Thx lads, there will be some updating of this chapter in near future. Some additional camos mainly. For now we prepare next chapters, number of planes types will steady drop in numbers but there will be some more versions of one plane. Slowly but steady we are every day closer to dreaded '39

Also we work on some other "Wings of" ideas, don't worry we will serve you more and more planes in future. ;)

Time has come for the next chapter of the Polish Wings. Rhade will post the first batch of planes later today, or tomorrow, and before that I'll put here a historical introduction (even though probably nobody is going to read it anyway :P ;) ).

Polish Military Aviation 1921-1939

Supreme Aviation Authorities

In 1921 highest authority of Polish Military Aviation was (since february 1920) Departament Żeglugi Powietrznej Ministerstwa Spraw Wojskowych (DŻP MSWojsk, Department of Aerial Navigation of the Ministry of Military Affairs) headed by gen. Gustaw Macewicz. Because of his deteriorating health, he was replaced in january 1923 by French colonel (later brigadier general) Francois-Leon Leveque. Thanks to quite generous French financial military assistance he was soon able to present ambitious plan of expansion for the air force, which called for 50 squadrons in 10 regiments by 1926 (32 reconaissance, 16 fighter and 2 bomber, with 572 first-line aircraft. Though realization of the plan didn't proceed quite as planned (after year and a half Polish air force had the same number of squadrons - 13 - as when Leveque was appointed to his post), total number and average serviceability of planes was indeed raised and infrastructure was greatly developed.

In august 1924 Leveque was replaced by gen. Włodzimierz Zagórski. He continued his predecessor's policy of reliance on purchases (or license manufacturing) of great number of French aircraft (which were at the moment even too numerous to be used). In 1925 he presented even more ambitious plan, calling for 200 squadrons (66 divisional, 90 army-level and rest at the GHQ disposal) with 2306 aircraft by 1937, although this plan (never formally accepted in full) was too ambitious for economical realities of Poland, it remains very interesting document. On more practical level, by the time he was removed from post (first temporarily in march 1926, and later permamently in may of the same year), Zagórski managed to raise number of operational squadrons to 26 plus 2 maritime (in large part thanks to Leveque's efforts).

Zagórski's succesor, colonel (from 1934 brigadier general) Ludomił Rayski was the longest-serving air force chief of the pre-war Poland (june 1926 - march 1939). He took his post in the aftermath of marshal Józef Piłsudski's coup d'etat of may 1926. Piłsudski, hero of the independence struggle and already head of state 1918-1922, considered aviation merely an auxiliary service, useful mainly for reconaissance, but to little more. That itself wouldn't be so fateful if not his ideas for the organization of military authorities. Until 1926, president was supreme commander of the armed forces, who, in case of war, was to appoint a Commander-in-Chief. Minister of Military Affairs was responsible for all matters of military command and administration and army's preparedness to war. Subordinate to him, the General Staff, services and 10 Dowództwa Okręgow Korpusów (plur. - sing.: Dowództwo Okręgu Korpusu, DOK, Corps District Command).
After May Coup a quite bizarre arrangement was created. On 6 august 1926 a Generalny Inspektorat Sił Zbrojnych (GISZ, General Inspectorate of the Armed Forces) was formed, creating a so-called "dual-track" organization of military authorities. It consisted of:
"War Track" - GISZ with General Staff, which decided of all war and mobilization plans, tactics and development directions for the military. It also consisted of group of officers prepared to take army-level commands in case of war - but who had no staffs (!), and it had no element dealing specifically with aviational matters;
"Peace Track" - MSWojsk (including air force command) responsible for administration, training and procurement, but only in peacetime, and with subordinate DOK's, but reduced to administrative role. Worst of it was that "peace track" was not informed at all about plans nor works of "war track", and only place where both these chains met was in person of Piłsudski himself, who was both General Inspector and Minister.
Rayski attempted to strenghten the air force and especially to develop strong aviational industry, but for the most time he acted in doctrinal vacuum, since he had no information on planned doctrine beyond some vague instructions by Piłsudski about emphasis on army cooperation and liason tasks. In fact, beyond certain bureaucratic and budgetary constraints, he enjoyed almost complete freedom of action (largely due to lack of serious interest in aviation on higher levels of the command chain) as head of DŻP, in 1927 renamed Departament Aeronautyki MSWojsk (Department of Aeronautics of M.M.A.).

