What was ordered to replace the French heavy tank the Char2c during the late Interbellum? by the
FCM F1 The FCM F1 was a French super-heavy tank developed during the late Interbellum by the "Forges et Chantiers de la Méditerranée" company. Twelve were ordered in 1940 to replace the Char 2C, but France was defeated before construction could begin, a wooden mock-up being all that was finished. The FCM F1 was large and elongated, and had two turrets: one in front and one in the back, with a single high-velocity gun in each turret. The rear turret was higher so it could shoot over the first one. The vehicle was intended to be heavily armoured. Its size and protection level made it by 1940, at about 140 tons the heaviest tank ever to have actually been ordered for production. Despite two engines its speed would have been low. The primary purpose of the tank was to breach German fortification lines, not to fight enemy tanks. The development path of the FCM F1 was extremely complex, due to the existence of a number of parallel super-heavy tank projects with overlapping design goals, the specifications of which were regularly changed. For each project in turn several companies submitted one or more competing proposals.
Type 41 class patrol boat The "Type 41" Class was a type of patrol boats of the Military of Switzerland, commissioned during the Second World War to patrol the border lakes of Switzerland. The class comprised nine units, commissioned between 1941 and 1944 in three series: "Thun" and "Brienz" in December 1941, "Sargans", "Schwyz" and "Unterwalden" in July 1943, and "Spiez", "Bönigen" and "Brunnen" in April 1944; Furthermore, the prototype "Uri" was also commissioned. They remained in service until late 1983, when they were replaced by the more modern Type 80 ("Aquarius" class). In 1962, the units of the class were upgraded with an electric generator, radars and radios, and had their armament upgraded: the Type 41 anti-tank rifle at the bow was replaced by a 20mm autocannon, and the twin anti-air MG 38 machine guns at the stern were replaced by an MG 51 machine gun.
