Bridge structure and armament.

#1

Hello to all :D; a query: Changes in bridge structure and the armament - The case of U 453.

According to the survivors of the U 453 it is specified that in the patrols 7th and 8th she had a new configuration namely, deck gun of 88 and the "Mittelmeerturm" that was turm 0 but elongated to carry two Breda twin machine guns of 13.2 mm (one pair to each band) and to the rear the machine gun of 20 mm C / 30. The Breda machine guns were retractable and were stowed in airtight containers located in the bands of the platform.

As far as I know these platforms were placed in La Spezia from the summer of 1942 to the submersibles that operated in the Mediterranean. According to the history of the submersible I think that this modification was carried out at the end of the 6th patrol when the U 453 moored in La Spezia on October 15, 1942, but I am risking, does anyone have an exact date?

on the bridge is also appreciated

U 453 (Type VII C) returning to the port of Pola (as per the source); The sail with two twin 20 cm cannons on platform I and a Flak vierling (quadruple 20 cm cannon) on platform II (wintergarten) is interesting. See the particular camouflage scheme............................

Hello to all :D; more:................................

U-Flak.

The U-flaks were 4 VIIC submersibles (U 441, U 256, U 621 and U 953) that were modified to act as surface escorts for incoming and outgoing attack submarines operating from French Atlantic bases. They had considerably increased anti-aircraft firepower and were intended as traps for aircraft.

3 more submarines were set aside as additional U-flak (U 211, U 263 and U 271), but none of them were completed for that purpose, although conversion certainly began on all of them. They eventually returned to service as traditional VII C attack boats.

Can someone give me details about the compartments located under the AA platform? Cheers. Raúl M 8-).