Piłsudski's death in 1935 created new political situation, that eventually led to partial overhaul of command arrangement. While it's core structure remained intact, finally first aviational-related department in GISZ was formed on 4 july 1936, with gen. Gustaw Orlicz-Dreszer (from cavalry) as it's head: Inspektorat Obrony Powietrznej Państwa (IOPP, Inspectorate of State Air Defence). Unfortunately, Orlicz-Dreszer died in air crash just 12 days later, and was succeeded by gen. Józef Zając (from infantry). Roughly at the same time, Departament Aeronautyki (still headed by Rayski), was reorganized into Dowództwo Lotnictwa (Aviation Command). Sadly, soon after both these institutions formed their own (totally unrelated and not cooperating with each other at all) Air Staffs.

In 1936 a long-term plan of general military modernization was drafted. As part of it, Rayski presented between 1936 and 1939 series of sub-plans for aviation. Main things that all these plans had in common was gradually shrinking number of planned squadrons (due to budget issues) and main emphasis on bomber aviation, with fighter aviation being seriously under-invested (with sad results in september 1939).

Due to disagreements about planned organization of the air force, Rayski resigned from his post in january 1939 and was replaced by gen. Władysław Kalkus. Soon after gen. Zając's post was upgraded to Naczelny Dowódca Lotnictwa i Obroy Przeciwlotniczej (Chief Commander of Aviation and Anti-Aircraft Defence) - though still only within "war track". By that time impracticality of dual-track arrangement was becoming obvious to some officers, finally leading then-minister, gen. Kasprzycki to subordinate Kalkus to Zając, though because such inter-track subordination was expressly forbidden by regulations, Kalkus was made subordinate not "functionally" (as ministry's aviation chief to inspectorate's aviation chief) but "personally" (as one officer to another).
In the last months before war Zając and Kalkus made frantic efforts to modify production plans (towards fighters) and to procure aircraft abroad (ordering, among others, Hawker Hurricanes, Morane MS.406s and Fairey Battles), but side effect of it was creating some chaos in industry at the worst possible moment.

Training Establishments

By the end of Polish-Soviet War Poland's military aviation had 8 schools (4 pilots', 4 observers' and 2 technical), but quickly that number was streamlined to just 4 institutions, including 3 training aviational personnel: Niższa Szkoła Pilotów (Lower Pilots' School) in Bydgoszcz, Wyższa Szkoła Pilotów (Higher Pilots' School) in Grudziądz and Oficerska Szkoła Obserwatorów Lotniczych (Officers' School of Aviational Observers) in Toruń.
That last school was disbanded in 1924 and was used as basis to form an air regiment, but in 1925 in Grudziądz additional Oficerska Szkoła Lotnicza (Officers' Aviational School) was formed, in 1927 moved to Dęblin and renamed Szkoła Podchorążych Lotnictwa (Officer-Cadets of Aviation School). Also in 1925 Lower School was renamed Centralna Szkoła Podoficerów Pilotów (Central School of NCO Pilots).
Two years later, "Higher School" in Grudziądz was disbanded and in it's place Szkoła Strzelania i Bombardowania (School of Gunnery and Bombardment) was formed (though it was still running courses of aerobatics for pilots).
In 1929 these schools were reorganized, and in effect there were:
-Centrum Wyszkolenia Oficerów Lotnictwa (Aviation Officers' Training Centre) in Dęblin,
-Centrum Wyszkolenia Podoficerów Lotnictwa (Aviation NCOs' Training Centre) in Bydgoszcz,
-Lotnicza Szkoła Strzelania i Bombardowania (Aviational School of Gunnery and Bombardment) in Grudziądz.
Further reorganization occured in 1937, when Gunnery School was disbanded and it's aerobatics courses moved to Ułęż, and two other schools were renamed Centrum Wyszkolenia Lotnictwa numer 1 and Centrum Wyszkolenia Lotnictwa numer 2 (Aviational Training Centre no.1/2) respectively.
Additionaly there was technical training school, youth cadet school and reserve pilots school. Also, each air regiment had a training squadron.
Balloon troops had their own school - initially in Poznań, then in Toruń (until 1934).

