Dimensions cited are for main body of class. E49 is evidently a late construction; wartime censorship restrictions evidently precluded a full description in Jane's.

This submarine was a unit of the E21 variant of the E class, and was built by Swan Hunter (on the Tyne) in 1916. She was mined off Shetland in 1917.

Built under the Emergency war Programme between 1913 and 1916, this class of submarine were all of Admiralty wing-tank type, and were the first British submarines to have beam tubes and to be internally subdivided by watertight bulkheads. The heavy losses sustained by this class (28 out of 58 being lost) reflect their status as the standard British submarine class in the First World War.

No accurate location is currently cited but the recorded discovery of the vessel 'between Balta and Huney Islands' suggests a location at about HP 655 068, in a charted depth of about 29m. The chart names this area South Channel but does not indicate the seabed type.
