Piranha (Block 2) Light Cruiser

design by Pete Gray

I started this design months ago, after seeing how Lewis has done a few of the ships from the Challenge 61 article "Ships of the Black War." Please note that this design is my own personal modification of the Piranha in the article.

Overview: The Piranha class Light Cruiser was designed during the height of the Fifth Frontier War. The vessel was designed as a heavy anchor unit in light raiding forces and screening squadrons, and was intended to replace two other classes of cruiser. The original Block 1 ship was constructed around a massive meson gun, a gun so large that the ship could only muster 3G and J-3. When postwar analysis showed the ship too slow for its intended role, the Navy Ship Command ordered a redesign to supplement the slower version. The Block 2 Piranha was designed as a deep penetration and commerce raider, and has J-5, a range greater than the majority of the Imperial Navy's inventory.

Most Block 2s that served in the Imperial Civil War were built either by the Domain of Deneb, or Lucan's faction. The class became infamous in the latter's service as a Black War raider. The class has remained in production in the DoD/Regency Navy until the present day, and has been used heavily against Viral bases and shipping in Corridor Sector and the Great Rift. The class is scheduled to end main production in 1207.
