Registry:	NCC-1715
Affiliation:	Federation, Starfleet
Launched:	reference stardate 2/0008

The USS Challenger (NCC-1715) was a Federation Constitution-class (of the Mk II Bonhomme Richard-subclass) class I/class IX heavy cruiser starship in service to Starfleet in the 23rd century.

The Challenger was built to Mk II specifications and entered service on reference stardate 2/0008. She was later refit to Mk III (Achernar-subclass) specifications on stardate 2/0508. The Challenger was later refit to become a Mk I Enterprise-subclass on stardate 2/1707. (FASA RPG module: Federation Ship Recognition Manual)

The Challenger was due to be recommissioned about a month after stardate 8036, in the 2270s. Commander Patrick Brady was assigned as the vessel's first officer, and took a short assignment as acting first officer of the USS Enterprise for training. (TOS novel: Enemy Unseen)

In 2275, the Challenger was docked at Starbase 18. She was a candidate to test the new inversion drive technology, but lost out to the USS Enterprise. (TOS novel: The Wounded Sky)
