Here's some very cool and exciting news in the field of military science and technology. Two conventional submarines have just been commissioned and are considered to be virtually invisible to sonar. The subs are "driven by air-independent propulsion. The use of fuel cells markedly increases the sub's radius of action. Hydrogen and oxygen combine in the fuel-cell module and are converted into electricity. Water is the only waste product that remains. This cutting-edge propulsion system enables the ... submarines to move virtually noiselessly underwater, thus making them very difficult to detect."
Awesome. The subs are designated ... U212A ... and are made ... in ... Germany ... Uh oh.
