Hello thank you for taking time out to review my inquiry. I would like to share these serious concept ship designs that are cannon and would complement BSG Deadlock.
The first is the Gunstar class Cygnus

The Colonial Gun Star is the pinnacle of combat engineering design. When Colonial engineers started drawing up the blue prints for this military vessel the goal was simple. Develop a ship able to bring the fight literally to the enemy foot steps and knock on the door. After several design developments Cygus Ship Yard (CSY) created a marvel master piece meeting Colonial Military Fleet exact specifications. Every aspect of war was used and incorporated into the Gun Star making it a multi-purpose/role ship. Its redesigned weapons system gives this ship its muscle making it superior in firepower. Enabling this warship to handle various missions its overall design makes this ship fast and highly maneuverable yet long-endurance in combat.
Primary mission of the Cygnus Class Gun Star is as follows intended to escort or give direct support of larger military vessels in the fleet, convoy or battle group and defend them. It's secondary mission to perform as a Command Control and Communications platform.
Scale: L: 695m W: 280m H: 93m
Tonnage: Variable
Speed: Variable
Power: Primary tylium energizers and advanced fusion reactors and generators. 2 reactors, 1 backup reactor, Auxillary Battery. Tylium fueled equipped and separate tanks for Solium fuel. FTL capable its jump range differs, but max is 80 before needing to refuel.
Crew Compliment:
Standard Crew: 800
Fleet Officer: 64

-Flak Cannons: 5 Port and 5 Starboard.
-Missiles: 12 Dorsal hatches, 6 Tubes each (Nuclear Warheads).
-Conventional Missiles: Ship to Ship. Housed in the mid-section of the ship where
-4 Large Cannons on the bow of the ship.

-6 Shuttles
The hangar bay can house a few extras ship as backs or storage for visiting ships on long distance missions. Also has 12 maintenance bay for repairs to small ships only.
Damage Control System: automated firefighting capability, managed by the Boroton Mist / Foam / Liquid control center. DCS has three stations the main is located in engineering, Secondary located in CIC and Auxiliary is forward of the landing control station. All ships in the Fleet have Damage Control Teams (DCT). These teams are part of the engineering department and are charged with the safety of the ship and are tasked with fire and rescue.
The second is the Assaultstar class Vanguard

Not all of the vessels of the Colonial Fleet are big bruising battlestars. In fact, there are a number of smaller vessels that make up the 150+ vessels of the Big Blue Machine. One of these important ships is the assaultstar. Originally designed as a light, maneuverable vessel to screen the more valuable battlestars from damage, the assaultstars also proved themselves in more prosaic duties like smuggling interdiction, search-and-rescue, and marine reconnaissance and assault support.
Most battlestar groups have 2-3 assaultstars attached to them, coupled with 2-3 of the smaller gunstars, and a tender. Assaultstars are also grouped in MRG (Marine Reconnaissance Groups) that are tasked with supplying marines to areas of operations including emergency response, disaster relief, and combat action.
The assaultstar class is an older model, the original models as old as thirty years in service, but they are nearly all still active as of the attacks. They carry up to a battalion of Colonial Marines for up to three months, which can be deployed using specialized Marine Landing Shuttles (uparmored standard shuttles.) The MLS can carry 25 marines and either a tank or two APCs or CAWS, or 50 marines in a drop.

HISTORY:
Demosthenes is part of BSG-55 (Pleiades), but is often released to detached duty for search & rescue and smuggling interdiction missions. “Old D” was constructed in 35AC, and is one of the older vessels in her class. She has a reputation for being “lucky.”
