Elbit Systems Integrates Active Towed Array Sonar Onboard its Seagull USV

Elbit Systems Ltd. announced today the successful integration of the Towed Reelable Active Passive Sonar (TRAPS) for Unmanned Surface Vessels (TRAPS-USV) onboard the Seagull USV.

The sea trials included multiple deployment and recovery cycles, towing at different speeds and transmission at various power levels.

Integration of the TRAPS-USV sonar enables the Seagull USV to perform Anti-Submarine Warfare (ASW) operations on-the-move, substantially extending its operative range and further enhancing its flexibility. The integration of the TRAPS-USV follows the recent conversion for operation, by the Israeli Navy, of Helicopter Long-Range Active Sonar (HELRAS) dipping sonar onboard the Seagull USV.

TRAPS-USV is the compact and powerful low frequency towed sonar that was recently introduced by Geospectrum Technologies, Elbit Systems’ Canadian wholly-owned subsidiary.

The TRAPS-USV version is a compact variant of the TRAPS, an operationally proven technology that is intended for detection, classification, localization, and tracking of submarines in ASW operations. TRAPS versions are containerized or permanent-fit for any size, diverse purpose vessel. The TRAPS-USV variant is lighter weight but maintains all acoustic active sonar capabilities of the regular TRAPS.

Similar to its “larger brother” TRAPS (with installed or containerized configurations), TRAPS-USV is a Low Frequency (LF) variable-depth sonar intended for detection, classification, localization, and tracking of submarines in ASW operations. TRAPS’ unique advantage is that its’ projector array is reelable and stows on the winch drum with the receive array and tow cable. This unique feature eliminates the need for a dedicated active over-boarding system saving weight, space, complexity, and cost.

The Seagull autonomous multi-mission USV features a plug and play, modular mission payload suites and can perform, in addition to ASW, Mine Countermeasure missions (MCM), Electronic Warfare (EW), Maritime Security (MS), underwater surveys and other missions using the same vessel, mission control system and data links.
