The new SEAMOSC module was developed by Lacroix to counter threats guided in the visible range or by Laser. To do so, the launcher deploys a smoke screen specifically designed for the naval environment:
- Attenuation in visible band > 45 dB
- Backscattering of the beam at usual Laser frequencies
- Grey smoke screen
MOSC stands for “Masking Optronic Screening”. The concept retained for the SEAMOSC launcher is in line with the existing SYLENA launchers:
- Modular launcher: to choose the right number of modules needed and their distribution on the deck, depending on:
- Ship’s geometry,
- ship’s specific needs (directive masking for amphibious operations for example),
- cloud renewal requirements,
- Fixed laucher: for maximum reliability and uptime with very low maintenance
- Quick, easy and safe reloading,
SEAMOSC is available in two configurations depending on customer requirements: 6 ammunitions or 9 ammunitions. Each launcher can be easily reloaded by the crew, even when the vessel is underway at sea.
The new SEAMOSC launcher comes ten years after the launch of the first SYLENA DLS. It is also the fourth launcher in the family, highlight Lacroix’s innovation capabilities. The SYLENA DLS range now consists of:
- The SYLENA LW
- The SYLENA Mk1
- The SYLENA Mk2
- The SYLENA SEAMOSC
Lacroix is also working on the future of naval electronic warfare: Active Off-Board Decoys (OBAD).
Following a call for projects from the Agence Innovation Defense (the French DARPA), for which a LACROIX proposal was selected, the company continues to work on a technology for the implementation of OBAD (jammer embedded on a UAV), a solution which is one of the candidate systems for future FDI self-protection.
This project, named VESTA (Véhicule Ejecté Support Tactique d’Autoprotection), unveiled by LACROIX during Euronaval 2020, has been conducted in a collaborative approach that integrates state actors (AID, DGA, French Navy…), and several civilian or defense companies of the European Defence Technological and Industrial Base.
Lacroix’s Naval Electronic Warfare briefing
During the Euronaval 2022 press tour, Xavier Cadour, Naval Key Account Manager at Lacroix, gave us a briefing on naval electronic warfare.
Mr. Cadour introduced the soft kill solutions being offered by Lacroix, including the Corner Reflector (CNR) technology.
The EW expert also discussed:
- the SYLENA family of decoy launchers
- the new SEAMOSC masking and screening solution
- the future VESTA off board active decoy (OBAD)
