Ju 88A. What did the wooden bomb bay extension look like? How many bombs could be carried with it?
No wooden bombay extension for the A, you're speaking of the S.
Ju 88C. Which model was the most common for the (daytime) zerstörer role? What was the armament and performance of this model?
Ju 88C-6c Night-fighter (C was the most common model, however, I only have performance figures for the 6c which was a C-6 with the FuG 220 Lichtenstein SN-2 airborne interception radar to overcome the Window chaff used by the British to mask their bombers in a perviously impenetrable cloud of multiple radar echoes.)
Max speed 307 mph at 17k
Max range 1,230 miles
Max rate of climb at SL 1,772 fpm, climb to 19,685ft in 12 minutes 42 sec.
Armament:
3 MG151/20 with 360 rounds installed as one on the nose and two in the ventral tray, three MG 17 fixed forward firing machine guns with 2,800 rounds in the nose, two 20mm MG 151/20 obliquely upward and forward-firing cannon with 400 rounds in the central fuselage and one 13mm MG 131 trainable rearward-firing machine gun with 750 rounds in the cockpit rear.
Electronic and operational equipment:
Standard communication and navigation equipment, plus a Revi reflector gun sight and FuG 220 Lichtenstein SN-2 airborne interception radar.
The most common day fighter variant of the C was the C-7 which was armed with a 2x 20mm MG FF/M weapon tray. Probably had approximatly the same performance as the C6c.
Ju 88S. How many, and of which model were made and used?
S-1 S-2 S-3 saw service in very few numbers, I don't know how many were made but it was very few, the Ju 88 program was terminated in the summer of 44.
