Welcome everyone, Green here bringing you my second forum of the series on the UK Royal Navy. Today we are going to have an in-depth look at the UK class 23 frigates. The Type 23 class is the largest class of frigate constructed for the Royal Navy since the 26 ships of the leander class. Like the leanders they type 23 provides the back bone of the Royal Navy's anti sub frigate force, and with any luck should continue to do so for many more years. The ships where designed to complete that role in the rough waters of the North Atlantic using their towed array sonar. The Type 23 where the first stealthy ships to enter service in the Royal Navy with hull angled off the vertical to reduce a radar signature. After the Falklands war Harpoon anti-ship missiles and a 144 mm gun where added to give the design a better punch. The ships will also receive the new powerful towed sonar 2031Z which equips the ten of the class. This sonar will allow the ships to find much quieter modern submarines that may operate in inshore waters in the future. Further studies are in hand to find ways to extend the lives of these large and capable vessels and further enhancing their military capabilities.
