The Armstrong class was a class of cruiser fielded by the Federation Starfleet during the 22nd and 23rd centuries.

The Armstrong class entered service in 2197 and along with the Venture-class was meant to replace the aging Daedalus-class explorer. The Armstrong shared several design features with the Daedalus. The ship was made up of a spherical primary hull, which was more ovoid than that of the Daedalus, connected directly to a cylindrical engineering hull.

The Armstrong is also said to be one of the first classes to have ship-based transporters as part of its initial design due to the technology becoming available in 2186. Star Trek: Enterprise would later set in canon that ship-based transporter technology had existed since the early-2150s.
