Editing IAR 80 (section)

===IAR&nbsp;80===
Production of the IAR&nbsp;80 started immediately, although the armament proved to be a serious problem. The prototype had mounted only two [[Belgium|Belgian]]-made [[Fabrique Nationale]] 7.92&nbsp;mm [[machine guns]], a licensed modification of the [[M1919 Browning machine gun|Browning .30 cal]]. This armament was not heavy enough against modern aircraft, and the production model was expected to mount six. The [[German invasion of Belgium (1940)|German invasion of Belgium]] in 1940 suspended the supply from FN, and there was no suitable replacement.<ref>[http://www.century-of-flight.net/Aviation%20history/photo_albums/timeline/ww2/2/IAR%2080%20&%2081.htm "IAR 80 & 81."] {{Webarchive|url=https://web.archive.org/web/20161112061646/http://www.century-of-flight.net/Aviation%20history/photo_albums/timeline/ww2/2/IAR%2080%20%26%2081.htm |date=2016-11-12 }} ''century-of-flight.net'', 2003.

The first five aircraft were ready to be delivered in November, with the first batch of 20 being delivered by the middle of February 1941. By April, all 50 initially ordered IAR&nbsp;80s were delivered.<ref name="productia"/> The armament supply remained inadequate so production models only carried four guns.

The initial batch of fighters was well received by the Romanian pilots, but they found the aircraft underpowered and lacking firepower. In order to address this, the aircraft mounted the {{convert|960|hp|kW|abbr=on}} IAR&nbsp;K14&nbsp;IVc32 engine in the 21st through 50th examples, but the firepower concern could not be resolved at the time.
