The French Navy’s future lead Jacques Chevallier-class logistic support ship (LSS) has successfully completed the initial sea trial series.

The Organisation for Joint Armament Cooperation (Organisation Conjointe de Coopération en matière d’ARmement – OCCAR) announced the development on 31 January.

The trials were held between 25 and 28 January 2023 and primarily focused on verifying the ship’s navigation system.

It was conducted a month after the vessel officially registered its first nautical miles at the sea on 20 December last year.

The four-day-long effort aimed to assess and validate the performance and capabilities of various systems equipped aboard LSS Jacques Chevallier.

The latest test further marks a significant milestone and has laid the foundation for the upcoming qualification and acceptance trials, which are expected to take place later his year.

Being developed by a temporary consortium between Chantiers de l’Atlantique and Naval Group, the future support ship has been named after a 20th-century French Naval Engineer, Jacques Chevallier.

The keel for the first vessel of its class was laid in February 2021 at Fincantieri’s naval shipyard in Naples, Italy.

The new ship is being constructed under the FLOTLOG programme (Flotte Logistique), led by OCCAR on behalf of the French Defence Procurement Agency (DGA) and the Italian Directorate of Naval Armaments (NAVARM).

FLOTLOG is being executed as part of the French-Italian cooperation.

The Jacques Chevallier-class replenishment vessels will be deployed to perform two major tasks, including military operations and civilian rescue operations.

The multi-mission ships can further be used for replenishing aviation fuel, food, water, ammunition, and spare parts for the other naval vessels operating at sea.
