LWS = Lubelska Wytwórnia Samolotów (Lublin Aircraft Factory)
POLAND


LWS-1 (first use of this number) - 1935, light fighter, single-seat single-engine low-wing monoplane with enclosed cockpit and semi-retractable undercarriage, only project, designed by PZL factory as PZL-39, later known as LWS-4

LWS-1 (second use) - 1934, torpedo bomber and reconnaissance twin-float seaplane, five-seat twin-engine low-wing monoplane with enclosed cockpits, only 1 prototype built as Lublin R-XX (with open cockpits), designed by "Zaklady Mechaniczne E. Plage & T. Laskiewicz" factory in Lublin and hence designated as Lublin R-XXA

R-XX - first prototype

R-XXA - planned production version designated LWS-1 (or maybe LWS-1A)

LWS-2 - 1937, light ambulance aircraft, four-seat (pilot + paramedic + two wounded or injured on stretchers) single-engine high-wing monoplane with enclosed cabin and fixed undercarriage, only 1 built

LWS-3 Mewa (Seagull) - 1937, observation and liaison aircraft, two-seat single-engine high-wing monoplane with enclosed cockpit and fixed undercarriage, see also LWS-7 Mewa II

LWS-3 - 3 prototypes built

LWS-3A - first production version, about 25 built (in various stages of assembly)

LWS-3B - export version for Bulgaria, only project

LWS-3H (hydro) - seaplane version on floats, only project

LWS-4 - see LWS-1 (first use), 1936, only project, later modified version (still only project) probably known as LWS-5

LWS-5 (first use) - see LWS-4, 1937, only project

LWS-5 (second use) - 1936, torpedo bomber and reconnaissance twin-float seaplane, four-seat twin-engine high-wing monoplane with enclosed cockpits, only project (first prototype in early stage of assembly), it was seaplane version on floats of the LWS-6 Żubr land bomber

LWS-6 Żubr (Wisent*) - 1936, medium bomber, four-seat twin-engine high-wing monoplane with enclosed cockpits and retractable undercarriage, 1 prototype + 16 series aircraft built, designed by PZL factory as PZL-30B (hence the prototype was known as PZL-30BI, and after some modifications as PZL-30BII), NOTE: from 60s till about second half of the 90s in many sources it was erroneously designated as LWS-4!

PZL-30BI (after modification renamed PZL-30BII) - first prototype

LWS-6A - first production version, 16 built, one aircraft modified with twin-tail

LWS-6B - planned export version for China with Bristol Pegasus XII engines

Żubr II (Wisent II) - 1939, improved version, new wings and fuselage under construction, it is not known if this aircraft was new built or rebuilt from series LWS-6A, designation LWS-8 not confirmed

LWS-7 Mewa II (Seagull II) - 1939, observation and liaison aircraft, two-seat single-engine high-wing monoplane with enclosed cabin and fixed undercarriage, only project, it was modified version of the LWS-3 Mewa

without model number:

LWS Czapla (Heron) - 1935, observation and liaison aircraft, two-seat single-engine high-wing parasol monoplane with open cockpits and fixed undercarriage, 4 prototypes + 65 series aircraft built, designed by DWL (RWD) factory as RWD-14

Thanks LAW!

How about adding the 'improved' Żubr subtypes?

LWS-6A - improved LWS-6
LWS-6B - export LWS-6A with Bristol Pegasus XII

BTW, a couple of questions:

- Did the 14K-powered LWS-6 proposed for Romania receive its own designation?

- Anything to the speculation of a "LWS-8 Żubr II"?

Thanks Apophenia!

I added a few additions to my list.

Romania was interested in Gnome-Rhone 14K powered version of the PZL-30B (series LWS-6A was not produced at this time). As far as I know, this proposed Romanian version did not receive its own designation.

Żubr II (Wisent II) - see above. Designation LWS-8 is not confirmed in Polish sources.

Regards,

LAW

Thanks LAW. I had guessed that 'LWS-8 Żubr II' was wishful thinking. It's always tempting to attempt to 'rationalize' designation series after the fact ;D

My dear Apophenia,


as in A-Z magazine and many Internet sites,the LWS-4 was the first aircraft
called Zubr I,and LWS-6 called Zubr II.

Thanks Hesham. As LAW noted, the Żubr II was an LWS-6A rebuilt in 1939 but the "LWS-8 Żubr II" designation is not confirmed.

The Zubr designations are very confusing (must have been difficult to be a Polish aircraft spotter in the late 1930's!)
See attached side views of the various Zubr types (top to bottom) the PZL-30/BI, PZL-30/BII, LWS-6 and LWS-4A.

R-XX - first prototype

R-XXA - planned production version designated LWS-1 (or maybe LWS-1A)

The first use of designation LWS-1 was provided just for Lublin R-XX and it was only LWS-1, not LWS-1 A, and the second for PZL-39 fighter :)
For many years in Polish literature designation LWS-4 concerned the modified PZL-30 BII Żubr and relatively lately was fixed LWS-6
but I still wonder why modification of number 6 ( existing LWS-6 ) for hydroplane project had lower number 5 ( LWS-5 ).
