Background
D7 1


The D7 class Klingon battle cruiser served as the backbone of the fleet for several years during the 23rd century. Among the mission profiles designated for this class was that of scout ship.

By 2267, they were prominently featured in the Klingon Imperial Fleet, where they posed a serious threat to the security of the Federation and Starfleet.

The Romulan Star Empire later began using the same design by 2268.

According to the Star Trek Chronology the line regarding a Romulan-Klingon Alliance was added to "Reunion" to explain the Romulan use of D7s.

The K't'inga-class battle cruiser began to replace the D7 class during the 2270s. The D7 was finally "retired decades" prior to 2377.

Interest in these vessels by the Federation continued to appear well into the 2370s, as data on this class was commonly found within numerous Starfleet files.

NOTES:

1 - Depleting the MDC of the Main Hull will put the ship out of commission. All internal systems will shut down, including life support and internal gravity.

1B - Destroying hte Bridge will automatically switch control to main engineering in the engineering section. ONce control is established in the battle bridge efficiency of the vessel will only be affected as follows, -5 to all combat rolls and attacks per melee are halved.

2 - Destroying the sensor will deprive the ship of all forms of long range communications, radar and targeting. The range and targeting capabilities of the secondary systems are equal to that of a shuttlecraft at best. The ship can still operate, but is at -3 on initiative, -3 to strike, and number of attacks per melee of the weapon systems are reduced by half.

4 - Depleting the MDC of the the warp nacelles will force the ship to rely on its Impulse engines. Depleting the MDC of the main engines AND secondary engines will leave the ship adrift in space with very minimal movement allowed by its docking thrusters. If in an atmosphere, the ship will crash.

5 - Shields regenerate at 40 mdc per melee. Only if a generator is damaged will the ability for shields to regenerate be hampered
