English: Pictured is the foc'sle of HMS Montrose in convoy with other warships in the Mediterranean Sea off Taranto, Italy. Some of the weapon systems of the Type 23 Duke class frigate can be clearly seen.

At the bottom of the image the ship's Harpoon anti ship missile launcher is shown. Upto 8 missiles can be carried by the ship, fired from a quad barrelled launcher, one on each side of the ship. Harpoon is effective to a range of approximately 92km (50nm). When launched it races towards it's target at over 500mph or 50 metres per second.

Above this can be seen the many hatch covers of the vertical launch Sea Wolf missile launcher. Sea Wolf is a surface-to-air system designed to be effective against aircraft and other missiles. The missiles are carried in 4-tube cells forming a silo on the deck. Missiles are launched vertically by a booster motor to clear the ship's super-structure and rapidly flipped onto their flight path by thrust vectoring for their journey to the target. The boost and vectoring stages then separate. Sea Wolf is powered by the Blackcap solid-fuel rocket to a maximum velocity of Mach 2 and can intercept targets in the range of 1km to 6km and 10 metres to 3000 metres in altitude.

Forward from the Sea Wolf system at the top of the picture HMS Montrose's 4.5inch Mk8 gun. The primary purpose of the gun is Naval Gunfire Support, the provision of artillery bombardment against shore targets. In this role the gun is capable of firing a 21kg shell at 25 rounds per minute in excess of 22,000m and can provide artillery support equivalent to three shore based batteries. The Mk 8 can also be used effectively against surface targets at sea as well as a limited anti-air capability.
