Military recon powerboat concept

These are some conceptual sketches I did for a project im working on testing out stealth capabilities with a twin turbine set-up for national security. its still at its primial stages but a model should be underway next month. thats all i can really show u guys. any idea's, questions or concerns lemme know. thanks guys

I have a stealth hovercraft design, just sketches and non-working type models.

How the heck do you getting someone interested?

Someone mentioned that stealth for the Coast Guard may not be a great idea because boaters may run into them with having no or little radar signiture........just one of those comments you get.

I'm interested in seeing what a CCS person can do (College for Creative Studies in Detroit). I went to Lawrence Tech and U of M, often wished I followed my heart and went to CCS.

That's another possibility, it's sure no unmanned vehicle which is something really getting attention these days and more feasible at many levels.

Could be one of those "let's see who I can fool" things. I sure hope not, that would just piss me off.

Wellll.....It looks to me that he needs to do a TLR investigation into the capabilities of the sensors that he wants to be "stealth" against. Right now, the only armed forces that this thing is "stealth" against is a blind deaf caveman with a rock.

Edit to add....Then again he may be working for Northrup Grumman to do a design for the Coast Guard.....

It was Lockeed Martin, but I got the joke.

All he has to do is leave the navigation lights off and paint it black and it's stealth, right?

EDIT - both half right:
Coast Guard Fleet fiascos
Quote:
Instead of doing it piecemeal, the Coast Guard decided to package everything, in hopes that the fleet would be better integrated and its multibillion price would command attention from a Congress and White House traditionally more focused on other military branches. And instead of managing the project itself, the Coast Guard hired Lockheed Martin and Northrop Grumman, two of the nation’s largest military contractors, to plan, supervise and deliver the new vessels and helicopters.

The NAJA 12 ASD has a stealth effect.
The 2 annexes and the inclinations give no signals on radar.
Speed = 50 knots

That may of started with stealth in mind, but they slacked off on some of the details if you ask me. Still I don't recall seeing that one before, looks a lot like my hovercraft design - thanks.

My hovercraft design does not have all the stuff on it either as it's just an idea right now. In fact being "passive" is a big parth of the electronic stealth aspect. I image swarms or pods of UAV's as the eyes with active signals, and the patrol craft feeding off of the information beamed to it.

I agree with kach22i, there are some things in that photo just jump out at me. An awful lot of low signature is in the details, not the large panels. Did you know that one of the major identifiable signatures on some targets are the operators mirrored sunglasses?

On the topic of this thread, I dont see the feasibility of this design, besides the obvious, is this craft to be jet turbine driven. By using the turbines thrust? If so, I think thats pretty inefficient and not proven as a design. Besides those after burners have a bit of a heat signature. The craft could be turbine powered, but imo it would have to be prop driven. That's the only way I've seen it work, like the world record holder for offshore racing. This boat over 200mph, with turbines, but with props. Not to mention how do you steer it? If its with sub surface rudders this further, reducing the need for the use of jets. You need thrust vectoring or something, but still jets big enough to propel this thing with thrust would burn a ridiculous amount of fuel and make the boat imo prone to flying rather then skimming.

Also, this boat is merely for scouting? I hope so, otherwise theres no way of production, unless it has some tactical weaponry. I mean you can even go out on the deck to shoot or apprehend people.
I'm not try to rip apart the design, but we werent given hardly any info, so I have to assume some things.

I could see this craft with twin apache turbines, twin surface piercing shrouded drives, with the hull protruding over the drives, to further reduce spray. Maybe throw in a hellfire missile launcher, gattling guns and cruise missile launchers. I'd buy that

That would be useful on the Solent for the Rag & Stick brigade....

That's right out of the old "Mortal Combat" movie.

It is!

The problem with high speed craft is letting them know you are coming. A giant roostertail of water shows up pretty good on radar I hear, and can be seen from a distance.

I made my first comments without seeing the images, he had a double post, one post had no images.

I guess it's just a fun ride to post bogus images for some people. Nice renderings even if they are not thought out very carefully.

Stealth my ass.

With the turbine outlets in the rear you have a heat signature big as a smal european country.

I would go for the same concept as KNM Skjold.

They use skirts like a howercraft betwen the hulls and let the exhaust out there.

Well I didnt say it would be stealth, but it would be a lot more stealth than jets sticking out the back. Either way, think of the noise, look up the Callan
racing boat on "you tube". The thing is unbelievably loud. Fast but my god I'd hear that that thing coming, the only stealth might come from not knowing it was a boat, thinking it was an F-14

btw I must have missed that part of mortal combat, I saw but only kinda saw it.

Remember as has been said above stealth ain't just about low radar signature! People got ears and can use 'em so you need QUIET engines (USof A don't do quiet ), no wake and no heat! When to use matters too! Little bit of rough weather and its a submarine - straight to the bottom!
