It was my error, I should have checked. I mixed it up with air force. See how i can concede, when I make an error?

Which seems to come naturally to you suggesting you make a lot of errors , pops.
#Acoustic buoys
The DGA Naval Techniques centre of expertise has conducted with thalesgroup tests to evaluate the emission performance of future air-droppable acoustic buoys Sonoflash, an air-droppable acoustic buoy designed to meet anti-submarine warfare requirements by 2025, in particular to secure the deployment of ships and SSBNs.

This Sunday, March 26, 2023, the 2nd nuclear attack submarine of the Barracuda series, the Duguay-Trouin, made its first trip to sea in Cherbourg (Manche).
On Sunday 26 March 2023, the second nuclear attack submarine of the Barracuda series, the Duguay-Trouin, made its first trip to the large harbour of Cherbourg (Manche). She was accompanied by the tugs Saire and Fréhel as well as two pushers. The previous evening, she had left the shelter of the naval base to spend the night at the Homet dyke.
No comment was made on this trip, neither by the Directorate General for Armaments, nor by the French Navy or Naval Group.
An important step
This first sortie, initially mentioned in December, has been postponed several times. The only indication, in Cherbourg, was the order of the Maritime Prefect for the Channel and the North Sea, issued on 1 March, regulating navigation in the harbour between 18 March and 1 May, during the submarine's movements.
In any case, this first outing marks an important stage, announcing the imminent start of the sea trials. The first of these will be the static dive, which will enable the submarine to be 'weighed'. For the Suffren, the first of the series, this took place two days after it left the dock, in the spring of 2020.
This static dive is the first of the sea acceptance tests. They will continue in the Channel, then in the Atlantic. The aim is to test and validate the platform, its propulsion, the manoeuvrability and the behaviour of the submarine underwater.
These initial tests are being carried out by the blue crew, who have been following the completion of the Duguay-Trouin in Cherbourg for over two years.
In the summer, the red crew will take the controls in Toulon (Var) to test the operational and military qualities of the submarine, which will lead to its admission to active service.
Before that, Naval Group plans to deliver the submarine to the French Navy before the end of the year. /DeepL
--------------------
1st "Static dive"
"Static weighing": the weight of a submarine when it is new or coming out of a major refit (IPER) is based solely on calculation. It is therefore theoretically "light" and during this dive it is adjusted in weight and trim so that it is perfectly weighed.
The boat is positioned in a safe area of water, for its own safety and that of others. The crew conducts a watertight round. The captain can then order the drains to be operated and the ballast tanks to be filled. The skippers again report on the state of watertightness.
The level of all capacities (trim tanks, adjustment tanks) and the position of each sailor, equipment and mobile weights on board are then carefully recorded to obtain a "reference situation" which will be used before each departure to calculate the day's weight.
If the static dive should show too great a difference between theory and practice, then the ballast is modified, consisting of sows distributed throughout the boat, which should never be touched. /deepl

The DGA has taken delivery in Brest of the UAV implementation simulator: "Maritime mines counter-measures" (MMCM) of the "Future naval mine countermeasures system" (SLAM_F) for the @MarineNationale
The SLAM_F: Système de lutte antimines navales futur (Future Naval Mine Countermeasures System) is intended to renew the entire French mine warfare capability.
The MMCM Maritime mines counter-measures, is the result of a Fr-Uk cooperation
An MMCM system is composed of 2 surface drones to identify and neutralise mines:
one equipped with a towed sonar
one equipped with a remotely operated robot
and 2 underwater drones to :
detect, classify and locate mines.

On 19/04, the SSBN Le Terrible launched an M51 strategic ballistic missile. The 6th M51 launch from a SSBN, this test was carried out without a nuclear warhead and in strict compliance with France's international commitments
If it is indeed the FREMM Bretagne that is engaged in Formidable Shield 23, then the illustrator is mistaken: D651 is the NormandieExercise Formidable Shield coming soon!

In order to make them "anonymous", soon hull numbers and name (at the stern) will be removed from the French Navy vessels. This has already started:
The nuclear submarine "Perle" returns to sea, three years after a fire on board
According to the Ministry of the Armed Forces, the "Perle" will return to operational service "at the end of its sea trials period after verification of its ability to navigate safely and validation of its combat systems".
The nuclear attack submarine Perle, which was ravaged by fire in 2020, is to return to sea. The vessel has "carried out propulsion and manoeuvrability tests on the surface", following the maintenance work that followed its repair, the Ministry of Defence announced on Tuesday 23 May. It "passed a major milestone by carrying out its static dive on 22 May", the ministry said, specifying that the aim of these tests was "to ensure the submarine's ability to navigate safely".
The submersible, which entered service in 1993, was hit by a violent fire in July 2020 during a period of unavailability for maintenance and repairs (IPER). The fire, probably caused by a light that burned a sheet of vinyl plastic, caused considerable damage to the front of the submarine, which was stripped of its weapons, electronics and nuclear reactor.
The decision to refurbish the submarine led to an extensive ten-month refit. The submarine was transported to Cherbourg (Manche) on a ship. The rear of the Perle was welded to the front of another submarine of the same class, the Saphir, which will be decommissioned in 2019. This €110 million Lego had lengthened its size by one metre and added 68 tonnes to its total diving weight of 2,700 tonnes.
An important part of the Navy's strategy
The Perle then returned to Toulon on the same ship to resume the maintenance work interrupted by the fire. The IPER project, which is carried out every ten years, consists of restoring the potential of the ship's nuclear propulsion by recharging it with uranium, checking its installations, its armament consisting of torpedoes and anti-ship missiles, its combat system and its propulsion.
According to the Ministry of Defence, the Perle will return to operational service "at the end of its sea trials period after verification of its ability to navigate safely and validation of its combat systems". Its return to service is an important element of the navy's strategy, which is based on the presence of six nuclear attack submarines, one of whose missions is to support nuclear-powered ballistic missile submarines and also to escort the Charles-de-Gaulle aircraft carrier, a key element of France's deterrent. /deepl
