an interesting one, I wonder if they would have remained in service or been phased out in the defence cuts following the collapse of the Soviet Union?

Cool water intakes. The Perry was the first hull that I've seen the actual location info for such details on the internet, and therefore is the first use of it on a shipbucket drawing.
