1943 Type was a further simplified and slightly enlarged version of the M 1940.
These ships were designed for block construction which had originally been suggested
by AG Neptun
and each block, weighing up to three to five tons and the assembly work was to
have been distributed amongst eleven shipyards.
However, the block system
suggested by AG Neptun
was dropped in favour of Dr Rodin of F.
, Königsberg prefabricated system due to the logistics involved
a further nine months of design work was needed to perfect the prefabricated sections.
Planned production was for three to four weeks for the construction of a
section, and up to one week for assembly and launch, two weeks were fitting out,
and one week for trials. However, due to delays caused by the deteriorating war
conditions, delays of up to six months or more were not unusual.
prefabricated sections were as follows
section 1 Aftership.
section 2 Crew accommodation.
section 3 Engine room.
4 Boiler room.
section 5 Foreship.
section 6 Deck, Bridge.
section 7 Upper deck and superstructure.

ships were built by the following shipyards. AG
