Ju 88G

Heavy Night Fighter

Junkers

Ju 88G

Producing in 1942 Ju-88C-6 has shown very high efficiency in a role of a night fighter. It was the first airplane of such type designed during development of heavy fighter Ju-88C. The installation of the additional equipment inevitably conducted to increase of weight of the machine and deterioration of flight performances, and as result - to reducing speed. All this has resulted in occurrence by spring of 1943 and the prototype following, considerably improved model of night fighter Ju-88 Ju-88G V1. This prototype formed by alteration bomber Ju-88R with the installation on it of a tail unit from Ju-188.

In total it has been made over 2800 night fighters Ju-88G in versions Ju-88G-1, G-4, G-6 and G 7, each of which had two - three more versions with various armament and radars of different types. These machines went into service since a summer of 1944.

Variants

Ju 88G Night fighter, new fuselage with A-series' ventral Bola (Bodenlafette) gondola omitted, tail section from Ju 188, aerodynamically improved conformal gun pod for a quartet of forward-firing 20 mm calibre, MG 151/20 autocannons below the former bomb bay.

Ju 88 G-1 BMW 801 radial engines with 1700 PS, FuG 220 Lichtenstein SN-2 radar

Ju 88 G-6 Junkers Jumo 213A inverted V12 engines with 1750 PS, used either FuG 220 Lichtenstein SN-2 90 MHz or FuG 218 Neptun 158/187 MHz frequency radar, either with the usual Hirschgeweih eight-dipole aerial setup or experimentally with the more aerodynamic Morgernstern tripled crossed-dipole aerials. Some very-late-war aircraft equipped with experimental FuG 240 Berlin cavity magnetron based 3 GHz radar, with dish antenna in bulbous solid nose. Optional with Schr├Ąge Musik upward firing guns with two 20 mm or 30 mm guns.

Ju 88 G-7 Identical to G-6, but with Jumo 213E high-altitude engines, planned for use with FuG 218/220 with Morgenstern array or FuG 240. The G-7 was also to be installed with wings from the Junkers Ju 188.

Ju 88G-3, 4 and 8 not produced.

Ju 88H Long-range photo-reconnaissance, fighter variants, based on the stretched Ju 88G-series fuselage.

Ju 88 H-1 Long-range maritime reconnaissance variant, equipped with a FuG 200 Hohentwiel radar and a trio of remotely controlled cameras in the aft fuselage.

Ju 88 H-2 Fighter variant intended to attack Allied long range convoy escort aircraft armed with six Forward firing MG 151/20.

Ju 88 H-3 Ultra-long-range maritime reconnaissance variant similar to H-1.

Ju 88 H-4 Destroyer variant.

Ju 88P Anti-tank and bomber destroyer variant with single Bordkanone series 75 mm (2.95 in), 50 mm (1.97 in), or twin 37 mm (1.46 in) calibre cannon in conformal ventral fuselage gun pod mount, which mandated removal of the Bola gondola under the cockpit section, conversion of A-series bomber. Produced in small series only, they were perceived as a failure for both anti-tank[54] and anti-bomber use.

Ju 88 P-1 Heavy-gun variant fitted with single 75 mm (2.95 in) Bordkanone BK 7,5 cannon in ventral gun pod. Appeared in mid-1942 in small numbers.
