Problems with its Hispano-Suiza engine, particularly the geared-output H-S 8B-powered early versions, meant that there was a chronic shortage of the type until well into 1918. Thus, while the first examples had reached the Western Front before the Camel, there were fewer squadrons equipped with the S.E.5 than with the Sopwith fighter. Together with the Camel, the S.E.5 was instrumental in regaining allied air superiority in mid-1917 and maintaining it for the rest of the war, ensuring there was no repetition of "

that, while providing excellent performance, was initially underdeveloped and unreliable. The first of three prototypes flew on 22 November 1916. The first two prototypes were lost in crashes (the first killing the chief test pilot at the Royal Aircraft Factory, Major Frank Goodden, on 28 January 1917) due to a weakness in their wing design. The third prototype underwent modification before production commenced; the S.E.5 was known in service as an exceptionally strong aircraft which could be dived at very high speed – the squarer wings also gave much improved lateral control at low airspeeds.Hare 2013, p. 46.

The S.E.5b was a variant of the S.E.5 with a streamlined nose and upper and lower wings of different span and chord. The single example, a converted S.E.5a, first flew in early April 1918. It had a spinner on the propeller and a retractable underslung radiator. Its performance was little better than the S.E.5a, with the extra drag of the big upper wing offsetting gains from the more streamlined fuselage. The S.E.5b was not considered for production. In January 1919, it was tested with standard S.E.5a wings and in this form survived as a research aircraft into the early twenties.Hare 2013, pp. 98-100.

, the S.E.5's cockpit was "the best of the bunch from the era". It was set amidships, making it difficult to see over the long front fuselage, but otherwise visibility was good. Individual in-service S.E.5s would often receive customisations and user-specified tweaks at the request of their pilots. Popular changes included reducing the dihedral of the wings in order to increase its manoeuvrability and the removal of the head fairing to increase the pilot's visibility to the rear.

pilot and former RFC mechanic, was famous for his prolific fine-tuning of his aircraft in order to produce improved performance from it; McCudden was able to increase the top speed by 9 mph and to raise the service ceiling from the standard 17,000 ft to 20,000 ft. His adaptions included replacing the standard pistons with high compression versions, shortening the exhaust (saving weight and improving exhaust scavenging), and changes to mixture, ignition and other engine settings as well as fitting a salvaged German propeller spinner (which he himself credited as gaining 3 mph alone). Aviation authors Donald Nijboer and Dan Patterson describe the S.E.5 as "arguably the best British-built fighter of World War I".

Operational history

In March 1917, the S.E.5 entered service with No. 56 Squadron RFC, although the squadron did not deploy to the Western Front until the following month.Jackson 2007, p. 11. Everyone was suspicious of the large "greenhouse" windscreens fitted to the first production models. These were designed to protect the pilot in his unusually high seating position, which was in turn intended to improve vision over the upper wing. The squadron did not fly its first patrol with the S.E.5 until 22 April,Bruce 1953, p. 87. by which time, on the insistence of Major Blomfield, 56 squadron's commanding officer, all aircraft had been fitted with small rectangular screens of conventional design. The problem of the high seating position was solved by simply lowering it, pilots in any case preferring a more conventional (and comfortable) seating position. No complaints seem to have been made about the view from the cockpit; in fact, this was often cited as one of the strong points of the type. While pilots, some of whom were initially disappointed with the S.E.5, quickly came to appreciate its strength and fine flying qualities, it was popularly judged to have been underpowered; this failing was addressed by the introduction of the more powerful S.E.5a. In June 1917, the S.E.5a entered service and quickly began to replace the S.E.5. At this time 56 Squadron was still the only unit flying the new fighter; in fact it was the only operational unit to be fully equipped with the initial 150 hp S.E.5 – all other S.E.5 squadrons officially used the 200 hp S.E.5a from the outset – although a few S.E.5s were issued to other squadrons due to an acute shortage of the S.E.5a. Deliveries of the S.E.5a suffered from delays due to a shortage of available engines with which to power the type. Due to the shortage of aircraft, there was a very slow initial build-up of new S.E.5a squadrons, which lasted well into 1918. Once the

-powered model became plentiful, many more units were re-equipped with the type. By the end of the war, the S.E.5a was employed by a total of 21

Sholto Douglas who commanded No. 84 Squadron RFC which was initially equipped with the S.E.5a, listed the type's qualities as being: "Comfortable, with a good all-round view, retaining its performance and manoeuvrability at high level, steady and quick to gather speed in the dive, capable of a very fine zoom, useful in both offence and defence, strong in design and construction, ndpossessing a reliable engine".
