Through most of the Second World War and the 1950s No. 219 Squadron of the Royal Air Force operated as a night fighter air defence squadron. Three commanders of the squadron went on to be Chiefs of the Air Staff, two of the RAF and one of the Royal Pakistani Air Force.

It reformed in October 1939, shortly after the outbreak of the Second World War, operating Bristol Blenheims from RAF Catterick. Whilst it was intended to carry out shipping protection missions, it began to be used as a night fighter unit after becoming fully operational in February 1940; in October, it was moved to RAF Redhill, near London, and converted to the Bristol Beaufighter.

In December 1940, it moved to RAF Tangmere in Sussex, continuing in its operational role.

It moved back to north England in mid 1942, to RAF Acklington and later RAF Scorton; in May 1943, the squadron was transferred to North Africa, where it was dispersed between various ports to provide night fighter defence. In September 1943 it operated a number of aircraft from Sicily, but moved back to the UK in January 1944 to join the newly forming Second Tactical Air Force in preparation for the invasion of Normandy. It re-equipped with de Havilland Mosquito night fighters, first Mk. 17 and later Mk. 30 models, and flew intruder missions over north-western Europe from RAF Woodvale, RAF Honiley, RAF Bradwell Bay and RAF Hunsdon. It moved to bases in France in October 1944, returning to the UK after the end of hostilities in August 1945, and was disbanded in September 1946.

Bristol Blenheim - nightfighters

.https://www.youtube.com/watch?v=hipWoINtJX0 > . 
A night fighter (also known as all-weather fighter or all-weather interceptor for a period of time post-World War II) is a fighter aircraft adapted for use at night or in other times of bad visibility.

Bristol Blenheim
In the German night-bombing raid on London on 18 June 1940, Blenheims accounted for five German bombers, thus proving that they were better-suited for night fighting. In July, No. 600 Squadron, by then based at RAF Manston, had some of its Mk IFs equipped with AI Mk III radar. With this radar equipment, a Blenheim from the Fighter Interception Unit (FIU) at RAF Ford achieved the first success on the night of 2–3 July 1940, accounting for a Dornier Do 17 bomber. More successes came, and before long the Blenheim proved itself invaluable as a night fighter. Gradually, with the introduction of the Bristol Beaufighter in 1940–1941, the Blenheim was supplanted by its faster, better-armed descendant.

Night Fighter Aircraft
http://www.militaryfactory.com/aircraft/nightfighter-aircraft.asp

Night fighters began to be used in World War I and included types that were specifically modified to operate at night.

During World War II, night fighters were either purpose-built or day fighters modified to be effective night fighting combat aircraft, often employing radar or other systems for providing some sort of detection capability in low visibility. Many WW II night fighters also included instrument landing systems for landing at night as turning on the runway lights made runways into an easy target for opposing intruders.

Avionics systems were greatly miniaturized over time allowing the addition of radar altimeter, terrain-following radar, improved instrument landing system (ILS), microwave landing system (MLS), Doppler weather radar, LORAN receivers, GEE, tactical air navigation system (TACAN), inertial navigation system (INS), GPS, and GNSS in aircraft. The addition of greatly improved landing and navigation equipment combined with radar led to the use of the term all-weather fighter or all-weather fighter attack, depending on the aircraft capabilities. The use of the term night fighter gradually faded away as a result of these improvements making the vast majority of fighters capable of night operation.

The Nazis invaded Poland on 1 September 1939, and by this time, the RAF were well advanced with plans to build a radar – then called 'RDF' in Britain – equipped night-fighter fleet. The Airborne Interception Mk. II radar (AI Mk. II) was being fit experimentally to a small number of Bristol Blenheim aircraft, having been selected for this role as its fuselage was sufficiently roomy to accommodate the additional crew member and radar apparatus; the first prototype system went into service in November 1939, long before the opening of major British operations. These early systems had significant practical problems, and while work was underway to correct these flaw, by the time the Blitz opened in August 1940, the night fighter fleet was still in its infancy.

Through this period, the RAF experimented with many other aircraft and interception methods in an effort to get a working night fighter force. One attempt to make up for the small number of working radars was to fit an AI to a Douglas Havoc bomber which also carried a searchlight in its nose. These Turbinlite aircraft were intended to find the targets and illuminate them with the searchlight, allowing Hurricanes adapted for night flying to shoot them down visually. This proved almost impossible to arrange in practice, and the Cat Eye fighters had little luck during the closing months of 1940. The Turbinlite squadrons were disbanded in early 1943.

By early 1941, the first examples of a production-quality radar, AI Mk. IV, were beginning to arrive. This coincided with the arrival of the Beaufighter, which offered significantly higher performance than the pre-war Blenheims; it was the highest performance aircraft capable of carrying the bulky early airborne interception radars used for night fighter operations, and quickly became invaluable as a night fighter. Over the next few months, more and more Beaufighters arrived and the success of the night fighters roughly doubled every month until May '41, when the Luftwaffe ended their bombing efforts. Although night bombing never ended, its intensity was greatly decreased, giving the RAF time to introduce the AI Mk. VIII radar working in the microwave band, and the de Havilland Mosquito to mount it. This combination remained the premier night fighter until the end of the war.

As the German effort wound down, the RAF's own bombing campaign was growing. The Mosquitos had little to do over the UK, so a number of squadrons were formed within No. 100 Group RAF and fit with special systems, such as Perfectos and Serrate, for homing-in on German night fighters. The British also experimented with mounting pilot-operated AI Mark 6 radar sets in single-seat fighters, and the Hurricane II C(NF), a dozen of which were produced in 1942, became the first radar-equipped, single-seat night fighter in the world. It served with 245 and 247 Squadrons briefly and unsuccessfully before being sent to India to 176 Squadron, with which it served until the end of 1943. A similarly radar-equipped Hawker Typhoon was also developed, but no production followed.

Boyington Proves His F4U Corsair Has What It Takes > .
On September 16, 1943, Gregory “Pappy” Boyington returned to base having successfully shot down five Japanese “Zeroes.” It was proof that his F4U Corsair fighter plane could more than hold its own in the Pacific.

Dornier Do. 335

One of WWII's strangest aircraft, the Dornier 335 was also one of its best.

The Dornier Do 335 Pfeil ("Arrow") was a World War II heavy fighter built by the Dornier company. The two-seater trainer version was called Ameisenbär ("anteater"). The Pfeil's performance was much better than other twin-engine designs due to its unique push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines. It was Nazi Germany's fastest piston-engined aircraft of World War II. The Luftwaffe was desperate to get the design into operational use, but delays in engine deliveries meant that only a handful were delivered before the war ended.
  • Maximum speed: 763 km (474 mph, 412 kn) at 6,500 m (21,300 ft)
  • A-6 690 km/h (430 mph; 370 kn) at 5,300 m (17,400 ft)
  • Cruise speed: 685 km (426 mph, 370 kn) at 7,200 m (23,600 ft)
  • Economical cruise speed: 452 km/h (281 mph; 244 kn) at 6,000 m (20,000 ft)
