The D-7 class battlecruiser was the standard cruiser of the Klingon Deep Space Fleet, and was based on the same basic spaceframe as the [[D-6 class (SFC)|D-6 class]. Less expensive than most other heavy cruisers, it lacked the full range of scientific capabilities and crew living conditions were spartan. In combat, the D-7 was noted for its superior turn radius and for its many transporters, which made for effective hit and run raids, and for boarding party actions. Introduced in 2250, the D-7 had a crew complement of 440, featured a capacity of eight shuttlecraft, four science labs, five transporters, and three tractor beam emitters; it was armed with two Type-F missile launchers, four banks of Type-3 disruptors, and nine banks of Type-2 phasers. The D-7 remained in service until 2282, when it was succeeded by the D-7B refit, introduced in 2270. The D-7B featured stronger shields; it replaced its Type-F missiles with Type-As, and added a bank of Type-3 phasers. The D-7B remained in service until 2297, when it was succeeded by the D-7K refit, introduced in 2285. The D-7K replaced its Type-A missiles with Type-B, and remained in service until 2301.

Also introduced in 2250, the D-7C command battlecruiser was a command version of the basic D-7 design, with improved shields and weapons, and an increased crew capacity of 470. The D-7C also featured seven transporters and five tractor beam emitters, and mounted two Type-B missile launchers, four banks of Type-3 disruptors, three banks of Type-1 phasers, six banks of Type-2 phasers, and two banks of Type-3 phasers. The D-7C remained in service until 2291, when it was replaced by the D-7L refit, introduced in 2279, which replaced two banks of Type-2 phasers with Type-1s. The D-7L remained in service until 2301.

The D-7D drone battlecruiser, introduced in 2287, was not intended as a long-range bombardment platform like the D-6D, but was an experiment to produce a more effective cruiser for general combat purposes. Had the class been considered a success, many or most of the existing D-7s would have been converted to the D-7D specifications. The D-7D's lack of rear-arc defenses was accepted by the captains, but rejected by the admiralty. The D-7D featured a capacity of eleven shuttles, and was armed with four Type-B missile launchers, four Type-3 disruptor banks, three banks of Type-1 phasers, and two banks of Type-2 phasers.

The Kareli Design Bureau, exploring further enhancements to the venerable D-7 spaceframe, incorporated several innovative design features into the D-7W heavy command cruiser, which was introduced in 2289. The most powerful D-7 variant ever produced, it had a crew complement of 500, featured even stronger shields, a capacity of ten shuttles, four science labs, five transporters, four tractor beam emiters, and was armed with two Type-B missile launchers, four banks of Type-3 disruptors, seven banks of Type-1 phasers, four banks of Type-2 phasers, and two banks of Type-3 phasers.

The D-7CT tactical command cruiser variant featured a capacity of five shuttlecraft, four science labs, seven transporters, two tractor beam emitters, and was armed with two Type-A missile launchers, four Type-3 disruptor banks, five Type-1 phaser banks, four Type-2 phaser banks, and two Type-3 phaser banks.

A final variant, the C-7 class heavy battlecruiser, was introduced in 2297.
