The Ironclad gas field is a natural gas field located offshore the Cabo Delgado Province of Mozambique. Discovered in 2012, it was developed by Anadarko Petroleum, determining it to have initial total proven reserves of around 5 trillion ft3 (143 km3). It began production of natural gas and condensates later that year, with a production rate of around 50 million ft3/day (1.9×105 m3).
