A bit of thread necromancy, I thought I'd expand on AM's original Albatros 'L' series type list.

My next post will cover the same internal Albatros 'L' series type numbers presented numerically. (My third post will cover Albatros acronym designations - and anomalous designations.)

In the Albatros 'L' series type numbers list, relevant Idflieg and Marine type designations are given in the description along with basic information. [1] Details can be frustratingly sketchy at times but, overall, the rationalized Albatros 'L' type list is a surprisingly complete sequence.

There are two notable sequential gaps in the Albatros 'L' numbers - 61-to-64 and 85-to-99. From there, the numerical sequence picks up from L.100 to L.103. Two points need to be made that '100' sequence. First is that L.100 to L.103 were all built - which suggests that we cannot eliminate the possibility of unrealized Albatros projects with higher numbers. Second, the L.101 to L.103 are now better remembered by their later RLM designations - Al 101 to Al 103. As that was an outside imposition, I have stuck with the original Albatros internal style.

Most designs are products of the Albatros Flugzeugwerke GmbH of Johannisthal, southeast of central Berlin. [2] Also mentioned is Albatros subsidiary, OAW - which stood for Ostdeutsche Albatros Werke. OAW - located at Schneidemühl in Posen - was meant to be a production subsidiary. However, original design was performed at OAW on a small scale. The result is some confusing duplicate Idflieg designations. But, fortunately, there are also separate 'L' designations assigned to these OAW offerings.

Style and Usage

The Albatros 'L' series designations are usually presented with a space (eg: L 3) but sometimes without (eg: L3). German usage generally avoids punctuation marks in designations. However, for my own convenience, I have inserted periods into both Albatros 'L' designations and their official military counterparts. My apologies in advance for that.

As the major user of Albatros products, no direct mention has been made of the Luftstreitkräfte. Before Oct 1916, that organization was known by its short-form Fliegertruppen (Air Service) which is mentioned a few times. I have used Marine as a short-form for both the Kaiserliche Marine and its naval aviator branch, the Marineflieger (established in 1913).

_____________________________

[1] Idflieg ((Inspektion der Fliegertruppen) designations covered aircraft types adopted by the Deutsches Heer. Marine type designations, of course, refer to the system assigned by the Marineflieger branch of the Kaiserliche Marine.

[2] Johannisthal field was also the location of Fokker and Rumpler factories. From 1912, the Adlershof-Johannisthal field was the home of the Deutsche Versuchsanstalt für Luftfahrt (DVL of German Experimental Institute for Aviation). In a WWI context, Adlershof is best-remembered for a series of fighter competitions begun in January 1918.

Albatros Acronym Designations and Anomolies

Albatros Flugzeugwerke acronym designations are listed here alphabetically. These include rather generic role or type descriptors. Where known, alternative internal Albatros and military designations. In some cases, it is difficult to distinguish between industry and military appelations - initially, military users retained many of those internal acronyms/descriptors.

The Albatros acronym designations are important for a number of reasons. First, they show Albatros' original approach to type designation - and the limitations of the rather generic type descriptions must have quickly become apparent. Second, not all of the early Albatros aircraft types made it onto the later, rationalized 'L' type list. As a result, we have few records of these early types other than their Albatros acronym designations (especially when contemporary aviation journals' descriptions were often even more generic than Albatros' terminology).

In many cases, individual Albatros acronym designation listings will simply refer to types in the Albatros 'L' sequence (see previous post). However, as noted, some early types never received retroactive 'L' designations. In such cases, a fuller type description is given in this listing. Early Albatros aircraft designs which seem to lack any form of designation will listed first. (Hopefully, if any designations once existed for these types, they will emerge and the listings can be adjusted appropriately.)

(Edit) I have now added the K.351, K.351B, and K.361 to the existing W.1 listing. These airframes were most likely WDD/W.1 variants built by the Kondor Flugzeugwerke in Essen. Apparently, the Albatros-design structures were slightly revised (to suit Kondor's production approach?).

In a number of cases, I have had to speculate at the meaning of acronym designations ... or simply have no plausible guesses. Any filling in of these blanks would be highly appreciated. Likewise for details on the real mystery entries - eg: the DA 1 (L.49 - Edit: see reply #8) and F.1 (L.54) of 1918 for which I have no details at all! As always, any additions or corrections are also most welcome.

[1] Note, 'K' was also for Kampfflugzeug in the original Idflieg designation system. This Idflieg 'K' was quickly replaced by 'G' for Großflugzeug.

Thanks hesham. I had completely forgotten about the SZ-1! I'll add that Sport Zweidecker tomorrow.

The K 351/K361 series I decided to leave out. I went through the reasons in the introduction of Acronym Designations. Personally, I subscribe to the theory that these were Kondor Flugzeugwerke designations for their licensed W.1 variants. However, there's little in the way of evidence.

If anyone has more of the K 351/K 351B/K 361, I'd love to hear about them. I'd also like to hear more on K 351/K 351B differences. As far as I can tell, the K 351 was Benz-powered. If so, might the K 351 and K 351B be one an the same? Does anyone know for sure?
