The VCA-155 (Vehículo de combate de Artillería, Artillery Combat Vehicle) is a self-propelled 155 mm gun/howitzer, manufactured by TAMSE (Tanque Argentino Mediano Sociedad del Estado) which entered service in the late 1990s.

[1] It uses a TAP chassis (Tanque Argentino Pesado, Argentine Heavy Tank), an abandoned project derived from the TAM (Tanque Argentino Mediano, Argentine Medium Tank).

It has a 155-mm howitzer "Palmaria" turret of Italian origin.

[citation needed] In conjunction with the VCCDT (Vehiculo de Combate Centro de Direccion de Tiro - Combat Vehicle, Fire Control Centre) it makes up a modern system of artillery weapons.

It also operates an integrated system for artillery fire campaign called "TRUENO", which enables it to direct artillery fire in an automated mode.
