Federation-Class Refit Dreadnought 1:7000

This model is scaled in 1:7000 for fleet scale miniatures games

The Federation-class were a type of class I (mk X) Federation starship, the first ever Starfleet dreadnoughts, authorized for construction on stardate 6066 in the 23rd century as a variant using components similar to those of the Constitution-class

The "space battleship" of the Starfleet, the Federation-class were the largest and most powerful ships until the advent of the refitted Enterprise-subclass Constitution refits, in 2272. As it turned out, the Federation was slightly inferior to the dreadnoughts of other powers.

The original design concept of the dreadnought was to include more capabilities but only a minimal increase in firepower over Constitutions. This was found to be inadequate after other powers began fielding dreadnoughts that reflected a 50% increase in firepower over their respective heavy cruisers.

Each late-23rd century Starfleet fleet and Starfleet task force was usually commanded by an admiral in a dreadnought, but during peacetime the dreadnought is usually docked at a starbase because it is too expensive to operate. 

One of the reasons that the Federation design was not as efficient was the three-warp nacelle configuration, which was found to be much less workable than a vessel with an even number of warp engine units. 

By the 2280s, the Federation-class vessels had been modified into a refit version based on similar changes made to Constitution-class vessels.
