Stemme

Stemme is a German aircraft manufacturer best known for self-launching motorgliders and touring aircraft. Its business has combined aircraft development and production with technical support activities, including service, maintenance, and repair for sports and personal aircraft. The company’s identity is closely associated with the Stemme S10, an original self-launching motorglider that established the product family, and with later aircraft such as the S6 and S12 touring motorgliders. Stemme’s aircraft occupy a niche between conventional sailplanes and light powered aircraft. A self-launching motorglider can take off under its own power and then operate as a glider, giving owners a combination of powered-aircraft utility and soaring capability. This positioning has made Stemme relevant to private pilots, touring users, and specialist aviation customers seeking efficient long-distance flight and retractable-engine motorglider designs. The company’s industrial history includes cooperation with Remos AG. From 2014, a number of structural components for Stemme gliders were produced under contract by Remos. In April 2017, Stemme AG and Remos AG merged under the Stemme AG name. Remos was associated with the Remos GX series of light aircraft, and the combined organization retained both Stemme and Remos as continuing brands. The merger also preserved the two operating locations and included plans to expand the former Remos facility in Pasewalk. Stemme’s documented aircraft range includes the S10, S6, and S12. The S12 is identified as a touring motorglider and the company’s current production model in the referenced material. Stemme also developed the S15, a prototype unmanned aerial vehicle based on the S6. The S15 formed the basis for the SAGEM Patroller, while the Stemme ASP S15 represented another designation associated with the platform. Leadership changed in September 2019, when Bart Slager became chief executive officer, replacing Paul Masschelein after Masschelein had served approximately six and a half years in the role. The available reference material does not establish a more recent corporate ownership structure, financial profile, public listing, or official website address. Stemme is therefore best described as an active aviation brand within a specialized German aircraft-manufacturing and support business, with its brand portfolio continuing alongside Remos following the 2017 combination.

Stemme is a German glider and motorglider manufacturer whose business has also included support for sports and personal aircraft. Its production profile is centered on self-launching and touring motorgliders, aircraft that combine an onboard propulsion system with the ability to operate as sailplanes. The company’s original aircraft was the Stemme S10, which became the foundation of the brand’s specialist identity. The company later expanded its range with the S6 touring motorglider and the S12, another touring motorglider identified in the available reference material as the current production model. In addition to civil and recreational aircraft, Stemme developed the S15 as a prototype unmanned aerial vehicle based on the S6. The S15 was subsequently associated with the SAGEM Patroller unmanned aircraft, and the Stemme ASP S15 designation also appears in the company’s aircraft history. Stemme’s activities have not been limited to manufacturing. Its business has been described as including service, maintenance, and repair for sports and personal aircraft, giving the company an aftermarket and technical-support role in addition to its design and production work. A significant industrial development occurred in 2014, when many structural components for Stemme gliders began to be produced under contract by Remos AG. Remos was a German aircraft manufacturer associated with the Remos GX light-aircraft series. This supplier relationship was followed by a broader corporate combination. In April 2017, Stemme AG and Remos AG merged under the Stemme AG name. The combined company retained both operating locations, planned an expansion of the former Remos facility in Pasewalk, and continued to market Stemme gliders and Remos lightplanes as separate brands. The leadership of the business changed in September 2019. Bart Slager became chief executive officer, replacing Paul Masschelein, who had held the position for approximately six and a half years. The available reference material does not provide a confirmed founding year, founder, current owner, financial data, public-market listing, or a verified current website address. It also does not establish whether the Stemme corporate entity has subsequently changed legal form or ownership. Accordingly, the documented history is strongest on the aircraft range, the relationship with Remos, the 2017 merger, and the 2019 chief executive transition.
