History and specifications

Authorized by the Perimeter Defense Directive in the 2360s, the Steamrunner-class vessels were designed for patrolling the Federation borders, responding to border incursions, and for intelligence gathering.

Steamrunner-class vessels crewed 200 officers and cremwembers, with room for up to 50 passengers or an additional 550 evacuees. The vessels measured 375 meters in length and had 18 decks. The Steamrunners had four standard personnel transporters, four emergency transporter stages and four cargo transporters.

The Steamrunner warp engines were rated to cruise at warp factor 6, with a maximum speed of warp 9.2 and maximum drive of warp 9.7. The Steamrunner impulse engines were capable of between .75 to .95 the speed of light at upper limit. The Steamrunner weapons had a full 720-degree firing arc of type X phaser emitters, and two torpedo launchers with forward, and aft firing arcs and a normal loadout of 250 photon torpedoes. Steamrunner ships were defended deflector shields and ablative armoring. (TNG roleplay module: The Price of Freedom; ST roleplay module: Starfleet Operations Manual)

Background

Apocrypha

The RPG The Dominion War Sourcebook: The Fires of Armageddon, published by Last Unicorn Games after they had lost their Star Trek licence listed additional Steamrunner-class starships: The USS Cutasi (NCC-73815), USS Nath'qu (NCC-71115), USS Orobouros (NCC-72405) and USS Persepolis (NCC-70364). The apocryphal Ship Recognition Manual, also from LUG, list several registry numbers of Steamrunner vessels.

The Steamrunner-class was a type of Federation starship in service with Starfleet during late 24th century.

The Steamrunner-class is one of the more unusual designs fielded by Starfleet. The ship has does not follow the usual separate saucer and engineering hulls with both sections combined into a single frame. The warp nacelles are connected directly to the hull and extend out the back of the vessel. This gives the ship a very streamlined appearance. At the rear of the nacelles connected by pylons is a housing with the main deflector suspended lower than the rest of the vessel such that from the front the deflector is clearly visible.

The vessel is also equipped with phaser arrays and torpedo launchers to defend itself and Federation interests. The early to mid-2370s saw the class put these features to much use in engagements with the Borg to the Dominion War.

The ship is equipped with numerous escape pods.

Like the Akira-class the Steamrunner is built with a through-deck shuttlebay allowing it to accommodate a large number of auxiliary craft, including up to thirty Peregrine-class attack fighters. (LUG RPG: Ship Recognition Manual, Volume 1: The Ships of Starfleet)

Naming schema

At least one block of Steamrunners were named after mountains or mountain ranges of planets in the Sol system. (Ships of the Star Fleet, Vol. 2: Patrol Combatants. )
