It was originally intended to fit a 4-inch (102 mm) gun on the foredeck, but this was dropped due to the adverse effect it would have had on submerged speed.

Ordered in
December 1917, the R class were designed to be faster underwater than on the surface, achieving a submerged speed of 14 knots (26 km/h; 16 mph) versus a surfaced speed of 9 knots (17 km/h; 10 mph). They were well-streamlined, having no external ballast tanks, casing, or

Thirty-five per cent of the space inside the pressure hull was occupied by machinery. A single 8-cylinder 480 hp (360 kW) diesel engine was installed for surface propulsion, while high underwater speed was given by two large electric motors arranged one behind the other to drive the single

submarines. The large battery was, however, sufficient for only about an hour at full power. In addition, the engine took a full day to charge the batteries, using half its power. Charging was therefore undertaken in harbour, using a supply of electricity from the shore or from special battery

Despite being designed for maximum underwater performance, the R-class submarines were extremely difficult to control submerged, especially at high speeds. Surfaced, they had poor seakeeping and were slow. Minor modifications were made to
