Brave-class patrol boat

The Brave-class fast patrol boats were a class of two gas turbine motor torpedo boats (MTBs) that were the last of their type for the Royal Navy (RN) Coastal Forces division. They formed the basis for a series of simpler boats, which were widely built for export.

At the time of their introduction the Braves were the fastest naval vessels in the world.

Brave class
The Brave class followed the of convertible motor torpedo boats/gunboats. They were larger than the Dark class, and differed in being powered by gas turbine engines rather than the diesel engines of the Dark class. (Gas turbine propulsion had been tested in the of two experimental fast patrol boats). Three Bristol Proteus engines propelled the Braves to a maximum of 52 kn. Like the Dark class, the Braves had a mahogany skin over aluminium frame construction. They were built to be able to be used as either motor torpedo boats or motor gun boats. For the former role they had a 40 mm Bofors gun, four 21 in torpedoes and two depth charges, in the latter two 40 mm guns and two torpedoes. It was planned to arm the ships with a new 3.3 inch gun based on the 20-pounder tank gun in a stabilised mounting, but this was abandoned.

The Royal Navy abandoned the idea of large scale coastal forces in 1957, so only two Braves were built for the Royal Navy. The two Braves, along with a single member of the Dark class, formed the Coastal Forces Trials and Special Service Squadron, based as Gosport. These were used to maintain proficiency in Coastal Forces operations, also being used as targets and for fishery protection. The two Braves were retired from use in 1970.

Ferocity and derivatives
The Braves were expensive boats, so as a private venture, Vospers produced a simpler derivative, Ferocity. This was smaller than the Braves, with an overall length of 90 ft and was powered by two Proteus engines instead of three, which were supplemented by two diesel engines for cruising. Construction was all wooden to minimise costs. Despite the reduced size and power, performance and armament were similar to the Braves. While Ferocity herself was not sold, it formed the basis for a number of boats for export. These included sales to West Germany (two, called the Vosper class), Denmark (five of the Søløven class), Greece, Malaysia for the RMN in 1966 (four craft), Brunei and Libya, and was also the basis for the.

Boats
The two RN craft were both built by Vospers at Portchester:
 * HMS Brave Borderer (P1011), launched on 7 January 1958 and commissioned on 26 January 1960.
 * HMS Brave Swordsman (P1012), launched 22 May 1958 and commissioned on 20 July 1960.

At the end of their life they were sold to the Haydon-Baillie aircraft museum.

Denmark
Denmark purchased six Søløven-class fast patrol boats, with the larger hull form and the 3-Proteus powerplant of the Brave class and the wooden construction of Ferocity. Armament consisted of two 40 mm Bofors guns and four torpedoes. The first two boats, Søløven and Søridderen were built by Vospers (with Søløven being paid for by the United States and hence given the nominal US designation PT-821), with the remaining four boats being built under license by the Royal Dockyard, Copenhagen. They were placed into reserve in 1988, and disposed of when the s entered service, all being disposed of by 1992.

One of the Søløven-class boats, looking to be in a derelict state, was being auctioned in Belgium from 12–24 February 2016, being moored alongside another in Antwerp harbour.

West Germany
West Germany ordered two fast patrol boats (both designated Type 153) from Vospers on 22 August 1960. The first, Strahl was based on the Brave class, with three Proteus gas turbines, while Pfeil was based on the smaller Ferocity with two Proteus. Armament was the same convertible combination of Bofors 40 mm guns and torpedoes as the Brave class, with the option of replacing the torpedoes with eight mines. They were transferred to Greece in 1967.

Libya
In October 1966, Libya ordered three fast patrol boats of the Susa class from Vospers based on the Danish Søløven class, with the wooden construction of Ferocity but a larger hull powered by three Proteus engines. Armament of eight SS.12 wire-guided anti-ship missiles and two 40 mm Bofors guns.

Malaysia
The Royal Malaysian Navy ordered four Perkasa-class fast patrol craft on 22 October 1964 to be designed and built by Vospers. The design was similar to the Danish Søløven class, with a large (30.4 m) wooden hull with an aluminium superstructure and powered by three Proteus engines. The original armament was four torpedoes (which could be swapped for 10 mines), a single 40 mm Bofors gun forward and a twin 20 mm Oerlikon cannon mount aft. The four boats were delivered in 1967 and re-armed with eight SS-12 missiles in 1971.
 * KD Perkasa P150
 * KD Handalan P151
 * KD Gempita P152
 * KD Pendekar P153

Brunei
A single boat of the class was purchased by the Royal Brunei Navy, KDB Pahlawan.

Model
In the 1970s the Japanese model company Tamiya produced a 1:72 scale model of KD Perkasa.
