==Design and Construction==

[[File:TH21Plate6.jpg|thumb|800px|'''Rough design drawing of Group 3 Boats.'''{{UKTH21|Plate 6}}]]
 +
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.{{UKTHVol3Part21|pp. 16-17}}

H 28, probably shown upon her acceptance.[1]

The Royal Navy's "H" Class Submarines were manufactured in Britain, America and Canada to a design similar to the American "H" class boats. They were considered coastal submarines.[2]

Characteristics[3]
  Groups 1 & 2 Group 3
Length (feet) 150 164
Breadth (feet) 15.25 ditto
Displacement (tons) 364/434 440/500
Draft 12-ft 4-in ditto
Speed (knots) 13/11 ditto

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]

Torpedoes

Group 1-2:

  • four 18-in tubes forward

Group 3:

  • four 21-in tubes forward, six-eight torpedoes

Guns

H1 - H 4:[Citation needed]

  • one 6-pdr Q.F. gun

Others:[6]

  • None