Operational Units

As was mentioned before, in early 1920 air squadrons (sing. eskadra lotnicza, plur. eskadry lotnicze) were combined into Grupy Lotnicze (sing. Grupa Lotnicza, Aviational Group), in april 1920 renamed into Dywizjony (sing. Dywizjon, rougly Wing equivalents) - 4 reconnaissance, 2 fighter and 3 reserve, plus a Morski Dywizjon Lotniczy (Maritime Air Wing - sometimes translated as Naval Air Squadron - issues with translation of Polish terms "eskadra" and "dywizjon" into english are described here, in point 4: viewtopic.php?p=66411#p66411).
Over the next year some minor adjustments followed, and on 15 february 1921 operational units of the Polish military aviation were as follows:
-I Dywizjon - Warszawa - with 1th, 8th and 16th reconnaissance squadrons,
-II Dywizjon - Łuck (now Lutsk on Ukraine) - 6th reconnaissance squadron,
-III Dywizjon - Lwów (now Lvov on Ukraine) - 5th reconnaissance and 7th fighter squadrons,
-IV Dywizjon - Brześć Litewski (now Brest on Belarus) - 3rd, 12th reconnaissance and 18th fighter squadrons;
-V Dywizjon - Bydgoszcz - 13th and 15th fighter squadrons,
-VI Dywizjon - Kraków - 10th reconnaissance squadron,
-VII Dywizjon - Grudziądz - 14th reconnaissance squadron
so total of 13 squadrons in 7 wings.
Also, there were three "aeronautical" (balloon) battalions with Caquot M2 and R2 observation balloons:
-I Batalion Aeronautyczny - Poznań,
-II Batalion Aeronautyczny - Jabłonna,
-III Batalion Aeronautyczny - Toruń,
Note: Polish name for reconnaissance squadron was eskadra wywiadowcza, for fighter squadron eskadra myśliwska.

In the mid-1921 next reorganization followed, with wings being grouped into three air regiments:
-1 Pułk Lotniczy in Warsaw,
-2 Pułk Lotniczy in Kraków,
-3 Pułk Lotniczy in Poznań.
and six lighter-than air battalions (three already mentioned, two new in Kraków (IV) and Brześć (V) plus an airship battalion in Toruń with single Zodiac VZ-11 Vedette blimp.

Following the gradual strenghtening of the air force under generals Leveque and Zagórski, three more regiments were added until 1925:
-4 Pułk Lotniczy in Toruń in 1924 (formed from disbanded Oficerska Szkoła Obserwatorów Lotniczych),
-11 Pułk Myśliwski (Fighter Regiment) in Lida (now on Belarus) near Wilno (now Vilnius on Lithuania) in 1924, in 1926 renamed 5 Pułk Lotniczy,
-6 Pułk Lotniczy in Lwów in 1925.
On the other hand, lighter-than-air units were reduced in 1924 to single battalion in Toruń, with detached company in Jabłonna (which in turn was upgraded to second battalion in 1929).

