| Source measurement | The homing head's conformal transducer array permits detection angles of +/-100° in the horizontal and +/-24° in the vertical, therefore supporting larger acquisition angles in comparison to traditional flat arrays.[source]DM2A4 · Description; only the objects and conditions stated in this passage The weapon has a modular design that includes 2–4 silver-zinc oxide battery modules and is able to achieve a range of more than 50 km (27 nmi ) and a speed exceeding 92.6 km/h (50 kn ) powered by a high frequency permanent magnet motor, with a closed-loop cooling system independent from the environment. Exact performance data are classified. The torpedo design template may also be used as the basis for ROV . The weapon is armed with a 260 kg PBX ( RDX – aluminium ) warhead (equivalent to 460 kg of TNT ) with magnetic influence and contact fuzes . The charge and fuse are insensitive and electromagnetic pulse safe.[source]DM2A4 · Description; only the objects and conditions stated in this passage The weapon has a length of 6.6 m when configured with 4 battery modules, and is respectively shorter when configured with either 3 or 2 battery modules depending upon the requirement of the operating unit. Diameter of the unit is 533 mm.[source]DM2A4 · Description; only the objects and conditions stated in this passage In May 2018, Hellenic Navy released a Request For Information letter (RFI), asking various companies for acquiring 533 mm heavy torpedoes for its four Type 214 Papanikolis submarines plus one updated Type 209 AIP Okeanos . In October 2020, DM2A4 was chosen as the preferred solution, with a program consisting of 36 DM2A4, plus refurbishment of a number of older SUT Mod0 to Mod4 standard, plus extra batteries for older SST torpedoes / SUT Mod0 torpedoes, with a total cost of 105 mln euro. In September 2021, the contract was modified, with a program consisting of 44 DM2A4, without refurbishment of a number of older SUT Mod0 to Mod4 standard, plus extra batteries for older SST torpedoes / SUT Mod0 torpedoes, with a total cost of 110 mln euro. Deliveries of the new torpedoes started in 2025.[source]DM2A4 · Service history; only the objects and conditions stated in this passage | — |
