NOTES:
The S-15 represented a major push in exploration by the Romulan Star Navy. The class appears to be a modification of the S-3 class. Using the S-3 as a basis of the design seems to have been a cost-saving measure. The Type-1 was launched in 2259 and was far more heavily armed than it’s predecessor. It is estimated that up to 40 of these ships were produced.
The Type-2 was the first improvement to the design in early 2268. An enlarged computer allowed for the use of a RCB cloaking device and the increase in the main armament. Although heavier beam weapons were available at the time, the decision to include a light torpedo gave the vessel excellent combat capability when needed during it’s light duties. Only 20 Type-2s are know to have been built, but most Type-1s are thought to have been converted before the launch of the Type-3.
The Type-3, launched in 2269, did not fare well. The removal of the aft weapons and including of the RPL-1 plasma torpedo did not prove effective. Only three were built and all three were later rebuilt as the Type-4.
The Type-4 was the first real increase in firepower, with the long-range RB-5 and heavier RP-3 torpedo used in the offensive package. The S-15 would remain in production until late 2279 when production officially ended. However, as the S-15 retains the positive attributes that characterized it’s parent class, namely good speed and maneuverability, the class is expected to remain in service for some time.
Some 75 S-15s are known to be in service. Reports indicate that 2 Type-1s and 1 Type-2 have been destroyed in engagements with the Klingons. 2 Type-2s are reported to be operating in the Triangle as independent traders.
The class is named for a crustaceans found in the warmer waters of ch-Rihan. The animal is known for it’s strong shell and razor sharp claws.
