D7 Battlecruiser

The classic Klingon cruiser, the D7 Battlecruiser is a stalwart defender of the empire and the basis for one of the most long lived cruiser lineages in history.

A worthy if aging opponent, the D7 was the counterpoint to the Federation Constitution Light Cruiser. The D7 Battlecruiser model is an effective warship design with a balanced weapons loadout. The ship does however does have less powerful shielding systems than those used by the Federation. Despite some minor flaws, the D7 Battlecruiser was the most powerful warship fielded by the major races of the Alpha and Beta Quadrants for some time. Its effectiveness in battle was well noted by other powers, most notably the Romulan Star Empire that traded cloaking technology in exchange for several pieces of Klingon technological data, including blueprints of the D7 Battlecruiser.

Design Notes:

Balancing this ship and remaining with breathing room for the K'T'inga Battlecruiser upgrade was difficult. I wanted the two ships to be different enough to represent an upgrade in quality without making the K'T'inga too strong. Also, this ship was the first Klingon ship to pose the dilemma of what to do about the obviously different photon torpedo launcher. First I thought about putting two photon torpedoes on, but I rejected that. Roman Alexander Perner (a great help throughout my early design work) mounted ion torpedoes on his versions, but I didn't care for this fix either. I ultimately decided on the heavy photon torpedo as an adequate abstraction of the larger Klingon torpedo tube.
