In the design tank, the Umhi’tagor class looked good. The class was the Romulan’s first serious attempt to modernize their battleship classes. Designed to be fast, well-armed and armored, the Z-13 seemed to meet all the programs design objectives.
The prototype was equipped with the RB-11 long range disruptors, giving the Z-13 “teeth”, especially in the forward and aft firing arcs. Three RPL-3 plasma weapons were also installed allowing the Sharp Talon to quickly maul any opponent that came within their reach. Significant armor and the efficient RSO shield system provided good protection.
However, once the two prototypes entered service in 2268, it quickly became apparent that the design had serious issues. The RWF-2 warp drive was considered under powered and slow with a top speed of only Warp 6. The vessel’s RIE-3 impulse drive, while powerful, still did not supplement the main power source sufficiently for more than a small percentage of the main weapons to be armed during combat drills.
Almost immediately, both prototypes were recalled for analysis. After six months, many long nights and the forced suicide of several designers, the warp nacelles were re-tuned to improve maneuverability. One of the forward firing plasma torpedoes was also removed, replaced with two RP-3 torpedo launchers giving field commanders greater flexibility in their weapon choices. The overall changes boosted the Type-2’s combat efficiency but did not address the power problem that plagued the design. The decision was made to terminate the program with the completion of the five remaining prototypes.
Of the 2 Type-1s produced, one was scrapped for analysis and the other converted to a Type-2. The 6 Type-2s remained in service until the introduction of the Z-1 Nova class of battleship.
The Z-13 was produced at the Remus shipyards.
