The O17 (Nahuatl: Octacatl 17, development designation Tepoztetl-121) is a Zacapine main battle tank based on the experimental platform Tepoztetl-100 designed in the 1980s, and the Tepoztetl-41 from the 1950s. It was formally adopted by the Zacapine military in 2017, with a test batch of 15 units already in service while delivery for the main production run of 65 O17s is expected to begin in 2025. The O17 is considered to be a next generation armored vehicle and represents the most sophisticated piece of equipment in service with the Zacapine ground forces, rivalling many naval and aerial projects in other branches of service. As a result of the extensive technical and financial requirements of the project, the development of "Tepoztetl-121" has been ongoing for 25 years and has become the central project of the Zacapine army's development wing for the better part of a decade.
