Can Sg incoming subs endure up to 30 Days under the sea?
Compared with
Germany 212A Class
The 212A Class submarine stands out due to its significantly
longer diving periods than with all other conventional submarines.
The longer diving periods are based on a new kind of propulsion
system that is not dependent on outer air. In a chemical process,
fuel cells convert oxygen and hydrogen into electrical energy. The
power produced in this manner provides the propeller engine and all
electrical systems on board with energy during the submerged
operation.

2.How long of submerged endurance of Type 214 with
AIP?
Performance of the AIP system has been increased with two Siemens
PEM fuel cells which produce 120kW per module and will give the
submarine an underwater
endurance of two weeks.
