Powerful and versatile with the capability to operate anywhere in the world, the type 23 frigate is the mainstay of the modern surface fleet. The 14 Type 23 frigates form 50% of the total frigate/destroyer force in the Royal Navy. Originally designed for the principal task of anti-submarine warfare, they have evolved into powerful and versatile multi purpose ships with the capability to operate anywhere in the world. The effectiveness of these ships is enhanced by their stealth design, which reduces their radar signature significantly. In addition to the war fighting roles described above, the ship is trained to conduct a wide range of other tasks. These include embargo operations using boarding teams inserted from the ship's boats or helicopter, disaster relief work and surveillance operations.
