U pitanju je varijanta P ( Patrolni ) ,ima o tome u prvom postu .
Ono po cemu je karakteristican An-72 jeste u praksi iskoristen poznati `Koandin efekat` .
Citat:Avro's 1956 Project 1794 for the US military designed a larger-scale flying saucer based on the Coandă effect and intended to reach speeds between Mach 3 and Mach 4.[8] Project documents remained classified until 2012.
The effect was also implemented during the U.S. Air Force's AMST project. Several aircraft, notably the Boeing YC-14 (the first modern type to exploit the effect), NASA's Quiet Short-Haul Research Aircraft, and NAL's Asuka research aircraft have been built to take advantage of this effect, by mounting turbofans on the top of wing to provide high-speed air even at low flying speeds, but to date only one aircraft has gone into production using this system to a major degree, the Antonov An-72 'Coaler'.