Forming of 11 Pułk Myśliwski reflected Leveque's and Zagórski's expansion plans, that called for not only mixed regiments, but also specialized (fighter, bomber, reconnaissance) regiments. However since these plans were dropped in second half of the 1920s, unit was reorganized into "typical" mixed regiment.
Typical regiment was supposed to contain at least one bomber-reconnaissance wing, or "line wing" (Dywizjon Liniowy) and one fighter wing (Dywizjon Myśliwski). In reality, though, achieving that state took quite a lots of time and effort. On the other hand, regiment in Warsaw was typically stronger, with additional bomber wing(s), initially called "destroyer wing" (Dywizjon Niszczycielski, later Dywizjon Bombowy). Additionaly each regiment had training squadron (eventually wing), liason and transport elements etc.
On a note: each reorganization was typically followed by squadron renaming.
In late 1920s new type of sqadrons appeared, namely "accompanying" (army co-operation) ones (sing.Eskadra Towarzysząca) shortly before war renamed to "observation" - Eskadra Obserwacyjna), reflecting post-1926 emphasis on army support duties. These squadrons were organized into 3-plane platoons (instead of "flights" in other squadrons), that were to be attached to infantry divisions and cavalry brigades for observation and liason duties. While sound idea in principle (as evidenced by service of Pipers and Austers during WW2 and by helicopters ever since), in practical realities of september 1939 it ended in disaster, when slow and light aircraft of these units were easy prey for Messerschmitts enjoying air superiority.

In may 1939 operational units of the Polish Military Aviation were as follows:
1 Pułk Lotniczy - Warszawa
-III Dywizjon Myśliwski (111, 112 Eskadra Myśliwska),

Planned grand total of the whole air force: 12 brigades and regiments, 31 wings, 64 squadrons, 692 aircraft.

Aviational Industry

Some details about Polish aviation industry of the era have been already mentioned in various posts in this thread, so here I'll just give a brief outline of major manufacturers to link it all together.

First aircraft manufacturer of independent Poland were Centralne Warsztaty Lotnicze (CWL, Central Aviational Workshops) organized in Warsaw in november 1918. Their primary task was initially maintenance of the aircraft, but in 1919 they made attempt to produce copy of Hannover CL.II aircraft and in mid-1920s also license-production of French Hanriot trainers. Also several attempts were made there to develop various domestic aircraft. In 1928 they were reformed into Państwowe Zakłady Lotnicze (PZL) (further below).
Also in 1919 Wojskowe Zakłady Lotnicze (Military Aviational Workshops) in Kraków and Lwów produced small amount of Hansa Brandenburg B.I
biplanes, but their activity in field of manufacturing was short-lived.

Zakłady Mechaniczne E. Plage i T. Laśkiewicz (Mechanical Works E. Plage and T. Laśkiewicz) was Poland's first "true" (commercial) aircraft manufacturer. Company existed since 1860 as mechanical workshop and steam boiler producer, gradually expanding their activities. In 1920 they begun producing aircraft, initially on Italian license. Because the workforce lacked experience with that kind of production, quality of their manufacture was initially extremely low, but gradually these issues were overcome and in mid-1920s factory acquired contract for license-production of French Potez aircraft, followed by Dutch Fokker transports. In late 1920s Plage i Laśkiewicz's chief designer become Jerzy Rudlicki, who designed a many various types of aircraft manufactured under brand Lublin. Rudlicki also invented V-tail, used later on Beech Bonanza, Fouga Magister and F-117. In 1935 factory was forced into bankruptcy and nationalized by military authorities, which subsequently renamed it Lubelska Wytwórnia Samolotów (LWS, Lublin Aircraft Factory). Under that name it continued operations until 1939.

In 1923 in Poznań Wielkopolska Wytwórnia Samolotów "Samolot" (WWS Samolot, Greater Poland Airplane Factory "Airplane") was formed. Initially it produced mostly trainers on French license, but gradually it started production of trainers designed by Ryszard Bartel. Results of 1929 crisis, together with fire that broke out in factory, led to factory's demise with some of it's activities (and personnel) being taken over by PZL and PWS.

Also in 1923, but in Biała Podlaska, a Podlaska Wytwórnia Samolotów (PWS, Podlasie Airplane Factory) was formed. It begun with license-manufacturing of French aircraft, followed by Bartel planes and finally with own designs. In 1932 factory was nationalized and in 1936 subordinated to PZL (without re-branding). Factory was destroyed by aerial bombardment in september 1939.
Early and mid 1920s were period of brief but notable activity of Polish-French company Francopol. It will be described together with SPAD 61 fighter.

