AJagdstaffel (pluralJagdstaffeln, abbreviated toJasta) was afighterStaffel (squadron) of theGerman ImperialLuftstreitkräfte duringWorld War I.
Before April 1916,Die Fliegertruppen des deutschen Kaiserreiches, which had been established in 1912 as the aviation service of theImperial German Army, was largely organised in small general purpose units (Feldfliegerabteilungen, FFA Field Flyer Detachments). The first specialist bombing and close support units began forming during 1915. TheFFA were subordinate to the Army command to which they were attached.[1]
By the end of the spring of 1915, the first German fighter aircraft were being issued in small numbers to theFFA. At this period their function was seen almost entirely as "protection" for the reconnaissance missions which were the primary duty of theFliegertruppe. Pilots likeKurt Wintgens,Max Immelmann andOswald Boelcke pioneered the aggressive use of the earlyFokker Eindecker fighters but it was to be almost a year before the first specialist fighter units joined theLuftstreitkräfte.
In February 1916, the first step towards fighter-only units began, with the establishment byInspektor-Major Friedrich Stempel of units described variously asFokkerstaffeln orKampfeinsitzer Kommando (KEK, single-seat battle unit) formations. Fighter aircraft already in service and their pilots were detached from the general-purposeFFA units and brought together in pairs and quartets at important locations. Such units were formed atVaux,Avillers,Jametz,Cunel and other places along the Western Front asLuftwachtdienst (aerial guard service) units, consisting only of fighters.[2] This process was by no means universally welcomed, nor did it bring immediate success. By April 1916, theair superiority established by the Eindecker pilots in theFokker Scourge had long gone and the Eindeckers were giving way to theFokker andHalberstadt D-series biplane fighters.
In the aftermath of theBattle of Verdun, during which the German side lost theair superiority built up over the Western Front during the so-calledFokker Scourge and as a result of the superior performance of theRoyal Flying Corps (RFC) and the FrenchAéronautique Militaire during theBattle of the Somme, the German flying service was reorganised, greatly expanded and renamed theDeutschen Luftstreitkräfte (German Air Service) reflecting a far greater degree of autonomy, although it remained an integral part of the army and acquired a far greater number and variety of specialist units, includingJagdstaffeln (hunting squadrons), the first German single-seater fighter units.[3]
A target was set to establish 37 new squadrons in the next 12 months, equipped with up-to-date single-seat fighters and manned by specially selected and trained pilots, to counter the successes of the Allied fighter squadrons operated by the RFC and the FrenchAéronautique Militaire. Boelcke, the leading fighter pilot of the day, was called on to organise the manning, equipment and training ofJasta 2 which was to become the model for these new squadrons. InitiallyJasta 2 was equipped with a motley collection of fighters, including early Fokker and Halberstadt"D" types. In September, the squadron began to receive the firstAlbatros D.I fighters, that created the German air superiority of the first half of 1917. Boelcke was killed in an aerial collision on 28 October but his tactics, especially formation flying and a combination of aggression and prudence known as theDicta Boelcke, remained the core ofJagdstaffel practice in theLuftstreitkräfte fighter arm for the rest of the war. Several pilots ofJasta 2 trained by Boelcke, became fighter leaders, notablyManfred von Richthofen.[4]
By April 1917, theJagdstaffeln had established air superiority on the Western Front (known since asBloody April and still regarded as the most disastrous period in the history of British military aviation). This ascendancy was not to last, as new allied fighters (most famously, theS.E.5a, theSopwith Camel and theSPAD S.XIII) were already starting to come into service, all of which more than matched the last of the Albatros fighters to see squadron service, the disappointingD.V/D.Va.[5]
TheJagdstaffeln concentrated on hindering the work of the Allied two-seater corps reconnaissance and bombing squadrons. Offensive incursions by fighters any distance behind Allied lines were avoided, as were mass confrontations with large allied fighter formations, on the grounds that such operations risked attrition that theLuftstreitkräfte could ill-afford.[6][a]
Publicity for successful German fighter pilots and the cult of theAir ace rapidly established the status of their squadrons as elite units, which became associated with the kingdoms of the German Empire. MostJagdstaffeln (eventually about 67 of them) were considered to be Prussian while other such units were associated with Bavaria, Saxony and Württemberg. The BavarianJagdstaffeln in particular were associated for organisational and supply purposes with the (theoretically independent) Bavarian army, which did not add to overall efficiency in these departments.[8]
To obtain a local and temporary air superiority, larger fighter units were established, composed of severalJagdstaffeln, known asJagdgeschwader andJagdgruppen (Fighter Wing and Fighter Group). These units were moved from one section of the front to another as the tactical situation demanded. The most famous of these units wasJagdgeschwader 1 composed ofJagdstaffeln 4, 6, 10 and 11, commanded by Richthofen until he was killed, many of which flew the supremely manoeuvrableFokker Dr.I triplane from the autumn of 1917.[9] By March 1918, there were 80Jagdstaffeln in theLuftstreitkräfte, most of them equipped with Albatros D.Vs. A long overdue re-equipment with new types began, most notably theFokker D.VII, which for the first time since mid-1917, gave theJagdstaffeln equipment that matched their opponents'.
German aircraft left the factory in a standard finish, although this differed from one manufacturer to another. Clear varnish on fabric and wooden surfaces had changed by 1916 to various camouflage schemes. In theJagdstaffeln this gave way to a riot of colour, as pilots repainted their machines as they pleased. In January 1917, when he took overJasta 11, Richthofen celebrated by painting his Albatros red and the squadron followed suit, painting at least part of their machines red. OtherJagdstaffeln soon adopted the fashion until few fighters flew in the manufacturers' finish, their fuselages in particular at least sporting the pilot's monogram or perhaps his favourite colour(s), even if the wings (as was often the case) remained in camouflage. A squadron theme was sometimes followed, with machines decorated in similar colours or with similar motifs but generally personal preference seems to have been prevalent.[10] More than one pilot (on both sides) recorded that the contrast with the plain khaki of RFC fighters was helpful in rapidly distinguishing friend from foe in the hurly-burly of a dogfight and might have aided the accreditation of air victories claimed by individual German pilots.
