The U.S. Armed Forces operate a wide array of sophisticated weaponry, in many cases superior to anything else in the world. But while the new destroyers, carriers, or the F-22 might have no equal, the U.S. Armed Forces face a significant gap in their capabilities: the total lack of any conventional submarines.
The United States hasn’t produced any conventional submarines since the Barbel-class in the late 1950s; every submarine class since then has been nuclear powered. This might have made sense in the context of the Cold War, where Soviet nuclear-powered ballistic missile submarines had to be shadowed, but times have changed.
While previously conventional submarines had to snorkel roughly at least every two days of time under water to recharge their batteries, air-independent propulsion (AIP) has changed the game. German Type 212 submarines can stay under water without snorkeling for up to three weeks, traveling 1,500 miles (2,400 kilometers) or more. Without emitting heat and with no need for constant cooling due to the lack of a nuclear reactor, these German submarines and comparable designs are more than a match for nuclear-powered submarines in terms of stealthiness.
Whereas the Soviet Union had submarines cruising the globe’s waters, the next big naval challenge for the United States isn’t a revitalized Russian navy, but the People’s Liberation Army Navy’s subs and ships lurking in the South China Sea and East China Sea. These submarines could play a key role in trying to enforce China’s A2/AD (anti-access/area denial) strategy against a superior USN, with the goal of preventing the United States from intervening in any conflict involving the Spratly Islands, the Paracel Islands, the Senkaku Islands, and Taiwan.
With the PLAN’s mostly conventional submarine force, the USN’s superior anti-submarine warfare capabilities will continue to severely hinder any Chinese submarine operations outside the first island chain and outside of China’s land-based air cover. This limits the theater of operations to a high degree and puts it well into range for conventional submarines using only their AIP based in Okinawa, Singapore, Subic Bay, Guam, or possibly Zuoying Naval Base on Taiwan.
Whereas China can and will create a bigger subsurface fleet than the USN by mixing conventional submarines with nuclear powered ones, the financial burden of matching hull with hull is practically impossible for the United States, at least as long as it limits the USN to SSNs. Conventional submarines might change this.
While one Virginia-class submarine costs roughly $2.7 billion per unit, the same money could buy six to seven conventional submarines of the German Type 212 class. While U.S. nuclear-attack submarines are superb, many examples have shown that sophisticated conventional submarines aren’t just a match for surface fleets but also for older SSNs under the right circumstances.
In case of a conflict with China, the majority of naval combat will happen well within the first island chain, where a purely nuclear-powered fleet seems like a waste of assets. Neither their range nor their speed will be needed in most cases. As conventional submarines will be able to handle most tasks, the dramatically more expensive SSNs could stay out of the first island chain concentration on shadowing the PLAN’s SSBNs and SSNs outside this area, while keeping enough in reserve and out of harm’s way to maintain a credible deterrence against Russia at the same time. Additional conventional subs would also prevent the projected sub shortfall starting in 2021.
But going back into the business of building conventional submarines for the USN wouldn’t just make sense from an fiscal point of view for a navy that has limited resources. It would also offer various economic and political options for the United States.
President George W. Bush promised Taiwan eight conventional subs in 2001, which were never delivered. If the United States were to start building conventional submarines again, the pledge to Taiwan could finally be fulfilled. Moreover, the market for conventional submarines is gigantic. Most Asian nations are looking to establish, increase, or modernize their submarine fleets; Germany and France have both enjoyed particular success marketing their submarines to countries like South Korea, Indonesia, India, and Malaysia. Many of these nations are close U.S. allies or friends. The market for modern conventional submarines built in the United States would probably amount to several dozen hulls within the next two decades.
Built in the U.S., employing U.S. workers, and spreading the development costs over ever more hulls, Washington could seriously consider subsidizing some of those submarines for navies which are direly in need for a naval deterrence against an ever more aggressive China. If the United States doesn’t want to hand Asia over to China on China’s terms, a price might have to be paid in the end. It’ll be either money or blood. Subsidized submarines for the Philippines and Taiwan might just be what it takes to show the steadfast commitment for the status quo and the support for those two nations, which are under heavy pressure from the Middle Kingdom.
