A Question of Getting There – Landing Craft & Amphibious Warfare Part 1

Engineers' own accounts, including work chaired by Director of Naval Construction Stanley Goodall, explain how landing craft were designed and built.

See why ordinary ships' boats worked for many earlier landings, and how Gallipoli drove the Royal Navy towards armoured X-lighters.

Usually navies relied on their ships' boats, which were adequate while most landings were made without concentrated resistance on a prepared shore.

Reginald Henderson's wartime staff work examined Gallipoli's naval failings and helped underpin the Royal Navy's adoption of convoys.

Interwar Britain retained amphibious expertise through a joint committee, new craft, recurring exercises, and Henderson's inter-service reform.

They were large, sturdy, near-seagoing barges that handled choppy water and could be supplied from an established production base.

Yes, strongly, but Tsingtao and observation of Royal Navy activity in the Indian Ocean were also important.

It could have tried, but the leadership was no longer willing to accept more casualties.

A 1924 exercise report already identified shallow-draught armoured craft, direct naval gunfire, heavy-equipment handling, sectional jetties, tides, and air defence.

Not in Britain, but Ceylon's exercises often used Gurkha brigades, while Royal Marines generally operated in smaller detachments.

Follow the interwar Motor Landing Craft as heavier tanks drive its evolution into the Landing Craft Mechanized.

Each craft had six crew, with one officer assigned for every three craft rather than one officer aboard each boat.

The Landing Craft Assault became a mass-produced troop carrier, while machine-gun-armed support variants fought close to the beach.

At Namsos, Adrian Carton de Wiart and Peter Fleming confronted the same unloading, fire-support, and air-cover problems already reported in 1924.

Not much in some cases; others carried light weapons such as machine guns, especially the dedicated support variants.

British and American officers both examined Higgins designs, producing fast personnel craft and the larger LCM Mark III.

The Royal Navy anticipated heavier tanks before the war and developed LCT variants that became essential to Allied invasion fleets.

Operational experience showed that landing forces needed both close gunfire and dedicated anti-aircraft craft near the beach.

See how the LCT Mark IV simplified tank lift for mass production, then gained extra strengthening for planned Far Eastern assaults.

Dieppe confirmed that a heavy assault was not a light raid and that effective landing-craft gun platforms needed size and stability.

See how a fast 200-man raiding requirement became the nearly 400-ton Landing Craft Infantry (Large), with American construction protecting British destroyer capacity.

Yes, but the lecture does not expand on the Hunt-class design story.

See the Royal Navy enlarge support craft until converted LCTs could carry destroyer-calibre guns close to defended beaches.

Some craft rode aboard landing ships, while others needed to transport themselves and heavier payloads; the latter required larger hulls.

A promising fast successor to the LCA remained a small program because changing course made little sense once the established assault craft was already in mass production.

Fairmile offered a smaller British-built counterpart after the large Landing Craft Infantry went to American yards to protect destroyer capacity.

Heavy ships had the power, but close targets could be obscured or require faster reaction; destroyers and armed landing craft could engage from much nearer the troops.

Far Eastern distances produced larger LCTs with troop accommodation and armoured gun craft carrying 17-pounders or 25-pounders.

Converted LCTs carried roughly a thousand rocket projectors to saturate a beach with explosives in seconds.

They were Britain's strongest readily available anti-tank weapon, with 25-pounders providing an even heavier alternative for shore bombardment.

No. It covered the principal designed types, while theatre commanders and crews produced many additional conversions and local variants.

They were often the same or closely related because British and American officers observed, ordered, and adapted designs from one another.

Yes. Crews counterflooded, beached craft, and changed weight distribution to obtain useful firing angles.

The reported aim was to demolish both the pillbox and the hill beneath it, but the episode had not been independently checked.

Available local craft and sloops landed troops and provided support in an operation that was not strongly opposed.

Very little; strong naval fire support overwhelmed the defences, so the operation revealed few new landing-craft requirements.

Possibly in isolated unofficial conversions, but the suggested Churchill Crocodile-derived arrangement lacks photographic or official confirmation.

They were optimized for different beach materials, reefs, surf, and operating conditions.

Much like those later ships, with an internal docking basin carrying large landing craft; wartime landing ship dock designs were already moving in that direction.

The beach's geography strongly favoured the defence, and the assault needed more effective firepower and possibly more tracked landing vehicles.

The oceans, beaches, reefs, and approach conditions differed, so each theatre rewarded different craft.

Britain considered many ruthless anti-invasion measures, but this exchange does not verify a particular gas plan.

Britain used some, but not extensively; their limited role helped prevent the capability from becoming central to the postwar Royal Marines.

They must be a combined operation, with naval firepower, air support, and ground forces coordinated through a dual command structure.

Yes, but the lecture gives no details about a particular plan or operation.

LCTs were larger, carried more weight, and were much more capable of travelling under their own power; LCMs generally required transport.

Tidal ranges, wave heights, and related coastal conditions are major design factors.

Probably around sixty, but late deliveries and post-operation commissioning make the exact figure uncertain.

They joined recurring exercises and smaller shipborne operations, but did not yet operate as a brigade-sized amphibious force.

A battleship was unnecessary for the concept, and the option had been considered.

Several wartime ideas anticipated it, but they had not yet developed the later Mexeflote's powered capability.

They sometimes bashed through, while clearance divers and Army engineers also demolished obstacles.

Naval and Marine companies formed early beach parties during exercises, but the main invasion brigade was an Army formation.

It depends where the missile hits; belt armour changes the effect, while another hit could still produce a mission kill without sinking the ship.

Through the wider Atlantic convoy system that carried wartime supplies to overseas forces.
