Bit of a discussion ensued last night in the MA re the rockets on a 109 and the use to which they were put in the war.
I suggested that they were anti-bomber and promised to look it up later to double check.
so heres a snippet from the net... this is also confirmed from my own library of books.
http://www.bf109.com/armament.htmlBf 109G-5Armament of this variant, consisted of the engine mounted 20mm MG 151 cannon and a pair of cowl-mounted 13mm MG 131 machine-guns, which had been standardized for all future G-series variants. The increase in the size of the cowling weaponry resulted in still another set of external bulges, this time over the MG 131 breech blocks and ammunition feed chutes which were larger than those of the MG 17's. One unique modification incorporated into the G-5 was the addition of a pair of underwing Wfr. Gr. 210mm mortar tubes for operations against Allied bomber streams. Designated as the Bf 109G-5/BR 21, the mortar tube concept was actually developed and flown initially on the Bf 109G-6 which preceded the G-5 variant in delivery to service units.
Check the above url for more information than you will EVER want to know about all variants of the 109...
To conclude... I assume that pilots may have used the rockets for ground attack.. may have... but they were apparently intended at least for anti-bomber use in the main.
