Affectionately known as 'The Black Duke', Monmouth is the only ship in service with the Royal Navy that has its name painted in black and flies a plain black flag in addition to the ensign. This is due to the dissolution of the title and the blacking out of the Coat of Arms of the Duke of Monmouth in 1685 following the Monmouth Rebellion against James II of England. Right Screen
The current MONNMOUTH was laid down in 1991 by Yarrow Shipbuilding Limited and she was launched on the 23 November 1991 by the Ships sponsor - Lady Eaton. A ceremony held at her base port of Devonport and she was commissioned into Naval service.
We shall now look at the propulsion plant of MONMOUTH to give you an understanding of how the Ship propels itself through the water.
All this talk of diesels, gas turbine and electric motors may seem a bit confusing so I will spend just a moment now to clarify how it all fits together. As can be seen from the title of the slide the Ships propulsion plant is configured by what is know as CODLAG drive, this stands for Combined Diesel Electric And Gas SO very simply we have the diesels creating electricity that powers two electric motors and when we want to go faster we start a gas turbine and clutch it onto the shaft. The two shafts are totally independent so we can have EM drive on one shaft and a gas turbine on another, this configuration is known as sided boost.
For cruising and normal operations we have four Paxman Valenta diesel generators that are used to provide electricity to two electric motors. Unlike the gas turbines the diesels are very fuel efficient, and this gives the Ship an endurance of 7800 miles at 15 knots. As I mentioned earlier the four diesel generators do not drive the shafts rather they are used to provide power to the two electric motors which power each shaft, this engine configuration is known as EM drive. This combination of Gas turbines and Electric motors gives MONMOUTH a very flexible propulsion plant. The four diesels are housed in two engines spaces, with each engine space having two diesels each. There are two diesels in the forward Auxiliary Machinery room and the remaining two are in the Upper auxiliary machinery room. Unlike the gas turbines the diesels are not housed in airtight modules. Rather the two in the Forward axially machinery room are housed in noise reducing modules whilst the two in the UAMR are as can be seen from the slide not housed in any modules. Instead, the noise that they make whilst running is reduced by the fact that they are located on the upperdeck above the waterline and this prevents their noise transmuting through the hull an into the water. This configuration is the key which makes A Type 23 such a formidable ASW weapon.
For high speed running we have two Rolls Royce SM MK1A Spey gas turbine, each turbine producees 12.75 Megawatts of power and uses approximatley 5 tonnes of fuel per hour. This is an enormous fuel consumption rate and so the gas turbines are primarily for short term use, if for instance we have to sprint in a tactical situation. For normal cruising we will try to avoid using them. As can be seen from the slide the Gas turbines are housed in their own airtight modules. This helps to reduce the noise of the turbines and should a turbine catch fire it also prevents the fire from spreading through the whole machinery space.
The weapons systems are spread evenly over the length of the Ship. The 4.5 inch gun is the forward most weapon located just aft of the f’csl, next is the Sea Wolf missile system with the 8 harpoon missiles between this and the bridge. There are five close range gun positions on either side, starting with “2x GPMG mounts forward, min guns on the bridge wings, 30mm cannons mid-ships, and finally GPMG mounts aft. The hanger located aft is split into tow zones, the forward is air weapons magazine which houses the MTLS and the after part is used to store the one of the ship’s principle weapon system, the MERLIN Marine Patrol Helicopter, and this is what we shall look at next.
We shall now move on to look at how the Ship fights and defends itself by examining the weapon fit.
The 4.5” MK8 Mod1 gun was introduced into Naval service 2003. The Mod one is an enhanced version of the standard 4.5 gun and represents a quantum step forward in gunfire capability. The main difference between the standard MK8 and the Mod is the replacement of the hydraulic control system by a totally electric one and a change in the shape of the gun housing from a rounded shape to the more angular one of the Mod 1. These changes give the Mod 1 an increased reliability and accuracy over three old gun, this in turn reduces the maintenance needed to keep the gun operational. Because of its new Shape the mod also has a reduced Radar cross section. The Mod 1 gun is a fully automatic gun that is capable of firing up to 28 shells a minute out to a range of 27000 yards. The gun can fire HE or star shell. The gun can be used to provide NGFS to troops ashore it can also be used against surface shipping and air targets.
