The submarine world is now undergoing some of the fundamental changes it has seen in the last 40 years and there are signs that those changes may be the biggest, since the order was first given to “take her down.” New technologies are producing capabilities long known to be possible, but not practical. However, with the introduction of superior weapons and sensors, powerful combat suites, capability to launch special payloads like Unmanned Underwater Vehicles and Autonomous underwater vehicles, land attack capability, enhanced submerged autonomy rendered by the combination of an Air-Independent Propulsion system (AIP) and lithium-ion battery (LiB); a conventional sub has now entered the immunity and capacity domain of a nuclear boat.

For nearly a century, diesel-electric submarines relied on constantly charging traditional lead-acid batteries by running their diesel engines either on the surface or later on, while snorkeling near the surface. This left them constantly vulnerable, as they could only hide deep beneath the surface for hours or a couple of days at a time. Over the last few decades, AIP technology has further revolutionized her traditional performance. But now, these platforms are on the verge of yet another advancement; one that will make them return to their original wolf pack roots, relying on diesel engines and batteries alone to go about clandestine business.

As for the AIP systems, the most modern versions like Stirling Engines,........
