Description / Specifications

The Empress Troyhune is very inexpensive for a vessel of its size; compare the Ghalalk class Heavy Crusier. Saving has resulted from several factors. First, the planetoid hull is very cheap in comparison to a manufactured hull, especially if the cost of armor protection, integral to the planetoid, is included. Second, the cost of a jump drive is immense, and its elimination presented a considerable saving. Yet despite its low cost, the monitor would almost certainly emerge the victor in a battle with the armored cruiser, even with a fifth of its tonnage unused. If the monitor were refitted with triple turrets and additional weapons or defenses were mounted in the unused space, at a not very considerable additional expense, it superiority would be even greater. Planetoid-hulled monitors thus have an obvious appeal to planetary navies unconcerned with large scale naval maneuvering.

This design also illustrates some of the advantages possessed by battleriders versus battleships, although the cost advantages are largely eliminated when the cost of the fleet tender is included. Still, a squadron of eight 50,000 ton battleriders in a million ton tender approximates in price two Tigress Class Dreadnoughts, yet possess much greater firepower and survivability.

History & Background / Dossier

The Empress Troyhune class Planetoid Monitor was originally constructed in orbit above Mora (Spinward Marches 3124) in 1067 for system defense. Budget constraints, its experimental nature, and provision for future ship expansion meant that the ship's tonnage was not fully utilized as constructed. Many turrets were installed as dual rather than triple mounts, and a sizable fraction (nearly 9,000 tons) of the ship remain unused. Originally, it was envision that this 9,000 tons of space would be later committed to additional heavy fighter squadrons and launch tubes. So far, this has not been the case, although the empty interior space has proven useful in other ways.

In 1101, the monitor was declared surplus to the need of the Mora system and was acquired by Rorise (Spinward Marches 3022) for system defense purposes. Transport to its new home presented somewhat of a problem, as neither the navies of Mora or Rorise possessed a transport ship of sufficient capacity to carry the monitor, and commercial ships of that size are unknown in the Spinward Marches. An appeal to the Imperial Navy brought eventual results, and during the fleet exercises of 1104 the million-ton Gorodish Class Fleet Tender carried the Empress Troyhune to Rorise in place of one of its Hadrian class Battle Riders
