The Czechoslovak Air Force (Československé letectvo) or the Czechoslovak Army Air Force (Československé vojenské letectvo) was the air force branch of the Czechoslovak Army formed in October 1918. The armed forces of Czechoslovakia ceased to exist on 31 December 1992. By the end of the year, all aircraft of the Czechoslovak Air Force were divided between the Czech Air Force and the Slovak Air Force.

Organization

On 30 October 1918, the establishment of Aviation Corps (Letecký sbor) marked the beginning of the Czechoslovak Air Force.

Under the First Republic, the air force was an integral service of the Czechoslovak army. During peacetime, the army aviation was a subordinate agency of the Ministry of National Defence within its 3rd Department of Aviation (III. odbor (letecký) Ministerstva národní obrany) under the command of divisional general Jaroslav Fajfr (as of October 1938). It was anticipated that individual squadrons and flights would be attached to various field corps and divisions in case of war with Germany.

After the liberation of Czechoslovakia in 1945, the air force was once again organized as an integral part of the army within following ministerial departments: 1945–1950: Air Force Command of the Main Staff (Velitelství letectva hlavního štábu) 1950–1957: Air Force Command (Velitelství letectva)

In mid-1950s, following the example of Soviet Air Defence Forces, the State Air Defence (Protivzdušná obrana státu, PVOS) was formed alongside the Air Force. 1957–1966: Air Force and State Air Defence Command (Velitelství letectva a protivzdušné obrany státu) 1966–1969: Main Department of Air Force and State Air Defence (Hlavní správa letectva a vojsk protivzdušné obrany státu) 1969–1976: Department of Air Force and State Air Defence (Správa letectva a vojsk protivzdušné obrany státu)

In 1976, the State Air Defence formed its own command (1976–1990). 1976–1990: Air Force Command (Velitelství letectva) – see also Air Forces Command structure in 1989

In May 1990, the State Air Defence (PVOS), Air Defence of Ground Forces and Frontline Aviation were merged to form an integrated branch of the armed forces – the Czechoslovak Air Force and Air Defence. 1990–1991: Air Force and State Air Defence Command (Velitelství letectva a protivzdušné obrany státu) 1991–1992: Air Force and Air Defence Command (Velitelství letectva a protivzdušné obrany)

History Under the First Republic 1918–1938

When the First Czechoslovak Republic was founded in October 1918 it was landlocked and surrounded by potentially hostile neighbours. Its government realised the need for an air force, and quickly founded one with the motto "Our sea is in the air".

From Austria-Hungary the new republic inherited only three military airfields and a handful of Hansa-Brandenburg aircraft. In the First World War few Czechs or Slovaks had served in the Imperial and Royal Aviation Troops or naval air corps, or in exile in the French Air Force or Imperial Russian Air Service.

Much of Austria-Hungary's manufacturing companies were Czech, therefore Czechoslovakia could quickly develop an aircraft industry. At first it tended to build foreign designs of aircraft and aero engines under license. As the industry developed it designed more aircraft and engines of its own. Czechoslovak aircraft builders included Aero, Avia, Beneš-Mráz, Letov, Praga, Tatra and Zlín. Engine makers included ČKD, Walter and Škoda.

Aero (Aero továrna letadel) was in the Vysočany quarter of Prague. Its mixed construction (wood, metal, and fabric covering) and all-metal aircraft were competitive in the early 1930s, but by 1938, only its MB.200 (a licensed Bloch design) was not totally obsolete.

Avia (Avia akciová společnost pro průmysl letecký Škoda), a branch of the enormous Škoda Works (Škodovy závody) heavy machinery and military industrial enterprise, was different. Founded in 1919 in a former sugar refinery in the eastern Prague suburbs of Letňany and Čakovice, Avia made entire aeroplanes. Many of its engines were licensed Hispano-Suiza designs. It build the standard Czechoslovak fighter aircraft of the late 1930s, the B-534, of which a total 568 were built. The B-534 and its derivatives were among the last biplane fighters in operational use.

The state-controlled Letov factory (Vojenská továrna na letadla Letov) was also in Letňany, where in the late 1930s it employed about 1,200 people. It built the Š-28 reconnaissance and army co-operation biplane, of which more than 470 were made. The entire airframe was welded together, not bolted or riveted. The Letov factory was the only Czechoslovak plant that made metal propellers.

By the late 1930s Czechoslovakia's bomber aircraft were obsolescent and the speed with which Nazi Germany was becoming a threat did not give Czechoslovak manufacturers enough time to develop a new bomber of their own. So in 1937 the government bought Tupolev SB twin-engined medium bombers from the Soviet Union, plus a license to build more in Czechoslovakia as the Avia B-71. 60 Soviet-built SB bombers were delivered in April and May 1938. This was followed by Avia and Aero building 101 of the B-71 version.

The training of air force recruits had developed from a course of several months in the 1920s to two years by the late 1930s. In 1936 Reichsmarschall Hermann Göring wrote "The Czechoslovak Air Force must be considered as one of the leading air forces as regards personnel, and, considering its limited financial possibilities, more than satisfactory with regard to material and equipment".

Crisis and occupation 1938–1939 As the Sudeten crisis with Germany worsened, the Czechoslovak Army and Air Force partly mobilised on 21 May 1938 and fully mobilised on 23 September. The air force had more than 100 airfields and 1,300 aeroplanes, of which 650 were front-line aircraft. But on 29 September the United Kingdom and France agreed to let Germany annex the Sudetenland, which German forces then did without Czechoslovak armed forces being allowed to resist.

