5” Vehicle for Underwater Applications & Black Arrow, the New Generation Lightweight Torpedo

    Head of Underwater System Engineering

5” vehicle for underwater applications:

Based on the experience of the former company WASS, Leonardo Defence System Business Unit has developed a 5” vehicle for underwater applications. The initial application has been the Mobile Target Emulator (MTE) in service with several Navies for the self defence of Surface and Submarine platforms. The upgrade of this vehicle has been carried out with the modern techniques of System Engineering. The result is to have a common vehicle capable to host different payloads and in particular a new acoustic system to generate a Mobile Target Jammer Emulator (MJTE) and an Acoustic Head and a Warhead to create a mini torpedo (Black Sorpion). The aim of the MJTE is to reduce the number of effectors for each reaction against an attacking torpedo, while the aim of LCW is to support the process of contact classification on low confidence contacts, without employing LWT (Lightweight Torpedoes), also if more performing but more expansive,.

This paper explores and presents state of the art of LDS on these solutions.

Black Arrow, the new generation Lightweight torpedo

Based upon unique experience developed through partnership with over 70 nations, Leonardo Defence System Business Unit (Based on the experience of the former company WASS) intends to underline its market leadership as a global provider of technological excellence and solutions for the underwater domain in which Leonardo proposes, in the field of Lightweight torpedoes, the most advanced new generation Lightweight torpedo named “Balck Arrow”. Balck Arrow can be launched from Surface or Airborne platforms, best in class against nuclear powered, conventional and “midget” underwater threats with incredibly high performance both in shallow and blue waters, in addition to the most advanced performance against all the underwater threats allows, using its Li-Po rechargeable battery, to increase the training capability of the end user with an enormous reduction of training costs.

Vertical Launch Antisubmarine Rocket (ASROC) (VLA)

  • Mr. Adam Bergeron
    Program Manager

Some allied navies have either invested or are interested in investing in significant improvements to their Anti-Submarine Warfare (ASW) capability. ASW is a growing threat and increasingly dangerous to United States international partners from near-pear adversaries. Multiple allied navies have also wisely invested in the Lockheed Martin Mk-41 Vertical Launch System (VLS) which can not only deploy multiple anti-air, anti-ship, and strike missiles, but also the Vertical Launch Antisubmarine Rocket (ASROC) (VLA). VLA is a rocket propelled, three-stage weapon capable of carrying a lightweight torpedo payload to ranges upwards of 16,500 meters – well outside the submarines attack range. VLA eliminates the surface ship ASW capability gap, and restores the advantage to the surface ship. Lockheed Martin has over 26 years of proven VLA performance with over 1,200 VLA produced inside integrated combat systems for the U.S. Navy and Japan Maritime Self-Defense Force. VLA equipping enables allied and partner navies to either neutralize the enemy submarine threat or provide a defensive stand-off posture for the surface ship which forces the submarine reconsider their planned attack. This presentation will describe the components and “total solution” 360-degree standoff engagement capability during all-weather operations that VLA provides in both littoral and open ocean environments.

The Path to Achieving a Truly Autonomous In-Stride Mine Clearance Capability, and Maximizing ASW Capability for Small Surface Combatants through Variable Depth Sonars

    Seapower Business Development Executive

For in stride mine clearance:

Seaborne mines continue to pose an ominous threat to naval and maritime forces worldwide. Mines are used to attack ships 200 times more than any other weapon. Adversaries that rely upon defensive and offensive mining leverage the natural challenges associated with littoral, surface and deep undersea environments. Extremely capable low-cost sea mines, when placed in the challenging undersea environment, currently require costly and time intensive countermeasure solutions. These MCM solutions involve a myriad of systems that only do a portion of the find-fix-finish process, each one step at a time to achieve mine disposal. To shorten the clearance timeline and to do all of this in stride, you need: a sharper sonar picture; a smarter sonar; and an autonomous neutralizer. As shown in recent demonstrations with the US Navy, Raytheon, with its AN/AQS-20C mine hunting sonar and revolutionary Barracuda mine neutralizer, is making great strides toward making in-stride mine clearance a reality.

For VDS:
As the last hundred years of naval history has shown, small surface combatants, such as frigates and corvettes, are ideal platforms for ASW. As autonomous surface vehicles grow in size and capability, they too will have a role in surface ASW. However, the small size of these vessels can limit the available space for towed array and VDS systems. These systems, which are much more effective than bow or hull mounted sonars, and particularly suited for a wide variety of water conditions, are critical systems for optimum surface ASW performance. Raytheon continues to advance the technology for compact, modular VDS systems with its DART-X and SQS-62 VDS systems, currently undergoing developmental and operational testing with the US Navy on its Littoral Combat Ship.
