Just saw it here…
No.
It’s a submarine missile launch, I guess somebody just edited the F-15 in over it.
You know, the page you linked to has numerous comments from people stating that it is obviously a fake video…
Also, if planes could be launched that way, why would you need those big, expensive aircraft carriers?
Of course, the most obvious tipoff is that the plane is a USAF F-15. If it was real, it would surely be a Navy F/A-18. 
In any event, omgzebras is correct, of course. It’s a missile launch with an F-15 photoshopped over it.
I just saw a promotional video a few days ago about a planned UAV that would be submarine launched. I’ll try to find it.
Nevermind. I think that project never really got off the ground (so to speak).
There have been submarine aircraft carriers. The most famous is the Japanese I-400 class, three of which were deployed but Japan surrendered while they were en route to their first planned attack.
AFAICT, all the examples used aircraft that launched from the surface after the submarine surfaced.
DARPA is currently accepting designs for submersible aircraft.
Huh, wasn’t there a Clive Cussler story that featured one of those. I just figured he’d made it up.
It is obvious, of course, but just about any YouTube (or similar) video will have a dozen comments claiming it’s obviously fake. 
It’s faked. If you look closely, you can see it’s a Navy jet. Currently, the only operating underwater air base Is the Air Force and Air National Guard base under Lake Caddo, Texas.
Yeah, that’s precisely what we need these days. We need to be focused more on how to get strike teams into and out of position very quickly.
Well, the same converted Ohio class boats that would be able to launch the Cormorant type UAVs for recon would also be able to deploy SEAL delivery vehicles for strike purposes.
Sometimes common sense beats knowledge
You do realize that my comment was a joke, right? (Hence the “winking” smilie…)
One of these two statements is wrong. 
Come on, is your main problem with my factual accuracy in that post really the misidentificaton of an Air Force jet?
It wouldn’t surprise me if such a thing does exist at the moment. One of them super-secret project things.
That’s Caddo Lake. And who told you about that base?!
Here’s another fine submarine-launched flying thing: SSM-N-8 Regulus - Wikipedia and http://www.youtube.com/watch?v=-RjyjyvG5W0
Yes, of course. And of the funny type, IMO.
