Making the sea safer [CANSEC17D1]

31 May 2017

Having signed a memorandum of understanding with Magellan Aerospace for collaboration on the SeaSpider Anti-Torpedo Torpedo (ATT) at CANSEC 2016, Atlas Elektronik (Booth 505) will use this year’s show to focus on this torpedo, which will employ Canadian rocket and propellant technology.

SeaSpider is the world’s first ATT, designed to provide an effective and affordable solution to counter threats to ships, submarines and sailors against torpedo attack, in both deep and shallow water, even in the worst ‘sonar weather’. SeaSpider actively targets the incoming threat torpedo independent of its type of homing functionality, with the aim of destroying or disabling it with explosive and/or kinetic energy, before it completes its mission.

Torpedo propulsion has seen great advances in recent years both in range and speed. The modern torpedoes are impervious to ‘soft-kill’ torpedo defence technology and represent the most dangerous threat to shipping today. SeaSpider’s ‘hard-kill’ ATT is said to provide defence against any and all threat torpedo types in all relevant environments.

SeaSpider is specifically designed to be affordable for navies in procurement and operation. To achieve a low unit cost, uniquely for guided underwater weapons, a solid propellant rocket motor was chosen as propulsion element, which provides affordable and compact high-energy performance. Other design choices aim to minimise production cost.

The operational concept allows for a ‘torpedo alarm’ configuration with a very low false alarm rate, which further reduces expenditure.

The maintenance-free canistered round reduces maintenance effort and simplifies handling.
