The Tupolev ANT-25 was a Soviet long-range experimental aircraft which was also tried as a bomber. First constructed in 1933, it was used by the Soviet Union for a number of record-breaking flights.

Pavel Osipovich Sukhoi was a Soviet aerospace engineer and aircraft designer known as the founder of the Sukhoi Design Bureau. Sukhoi designed military aircraft with Tupolev and Sukhoi for 50 years, and produced many notable Soviet planes such as the Sukhoi Su-7, Su-17, and Su-24. His planes set two altitude world records and two world speed records. Sukhoi was honored in the Soviet Union as a Hero of Socialist Labor and awarded the Order of Lenin three times.
