Fitting Big Batteries Into a WWII Submarine: USS Cod's Soft Patches
- Thread starter GURPS
- Start date
What the Greenies won't tell you. Since the early 80's our military as well as the USSR were looking for battery systems that would allow for longer than a week. Guess what, they never found an electric source to do that or we'd already be using it.
My bets are on Hydrogen power. The road will be a lot cleaner with the water they will be emitting.
I can hear them now. "but the sea levels will rise."

At the end of WW II Germany was experimenting with Hydrogen Peroxide based propulsion
They did have a hydrogen based internal combustion engine back in the '90s.
The point i was trying to make to all the EV fanatics is, if the Military doesn't have superior battery technology. There's 0% chance that your EV automobiles will ever become reliable.
They US military gave up on battery propulsion many years ago.
Fair Enough ... I was just adding some history about the use of something NOT a diesel engine / Battery Combination
Also I do not see where the Military EVER looked at Lithium-Ion Batteries which were 1st researched in the 1960's with a general break thru in 1974 by a British Scientist and Sony Developed in the 80's and introduced in 1991 ..
Now with the commercial sucess of EV Cars, the future of Busses and Trucks is coming ....
EV busses have been a disaster because of cheap manufacturing and cost cutting as the price of building rose significantly after the contracts were signed, largely because or Covid.
doing a quick search on Li-Ion and military ... there is a flurry of articles in the past 2 yrs, not much before 2020
The Army is now looking at EV Tanks ....
US Army’s Electric Tanks on Hold as Battery Technology Develops
To charge a 50-ton tracked combat vehicle inside the Army’s preferred envelope of 15 minutes, soldiers would need a 17-megawatt charging station—more than 20 times bigger than the largest mobile generator the Army currently has, said Dean McGrew, branch chief for powertrain electrification at the US Army DEVCOM Ground Vehicle Systems Center.
“Ideally, we would be able to go to a full electric vehicle, but currently the technology does not exist to generate, store, and distribute power in a tactically relevant amount of time for the frontline troops,” said Lt. Gen. Ross Coffman, who heads up the Army Futures Command’s next generation combat vehicle team.
Electrification may be possible for support vehicles in the rear, but “as far as large, heavy vehicles that can take a punch and throw a punch, the amount of batteries required to do that over great distances—and the ability to charge quickly—is a challenge for us,” Coffman said.
Do Generals Dream of Electric Tanks?
So, do generals dream of electric tanks? Prototyping a hybrid-electric Bradley was proposed in 2014 and the Army has even entertained the idea of an electric “cannon-vehicle” as far back as 1995 (PDF). What has driven these electric or hybrid powertrain R&D efforts is the promise of reduced energy demand and new capabilities. For example, an extended silent watch mode could lengthen mission times while also reducing heat and audio signatures—and thereby increasing the survivability of the warfighter. These reduced signatures, combined with a smaller fuel footprint, will save lives.
Today's network of acquisition professionals who make up the Army's EV community of interest are familiar with the technology, its limitations, and the capabilities needed by the future force. Service electrification efforts have been, and will continue to be, focused where they provide new or improved performance for soldiers.
Electric tanks may or may not be part of that future force, but a maneuverable direct fire capability doesn't have to be a tank or weigh 40 tons. Whether in a near peer fight, an aid mission in an area of destroyed infrastructure, or a deterrence posture, energy-informed leaders backed by a robust supply network will have the flexibility to act as they see fit for longer periods and over longer distances.
The 80's had Lead Acid and NiCad ... Commercial Li-Ion was not coming until 1991
