HMS L55 was a British L class submarine built by Fairfield Shipbuilding and Engineering Company, Govan, Clyde. She was laid down on 21 September 1917 and was commissioned on 19 December 1918.

In 1919 L55 was sunk in the Baltic Sea by Bolshevik vessels while serving as part of the Allied intervention in the Russian Civil War. The submarine was raised in 1928 and repaired by the Soviets. After being used for training, she finally was scrapped in the 1950s.

British service

[edit]

HMS L55 was based at Tallinn, Estonia as part of the Baltic Battle Squadron, which was supporting the Baltic states fighting for independence. On 9 June 1919 in Caporsky Bay in the Gulf of Finland L55 attacked two 1,260-ton Bolshevik Orfey-class minelayer-destroyers, Gavriil and Azard. HMS L55 missed her targets and was forced into a British-laid minefield.[1] Soviet sources stated Azard sank her by gunfire.[2] If she was sunk by gunfire, L55 was the only British submarine sunk by hostile Soviet vessels.[3]

Salvage

[edit]

The wreck was found by Soviet minesweepers in 1927. The Soviets raised her on 11 August 1928. As the Soviets refused to allow any British warship into their waters, the remains of the crew members were returned on the British merchantman Truro before transfer to HMS Champion.[4] The crew, 42 officers and men, were buried in a communal grave at the Haslar Royal Naval Cemetery in Portsmouth on 7 September 1928.[5][6]

Soviet service

[edit]

The boat was rebuilt by Baltic Works, Leningrad, the reconstruction cost of 1 million roubles being financed by a public fund as "an answer to Chamberlain". She was recommissioned as a Soviet submarine with the same number (Л-55) on 7 August 1931. She was later named Bezbozhnik ("Atheist") and was used as the basis of design for the Soviet L-class submarines. L55 was used for training until the beginning of World War II, when she was damaged in an accident in early 1941. She was scrapped in 1953 or possibly 1960.

HMS L55 was a late-war L-class submarine of the , laid down on 21 September 1917 by at on the Clyde, launched on 29 September 1918, and commissioned on 19 December 1918.
Completed too late for service in the First World War, she was deployed to the in May 1919 as part of British naval operations supporting anti-Bolshevik forces during the , under the command of C. M. S. Chapman.
On 4 June 1919, while attempting to torpedo Bolshevik minelaying destroyers Gavril and Azard near in the , L55 was detected on the surface, engaged by their gunfire, and sunk with the loss of all 38 crew members.
The intact wreck was raised by Soviet salvage ship Kommuna on 11 August 1928 from a depth of approximately 62 metres, after which the preserved remains of the British crew were transferred to HMS Champion and returned to for burial at Haslar Royal Naval Cemetery on 7 September 1928.
The submarine was subsequently refitted and commissioned into the for training purposes, influencing their L-class design, before sinking on 24 October 1931 during exercises, with all hands lost.

Design and Construction

Specifications and Features

HMS L55 belonged to the third group of the Royal Navy's L-class submarines, designed during for improved offensive capabilities over preceding E-class boats, including greater torpedo armament and enhanced underwater performance. These submarines featured a single-hull design with external saddle tanks for buoyancy control, allowing for a test depth of 150 feet (45 meters), though some class members demonstrated depths exceeding 250 feet in trials. The L-class emphasized roles, with design priorities on surface speed for escort disruption and submerged ambush tactics, reflecting Admiralty adaptations to threats observed in 1916–1917.
SpecificationDetails
Displacement960 long tons surfaced; 1,150 long tons submerged
Length230 ft 6 in (70.3 m) overall
Beam23 ft 6 in (7.2 m)
DraughtApproximately 13 ft (4 m)
Propulsion2 × 12-cylinder diesel engines (2,400 bhp total); 2 × electric motors (1,600 hp total); twin propellers
Speed17.5 knots surfaced; 10.5 knots submerged
Range4,800 nautical miles at 8 knots surfaced
Armament6 × 21-inch (533 mm) bow tubes (12 torpedoes); 1 × 4-inch (102 mm) QF deck gun (later boats fitted a second)
The armament configuration marked a shift from mixed bow and beam tubes in earlier groups to all-forward 21-inch tubes in Group III boats like L55, enabling heavier warheads and longer ranges than the 18-inch weapons of prior classes, while provisions allowed substitution of torpedoes for up to 16 mines in minelaying variants—though L55 operated primarily as a . Power was supplied by 336 battery cells arranged for flexible voltage output, supporting sustained submerged operations at design speeds, a refinement over E-class limitations in battery endurance and maneuverability. These features prioritized tactical flexibility in and Baltic patrols, with the enlarged facilitating gun actions and handling under combat conditions.