One of the most famous brands of the Polish aviation industry was RWD, whose name was an acronym from the names of the brands leading designers: Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, while the manufacturers' actual name was Doświadczalne Warsztaty Lotnicze (DWL, Experimental Aviational Workshops). It originated in to 1925 when the Sekcja Lotnicza Koła Mechaników Studentów Politechniki Warszawskiej (Aviational Section of the Circle of Mechanics of Students of Warsaw Institute of Technology) was formed. It produced many successful sports planes and military trainers, and was only major aircraft manufacturer that succesfuly resisted nationalization efforts of the military authorities in 1930s.

Państwowe Zakłady Lotnicze (PZL, State Aircraft Works) were formed in 1928 from CWL. Their first product was French Wibault 70 made on license, but soon they started manufacturing modern monoplane all-metal fighters designed by Zygmunt Puławski. Until the war PZL produced many interesting and often highly advanced planes, mostly of military types. By 1939 it had two airframe factories (in Warsaw and in Mielec) and two engine factories (in Warsaw and in Rzeszów).

Other notable manufacturers of aviation-related equipment were Państwowe Wytwórnie Uzbrojenia (PWU, State Armament Manufacturers) - producing armament, ordnance and ammunition, Państwowe Zakłady Inżynierii (PZInż, State Engineering Works) - Poland's main manufacturer of ground vehicles, but also with large metallurgical sector, and Polskie Zakłady Optyczne (PZO, Polish Optical Works).

War

Polish Militar Aviation was put on war footing already on 24 august 1939, which resulted in disbandment of all air regiments and subordination of their units either to GHQ or to commands of particular field armies. Subsequently all combat aircraft were dispersed to the camouflaged forward airfields, thus when Luftwaffe struck the main bases on 1 september, it managed to destroy number of auxiliary aircraft and infrastructure, but inflicted little losses to front-line aircraft (only 7% of combat aircraft was actually destroyed by Germans on the ground).
Before the mobilization stregth of the air force was around 10000 men, reaching 12043 by 1 september (with planned mobilization stregth around 17000, but this was unfortunately never fully achieved), including 1441 officers, 3602 NCOs and 7000 private - of it 1181 pilots, 497 observers and 219 gunners.
Aircraft strength on 1 september was as follows:
-159 fighters active and 118 in reserve, training and maintenance (30+75 P.7 and 129+43 P.11),
-36 bombers active and 40 in reserve, training and maintenance (36+40 PZL 37 Łoś and 15 LWS-4 Żubr in reserve),
-118 bomber-reconnaissance planes active and 85 in reserve, training and maintenance (all PZL 23 Karaś),
-83 observation aircraft active and 135 in reserve, training and maintenance (48+95 Lublin R.XIII and 35+40 LWS Czapla).
Naval aviation had 25 airplanes, including 23 floatplanes and flying boats.
Additionaly there wes around 1000 training and auxiliary planes, including 600 trainers (RWD-8, PWS-16, PWS-18, PWS-26) and rest being transport, liason, air ambulance planes, as well as number of stored aircraft of outdated combat types.

Opposite that there were two German Luftflotten (1 and 4) with nearly 2000 planes, including 648 bombers, 219 dive-bombers, 30 attack planes, 210 fighters, 474 reconnaissance and transport aircraft, 348 other support and air defence aircraft.

Despite the valiant Polish resistance, German air force, which enjoyed both numerical and technological superiority managed to eventually gain total supremacy in the air. Polish air units, together with whole army, were gradually pushed towards south-eastern areas of Poland, where it was hoped that it will be able to create a stronghold until expected French-British offensive on Western Front. However Soviet agression on 17 september 1939 made these hopes impossible, and on 17 and 18 september remaining combat formations of the air force had to evacuate to Romania and Hungary, where they were interned. Only active air units that remained in operation on Polish soil after that date were some ad-hoc flights in besieged Warsaw and aviation of "Narew" Group (which made last flights on 2 october 1939).

