710:. Modifications in Vichy service included fitting the aircraft with larger rudders and two more 7.5 mm machine guns in the rear turret. The extra weapons were added because of the limited capacity of the cannon magazines and the fact that changing them in flight was extremely difficult. Aircraft production had stopped with the German occupation but a 1941 agreement authorized Vichy authorities to have a limited number of military aircraft built and orders were placed for 225 newly built Leo 451s. In order to speed production, considerable use was made of components that had been built in 1940 and stored in the German-occupied zone. The first of the newly produced aircraft flew on 30 April 1942, and by the time the German occupation of Southern France following

LeOs performance and made them difficult to intercept. The diving and climbing speeds were very good as well (the
Italian SM.79 took 17 minutes to reach 5,000 m, compared to 14 for the LeO), even if not that useful for a bomber. LeOs were optimized for medium-altitude operations (5,000 m) but were forced to go far lower to search for and destroy tactical targets, rarely with even a basic fighter escort (H-75, D.520). LeOs were not unarmed and German fighters had to keep a look out for their dorsal turret: on 6 June 1940, gunner sergeant Grandchamp, GB II/11 shot down two Bf 110Cs with the Hispano cannon. German fighters came to avoid this danger by attacking from below, forcing the LeOs to deploy their retractable turret, which slowed them.

In total, the aircraft's armaments comprised: 120 20 mm rounds, 800 7.5 mm rounds, up to seven 200 kg bombs or other combinations (1–2 500 kg bombs in the belly, plus the two 200 kg in the wings). When flown with the maximum payload, this reduced the corresponding fuel load to only 1,000 liters. The fuel tanks were also housed within the wings, these comprising a pair of 880 lts tanks within the inner wings), along with a further two pairs of 330 and 410 liters contained in the external wings.

In addition, several shortcomings was quickly identified with many of these aircraft, including inadequate defensive armaments, being too slow and relatively unmanoeuvrable, and thus too vulnerable for viable sorties over hostile territory. Accordingly, the need for their replacement was apparent. It was out of the

It was at this point that a flurry of additional wartime production orders were issued, calling for hundreds more aircraft to be manufactured, amounting to around 1,549 LeO 45 aircraft of various models. While additional productions lines were established in order to produce more aircraft, much of this extra capacity did not arrive until mere months prior to the catastrophic

In contrast to its predecessors, which had relied on machine guns for self-protection, the emphasis was placed on high-speed high-altitude cruise. The expectation was that high speed would force enemy fighters into tail-chase attacks and to that effect the aircraft was designed with a rear-firing cannon which possessed an unobstructed rear arc of fire thanks to the design of the twin tailfins.

At the same time, the requirements of Plan V were elevated to 1188 B4 bombers, 396 of these being first line aircraft. Accordingly, on 20 February 1939, a tentative order for 100 aircraft was confirmed; on 18 April 1939, a large order for a further 480 LeO 45 bombers was received.

On 21 October 1938, it was specified that all production LeO 45 aircraft were to be equipped with Gnome-Rhône engines in place of the originally envisioned

In May 1937, the Armée de l'Air placed an initial pre-production order for a pair of LeO 450 aircraft, one being fitted with

Various issues with the troublesome

Although the LeOs were typically faster than many fighters and also faster than almost all other types of bomber, the

At the outbreak of World War II, only ten LeO 45s had been formally accepted by the French Air Force. These aircraft were issued to a front line unit to experiment with the new type in the field and flew a few reconnaissance flights over
