Design
Like all post-E8 British E-class submarines, E34 had a displacement of at the surface and while submerged. She had a total length of and a beam of. She was powered by two Vickers eight-cylinder two-stroke diesel engines and two electric motors. The submarine had a maximum surface speed of and a submerged speed of. British E-class submarines had fuel capacities of of diesel and ranges of when travelling at. E34 was capable of operating submerged for five hours when travelling at.E34 was armed with a 12-pounder QF gun mounted forward of the conning tower.
Like the other E-class minelaying submarines, E34 had three 18 inch (450 mm) torpedo tubes instead of five: two in the bow and one in the stern. Six torpedoes were carried. The two broadside torpedo tubes were replaced by mine tubes carrying a total of twenty mines.
E-Class submarines had wireless systems with power ratings; in some submarines, these were later upgraded to systems by removing a midship torpedo tube. Their maximum design depth was although in service some reached depths of below. Some submarines contained Fessenden oscillator systems.