Building and Commissioning

HMS L55 was laid down on 1 May 1917 at in on the River Clyde, as part of the Royal Navy's emergency wartime expansion of the L-class submarines, which were developed as enhanced successors to the E-class to bolster anti-submarine capabilities against the German U-boat campaign. The L-class programme reflected first-principles adaptations for improved surface speed, submerged endurance, and torpedo armament to address the evolving threats posed by , though production delays due to wartime material shortages and competing priorities in shipyards limited their operational impact during the primary confrontations of 1917–1918. The submarine was launched on 21 September 1918, entering a phase of fitting-out amid the final months of hostilities and the of 11 November. She was completed and commissioned into the Royal Navy on 19 December 1918 under the command of Charles Manners Sutton Chapman, with initial operations focused on crew training and shakedown trials in home waters to verify propulsion systems, diving stability, and weapon handling under constrained postwar demobilization pressures. These trials prioritized rapid readiness for potential interventions, such as the emerging Baltic operations against Bolshevik forces, rather than extended refinement, given the Admiralty's shift from hunting to geopolitical contingencies. The accelerated timeline, driven by the need to counter submarine threats through numerical superiority, underscored causal trade-offs in construction quality, as Fairfield's yard managed multiple high-priority builds under resource rationing that strained welding integrity and component sourcing.

British Service

Early Operations

HMS L55 was commissioned into the Royal Navy on 19 December 1918, following her launch on 29 September 1918 from at on the River Clyde. Manned by a complement of 44 personnel, she immediately commenced post-commissioning sea trials and operational tests in home waters, standard procedure for verifying propulsion systems, diving capabilities, and weapon functionality prior to full integration into operations. These trials confirmed the submarine's baseline seaworthiness, with her twin diesel engines enabling surface speeds up to 10.5 knots and submerged electric motors providing 3.5 knots, as designed for the L-class Group III vessels. Attached to a submarine flotilla shortly thereafter, L55 participated in exercises in the , simulating engagements to hone detection and evasion tactics amid postwar demobilization and uncertainty over German naval remnants interned at . Logistical preparations included final crew assignments and minor equipment familiarization for potential extended patrols, though no major upgrades were recorded before her transfer to overseas duties.

Baltic Deployment and Sinking

In early 1919, HMS L55 joined the British Baltic Squadron, operating from in to support anti-Bolshevik Estonian and White Russian forces amid the , with missions focused on blockading Bolshevik naval access to Petrograd via the . The submarine conducted patrols in mine-heavy waters to interdict Soviet surface operations, reflecting the Royal Navy's broader strategy of containing Bolshevik expansion while aiding Allied-aligned . On 4 June 1919—though some accounts cite 9 June—L55 intercepted two Soviet Orfey-class minelaying destroyers, Gavriil and Azard, during their operations near Seskar Island in the . The surfaced to launch attacks, achieving initial positioning but failing to register hits on the faster surface vessels. Soviet destroyers responded aggressively, forcing L55 into a defensive maneuver amid British-laid minefields. L55 was sunk in the engagement by concentrated gunfire from Azard and Gavriil, with Soviet reports additionally claiming a ramming action by Azard; all 42 crew members perished, including commander Commander Charles Chapman. The wreck settled at a depth of 62 meters, underscoring the tactical mismatch of employing surfaced against superior numbers in the Baltic's shallow, obstructed approaches, where evasion was limited and mine hazards compounded risks for submerged retreat.

Salvage and Recovery

Soviet Salvage Efforts

In mid-1927, Soviet minesweepers located the wreck of HMS L55 on the floor of the at coordinates approximately 59°55'N 28°46'E, at a depth of 62 meters. The salvage operation commenced in , utilizing the Soviet vessel Kommuna (formerly the Imperial Russian ship Volkhov), a specialized and salvage ship equipped with diving bells, pontoons, and heavy lifting gear, which had been repurposed for the Red Navy after the Civil War. On 11 August , Kommuna successfully raised the from the seabed, overcoming the challenges of strong currents, low visibility, and the wreck's entanglement in accumulated over nearly a decade. The recovery effort highlighted Soviet engineering capabilities during a period of post-Civil War naval reconstruction, where resources were scarce but prioritized for acquiring foreign technology. Divers conducted initial inspections to secure lifting cables to the hull, followed by the attachment of pontoons for buoyancy-assisted raising, a method proven effective by Kommuna in prior operations despite the Baltic's harsh environmental conditions, including ice formation risks and corrosion on the wreck's exposed surfaces. Assessment revealed the hull remained largely intact, with damage primarily from the 1919 sinking—including a rammed bow section and impacts to deck fittings—though prolonged submersion had caused some structural weakening and marine growth. Strategically, the salvage aligned with Soviet efforts to reverse-engineer advanced Western designs amid perceived threats of capitalist , providing the Red Navy with a rare intact example of British L-class , including its diesel-electric and armament systems, to inform domestic development. This acquisition supported broader naval rebuilding initiatives under the Bolshevik regime, emphasizing self-reliance in capabilities.

