3.7 cm Flak M42
[ edit ]
The 3.7 cm Flak M42 was a longer caliber version of the Wehrmacht 's 3.7 cm Flak 36, 69 caliber as opposed to 57 caliber. It replaced the older 3.7 cm SK C/30 that had been designed in 1930. The gun was loaded with a five-round ammunition clip, giving it a rate of fire of 250 rounds per minute, unlike the SK C/30 which was single-shot with a rate of 30 rounds per minute. The M42 was also about 134 kg (295 lb ) lighter than the SK C/30 and had gun shields.
LM 42U Mount
[ edit ]
The LM 42U mount was developed specifically for the 3.7 cm Flak M42U. It was manned by a 3-man crew, with a fourth man operating as the loader.[4]
DLM 42U Mount
[ edit ]
The twin mount was based on the LM 42U design, in which the 3.7 cm Flak M42U guns were mounted side by side.[5]
LM 43U Mount
[ edit ]
The LM 43U mount was the final design of mount used on U-boats. It was a further improvement on the LM 42U. The LM 43U was only known to be installed on these U-boats (U-249 U-826 U-977 U-1023 U-1171 U-1305 U-1306 [5]
