Ständige Regelbauten     Vf Bunkers


On our page on the history of the Atlantikwall you have been able to read how the Germans gradually increased the strength of their bunkers, from feldmäβig (field-like)(walls between 30cm and 1m thick) over verstärkt feldmäβig (semi-permanent)(abbreviated as Vf)(walls between 1 and 2 metres thick) to ständig (permanent)(walls between 2 and 3.5 metres thick)

Actually, the thickness (and thus strength) of the walls and ceiling of the permanent and semi-permanent bunkers was indicated by means of a letter from the alphabet, resulting in the following system:

Letter Thickness
bunker code Protection
A 3.5m - 65cm St(ändig) Schusssicher
A1 2.5m 25-35cm 42cm St(ändig) Schusssicher
B 2 20cm 25-30cm St(ändig) Schusssicher
B1 neu 1.5m 10cm 12cm L(eicht) Splittersicher
Verstärkt feldmässig
B 2m 20cm 25-30cm L(eicht) Schusssicher
B1 alt 1m 10cm 12cm L(eicht) Splittersicher
C 60-80cm 6cm - - Splittersicher
D 30-50cm 2-4cm 2.5cm - Splittersicher


As indicated in the table above, the letter (combination) L or St was painted at the entrance of bunkers. Knowing which of these types a bunker was was important in the event of troops having to shelter against an air attack, since only the St type bunkers were protected against a direct hit. It is also worth knowing that regulations allowed the B strength to be increased by 50% in very exposed positions, thus resulting in 3 thick walls and ceilings. The term splittersicher meant that the bunker was protected against shell fragments, while Schusssicher mean that the bunker could withstand a direct hit

On this page we will focus on the latter two types of bunker, verstärkt feldmäβig and ständig. What was special about these bunkers is that each type had its own unique characteristics, which were included in a 'catalogue' or Typenheft. This standardization process had enormous advantages:
  • The appropiate bunker types for a particular location could easily be selected as well as the number required.
  • Weapons, themselves standardized, could easily be fitted, as for each type it was described which weapons could be fitted in it.
  • It was immediately clear how much building material (concrete and steel) were required to build the bunker type.
  • It was also immediately clear how many labourers and how much time was need to complete the bunker type.
  • Most importantly and with the aid of the above information, the financial cost of building the type was known beforehand.
As part of this elaborate standardization proces each bunker type was given its own individual number. Thus, for example, a type Vf1a was uniformly known as an Unterstand bis 6 Mann (Hoyerbalken), splittersicher and a type 502 as a Doppelgruppenunterstand, i.e. a personnel bunker for 20 soldiers. The standardized ständige bunkers were known as Regelbauten.
