(RAF Photo, 1942)(Source Harold A Skaarup Web Page)A Royal Air Force Handley Page Halifax Mk. II Series I (Serial No. W7676), coded TL-P, of No. 35 Squadron, RAF, based at Linton-on-Ouse, Yorkshire in the UK, being piloted by Flight Lieutenant Reginald Lane, (later Lieutenant-General, RCAF), over the English countryside. Flt Lt Lane and his crew flew twelve operations in W7676, which failed to return from a raid on Nuremberg on the night of 28/29 August 1942, when it was being flown by Flt Sgt D. John and crew.
The Handley Page Halifax is a British Royal Air Force (RAF) four-engined heavy bomber of the Second World War. It was developed by Handley Page to the same specification as the contemporary twin-engine Avro Manchester.
The Halifax has its origins in the twin-engine HP56 proposal of the late 1930s, produced in response to the British Air Ministry's Specification P.13/36 for a capable medium bomber for "world-wide use." The HP56 was ordered as a backup to the Avro 679, both aircraft being designed to use the underperforming Rolls-Royce Vulture engine. The Handley Page design was altered at the Ministry to a four-engine arrangement powered by the Rolls-Royce Merlin engine; the rival Avro 679 was produced as the twin-engine Avro Manchester which, while regarded as unsuccessful mainly due to the Vulture engine, was a direct predecessor of the famed Avro Lancaster. Both the Lancaster and the Halifax would emerge as capable four-engined strategic bombers, thousands of which would be built and operated by the RAF and several other services during the War.
On 25 October 1939, the Halifax performed its maiden flight, and it entered service with the RAF on 13 November 1940. It quickly became a major component of Bomber Command, performing routine strategic bombing missions against the Axis Powers, many of them at night. Arthur Harris, the Air Officer Commanding-in-Chief of Bomber Command, described the Halifax as inferior to the rival Lancaster (in part due to its smaller payload) though this opinion was not shared by many of the crews that flew it, particularly for the MkIII variant. Nevertheless, production of the Halifax continued until April 1945. During their service with Bomber Command, Halifaxes flew a total of 82,773 operations and dropped 224,207 tons of bombs, while 1,833 aircraft were lost. The Halifax was also flown in large numbers by other Allied and Commonwealth nations, such as the Royal Canadian Air Force (RCAF), Royal Australian Air Force (RAAF), Free French Air Force and Polish forces.Wikipedia
History of the Squadron during World War II (Aircraft: Wellington III, X, Halifax III, Lancaster X)
425 Squadron was formed at Dishforth, Yorkshire, UK on June 25, 1942 as the RCAF's twenty-second squadron, and fifth bomber squadron, to be formed overseas in WWII. At the time it was part of No 4 Group, RAF Bomber Command. It was unique in being designated "French-Canadian" and every effort was made to find French Canadian airmen elsewhere in Bomber Command who could be transferred to the squadron. It became operational in October, 1942, flying Wellington Mk III aircraft with the squadron code letters KW. It transferred to No 6 (RCAF) Group, Bomber Command when that was formed on January 1, 1943, although remaining at Dishforth. In March, the squadron re-equipped with Wellington X's and from June to October operated from bases in Tunisia (Kairouan/Zina and Hani East airfields) in support of the Allied invasions of Sicily and Italy. In November 1943 the squadron returned briefly to Dishforth and re-equipped with Halifax III aircraft before moving to Tholthorpe, Yorkshire in December, as part of No 62 (RCAF) Base of 6 Group. It remained at Tholthorpe until the end of the war in Europe. In May and June of 1945 it re-equipped with Lancaster X aircraft, in preparation for joining the Tiger Force for attacks on Japan. The surrender of Japan caused the disbandment of the Squadron at Debert, Nova Scotia , on September 5, 1945.
Overall, the squadron flew 328 missions, involving 3694 sorties, in the course of which 9152 tons of bombs were dropped and 55 aircraft were lost. Squadron personnel gained 2 MBE's, 63 DFC's and 4 Bars to DFC, 2 GM's, 18 DFM's, 1 DFC(USA), and 4 MiD's. 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, Normandy 1944, Rhine, Biscay 1943-44, Sicily 1943, Italy 1943, Salerno.

