Peacemaker

The Kalinin K-7 was a real Russian Bomber designed in 1933 by WW-I aviator Konstatin Kalinin.

According to The World's Worst Aircraft - From Pioneering Failures to Multimillion Dollar Disasters by Jim Winchester, the plane had a wingspan greater than the American B-52.  

The bomber was 91 feet long and had seven 750HP engines, 6 on the leading edge of the wing and one at the rear of the fuselage.   The K-7 had a wingspan of nearly 174 feet and could fly at a maximum speed of 145 miles per hour.   The aircraft was also designed for other functions such as transporting VIP,  paratrooper and heavy cargo such as tanks.

According to the Kharkov State Aircraft Manufacturing Company (KSAMC) in the Ukraine, the K-7 actually first took to the skies on August 19, 1933 and her final flight was on November 23rd of that year.
