Prof Mercogliano & Dr C Discuss What is going on with Logistics(Shipping)? #2Historians Ep 5

Russia's inland fuel routes feed sea transfers, but aging river tankers have structural limits when pushed into exposed waters.

Two different assessments of canal vulnerability and escalation show why attacks on fuel routes could widen the war against merchant shipping.

A proposed explanation links apparent maintenance differences among Russia's Kilo-class submarines to political command appointments.

A reading of Mahan beyond decisive battle places trade, transport, and the protection of maritime commerce at the center of sea power.

Moving two armored divisions from Europe to Dammam in weeks illustrates the scale of Gulf War sealift.

The grounding of USNS Big Horn shows how losing one oiler can disrupt a carrier group and force improvised commercial support.

Amphibious ships can retain useful transport capacity for decades, supporting forces ashore and disaster relief without the upgrade demands of front-line escorts.

Japanese carrier mobility, early US Pacific operations, and the Falklands task force demonstrate how fuel determines a fleet's actual reach.

The Royal Navy's global carrier deployments show how operational tempo and steaming distance can consume service life and force postwar replacement.

Enterprise's return from Wake and the loss of Lexington's assigned oiler show how fuel availability could constrain or cancel an operation.

Flags of convenience and multinational ownership complicate naval protection while Houthi attacks divert trade around Africa.

The Houthi campaign becomes a case study in regional power, practical statecraft, and the economic consequences of imperfect defense.

Even highly effective missile defence may leave enough risk to raise insurance costs, divert shipping, and reduce Egypt's Suez Canal revenue.

A Royal Navy office tracking global shipping routes supplied the knowledge needed for HMS Liverpool to intercept Asama Maru near Japan.

The Shipping Act of 1916 created a major US merchant fleet, but political retrenchment and operating costs limited its postwar challenge to Britain.

Oil-fired merchant ships could carry fuel for long round trips, reducing their dependence on Britain's overseas coaling stations.

A larger merchant fleet needed competitive operating costs and profitable routes to survive after government support declined.

William Sims's arguments for large convoys, concentrated destroyers, and submarine suppression foreshadowed World War II escort doctrine.

Personal correspondence reveals how operational disagreements became accusations of national bias and shaped later naval leadership.

Small, heavily escorted convoys multiplied the demand for destroyers. Sims wanted scarce American destroyers concentrated in the Western Approaches, supported from Queenstown.

Taranto, dedicated antisubmarine escorts, and later American force development illustrate how navies carried earlier war experience into new plans.

Destroyers could protect a convoy by holding a submarine underwater until the merchants escaped, even when they could not reliably find and sink it.

Navies struggle to explain patrol, presence, and deterrence because success often looks like nothing happening.

The separation of auxiliaries from naval career paths can deprive senior commanders of practical experience in sustaining fleets.

William Callaghan's staff work and Lawson Ramage's submarine experience illustrate different routes to understanding naval sustainment.

The closure of Red Hill raises a question about the fuel reserves available to sustain a Pacific war.

Ships and trained reservists provide the depth needed when a supposedly short war becomes a contest of production and endurance.

An illustrative mobilisation sequence shows how trained reservists provide time and experienced leaders for an expanding wartime force.

A proposal for reserve destroyers and frigates considers both the ships' remaining utility and the replacement crews they could train.

Erie-class gunboats and River-class patrol vessels illustrate how presence missions can be covered without diverting high-end combatants.

A global escort network constrained U-boats, while loading limits and congested ports determined how much cargo shipping could actually deliver.

Flower-class corvettes and River-class frigates helped cover US East Coast and Caribbean gaps, showing that Lend-Lease aid ran in both directions.

Mass escort construction extended convoy protection across several oceans and narrowed the remaining opportunities for U-boats.

The Sherman's weight illustrates a proposed link between shipboard lifting limits and tank design, while port turnaround restricted wartime cargo delivery.

Convoy diversions and damaged docks show how a campaign against shore infrastructure can interrupt maritime trade.

Allied planners were slow to appreciate European barge traffic, even though canal locks and river routes could become decisive bottlenecks.

Mahan's long-form case for sea power contrasts with modern bullet-point advocacy, while sanctions show the cost of ignoring logistical adaptation.

Familiar civilian comparisons can explain the connections. Hurricane damage and interrupted electricity repairs show the consequences of losing normal logistical support.

Alternative insurance and a parallel tanker fleet form the basis of a critique of insurance-based oil-price enforcement.

A carefully orchestrated Coral Sea fuel plan contrasts with carriers arriving off Guadalcanal at only 60 percent fuel.

USS Cole entered Aden because no underway replenishment ship was available, turning a fuel requirement into a force-protection vulnerability.

British carrier plans, missile replenishment, and salvage capacity show why a fleet fails when its less visible supporting elements are omitted.

Reloading vertical-launch missiles at sea remains slow and constrained by the small number of equipped ships, magazine space, and handling arrangements.

A damaged warship may be lost unless specialized ships can tow and recover it from contested waters when commercial salvors will not enter.

The Falklands sealift and today's multinational crews show that requisitioning a ship does not automatically provide willing, trained mariners.

China's shipyards, merchant fleet, and overseas ports invite comparison with Britain's earlier maritime position and raise questions about protecting shipping against piracy.

Proposed British amphibious vessels and commercial landing-ship designs offer possibilities. Orders, survivability requirements, and a coherent plan for Pacific operations remain unresolved concerns.

Changing political priorities leave fleets with fragments of programs, while shrinking auxiliary forces remove the depth needed for operations.

Nimitz could anticipate carriers already under construction, while availability at short notice depends on how many existing ships can deploy promptly.

Task Force 11's 1942 Rabaul raid illustrates how combat speed can triple daily fuel use and make escort endurance the carrier group's limit.

Detailed policy arguments explain their evidence and distinguish reliable sources from weaker claims.

A cautious forecast for uncrewed naval vessels connects rules written for crewed ships with the risk that wartime restraint may break down.