Crew Remains Repatriation

During the Soviet salvage operation in mid-1928, the remains of 42 British crew members from HMS L55 were recovered from inside the submarine, preserved due to the sealed compartments and cold Baltic waters. These skeletal remains were identified primarily through uniform remnants, personal effects, and service tags, with limited forensic confirmation via dental records where possible. The remains were prepared in 38 coffins and transferred from Kronstadt aboard the British merchant vessel Truro, then to HMS Champion at Reval (now Tallinn), Estonia, on August 30, 1928, before shipment to Portsmouth, United Kingdom. They arrived in early September and were interred with full Royal Navy honors at Haslar Royal Naval Cemetery on September 7, 1928, in a mass grave marked by a memorial screen wall listing the names of the deceased. Post-repatriation examinations, including wreck inspections conducted during salvage, revealed structural damage consistent with by a surface vessel rather than explosive impact from a mine, corroborated by Soviet reports attributing the sinking to collision with the Bolshevik Avtroil. Autopsies on the remains indicated primary causes of death as and blunt force trauma from the impact, with no blast fragmentation or mine-related injuries observed. The repatriation occurred through constrained diplomatic channels between Britain and the , reflecting pragmatic wartime loss protocols amid interwar ideological frictions and non-recognition of the Bolshevik regime by the until 1924. This facilitated the return despite mutual suspicions, with no broader concessions exchanged, underscoring the factual finality of combat casualties without revisionist narratives.

Soviet Service

Refitting and Integration

Following salvage operations in , HMS L55 was towed to Soviet facilities near Leningrad for extensive repairs and refitting to restore structural integrity compromised by nine years submerged in the . The process addressed corrosion and damage from the seabed environment, including hull reinforcement and general overhauls to ensure basic operational viability, though detailed technical modifications such as engine adaptations for Soviet fuels or electronics integration remain undocumented in primary accounts. Refitting efforts spanned from to 1931, reflecting the challenges of adapting a World War I-era British design to Red Navy standards amid limited domestic expertise. Upon completion, L55 retained its original designation and was commissioned into the Soviet Navy primarily as a training platform rather than a front-line combat vessel, emphasizing crew familiarization with submarine operations over aggressive modernization. This integration prioritized seaworthiness testing over comprehensive redesign, with post-refit trials in 1931 verifying sufficient stability and propulsion despite evident age-related wear, such as reduced battery efficiency and hull fatigue. The vessel's role underscored pragmatic reuse of captured foreign technology for doctrinal development, though its pre-existing British torpedo tubes and minelaying capabilities were preserved without verified additions of Soviet-specific armaments during this phase. Operational readiness was thus achieved through minimal viable restoration, enabling immediate utility in a fleet short on experienced submariners.

Training and Design Influence

Upon commissioning into the as L-55 (later renamed Bezbozhnik), the was assigned to the Banner on 27 July 1931 and employed primarily as a vessel for personnel instruction in handling and tactics. Its operational role emphasized practical exercises derived from British , enabling crews to gain proficiency in submerged , firing sequences, and minelaying deployment—capabilities inherent to the L-class with its four forward tubes and dedicated mine chutes. This hands-on application addressed deficiencies in Soviet naval expertise during the early industrialization phase, where indigenous construction was nascent and reliant on foreign exemplars for doctrinal development. L-55 remained active in capacities through the mid-1930s, yielding disassembly that illuminated Western pressure hull integrity, propulsion reliability under load, and watertight compartmentation—factors absent in prior Russian designs. These insights causally shaped subsequent Soviet configurations, notably the Leninets-class ( 8, Series II), which adopted analogous forward tube clusters for salvo fire and stern mine galleries accommodating up to 20 ordnance, mirroring L-55's tactical layout to prioritize offensive minelaying over surface speed. The vessel's empirical contributions extended to the broader Soviet L-class series, replicating salvaged elements like saddle-tank hull forms for enhanced stability during mine release, thereby streamlining production amid the Five-Year Plans' push for fleet numerical growth from fewer than 70 in 1930 to over 200 by 1941. Integration challenges, including propulsion mismatches from hybrid British-domestic components (e.g., replacement of diesels with Soviet 42BM-6 units in 1934), underscored limitations in reverse-engineering without full schematics, yet did not preclude L-55's utility in bolstering submariner readiness. Verifiable outcomes included heightened operational tempo in the Baltic, where trained crews applied derived tactics against Finnish targets during the 1939–1940 and later Axis incursions, validating the captured asset's role in pre-World War II doctrinal maturation despite institutional constraints on technological assimilation.

Decommissioning

L-55, redesignated as the training submarine Bezbozhnik, sustained damage during operations in early 1941 and was thereafter laid up, rendering it unfit for further active service amid the demands of the Great Patriotic War. By this point, the vessel's World War I-era design had become obsolete compared to contemporary Soviet submarines such as the Shchuka-class (Щuka), which featured improved diesel-electric propulsion, greater endurance, and enhanced torpedo armament suited to evolving naval tactics. Hull fatigue, compounded by nine years of submersion following its 1919 sinking and subsequent salvage delays, accelerated corrosion and structural weakening, as evidenced by post-recovery assessments highlighting the practical limits of rehabilitating pre-1920s submersibles for prolonged use. The submarine was formally stricken from the Soviet Navy's inventory on 16 February 1945, reflecting pragmatic resource prioritization in the war's aftermath over preservation for sentimental or experimental value. It was subsequently broken up for scrap in the mid-1950s, approximately according to some accounts, with hull components and fittings repurposed for mockups or early development, though precise allocation records remain limited. No significant incidents marked its disposal, underscoring the Soviet emphasis on material recovery amid rapid fleet modernization.
