B6313 was completed by the Sopwith Aviation Co. Ltd of Kingston-on-Thames and delivered to the Aeroplane Acceptance Park at Kenley on 11 September 1917. On 24 September B6313 went to No.28 Sqn RFC based at Yatesbury. No.28 Sqn was getting ready to go to France and on 2 October a new 'C' Flight commander joined the squadron. William George Barker and B6313 were to be together for the next year. During the year of operational flying B6313 had amassed 404 hours, 10 minutes of flying time, of which Barker put in 379 hours 25 minutes. With an unprecedented 46 claims in one plane flown by the same pilot, B6313 has been called the single most-successful fighter aircraft in the history of the RAF.
