The Antrim-class multirole frigates are a class of warship in service in the Irish Navy from the mid-1990s onwards. They were designed and built using principles of stealthy design, including the extensive use of "X-form" structure design in which right angles and vertical surfaces are avoided, and techniques to reduce the infrared signature, such as expelling pre-cooled exhaust gasses just above the waterline. Eleven of them are currently in service in the Irish Navy.
