The Tronador I (T1) vehicle was flown successfully on June 6, 2007[3][4] from Puerto Belgrano Naval Base near Bahía Blanca,[3][5] in the south east of the Buenos Aires Province.

This was the first cooperative test flight between Comisión Nacional de Actividades Espaciales and Brazilian Space Agency; it was successfully flown in December 2007 (Operacion Angicos).

[6][7][8][9] The payload built by CONAE, carried several experiments to validate subsystems for the program such as: IMU (Inertial Measurements Unit, that used IFOG's), GPS receptor (for navigation), all integrated into the on-board computer, and an attitude control system via cold-gas thrusters.

The payload unit completed a suborbital flight carried by an AEB-built VS-30 solid-propellant rocket booster, and was then recovered from the sea after landing with parachutes.

As of 2020, Tronador II's maiden orbital launch is expected to fly in "the next 4 years", according to the National Commission for Space Activities.

In early 2015, an evolved configuration[11] was presented at the 52nd Committee on Peaceful Uses of Ultra-Terrestrial Space meeting[12] and at the Punta Indio (35°31′25″S 57°11′05″W / 35.523496°S 57.1846139°W / -35.523496; -57.1846139 (Centro Espacial Punta Indio - Sector L)) test launch pad: As of June 2016, the proposed Tronador II configuration was:[13] In late 2022 Tronador II was named TII-250, with the launch site being indicated as Centro Espacial Manuel Belgrano (CEMB), in Bahía Blanca.

[18] The recent strategy was to fly separately several suborbital experimental subsystems, called "VEx", before they are incorporated in the prototype of the Tronador II rocket.

[2][17][20][21][22][23] After a few launches, it was decided in 2017 to stop the experimental VEx series as enough data was obtained to go ahead with a prototype rocket.

[30] The vehicle would have tested several technologies, new fuels, and for the first time, the interstage separation (mechanical and automatic aspects), and the ignition of the second stage.

[32][33][34][35] Test flight - single stage 30t thrust engine rocket - it was projected for a 2018 launch from Pipinas, Punta Indio Partido.