In total, Polish Military Aviation lost 327 front-line aircraft (average type losses around 75%), 234 members of flying personnel (61 KIA, 63 WIA, 110 MIA).
Still, the German losses were also high: around 130 aircraft shot down in air combat, 150 shot down by anti-aircraft fire and next ca. 280 heavily damaged and subsequently written off. Polish bomber aviation conducted 230 bombardment and 80 reconnaissance missions, dropping 172 tons of bombs (relatively low number, caused by certain hesitation of GHQ) plus several dozen tons dropped by bomber-reconnaissance units of army aviation.

Although Poland was overrun by nazis, that didn't mean the end of Poland's air force in World War 2. Soon forming of Polish Armed Forces in Exile - in France and Great Britain - begun, including air units. There, they continued their fight until the very last day of the war in Europe.

As my esteemed friend said before, now we start with new chapter. I hope you will like it.

Polish military aircraft 1923-1926

Training Aircraft

[ img ]

In the first half of the 1920s Polish Military Aviation badly needed new trainers, as the ones already in use were badly worn-out. In 1923 50 Hanriot HD-14 trainers and 2 HD-14S air ambulances were purchased in France, together with the right to license manufacture them. Significantly modified version designated H-28 was produced in Centralne Warsztaty Lotnicze (CWL, Central Aviational Workshops - 125 aircraft) and in Wielkopolska Wytwórnia Samolotów (WWS, Greater Poland's Aircraft Factory - 136 aircraft, including 16 H-28S air ambulances). They were used for initial training in flight schools, as well as refresher trainers in the training squadrons of the Air Regiments and as liason planes. From 1929 they were gradually removed from service (until 1935) and either scrapped or transferred to aeroclubs, where they flew until late 1930s.

6 Hanriot HD-19bis together with right to license manufacture were bought in 1924. 80 such aircraft were produced in WWS - 50 as H-19 and 30 more modified H-19a (with modified engine cooling installation). Between 1929 and 1935 they were gradually retired and scrapped.

[ img ]

Morane-Saulnier AR-35EP2 airplanes were purchased in 1925 as advanced trainers - total of 70 were used, mainly in flight schools, but also as liason aircraft. Between 1929 and 1935 they were gradually removed from service and transferred to aeroclubs, where they flew until late 1930s.

[ img ]

BM-2 was a prototype trainer, designed by Ryszard Bartel from WWS for a contest organized by military aviation for designs of various types of aircraft. examples (one flying, one for ground tests) were built in 1926. Considered a good design, it formed a basis for the Bartel's BM series of trainers.

Fighters

[ img ]

In 1925 and 1926 a total of 256 SPAD 61C1 fighters were bought in France. Additional 100 were to be produced on licesnse by Polish-French company Francopol, but this entity ended it's existence in 1926 in the air of scandal - in july 1926, despite taking large downpayments (largely misapropriated) - it was supposed to have 55 aircraft completed but had only 2 bare airframes partially made, which led to transferring of the order to CWL, but there only around 10 planes were made before whole contract was cancelled. In the late 1920s S.61's were basic equipment of Polish fighter aviation, serving in 11 fighter squadrons, 2 training squadrons and several flight schools. Although fast and agile, they had serious problems with durability (often leading to disintegration in flight), quickly gaining reputation of flying coffins and by early 1932 were removed from service.

Bombers

[ img ]

In 1926 32 Farman 68BN4 Goliath bombers were purchased for planned heavy/night bomber squadrons. For a short period (1928-1930) they served in two destroyer (bomber) squadrons of the 1 Pułk Lotniczy (1st Air Regiment) in Warsaw (but were quickly replaced due to the abysmal performance of their engines) and until 1933 for training purposes (including parachute training).

Line Aircraft (Bomber-Reconnaissance)

[ img ]

French Potez XVA2 aircraft were primary equipment of Polish "line squadrons" (bomber-reconnaissance) in the late 1920s and early 1930s. Total of 305 were purchased between 1924 and 1927 - 170 directly from France, 100 built on license at Plage i Laśkiewicz works in Lublin and 35 more by Podlaska Wytwórnia Samolotów (PWS, Podlasie Aircraft Factory). They were used by 16 line squadrons and 2 night bomber squadrons, from which they were gradually removed after 1929 and transferred to flight schools where they served in large numbers until 1936-1937.

