The following is a basic guide to the actual known ship classes that have appeared on Star Trek over the last 30+ years. There are 49 so far, in addition, other hypothetical classes have been inserted to give a balanced impression of how the fleet may look and operate, going back a period of two centuries to the very beginnings of the Federation and Starfleet.

Designation refers to the class' hardware type, eg, Cruiser, Destroyer, Surveyor etc. I submit that these old marine terms are used by the Federation, for they have had passing mentions. For instance, in the Dominion war Sisko referred to the Federation task forces in categories such as 'Cruiser Wings' and 'Destroyer Units'. Detailed info on Designation specifications are found on the Definitions page.

The Dates column refers to the speculated dates when the prototype vessel of that class was first actively commissioned, and the very last ship of that class decommissioned/destroyed, etc.. 

Length and Ships Built is a conjectured figure. If the amounts of ships figure is in brackets, it indicates that further vessels in that class are planned, and the current number is only provisional, this obviously is only pertinent to 24th century classes still under construction.

Power is an approximate calculation of shield strength times offensive capability, ie, for Constitution Class the final value of 7.8 is reached.

Its (conjectured) Shield strength is 1.3, times Phaser arrays (4) and Photon launchers (2), or 1.3 x 6, totalling 7.8 -

Shield Strengths can be found listed on that class' particular page. For more info, see Definitions.

This basically gives an overall idea of how offensively powerful that particular class vessel is. For older ships (Daedalus Class) who possess the older style Laser Cannon and Fusion Missiles, a 50% power reduction calculation is considered. For middle aged classes of ship which have since been refitted, their original prototype values are noted. Quantum Torpedo and Phaser Cannon values are speculated as being twice that of Photon torpedoes, older ships since upgraded to Quantums aren't considered, only new original prototypes fitted with them are acknowledged. Phaser types are passingly acknowledged, for Excelsior Class phasers are obviously going to be considerably less powerful than Sovereign for instance (Phaser Types are detailed Here).  Final power values given are a fair indication of that class' actual armour and hitpoints capability, and a ship whose power is 100, is there or thereabouts ten times as powerful as a ship that is rated at 10. The inserted Shield Strengths (listed for each class on its page) is considered to be increased and improved as time moves on and technology advances, and the system works on an exponential curve basis like the warp scale, meaning that a ship with a shield strength of 6, is not necessarily twice as strong as a ship with a shield value of 3.

Most of this data is speculative, and not to be taken as gospel. Only for those class ships that have been visually portrayed, and whose nature, designation, size and age etc. are reasonably established, are close. All class stat details can be found in the Fleet Guides...

Please take note, some may find it strange that in the 24th century classes section certain ship classes that are believed to be new are placed in an earlier time-frame, classes like Akira and Steamrunner for instance which are listed here to be from the 2360's. Construction dates are based on the given registries for ships we know, and these two classes seem to be contemporary to at least Galaxy Class, or perhaps even (incredulously) pre-date it. But, with a lack of actual canon dates for class constructions one has to make do with scant available fact, and speculation to fill in the (many) loopholes.

*The San Antonio Class saw the breakthrough in weapons technology -the introduction of Photon Torpedoes in 2216, the implementation of these devices greatly increased a vessel's offensive power. All other stars ( * ) refer to similar breakthroughs in weapons technology and efficiency that boost overall offensive power values.

*The Soyuz prototype saw the introduction of new shield grids, or 'deflector screens' as was the fashionable term at the time. These strengthened screens were also used during the Constitution Class upgrades during the early 2270's.
