Prototype

A prototype was the common designation for a first working model of a new invention, used for trial runs.
== History ==
In 2371, the Obsidian Order tested a prototype quantum stasis field, which prevented a Changeling from altering its biomolecular structure. ()
In 2373, Starfleet Science developed a prototype of a device called a polaron emitter, designed to expose Changelings by rendering them unable to maintain solid form. The untested nature and the complicated means of placement and activation made Miles O'Brien remark: "I hate prototypes". ()
Concerning starships, Starfleet prototypes had an "NX" prefix in the registry number, as opposed to the normal "NCC" prefix, and which were typically the first vessels in their class. (; ; ) Once certified for operational status, however, these prototype vessels usually reverted to a more standard NCC prefix. (; ; )