[ img ]

Breguet XIXB2 was - together with Potez XV - primary equipment of Polish "line squadrons" (bomber-reconnaissance) in the late 1920s and early 1930s, but while Potez were to be used mainly for reconnaissance, Breguets were viewed primarily as bombers. Total of 256 were bought (236 Br.XIXB2 and 20 Br.XIXB2/GR), equipping total of 11 squadrons, including 2 bomber and 1 night fighter, as well as support and training units. Between 27 august and 26 september 1926 Br.XIX flown by lieut. Bolesław Orliński and sgt. Leonard Kubiak made a transsiberian Warsaw-Tokyo-Warsaw raid (20250 kilometers), returning safely despite losing half of the bottom left wing, damaged propeller and seriously overworked engine. Majority of the Br.XIX's were retired by 1936 (some were sold to Spanish Nationalists), but few remained in service as auxiliaries until early 1939.

[ img ]

Potez XXVII was an upgraded version of Potez XV with modified wings. They were bought in 1926 by Polish military aviation - 90 P.XXVIIA2 directly from France and 155 more produced on license at PWS, to a total of 245. They served in 13 line squadrons, 2 bomber squadrons and briefly in 2 acompanying (army co-operation) squadrons. They were quickly considered outdated and transferred to flight schools between 1929 and 1932, last few serving there until september 1939.

[ img ]

Despite to foreign purchases, military aviation authorities hoped for getting a domestic design of the "line" aircraft. To that end, they approached Władysław Zalewski from the CWL, asking him to update his WZ-VIII design (see Experimental and unbuilt aircraft below) or to design wholly new plane. Zalewski choose the second option, and eventually in august 1926 the prototype of CWL WZ-X bomber-reconnaissance aircraft was first flown. Total of 4 such aircraft were made, but series production was not started due to over-abundance of Potez and Breguet aircraft that were purchased in numbers greatly exceeding needs of Polish military aviation. CWL WZ-X planes remained in service as operational trainers until the second half of the 1930s.

Maritime Aircraft

[ img ]

4 flying boats Liore-et-Olivier (LeO) H-13 were bought in 1924 (2 H-13B2 and 2 H-13E) for the Morski Dywizjon Lotniczy (MDLot, Maritime Air Wing - sometimes translated as Naval Air Squadron). While comfortable in flight, they suffered from poor quality of manufacture and served mainly as trainers until 1929-1931.

[ img ]

4 CAMS 30E flying boats were delivered in 1925 and served in MDLot as trainers, but occasionaly also as observation aircraft, until 1931.

[ img ]

Latham 43HB3 was chosen as "heavy combat hydroplane" for service in MDLot and 8 were bought in 1926 to be used mainly as patrol planes, but also for operational training until retired in 1933.

[ img ]

Schreck FBA-17 flying boats were main equipment of Polish naval aviation in late 1920s and early 1930s with total of 18 purchased (6 FBA-17HE2 trainers and 12 FBA-17HMT2 observation-liason aircraft). Besides the main base of MDLot in Puck, they served in the Pluton Lotniczy Flotylli Rzecznej (Aviational Platoon of the Riverine Flotilla), in 1932 renamed to Rzeczna Eskadra Lotnicza (Riverine Aviational Squadron) on the Prypeć (Pripyat) river in then-eastern Poland's Polesie region. Majority of FBA-17's were retired by 1938, but last one remained in service as liason aircraft until the war.

[ img ]

Liore-et-Olivier (LeO) H-135B3 reconnaissance-bomber flying boats were the last planes of that category purchased in France. 7 were delivered in 1926 and kept in front-line service until 1933, with last one serving as target tug until 1938.

