Design and Construction

Rough design drawing of Group 3 Boats.[4]

The forward diving planes could swivel forward and conform to the side of the boat for better surface seakeeping.

Radio

By war's end, all boats of "E" class and later were given 3 kilowatt Poulsen wireless sets, affording ranges of 200 miles submarine-to-submarine, and 300-400 miles between shore stations and submarines. Reception of shore stations of 400 miles was common, and high power shore stations could be received over 500-600 miles.[5]
