The Soviet Polikarpov design bureau is perhaps best known for the I-16 fighter, the worlds first monoplane fighter to have a retractable undercarriage. This aircraft is covered in Volume 3 of the Red Star series. This book explores the development of Polikarpovs fighting biplanes from the 2I-N1 to his first aircraft to see production; to the I-3 and the I-5 created while the designer was in prison. A detailed account of the combat role of these aircrafts is given as are structural descriptions. The book also includes details of the ill-starred I-190 which was to have superceded the Chaika and of privately owned I-15bis and I-153s which have been restored to airworthy condition.