History of the Squadron Post-WWII (Aircraft: Canuck, Voodoo, Hornet)
The squadron was re-formed as an All-Weather (Fighter) unit at St Hubert (Montreal), Quebec on 1 October 1954. It flew CF-100 Canuck aircraft on North American air defence. Selected as one of five units to be re-equipped with CF-101 (Voodoo) aircraft, it was deactivated on 1 May 1961 pending delivery of the aircraft. Reactivated at Namao (Edmonton), Alberta on 15 October 1961, the squadron initially received the trainer version of the CF-101 and served as a training unit to convert the remaining four squadrons to this aircraft. It afterwards moved to Bagotville, Quebec, in July 1962, and was declared operational on 1 October when No. 3 All-Weather (Fighter) Operational Training Unit assumed responsibility for all future CF-101 training. On 1 February 1968 the squadron was integrated into the Canadian Armed Forces. From 1982, the Canadian Forces started to acquire CF-18 Hornets; 425 Sqn received them in 1985. In 2005, 433 Squadron was merged into 425 Squadron. 425 Tactical Fighter Squadron is an integral part of NORAD and of the North Atlantic Treaty Organization (NATO). In peacetime, the squadron's fighters provide continuous surveillance of the East Coast of Canada. In addition, it must be ready for rapid deployment anywhere in the world in support of NATO or contingency operations.Wikipedia, Kostenuk & Griffin, and www.canada.ca/en/air-force/corporate/squadrons/425-squadron.html
The Halifax was the most common heavy bomber employed by Canadians in WW2 -- over 70% of Canadain bomber crews were asigned to the Halifax Bomber. Canada's highest losses of airmen in Halifaxs:

Aircraft Origin
The origins of the Halifax lay in the twin-engine H.P.56 proposal of the late 1930s, produced in response to the British Air Ministry's Specification P.13/36 for a medium bomber for 'world-wide use'. Handley Page initially envisioned a design using of two Rolls-Royce Vulture X-24 engines, but as the airframe design developed and the Vulture's shortcomings became more apparent, the twin-engine H.P.56 evolved into the larger and more capable H.P.57 Halifax powered by four Rolls-Royce Merlin engines. The first flight took place at RAF Bicester on 25 October 1939, the aircraft entering RAF service just over a year later on 13 November 1940.
Ventral Turret
In service it quickly became apparent that the Boulton Paul Type K ventral turret as fitted to early Mk.I aircraft with its twin 0.303-inch calibre machine guns was next to useless, and the turret was replaced on later Mk.Is and early H.P.59 Mk.IIs by two beam gun positions each with twin Vickers Type K 0.303-inch machine guns. In turn the beam guns were also found to be redundant and were soon discontinued.
Rudder Overbalance
However, much more serious deficiencies became apparent following the introduction of the heavier Halifax Mk.II and H.P.63 Mk.V with its Dowty undercarriage and hydraulic system. In addition to poor overall performance, the number of aircraft lost in mysterious circumstances began to rise alarmingly. Following a protracted investigation, the cause was eventually traced to irrecoverable loss of control due to rudder overbalance and was cured by the introduction of the distinctive large rectangular D-Type fins and rudders.
Performance Improvements
Loss of performance in the Mk.II & V was addressed by a number of means including replacement of the front turret by a metal and later Perspex one-piece nose, and replacement of the bulbous drag-inducing Boulton Paul two gun Type C mid-upper turret with the lower profile four gun Type A turret. Improved engine cowlings, more powerful Merlin engines and a general airframe clean-up also helped to somewhat restore the Mk.II and V's performance.
Bristol Hercules Engines
A further improvement of the Merlin-powered Halifax known as the Mk.IV was planned but never built, the design featuring increased wingspan and even more powerful Merlins in completely redesigned and repositioned nacelles. However, a study of the advantages of the sleeve valve 14-cylinder Bristol Hercules radial engine convinced Handley Page to discontinue Merlin Halifax development and instead introduce the Hercules-powered H.P.61 Mk.III. Initially built with 98 ft 10 in wingspan, the Mk.III soon received the still-born Mk.IVs 104 ft 2 in wings, the new mark proving to be the turning point in the Halifax's fortunes.
