This is the Tri-ang Minic Ships set of Royal Navy submarines containing models of a Vanguard Class Nuclear Ballistic Missile Submarine (SSBN) and a Trafalgar Class Nuclear Attack Submarine (SSN).

Vanguard Class SSBN -

The Vanguard Class Submarines were designed to deploy the Trident Missile system replacing the aging Resolution Class which deployed the Polaris Missile system, Britain's initial nuclear deterrent.

The boats were based largely on the American Ohio Class the major difference being that the Vanguard Class was designed with 16 missile tubes instead of the 24 missile tubes of the Ohio Class boats.

Twice as heavy and twenty metres longer the new Vanguard Class Submarines had many advantages over the Resolution Class including more space, with a fourth deck, and less crew due to increased automation. They also have improved sonar and carry the Spearfish torpedo.

The development of the Trident Missile system received much interest from Russian intelligence and in what was dubbed "The Hunt for Red December" Russian submarines trying to monitor Vanguard's sea trials in December 1993 were chased across the Norwegian Sea by British frigates and submarines.

Upon embarking on her first operational patrol Vanguard was the subject of further Russian interest and it is rumoured that at least two Trafalgar Class submarines, one of which was HMS Torbay, escorted her as she left the Clyde approaches and headed into the open ocean.

In 1993 it was announced that Devonport had won the contract to refit and refuel the four Vanguard Class Submarines at a cost of $5 billion. Since the announcement a large amount of money has been spent constructing the facilities needed for the refit including the conversion of a 90 year old battleship drydock into a modern earthquake proof refit complex.

The four Vanguard Class Submarines are members of the 1st Submarine Squadron based at HM Naval Base Clyde (Faslane). There has been an investment

The Vanguard Class can carry sixteen Trident II (D5) Missiles which have a range of 4,000 nautical miles (around 11,000km). Each missile is 13 metres long, weighs 60 tonnes and can carry up to twelve warheads each of which can be programmed to attack different targets. 

At any single time there is at least one Vanguard Class Submarine on deterrent patrol its location and course a closely guarded secret known only by the most senior officers onboard and ashore. Once they leave Faslane they submerge and do not resurface until they return. 

The model is marked on the underside with the Tri-ang Minic logo, the model number P 770, "Royal Navy Modern Edition", and the description "Vanguard Class Submarine".

Trafalgar Class SSN -

Originally designed for Cold War operations in the Mediterranean and North Atlantic the Trafalgar Class design was a follow on from the successful Swiftsure Class but incorporated many improvements making them both faster and quieter.

The hull of is covered by anechoic tiles to absorb sonar signals and noise reduction is achieved through the pump jet propulsion system which is a multi blade rotor turned by a jet of water that is quieter than a conventional propeller. The lead ship HMS Trafalgar was completed in 1983 before the pump jet propulsion system was ready and has a seven bladed propeller instead.

Like previous British nuclear submarines the Trafalgar Class boats have a "teardrop hull", the fin has been strengthened and the hydroplanes can be retracted to allow the submarine to surface through ice.

The principle role of these "hunter-killer" vessels is to attack ships and other submarines and in this capacity they could support and protect a convoy or taskforce. With the fitting of the Tomahawk cruise missile system they will also be capable of a land attack role.

The Trafalgar Class are fitted with cameras and thermal imaging systems that allow them to be used in a surveillance role. 

The model is marked on the underside with the Tri-ang Minic logo, the model number P 790, "Royal Navy Modern Edition", and the description "Trafalgar Class Submarine".
