Preparations were carried out in 1940 to produce the first batch of 10 aircraft at Factory No.21 in Gorki, engaged in manufacturing the I-16. However, their production was extremely slow, without much attention of the aviation authorities, with the first 10 aircraft taking more than eight months. One of the reasons for this was that the local OKB led by M.M. Pashinin was designing their own I-16 based fighter, the Pashinin I-21 and factory management had devoted all of their resources to the hometown favorite, with only six brand new engineers assigned to production of the I-180. While this was being investigated, the third prototype I-180-3, powered by a more powerful M-88R engine and fitted with a stressed skin wing (replacing the I-16 type wing structure of the previous prototypes) was completed, flying on 10 February 1940. It was armed with two 12.7 mm Berezin BS
