During the course of 1942 and 1943 JG 2 and JG 26 carried out "Jabo" operations in towns and coastal targets in England, and occasionally bombed London. At the beginning of 1943, SKG 10 had taken over these operations as JG 2 and JG 26 could no longer be spared for offensive operations. JG 26 were at a distinct disadvantage in comparison to JG 2 in "Jabo" operations. Its pilots had little experience and no dedicated "staffeln" when attacks began in earnest in March 1942. Those deemed unsuitable as fighter pilots, undisciplined or who had clashed with commanders were the first sent into 10. and 13. "Staffeln" which were to operate as fighter-bombers. The lack of training and enthusiasm in the 17 "tip and run" attacks contributed to the ineffectiveness on 10. "Staffel". The imbalance of the raids was noticed by the British; Kent and Sussex being 10./JG 26s area of operations, while the experienced 13./JG 2 operated over Hampshire 49 times, though 10./JG 26s region was more heavily defended. The first certain fighter-bomber mission occurred on 7 March 1942. From 19 April to 18 June German records indicate 32 Jabo missions were flown by Bf 109 F-4s against a variety of targets. Fighter-bomber attacks by 10 "Staffel" lasted up until 5 February 1943. Five JG 26 Fw 190s were lost this way on 21 January 1943.