Later in the war, the Halifax H.P.63 Mk.VI with more powerful fuel-injected Hercules 100 series engines, improved flying controls and systems proved to be the pinnacle of wartime Halifax development, the mark outperforming the Lancaster in some respects. Unfortunately, the Hercules 100 wasn't available in sufficient quantities, and so the Mk.VI airframe was also built with lower powered Hercules XVIs as the Halifax H.P.63 Mk.VII.
.5-inch (50 calibre) Machine Guns
The advantages of the 0.5-inch calibre machine gun over the 0.303-inch calibre were well known and following a protracted turret development programme, some Mk.VII & IX aircraft were fitted with Boulton Paul Type D rear turrets with twin 0.5-inch guns. The final bomber variant was the H.P.71 Mk.IX. Like the earlier variants the IX could also be used for glider towing and paratrooping, and for the latter task the Mk.IX featured an elongated and repositioned paratroop exit aperture.

Series Designations
In addition to the basic mark number the Halifax Mk.I, II & V also had a series number eg. series 1, series 1a, series 2. The series number is not included in our database because it is not easily or accurately determined.
Mk.II & V
The basic series number of all the rest of the Mk.IIs & Vs was Series 1. Some early production airframes were built as straight Series 1s and later modified, and some later production airframes were built with one or both of the key suffix-changing modifications already incorporated. Regardless of whether the change/s occurred during or post-manufacture, a suffix was supposed to be added to the series number when the following changes occurred:
Replacement of the front turret with the one-piece metal fairing (Mod.398 aka Tollerton nose, Tempsford nose or Z-fairing) - this added the suffix (Special) after the series number i.e. Series 1 (Special).
Installation of Merlin 22 engines and Morris radiators along with modified engine cowlings - this added the letter 'A' to the series number i.e. Series 1A.
However
Some late production Mk.II Series 1 (Specials) were fitted with Morris radiators and Merlin 22s but retained the designation Series 1 (Special).
Some Series 1 aircraft were fitted with the previous type of Gallay radiators but were designated as Series 1A.
Aircraft with the Mod.452 Perspex nose but without Morris radiators/Merlin 22s were not Series 1A, and the actual designation of such aircraft i.e. Series 1 or Series 1 (Special) is unknown.
NOTE - In period as now, it was widely but incorrectly believed that an aircraft became a 1A when the one-piece Perspex nose was added, but an airframe became a Series IA only when Merlin 22 & Morris radiators were installed - addition of the one-piece Perspex nose (and the large D-Type fins) made no change to the series suffix.
To add to the confusion production records are not only incomplete but sadly in a great many instances they also do not record whether a particular airframe was a Series 1, Series 1 (Special) or Series 1A. And if that wasn't enough many aircraft were field modified and the modification/s were not recorded, which of course means that many airframes could and did start life without a series suffix and gain one later when the engine or nose type changed, yet the records don't reflect the changes!
The bottom line is that unfortunately it's impossible to list the series/engine sub-model breakdowns of the Mk.II & V Series 1 aoircraft. Really the best that can be said is that early Mk.IIs and Vs had Merlin XXs and the later ones had Merlin 22s.
Meteorological Variant
Predicting the weather was a significant problem. The weather generally flows west to east in the northern hemisphere, so ascertaining the weather as far out as possible in the Atlantic Ocean gave indications of future weather events in Britain and on the continent.
The main variant was the MET V which looked very similar to a Coastal Command GR Mk.V. The aircraft themselves were fitted with very sensitive air temperature and humidity measuring equipment, plus radio altimeters to allow the crews to fly very accurately at selected altitudes, and they also carried an extra crew member who recorded the weather data. Towards the end of the war the Halifax MET V was supplemented by the MET III and VI.
From airfields located on the west coast of the UK including Tiree on the Isle of Skye, Stornoway on the Isle of Lewis, Brawdy in Wales and Chivenor in Devon the aircraft regularly flew extremely long duration meteorological reconnaissance flights over the Atlantic.
The weather forecasts used for D-Day planning were partly based on data provided by the MET Halifax squadrons.
