HMS Pembroke (M107)  HMS "Pembroke" is a of the Royal Navy. She was the second ship launched of the second batch of the class, which had several improvements over the first five ships built. The ship was posted for three years to the Persian Gulf between 2009 and 2012. "Pembroke" has since been deployed in international exercises and in historic ordnance detection in home waters. "Pembroke" was the first of the Royal Navy’s Mine Countermeasures Vessels to be fitted with the Oceanographic Reconnaissance Combat Architecture combat system to replace the previous NAUTIS combat system in early 2020. The "Sandown"-class minehunter was designed to complement the existing , by providing a cheaper alternative and specific mine hunting service. The "Sandown"-class vessels were delivered in two batches, with the first five ships delivered by Vosper Thornycroft to the Royal Navy by November 1994. The company was then awarded the contract for a second batch of seven vessels, of which "Pembroke" was the second. Ships of the "Sandown"-class had a hull constructed from glass reinforced plastic, and equipment on-board have a low magnetic signature. While under normal circumstances, the ship operates on diesel engines, when operating near mines she uses an electric drive system. In addition to the bow thrusters, she is also equipped with a Voith Schneider cyclorotor. Further anti-mine equipment includes the Seafox mine disposal system. Ships of the class were each equipped with a single 30mm DS30M Mk2 gun. "Pembroke" was constructed at the Vosper Thornycroft in Southampton, England. She was used for shock trials on the improvements made to the second batch of "Sandown"-class minehunters. "Pembroke" was posted to Persian Gulf duties in 2009, and spent the following three years conducting operations and exercises there. In 2012, she returned to HMNB Clyde. On the way, she and provided assistance to "Delhi Express", a cargo vessel which had lost power while transiting the Gulf of Aden. "Pembroke" and "Middleton" protected the ship until it was under way once more, as the area is known for piracy. During the mission to the gulf, the ship had been manned by seven different crews. Upon returning to Faslane, she was placed in dry dock for two months for maintenance. "Pembroke" underwent a six-month period of support work and upgrades by Babcock International.
