Manufacturing of the Gladiator was started at Gloster's Hucclecote facility. Production of the initial batch was performed simultaneously, leading to many aircraft being completed around the same time. On 16 February 1937, K6129, the first production Gladiator, was formally accepted by the RAF; on 4 March 1937, K6151, the last aircraft of the initial batch, was delivered.[5] In September 1935, a follow-up order of 180 aircraft was also received from the Air Ministry;[10] this order had the proviso that all aircraft had to be delivered prior to the end of 1937.[5]