Experimental and Unbuilt Aircraft (selected)

[ img ]

In late 1919 design team of CWL led by Władysław Zalewski begun work on reconnaissance-bomber aircraft designated WZ-VIII DeŻePe (from Departament Żeglugi Powietrznej - Department of Aeronautics (of the Ministry of Military Affairs). It was to have total weight of 1800 kg and be powered by (probably Rolls-Royce Eagle engine (two such engines were purchased as spares for the Handley-Page O/400 - see first post of this thread). Works were interrupted by Battle of Warsaw in 1920 during which partially built prototype was damaged, and ultimately cancelled.

[ img ]

In 1919 Konrad Kucfir designed a twin engined VTOL tail-sitter, which he offered to the Polish military aviation. B ecause of the revolutionary (and also could be said, with hindsigh, rather not practical with the technology of the da y) layout of the design it met with no interests from authorities, although the designer eventually (in 1925) acquired patent on it. In essence it was a "typical" biplane standing on a large tripod, with another set of biplane wings pro vided instead of normal airscrew (itself shaped like large propeller blades) attached to a central "drum" structure wi th two radial engines installed back to back, which in turn gave power to pair of standard propellers attached to the wing-screw arrangement.

[ img ]

Stemal-III was an experimental plane made by Stefan Malinowski in workshops of the flight school in Bydgoszcz, based on fuselage of Nieuport 80/81 but with new wing of variable airfoil. Plane was first flown in Warsaw in august 1922, but despite promising results of the tests (shorter take-off and landing run, higher vertical speed, higher ceiling and lower minimum speed) works on it were not continued.

[ img ]

In the years 1922-1923 Wladyslaw Zalewski has designed (purely on his own initiative) a small (wingspan 8,6m, lengt h 5,8m) fighter with propeller located in the middle of the fuselage length (similarly to French WW1 fighter Dufaux C. 2) and powered by 300hp Hispano-Suiza engine. Because of the highly peculiar character of the design it failed to attr act any interest from the authorities.

[ img ]

BM-1 Maryla (name of designer's wife) was a fighter plane with interesting arrangement of landing gear, designed in 1924-1925 by Ryszard Bartel from WWS for a contest organized by military aviation for designs of various types of aircraft. Although it won the contest in the category of fighters, planned construction of prototype and serial production never materialized.

[ img ]

CWL WZ-IX Pteranodon was a project of heavy bomber made by Władysław Zalewski from CWL for the same contest as BM-1 and BM-2. It was a quite design with all-metal structure covered with canvas. Apparently two versions were designed - two and three engined, but curiously, most publications mention only either one of them. Although a promising design, it was far outside the capacities of the Polish aviation industry of the time and remained only on paper.

[ img ]

Cpt. Aleksander Sipowicz worked in research and maintenance offices of the air force headquarters. In the early 192 0s he was studying contemporary aerodynamic research findings and conceived the idea of a wing set an anhedral angle ( which would improve stability and lift) and further enchanced by supplementary supporting surfaces merged with wing st ruts. To test his theories, at Centralne Warsztaty Lotnicze he had a Nieuport 12 modified with new wing and parts of t ail from Ansaldo Balilla and flown in 1926. Although the idea proved apparently sound, the authorities expressed no in terest and further works were cancelled.

[ img ]

In 1926 WWS built an experimental light aircraft that could be used as light fighter, liason or sports plane, and which contained many advanced design features, including (among others) wooden stressed skin fuselage and wings connected to fuselage by ball joints (allowing quick installation or removal) and use of riveting instead of welding. Plane was test-flown in 1926, but no production orders were made.

[ img ]

PWS-3bis was a projected observation derivative of small sports plane first flown in 1927. Upper part of the fuselage was detachable, allowing for easy conversion to various purposes. While the idea was not continued in Poland, it was copied without license in France on Breguet 270/271.

You make a great team, eswube and Rhade. Brilliant drawings as always, and it's interesting to read the descriptions for each. Shame the CWL WZ-IX never flew, she looks nice.

Again so much to learn from this thread, a few types I'd never heard of before there and some great artwork. The long historical essay is also well worth reading. This post is nothing less than we've come to expect from this thread, and we know there's so much more to come!
