The US Navy and the US Air Force selected the Beech Pilatus PC-9 Mark II, now named the T-6A Texan II, as the Joint Primary Aircraft Training System (JPATS). The T-6A Texan II, manufactured by Raytheon Aircraft in Wichita (a subsidiary of Raytheon Company), is a primary trainer that will also accommodate instruction in advanced aerial and air-to-ground manoeuvres. The aircraft is capable of providing over 155 hours of training including weapons delivery training.
