Overview
Caspar-Werke was a German aircraft manufacturer active during the formative years of aviation. The enterprise was established in 1911 by Karl Caspar in Fuhlsbüttel under the name Zentrale für Aviatik. Its early business reflected the conditions of the pre-First World War aircraft industry: rather than relying exclusively on original designs, the company built aircraft types developed by other manufacturers under licence. Among the licensed designs associated with its early activity were aircraft from Etrich and Rumpler. The company’s first phase ended in the aftermath of the First World War. Like many German aviation enterprises, it operated in an environment transformed by wartime production, post-war restrictions, and the disruption of the German aircraft industry. Caspar subsequently re-established the business in 1921 at Travemünde, a location that became central to the company’s later identity and operations. The Travemünde period brought a stronger design focus. Ernst Heinkel served as chief designer after the company’s re-establishment, but he left in May 1922 following a dispute concerning rights to a design. Heinkel was succeeded by Ernst Ritter von Lössl. Hans Herrmann, formerly associated with Udet Flugzeugbau, later joined the company as a designer. These changes illustrate the fluid movement of engineering talent among German aircraft manufacturers during the interwar period. Caspar-Werke developed and listed a number of aircraft designs during its second phase, including the Caspar C 24, C 26, C 27, C 30, C 32, C 33, C 35, and U.1. It also produced the CC 15 and CST 18 as projects. The surviving record presents the company as a relatively small and historically short-lived manufacturer rather than as a mass-market aviation brand. Its significance lies principally in its place within Germany’s early aircraft-manufacturing network, its licensed production work, its Travemünde design office, and its association with engineers such as Heinkel, von Lössl, and Herrmann. Caspar-Werke ceased operations in 1928. It therefore has no current commercial operations, active product portfolio, public listing, or modern corporate parent identified in the available reference material. In historical terms, the name refers to a defunct German aerospace manufacturer whose activity spanned the pre-First World War period and the unstable development environment of German aviation in the 1920s.
History
Caspar-Werke originated in 1911 when Karl Caspar founded an aviation enterprise in Fuhlsbüttel under the name Zentrale für Aviatik. The firm entered aviation at a time when aircraft manufacturing was still developing as an industrial sector and when companies frequently combined licensed construction with experimental design work. During its initial phase, Caspar-Werke built aircraft based on Etrich and Rumpler designs under licence, giving the company a role in the distribution and manufacture of established aircraft types rather than relying solely on proprietary models. The First World War and its aftermath interrupted the company’s early development. The available historical account states that the original enterprise was dissolved after the war. In 1921, Karl Caspar re-established the firm at Travemünde. This second phase placed greater emphasis on aircraft design and brought the company into contact with prominent German aviation engineers. Ernst Heinkel became chief designer following the re-establishment, but his tenure was brief. He left in May 1922 after a dispute concerning rights to a design. Ernst Ritter von Lössl then replaced him, and Hans Herrmann, formerly connected with Udet Flugzeugbau, later worked as the company’s designer. The Travemünde company was associated with several aircraft designations. The C 24, C 26, C 27, C 30, C 32, C 33, and C 35 formed part of the Caspar design sequence, while the U.1 was another aircraft associated with the manufacturer. The CC 15 and CST 18 are identified as projects rather than completed production aircraft. The available record does not provide enough information to establish the production quantities, technical specifications, customer base, or operational histories of each designation without risking unsupported detail. Caspar-Werke ceased operations in 1928. Its existence was therefore relatively short, but it occupied a recognizable place in the early German aircraft industry. The company’s history combines three characteristic elements of that sector: licensed production before the First World War, reorganization after the conflict, and the use of mobile engineering expertise in the competitive German aviation environment of the 1920s. The company is now a historical subject rather than an active aerospace business.
- 1928

[1]Caspar-Werke ended operations, bringing its interwar aircraft-manufacturing activity to a close.
- 1922
Change in chief design leadership
[1]Ernst Heinkel left in May 1922 after a dispute over rights to a design and was replaced by Ernst Ritter von Lössl.
- 1921
Re-established at Travemünde
[1]Karl Caspar re-established the enterprise at Travemünde, beginning its second major phase as an aircraft manufacturer and design organization.
- 1919
Post-war dissolution
[1]The original company was dissolved following the First World War. The exact date is not specified in the reference material; 1919 is used here as a period marker for the post-war transition.
- 1911
Company founded in Fuhlsbüttel
[1]Karl Caspar founded the aviation enterprise Zentrale für Aviatik in Fuhlsbüttel, marking the beginning of the business later known as Caspar-Werke.

Products and positioning
An early German aircraft manufacturer combining licensed construction with in-house aircraft design during the pre-1914 and interwar periods.
Licensed aircraft production
Licensed Etrich aircraft
Caspar-Werke built aircraft types developed by Etrich under licence during the company’s early period. The available reference identifies the licensed relationship but does not specify individual variants, production totals, or customer operators.
Licensed aircraft production
Licensed Rumpler aircraft
The company also constructed Rumpler aircraft types under licence. This activity formed part of Caspar-Werke’s early manufacturing model, which combined licensed production with later proprietary and experimental designs.
Aircraft
Caspar C 24
The C 24 was one of the aircraft designations associated with Caspar-Werke’s Travemünde-era design program. The supplied historical material does not establish whether it reached series production or provide reliable technical specifications.
Aircraft
Caspar C 26
The C 26 formed part of Caspar-Werke’s sequence of aircraft designs. Available reference material identifies the designation but does not provide sufficient detail about configuration, production, or service use.
Aircraft
Caspar C 27
The C 27 was an aircraft associated with Caspar-Werke. Its inclusion in the company’s aircraft list indicates a design or production program, but the available source does not document its detailed development history.
Aircraft
Caspar C 30
The C 30 was one of the Caspar-Werke aircraft designations from the company’s interwar activity. No verified information is available in the supplied material on its manufacturing scale or operational deployment.
Aircraft
Caspar C 32
The C 32 belonged to Caspar-Werke’s later aircraft program. The reference confirms the designation but does not support a fuller technical description without additional sources.
Aircraft
Caspar C 33
The C 33 was listed among Caspar-Werke’s aircraft. It is best treated as a historical company design or aircraft program because the supplied material does not clarify its production status.
Aircraft
Caspar C 35
The C 35 was another aircraft designation connected with Caspar-Werke’s Travemünde-era work. Detailed specifications and evidence of completed production are not provided in the available reference.
Aircraft
Caspar U.1
The U.1 was an aircraft associated with Caspar-Werke. The surviving summary identifies the model name but does not provide enough information to characterize its design or operating history accurately.
Aircraft project
Caspar CC 15
The CC 15 was recorded as a Caspar-Werke project rather than a confirmed production aircraft. Its designation reflects the company’s experimental design activity during the interwar period.
Aircraft project
Caspar CST 18
The CST 18 was identified as a Caspar-Werke project. The available source does not document construction, production, or operational service, so it is classified as project-only.
