Displacement, tons: 1,450 surfaced; 1,830 dived
Dimensions, feet (metres): 183.4 × 23 × 19.7
(55.9 × 7 × 6)
Main machinery: Diesel-electric; 1 MTU 16V 396 diesel; 4,243 hp(m) (3.12 MW); 1 alternator; 1 Siemens Permasyn motor; 3,875 hp(m) (2.85 MW); 1 shaft; 9 Siemens/HDW PEM fuel cell (AIP) modules; 306 kW; sodium sulphide high-energy batteries
Speed, knots: 20 dived; 12 surfaced
Range, miles: 8,000 at 8 kt surfaced
Complement: 27 (8 officers)
Torpedoes: 6-21 in (533 mm) bow tubes; water ram discharge; STN (formerly AEG) DM 2A4. Total 12 weapons.
Countermeasures: Decoys: TAU 2000 (C 303) torpedo countermeasures.
ESM: DASA FL 1800U; radar warning.
Weapons control: Kongsberg MSI-90U weapons control system.
Radars: Navigation: Kelvin Hughes 1007; I-band.
Sonars: STN Atlas Elektronik DBQS-40; passive ranging and intercept; FAS-3 flank and passive towed array.
STN Atlas Elektronik MOA 3070 or Allied Signal ELAK; mine detection; active; high frequency.
Programmes: Design phase first completed in 1992 by ARGE 212 (HDW/TNSW) in conjunction with IKL. Authorisation for the first four of the class was given on 6 July 1994, but the first steel cut was delayed to 1 July 1998 because of modifications needed to achieve commonality with the Italian Navy, which is building two identical hulls. Changes included greater diving depth and improved habitability. HDW Kiel, and TNSW Emden, are sharing the work with the forward half being built by HDW and the back end by TNSW with final assembly alternating between the shipyards.
Structure: Equipped with a hybrid fuel cell/battery propulsion based on the Siemens PEM fuel cell technology. The submarine is designed with a partial double hull which has a larger diameter forward. This is joined to the after end by a short conical section which houses the fuel cell plant. Two LOX tanks and hydrogen stored in metal cylinders are carried around the circumference of the smaller hull section. Zeiss search and attack periscopes.
Operational: Maximum speed on AIP is 8 kt without use of main battery. All to be based at Eckenförde as part of the First Submarine Squadron.
Sales: Two identical submarines are being built in Italy and four for Greece.
Opinion: First of class trials are to start in October 2002 and will continue until she commissions. This should allow enough time to prove the new AIP system although reliability tests were undertaken in a Type 205 submarine in 1988/89.

PERMASYN®
Type
Synchronous electric motor with permanent magnet field excitation.
Description
Siemens has developed the PERMASYN® permanent magnet field excited static inverter-controlled synchronous propulsion motor for the new generation submarines. The motor incorporates a bell-shaped rotor with permanent magnets and a polyphase stator winding with winding phases separately supplied by inverters. These inverters are fed by a DC power supply. The inverters are mounted inside the rotor (non-rotating). By means of pulse-controlled insultaed gate bipolar transistors (IGBTs), the inverters supply the stator windings with rotor position dependent AC. In this way the motor handles changing speeds in both forward and reverse directions with ease and offers step less speed variation over the whole forward and astern range.
Each inverter has its own open-loop and closed-loop control, which was specially developed for PERMASYN® drives. The control devices generate special pulse patterns to achieve minimum noise levels, minimum EMI and best efficiency.
All electronics for control and monitoring are mounted inside the motor housing.
The bell-shaped rotor has a magnetic yoke with high-energy capacity permanent magnets mounted on the outer circumference. With only low losses from the rotor, complex noisy air cooling apparatus is not required.
The stator consists of a solid, closed-yoke ring and is multiphase wound, each phase being electrically separated. The stator and the electronics are cooled via cooling water ducts and cooling plates.
The main advantage of the PERMASYN® motor compared with a conventional DC commutator motor developing the same torque, is that the motor as well as the entire propulsion system is much smaller. As such it will fit more suitably in a submarine design through better use of the available space. The design allows lower nominal speed and thus the use of propellers with better efficiency, which results in an overall lower noise emission.
Operational status
On order for the Type 212 boats of the German and Italian navies (four and two boats respectively) and for the Type 214 submarines of the Greek (four) and South Korean navies (three).
Contractor

Howaldtswerke-Deutsche Werft (HDW) of Kiel and Thyssen Nordseewerke (TNSW) of Emden lead the world in the design and build of non-nuclear submarines using fuel-cell air-independent propulsion. They are building four Type 212A (U 212A) submarines for the German Navy; Italy will receive two. Greece has ordered four of the larger Type 214s (U 214s), while South Korea has ordered three of these.
