The Steamrunner class was a type of Federation starship in service with Starfleet during the late 24th century. Utopia Planitia Fleet Yards was one of the sites this class was constructed at in 2371.

Entering service some time during the early-2370s, the Steamrunner-class was a common fixture in Federation fleet deployments, appearing on the front lines of numerous engagements, including against the Borg and the Dominion.

The Steamrunner-class saw action at the Battle of Sector 001 in 2373, where several were lost.

In the years to follow, several vessels of this class were assigned to Starfleet's Second Fleet during the Dominion War, which participated in Operation Return in 2374, the second Battle of Chin'toka, and the Battle of Cardassia in 2375. They were also frequently stationed near Deep Space 9 during the war.

At least one member of the class was within a light year of Earth in 2378.

NOTES:


1 - Depleting the MDC of the Main Hull will render all systems inoperable and probably destroyed and unsalvageable.

1B - Destroying the Bridge will automatically switch control to main engineering in the engineering section. Once control is established in the battle bridge efficiency of the vessel will only be affected as follows, -5 to all combat rolls and attacks per melee are halved.

2 - Destroying the sensor dish will deprive the ship of all forms of long range communications, radar and targeting. The range and targeting capabilities of the secondary systems are equal to that of a shuttlecraft at best. The ship can still operate, but is at -3 on initiative, -3 to strike, and number of attacks per melee of the weapon systems are reduced by half.

3 - Destroying the main hanger will not be able to deploy any craft until it is repaired. Under normal operations the carrier can launch or recover up to 3 shuttles per melee.

4 - Depleting the MDC of the the warp nacelles will force the ship to rely on its Impulse engines. Depleting the MDC of the main engines AND secondary engines will leave the ship adrift in space with very minimal movement allowed by its docking thrusters. If in an atmosphere, the ship will crash.

5 - Shields regenerate at 75 mdc per melee. Only if a generator is damaged will the ability for shields to regenerate be hampered
