From publisher blurb:
Designed to provide heavy support for independent cruiser squadrons, act as cruiser squadron flagships, to undertake escort duties and to engage in commerce raiding, the Lion-class battlecruisers of the Royal Navy are recognized as being the most modern capital ships in service with any national navy.
Taking advantage of TL13 innovations in Earth Sector, the 5000 tonne Lion-class battlecruiser is massive and armed to the teeth. This large ship stands ready to defend the British colonies and take the battle to those who would threaten their holdings.
The Lion-class features full deckplans by Michael Johnson with beautiful artwork by Ian Stead. The book also includes information and statistics on the British Space Systems Type 15 Voidswarm Capital Ship Torpedo and the British Space Systems Type 21 Voidlance Capital Ship Torpedo.
Climb aboard the Lion and see why some call it the "King of Space".
