'''Grob Aircraft SE''', formerly '''Grob Aerospace''', is a German [[aircraft manufacturer]], specialising in [[glider (sailplane)|glider]]s and [[general aviation]].

Since its foundation in 1971, Grob Aircraft produced a range of aircraft. Initially focusing on gliders, it soon grew into other markets. The company has produced a range of [[trainer aircraft]], many of which have been operated in quantity by a number of military air wings. It has also produced specialised high-altitude [[Intelligence, surveillance, target acquisition, and reconnaissance|intelligence surveillance]] and reconnaissance (ISR) aircraft. According to Grob Aircraft, it has delivered over 4,500 airframes which have cumulatively flown over seven million hours across hundreds of operators spread over five continents.<ref>{{Cite web|url=https://grob-aircraft.com/en/company-portrait.html#1|title=Company Portrait|author= Grob Aircraft SE}}</ref>

Since the 1970s, the copious use of [[carbon fiber reinforced polymer]] in the manufacture of its aircraft has been a hallmark of the firm's designs.<ref>{{cite web | url = http://www.dw-world.de/dw/article/0,,3363309,00.html?maca=en-podcast_made-in-germany_en-2108-xml-mrss | title = One of the Last German Airplane Manufacturers&nbsp;— Grob Aerospace | accessdate = 25 February 2009 | archive-date = 11 May 2009 | archive-url = https://web.archive.org/web/20090511003354/http://www.dw-world.de/dw/article/0,,3363309,00.html?maca=en-podcast_made-in-germany_en-2108-xml-mrss | url-status = dead }}</ref><ref name = "aerospace hist"/> Over 75% of the components of its aircraft, including [[Composite material|composite]] (carbon fibre and glass fibre reinforced polymer) elements, are manufactured in-house at the firm's facility located at the Mindelheim-Mattsies Airfield in [[Tussenhausen]]-Mattsies, Bavaria.{{Citation needed|date=January 2020}}

==History== ===Early activities=== The company was founded as Grob Aerospace during 1971 by Dr. '''Burkhart Grob''' (26 March 1926 - 20 May 2016).<ref name = "aerospace hist"/> Dr. Grob had been a qualified pilot as well as a mechanical engineer who ran a business producing machine [[Machine tool|tooling]] prior to creating the company; he had been inspired to produce his own [[Glider (sailplane)|glider]] after being informed of the lengthy production time involved in glider production at the time, convinced that it could be done better. Accordingly, Grob Aerospace had been founded with the vision of producing full-[[composite material|composite]] gliders that would be highly cost-competitive while facilitating a high rate of construction.<ref name = "aerospace hist">{{cite web |url = https://aero-space.eu/2019/02/20/the-breakthrough-grob-120tp-trainer/ |title = The breakthrough Grob 120TP trainer |publisher = aero-space.eu |date = 20 February 2019}}</ref>

At the onset of operations, Grob Aerospace was involved in the production of gliders, having quickly secured [[subcontractor|subcontracting]] work from the existing German manufacturer [[Schempp-Hirth]] to build the firm's [[Schempp-Hirth Standard Cirrus|Standard Cirrus]] glider [[licensed production|under licence]]. In excess of 200 Standard Cirruses were produced by Grob, the initial example being constructed at its machining workshop in [[Mindelheim]].<ref name = "aerospace hist"/> As the firm's production capacity expanded, Grob Aerospace relocated its operational base to a larger facility at the newly established Tussenhausen-Mattsies airfield.<ref name = "aerospace hist"/>

In 1974, Grob began to pursue independent glider production, harnessing its accumulated experience with composite construction. Instead of producing gliders that directly competed with the larger established manufacturers, the company differentiated its product by orientating itself towards the club market and adopting competitive pricing for its new product, the [[Grob G102 Astir|G-102 Astir]], the first Grob-designed glider.<ref name = "aerospace hist"/> During its long production life, over a thousand examples of the type would be produced. The G-102 was quickly followed by the larger two-seat [[Grob G103|G 103 Twin Astir]] line of sailplanes.{{Citation needed|date=January 2020}}

