ATLAS Elektronik GmbH at IDEAS 2014 in Karachi

Submarine Technology from ATLAS Elektronik Influences Events in the Maritime Battlespace

ATLAS Elektronik GmbH from Germany participates in the IDEAS 2014 International Defence Exhibition and Seminar in Karachi, Pakistan, by presenting two key products: the ISUS 90 submarine combat management system (CMS) and the SEAHAKE DM2A4 torpedo system, according to Steffen Leuthold, the company’s Head of Communications.
Variants of the ISUS 90 CMS can be found on diesel-electric and fuel cell submarines of 10 different countries, including Chile, Germany, Greece, Italy, Portugal, South Africa, South Korea, and Turkey. According to the company, the fully integrated sensor, C2, and weapon engagement system is scalable depending on the weapons (torpedoes, anti-ship missiles) carried by the submarine. Additionally, to cope with a customer’s individual requirements, variants of the ISUS 90 CMS can consist of four, five or six consoles. As a ‘low cost, low risk’ solution, the ISUS 90 CMS will be in a strong position if selected for other international submarine programmes.

The ‘tried and tested’ ISIS 90 CMS can easily be adapted to suit individual customer requirements and diverse operational scenarios.

The SEAHAKE is a dual-purpose, fibre-optic wire-guided heavyweight torpedo (HWT), featuring a modular battery system and an electric propulsion motor with very low self-noise. The HWT has been sold to a number of countries, including Argentina, Chile, Colombia, Ecuador, Germany, Greece, India, Indonesia, Israel, Norway, Peru, South Africa, South Korea, Spain, Turkey, and Venezuela. The latest success includes deliveries for the Pakistan Navy’s AGOSTA 90B and Spain’s “Isaac Peral” class (S-80A) submarines. ATLAS Elektronik developed a 300µm wire for the torpedo weapon selected by the German, Pakistan, and Spanish Navies.
The SEAHAKE HWT features eight sections containing the homing head with conformal transducer-array and wide panorama angle; the electrolyte-activated, fully-capsulated battery section with up to four primary batteries with cooling system; the warhead with large explosive charge and impact and proximity fuses outfitted with safety and arming devices; the electric high-frequency permanent magnet motor with very low self-noise and planetary gear box; asymmetric skew propellers with a nine blade front and a seven blade rear propeller; the electronics section with wake sensor and central computer for all torpedo functions; the guidance section with fibre-optic guidance wire; and the rear section. The HWT offers fully digitised, jam-resistant signal processing. ATLAS Elektronik also markets the SEAHAKE Mod 4 ER torpedo. It is designed for network centric warfare, littoral warfare, and coastal defence. Its maximum combat range is quoted at 140km (76nm). The torpedo can be launched from surface ships and attack submarines.

Above: The SEAHAKE Mod 4 ER long-range torpedo was first test-fired in March 2012 in the Eckernförde Bay with cooperation of the German Armed Forces’ Technical Centre for Ships and Naval Weapons (WTD 71); in the background is the SEAHAKE DM2A4 HWT.
Below: The high-frequency permanent-magnet AC motor of the SEAHAKE DM2A4 HWT provides a 50% increase in maximum speed and a 400% increase in energy content compared with the DM2A3 while the weapon is 50% quieter.
