The driving requirement would be a surface speed that matched the speed of the battlefleet. In order to meet the requirement, the DNC designed a three shaft submarine that was 100-foot (30 m) longer than the <a href="/wiki/British_E-class_submarine" title="British E-class submarine">E class</a>, with electric motors confined to the two outer shafts and a hull form based on a light cruiser.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> This resulted in a diesel-electric design that was unique within the <a href="/wiki/Royal_Navy" title="Royal Navy">Royal Navy</a>. </p><p>The power requirement was 1,200 <a href="/wiki/Horsepower" title="Horsepower">horsepower</a> (890 kW) per <a href="/wiki/Diesel_engine" title="Diesel engine">diesel engine</a>. In order to meet this power requirement, Vickers, the pre-eminent builder of submarine diesels in First World War Britain, elected to produce a 12-cylinder version of their previously successful 100 <a href="/wiki/Horsepower#Brake_horsepower" title="Horsepower">brake horsepower</a> (75 kW) per cylinder six- and eight- cylinder engines for the <a href="/wiki/British_D-class_submarine" title="British D-class submarine">D</a> and E classes respectively.

Although designed to reach 19.5 <a href="/wiki/Knot_(unit)" title="Knot (unit)">knots</a> (36 km/h), the boats could only practically travel at 19 knots (35 km/h), making them too slow for fleet use.

The early loss of both of these boats frustrated the submarine ambitions of the <a href="/wiki/Royal_Australian_Navy" title="Royal Australian Navy">Royal Australian Navy</a> (RAN), seeking a replacement for <i>AE1</i> as early as October 1914, and setting aside 125,000 pounds in the 1915–1916 estimates for this purpose, however the pressures of wartime meant there was no spare capacity in British yards. In 1916, the manager of <a href="/wiki/Cockatoo_Island_Dockyard" title="Cockatoo Island Dockyard">Cockatoo Island Dockyard</a> sent a party of ten to study submarine construction in Britain, the party returning in 1918.

They arrived in Sydney on 15 July 1919. </p><p>On arrival the need for a program of deep maintenance and battery replacement became urgent, given their arduous wartime service, limited maintenance, and breakdowns experienced on the voyage out. Short term repairs being made to all boats in late 1919, while <a href="/wiki/HMS_J3" title="HMS J3"><i>J3</i></a> and <a href="/wiki/HMS_J7" title="HMS J7"><i>J7</i></a> entered a deep refit in early 1920 that was to last more than a year, while the other four boats completed a program of peacetime exercises, cruises and port visits from their new base at <a href="/wiki/Geelong" title="Geelong">Geelong</a>, <a href="/wiki/Victoria_(Australia)" class="mw-redirect" title="Victoria (Australia)">Victoria</a>. Practice returns show that in the last quarter of 1920, the four operational boats made eighty submerged simulated attacks with 39 calculated to have hit. Management issues at Cockatoo Island delayed the refits of <i>J3</i> and <i>J7</i> by three months in early 1921. In March 1921, it was calculated that refit costs had reached 73,500 pounds for <i>J3</i> and 110,861 pounds for <i>J7</i>; the Admiralty had previously advised that the annual operating costs for these boats was 28,300 pounds.<sup id="cite_ref-auto1_7-0" class="reference"><a href="#cite_note-auto1-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p><p>In April 1921, a report to the board gave the status of the six submarines as follows:<sup id="cite_ref-auto1_7-1" class="reference"><a href="#cite_note-auto1-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p> <ul><li><a href="/wiki/HMAS_J1" class="mw-redirect" title="HMAS J1"><i>J1</i></a> Sydney Battery unsafe and must be replaced (could not dive).</li> <li><a href="/wiki/HMAS_J2" class="mw-redirect" title="HMAS J2"><i>J2</i></a> Sydney Heavy engine and battery defects, to enter refit when <i>J3</i> completed.</li> <li><a href="/wiki/HMS_J3" title="HMS J3"><i>J3</i></a> Sydney Most defects made good, new batteries arrived Cockatoo and unpacked.</li> <li><a href="/wiki/HMAS_J4" class="mw-redirect" title="HMAS J4"><i>J4</i></a> On Service, battery due for replacement December 1921</li> <li><a href="/wiki/HMAS_J5" class="mw-redirect" title="HMAS J5"><i>J5</i></a> On Service, battery due for replacement February 1922</li> <li><a href="/wiki/HMS_J7" title="HMS J7"><i>J7</i></a> New battery due in May, defects will be made good by December 1921.</li></ul> <p>The heavy expenditure on submarines, poor materiel condition of the fleet, and general cutbacks in naval expenditures in the wake of the war made it clear about this time (mid-1921) that the flotilla would have to be reduced to reserve. A plan was drawn up in July by Boyle with three boats remaining in service (<i>J3</i>, <i>J4</i>, and <i>J7</i>) with three laid up in reserve (<i>J1</i>, <i>J2</i>, and <i>J5</i>). This plan was authorised in August, and dredging, wharf construction, and reserve crews were performed at <a href="/wiki/Flinders_Naval_Depot" class="mw-redirect" title="Flinders Naval Depot">Flinders Naval Depot</a>. The plan was expected to save between 100,000 and 130,000 pounds per year.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </p><p>In early 1922, the operational boats completed exercises at Geelong and <i>J3</i> and <i>J4</i> participated in fleet exercises in Hobart. On 20 March, the dredging at Flinders was complete and <i>J1</i>, <i>J4</i>, and <i>J5</i> were steamed around from Geelong and laid up. Shortly after, the government informed the RAN that a further 500,000 pound cut to the naval estimates would be made, leaving the Naval Board with no option but to lay up all six boats. There were a number of proposals to run on a cadre force at minimal expense with the <i>J7</i>, the boat in the best condition, but these proposals were not taken up. All of the boats were progressively de-stored and sold off for disposal. Four of the submarines, <i>J1</i>, <i>J2</i>, <i>J4</i>, and <i>J5</i>, were scuttled in <a href="/wiki/Bass_Strait" title="Bass Strait">Bass Strait</a>, approximately 4 kilometres (2.2 nmi) west-southwest of the entrance to <a href="/wiki/Port_Phillip_Bay" class="mw-redirect" title="Port Phillip Bay">Port Phillip Bay</a>, and are currently popular scuba diving sites.
