H.M.S. "Brave Borderer", first of the Royal Navy's all-turbine "Brave" Class Fast Patrol Boats, went?
H.M.S. "Brave Borderer", first of the Royal Navy's all-turbine "Brave" Class Fast Patrol Boats, went through demonstration trials at Portsmouth, U.K., September 18.
Believed to be the fastest warships in the world to-day with a speed in excess of 50 knots, the Brave Class Patrol Boats - 96 feet long and 23 feet 11 inches beam - are powered by three Bristol Proteus marine gas turbines, each of 3,500 HP.
The Bristol Siddeley Marine Proteus engine is the marine version of the Proteus turboprop fitted to the Britannia airliner.
Built by Vosper Limited of Portsmouth, these speedy craft, constructed of welded aluminum alloy, planked in mahogany and sheathed in fibre glass below the water line, have such great manoeuvrability that the helm can be put hard over at full speed.
With accommodation for 3 Officers, 3 Petty Officers and 16 Ratings, and with either Gunboat armament of two 40mm Befors guns or Torpedo-Gunboat armament of one 40mm Before and four 21-Inch torpedoes, these craft are designed for offensive operations in enemy coastal waters, or for a defensive role protecting British coastal waters.
