Avro Lancaster Mk. X RCAF Serial FM 213 Canadian Warplane Heritage Museum
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era.
The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a capable medium bomber for "world-wide use". Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one version, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic bombing offensive over Europe gathered momentum, it was the main aircraft for the night-time bombing campaigns that followed. As increasing numbers of the type were produced, it became the principal heavy bomber used by the RAF, the Royal Canadian Air Force (RCAF) and squadrons from other Commonwealth and European countries serving within the RAF, overshadowing the Halifax and Stirling.

History of the Squadron during World War II (Aircraft: Wellington III, X, Halifax III, Lancaster I, III)
424 Squadron was the sixth RCAF bomber squadron to be formed overseas in WWII, at Topcliffe, Yorkshire, UK on October 15, 1942, originally as part of No 4 Group of RAF Bomber Command. It remained at Topcliffe when it was transferred to the newly-formed 6 (RCAF) Group on January 1, 1943. It moved to Leeming, Yorkshire , and then Dalton, Yorkshire , flying Vickers Wellington Mk III and X aircraft before being dispatched on June 22, 1943 to No 331 (RCAF) Wing of No 205 Group in Tunisia (Kairouan/Zina and Hani East airfields), from where it flew in support of the invasions of Sicily and Italy. It returned by sea to Skipton-on-Swale, Yorkshire in October/November 1943. It re-equipped with Handley Page Halifax Mk III aircraft, which it flew until January 1945, when it re-equipped with Avro Lancaster I and III aircraft. After the termination of hostilities in Europe, the squadron was transferred to No 1 Group, and was employed in operation DODGE, the repatriation of British and Canadian troops from Italy. It was disbanded at Skipton on October 15, 1945, 3 years to the day since its formation.
In the course of hostilities, the squadron flew 3257 sorties for the loss of 52 aircraft. 8776 tons of bombs were dropped. Crew members were awarded 1 DSO, 49 DFC's and 1 Bar to DFC, 1 CGM, 11 DFM's and 1 MiD. Battle Honours were: English Channel and North Sea 1943-45, Baltic 1944-45, Fortress Europe 1943-44, France and Germany 1944-45, Biscay Ports 1943-44, Ruhr 1943-45, Berlin 1944, German Ports 1943-45, Nornamdy 1944, Rhine, Bisacy 1943-44, Sicily 1943, Italy 1943, Salerno.Wikipedia, Kostenuk and Griffin

History of the Squadron Post-WWII (Aircraft: Harvard II, Mustang IV, Silver Star 3, Expeditor, Otter, Griffon, Hercules)
The squadron was re-formed at Mount Hope, Hamilton, Ontario on 15 April 1946, as a light bomber unit. It was redesignated as an auxiliary fighter unit on 1 April 1947. It flew North American Harvard II and Mustang IV aircraft in a fighter role, as well as Canadair Silver Star aircraft until 1 September 1957 when it was then reassigned as a light transport and emergency rescue role and re-equipped with Beechcraft Expeditor and de Havilland Otter aircraft. On 21 October 1961 the unit received its Squadron Standard for 25 years’ service as No. 119 and 424 Squadron. A reduction of the Auxiliary Force resulted in the squadron being disbanded on 1 April 1964. On 8 July 1968, with unification of the Canadian Forces, the squadron was reactivated as 424 Communications and Transport Squadron, operating from CFB Trenton, Ontario . The squadron has flown more than 14 different types of aircraft during its history.
424 (Tiger) Squadron is now a Transport and Rescue Squadron based at 8 Wing Trenton. To fulfil its roles, 424 Squadron operates the CH-146 Griffon helicopter and the CC-130H Hercules. 424 Squadron and 435 Transport and Rescue Squadron provide primary search and rescue response for the Trenton Search and Rescue Region (SRR), the largest in Canada. The Trenton SRR extends from Quebec to the British Columbia/Alberta border, and from the Canada/United States border to the North Pole. The Squadron crews one aircraft of each type on standby response posture in order to respond to distress cases as tasked by Joint Rescue Coordination Centre Trenton.
In addition to providing SAR response through a para-rescue capability, the CC-130H Hercules allows the squadron to conduct its transport role in Canada and around the world. The CH-146 Griffon enables rescues and medical evacuations from locations on land and over water. Both aircraft carry Search and Rescue Technicians onboard in order to provide urgent care to those in need. The members of 424 Squadron provide SAR response to incidents under the federal SAR mandate; all aircraft incidents and all marine incidents in waters under federal jurisdiction. They also support humanitarian missions and other SAR organizations when able. Wikipedia and www.canada.ca/en/air-force/corporate/squadrons/424-squadron.html

Ventral Turrets
ventralturret.jpeg image not found
As originally designed the Lancaster was provided with ventral defence in the form of a Nash and Thompson FN64 turret, which was fitted to some early production aircraft. However, in common with all other periscope sighted ventral turrets, the narrow viewing angle made it almost impossible for gunners to acquire and track targets, and the few turrets which were installed were soon removed from service.

The ventral .50 inch (50 calib) was approved as Lanc Mod.925 during February 1944, and was one of a number of unsuccessful measures taken to counter night fighter attacks from below.
The growth of the Luftwaffe night fighter force was followed by an increase in the in the number of attacks from below, exacerbated from August 1943 onward by the introduction of aircraft equipped with Schrage Musik upward firing 20mm cannon. A number of responses were considered by Bomber Command including a free mounted ventral .50 calibre Browning machine gun, which was approved on the Lancaster as Modification 925 during February 1944.
The modification was very basic, consisting of little more than an enlarged bicycle seat for the gunner and a simple free mounted gun with open sights which fired through the ventral turret/H2S aperture. On aircraft with bulged bomb doors the mounting (often unpainted) was incorporated into the fairing at the rear of the doors.
Non-H2S fitted aircraft were sporadically equipped with the gun from February 1944 onward, although a clear plan for installation appears to have been lacking. The quantity of aircraft which actually had the gun installed is unknown and photos of the mounting with a Browning actually installed are very rare.
Serious problems quickly became apparent, as noted in the following V Group monthly newsletter for April 1944:- "With the gunner strapped in his seat it is difficult to follow the gun round on the beam; it is difficult for the gunner to get his head down behind the sight as it tends to push the oxygen mask upwards on the gunners face; and also considerable vibration is experienced on the sight when the gun is fired."
These problems, plus the gradually more widespread introduction of H2S saw the gun fall out of use quite quickly, although it does appear to have been retained on some aircraft until war's end (most notably in 3 Group).
The quantity of aircraft which actually had the gun installed is unknown and photos of the mounting with a Browning actually installed are very rare.
