[ooc- Please comment, folks!]

The Elijah Defensive Perimeter (DP) boat is an original approach to a common problem: missiles and torpedoes. As much as we hate to think about it, in war, we take hits, and now we have found a way to decrease the damage done to our naval fleets. The Elijah is a boat that can counter missile and torpedo attacks.

It is armed with two CIWS’ to stop missiles, and has a unique torpedo defense system—Anti-torpedo measures can be jammed or evaded, but this defense can’t: Solid steel plates. These plates are attached by steel chains to the side of the boat (beneath the waterline, to decrease weight). The chains’ reach is about 2 meters past the bottom of the boat, and the plates themselves reach 35 feet down. No matter how many computers guide a torpedo, it can’t get through solid steel plates.

Specs:

Length: 50 feet
Beam: 10 feet
Draft: 9 meters
Crew: 4
Chain length: 3 meters (1 meter from bottom of hull)
Propulsion: 3 300 horsepower Mercury motors
Speed: ??????????? (ooc- imput please)
Armament: 2 CIWS
Displacement: 57 tons
Hull: 3 inches of steel and Kevlar
8 plates per ship

Steel Plates:

Thickness: 1 inch
Width-2 feet
Length-35 feet (ooc-is this overkill?)
Positioning- Staggered on either side of boat
Weight- 548, 868 lbs. (out of water)

[Note: For the Elijah to provide the most protection, many should be bought to surround the perimeter of your fleet.]

The armor aint anything special... :P A torpedo going 50-7 knots can probally easily blast through a good portion or all the wa and then the explosives would take care of the rest. I woul do some more research on new AMerican ships that are coming or have come out, such as the CVN-21 or the DDX. Like I pulled the armor configuration for my submersible carrier off the CVN-21 design and made a few modifications. Also they're better ways at stoping torpedos you just have to do some research.

Also what about SAMs? If it's suppose to stop missiles I woul put some SAMs on it...Also look into something called Metal storm.

Oh yea 1" thick steel plates isn't much I said before. Ididn't see the thickness until now...hell a German Torpeo from WWII could probally blow through one inch of steel. I think Batte shis in WWII hadlike 12"s? idk I might be wrong on that I forget...

Also how are you "jamming" the Torpedo?

You can hard-kill torpedoes with other torpedoes or underwater warfare rockets (like those the Russians use), decoy them with systems like Nixie or noisemakers, shoot at them with underwater cannon turrets (only at low speed if you like realism), and other means. Unfortunately, the ships as designed would not be able to operate at fleet speeds, and the best protection against torpedoes, other than what I mentioned above, is speed.

Oh damn you....You're suppose to get the newbie to THINK nd get off his ass and do more research. Bu noooooo you just go and tell him all the goods...

Frst off you don't shoot full size SuperCav's at torpedos. The SperCav was a weapon originally designed by the Russians to fire at American subs so that it would hit there sub first. Now what's the pointof this? Sure it seems silly to hit the other one first when your both going to die but that's not the case. Many tordpedos have a wire between them and the ship for more accurate guidance thus if the American sub wants to live they move out of the way of the SuperCav but they break there wire with there torpedo.

Now what you're thinking of is A ASHUM gun system. Basicly it's an under water CIWS but instead of firing coventional type of bullets i fires 30-mm or w/e mm you use of SuperCav "bullets" I uess you could say. Another method of hitting torpedos are with "mini-torpedos" or w/e they are I don't know that area very well.

Also for an engine I wuld usea diesel engine or maybe adiesel/electric hybrid engine. For larger ships I would use a Pebblebed Nuclear reactor, much more efficent then current American ones.


Now yes Noisemakers can "jam" SONARs but it all depends on what type of SONAR system the enemy is using. For example I use the Poseidon system from Macabees and that has been made to beable to ignore noise makers and such.

As I SAId before I would add some SAM's to it.. Maybe something like four slo SAMs and four SAM systems at a 90º or like 110º for shooting down Sea skimmers.

sorry for any weird spelling mistakes or w/e..... It seems my wireless key board doesn't like me so it wont put down all the letters I type sometimes.

Nah, the underwater warfare rockets I was thinking of are the RBU mortars/rocket launchers and the like on surface vessels rather than the Shkval and its kin. Basically, the RBU-fired rockets saturate the area before the torpedo with either noisemakers or depth bombs that either decoy, damage, or destroy the torpedo. Low cost anti-submarine weapons such as those Russian rockets can be quite effective, and cheap. As for torpedoes that can perform hard-kills, there is the European MU90 and I think the American Mk.50 can perform hard-kills as well (though I might be wrong there).

ASHUM was precisely what I was thinking of regarding underwater cannons. Again, it's a low-speed defence and can't really be used at fleet speed.

ahh I've never heard of the RBU thing I'll have to look into it some more.

:P I think you mean Flank speed....I don't believe there is a "fleet" speed in the Navy.

The RBU...can that be used for torpedoes or just subs? I can see that you can set the fuse and hen shoot them, but how effective is that? Also, if the plates were changed to a foot thick (is that enough?), it's weight would be 862,400 pounds (all eight pieces). And What motors do you suggest?

As I said you should look into some newer amerian ships an pull some ideas of them. The CVN21 has I nice armor layout that I use for my submergeable carrier.
