Soyuz class

The Soyuz class was a type of Federation starship, serving in Starfleet during the late 23rd century before its retirement by 2290. One Soyuz-class ship was the USS Bozeman, initially thought lost in 2278. (TNG: "Cause and Effect")

Exterior Design

Similar in design to the Miranda class, the typical Soyuz class starship had an enlarged aft section housing cargo- and shuttlebays. Several large outboard sensor pods, sometimes mistaken for heavy weapon mounts, also graced the enlarged aft section.

Nomenclature

The class, as well as the lead ship and prototype, were named after a series of spacecraft launched by the Soviet Union and Russia in the 20th and 21st centuries.

Alternate continuities

Pocket Books/Diane Carey's Ship of the Line

This novel designates the Bozeman and other Soyuz-class starships as "border cutters" and gives them duties similar to ships of the United States Coast Guard of earlier centuries. (TNG novel: Ship of the Line)

Fan continuities

Hobbyist's Guide to the UFP Starfleet

This continuity posits that there were only three Soyuzii built, USS Soyuz (converted from a Coventry-class hull in 2259), USS Bozeman and USS Collins (the last two converted from Miranda-class frigates in 2260).

The class ships were designated as survey frigates. Collins was destroyed in 2265. The Soyuz and Bozeman were refit in 2274. (Hobbyist's Guide to the UFP Starfleet, Part 1a)

Specs:

• Length: (original) 243.8 m; (refit) 247.1 m
• Width: 148.2 m
• Height: 73 m
• Displacement: (original, estimated) 700,000 mt; (refit, estimated) 800,000 mt
• Ship's complement (estimated): 35-45 officers; 250 non-commissioned and enlisted
• Weaponry: (original) 6 Type VII phaser emitters in 3 twin banks on primary hull; (refit) 12 Type VII phaser emitters in 6 twin banks on primary hull
• Defense: 2-layer conformal forcefields
• Cruising speed: (original) warp factor 6; (refit) warp factor 7
• Maximum speed: (original) warp factor 8 (later limited to warp factor 6); (refit, estimated) warp factor 10

Jackill's

The Soyuz class starships were designated as an attack frigate or tactical frigate. The aft section of the primary hull had megaphaser mounts (rather than sensor pods) and had launch bays for fighter craft.

There were three models of Soyuzii, rolled out in 2274 (Mk I), 2284 (Mk II), and 2309 (Mk III), respectively.

Specs:

• Length: 234 m
• Width: 141 m
• Height: 68 m
• Displacement: (Mk I) 187, 193 mt; (Mk II) 201,478 mt; (Mk III) 208,755 mt
• Ship's complement: 429 officers and crew; 129 troops; 35 passengers
• Weaponry: (Mk I and II) 6 FH-10 phasers; (Mk III) 6 FH-11 phasers; (Mk I) 6 FMH-1 megaphasers; (Mk II) 6 FMH-5 megaphasers; (Mk III) 6 FMH-10 megaphasers
• Warp engines: Leeding FWG-2 (maximum safe cruising speed: warp factor 8; emergency speed: warp factor 9)
• Impulse engines: (Mk I) FIF-2; (Mk II) FIF-3; (Mk III) FIG-2

Kennedy Shipyards

The Soyuz class is seen as a derivative of the Miranda class and this type of vessel is called a "super" heavy destroyer. The aft hull section is said to house additional deuterium and antimatter stores. The class has a total of four type-2 pulse phaser cannons mounted at the hardpoints. (Kennedy Shipyards: Starfleet Vessel Miranda Class Starship USS Reliant NCC-1864: General Blueprints and Specifications)

This continuity also says that the class was in service 80 years past the canonical 2290 date, as late as the Dominion War.

Orion Press

In this continuity, the Soyuz class ships were introduced the same year (2271) as the similar-looking Voshkod class attack frigates. (Orion Press Lexicon 2008 Appendix I)

Specs:

• Length: 254 m
• Width: 151 m
• Height: 64 m
• Ship's complement: 64 officers, 315 crew
• Weaponry: phasers (6 banks of 2 cannons); megaphasers: (6 turrets with 2 cannons); photon torpedoes: 2 tubes

Star Trek: Avenger/Star Trek: Accord continuities

The Star Trek: Avenger and Star Trek: Accord fan fiction continuities subscribed to the Jackill's interpretation (i.e., the ship's having megaphasers rather than sensor pods, and of the rear of the extended primary hull containing launch bays for fighters). These continuities also continue using the Soyuz class starships past the canonical 2290 date and into the early 24th century.

Further, while Jackill's notes that the Soyuzii were commissioned in the mid-2270s, these two continuities see that as a refit and recommissioning date from a class (also named Soyuz) that was similar but used PB-31 or similar type warp nacelles available in the late 2250s.

USS Accord was said to be the last operational Soyuz-class vessel. It was decommissioned in 2315, nearly six decades after its commissioning. (Star Trek: Avenger: "The Final Curtain")
