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 have been built. 31 Type 1s, 15 Type 2s and 21 Type 4s are in reserve fleets. 2 Type 1s and 1 Type 2s have been destroyed. 6 are reported missing. 4 Type 1s, 1 Type 2 and 2 Type 4s have been scrapped. 2 Type 2s were sold and operate as independent traders in the Triangle.
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.
