The O 21 class was a class of seven submarines, built for the Royal Netherlands Navy. The boats were still incomplete at the start of the German invasion of the Netherlands O 21, O 22, O 23 and O 24 were hastily launched and escaped to the United Kingdom. O 25, O 26 and O 27 were not able to escape and were captured by the German forces. The Kriegsmarine ordered the completion of the boats and they entered German service as UD-3, UD-4 and UD-5. The submarines diving depth was 100 meters (330 ft).
The file contains all the sounds and pcx files. Model is not my own creation. Wyrmshadow provided the animation files and Ares de Borg did the sounds. I merely put the pieces together and cleaned up the model for CivIII and added some what if pieces. A big thanks to everyone that helped out!
