The ship was initially armed with a single Bofors 40 mm L/60 gun, although by 1990 this had been replaced by an Oerlikon 30 mm gun on a DS30B mount. The main armament was supplemented by two 7.62 mm machine guns. A large helicopter deck was fitted aft, suitable for landing a Sea King or Chinook helicopter, but no hangar was provided, as the cost of a permanently embarked helicopter would be more than the cost of the ship. She was fitted with Type 1006 navigation radar, which was supplemented with a Type 994 air/surface search radar in 1986, together with a UAN(1) electronic intercept system (based on the Orange Crop system fitted to the Royal Navy's helicopters.
