Publicado: 13/05/2025

SAES and Thales ratified the agreement today for the integration of the ‘Sonoflash’ sonobuoy into SAES’s Sonobuoy Acoustic Processing System (SPAS) at the International Defence and Security Expo (Feindef), held in Madrid from 12th to 14th May. This partnership, initiated in 2021, has now come to fruition, enhancing the SPAS’s competitiveness in Anti-Submarine Warfare (ASW) and Maritime Surveillance fields.

In a landmark achievement reinforcing the technological collaboration between SAES and Thales DMS, the integration of the ‘Sonoflash’ sonobuoy into the sophisticated SPAS system crafted by SAES has been successfully completed. This initiative, agreed upon at the International Defence and Security Exposition (Feindef) in 2021, has now been realised, bringing innovation to the ASW capabilities of platforms such as the Airbus C295 aircrafts.

A sonobuoy is an advanced acoustic sensor designed for deployment from Anti-Submarine Warfare (ASW) platforms like Maritime Patrol Aircraft (MPA) or helicopters to detect, identify, locate, and track submarines. Sonobuoys transmit the captured acoustic signals from the underwater environment to the ASW platform via VHF frequencies. They play a crucial role in detecting underwater threats, enabling naval forces to monitor the position and movement of potential underwater threats.

The Sonoflash by Thales represents a significant leap in this technology, combining high-speed communication with exceptional acoustic performance. It is interoperable with advanced sonar systems, enhancing ASW operations through more accurate data processing

SAES’s SPAS is an acoustic processing system designed to handle up to 64 passive and active sonobuoys, both analogue and digital. The SPAS provides multi-static processing capabilities, enhancing the detection of underwater threats and significantly improving its efficiency and coverage. The integration of ‘Sonoflash’, noted for its interoperability and communication performance, further boosts these capabilities.

Javier Mármol Peñalver, President of SAES, remarked: “The integration of Sonoflash into our SPAS system is a crucial step in solidifying our position in the international market, not only maintaining our standards of innovation and reliability but also elevating them.”

Jesús Sánchez Bargos, president of Thales Spain, stated that “this agreement represents an excellent example of successful industrial cooperation between Thales and SAES that ensures timely innovation without losing agility, while elevating SAES’ position in the market with an interoperable system that guarantees strategic autonomy.”

The installation of the SPAS in Airbus C295 aircraft, as well as in helicopters and surface vessels, underscores its adaptability to various platforms, offering unmatched added value in Anti-Submarine Warfare operations. With this integration, SAES and Thales deepen their collaborative relationship and enhance the security and efficiency of Armed Forces, positioning the SPAS at the forefront of submarine technology.

Participación en consorcios de ámbito nacional e internacional_

SAES has participated in the development of the MIRICLE project (December 2021 to December 2023), selected for funding by the European Commission in the 2020 EDIDP (European Defence Industrial Development Program) call, under the theme: Solutions to detect, identify, counter, and protect against the threat of mines, including those operating at great depths.
