The UK Royal Navy's Type 23 Duke-class ship HMS Iron Duke has completed an engineering assessment in the South Coast exercise area.
The weeklong evaluation of the frigate was managed by staff from Maritime Commissioning, Trials, and Assessment (MCTA), as part of its regeneration programme.
During a series of dynamic trials, the performance of the vessel's propulsion, power generation, and auxiliary machinery, as well as other on-board equipment were evaluated.
Engineers also tested the sensors, weapons, and communication systems.
Engineering Technician Adam Hilton said: "It was really satisfying to test and push the equipment that we maintain, even better to know at the end of it that the hard work conducted during our regular maintenance ensured the ship remains on top form."
The tests are designed to ensure reliability and operational capability of the Iron Duke, Royal Navy said.
The 133m-long Duke-class vessels feature vertical-launched Seawolf point-missile defence system and the Boeing Harpoon surface-to-surface missile for anti-submarine warfare and anti-surface warfare capabilities.
The 4,900t vessels can accommodate approximately 180 crew members, and are powered by a diesel-electric and gas (CODLAG) system comprising two Rolls-Royce Spey SM1A 34,000hp gas turbines and two Alstom 1.5MW 4,400hp electric motors.
