On 12 August 1940, the first production Beaufighter was delivered to
RAF Tangmere for trials with the
Fighter Interception Unit. On 2 September 1940,
25 Squadron,
29 Squadron,
219 Squadron, and
604 Squadron became the first operational squadrons to receive production aircraft, each squadron received a single Beaufighter that day to begin the transition from their existing
Blenheim IF aircraft.[SUP]

[13][/SUP] The reequipping and conversion training process took several months to complete; on the night of 17/18 September 1940, Beaufighters of No. 29 Squadron conducted their first operational night patrol, conducting an uneventful sortie, the first operational daylight flight was performed on the following day.[SUP]
[28][/SUP] On 25 October 1940, the type's first confirmed kill, a

Initial production deliveries of the Beaufighter lacked the radar units to perform night fighter operations; these were progressively installed retroactively by
No. 32. MU based at
RAF St Athan during late 1940.[SUP]
[11][/SUP] On the night of 19/20 November 1940, the first kill by a radar-equipped Beaufighter was performed, shooting down a
Junkers Ju 88.[SUP]

Luftwaffe. By March 1941, half of the 22 German aircraft claimed by British fighters were by Beaufighters; during the night of 19/20 May 1941, during one air raid upon London, a total of 24 aircraft were shot down by fighters against two that were downed by
anti-aircraft ground fire.[SUP]

In late April 1941, the first two
Beaufighter Mk II aircraft,
R2277 and
R2278, were delivered to
600 and 604 Squadrons; the former squadron being the first to receive the type in quantity in the following month.[SUP]
[29][/SUP] In addition to its service with the RAF, the Mk II variant was supplied to the
Fleet Air Arm of the
Royal Navy as well.[SUP]
[15][/SUP] A night-fighter
Beaufighter Mk VIF was supplied to squadrons in March 1942, equipped with
AI Mark VIII radar. The night fighter role was the first role in which the Beaufighter proved its merits, but went on to perform in various other capacities during the wa
