Estadio Huachipato-CAP Acero (Compañía de Acero del Pacífico), known until 2015 as Estadio CAP,[3] is a football stadium located in Talcahuano, Chile. Inaugurated in 2009,[4] it is the home field of Huachipato, replacing Estadio Las Higueras, which was demolished in 2008. The stadium capacity is 10,500 people (all-seated).
Due to the effects of the 2010 Chile earthquake that severely damaged Estadio El Morro, Naval played their home matches in Huachipato-CAP Acero until 2012. The stadium is also rented by other teams as a neutral ground for football matches when their own grounds are unavailable.
