After the September 1943 Armistice of Cassibile with Italy, Romania became the second Axis Power in Europe. The Romanians shared in the spoils of Operation Achse, Regia Marina's 5 CB-class midget submarines in the Black Sea being transferred to the Romanian Navy. Romania also captured 496 Italians, mostly naval personnel (2 of them later died). Before the month was out, Germany had agreed to systematically supply the Romanian Army with German military vehicles, via the Olivenbaum I-III and Quittenbaum I programs. Deliveries started in November 1943, and by August 1944, Germany had supplied Romania with 10 times more armored vehicles (Panzer III, Panzer IV and Sturmgeschütz III) than during the entire pre-Cassibile period. Having acquired the license to produce the Messerschmitt Bf 109, Romania planned to assemble 75 from German parts. Deliveries began in May 1944, but only 6 were completed before Romania left the Axis in August 1944. Eleven more were completed by the end of the war with the remaining 58 completed after the war. In 1944, Romania had also gained access to certain Wunderwaffen, such as the Werfer-Granate 21. The first Romanian-made Fiesler Storch was completed in October 1943, followed by 9 more by May 1944. From March 1944, Germany also contributed to the design and construction of the M-05 and M-06 prototypes of the Mareșal tank destroyer: Alkett contributed to the Romanian design team and Telefunken radios along with Böhler armor were provided. The 75 mm Reșița gun (production started at the end of 1943) used the projectile chamber of the German Pak 40. Technology transfers between the two countries were not necessarily one-way, however. On 6 January 1944, Antonescu showed Hitler the plans of the M-04 prototype of the Mareșal tank destroyer. In May 1944, Lieutenant-Colonel Ventz from the Waffenamt acknowledged that the Hetzer had followed the Romanian design. German-led Army Group South Ukraine could not take major operational decisions without securing Ion Antonescu's approval, even as late as 22 August 1944 (the day before he was dismissed). An entire German army (the 6th) came under Romanian command in May 1944, when it became part of Romanian general Petre Dumitrescu's Armeegruppe. For the first time in the war, German commanders came under the actual (rather than nominal) command of their foreign allies. This Romanian-led army group had 24 divisions of which 17 were German.
