May, Béarn used her CAMS 37 seaplanes to conduct trials evaluating the visibility of the submerged submarine on 4–16 May. The ship participated in exercises in the Western Mediterranean and off the coast of Morocco from 27 May to 10 July. A few months later the carrier cruised down the Atlantic coast of Morocco, flying a few reconnaissance missions in southern Morocco in late October to intimidate any rebellious Berber tribesmen and visiting Dakar, French West Africa, Madeira and the Canary Islands. During this voyage a single Wibault 74 fighter was tested. During Béarns refit from December 1929 to April 1930, the downward angle of the stern was changed to match the 4.5 degrees of the bow. On 8 May the carrier had aboard 10 D.1s, 5 LB.2s, 16 PL.4s and 3 CAMS 37s. Two days later she participated in the naval review of the by Doumergue in Algiers that commemorated the centenary of the French conquest of Algeria. Upon her return to Toulon on 14 June, the LB.2s were replaced by D.1s, pending delivery of the Wibault 74s on order. At the end of December 7B1 began practicing simulated torpedo drops. The Levasseur PL.7 torpedo bomber had been delivered to 7B1 when Béarn accompanied the on its North African cruise from 8 May to 24 June. She was refitted at the end of the year. The Levasseur PL.10 had replaced the PL.4 in 7S1 by April 1932. On the third of that month, the ship was visited by François Piétri, Minister of National Defense. At this time 7C1 was having its new Wibault 74s modified and could not participate in the squadron's Eastern Mediterranean cruise from 15 April to 25 June. They made their first deck landings on 20 July. The ship was transferred to the (2nd Battleship Squadron) in October. The following month an inspection criticized the carrier's combat readiness as she was limited to a speed of . In 1933 the strength of each squadron was increased from six aircraft to nine, except for the fighter squadron which increased to ten. During the 1st Squadron's cruise to North Africa from 3 May to 24 June, Béarns squadrons practiced searching for and attacking enemy ships from a land base in mid-May and used Oran, French Algeria, for target practice a few days later. A few months later, 7B1's PL.10s practiced attacking battleships escorted by destroyers on 20 July.