The Munich Agreement was followed on 2 November 1938 by the First Vienna Award, in which Germany and Fascist Italy allowed Hungary to annex southern Slovakia. Then on 15 March 1939 Germany occupied Czechoslovakia, created the Protectorate of Bohemia and Moravia rump state and allowed what remained of Slovakia to become the Slovak Republic. Germany allowed Slovakia to keep a small army and air force, but it ordered the puppet government of Bohemia and Moravia to dissolve its armed forces.

The Luftwaffe confiscated all Czechoslovak Air Force aircraft. All Czechoslovak aircraft factories were converted to produce German aircraft and engines.

The Luftwaffe tried to recruit demobilised Czechoslovak airmen to non-combat roles such as ferry flights and meteorological flights, but without success. It also confiscated Czechoslovak aircraft and tried to get Czechoslovak airmen to fly them to Germany. But of seven Czechoslovak pilots who took off from Hradec Králové airfield in Bohemia, none reached Germany. Three flew to Poland, two reached the USSR and the other two crash-landed their aircraft, without injuring themselves but rendering their aircraft beyond economic repair. Thereafter Germany gave up trying to use Czechoslovak airmen.

Emigration was strictly controlled and former air force personnel were not allowed to leave the country. But many Czechoslovak airmen got themselves smuggled into Poland. Of these a few joined the Polish Air Force but most continued to France.

Second World War 1939–1945

Czechoslovak pilots who joined the Polish Air Force went into action in September 1939 when Germany invaded Poland. Many fought with distinction and 55 were decorated. Josef František was among those awarded Poland's highest military decoration, the Virtuti Militari. After the USSR joined the invasion of Poland its forces captures some Czechoslovak airmen. Others escaped as Poland fell, first reaching Romania and then going via the Balkans and Syria or Lebanon to join their compatriots who had already reached France.

At first France insisted that all Czechoslovak airmen join the Foreign Legion. Only after France had declared war on Germany did it agree with the Czechoslovak National Committee in Paris to let the men transfer to the French Air Force and restore their ranks. They needed to be re-trained to fly French aircraft, but some completed their training in time to fight in the Battle of France in May and June 1940. Of these, seven were awarded France's highest military decoration, the Légion d'honneur, and five received the Médaille militaire. 70 Czechoslovak airmen, including Josef František and Karel Kuttelwascher, were awarded the Croix de Guerre.

RAF Volunteer Reserve 1940–1945

After France capitulated to Germany on 22 June 1940, many Czechoslovak airmen escaped via either France's Atlantic or Mediterranean coasts or from French North Africa. They reached the United Kingdom, where Brigadier General Karel Janoušek quickly secured an agreement with the UK War Department for them to join the Royal Air Force Volunteer Reserve (RAFVR). On 12 July 1940 an Inspectorate of the Czechoslovak Air Force was established, with Janoušek as Inspector-General with the RAF rank of Air Commodore.

A Czechoslovak depôt was created at RAF Cosford in Shropshire. The RAF quickly created new squadrons formed of Czechoslovak pilots. The first fighter unit was No. 310 Squadron RAF, which was formed on 10 July 1940 and immediately joined in the Battle of Britain. By the end of July a bomber unit, No. 311 Squadron RAF, had been added. Further Czechoslovak fighter units followed: 312 Squadron by August 1940 and 313 Squadron in May 1941.

Czechoslovaks quickly adapted to the structure, tactics and aircraft types of the RAF. Air Chief Marshal Hugh Dowding, who led RAF Fighter Command in the Battle of Britain, later recalled:

I must confess that I had been a little doubtful of the effect which their experience in their own countries and in France might have had upon the Polish and Czech pilots, but my doubts were soon laid to rest, because all three squadrons swung in the fight with a dash and enthusiasm which is beyond praise. They were inspired by a burning hatred for the Germans which made them very deadly opponents.

From 1940 until 1942, 311 Squadron was part of No. 3 Group, Bomber Command. The Group commander said 311 "put up a wonderful show" and had "the finest navigators in Bomber Command".

A preponderance of air force personnel who escaped from occupied Czechoslovakia were aircrew. The RAF had a shortage of Czechoslovak ground crew, so the new squadrons continued to rely in part on ground crew from the UK and other nationalities. And numerous Czechoslovak airmen were posted to more than 60 other RAF units, including 11 front-line squadrons.

Enough Czechoslovaks were posted to No. 68 Squadron RAF to form an entire flight. No. 68 Squadron even adopted a Czech motto, Vždy připraven ("Always ready"). Czech fighter ace Josef František, acclaimed by one wartime author as "the greatest of all Czechoslovak pilots, perhaps one of the greatest fighters of all time", served in the Battle of Britain in No. 303 Polish Fighter Squadron. Karel Kuttelwascher, a night fighter ace nicknamed the "Night Reaper", served in No. 1 Squadron.

Soviet Air Force Other Czech and Slovak pilots fought against Germany under Soviet command. The Air and Air Defence Forces of the postwar Czechoslovak People's Army celebrated 17 September 1944 as the birth date of their force. On that date, a fighter regiment, manned by Czechoslovak personnel, was formed in the Soviet Union. It grew into the 1st Czechoslovak Mixed Air Division which fought on the Eastern Front.