Conventional submarines with AIP wouldn’t just bolster the USN’s capabilities in this crucial theater for a comparative bargain, they would also allow the U.S. to enter a sizable weapons market while giving it the power to supply precious allies with exactly those tools they need for deterrence. The technology transfer necessary for building subs like the Type 212 could very easily be attained by a joint venture or even licensing the German subs from a company desperately looking for sales like Howaldwerke-Deutsche Werft (HDW).

It’s just a guess but IMO we very likely have small, stealthy drone subs.
No idea if such drones can replace the utility of quiet conventional subs.
trump should sell this idea to PA and the rest of rust belt
My Uncle Ron was on diesel subs during the Vietnam War. They did things that nuclear subs could not be used for. In some ways it seems strange that the Navy stopped using them.
How would we control them remotely? Satellites? Isn't signal and power degradation a problem underwater?
Slow comms via sound and ultra-low-frequency rf.
When faster data is needed pop loose a tiny transponder to float to the surface with a thin tether of optical fiber back to the boat. The rf device would only need to be the size of a marble... data transfer via the large NRO satellites in geo orbit 23,000 miles out. Power output from the device would be far less than a milliwatt since the big NRO birds can hear anything and so nearby ships would be less likely to notice the signals.
Anyhoo, that’s my guess as a computer and radio geek :-)

If it's about batteries, I bet Tesla is behind this new interest in conventional submarines. If it is about (politically-favored) Tesla, then funding for conventional submarines will go through Congress faster than Donald Trump can insult a competing candidate, especially if they guarantee that GE gets part of the business.
Long wave radio may fare better..
It was called high tech for the sake of high tech. Everything had to be high tech.
We need convention AC carriers too. Waaaay cheaper to build and operate, same offensive punch and same mission capabilities. Damage control is much easier on a conventional ship.
Interestingly enough, the sub my Uncle was on collided with another sub during a drill. The captain did the wrong thing and surfaced immediately. If one sub had been over the other sub, this could have caused one or the other or both to sink. This mistake cost the captain his job. The dent went all the way through the super-structure to the interior of the sub. Afterwards a sizeable percentage of the crew were so shaken up that many were allowed to transfer out.
My Uncle was happy that since he was a cook, he was allowed to shower frequently. Because they carried a limited amount of water, the rest of the crew was often not allowed to shower for extended periods of time. He was also quite pleased that every month that they went into hostile waters in Vietnam to support special forces or for reconnaissance he got bonus “combat pay”. This was in addition to the extra “hazardous duty” pay he received for being on the sub to begin with. I forget how long he was on subs, but I know it was most of his career in the Navy... I think about eight years. I will have to ask him about it again soon; he is getting old enough that the story of his service could be lost.
They managed to sneak a few of those back into the fleet. Compare the World War II Wasp (CV-18) to the current Wasp (LHD-1)
Length 872' -- 844'
Beam 93' -- 106'
Draft 28'7" -- 26'5"
No angled flight deck and no cats.
When I was stationed in Okinawa running a Mike boat I had to meet a diesel boat and pick up a crewman with an impacted tooth. I met it in the ocean and the man was transferred. When the hatch was opened the stench was awful.
The purpose of a conventional fleet is to manage costs. If you try to make them like the supercarriers, you end up with a Kennedy. Most of the costs, none of the benefits.
Same reason that the conventional subs need to be small coastal defense models. If you want something that looks like a Virginia or an Ohio, go ahead and drop a reactor in it. If you want something that looks like a Bush or a Nimitz, go ahead and drop in a reactor.
"Just what the Hell did Obama do??? I thought you GOP guys were supposed to stop this nonsense?!"
The U.S. has two shipyards capable of building subs - Electric Boat and Newport News. In order to build conventional subs they would have to stop or slow the building of nuclear subs. Is it worth it?
