South Korean Navy recently retrofitted their Type 209 and other submarines with digital camera based pericopes, replacing traditional periscopes. When the South Korean Navy procurement office requested proposal from traditional periscope manufacturers, the quoted price was astronomical. S Korean Navy said no thanks and had local manufacturers develop/test/manufacture a new digital camera based periscope at a FRACTION (like 10% ?) of the quoted price from traditional manufacturers.
