In July 2017, Bell Helicopter and Polish Armaments Group signed a letter of intent planning on cooperating on the UH-1Y and AH-1Z helicopters, forming a potential bid for the Polish Kruk attack helicopter acquisition program, part of a wider modernization effort. In October 2017, Thailand's minister of Defence Prawit Wongsuwan stated that Thailand is looking onto replacing its fleet of aging AH-1F Cobra attack helicopters and will launch a procurement committee to look into the matter. Royal Thai Army officials have said that the Army is looking into the Bell AH-1Z Viper, as well as the Agusta A129 Mangusta, Mil Mi-28, CAIC Z-10, Bell AH-1 SuperCobra and Boeing AH-64 Apache.
