WASHINGTON, Dec. 3 (UPI) -- The U.K. Royal Navy's upgraded Merlin Mk2 anti-submarine warfare patrol helicopter will deploy for anti-piracy and anti-terrorism operations in the winter.
The helicopter entered service in the Royal Navy in 2014, later declared fully operational in the summer of 2015 after a series of tests and trials in European waters. The trials included large-scale anti-submarine exercises in the Atlantic Ocean. The Mk2 version replaces the Royal Navy's earlier Mk1, with improvements including a fully integrated electro-optic and infrared camera.