===Powered aircraft=== During the late 1970s, Grob also branched out into motorised aircraft, developing the [[Grob G 109|G 109]].<ref name = "aerospace hist"/> First flown on 14 March 1980,<ref>Hardy 1982, p. 155.</ref> it was the world's first production all-composite [[motor glider]] upon receiving its [[type certification]] from the [[Federal Aviation Administration]] (FAA) in 1981.<ref>[http://www.grob-aerospace.net/company/legacy/motorgliders/g-109b.html "G-109b."] ''Grob Aerospace'', Retrieved: 23 August 2008.</ref> In addition to widespread civilian use of the type, perhaps the most prominent operator of the G 109 was the [[Royal Air Force]], who adopted it for their [[Volunteer Gliding Squadrons]] (VGS) to train Air Cadets through the Gliding Induction and Gliding Scholarship courses up until 5 May 2018; in RAF service, the Grob 109B was designated ''Vigilant T1''.<ref name=RAF>{{cite web |url=http://www.raf.mod.uk/equipment/vigilantt1.cfm |work=RAF |title=Royal Air Force Equipment |accessdate=13 December 2009 |archive-url=https://web.archive.org/web/20170703051042/https://www.raf.mod.uk/equipment/Vigilantt1.cfm |archive-date=3 July 2017 |url-status=dead}}</ref>

The G 109 was only the start of Grob Aerospace's motorised aircraft lineup. It was followed by the larger [[Grob G 115|G 115]], an all-composite two-seat aerobatic monoplane, which received certification from the FAA during 1987.<ref name = "aerospace hist"/> Not all of the firm's designs were taken forward into production; the [[Grob GF 200|GF 200]], a relatively unorthodox [[business aircraft]], flew during the early 1990s but never progressed beyond test flights. The G160 Ranger, another business aircraft somewhat similar to the [[Pilatus PC12]], similarly did not enter production.<ref name = "aerospace hist"/> During 1996, Grob Aerospace decided to end production of gliders in favour of concentrating its manufacturing base on its powered aircraft instead.{{Citation needed|date=January 2020}}

During the 1980s, Grob Aerospace partnered with American defense firm [[E-Systems]] and engine manufacturer [[Garrett AiResearch|Garrett]] to develop the [[Grob G 520|G 520]], otherwise known as [[Egrett]]/''STRATO 1'', a specialised high-altitude aircraft.<ref name="Brasseys96 p172">Taylor 1996, p. 172.</ref> First flown on 24 June 1987, the type soon established five world records.<ref>G 520 – Records http://grob-aircraft.com/index.php/records.html</ref><ref>{{cite web |author=Staff |url=http://www.fai.org/fai-record-file/?recordId=1392 |title=Class C-1e (Landplanes: take off weight 3 000 to 6 000 kg) – Time to climb to a height of 15 000 m |publisher=[[Fédération Aéronautique Internationale]] |date=1 September 1988 |accessdate=29 August 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20140903101326/http://www.fai.org/fai-record-file/?recordId=1392 |archivedate=3 September 2014 }}</ref><ref>{{cite web |author=Staff |url=http://www.fai.org/fai-record-file/?recordId=1390 |title=Class C-1e (Landplanes: take off weight 3 000 to 6 000 kg) – Altitude in horizontal flight |publisher=[[Fédération Aéronautique Internationale]] |date=1 September 1988 |accessdate=29 August 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20140903101322/http://www.fai.org/fai-record-file/?recordId=1390 |archivedate=3 September 2014 }}</ref><!--error in FAI database?--><ref>{{cite web |author=Staff |url=http://www.fai.org/fai-record-file/?recordId=1388 |title=Class C-1e (Landplanes: take off weight 3 000 to 6 000 kg) – Altitude |publisher=[[Fédération Aéronautique Internationale]] |date=1 September 1988 |accessdate=29 August 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20140903101317/http://www.fai.org/fai-record-file/?recordId=1388 |archivedate=3 September 2014 }}</ref> During 1992, the [[German Air Force]] placed an order for a batch of nine ''EGRETT II'' aircraft, as well as for a single two-seat trainer and one of the demonstrators.<ref name="JAWA93p138-0">Lambert 1993, pp. 138–140.</ref> However, in February 1993, the German order was cancelled; this outcome was attributed to the [[peace dividend]] following the collapse of the Soviet Union and a decrease in military tensions.<ref name="JAWA93p138-0"/>

