| 释义 |
Project Barbara was a project by the Kriegsmarine, which was undertaken during World War II, to improve the anti-aircraft capabilities of its ships. HistoryDuring this project, numerous {{cvt|20|mm|3}} anti-aircraft guns were to be added to all surface ships, including destroyers. In 1944 a sub-project was set up, to give small ships, including destroyers, 3.7 cm Flak M42 anti-aircraft guns. In mid–1941, the decision was made to upgrade existing {{cvt|37|mm|3}} guns to either {{cvt|40|mm|3}} or {{cvt|50|mm|3}} guns. The decision was made to use the 5.5 cm Flak Gerät 58 anti-aircraft guns, which were in development, and which were to be able to fire {{cvt|2|kg}} at a rate of either 120 or 150 rounds per minute, and to be capable of single shot fire. It was to be gas operated and able to work on a triaxial or quad-axial mount. This project never reached fruition, and no guns of the type were ever mounted. Later on, the decision was made to replace all {{cvt|20|mm|3}} with {{cvt|30|mm|3}} guns, but this too was not completed.{{sfn|Friedman|2014|p=281}} ReferencesBibliography
