Description

Introduction

The Antonov An-22 is a strategic airlifter of Soviet origin. It was developed to supplement the An-12 with the ability to transport larger and heavier loads over much longer distances. When introduced the An-22 was one of the world's first widebody transport aircraft. It remains the largest turboprop-powered aircraft to date.

Design

The An-22 is a very large transport aircraft with high mounted wings. It is powered by four turboprop engines with counter-rotating propeller blades. The large wheels and sturdy undercarriage allows the An-22 to use unpaved landing strips. A large rear ramp allows for large payloads. These include vehicles and helicopters, such as the Mil Mi-8, to be transported. As such it has the ability to drop airborne troops including four of their parachute-equipped BMD-1 combat vehicles.

Variants

An-22 (prototype)
3 prototypes were produced by Antonov. These aircraft featured a large glass nose and lack the radar found in production aircraft.
An-22
Main production model produced by TAPO. A total of 37 aircraft produced.
An-22A
Improved production model produced by TAPO. A total of 28 produced. Fitted with updated navigation, communications and electrical systems.

Users

The USSR was the only user of the An-22. A small number was/is used by civilian airlines. The Soviet aircraft were transferred to Russian when the Soviet Union fell. Only a very small number remains in service today. About 3 aircraft are known to be operational as of 2020.
