Patreon 88: Sydney Strategy: When looking for a Far East Naval Base - what if Sydney not Singapore?

The opening comparison separates Sydney's industrial advantages from Singapore's stronger geography, logistics, and control of communications between India and Australia.

The Sydney scenario is built by comparing archival arguments, parliamentary debates, and opposing interpretations rather than granting Britain unlimited money or changing every strategic condition.

American criticism of the Singapore base could also support the domestic case for developing comparable naval infrastructure in Hawaii.

Rear Admiral Sir Herbert Richmond's Far Eastern war plan used Singapore as an assembly base before advancing through Hong Kong and Weihaiwei to blockade Japan with submarines and cruisers.

It did field dedicated and mine-capable submarines, but Far Eastern range requirements made the task different from Germany's coastal campaign.

A station-by-station survey shows why Indian, Chinese, and Australian alternatives each carried greater political, geographic, or infrastructure costs than Singapore.

Mostly preservation and consolidation of the post-First World War status quo, not major new expansion.

It was American rather than British, so it mattered mainly as an allied springboard in a joint war against Japan.

There were coherent plans, but some prepared positions were left unmanned as the staff and command system failed.

There was enough space to build a base capable of accommodating the entire Royal Navy fleet.

Thailand's later wartime alignment should not be projected backward into the 1920s, when it stood closer to Britain than to Japan.

Australia and New Zealand favored renewing the Japanese alliance, while Canada feared its effect on relations with the United States and helped force a British strategic choice.

Japan's capture of German-held Tsingtao, Mediterranean anti-submarine service, and offer of capital ships after Jutland underpinned dominion confidence in the alliance.

Singapore had an earlier island railway, and the Johor-Singapore Causeway added the mainland rail connection in the late 1920s.

Building a Far Eastern base served as visible proof that Britain intended to reinforce Australia and New Zealand rather than leave them strategically isolated.

Parliamentary opposition treated Singapore as an expensive new commitment, while supporters presented it as a long-term logistics hub and guarantee of imperial communications.

Discussion keeps an option under consideration, while entertaining it means moving toward action when it becomes viable or necessary.

Opponents alleged that Singapore evaded restrictions on Hong Kong, while the wider argument centered on electoral pressure and whether Britain would fund distant security before a crisis.

Many parliamentarians reasoned in European distances, while the Army and RAF treated the Far East as a naval problem because they could not project force across it.

Singapore won on treaty freedom, chokepoint geography, and local subsidies; a Sydney alternative requires Australia to outbid those advantages by funding the base.

Nelson and Rodney were already ordered and laid down by 1922, so the 1924 Sydney divergence affects later ships and refits rather than their basic design.

Moving the theater-entry base from Singapore to Sydney raises the key voyage from about 5,365 to 9,644 nautical miles and forces longer-ranged ships and more fleet oilers.

The 9,644-nautical-mile route from Suez to Sydney creates gaps between fixed bases that must be bridged by more refueling stops and earlier at-sea logistics.

A cruiser-driven push for efficient boilers could spill into 1930s reconstructions of Renown, Hood, Nelson, and Rodney.

Expanding Garden Island and Cockatoo Island into a fleet hub creates capital-ship repair capacity and a political need to coordinate British and dominion forces under one theater command.

Yes; its largest dock could handle HMS Hood, though historically there was only one dock of that size.

Treaty-era declarations and the wartime repurposing of internal tanks could obscure how much fuel endurance a British warship actually possessed.

Sydney would gain floating-dock reinforcement, while mobile naval-base units carried repair capacity forward as Britain retook Hong Kong and established itself at Weihaiwei.

RAF staff meant no strike aircraft, while the Navy heard that no fighters or strike aircraft were available at all.

Protecting both Singapore's chokepoint and Sydney's fleet hub creates continuing demand for 15-inch guns, Australian shell production, and ammunition stockpiles across the Empire.

A prewar five-star British Empire commander in Sydney would compete with MacArthur and could inherit coalition command when the Philippines fell.

A senior Far East headquarters in Sydney would require better rail and administrative links with Canberra, making land transport part of the naval-base program.

Turning Sydney into a strategic fleet target brings earlier investment in fighters, warning radar, radar manufacturing, and long-range maritime patrol.

Australia developed radar, but not that early; the Sydney fleet base would likely accelerate an equivalent system.

Probably not; Sydney has a defensible harbor and substantial existing naval infrastructure to build upon.

The 10,000-mile requirement favors narrower, more efficient battleships and carriers, possibly with nine 15-inch guns and high-pressure machinery.

Probably not; the deputy would more likely be Australian, with separate land, air, and naval commanders beneath the British theater commander.

Replacing the 5.25-inch secondary battery with smaller twin 4.5-inch mounts could save beam and weight on the counterfactual long-range battleship.

Potentially, but the conversion would require extensive work for little gain.

Japan still strikes Pearl Harbor first, but a Sydney-centered repair and command system can send a balanced carrier task force toward Malaya instead of the historical Force Z.

The scenario's largest consequence is a decade of theater-level coordination that exposes weak plans, aligns the services, and makes Far Eastern defense politically accountable.

Before taking Singapore, Japan would struggle to concentrate naval forces against a British relief force operating along Malaya's west coast.

No; British planning treated the Far East as a naval theater, with the RAF and Army supporting the Royal Navy.

Germany, Italy, and Japan imposed different escort, capital-ship, carrier, and repair demands that Britain's interwar funding never fully reconciled.

A Japanese estimate required roughly ten infantry divisions for an invasion of Australia, a force the country did not have available.

A political struggle between Douglas MacArthur and the established five-star Far East commander could disrupt it.

A senior Far East headquarters could question dispersing Canadian troops to Hong Kong and building more airfields than available aircraft and ground forces could defend.

Not simply more Ark Royals; it needed a role-balanced carrier fleet and would likely favor Implacable-type ships if tonnage permitted.

It could probably build its own destroyers and full-size cruisers.

The altered basing and repair system could produce an early-1942 carrier clash involving British, American, and Japanese forces in the Coral Sea.

Yes; insufficient long-term investment weakened the industrial base and skilled workforce needed for naval construction.

The result depends on the war's course, but long-standing joint command would reshape cooperation and personnel experience.

The United States loses most, with Japan also disadvantaged, because both favor larger strike carriers.

It would probably need somewhat more boiler power, and the added weight and hull stress would be the more serious constraint.

He might have approved, because multiple triple 9.2-inch turrets could have produced capable large cruisers and influenced later designs.
