Echo Voyager, Boeing’s latest unmanned undersea vehicle (UUV), can operate autonomously for months at a time thanks to a hybrid rechargeable power system and modular payload bay. The 51-foot-long vehicle is the latest innovation in Boeing’s UUV family, joining the 32-foot Echo Seeker and the 18-foot Echo Ranger.
The size of the new Echo Voyager is in the middle of the German U-Boat lengths which were 40-60 meters [previously incorrect feet units in article] long depending upon design. the 51 foot long Boeing drone is about 40% of the length of the short U-boats.
U-boats dominated the seas for several years due to the fact that thousands were produced.
A militarized Echo Voyager could have a similar role if they were mass produced at low cost in the event of a conflict.
