have hydrogen storage onboard. The hydrogen would be replaced by bioethanol and oxygen tanks. Bioethanol, along with the reformer manufactured by Hynergreen will both be used to create hydrogen. The oxygen and hydrogen will then be transferred to the UTC Aerospacefuel cell. The chemical reaction occurring in that cell will have two prod- ucts: electricity and water. The latter would be extracted outside the vessel, along with CO2 coming from the reformer. Before it gets out, the water would be cooled down and mixed with the seawater. The electric- ity would then be sent, via a voltage converter, to the 3,500 kW electric AC motor. The motor will be used directly to propel the submarine, but it will also be used to covertly charge the batteries (covertly - without a necessity to go to the surface). The system is to provide the subma- rines with an ability to stay underwater for 3 weeks, without a neces- sity to go to the periscope depth or to charge the batteries. The AIP system is going to be complemented by two batteries (probably the latest generation Li-Ion batteries, but it is uncertain whether the first vessel would get these) and three diesel engines with a total power output of 3,600 kW. Lockheed Martin - Edo is responsible for the combat system of the sub- marines. The system is to include: bow, cylindrical passive sonar, side passive sonars, active short-range sonars, passive rangefinder, and mine-countermeasure sonar. SAES and QinetiQ are to deliver the DTAS towed sonar array. The electronic hardware would include the Indra Ar- ies-S LPI (Low Probability of Intercept) radar, IFF system, and the Indra Pegaso SIGINT/ELINT solution. The vessels would also be fitted with Kollmorgen Electro-Optical and Calzoni electro-optical periscopes that will not penetrate the hull. The communications suite is to include ICCS radio system, EID UB-80 satcom link, and Tecnobit Link-22 datalink. Six 533 mm torpedo tubes (active, hydraulic) are to be arranged at the NAVY