For long range anti-ship engagements MONTROSE is fitted with 8 harpoon missiles. Harpoon is an American missile system, built by Boeing, that the RN has acquired. The missiles can be targeted in numerous ways but are autonomous once they leave the Ship. Harpoon can be fired independently, in salvos and even can be combined with the Merlins torpoedoes to arrive simultaneously at a target. Targeting information can be provided by a 3rd party, such as a Maritime Patrol Aircraft. Each missile has a range of 75 miles, and uses an inertial navigator system combined with an active Radar Seeker head to find it’s target, via a number of set waypoints. This gives us the capability to launch a number of missiles in a multi-axis attack. The missile has two attack profiles, it can be fired in either the se skimming mode or the pop up mode, where by it will skim the sea surface until the last minute before climbing and then diving steeply onto the target. Its long range, the ability to be fired in salvos with multiple attack profiles makes the harpoon missile a truly formidable offensive weapon.
To defend itself from attack by hostile aircraft and missiles the Ship is fitted with a point defence missile system comprising of 32 Vertical launch Sea-wolf missiles. The system was first proved in combat when early versions were used in the 1982 Falklands war. Sea-wolf is a radar guided missile which works in conjunction with the 911 trackers, it flies down a beam from the Ship to the target. Each missile has a range of six km. The system can be used for both AAW and ASMD, and a sutiable role for a Type 23 is that of “goalkeeper” on a mission essential unit. This means we will sit very close to a unit such as an aircraft carrier, and use our Sea Wolf system to defend the unit. Missiles can be fired either singularly or in a salvo of two, The Ship can fire four missiles a time. The old SW system on Type 22’s used a launcher based system; the silo launch system on a 23 offers a step up in capability.
Not all threats are from above the water, to counter the sub surface threat the Ship is fitted with four torpedo tubes. There are two tubes on each side of the Ship and these are housed in the forward part of the hanger. The torpedo launching system is known as MTLS which stands for, Magazine, Torpedo, Launching, System. The Ship is armed with the Stingray torpedo, which is the same torpedo carried by the Lynx. The stingray is a lightweight torpedo which travels at a fast speed which will catch any submarine, and has a range of 6000 yards. Submarines will struggle to detect a type 23 at low speeds and as such this system offers an excellent short range “surprise” weapon.
A new and developing area of warfare is that of the Assymetric threat. Traditional naval warfare is that of missiles, long range guns, submarines and large expensive surface units. In many parts of the world now we are finding our cold war designed vessels up against small fast inexpensive attack craft who may be armed with guns and rockets. Our standard weaponry is not suitable, and so we have developed new procedures to combat the threat. Short range gunnery and force protection is now one of our major forms of warfare and is becoming more important year after year. Our GPMG’s, Miniguns and 30mm offer a graduated response to any threat as well as providing an immense visual deterrent. Needless to say they offer a significant amount of firepower to stop a fast moving threat; the minigun alone will fire 3000 7.62 rounds a minute. Normally away from the UK we will have the gun crew closed up when entering or leaving harbour, or when transiting any Straits, essentially anywhere where we may be vunerable.
I would now like to move the direction of the presentation back closer to home and talk about what is our greatest asset onboard, the Ship’s company.
May I introduce you to our Commanding Officer, Commander Tony Watt. It is the task of the CO to lead and direct us all in order to ensure that this Ship and its crew is the best possible fighting unit. Commander Watt joined the Royal Navy 1987, after completing training he served as an OOW, before qualifying as a mine clearance diver. After a few years in the diving world and a stint at BRNC he became a PWO and took part in a worldwide deployment on SUTHERLAND, before participating in Op Telic as part of the Amphibious task group staff. In 2003 he was CO of HMS RAMSEY. He was appointed as CO of HMS MONTROSE in August of 2005.
Sirs, We have now come to the end of our basic introduction to Type 23 frigates, HMS MONTROSE and our current operations. We have seen how HMS MONTROSE fits into the overall RN structure, and how new units are providing the service with a step up in capability, suited to the post cold war world. You have seen how the Type 23 has evolved from its sole anti submarine roots into a true multi purpose warship. The key here is flexibility, MONTROSE can and will fulfil the primary roles of ASW, ASUW, AAW, as well as littoral patrol, NGS, disaster relief, presence operations, a boarding platform and reconnaissance. The array of weaponry and the Lynx mk8 are key, as are the ship’s company without whose flexibility and skill the ship would not succeed. We have also taken a snapshot of our current operations, and hopefully have demonstrated the variety of operations RN ships conduct in the region. MONTROSE remains a very capable unit, and will do for years to come. As roles and equipment evolve, our ship will evolve to meet these challenges. Thank you for listening, now are there any questions..