===SP<sup>n</sup> program=== During the mid-2000s, Grob Aerospace secretively embarked on a [[jet propulsion|jet-powered]] light aircraft programme, the [[Grob G180 SPn|Grob G180 SP<sup>n</sup>]]. In response to perceived market demand, this aircraft would possess both the [[STOL|short-field]] and cargo-carrying performance traditionally associated with [[turboprop]]-powered aircraft, as well as the extensive use of [[composite material]]s.<ref name = "first sales05"/> The aircraft's requirements were defined in close collaboration with the [[Switzerland|Swiss]]-based company ExecuJet Aviation Group. Following its public unveiling, it was initially referred to as the ''SPn Utility Jet''.<ref name = "first sales05"/> Plans for a family of aircraft based on the type were mooted at one stage.<ref>Sarsfield, Kate.

During November 2008, development of the G180 SPn was put on hold by the [[insolvency]] of Grob Aerospace.<ref name="FlightglobalDaherSocataTrialsSPnBusinessJetWithAViewToAdoption"/> Prior to the company's collapse, around 100 orders had been secured for the G180, which had a list price of €5.9 million ($8.7 million).<ref name="FlightglobalDaherSocataTrialsSPnBusinessJetWithAViewToAdoption"/><ref>Collins, Peter.

Niall Olver, Grob Aerospace's former CEO, was appointed by the creditor to find new investors to buy the assets of the G180 SPn with the aim of restarting the program by June 2009.

===2008 insolvency=== [[File:Logo Grob Aircraft H3.jpg|thumb|Initial Grob H3 logo]] [[File:Grob Aircraft logo 2020.png|thumb|Second iteration of Grob H3 logo]] On 18 August 2008, Grob Aerospace filed for insolvency. As a consequence, the firm suspended the majority of its activities, including all light-jet production; this shutdown raised questions over the timely delivery of [[Bombardier Aerospace]]'s [[Learjet 85]] prototypes, of which Grob had been contracted to produce. While efforts were made to seek new investors to rescue the company, most of Grob's employees were released on 3 November 2008.<ref name="AWST19Aug08">{{cite web |url = http://www.aviationweek.com/aw/generic/story_generic.jsp?channel=busav&id=news/GROB08198.xml&headline=Grob%20Aerospace%20Files%20For%20Insolvency |title = Grob Aerospace Files For Insolvency |accessdate = 31 October 2008 |last = Collogan |first = David |date = August 2008 |archive-url = https://web.archive.org/web/20120307145850/http://www.aviationweek.com/aw/generic/story_generic.jsp?channel=busav&id=news%2FGROB08198.xml&headline=Grob%20Aerospace%20Files%20For%20Insolvency |archive-date = 7 March 2012 |url-status = dead}}</ref><ref name="AOPA30Oct08">{{cite web |url = http://www.aopa.org/aircraft/articles/2008/081030industry.html |title = Credit crunch felt by GA manufacturers |accessdate = 31 October 2008 |last = Marsh |first = Alton K. |date = October 2008 |url-status = dead |archiveurl = https://web.archive.org/web/20081103063316/http://www.aopa.org/aircraft/articles/2008/081030industry.html |archivedate = 3 November 2008}}</ref> Niall Olver, Grob's chief executive officer, stated of the suspension:
