THE ROYAL AIR FORCE IN THE 1930S

 
     
 

PART ONE : ARMSTRONG WHITWORTH TO GLOSTER

 
     
  The two decades between the signing of the Treaty of Versailles in 1919 and the outbreak of the Second World War in 1939 have been described as the locust years of the Royal Air Force (RAF). With aircraft becoming ever more complex and expensive, successive British governments were unwilling to spend scarce resources on re-armament if immediate benefits - such as the cost-effective policing of the more rugged and volatile parts of the British Empire - could not be accrued.

This outlook was to be more firmly entrenched after the Wall Street Crash of 1929 but - during the resultant Depression - the rise of fascism in Europe made the modernisation of Britain's armed forces imperative.

This article uses photographs taken by Warrant Officer James Marshall - the father of Gloucestershire Message Board contributor Valerie Wiersema who kindly donated them - to give an impression of the Royal Air Force during these impoverished yet turbulent times.

The aircraft are arranged in alphabetical order by manufacturer and type and the pictures in chronological order wherever possible.

  ARMSTRONG WHITWORTH ATLAS  
     
  Designed from the outset as an Army co-operation aircraft, the two seat Atlas entered RAF service in early 1927 and fully equipped 26 Squadron ( later to fly the Bristol Belvedere helicopter ) by November that year. In the years 1927 - 30, the metal framed but mainly fabric covered biplanes also equipped five other squadrons. A total of 478 Atlases - able to carry wireless, wireless and message pick-up equipment - were produced, remaining in RAF service until 1933 as a training aircraft. At least 16 Atlases were transferred to the Royal Canadian Air Force (RCAF), several of which continued in service until 1941.

  ARMSTRONG WHITWORTH SISKIN III AND IIIA  
     
  The Siskin III fighter was based on the Siddeley Siskin SR2 of 1918 and the first of 63 Siskin IIIA airframes - 47 two seat and 16 single seat variants - were introduced to RAF service in May 1924. Siskin III J7001 was converted to the prototype Siskin IIIA - powered by the stronger Jaguar IVC engine. The first Siskin IIIAs equipped 111 Squadron - later to find fame with Hawker Hunters and English Electric Lightnings - in 1926 and ten other squadrons eventually followed suit. Almost 350 Siskin IIIAs were eventually built - mostly for the RAF, which began to phase them out of front line service in 1933. However, a batch of RCAF Siskin IIIAs continued in use until 1939. Highly aerobatic and pleasant to fly, the angular Siskin was also the RAF's first all-metal structure fighter to achieve production status.

  AVRO AVIAN  
     
  The prototype Avro Avian flew in the summer of 1926, and for much of its production life remained an all-wood aeroplane with no metal tubing in the fuselage. While it was designed to appeal to the growing civilian market for a light sports plane to rival the De Havilland Moth, the Avian found its way to the far reaches of the globe. They were used not only by private individuals, but also by many flying clubs and military flight training organizations. In addition to being made in England, Avians were manufactured under license in Canada and the United States.

In 1926 two pre-production Type 594 Avian Mk Is were followed by nine Mk. IIs and in mid-1927 the Mk. III appeared, of which 33 were built with the 84hp Cirrus II engine, and 58 as the model Mk. IIIA using the 94hp Cirrus III engine. The last all wood Avian was the Mk. IV, still with the Cirrus III engine. One of the principal improvements in the Mk. IV was a strengthening of the landing gear and wing root area and from 1929 on, the steel tube fuselage was introduced and the Type 616 Avian Mk. IVM powered by the Cirrus III and larger engines was born. It is the Avian MK. IVM that was also built in the U.S. and Canada in small numbers.

Bert Hinkler - Avro test pilot from 1920 to 1927 - made many record setting flights in his own Avian, but he is best known for one in particular. In 1928, he flew solo in his ADC Cirrus Mk. II engined Avian - the first ever built - from Lympne in Kent, England to Australia. He left London on 7 February spanning Europe, the Middle East, the Indian sub-continent, and Asia, finally arriving in Darwin, Australia 16 days later. The flight covered 11,450 miles in 129 flying hours with an average speed of 82.5 m.p.h. For the Australian flight modified wings were fitted giving increased cruising speed. A special 46 gallon tank was fitted in the front cockpit making a total of 66 gallons. A special undercarriage of Bert Hinklers own design was also fitted.

Another famous Avian pilot was Beryl Markham whose book, West with the Night, chronicles her experiences in Africa and her many hours of flight in her trusty Avro Avian. She became a celebrity in her own right when she piloted her blue and silver Avian from Nairobi to London and back, in 1932, with nothing but a map and a compass.

The most famous pilot and the most famous Avro Avian, at least for those in the United States, are Amelia Earhart and her Avian, 7083, although the most tragic remains Bill Lancaster and Southern Cross Minor.

Bill Lancaster had served as a pilot officer in the Australian Flying Corps in World War One and in 1927 made one of the first flights from England to Australia in his Avro Avian Red Rose, accompanied by Jessie "Chubby" Miller, a wealthy journalist who helped to finance the flight.  Tried and acquitted of murdering Miller's lover in Miami in 1932, Lancaster found himself short of funds in London and decided to recapture the headlines with a record breaking flight from London to South Africa.  To do this he bought another Avian, Southern Cross Minor, which could only better the existing fastest timing if Lancaster flew 20 hours a day.

On the evening of 12 April 1933 Lancaster left Reggane in central Algeria with the aim of flying 750 miles south across the Sahara at night.  Even with extra fuel tanks this was at the edge of the Avian's range and Lancaster had not slept for 30 hours.  Within an hour of departure the engine seized up and Lancaster was forced to land 60 miles north of both his intended route and any land or air based search parties.  The diary he kept while waiting to be rescued showed that he lived until the morning of the eighth day after the crash but his body and the crashed Avian were not found until 29 years later in 1962 by a French long-range desert patrol.  Bill Lancaster's body was then buried in Reggane and the remains of his aircraft are stored out of public view at the Museum of Queensland in Brisbane, Australia.

AVRO 504N LYNX

 
  The Lynx was the final variant of the rotary engined Avro 504 trainer which first flew in September 1913 and was in turn developed from the Avro 500 trainer biplane of 1912. The 504N Lynx served with the Royal Air Force from 1927 to 1933 before being replaced by the Avro Tutor. Six 504N Lynxes from the Central Flying School at Wittering pioneered blind instrument flying in 1931

  AVRO TUTOR  
     
  The Avro Tutor entered RAF service in 1930 as the Avro 621 Trainer with an uncowled Mongoose engine. It was adopted as the standard RAF trainer, replacing the Avro 504N Lynx from 1932. A total of 795 Tutors were built, 394 being deliverd to the RAF. Fully aerobatic and easy to fly, the Tutor continued the pattern of instrument flying technique pioneered by its predecessor. Its aerobatic qualities were demonstrated by Tutors of the Central Flying School at each annual Hendon Air Display. The Tutor remained in RAF service until 1939. A batch of 14 Tutors was modified to accept twin floats to become Sea Tutors and these served mainly at RAF Calshot as trainers for future maritime RAF crews. Today one Avro Tutor - K3215 / G-AHSA - still flies with the Shuttleworth Collection at Old Warden, Bedfordshire.

  BLACKBURN BAFFIN  
     
  The prototype Blackburn Baffin two seat torpedo bomber was originally known as the Blackburn Ripon V and began replacing the earlier Ripons in Fleet Air Arm service from January 1934. Only 29 Baffins were produced as new although at least 68 Ripons were upgraded to Baffin standard with a Bristol Pegasus air cooled radial engine. However, as Baffin performance was only marginally better than that of the Ripon, it was in turn replaced in front line service from 1936 and only equipped three Fleet Air Arm squadrons. In 1937 29 Baffins were sold to New Zealand where they formed three Territorial squadrons for coastal defence until 1941.

  BLACKBURN DART  
     
  The single seat Blackburn Dart was developed from the Blackburn Swift torpedo bomber of 1920. the prototype Dart was first flown in October 1921 and deliveries of the first of 117 production machines began in March 1922. Despite its size, the Dart handled well and remained in service for 10 years aboard Home and Mediterranean Fleet aircraft carriers before replacement by Blackburn Ripons and Baffins. In July 1926 Darts helped pioneer night deck landing techniques.

  BOULTON & PAUL OVERSTRAND  
     
  A fully aerobatic and improved replacement for the Boulton & Paul Sidestrand day bomber, the Overstrand was the first RAF medium bomber to feature a totally enclosed power operated ( pneumatic ) gun turret. First flown in 1933, Overstrands superceded Sidestrands in 101 Squadron from December 1934 - prompting the unit's official badge of a castle with turrets. This was to be the only complete RAF Overstrand squadron although four of the new machines were briefly allocated to 144 Squadron. Overstrands - crewed by three to five airmen - continued in front line use until 1937 and in secondary roles until 1941.

  BOULTON & PAUL SIDESTRAND  
     
  The Sidestrand was the RAF's first twin engined day bomber since the De Havilland 10 of 1918 and first flew in prototype form in 1926. Highly manoeverable and a rock-steady gun and bomb platform, the Sidestrand exclusively equipped 101 Squadron from April 1928 to December 1934 when the unit became the sole complete unit of its successor, the Overstrand. 18 Boulton & Paul Sidestrands were built, several of which were upgraded to Overstrand standard with more powerful engines and power operated front turret.

  BRISTOL BULLDOG  
     
  Developed from a private venture prototype of 1927, the Bulldog entered squadron service intitally as the Mark II in May 1929. Its superb aerobatic qualities, strength of construction and, for its day, excellent performance envelope endeared it to most pilots, and the Bulldog eventually equipped a total of 10 RAF fighter squadrons. At least 87 two seat trainer versions were later produced and the last 17 Bulldogs built were sold to Finland in 1934. These aircraft later saw active service in the 1939-40 Winter War against the USSR. Bristol Bulldogs finally left RAF service in 1937.

