The E-class boats had a designed diving depth of {{convert|100|ft|m|1}}, but the addition of watertight [[bulkhead (partition)|bulkhead]]s strengthened the hull and increased the actual diving depth to {{convert|200|ft|m|1}}.<ref name=BR4/> The crew consisted of 34 officers and [[naval rating|ratings]].<ref name=g7>Gillette, ''Australian & New Zealand Warships, 1914–1945'', p. 47</ref>

This arrangement gave the E-class submarines a maximum speed of {{convert|15|kn|lk=in}} while surfaced and {{convert|10|kn}} submerged.<ref name=g7/> They carried approximately {{convert|40|LT|t|0}}<ref name=BR4/> of [[fuel oil]] that gave them a range of {{convert|3000|nmi|lk=in}} at {{convert|10|kn}} while on the surface<ref name=g7/> and {{convert|65|nmi|abbr=on}} at {{convert|5|kn}} while submerged.<ref name=BR4/>
