Patreon 7 – How the RN countered E-Boats in the English Channel as proposed by Paul

British accounts often use E-boat for more than the famous Schnellboot, which can hide the wider German small-craft problem.

Yes. Postwar Vosper designs are the place to look for turbine-powered fast-craft development.

Motor gun boats brought the old torpedo-boat-destroyer mission back to the coastal war in a fast, heavily armed form.

Some early small craft, especially Fairmile Bs, could be used for anti-submarine work, although the category included more than converted motor gun boats.

A Channel patrol boat needed enough speed and endurance to cross, operate near the far shore, and return under darkness across a large search area.

The defenses were constrained by ships being withdrawn for maintenance, radar and gun upgrades, and final preparation for the invasion, while human mistakes also left gaps.

Any suitable convoy escort could engage torpedo boats when required, and those larger escort types carried as much useful armament as their duties allowed.

Because the stream follows the British wartime perspective, in which E-boat was the Allied label commonly applied to the German Channel threat.

Not to the same degree, because the Irish Sea was generally too far from German bases for the E-boats' practical operating range.

A Schnellboot combined high speed and useful range with a relatively modest gun battery, while sea conditions reduced what headline figures meant on operations.

There may have been a few, but the dominant Irish Sea requirements were anti-submarine and anti-aircraft escort, for which armed trawlers were often adequate.

No; a Schnellboot caught by a Tribal-class destroyer's much heavier gun battery was in a very unfavorable fight.

British motor gun boats posed the greatest danger, especially the heavily armed Dog Boats that hunted Schnellboote at very close range.

They normally carried two ready torpedoes and two reloads, although a special mission could justify leaving the reloads behind to reduce weight.

No simple national split applies here. Most of the small boats under discussion were built from carefully planed wood.

Yes; fittings allowed boats to carry mines on either side in place of torpedoes when the mission called for minelaying.

There is no exact match. A modern German candidate is far larger, while Iranian fast attack craft approach the role without fully reproducing it.

Small-boat operations usually took place at night, while uneven RAF and Royal Navy coordination limited how reliably air power could solve the surface threat.

No. That scale represents a major-operation concentration, with perhaps eighteen to twenty-four craft actually reaching the target area rather than fifty or sixty fighting as one routine attack.

Britain had begun small-craft preparations before the war, but the fall of Norway and France vastly increased the coast and convoy network that required defense.

Modern patrol boats have far better sensors, but their policing and presence mission is different; armed small craft would supplement rather than replace frigates and destroyers.

Later Vosper boats raised the bow around the torpedo launchers, improving their behavior in rough water and slightly increasing speed.

After taking over a Vosper boat during Dunkirk, Admiral Ramsay became an unusually forceful institutional champion for motor torpedo boats and related craft.

Fairmile's wooden craft depended on standardized templates, large timber supplies, and a production system able to absorb rapid wartime development.

Neither design was universally superior: British boats were shaped for rough, close-range Channel and North Sea fighting, while American PT boats were optimized mainly for Pacific operations.

Vosper developed a private-venture boat around high speed, torpedoes, a gun, moderate-sea ability, and a full night crossing to enemy waters.

Yes; many became ferries, pleasure craft, or houseboats, and the surviving Steam Gun Boat Grey Goose was living a civilian afterlife as a houseboat.

Yes. Consolidation encourages more groupthink by reducing the number of independent design organizations.

French command-and-control problems were judged so deep that the only workable counterfactual required British communications teams at every level.

Britain relied on coastal shipping to distribute imported materials between ports when road and rail capacity could not carry the whole wartime load.

Britain's braking practice did not force wartime trains to move very slowly, though coastal shipping remained necessary.

The Fairmile D could carry an exceptional mix of guns, torpedoes, depth charges, mines, and later sensors for a small craft.

Yes. The boats were used for many experiments, although this exchange does not identify a specific rocket system or its results.

The idea is tempting, but such boats would supplement larger warships, and peacetime rules would probably prevent wartime-style crew modifications.

Yes. The boats obtained the high-octane fuel.

Not comfortably or usefully. Engine noise would be severe, especially aboard a boat fitted with Griffon engines.

The Channel Dash put British motor torpedo boats into a high-risk daylight attack against major German ships, an exceptional mission for normally nocturnal craft.

Built-in deck fittings allowed Fairmile B motor launches to be reconfigured quickly for many small-craft missions.

No. A major warship attracts attack and therefore also attracts extra attention and defensive preparation.

Operation Chariot demonstrates how Fairmiles and motor torpedo boats supported a combined raid to deny St Nazaire's great dry dock to German capital ships.

A possible design is a fast, modular 250- to 300-ton craft with a medium gun, naval strike missiles, possible surface-to-air weapons, useful range at about 40 knots, and some stealth shaping.

Coastal-force command frigates were useful when they supplied capabilities smaller boats lacked, but radar-equipped Dog Boats could possess the better local tactical picture.

Enigma intelligence, radio listening, radar, and a favorable destroyer formation gave Allied forces the advantage at the Battle of Ushant.

Enigma and the less famous Headache listening system exposed German movements before Allied destroyers made radar contact at Ushant.

The leading Allied destroyers used radar and a line-abreast formation to widen their front and reduce the danger of one German torpedo spread striking multiple ships.

D-Day coastal-force patrols screened the invasion, intercepted enemy surface movements, and maintained a hard nightly barrier near the assault routes.

German forces were recovering from earlier losses and pressure, and the craft that did approach were often driven off before they could attack effectively.

The small Steam Gun Boat class received individual names and changing weapon fits, while Grey Goose survived the war through conversion to a houseboat.

E-boats normally meant Schnellboote, while R-boat referred to German Räumboote, principally minesweepers that could also perform other tasks and varied widely in size.

Its roughly 275-ton displacement allowed some protection around the machinery, unlike the far lighter boats that could carry little armor.

Most small boats had little armor; some British craft protected limited areas, while Steam Gun Boats carried more protection than many lighter counterparts.

The lasting answer to E-boats was rapid-firing guns, early detection, practiced tactics, and sufficient escort numbers to keep the system operating.

Fast turns, fragile hulls, and extremely short firing ranges made coastal actions resemble fighter combat more than battleship gunnery.

Only partly. It extended high-speed planing ideas, but it is closer to the Schnellboot tradition because a hydrofoil cannot easily carry the Dog Boat's adaptable heavy weapons load.
