12/31/2009. Remarks by Johan Visschedijk: "The Aéronavale had first begun to evince interest in the Bloch 175 in 1940, and an aircraft of this type had been fitted with a torpedo rack and evaluated at Tafaraoui in the summer of 1941.

This interest was maintained, and in 1945 an order was placed on behalf of the Aéronavale for 100 Bloch 175 Ts (Torpillage, Torpedoing). The rear fuselages were to be produced at Bouguenais, the ailerons and tail assemblies at Saint Nazaire, and the outer wing panels at Rochefort, fin al assembly being undertaken at Châteauroux-Déols.

Flown on May 15, 1946, the Bloch 175 T No. I was externally similar to the 1940 version, and No. 31 and subsequent machines had the revised and enlarged tail fins first tested on Bloch 174 No. 53. Deliveries to the Aéronavale began during October 1946 when Flottille 6F began converting to this type from the Ventura.

Armament comprised two wing-mounted 0.787 in (20 mm) Mauser MG 151 cannon and a similar weapon on a SAMM-AB201 dorsal mounting, eight 3.54 in (90 mm) rockets, and one 1,654 lb (750 kg) torpedo on an LBT 130 Alkan rack or three 330 lb (150 kg) Mk.47 depth charges on a SADEA rack. British Mk.XII radar was installed, and during the production run the 1,150 hp Gnome & Rhône 14N 54/55 engines were supplanted by GR l4N 66/67 and 70/71 engines.

Budgetary factors resulted in the initial production order being cut back to 80 aircraft, and production of the Bloch 175 finally terminated in 1950, almost 11 years to the month since the first prototype had flown at Villacoublay."
