Looks like a dumb shape for an underwater vehicle, until you understand how it achieves propulsion.
It has some level of relatively low power buoyancy control (think, battery driven internal air bladder).
As it travels upwards from positive buoyancy it can also travel forward using its fins - probably like a 10-1 ratio of forward to upward if designed properly.
The same would be true in reverse by reducing its buoyancy.
The forward motion in the water can also be used with an impeller or other vampiric rotating device to power a generator, so it can overtime recover its charge.
This last part is speculative, but I imagine its upwards and downwards motion through the water, can also be timed along with the natural heating and cooling, day-night cycle of the ocean, and the accompanying slight change in water density, to maximize efficiency of the effects of the buoyancy.
An ocean glider is an autonomous underwater vehicle used to collect ocean data. [Or commit CIA mischief / horrible crimes]
The glider illustrated in this animation is the Slocum glider. It may look like a torpedo, but it doesn’t have propellors or an internal engine. Instead, it uses a pump to gently change its buoyancy over time. This allows the glider to slowly move up and down through the water. And as it does so, the big fins sticking out of the sides of the craft create lift to propel it forward. It’s similar to how a glider in the air works, except the ocean glider can glide up as easily as it glides down.
Btw, fuck DARPA, they funded and probably continue to fund companies that track Americans they don’t like and intentionally manipulate the outcome of elections including fucking over pro-2A patriot Roy Moore, the Former Alabama Supreme Court Chief Justice.
Probably has a use, but the design is not very practical for depths.
The narrow wings do not look like they have much support, either in payload or structurally, and high pressures will find weak points in shapes like that pretty quickly.
Even if the wing areas are equalized with sea pressure, it is difficult to see a really good use for the wing shapes.
The most efficient volume to surface area (and able to withstand pressure) is a sphere, and the next most efficient is a cylinder, which is the shape of modern subs. Why the vast departure? Is this some sort of design based on the Iranian claims of 400kt torpedo technology?
No information on what depth it is rated for. I suspect the shape is to achieve a certain appearance on sonar. The wings may well be solid (not hollow) aside from the buoyancy components.
