It turned out that there was still no uniform configuration "2056D" achieved. According to the latest Lockheed construction documents, which apparently only the LAAO submitted, up to 60 SB's (Service Bulletins) were missing on the individual aircraft. There is an LAAO report from 14.10.1962. It was therefore decided that the affected 19 F-104G should be retrofitted again by staff of Heinkel from Speyer at Nörvenich. With the instruction of the BWB FS 173/51315 of 30.10.1962 this action was initiated. But for the reasons already mentioned, this work could not begin until January 1963. The following aircrafts were re-modified again: factory numbers: 2043, 2044, 2046 - 2049, 2053 - 2058, 2060 - 2066. 8 aircrafts were changed to such an extent that they received a new tactical code: 2049 - DA+253 to DA+232 2057 - DA+122 to DA+112 2058 - DA+254 to DA+234 2060 - DA+257 to DA+237 2061 - DA+258 to DA+240 2062 - DA+129 to DA+119 2063 - Da+259 to DA+239 2066 - DA+126 to DA+120 10 of these Project "19" aircraft took part in the "Category III" tests: 2043, 2044, 2046, 2047, 2048, 2053, 2054, 2055, 2056, 2057. "Category III" were tests of operational mission profiles and system tests from April until July 1963.
