guns could be manned. The ship departed Toulon on 26 October and steamed first to Algiers, French Algeria, where from 29 to 31 October, the 1st Foreign Parachute Regiment and Commando Hubert frogmen unit came aboard the ship. Jean Bart then joined the rest of the intervention force, which included the carriers and , Georges Leygues, the destroyers Surcouf, , , and , and an anti-submarine warfare group. The ships left on 1 November and reached Limassol, Cyprus on the 4th, where the paratroopers and frogmen transferred to amphibious assault ships. On 5 November, Jean Bart steamed south to bombard Port Said, but she fired only four rounds from her main battery before the landing was cancelled. She remained off the city for two more days before departing on the 7th and returning to Toulon by way of Limassol on 13 November. On 1 December, Jean Bart returned to the training squadron. Her last period at sea took place from 11 to 19 July 1957; this was also the last time she fired her main battery. On 1 August, she was reduced to reserve status, despite the reluctance of many in the naval command to see the funds and effort expended in completing the ship be wasted. By this time, a new generation of post-war cruisers and destroyers were beginning to enter service, leading to significant crew shortages. Coupled with the cost of maintaining Jean Bart in service, the need to release the manpower tied up in the ship for more useful vessels led to her withdrawal from active service after just two years. The navy considered a number of modernization proposals to improve the ship's anti-aircraft battery or add guided missiles. The latter concept involved five different variants that ranged from adding missile launchers with 24–44 missiles to the quarterdeck to removing the main battery turrets and reconstructing the forward part of the ship to house a large missile battery with as many as 325 missiles. Alternatively, an air-defense missile armament for testing purposes was considered; this would have involved removing the centerline 152 mm turret and replacing it with a launcher for the American RIM-2 Terrier missile. The 152 mm turret would be retained for re-installation once the evaluation period was over. None of the modernization or conversion projects came to fruition, and the missile batteries that involved removing the 380 mm turrets were not even seriously considered
