The two halves of these nuclear submarines cut in half were Perle and Saphir, respectively. From these two halves, the French experts performed grafting into the complete ship.

The French expert said that the reason they can be joined together by two submarines of the same line, both of the Rubis class and identical design.

The two halves of the submarine were prepared to be grafted by France.

The fact that France had to use two halves of two different submarines to combine because in June 2020, a fierce fire that lasted for 14 hours made the front of the Perle submarine on the dock unusable due to steel structure is deformed, some places do not guarantee the original stability.

But the other half of the 73m-long submarine, which displaced 2,600 tons, was unaffected by the fire. Meanwhile, the French Navy has a Saphir, in the same class, which was decommissioned in 2019 and is waiting to be dismantled.

The front part of the Saphir was assessed to be structurally stable, qualified to be paired with the back of Perle to form a complete attack submarine.

The Perle was then cut in half in February and March. After being placed on a calibrated shelf, the second half of Perle and the front half of the Saphir are now fully welded, the French Navy said.

Paired product is still named Perle but a bit longer. Naval Group said that all pre-construction designs are 3D digital modeling and ensure reliability, safety and does not affect the inherent design of the ship’s combat capabilities.

Perle entered service in 1993, the newest of the six Rubis-class nuclear submarines in the French Navy. During a joint resistance exercise in 2015 between the French and US Navy, a Rubis submarine “sank” the US aircraft carrier USS Theodore Roosevelt.

This exercise took place within 10 days off the coast of Florida, to test the performance and combat capabilities of this aircraft carrier after 4 years of overhaul at a cost of up to 2.6 billion USD.

The French submarine named SNA Saphir S602, belonging to the Rubis nuclear attack submarine class participated in exercises with the US Navy’s Carrier Task Force No. 12, including the USS Theodore Roosevelt ( CVN-71), multiple Ticonderoga-class cruisers and Arleigh Burke class Aegis destroyers and a Los Angeles-class nuclear attack submarine.

Phase 1 of the maneuvers went well when the French navy’s SNA Saphir nuclear submarine was ordered to join the allied US forces in a simulated conflict, in which the states thought The statue attacked the economic and territorial interests of the United States.

By the second phase of the exercise, the submarine SNA Saphir acted as an enemy submarine, with the mission to find and destroy the giant US aircraft carrier.

To do this, Saphir spent days stalking, bypassing the outer barrier under constant threat from P-3C Orion anti-submarine patrol aircraft and P-8A Poseidon of the US Navy, zones Arleigh Burke class destroyers and other anti-submarine defense ships.

The Saphir dodged the detection of anti-submarine forces, broke into the defense systems of the carrier group to avoid detection of long-range anti-submarine equipment and quietly approached the ship. airports worth billions of dollars of the US Navy.

The Saphir was close to the American aircraft carrier USS Theodore Roosevelt and commanded the carrier to lock the target of the carrier in his periscope. The French submarines were then only a few hundred meters from the American aircraft carrier, within the effective range of anti-ship weapons such as torpedoes and Exoxet anti-ship missiles.

Both the US aircraft carrier combat information center held its breath when it discovered the incident and was alarmed when it was attacked by French ships. An attack order was issued, and the Saphir “sunk” theoretically the USS Theodore Roosevelt and most of her escort ships.
