Attack bomber[edit]

The Ju 88P was a specialized variant for ground attack and to function as a bomber destroyer, designed starting from 1942^[21] and produced in small numbers, using examples of the Bordkanone heavy calibre aviation autocannon series, which required the omission of the Bola undernose gondola for clearance. The prototype, derived from a standard Ju 88 A-4, was armed with a 7.5 cm anti-tank gun derived from the 7.5 cm PaK 40 installed in a large conformal gun pod under the fuselage. This was followed by a small batch of Ju 88 P-1, which standardized the solid sheet metal nose of the C version for all known examples of the P-series, and used the new 7.5 cm PaK 40L semi-automatic gun, also known as the Bordkanone BK 7,5,^[22] which was also meant for use in both the later Henschel Hs 129B-3 dedicated anti-armor aircraft, and a never-achieved production version of the He 177A-3/R5 ground-attack Flak-suppression Stalingradtyp field-improvised version. The Ju 88P-1 was produced in some 40 units, but with the massive cannon installation resulting in a slow and vulnerable aircraft,^[21] it was soon replaced by the Ju 88 P-2, featuring two Bordkanone 3.7 cm BK 3,7 guns, whose higher muzzle velocity proved useful against the Russian tanks in the Eastern Front. This aircraft was used by Erprobungskommando 25. The Ju 88 P-3 also used the twin BK 3,7 guns, and added further armor for the crew, and was delivered at one Staffel of the Nachtschlachtgruppen 1, 2, 4, 8 and 9 for night attacks in the Eastern Front, in northern Norway (NSGr 8) and Italy (NSGr 9).^[21] Finally, the Ju 88 P-4 mounted a smaller-volume ventral gun pod housing a 5 cm auto-loading Bordkanone BK 5 cannon (the same ordnance used for the field-improvised handful of Stalingradtyp He 177As created) and, in some cases, 6.5 cm solid propellant rockets.^[21]
