Pede propulsion!

Seriously, though... How can I tell if this is legitimate? The blurb came up on a Google feed and it seems they already removed it. (I did screenshot it jic). In looking at the "Naval News" site it looks like the other stories they offer have backup from other sites (eg- reported widely). So it doesn't "seem like" they're a hoax site, seem to be seriously into naval history, etc, but then looks can be deceiving and it IS AFD after all...

Edit: It can still be found in Google News by searching for "submarine".
