Germany
The Uhu (english: Owl) is considered to be the finest night-fighter of Germany of World War 2. In 1940 Heinkel made a proposal to the german government for a twin-engine heavy fighter that could be adopted for torpedo bombing and/or for medium bomber duties. At first the government declined, insensitive to the excellent proposal, but had to change it's mind when the night bombing campaign of the RAF started picking up speed and accuracy. The result was that Heinkel was asked to redesign it's heavy fighter for a dedicated night-fighter type. Because the plans were already in an advanced stage, Heinkel could start building a prototype almost immediately, but ironically enough was set back considerably when an RAF bombing raid destroyed most of the completed drawings.
Even so, the work continued, and a heavy warplane with a fully retractable tricycle landing gear emerged. It had a fully glazed cockpit for two crewmembers, each seated on an ejector seat that operated on compressed air. These ejector seat were the first in service in the world. The powerplants were inverted-Vee's, but had an anular radiator in front of them giving a 'Radial-engine' look.

Here is a quick overview of all different versions, without the full technical specifications:
| Different versions of the Heinkel He 219 Uhu |
|---|
| Heinkel 219A-0 Uhu | Initially 10 prototypes were built, of which 7 were designated He 219A-0 as preproduction aircraft. All versions were fitted with the FuG 212 Lichtenstein C-1 intercept radar. There were two version, only slightly differing in armament. Rüstsätze (field conversion sets):

| Heinkel 219A-2 Uhu | Initially the next version would have been the He 219A-1, powered with 2 × Daimler-Benz DB 603, fitted with the GM-1 nitrous-oxide powerboost, but this was canceled. Thus the first production batch was the He 219A-2, powered by 2 × Daimler Benz DB 603A. One of the prototypes had paved the way for the Shräge Musik installation. This cannon set-up pointed up and forward, making it possible for the Uhu to fly it's initial course without having to pull-up and slow down in order to fire at the target. Shräge Musik had another advantage, namely it was aimed at the relatively unprotected belly of the bombers. Also, the night-fighter was hard to spot, and it became even harder to spot when the background wasn't a clear night sky. Rüstsätze (field conversion sets):

| Heinkel 219A-5 Uhu | The He 219A-3 and He 219A-4 were uncompleted projects for a three-seat bomber and three-seat reconnaissance bomber. So the next version was the He 219A-5. This was an improved night-fighter, based on the He 219A-2. Rüstsätze (field conversion sets):

| Heinkel 219A-6 Uhu | The effectiveness of the De Havilland Mosquito worried the Germans, for it was a very fast and small aircraft that could also operate at night, making it very hard to catch them. In order to deal with them Heinkel built the He 219A-6. The He 219A-6 was a conversion from the He 219A-2/R1, powered by 2 × Daimler-Benz 603L, rated at 1,750 hp (1.305 kW) each, and fitted with the GM-1 nitrous-oxide powerboost. Further, this versin had no Shräge Musik, and no armor, to increase performance. It entered service in August 1944. Number converted: unknown | ||||||||||||
| Heinkel 219A-7 Uhu | This was the last production version, and had the biggest number of Rüstsätze, to deal with a variety of armament and engine options. Rüstsätze (field conversion sets):
Number built: unknown out of a total of about 288 |
Remarks:
The Uhu had exceptional capabilities, and was an outstanding night fighter. Strangely enough, the German government ordered only a small number, probably because of political reasons. Even though the Heinkel company was not liked by the German leadership and orders were minimal, Heinkel decided to build on contradicting government orders.
In Venlo, The Netherlands, the first unit was formed: I/NJG 1. It was a Heinkel He 219A-0/R2 that in the night of 11/12 June 1943 scored it's first kill. Actually, it scored 5 kills against British bombers in a timespan of 30 minutes! During the first 6 sorties of He 219A-0's 20 British bombers were claimed, including 6 De Havilland Mosquitoes.