  BRISTOL F2B FIGHTER  
     
  The two seat Bristol F2A Fighter first flew in late 1916 and joined 48 Squadron Royal Flying Corps in France in March 1917. Early combat experience led within months to the modified F2B variant, which equipped units in France, Italy, Palestine and the UK and the F2B stayed with the RAF until early 1932. 3101 F2Bs were produced during the First World War with further small batches being erected during the 1920s. The only flyable example left today is former 208 Squadron "Brisfit" D8096 of the Shuttleworth Collection at Old Warden in Bedfordshire.

  DE HAVILLAND MOTH  
     
  The de Havilland Moth went on to become one of the most famous light aircraft types in history, evolving into the Queen Bee target drone seen below, Tiger Moth, multi seat cabin Fox Moth, the monoplane Puss Moth and post World War II Chipmunk trainer. One important recognition feature is the engine, conventionally mounted with cylinder heads at the top. Later family members would have their engines inverted to give the pilot a better view ahead.

  FAIREY IIIF  
     
  Developed from the 1924 vintage Fairey IIID, the IIIF entered RAF service in 1927 and Fleet Air Arm service in 1928. Indeed, the three seat naval reconnaissance IIIF became the most widely used FAA aircraft of the inter war years. Although superceded by 1933, at least three became Fairey Queen radio controlled gunnery targets and others survived in secondary roles until 1941.

  FAIREY HENDON  
     
  Origianally known as the Fairey Night Bomber, the Hendon only received its final name in October 1934, almost three years after the prototype had first flown in Novemberber 1931. However, the first cantilever monoplane heavy bomber to be built in Britain only entered RAF service in November 1936 and then to equip only 38 Squadron with just 14 aircraft. These were replaced by Vickers Wellingtons from November 1938.

  GLOSTER AS 31 SURVEY  
     
  The Gloster Aircraft Company designed this replacement for the single engined DH9 in the imperial survey and mapping role from another de Havilland Aircraft Limited concept, the DH67A. de Havilland gave this project to Gloster as their own works were already busy with the DH66 airliner and Moth series of biplanes. Indeed, the DH67A had started out as a scaled down DH66 but the three engine and fin configuration was later amended to a single tailfin and two engines. Other specialised features were the mainwheel mudguards and fuselage built in three parts. This was to allow an AS31 downed in hostile territory to be quickly dismantled for ground evacuation. it was also possible for a Williamson Eagle camera to be lowered through a purpose built aperture in the lower fuselage to allow unrestricted photography.

The first example - registered G-AADO - first flew from Hucclecote in June 1929 and was used by the Aircraft Operating Company to survey 63 000 square miles of Northern Rhodesia ( now Zambia ) from 1931 - 1935. G-AADO later became aircraft 250 of the Royal South African Air Force and was based at Zwartkop aerodrome, Valhalla, on photographic duties until 1942

The second machine - K-2602 - was exhibited at the International Aero Show at Olympia in July 1929 and was flown by the Royal Aircraft Establishment at Farnborough for wireless telegraphy trials until struck off charge in 1937.

  GLOSTER GAUNTLET  
     
  Developed from the Gloster SS18 of 1927, the prototype Gauntlet first flew in 1933 and displayed a 40 mph advantage over the Bristol Bulldog. It was to be the last RAF fighter with an open cockpit but the first all-metal Folland designed Gloster fighter to enter service. Gauntlets entered squadron service in 1935 and soon found fame for their aerobatic qualities. Following the takeover of Glosters by Hawker Aircraft in 1934, the Mark II Gauntlet displayed more of the latter's design philosophy but was considered obsolete by 1939. However, 25 examples were sent to Finland in 1940 to help repel the Russian invaders. In November 1936 three 32 Squadron Gauntlets also became the first fighter aircraft to be directed to intercept a target by radar.

  Further research has now revealed that Gloster Gauntlet K4083 was delivered new to 19 Squadron at Duxford on 25 January 1935 but only flew in the unit's blue and white chequer markings until 20 April 1937 when it was damaged beyond economic repair in a forced landing. The biplane's serial number also appears in the log book of Jeffrey Quill, best known for his test pilot work on the Supermarine Spitfire but who also flew with the Duxford Meterological Flight, formed with a number of aircraft including Gauntlets during 1934/35. When this Meterological Flight moved to Mildenhall in the Autumn of 1936 it became an all-Gauntlet unit while a similar Meterological Flight formed at Aldergrove in Ulster in January 1937 also converted wholly to Gloster Gauntlets later in that year. Gauntlets were replaced by Gloster Gladiators in the meterological role late in 1939 and continued flying these sorties until early 1945.
