Armstrong class

The Armstrong class was a class of starship in service to Starfleet in the mid to late 23rd century.

Physical Arrangement
The Armstrong-class was composed of a single primary hull, consisting of a saucer that was similar to that of the Constitution-class; however, the bridge module, positioned on top in the center, was shaped differently than the Constitution-class module.

Ships of this class had the unusual distinction of having three warp nacelles, two outboard and one inboard. These nacelles were connected by swept pylons to the underside of the primary hull. Similar to the future Miranda class starships, which drew its design from both the Armstrong and Soyuz classes, a Armstrong-type starship was equipped with a rollbar supporting a multi-tube torpedo launcher. Extending from the trailing edge of the primary hull, and connected to the rollbar by smaller pylons, there was a structure housing the impulse drive.
